The very latest health and fitness tips
Limiting carb intake has become fashionable, but a new paper from the Atherosclerosis Risk in Communities Study says diets that are low (under 40%) or very high (over 50-55%) in carbs were associated with the highest risk of mortality. The review looked at studies involving diet records from 432,000 people from over 20 countries.
Using smaller plates is a well-known ploy to try to trick the brain into thinking your portion size is larger. However, researchers at the Ben-Gurion University of the Negev (BGU) in Israel have cast doubt on that theory, by discovering that a group who hadn’t eaten for three hours were better at identifying correct proportions in portions of pizza than those who had just eaten.
Varied diet best?
Get a varied diet, says traditional advice – but an article published in the American Heart Association journal Circulation says there’s no evidence that a diverse diet encourages healthy weight or optimal eating, and that it could lead to an increased calorie intake overall. The authors recommend eating low-fat dairy products, nontropical vegetable oils, nuts, poultry and fish.
Salt in the wound?
Salt is often presented as public enemy No.1, but one group of scientists believes that consuming sodium doesn’t normally lead to health problems unless your intake is more 5g per day – and fewer than 5% of people in developed countries tend to go above that level. The study, which involved 94,000 people over eight years, cast doubt on World Health Organisation recommendations of less than 2g of sodium per day.
