Could What You Eat Ease Perimenopausal Anxiety, via the Gut?

This systematic review asks a genuinely useful question: could dietary changes that support the gut microbiome help with the heightened anxiety many women notice during perimenopause? The authors trace how declining, fluctuating oestrogen during this transition depletes beneficial bacteria such as Lactobacillus and Bifidobacterium, reduces short-chain fatty acid production, and is linked to a more permeable gut lining, immune activation and a dysregulated stress-hormone system — all plausible routes to anxiety symptoms. Mediterranean-style eating, fibre- and polyphenol-rich foods, fermented foods, and specific probiotic strains all showed promise in modulating these pathways. The honest caveat, stated clearly by the authors themselves, is that trials designed specifically for perimenopausal women remain scarce, so this is biological plausibility rather than proven treatment. It's a hopeful, low-risk starting point for anyone whose anxiety seems to have crept in alongside other perimenopausal changes — not a replacement for professional support, but a reminder that nutrition is a lever worth considering.
