Severely obese women may be healthier than their male counterparts. New research shows that severely obese men were less physically fit, more prone to diabetes and more carbohydrate-intolerant than women. The findings could eventually influence how doctors select candidates for weight-loss surgery. "It's quite surprising that men were doing so much worse than women," says lead scientist Emile Dubois, a pulmonologist at the Hospital Reinier de Graaf Groep in the Netherlands.

Kudzu, the wild vine that has overtaken almost 10 million acres in the southeastern United States, may be more nutrient than nuisance. Previous studies have suggested a chemical in the vine may help alcoholics curb their addiction. Now a study, also in rats, shows kudzu can help regulate blood pressure, glucose metabolism and cholesterol levels. Kudzu root, which is called Radix puerariae, contains polyphenols, substances that are known to have a range of positive health effects.

A widely used antioxidant supplement can reduce some of the symptoms of autism in children, a pilot study has found. The supplement -- N-acetylcysteine, or NAC -- lowered irritability in the children and reduced repetitive behaviors, researchers from the Stanford University School of Medicine reported in the journal Biological Psychiatry. The team cautioned, however, that only 31 children were enrolled and that larger studies are needed to confirm the potential benefit. Currently, irritability, mood swings and depression in autistic children are treated with antipsychotic drugs.

Dr. Robert Atkins shook up the nutrition establishment in 1972 when he published "Dr. Atkins' Diet Revolution. " In that book and others that followed, he asserted that dieters could lose weight eating bacon, eggs, steak and rich sauces. His low-carb diet has remained controversial even as its popularity has waxed and waned through the years. Atkins died in 2003, and three other doctors have taken up his cause with an updated Atkins diet book, published last March. More than 300,000 copies of their book, "The New Atkins for a New You," are in print, according to publisher Fireside.

Americans tend to like their fats saturated, their grains processed, their protein grown on legs and their sugar added anywhere their sweet tooth decides it would like some. As for fiber, they're all for it - in, say, their French fries or the pickles on their burger. In a related development, nutrition experts tend to be bummed out by the typical American diet. In fact, many wish we'd trade it in for a diet that's pretty much the opposite, namely, the Mediterranean diet, which favors monounsaturated fat, whole (unprocessed)

Scientists are changing their minds about the best way to monitor body fat. Body mass index, or BMI -- long considered the gold standard for evaluating an increased risk of health problems due to weight -- is far from a perfect measure, says Dr. Arya M. Sharma, an obesity researcher at McMaster University in Hamilton, Ontario, Canada. The BMI doesn't take into account the amount of muscle a person has, and is less accurate in older people, who lose muscle and bone and gain fat with age.

That cup of joe may be doing more than keeping you awake ÃÂÃÂ it also may be reducing your risk of developing Type 2 diabetes. Coffee That's the conclusion of a recent Japanese study involving a strain of mice that are known to become diabetic. Studies of people have found a correlation between coffee consumption and a reduced risk of diabetes. To find out if there was a direct link between coffee and diabetes, the Japanese researchers let mice drink diluted black coffee instead of water.

Some popular diets advise against late-night snacking or even eating after 6 p.m. Now, there's some research to confirm that when you eat could matter as well as what you eat if you're trying to shed pounds. A study in Spain followed 420 men and women on a diet for 20 weeks. They were grouped into early eaters -- those who had their main meal before 3 p.m. - and late eaters - those who had it after. (The participants followed the Mediterranean diet, in which the main meal was lunch.)
