The unpalatable additives lurking in our food... but are they really bad for you?

Titanium in chewing gum, antifreeze in salad dressing and jet fuel in cereal: are they really THAT bad for you?

Food researcher Dr Stuart Farrimond says certain additives can be good
Avoiding ready-made and processed foods is the best way to eat healthily
Steer clear of chewing too much gum as it may not be entirely harmless 

There are lots of scary stories about the unusual ingredients added to foods to preserve them. From sand in sugar to flavour enhancers in chicken breasts and even jet fuel in cereal, there seems to be a whole host of unsavoury additives lurking in our food. However these ingredients are not always obvious from the additives, preservatives and extracts listed on the back of the packaging - couched in scientific terms too difficult to understand.

But according to science communicator and food researcher Dr Stuart Farrimond, some of these additions are not all that bad. He told: 'The truth is rarely as scary as the headline. 
'At the end of the day, eating plenty of fruit and vegetables and cooking with simple ingredients, while avoiding too many pre-made meals and processed foods is the best way to eat healthily. 'I think it's important to not cut out all treats - where would we be without chocolate and ice cream? Moderation is key.' Here Dr Farrimond explains what each one of those ingredients mean. 

Titanium dioxide in chewing gum

Listed as:  E171

Dr Farrimond explained:

'Titanium dioxide is a rather unexciting white powder that is used as a pigment to in foods, paints and sun creams to make them look whiter.  'You find it in tablets and capsules, cottage and Mozzarella cheeses, horseradish sauce, lemon curd and toothpaste. ">It is highly purified and used in small amounts in foods; it doesn't contain lead, as some website claim. On an ingredients list you will find it hiding as E171 and, although the European Union considers it safe, there has been some research that it may not be entirely harmless. 'It's been in foods for a long time and in the low concentrations found in foods it's almost certainly fine.  'The European powers-that-be are nevertheless going over all the latest evidence and reviewing whether it should still be allowed in food products at its present levels.  'If you're concerned, I suggest skipping anything that has E171 on the ingredients list - and go easy on the chewing gum, remembering to spit and not swallow.

Carcinogens BHA and BHT in frying oil. Can also contain TBHQ, used to make varnishes and resins

Listed as: BHA is E320, BHT is E321 and TBHQ is E319.

Dr Farrimond said: 'BHA probably is a carcinogen but only if you consume it at very high doses. In the levels it is found in food it is not something to worry about and some experts think it could even be good for us in small doses.  'BHA and its sister substance BHT are antioxidants- similar to some vitamins - and are added to some fatty foods to stop them going off so quickly.
Antifreeze in salad dressing Listed as: Propylene glycol or E1520

Dr Farrimond said:

 'Propylene glycol is not antifreeze. The similar sounding ethylene glycol is usually one of the main ingredients in antifreeze - and that is highly poisonous. That said, propylene glycol is an ingredient in some 'non-toxic' antifreezes because it is much safer than ethylene glycol. 'Propylene glycol is a clear liquid that tastes slightly sweet and it goes under the codename E1520 in Europe.  'It has been added to foods and medicines for about fifty years as it helps to keep them moist and long lasting.

Jet fuel in cereals with added vitamins 

Listed as: E321

Dr Farrimond said: 'This is a very useful antioxidant that is added to everything from cosmetics and fuel to some fatty foods.  'You'll see it listed as E321 on some foods. It is an anti-oxidant - like many vitamins and supplements 0 some experts think that in the low doses found in food it could be good for us and actually help fight cancer. Lots of helpful substances come from some strange places. Insulin for diabetics, for example, is grown in bacteria.  'Quorn meat substitute is a product of fungi and - yes - some vitamins and additives are produced from a petroleum base. It might sound scary, but it's exactly the same vitamin E molecule that is produced in plants – you are not consuming petrol.'

Sand in sugar

Listed as: Silicon Dioxide, silica or E551

Dr Farrimond said: Sand is mostly silicon dioxide but, then again, silicon dioxide is pretty much everywhere - in the earth, in water, in plants and in us.  'It is completely harmless and the silicon dioxide in food is refined and powdered. It's not the sort of thing you would normally add to your cooking, so the idea may put you off eating anything with it in even though no one ever died when sand got in their sarnie on the beach.

Wood pulp in various processed foods

Listed as:  Cellulose

Dr Farrimond said: Cellulose is the 'fibre' that you find in fruit and vegetables - helping to give it bulk. Cellulose isn't digested, it passes straight through us and helps to 'keep us regular'. Most of us don't get enough fibre in our diet because we don't eat enough greenery. Of all the food additives, this is one of the least worrying.

Chemical fillers in chicken breast

Listed as: Flavour enhancers and added protein

Dr Farrimond said: 'The amount of added water in supermarket meat is truly scandalous. It is quite normal for chicken breasts to have been 'plumped' with 10 to 20 per cent extra water, sometimes more.  'It's been done for years and while food manufacturers argue that it makes for a more succulent meat, it is really a crafty way to make cuts of meat seem bigger than they actually are. All the water comes off in cooking, and the meat will ultimately shrink back down to its real size. 'Plumped meats sometimes have some added extras, including added protein and flavour enhancers to make them taste a bit better - but it is the water that you really should be shedding tears over.  'Whole chickens aren't allowed to be plumped in the same way that cuts are, so buying a whole bird makes more economical sense. Check the label before you buy to see how much meat is really in your meat.'

