One Diet Does Not Fit All

From eNewsletter 7/8

DID YOU KNOW that mitochondria, often called the cell's powerhouses, play a central role in aging? Along with coenzyme Q10, researchers have now identified phosphatidylcholine as an important contributor.

Findings from Nature Communications show that lower levels of phosphatidylcholine reduce the flexibility of mitochondria, accelerating age-related deterioration.

The researchers also found that supplying phosphatidylcholine through diet helped restore mitochondrial function in aging organisms. Phosphatidylcholine supplementation remained effective even when introduced during middle or advanced age.

Which Heart Scan Should You Get?

From eNewsletter 7/6/2026

DID YOU KNOW that a massive international study could upend 40 years of heart attack treatment? Researchers publishing in New England Journal of Medicine and European Heart Journal found that beta blockers, routinely prescribed after uncomplicated heart attacks, offered no real benefit for patients whose heart function remained normal, despite being given to millions worldwide.

Even more surprising, women taking the drugs faced a higher risk of death, repeat heart attack, or hospitalization for heart failure compared to women who didn’t receive them.

Best Supporting Role for Wellbeing

From eNewsletter 7/1/2026

DID YOU KNOW that worrying about getting older, especially fearing future health problems, may actually speed up aging at the cellular level, according to new research from Psychoneuroendocrinology?

In a study of more than 700 women, those who felt more anxious about aging showed signs of faster biological aging in their blood, measured using cutting-edge “epigenetic clocks.” One measured the speed of biological aging (DunedinPACE), while the other estimated accumulated biological damage over time (GrimAge2). Fears about declining health had the strongest link.

The findings underscore once again how closely mental and physical health are connected across the lifespan.
