 A new study in JAMA Psychiatry suggests soft drink consumption may alter the gut microbiome in ways that raise the risk of depression—especially in women. Researchers found changes in key bacteria like Eggerthella helped mediate this link, pointing to the gut as a surprising middleman between sugar, microbes, and mood. The findings highlight diet as a powerful—and overlooked—lever in mental health.