Calorie Control Versus Exercise: Two Scientists’ Findings on Weight Loss

Going to the gym WON'T help you lose weight – you need to eat less: Study finds exercise alone is not enough to shed the pounds 

• Two experts have studied the link between exercise and obesity for years
• Trials show exercising and dieting is no more effective than dieting alone
• When people exercise, their appetite increases and they eat more food 
• The only way to lose weight is to eat fewer calories, they concluded

Most people hoping to shed a few pounds head straight for the gym.
But the miles they clock up on the treadmill may not actually help them lose any weight, scientists now claim.
Doing more exercise increases a person's appetite, and they tend to eat more food as a result, the researchers said.
Therefore controlling calories – with or without increasing physical activity - is the key to maintaining or losing weight, they concluded.

Dr Richard Cooper and Dr Amy Luke, both from Loyola University Chicago Stritch School of Medicine, have been studying the link between exercise and obesity for years. Writing in the International Journal of Epidemiology, they said: 'Physical activity is crucially important for improving overall health and fitness levels. But there is limited evidence to suggest that it can blunt the surge in obesity. '

This crucial part of the public health message is not appreciated in recommendations to be more active, walk up stairs and eat more fruits and vegetables.

'The prescription needs to be precise: There is only one effective way to lose weight - eat fewer calories.'

Numerous clinical trials have found that exercising as well as restricting calories achieves virtually the same weight loss calorie-restriction alone, they said.

And other studies show no link between the energy someone expends (through exercise) and subsequent changes to their weight. They added that only 'extremely small' proportions of the US population do enough physical activity to affect their long term balance of energy.

Therefore, they argue that that physical activity does not influence obesity, they said.

They concluded: 'While physical activity has many benefits, multiple lines of evidence lead to the conclusion that an increase in physical activity is offset by an increase in calorie intake, unless conscious effort is made to limit that compensatory response.'

Last year, Dr Michael Mosley, the brains behind the popular 5:2 diet, warned that exercise can actually cause us to gain weight. 'A lot of people think that when you exercise, you can eat what you want - and that the gym will make you happy,' he said.
But this is wrong.

He added: 'The key problem is that we reward ourselves with 'treats' after exercise - or have the "I've been to the gym, so I can eat what I want mentality". 'Exercise is a good way to keep weight off - but it's not a good way to lose it'.

'Going to the gym will burn calories - but way less than we think. '1lb of fat is 3,500 calories - and fat is more energy-dense than dynamite' - so to burn 1lb of fat you'd need to run about 38 miles.'

He cites the example of a muffin and latte - which many of us underestimate the calorie content of. 'If you run one mile, you burn roughly 100 calories,' he told presenters Ruth Langsford and Eamonn Holmes. 'A muffin contains around 500 calories - so you would have to run for five miles or walk for 10 miles to burn it off.' And when it comes to a latte - which has around 150 calories - it would be 1.5 miles of running or a three-mile (hour long) walk. 'That is why people never lose weight going to the gym in the long-run.

What's lurking in YOUR salad? Experts warn prewashed spinach still contains 90% of its bacteria and can cause food poisoning

Health experts have warned against eating pre-washed spinach.

They say commercial washing techniques fails to remove 90% of the bacteria.

Small peaks and valleys in baby spinach leaves could be a key reason why there have been numerous bacterial outbreaks involving leafy green vegetables, they say.

Greens are washed by commercial processes before they head to the grocery store. 

But these methods, which can include water and bleach rinses or irradiation, are not completely effective, says Nichola Kinsinger of the University of California.

She says scientists have estimated that 99 percent of food-borne illnesses from leafy greens can be traced back to disinfection issues. 

'In a sense the leaf is protecting the bacteria and allowing it to spread,' said Nichola Kinsinger, a post-doctoral researcher working with Sharon Walker, a professor of chemical and environmental engineering. 

'It was surprising to discover how the leaf surface formed micro-environments that reduce the bleach concentration and in this case the very disinfection processes intended to clean, remove, and prevent contamination was found to be the potential pathway to amplifying foodborne outbreaks.' 

As a result, as the leaves move through the processing facility after being rinsed the bacteria may continue to live, grow, spread, and contaminate other leaves and surfaces within the facility.

The researchers in the Bourns College of Engineering found that because of the varied topography of the spinach leaf nearly 15 percent of the leaf surface may reach concentrations as low as 1000 times that of the bleach disinfectant being used to rinse it.

'Despite current disinfection rinsing, bacteria are surviving on the leaf and causing cross contamination, resulting in the numerous outbreaks we hear about in the media,' Kinsinger said.

'Pathogens can come from irrigation waters or from water used during processing, and they can adhere to spinach leaves. 

'If these bacteria are not all killed in the disinfection process, they can continue to live, grow, spread and contaminate other surfaces within the facility and other leaves.'

Using a parallel-plate flow chamber system that Walker developed, the researchers tested the real-time attachment and detachment of bacteria to the outer layer of spinach leaves. 

At low bleach concentrations, the bacteria fell off the leaves, but remained alive. At the higher concentrations used commercially, however, all of the bacteria were killed. 

'This result was perplexing,' Walker says. 

 'Our experiments were telling us that commercial bleach rinses should be much more effective than they are. But then we studied the leaf itself in more detail.' 

Currently, the industry standard is to add 50 to 200 parts per million of bleach to the water used to rinse leafy green vegetables. 

But that is just a recommendation, not a requirement or regulation, Kinsinger said.

For the research, Kinsinger and Walker designed a parallel plate flow chamber system to evaluate in real time the attachment and detachment of pathogens to the spinach in realistic water chemistries and flow conditions.

Their work focused exclusively on baby spinach, however the issue of reduced bleach concentration across the leaf surface and other surfaces within the processing facility translates beyond the specific scenarios tested and demonstrates the limitation of bleach disinfection causing significant concern over public health.

Future research will focus on a broader range of foods, surfaces in processing facilities and pathogen types, Kinsinger said.

Despite their findings, Kinsinger notes that the United States has one of safest food supply system. Still, she says, 'I recommend rinsing those leaves.'

