Bones, Bacteria, and Bladders: What You Eat Actually Matters

Three new studies look at what women are actually eating — and what it's doing to their bones, their vaginal microbiome, and their bladder. Nykki breaks down what the research says and what, if anything, is worth changing this weekend.
Key Takeaways:
• Many women at risk for bone thinning — including those on hormone-blocking therapy for breast cancer — are getting significantly less calcium from food than they need, often without realizing it.
• A small randomized controlled trial found that a protein found in cow's milk, called lactoferrin, shifted the vaginal microbiome in postmenopausal women toward a healthier bacterial balance — but the study was small and short, so it's early days.
• Women with bladder leaks tend to drink less fluid overall, which can actually make urgency and irritation worse, not better — the "drink less to leak less" instinct often backfires.
• All three studies are preliminary or single-center, which means they're interesting starting points, not final answers. Worth knowing about; not worth overhauling your life over yet.
• Calcium from food is still better absorbed than from supplements for most people — and most women over 45 aren't hitting the daily target from diet alone.
