Junk food can harm memory in a week - study found

Forget the damage to your waistline - over-indulging at Christmas could take its toll on your brain cells, too. Eating a diet loaded with saturated fat and sugar may have an immediate effect on the brain's cognitive ability and cause memory loss , a University of New South Wales (Australia) study has found. ''We know obesity causes inflammation in the body, but we didn't realize until recently that it causes changes in the brain,'' said Margaret Morris, the head of pharmacology at the University of NSW. The team placed rats on a diet high in sugar and fat and compared their performance with rodents on a healthy diet. Researchers were able to ascertain that rats fed a diet high in fat and sugar had impaired memory after just a week . Interestingly, the results were similarly poor for the rats fed a healthy diet and given access to sugar water to drink. The cognitive impairment related to place recognition , with the animals showing poorer ability to notice wh...

WANT TO BREAK JUNK FOOD ADDICTION? BE ACTIVE - recent study found

If you just overindulged in high calorie foods during the holidays, there is an unexpected way to defend yourself, at least next time: resisting the "sins" of gluttony through physical activity. It is what researchers at the Department of Psychiatry at Harvard Medical School, Boston, found in a study published in Neuroreport last 4th of December. In this search scholars observed that who did regular exercise had areas of the brain -the orbitofrontal cortex and the insula- less active at the sight of highly caloric food pictures . This means that the brain of active people tends to be less "reactive" in front of "tempting foods". Therefore exercise not only burns the extra calories, but can reduce our preferences for unhealthy high-calorie foods. But there is some more evidence: another recent research published in the American Journal of Clinical Nutrition studied the effects of high-intensity exercise on neural responses to images of food. Fifteen lean...

THE TOP 10 FOODS THAT HELP BUST HOLIDAY STRESS

To overcome the winter and the holiday season without stress and without eating excessively , some foods can be helpful, in particular the ten foods listed by nutritionists of Washington University : these foods are a good aid for your health because they help to rest better and fight anxiety that causes eating too much and bad, especially when it's time to celebrate. “ Some foods appear to soothe us; others fight the inflammation that comes with stress ,” said Connie Diekman, director of university nutrition at Washington University in St. Louis. “Stress eating, however, can be a problem this time of year. During stressful periods, there is the mental response of ‘I need to do something.’ And that ‘something,’ for some of us, is eating as much as we can as fast as we can . We have learned. ‘If I eat, I can avoid’ or ‘I can energize.’ The problem is, of course, once people do it, they realize it didn’t help.” Diekman encourages to eat a healthy meal every three to four hours...

Why exercising WON’T curb holiday weight gain

People put on an average 2lb over the festive period and most never lose it again , according to a recent study published in the European Journal of Clinical Nutrition . This means that over a period of 10 years, the average person gains 20lbs. Researchers at Texas Tech University, also found exercise does not help people lose the weight they put on during the holidays. The team studied 48 men and 100 women between the ages of 18 and 65; half of the volunteers said they were serious exercisers, while the other half admitted to not taking any exercise. The researchers found that the weight gained during the holidays very often won't be lost; they also found that the people who were overweight at the beginning of the research period put on the most weight - and saw the greatest increase in body fat percentage. Furthermore they found that how much exercise the person did had no impact on the amount of weight they gained . The team admit they aren't sure why this was - and accep...

DO YOU WANT TO CONTROL YOUR WEIGHT? DON'T COUNT THE CALORIES BUT CHECK THE QUALITY OF THE FOOD YOU EAT - study shows

Paying attention to calories is not the only precaution necessary to be able to lose weight ; in fact , according to a recent research , the kind of foods that you choose to eat can be even more important. The scholars showed that the index of the quality of the diet (IQD) is the parameter that makes the difference between being obese or lean, regardless of the number of calories consumed. It's like saying: no matter how much you eat, what you eat matters . The news comes from the 7th Regional Congress of the Italian Society of Obesity ( Sio ) which took place at the University La Sapienza in Rome last 14th of December. The study found that introducing 2,000 calories a day a person may be obese, but also lean . It's definitely a revolutionary approach because so far most weight-loss diets are always counting calories. It is widespread a food culture that puts a lot of attention to the calorie content of a food: just think that by now there are few packages of food fo...

