Your Mouth Reveals Your True Biological Age
Your Mouth Knows How Old You Really Are As a medical school professor, I've taught that the mouth is a window into systemic health. A new Nature Communications study just made that literal. Researchers built an "Oral Microbiome Aging" score from 64 bacterial genera in ~6,000 people. A faster-aging oral microbiome independently predicted: (1/4)

Alzheimer’s Prevention Begins Decades Early with Hormones, Sleep, Muscle
Alzheimer’s doesn’t start with memory loss. It starts decades earlier: through hormonal decline, poor sleep, metabolic dysfunction, inflammation, and loss of muscle. For women, menopause is a major neurological transition, not just a hormonal one. Protecting estrogen balance, preserving muscle, prioritizing deep sleep,...
