Gut bacteria, fibre and hormones: what 2026's precision-nutrition research means for women over 40

Anxiety and brain fog, not hot flashes, are now women's top menopause complaint

Type 2 diabetes is rising twice as fast in women under 40 — and care hasn't caught up

HRT prescriptions have more than doubled since 2018 — and patches are now running short
