Avoid Meat, Improve Mood

Meat-free diets make people happy, according to researchers from the Department of Nutrition at Arizona State University. In a randomized controlled trial, scientists put adult omnivores on a meat-free diet for two weeks and measured changes in their mood. Thirty-nine participants were separated into three groups: one with no diet change, one that avoided meat and poultry but still ate fish, and one that did not consume any meat at all. The entirely vegetarian group showed significant mood improvement, while the group that still ate fish did not change. The results of this study were presented at the annual American Public Heath Association conference last week.
