Forever chemicals may age men faster in their 50s, new research suggests

A Frontiers in Aging study links PFAS “forever chemicals”—present in the blood of about 98% of Americans—to accelerated epigenetic aging, with the strongest effects in men aged 50–65. Using NHANES data from 1999–2000 and 11 PFAS measured in blood, researchers found sex-specific associations and smaller signals in women. Experts caution the findings show associations, not causation, and regulatory bodies describe them as exploratory. Practical reductions in exposure (such as certified water filters and limiting contact with stain- or grease-resistant materials) are considered reasonable, though complete avoidance is unlikely; broader regulatory actions may be needed to curb PFAS exposure.

Shingles Shot May Slow the Body's Aging Clock, USC Study Finds

A USC Leonard Davis School of Gerontology study analyzing the Health and Retirement Study (about 3,800 people aged 70+ in 2016) found that those who received the shingles vaccine had slower biological aging on several measures—lower inflammation and slower epigenetic and transcriptomic aging—than unvaccinated peers, suggesting vaccines may influence aging beyond preventing shingles, with effects lasting at least four years after vaccination; the results show an association, not causation.

No Children or 5+ Children Linked to Faster Aging in Finnish Study

A Finnish study of 14,836 women from the Finnish Twin Cohort finds that those who had five or more children, or none at all, aged biologically faster and had shorter lifespans than those with one to four children, suggesting a U‑shaped link between reproduction and aging. Researchers caution that the historical, Finland-specific cohort (born 1880–1957) may limit applicability to today’s contexts, and that social factors and health histories likely influence aging alongside biology.

Shingles vaccine linked to slower aging markers in seniors

A USC-led observational study using data from the Health and Retirement Study found that adults aged 70+ who received the shingles vaccine showed signs of slower biological aging, including reduced inflammation, slower epigenetic aging, and stronger immunity, with the strongest effects within three years post-vaccination; however, the cross-sectional design means causality can’t be established and further research is needed.

Scientists Discover Why Aging Gut Genes Go Silent

Scientists discovered a specific epigenetic drift called ACCA that accumulates in aging gut stem cells, leading to gene silencing linked to inflammation and cancer risk. This process is influenced by iron metabolism and inflammation but can potentially be slowed or reversed by restoring iron levels or activating Wnt signaling, offering new insights into intestinal aging and cancer prevention.

ADHD and Nutrition: A Health Brief

A review of 37 studies suggests that choosing plant-based foods over animal-based ones, particularly red and processed meat, can reduce the risk of heart attack, stroke, Type 2 diabetes, insulin resistance, non-alcoholic fatty liver disease, and all-cause mortality. Another study found that a lack of nurturing in childhood is linked to accelerated biological aging in older adults. Additionally, a national birth cohort study in Israel revealed that adults diagnosed with ADHD in adulthood were nearly three times more likely to develop dementia later in life.