Five muscle groups that are too often ignored at the gym

Having a training plan is crucial. A plan keeps you focused, allows you to track your progress and gives you objective data to understand why you are, or are not, reaching your goals.

However developing a strength routine can be stressful, intimidating and confusing.

Too often people’s default program is cardio followed by a few push-ups and crunches. Alternatively, those who spend time in the weight room prioritize exercises such as bench press and shoulder press.

Any activity at all is commendable, but the above exercises primarily train the front of the body and can contribute to a rounded posture and back and shoulder injuries.

So, whether you’re a gym newbie, or have been training for years, make sure your plan is balanced. The five muscle groups below are a critical part of any plan, but are typically overlooked. Don’t be typical; train smart.

1. The posterior chain.

This is also known as the back of your body, running from the back of your head to the back of your heels. Prioritize strengthening your posterior chain, specifically your back and glutes (bum).

Do one upper-back exercise for every chest exercise. If you have been overtraining your chest for years, for the next two months do two upper-back exercises for every one chest exercise.

Chest exercises include push-ups, the bench press and flys. Upper-back exercises include any type of row, lat pull downs, pull-ups and reverse flys.

Do at least one lower-back exercise such as the bird dog, back extensions or supermans.

Strengthen your glutes with multijoint exercises such as deadlifts, squats and bridges.

2. Balance and feet exercises.

Balance and feet strengthening exercises require proprioception – the body’s mind/body loop, which allows the brain to register where the body is in space, and then to tell the body which muscles to “turn on.”

Decreased proprioceptive abilities, and/or weak feet, can contribute to a plethora of injuries including plantar fasciitis, ankle sprains and knee and hip pain.

When you run, your feet and brain need to communicate so your feet can safely negotiate the terrain. Otherwise, you trip and fall. And when your proprioception is poor, your body compensates by using vision; you look down to know where your feet are. Over time, looking down will round your spine.

Incorporate unstable equipment such as a bosu, resistance ball or balance board into your routine. Try some squats or push-ups on the bosu. Do some balance work barefoot to strengthen your feet. Try standing on one leg with your eyes closed.

3. Rotator cuff exercises.

Your rotator cuff is made up of four small muscles that originate on your shoulder blade. Together, they help stabilize your arm bone in your shoulder socket and help maintain proper posture.

Try band external rotations. Stand against the edge of a door frame, shoulder blades on either side of the frame. Hold a resistance band, palms up and arms at 90 degrees. Draw your arm bones back in your shoulder sockets.

Then use the muscles around the back of your shoulders to rotate your hands out to the side. As your arms move, squeeze your shoulder blades slightly around the door frame. Repeat 15 times.

4. Wrist exercises.

Weak wrists are often the limiting factor when people are trying to improve their pull-ups, push-ups and deadlifts. Strengthen your wrists by changing your hand position or the width of your grip when you use free weights or barbells. For example, use a thicker bar when doing bench press or bent-over rows; do biceps curls with your palms down; triceps cable presses with your palms up; or put Fat Gripz around dumbbells to increase the diameter of what your hands have to hold.

5. Mindfully do functional multijoint exercises.

Done correctly, functional multijoint exercises such as planks, deadlifts, squats, wood chops and bird dogs are an integral part of any program. They work the entire core, integrate the trunk into the rest of the body and prepare the body for real life.

Unfortunately, most people just go through the motions. To get the most out of any exercise, to improve your biomechanics and to properly train your core, you have to pay attention to how your body is positioned.

For example, when you are doing exercises such as squats and deadlifts, think of them as a core challenge, a moving plank. Focus on stabilizing your spine, don’t let your back arch or round as you move.

Regardless of your exercise selection, always progress appropriately, ask a gym employee for instructions when needed and listen to your body.

How to keep your diet and fitness goals on track through summer

Making healthy choices during the summer can be a challenge. I get it – it just feels “right” to indulge while relaxing at the cottage or sitting on a patio. But it is possible to enjoy your summer and maintain a healthy lifestyle; it just takes mindfulness and advance planning.

First, analyze where you are most likely to veer off track.

Do you stop exercising any time your routine changes? Are you a social eater, or do you snack when you are alone? Do you use unhealthy food as an instant energy boost when you are tired or bored on road trips?

Tailor your game plan to your individual needs; prepare for your trigger situations in advance.

If you indulge while traveling when you’re unprepared and tend to grab something (anything!)

Don’t let yourself fall into the trap of “having to” buy unhealthy snacks.

Research healthier restaurants en route, or, better yet, pack a cooler full of nutritious snacks.

For longer road trips, locate in advance the grocery stores you will pass. Stop and buy fresh fruit, vegetables and prepared deli food. Or purchase fresh fruit and vegetables from roadside stands. Always have a water bottle so you don’t get dehydrated, and use that water to wash any produce.

If you tend to snack when bored

Download an audio book or podcasts to keep you entertained.

If you are a social eater

Live by my “love it” rule. Don’t deprive yourself – life is worth living – but don’t mindlessly eat. Treat yourself to a reasonable portion of something that you love. Pick one treat. Don’t have chips, beer and wings. If you love beer, have one with a healthier meal. If you don’t love beer but you love wings, drink a low-calorie alcoholic beverage or water and indulge in a few wings.

Stay hydrated. That way you won’t mistake dehydration for hunger.

If you are attending an event at someone’s home, offer to bring something. That way you have at least one healthy option.

Before going to a restaurant, preview the menu online and decide what you will eat. On arrival, don’t look at a menu. Order your predetermined choice.

Place your cutlery down between bites so that your brain has time to register that you are full.

If you tend to slouch on vacation

Don’t let a change to your routine be an excuse not to exercise. You don’t need a gym to get a good workout; you can move and be active anywhere!

