A diet high in healthy, nutritious carbohydrates can result in a lower body mass index (BMI), according to a study appearing in the American Journal of Clinical Nutrition.

The study found that diets rich in fresh fruit, pasta, and rice and lower in meat were associated with lower BMI. These diets also resulted in more favorable micronutrient intakes and lower caloric intakes.  Increased consumption of carbohydrates, dietary fiber, and magnesium were also associated with lower BMI in both sexes.

The study examined the effect of energy, food, and nutrient intakes on BMI among 1794 US participants of the International Study of Macro-/Micronutrients and Blood Pressure (INTERMAP).  INTERMAP is an international cross-sectional study of dietary factors and blood pressure in men and women ranging in age from 40 to 59.
