LampHill Letter: September 2026

This month's articles run from the molecular machinery of aging itself to the specific nutrients most people assume they understand. Two pieces challenge confident received wisdom: one on LDL, one on omega-3. The rest build the underlying framework.

This month's reading

Longevity. Aging breaks down into at least 12 distinct, measurable processes, each mechanistically linked, and each addressable. Hallmarks of aging

Cardiovascular. The apoB model is among medicine's best-tested ideas, so what happens when a specific population appears to contradict it? Is high LDL always dangerous, the Lean Mass Hyper-Responder challenge

Brain. The clinical evidence for omega-3 and brain health turns out to be more specific, and more modest, than the packaging implies. Omega-3 and brain performance, memory, executive function, null in global cognition

Supplements. Roughly half the population falls below the recommended intake for a mineral involved in over 300 enzymatic reactions. Magnesium

Biomarkers. Your DNA carries chemical tags at hundreds of sites that can be read as a biological age, which may differ from your chronological one. Epigenetic clocks
