Low-Carb Diets Better Than Low-Fat Diets at Preventin...(whole grains cereal fiber fruit and vege...),Health

For this study, Halton and his colleagues examined the association between low-carb diets and the risk of diabetes among 85,059 women participating in the Nurse's Health Study. The data included 20 years of follow-up.

Women were ranked according to what they ate. "We calculated a low-carbohydrate diet score based on the women's percent consumption of fat, protein and carbohydrate," Halton explained. "A higher score reflected a higher intake of fat and protein and a lower intake of carbohydrate. Therefore, the higher a woman's score, the more closely she followed a low carb-diet, and the lower her score, the more closely she followed a low-fat diet."

Women with a higher score did not have a heightened risk of diabetes. In fact, they seemed to have a small decreased risk when they derived their fat and protein from vegetable rather than animal sources.

Such a low-carb diet is similar to a healthy Atkins diet, meaning one which does not include large amounts of animal fat and animal protein, Halton said.

"When focusing on vegetable sources of fat and protein, this version of Atkins is similar to a low-glycemic Mediterranean diet," he said.

How easy will it be for people to follow such a diet?

"It's probably a very good thing to do . . . [but] people don't understand how to eat well. People don't know what simple and complex carbohydrates are and what it takes to have a good, balanced diet. People go to extremes," said Dr. Stuart Weiss, a clinical assistant professor of medicine at New York University School of Medicine in New York City. "In general, carbs should be limited just like saturated fat needs to be limited. . . If you eat too much of anything, you're bound to get into trouble."
