A national health study has found that diets low in carbohydrates, complimented by moderate amounts of fat, are better for you than the low-fat diet that doctors and government authorities have recommended for decades.

Individuals in the low-carb group saw inflammation and triglyceride metrics plunge while those of the low-fat dieters remained constant.
