Story summary

University College Cork researchers identified metabolic pathways by which exercise mitigates behavioral effects of a Western-style cafeteria diet.
The study, published in Brain Medicine, shows running improved depression-like behaviors in male rats on high-fat, high-sugar diets.
It also found exercise altered gut metabolites linked to mood regulation, suggesting therapeutic targets for mood disorders.
However, the cafeteria diet inhibited neurogenesis, indicating long-term mental health may require dietary improvements alongside physical activity.
