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.
Midlife Vitamin D Deficiency Tied to Early Alzheimer‑Like Tau Build‑Up in Large Framingham Study
Researchers analyzing 793 adults from the Framingham Heart Study found that lower vitamin D levels measured at an average age of 39 were associated with greater tau protein deposits on brain scans 16 years later. The observational finding highlights a potentially modifiable risk factor for preclinical Alzheimer’s disease, prompting calls for earlier screening and supplementation.
Metabolism, Not Plaques, Drives Early Alzheimer’s Decline
As a medical school professor, I now believe the biggest mistake in Alzheimer's research was ignoring metabolism. A comprehensive Frontiers in Neurology review makes the case clear: mitochondrial dysfunction and metabolic failure happen YEARS before amyloid plaques or memory loss. The evidence...
