High-Glycemic Index Diets May Up Depression Risk in Women

Eating a diet high in refined carbs appears to increase depression risk in postmenopausal women reports a new study published on the American Journal of Clinical Nutrition.

James E. Gangwisch, PhD, from Columbia University in New York City, and colleagues assessed the relations between dietary glycemic index, glycemic load and other carbohydrate measures with depression in postmenopausal women participating in the Women's Health Initiative Observational Study (87,618 women at baseline between 1994 and 1998 and 69,954 women at 3-year follow-up).

Higher dietary glycemic index was associated with increasing likelihood of incident depression. There were also increasing odds of incident depression with higher consumption of dietary added sugars.  There were significantly lower odds of incident depression associated with higher consumption of lactose, fiber, non juice fruit and vegetables, while nonwhole/refined-grain consumption was associated with increased odds of depression.
