Cutting Meat Out of Diet Improves Mood

Omnivores who cut all meat out of their diets experience mood improvements, according to a poster session presented this week at the annual American Public Health Association conference. Researchers at Arizona State University divided 39 omnivorous participants into three dietary groups: control (made no changes to diet), fish (consumed three to four servings of fish per week and no other meat), and vegetarian (consumed no meat and no eggs). The vegetarian group experienced mood improvements in both tension and confusion categories, while the meat-eating participants and fish eaters showed no significant changes in mood.