To fit in cardio while travelling, try fartlek intervals. Warm up for 10 minutes, then pick a random landmark to sprint towards. If you are swimming, sprint for a certain number of strokes. Once you hit your landmark or your stroke count, slow down and recover. Repeat for 10 to 30 minutes. Finish with a cool-down and then stretch.

Or explore your vacation destination on foot or on a bike. Use the pedometer on your phone, or buy a tracking device and aim to get 10,000 steps per day.

Fit in strength training. Most hotels have a gym, but if yours doesn’t, or if you’re staying with family, pack a resistance band. Train in your bedroom. Bands are light, inexpensive, highly portable and offer a full body workout. Try attaching the band to the bedpost to do standing rows, or standing on it to do biceps curls. If you don’t like the band, use your body weight to do squats, lunges, push-ups, planks and V holds.

The main take-away is that it is always possible to make healthier choices; it just takes mindfulness and some advance planning. If you make a choice you are not proud of, don’t feel guilty. Instead, use it as learning experience so you can make a more informed choice next time. Also, remember that just because you make one indulgent choice doesn’t mean you have to indulge constantly. Try to keep in mind that your future self will be happier – and have fewer bad habits to break after vacation – if you follow the “love it” rule and remember that moderation is key.

How To Trick Yourself Into Working Out Harder Without Even Realizing It

Since the invention of the Walkman, active people have shown that staying entertained is a big key to fitness success. Now there's evidence to suggest interactive entertainment actually can help you exercise harder and boost your mind.
University of Florida researchers recently reported that brain games while cycling can improve thinking ability and boost speed by 25 percent. So you get to have more fun, pump up your brain and enjoy significantly more physical benefits.
The researchers asked a group of older adults to use stationary bicycles while performing mental tasks that ranged from saying "go" whenever a blue star appeared on a screen to solving math problems. They discovered a sweet spot of difficulty that was just challenging enough to keep brains occupied but just simple enough to not interrupt the workout.
Imagine your brain as an engine. Certain physical activities (walking, running, dancing) ask for a lot of your brain's power to calculate stride, balance, limb coordination and more. Other activities (cycling, squats, push-ups) require less brain power because they're simple to do. The trick is to multitask by pairing a simple physical activity with a more challenging brain task or pairing a complicated physical activity with an easier brain task. You want the engine running at full power but not overheating.
Finding that balance might seem tough, but you don't have to do it alone. Here are four easy ways you can work your brain and body together for more fitness firepower.

Group fitness classes

Providing a variety of exercises that keep participants' minds humming is part of a group fitness instructor's job. Classes like yoga, BOOM and Zumba all are designed to improve strength and cardiovascular health while engaging participants' minds with instructions and coordinated movements.
Working with an instructor and classmates, your brain is treated to social interaction, changing paces, different physical poses and new exercises that keep things interesting.

Podcasts

If you prefer to exercise on your own, try pairing stationary cycling or a treadmill workout with a podcast.
Podcasts are pre-recorded audio shows you can download on portable devices, such as smartphones or tablets. Whether you're interested in sports, history, music, movies, trivia or news, there's a podcast for you.
You'll be amazed how quickly a 30-minute walk passes when you're being entertained and informed by your favorite podcast. To find podcasts, use an online service such as iTunes or SoundCloud.

Hiking

The changing landscapes of hikes are a natural way to keep your mind busy. Wildlife and plant life provide an interesting backdrop for your eyes, and adjusting to terrain keeps your muscles guessing and your brain focused on balance.
To make things more interesting, incorporate a camera for snapping photos on your hikes. Or bring binoculars along for bird-watching. Linking the names and characteristics of the world around you is a terrific way to busy your mind while you're working your body.

Sports

Are you competitive person? Do you enjoy teamwork? Playing a sport could be the perfect fit for you. Sports like softball, pickleball and golf improve your muscle tone, endurance and motor skills while also engaging your mind in strategy, calculation and positioning.
If you've played a sport before and enjoyed it, why not start again in an adult league or organize friends to play?
Or, if you're looking to try a sport you haven't played, ask friends who may have played. Some key factors to consider when choosing a sport include:

• What sort of experience, skills, or fitness are needed to start?
• Do you need to purchase any special equipment?
• Where is the sport played? Can you play locally?
• What time are practices or games scheduled? Are there evening or weekend options that work with your schedule?
• Are there fees associated with participation in teams or leagues?
• What is the best way for a beginner to get involved?

No matter which multitasking workouts you choose, the key is to have fun. If you're feeling bored, it might be time to change up your fitness routine. Remember that fitness is a lifelong journey. What interested you before might not interest you now, and your tastes forever will evolve.

The wonders of WATERMELON: more than just delicious and refreshing...

The question is, why is there so much craze for the watermelon? At first glance, it may seem like nothing more than a big ball of water.  We all know that there is nothing more refreshing than a big, chilled wedge of watermelon on a hot, summer day and it does sport a stylish scientific name of Citrullus Lanatus, but what’s the real reason so many people flock to grocery stores every summer to buy a big, awkward fruit like this one? Well, it is hard to narrow it down to a single reason; there are actually a lot of them.

Watermelon is now the most-consumed melon in the US (followed by cantaloupe and honeydew). This cousin to cucumbers, pumpkins, and squash is thought to have originated in Egypt close to 5,000 years ago, where it is depicted in hieroglyphics. 
As for accessing the total medicinal benefits of watermelons, it is highly dependent on the variety of watermelon and the ripeness. Beta carotene and lycopene is usually bio-available in the highest quantities once the watermelon is completely ripe, and don’t be afraid to eat some of the watermelon rind; there are quite a few nutrients in there as well, particularly the roughage and fiber.

