Scientists now saying carbs, not fat, are to blame for America's ills - latimes.com Most people can count calories. Many have a clue about where fat lurks in their diets. However, fewer give carbohydrates much thought, or know why they should. But a growing number of top nutritional scientists blame excessive carbohydrates — not fat — for America's ills. They say cutting carbohydrates is the key to reversing obesity, heart disease, Type 2 diabetes and hypertension. "Fat is not the problem," says Dr. Walter Willett, chairman of the department of nutrition at the Harvard School of Public Health.

It's a confusing message. For years we've been fed the line that eating fat would make us fat and lead to chronic illnesses. "Dietary fat used t...

European Journal of Clinical Nutrition - Abstract of article: Gastrointestinal transit, post-prandial lipaemia and satiety following 3 days high-fat diet in men Background/Objectives: High-fat (HF) diets of 2 weeks have been shown to accelerate gastric emptying (GE). To date, no studies have shown any alteration in GE following shorter HF diets. The aim of this study was to assess if an HF, high-energy diet of 3 days can adapt gastrointestinal (GI) transit, blood lipids and satiety. Subjects/Methods: Eleven male volunteers participated in a study consisting of three, 3-day interventions each separated by a test day. During the first intervention, volunteers recorded their diet. In the second and third interventions, volunteers repeated their food diary plus either a low-fat yogurt or HF yogurt supplement in randomized order. Test days involved measurement of GE using the 13C octanoic-acid breath-test, mouth-to-caecum transit time (MCTT) using the inulin H2 breath test and satie...
