Restriction of Meat, Fish, and Poultry in Omnivores Improves Mood
In a recent cross-sectional study involving 39 omnivores, restricting intakes of meat, fish, and poultry were found to be associated with improvements in mood. Subjects were randomly assigned to one of three groups: 1) consuming meat, fish, and poultry daily; 2) consuming fish 3-4 times/week, avoiding meat and poultry; 3) vegetarian group, avoiding meat, fish, and poultry). Subjects in the vegetarian group were found to have reduced consumption of arachidonic acid (AA), EPA, and DHA, while the fish group was found to increase DHA and EPA intakes. In the 2 week intervention, improvements in mood scores were found among subjects in the vegetarian group, not in the other two groups. The authors state, "Restricting meat, fish, and poultry improved some domains of short-term mood state in modern omnivores."