6 Watermelon Facts That Might Surprise You

1. Watermelon Has More Lycopene Than Raw Tomatoes

Lycopene is a powerful carotenoid antioxidant that gives fruits and vegetables a pink or red color. It's most often associated with tomatoes, but watermelon is actually a more concentrated source. Compared to a large fresh tomato, one cup of watermelon has 1.5 times the lycopene (6 milligrams (mg) in watermelon compared to 4 mg in a tomato).

2. Watermelon Juice May Relieve Muscle Soreness

If you have a juicer, try juicing about one-third of a fresh watermelon and drinking its juice prior to your next workout. This contains a little over one gram of l-citrulline, an amino acid that seems to protect against muscle pain.
One study found that men who drank natural unpasteurized watermelon juice prior to their workouts had reduced muscle soreness 24 hours later compared to those who drank a placebo. You do need to be careful with drinking watermelon juice, though, as it contains a significant amount of fructose. It may be better to eat the entire fruit, or opt for these other tips to prevent muscle soreness.

3. Watermelon Is a Fruit and a Vegetable

Remember how watermelon is related to cucumbers, pumpkin, and squash? That's because it's part vegetable and part fruit (it's a sweet, seed-producing plant, after all). The other clue that watermelon is both fruit and vegetable? The rind is entirely edible…

4. You Can Eat Watermelon Rind and Seeds

Most people throw away the watermelon rind, but try putting it in a blender with some lime for a healthy, refreshing treat. Not only does the rind contain plenty of health-promoting and blood-building chlorophyll, but the rind actually contains more of the amino acid citrulline than the pink flesh. 
Citrulline is converted to arginine in your kidneys, and not only is this amino acid important for heart health and maintaining your immune system, but it has been researched to have potential therapeutic value in over 100 health conditions.
While many people prefer seedless watermelon varieties, black watermelon seeds are edible and actually quite healthy. They contain iron, zinc, protein, and fiber. (In case you were wondering, seedless watermelons aren't genetically modified, as they're the result of hybridization.)

5. It's Mostly Water

This might not be surprising, but it's still a fun fact; watermelon is more than 91 percent water. This means that eating watermelon with you on a hot summer day is a tasty way to help you stay hydrated and avoid dehydration (it's not a substitute for drinking plenty of fresh water, however).

6. Some Watermelon Are Yellow

The Yellow Crimson watermelon has yellow flesh with a sweeter, honey flavor than the more popular pink-fleshed Crimson Sweet. It's likely that yellow watermelon offers its own unique set of nutritional benefits, but most research to date has focused on the pink-fleshed varieties.

Health Benefits of Watermelons

Kidney Disorders: Watermelons contain a lot of potassium, which is very helpful in cleaning or washing out the toxic depositions in the kidneys. Moreover, it is helpful in reducing the concentration of uric acid in the blood, thereby reducing the chances of kidney damage and the formation of renal calculi in that organ. Added to this, being high in water content, it induces frequent urinating, which is again helpful for cleaning of the kidneys. Also, the anti oxidants present in watermelon ensure good health of the kidneys for a long time, and reduce signs of premature aging like wrinkles and age spots on the skin.
Prevents Heat Stroke: Watermelon is effective in reducing both your body temperature and blood pressure. Many people in tropical regions eat this fruit every day in the afternoon during the summer to protect themselves from heat stroke. In India, you will find the fruit being sold by vendors in almost every street during the summer season. The high amount of water contained in watermelon also stimulates a release of excess liquid in the form of sweat, which cools your body further during hot summer days.
High Blood Pressure: The good amount of potassium and magnesium that is present in watermelons is very beneficial in terms of bringing down blood pressure. Potassium is considered a vasodilator, meaning that it releases the tension of blood vessels and arteries, thereby stimulating increased blood flow and reducing the stress on the cardiovascular system. The carotenoids present in these fruits also prevent hardening of artery walls and veins, thereby helping to reduce blood pressure and the chances of blood clots, strokes, heart attacks, and atherosclerosis. 
Prevents Cancer: Watermelons have been in the public eye more and more in recent years, primarily because of their impressive level of lycopene, a carotenoid phytonutrient compound that is increasingly being linked to cancer prevention. As the years go by and the studies continue to bring in consistent results, lycopene has been shown to significantly reduce the risks of prostate, breast, colon, lung, and endometrial cancer. All in all, between the antioxidant potential of vitamin C and the impact of lycopene, watermelon is a great anti-cancer fruit!

Diabetes: Diabetic patients, who are supposed to have a low energy and low sugar diet, often complain about starving since they don’t get to eat their staple diets, which gives them the feeling of being half fed. Watermelons can be a good supplement for them. In spite of being sweet in taste, a thick wedge will give you very few calories, since ninety nine percent of its total weight is composed of water and roughage. Moreover, the various vitamins and minerals such as potassium and magnesium help in proper functioning of insulin in the body, thus lowering the blood sugar level. Arginine, another component found in watermelons, is very effective at enhancing the impact of insulin on blood sugar. Diabetic patients can also have curries, steaks, and salads made from water melon rinds, which are even lower in sugar.
Heart Care: Lypocene, a carotenoid found in abundance in watermelon, improves cardiac functions. Beta carotene, known for its remarkable antioxidant and anti-aging properties, also keeps you young at heart and prevents age-related cardiac problems. The roughage in water melon and its very low energy, along with help from vitamin-C, carotenoids and potassium (potassium cuts the risk of a heart attack), helps to reduce cholesterol and keep your heart safe from a variety of dangerous conditions.
Macular Degeneration: Don’t worry about eye health and macular degeneration if you eat plenty of watermelon, because between the beta carotene, vitamin-C, lutein, and zeaxanthin, your eyes are well protected. They will ensure protection of your eyes from age-related blindness and degeneration, and these antioxidants will protect your eyes from other age-related ailments such as drying up of eyes and optical nerves, as well as glaucoma.
Impotence: Arginine, present in watermelon, is beneficial in curing erectile dysfunction, and the stimulating nature of the chemical can boost libido, reduce frigidity and give a kick start to your love life, after you enjoy a few slices of watermelon together!
Other Benefits: Lypocene is found to be effective in repairing damaged tissues. Watermelon seeds are rich in beneficial fats and proteins. Watermelons also contain phytonutrients which have very good effects on the health and proper functioning of internal organs, eyes, and the secretion system.

