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.

Meds and Your Microbiome

From eNewsletter 6/29/2026

DID YOU KNOW that medication can leave a lasting, negative impression on your gastrointestinal ecosystem?

In one study from Nature Medicine, compared with people who have not received antibiotics, those treated with certain antibiotics show differences in their gut microbiome up to 8 years later, with the strongest differences associated with clindamycin, fluoroquinolones, and flucloxacillin. Evidence of absent beneficial microflora species in the gut years later was observed even after just one course of antibiotics. The authors did not mention how probiotic supplementation can repopulate lost species, but this would be how to do it.

Another study from mSystems found that changes persisted long after people stopped taking medications that were not limited to antibiotics. Antidepressants, beta-blockers, proton pump inhibitors, and benzodiazepines also left distinct microbial fingerprints, with benzos having as strong of an effect as antibiotics.

Vitamin C and Cancer

From eNewsletter 6/24/2026

DID YOU KNOW that a brief, intense workout may do more than boost fitness? It can help fight cancer.

According to a study from International Journal of Cancer, just 10 minutes of hard exercise releases molecules into the bloodstream that switch on DNA repair and shut down cancer growth signals. When these molecules were applied to bowel cancer cells, hundreds of cancer-related genes changed activity. The discovery helps explain how exercise lowers cancer risk.
