Blueberry Consumption Linked to Mood Improvements in Older Adults, Study Finds

A recent small-scale study examined the impact of daily blueberry consumption on mood among older adults. Over a three‑month period, participants who ate blueberries reported greater reductions in depressive symptoms compared with a placebo group. Researchers also observed changes in gut microbial enzymes, pointing to a potential gut‑brain link. However, the mood benefits did not reach statistical significance relative to placebo, underscoring the need for larger, more definitive trials. The study suggests that blueberries may influence mental well‑being through gut microbiota, but further research is required to confirm these effects.