Commercial fruit juice and smoothies can be a risk to health

We may think that we are giving health a good turn by opting for fruit juice or a smoothie instead of soda pop, but health advocates warn that this in not a sound choice. Linked with obesity and type 2 diabetes, these drinks are often a disease promoting agent in disguise. Masquerading behind a facade of wholesomeness, fruit juice and smoothies contain high levels of harmful fructose and synthetic additives. In response, nutrition experts warn that if we want to avoid health issues in the future, these beverages should be given a wide berth.

The risks of ‘healthy’ beverages
A significant player in the soaring rates of obesity and type 2 diabetes, sugar of all kinds (especially fructose) is a health disaster. Barry Popkin, a professor of nutrition at the University of North Carolina, states that “smoothies and fruit juice are the new danger,” in an interview with The Guardian.
In 2004 Barry Popkin and George Bray pointed the finger at high fructose corn syrup in soft drinks, causing a huge headache for the big manufacturers, including Coca-Cola and Pepsi. The two scientists had identified sugar-sweetened soft drinks, full of calories and consumed between meals, as a major cause of soaring obesity in developed countries. But they argue that as people change their drinking habits to avoid carbonated soft drinks, the potential damage from naturally occurring fructose in fruit juices and smoothies is being overlooked.

“Smoothies and fruit juice are the new danger,” said Popkin. He added: “It’s kind of the next step in the evolution of the battle. And it’s a really big part of it because in every country they’ve been replacing soft drinks with fruit juice and smoothies as the new healthy beverage. So you will find that Coke and Pepsi have bought dozens [of fruit juice companies] around the globe.”
Coca-Cola owns Minute Maid juices in the USA and Innocent smoothies in Europe while PepsiCo has Naked juices in the USA and Tropicana in Europe.

Drink vegetable juice, Popkin advices, but not fruit juice. "Think of eating one orange or two and getting filled," he said. "Now think of drinking a smoothie with six oranges and two hours later it does not affect how much you eat. The entire literature shows that we feel full from drinking beverages like smoothies but it does not affect our overall food intake, whereas eating an orange does. So pulped-up smoothies do nothing good for us but do give us the same amount of sugar as four to six oranges or a large coke. It is deceiving."
All sugars are equal in their bad effects, says Popkin – even those described on cereal snack bars sold in health food shops as containing “completely natural” sweeteners. “The most important issue about added sugar is that everybody thinks it’s cane sugar or maybe beet sugar or HFC syrup or all the other syrups but globally the cheapest thing on the market almost is fruit juice concentrate coming out of China. It has created an overwhelming supply of apple juice concentrate. It is being used everywhere and it also gets around the sugar quotas that lots of countries have.”
In a survey of sweeteners in US food products between 2005 and 2009 for a paper published in 2012, Popkin and colleagues found that fruit juice concentrate was the fifth most common sugar overall and the second most common, after corn syrup, in soft drinks and in babies’ formula milk.

“All the long term studies on fruit juice in anything show the same kind of effect whether it’s a smoothie or natural [juice] and whether it’s a diabetes or weight gain effect,” Popkin added.
Further evidence supporting the theory came last week from a study published by the British Medical Association.
Researchers from the UK, USA and Singapore found that, in large-scale studies involving nurses, people who ate whole fruit, especially blueberries, grapes and apples, were less likely to get type 2 diabetes, which is obesity-related, but those who drank fruit juice were at increased risk. People who swapped their fruit juice for whole fruits three times a week cut their risk by 7%.

Fructose is particularly troublesome, as it bypasses the body’s satiating signals, which encourages overconsumption and subsequent weight gain along with insulin resistance. It also increases uric acid levels, which promotes metabolic syndromes like hypertriglyceridemia. Fruit juices and smoothies contain concentrated forms of fructose, giving rise to a vicious cycle of blood sugar imbalances.

As observed by Popkin, when all is said and done, we would be better off consuming vegetable juice or whole fruit.

Summertime superfoods: Best foods to beat the heat

Staying hydrated is a key component of healthful living, as water comprises approximately 60% of our body weight. However, as we get older—and as the weather gets warmer in summer—it can become more difficult to stay hydrated. As we age, mechanisms for triggering fluid intake (i.e., feeling thirsty) weaken, and water retention capability changes, which can lead to serious consequences.

According to the Mayo Clinic, dehydration, which occurs when you lose more fluid than you consume, can lead to severe complications including heat injury (such as heat exhaustion or the more severe heatstroke), swelling in the brain, seizures, kidney failure and shock. Dehydration can even affect your mood, energy levels, ability to focus, alertness, and short-term memory.

The best treatment for dehydration is prevention; by drinking water and other fluids throughout the day, especially after strenuous activity or profuse sweating, staying hydrated during summer is a snap.

6 super-hydrating fruits and vegetables

But drinking water isn’t the only way to keep your fluid levels high. While warm summer weather makes hydration all the more important, it also means an abundance of super hydrating fruits and vegetables that can contribute to your fluid intake and give you a boost of nutrients to boot! Check out the list below for some ideas as to what to pick up on your next grocery run.