BROCCOLI: A HEALTHY FOOD YOU'RE PROBABLY EATING WRONG

Broccoli is one of the healthiest vegetables out there, containing many essential vitamins and minerals and significantly reducing your risk of developing cancers . New research shows that people who don't cook it in the right way could be wasting their time. Scientists found broccoli loses its cancer-fighting properties when it is boiled or microwaved. The researchers, who presented their findings at the American Institute for Cancer Research Annual Research Conference, found the best way to cook the vegetable is to steam it for up to five minutes . They say steaming it until it turns a bright green colour can enhance its cancer-fighting compounds. Researchers have long been writing about the health benefits of broccoli, particularly one of its ingredients - sulforphane, which is thought to have anti-inflammatory and anti-cancer qualities. The authors warn that depending on broccoli powder supplements alone will not have anywhere near the same benefits, and neither will overc...

Chemical in fries prompts FDA advice

Crispy french fries and crunchy potato chips were never health foods, what with all the calories, fat and salt. But consumers just got a reminder that there's one more thing to worry about when they indulge in such foods: a chemical called acrylamide that might cause cancer. In a consumer update posted to its website, the FDA details the reasons to consider cutting back on acrylamide, a chemical that forms naturally in plant-based foods when they are cooked at high temperatures for a long time. In other words, it's usually found in fried foods , like french fries. It's produced from a chemical reaction from the sugars and an amino acid called asparagine , which is found in many grains and vegetables. (And potatoes have a particularly high amount of it, further exacerbating the french fry problem.) Animal studies have shown that high levels of acrylamide are linked to an increased risk of cancer , although long-term studies have not yet been done in humans. Bot...

BENEFITS OF BROWN RICE

Rice, especially brown rice, is a major food staple consumed by over half the world's population every day. The difference between brown rice and white rice is not just color: the process that produces brown rice removes only the outermost layer, the hull, of the rice kernel and is the least damaging to its nutritional value. Indeed the more processed white rice is simply a refined starch that is largely bereft of its original nutrients . Brown rice is not only fiber rich, but also protein-rich with only a small amount of fat. It provides vitamin E and B vitamins and minerals such as iron, calcium, magnesium, phosphorus, potassium, sodium and zinc. By eating brown rice every day as part of a well-balanced diet, you can help ensure your body's good health. Nutritional profile A team of researchers at Cornell University, including WGC Scientific Advisor Rui Hai Liu shows that whole grains, such as rice, contain many powerful phytonutrients whose activity has gone unrecognized...

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 t...

Sweet News: Dark Chocolate May Prevent Obesity And Diabetes

If you’re going to munch on chocolate, choose dark chocolate. It’s something that has gained popularity as growing research points out the various health benefits of eating dark chocolate in moderation. Antioxidants and flavonoids make it so good Studies have shown that dark chocolate, which is rich in flavanols — a type of healthy antioxidant — can improve your cardiovascular system. Chocolate is also filled with other types of antioxidants and flavonoids , the latter of which are found in various fruits and vegetables. Flavanols are the main type of flavonoid in cocoa, and have been shown to improve vascular health by lowering blood pressure, improving blood flow to the brain and heart, as well as boosting the clotting properties of blood platelets. Not all chocolate is created equal In fact, that strong bitter taste in really dark chocolate comes from flavanols. That’s why processed chocolate — which goes through plenty of steps to reduce that bitter taste — is sweete...

SOUPS THAT CAN HELP WEIGHT LOSS IMPROVING SATIETY & BOOSTING METABOLISM

Soup is often listed as one of the foods it’s a good idea to add to your diet if you want to lose weight. But with so many different varieties to choose from, ranging from thin consommés to rich, creamy soups – not to mention myriad slimming soups from cabbage to crazy – many of us are left wondering what the best soup for weight loss is. Soup and weight loss: the scientific evidence Increasingly, research has revealed that consuming soup improves satiety (the feeling of fullness at the end of a meal) so that we eat less and take in fewer calories which is great for weight loss. Eating soup appears to be far more effective – and a whole lot tastier – than drinking a glass of water with a meal to help fill us up, the latter of which is often a top diet tip. In a study from Pennsylvania State University, researchers asked women to eat chicken casserole, chicken casserole with a glass of water, or chicken casserole with the same amount of water added to make a sou...
