Effects of eating behavior on mood: a review of the literature.

The literature focusing on the use of food as a regulator of a negative mood state is reviewed. This literature reveals that individuals experiencing a negative mood state arising from disorders ranging from tobacco withdrawal to premenstrual symptoms make use of carbohydrate ingestion, especially simple carbohydrates, to provide a temporary lifting of mood. However, other evidence suggests that some individuals may obtain a more permanent control of their negative mood stay by eliminating simple carbohydrates from their diet. While the literature is consistent in demonstrating that carbohydrate consumption can alter a negative mood state, the underlying mechanism mediating this relationship is unknown.