Cucumbers 
At approximately 96% water, it’s no wonder that juicy, crunchy cucumbers are hydrating. Toss sliced cucumbers on a salad or add them to a pitcher of water for a refreshing burst of hydration. Grate cucumbers and mix with Greek yogurt, lemon juice, garlic and dill to make a tasty tzatziki dip for fresh veggies and pita chips.

Celery

Celery is well known for being mostly water (and rightly so, at 95%), but this crunchy vegetable also packs a phytonutrient punch and supports digestive tract health due to its high fiber content. Cut celery stalks into sticks to dip in hummus or tzatziki, top with peanut butter and raisins for a classic snack, or add to a chopped salad for extra crunch.

Spinach

A good source of vitamins A and K, phytonutrients, such as carotenoids, flavonoids, and phenols, as well as iron, fresh spinach is also 92% water. Use spinach as the base for a summer salad, add to green juices, or pack leaves into a sandwich.

Tomatoes

A true summer fruit, tomatoes are 94% water and, like spinach and broccoli, are high in phytonutrients. In addition, tomatoes contain beta-carotene and lycopene, two antioxidants that have both been linked to prostate cancer prevention and may help reduce damage caused by sun exposure. Add tomatoes to salads, blend with other vegetables to make a refreshing salsa or gazpacho, or dice and toss with basil, garlic, balsamic vinegar and olive oil for a tasty bruschetta mix.

Grapefruit

Known for its high vitamin C content, tart grapefruit boosts immune function and may reduce cholesterol and triglyceride levels. At 91% water, grapefruit is especially refreshing in hot summer weather. Peel, segment, and toss in a salad, juice and enjoy, or make grapefruit lemonade.
Grapefruit is contraindicated for consumption with many medications, so check your medication labels or ask your doctor before adding grapefruit to your diet.

Watermelon

Last but not least, watermelon, at 92% water, is a summer staple. Watermelon contains lycopene, vitamin C, and beta-carotene, to name but a few nutrients. However, to reap the most antioxidant goodness from this melon, allow watermelon to ripen fully before consuming. Puree chilled watermelon and add to lemonade for a refreshing beverage, slice and eat, or arrange with basil and feta cheese for a refreshing salad.
While staying hydrated in summer is crucial, there’s no reason it can’t also be fun. In addition to drinking water, fruits and vegetables like those listed above are a great way to keep your fluid levels high and sneak in some extra nutrients.

Cool Down With A Hot Drink? It's Not As Crazy As You Think

Urban myth or scientific fact: does drinking hot drinks on a scorching summer's day really cool you down? Well, scientists do say sweating is the best way to stay cool.




It's 40 degrees Celcius and oppressively humid. You pull yourself up from your sweat-drenched chair and head to the kitchen … to brew yourself a nice steaming hot mug of tea.
Sounds a bit wrong doesn't it? Most of us would be more likely to reach into the fridge for a cold drink. But plenty of people in India apparently sip hot tea to stay cool in the warmer months. Are they crazy, or can a hot drink actually cool you down?
In some circumstances it might, scientists say, because it could trigger a level of sweating that may more than compensate for the added heat of the drink.
But it would depend on a lot of things, including the temperature of your hot drink, how much you consume, and the temperature and humidity of your immediate environment.

Cool theory behind hot drinks

Drinking a hot drink on a hot day might seem like a strange choice, but it's likely to cause only a very tiny blip in your core body temperature, says Professor Robin McAllen a neuroscientist at the Florey Institute of Neuroscience and Mental Health in Victoria.
That's because the amount of hot fluid in say a cup of tea is relatively small compared to the amount of fluid in an adult's body, McAllen says. (The same goes for the cooling effect of a cold drink.)
However, drinking hot tea still activates temperature sensors that trigger sweating. And sweating is a key mechanism our body uses to cool us down.
The University of Sydney's Dr Ollie Jay, who researches how the human body responds to heat, says a hot drink can indeed trigger a net cooling effect through excess sweating.
But there is a crucial caveat: the sweat needs to be able to evaporate to produce a cooling effect.
If it doesn't, and the extra sweat just drips on the ground, then you are no better off.
In other words, if you're exercising hard or in a very hot and humid environment where you're sweating more quickly than it can evaporate, it wouldn't be wise to increase your sweat rate further by having a hot drink. You'd be better off sticking to a cold one.
" If you drink a cold drink that's colder than your body, you'll shunt some heat into that fluid to warm it up," Jay explains.
"You lose heat to the fluid, and that's good because it increases the overall amount of heat you lose.
"The trouble is, it is compensated [for] by us reducing the amount we sweat onto the skin surface," he says.
It turns out when you consume a hot drink, you produce much more sweat relative to the small amount of heat added to the body.
"If all of that sweat can evaporate, then I am better off with a hot drink," says Jay.

Icy cold can make us hotter

Jay and his colleagues have just completed a study, not yet published, looking at slushies, drinks made of finely crushed ice.
Interestingly, they found that drinking an icy drink can make you hotter than a drink that's 37 degrees C, our normal body temperature.
This is because the icy drink is so cold it may shut down the body's sweating mechanism to the extent your body ends up storing more heat.
"With the slushy, because the stimulation for reducing sweating is so strong, we actually seem to over-compensate," says Jay.
"The reduction in evaporation of sweat from the skin is greater than the extra heat you shunt into the slushy to warm it up inside your body."
 

So what to drink?

So what sort of drink should you reach for on a hot day?
A hot drink is okay as long as the extra sweat it causes can evaporate.
"If it's hot and you do want to drink a hot drink and you don't mind sweating, then you could drink it with a cold fan blowing on you to help the sweat evaporate," Jay suggests.
But the best advice is to drink fluids at a temperature that's most palatable to you, says Jay.
That's because most of us don't drink enough when it's hot, yet we need to if we are to avoid dehydration and ultimately the onset of heat-related illness or increase in cardiovascular strain.
"Not many people are going to want to drink one-to-two litres of hot fluids but drinking one-to-two litres of cold fluids is a lot easier," says Jay.

