Gut microbes may dictate cellular aging, new review suggests
A Frontiers in Aging review introduces the microbiome‑gerogene axis, proposing that gut microbes act as upstream regulators of cellular aging networks. Age‑related dysbiosis reduces key metabolites, leading to leaky gut, chronic inflammation and epigenetic drift that accelerate organ decline. The authors highlight precision interventions such as ellagitannin‑derived urolithin A and fermentable fibers to restore microbial balance.

Moderate Exercise Lowers Cortisol, Boosts Metabolic Health
This is important. He's almost entirely wrong, but not quite. Cortisol release is intensity-dependent. While work >~60% VO2max increases cortisol, work <50-60% VO2max decreases cortisol below baseline levels. That is, it's a de-stressor that stabilizes your metabolism. In other words, the metabolic health of...
