Cleaning up your carb act: Where to begin

Most Americans eat between 250 and 300 grams of carbohydrates a day, the equivalent of 1,000 to 1,200 calories. The Institute of Medicine, which sets dietary nutrient requirements, recommends 130 grams a day. Some, such as Dr. Frank Hu, professor of nutrition and epidemiology at the Harvard School of Public Health, say achieving that would be a big step in the right direction, but other low-carb advocates believe the number is too inflexible.