Cold weather may spur weight loss

Feeling the January chill? Well, being cold isn't all bad. Scientists have found that exposing yourself to cold temperatures regularly could speed up weight loss.

It turns out there just might really be a way to burn calories more efficiently without slaving away at the gym or (god forbid) turning down dessert. The trick barely takes any effort: Just step outdoors or lower your thermostat, and you could be golden — if the newest research from the Center for Integrative Metabolic and Endocrine Research at the Wayne State University School of Medicine in Detroit, Michigan, checks out. 

To get how all this works, you need to know a bit about fat: When you eat more calories than you burn, your body stores the leftovers as white or brown fat, explains James Granneman, Ph.D., a scientist at Wayne State University who co-authored the new research. White fat can accumulate in your tissues, cause inflammation, and mess with your health, while brown fat creates energy more efficiently, generates heat, and excretes a mix of hormones that further promote energy metabolism. Because of this, it's in your best interest to have more brown fat than white fat.

To figure out what controls that brown-to-white fat ratio, Granneman and his colleagues assessed the body fat of mice before and after exposing them to 40-degrees Fahrenheit temperatures for one week straight. To put this in perspective, that's the temperature of the average refrigerator.

The cold temperatures favored brown fat and made white fat act a little more like brown fat, according to Granneman. The likely culprit is adrenaline, the same hormone and neurotransmitter that your body spews out when you're scared. (Which makes sense — just thinking about spending a week in a Sub-Zero is enough to scare anyone shitless.)

Even if you could handle a week in near-freezing temperatures, which you'd need to do to give your brown fat a leg up, it probably wouldn't boost your calorie burn enough to significantly affect your weight (or your health), says Granneman, who co-authored human research on the topic. But scientists are still digging around for ways to enhance the benefits of brown fat, he adds.

The bottom line is that all fat isn't equally bad — and that while winter weather is a bitch, chilly temperatures could, at least in theory, help your fat behave (even just a bit).

Take fitness outdoors this winter

Winter activities are a great way to mix up your fitness program and beat the winter blues. Get creative this winter and even if you can’t get to the gym, add fun new activities that your whole family can enjoy.
To make the most of your winter workouts, begin by changing your attitude toward the cold. With some planning, appropriate clothing and a spirit of adventure, winter outdoor fitness can be fun and effective.
Go out and play: Whether you have children or just act like a child, play is good for your heart and soul. Building a snowman is functional training and builds mobility and strength. Depending on how big you build it, you may burn as many calories as weightlifting or jogging. The bigger the snowman the more strength benefits you get. A vigorous snowball fight will burn up calories and work your whole body. And if you’re not into these activities, make snow angels. It’s good for flexibility and will elevate your heart rate.

Take up a winter sport: Skating is a fantastic non-impact cardiovascular sport. An outdoor skate feels invigorating without impact. If your joints can’t take running; skating and cross-country skiing are great alternatives. These gliding activities train balance, mobility and co-ordination. Cross-country skiing is one of the best calorie burning activities, as it requires both upper and lower body in the movement. If you don’t know how, don’t worry as these activities are easy to learn.
When the snow falls, snowshoeing is one activity that burns mega calories and is an excellent cardiovascular sport, burning equivalent or higher calories then running depending on your intensity and the snow conditions. Snowshoeing is one of the fastest growing winter sports. Not only is it an amazing fitness activity, it is convenient and easy to learn. If you can walk you can snowshoe.
Snowshoeing is great conditioning for running. Snowshoes add resistance, yet there is less impact to the joints. In fact, research shows that runners who substituted snowshoeing in the winter improved their running fitness over those who chose running as their primary activity.
Tobogganing is another healthy winter activity. Pulling a sled up hill will raise your heart rate and strengthen the upper and lower body. In fact, many of the top trainers are recommending sled pulling as an excellent cardiovascular workout. Instead of pulling a sled indoors, take it back to its origin and see amazing results. Plus you get the exhilaration of sliding downhill at rapid speeds.
Decreased motivation and feelings of sadness are common in the winter. Getting outdoors and catching even an hour of daylight can raise the spirits. Physical exercise stimulates the release of endorphins that gives you an overall feeling of well-being.
Remember when your parents used to send you outdoors to get some “fresh air?” Well, there is something to be said about this wise tale. Getting outdoors in the fresh air is good for your respiratory system. Being locked indoors with re-circulated air can cause headaches and congestion. Stepping outside and going for a walk can relieve headaches and help you breathe more easily.

While there are many great ways to workout outdoors this winter, be sure to always stay safe. Here are some safety tips to keep in mind:
1. — Dress for the weather. Layer your clothing to accommodate for the changing environment from cold to hot as you work out.
2. — Wear reflective clothing and avoid black. With darkness in the morning and early evening protect yourself by being seen.
3. — Keep your feet, hands and head warm, as this is where you lose the most heat. Cover up with appropriate winter gear.
4. — Wear shoes with good traction to avoid slipping.
5. — Find a workout buddy or let someone know you are going outdoors. You never know what can happen and you want to be sure someone knows where you are in case of an emergency.
6. — Carry a cellphone and don’t go out alone in the wilderness. Always check in with the park warden.
7. — Bring water and snacks. Even though you may not feel like you are sweating, you are still expending energy and dehydrating from exercise.
Change your perspective and get excited this winter about fitness. Winter activities are exhilarating and good for your health. Embrace the season and wrap up your winter fitness activity with a cup of dark chocolate milk.
