Fish-Eaters and Vegetarians Show Slower Biological Aging Than Regular Meat-Eaters
Among over 400,000 UK adults, people who ate fish but little meat aged the slowest biologically. Vegetarians came in a close second. Regular meat-eaters aged fastest by two different biological age measures. These patterns held up over time too. People who stuck with low-meat, fish-based, or vegetarian diets saw their biological aging slow down compared to consistent meat-eaters during follow-up.
Kernaussage
This study suggests reducing meat and including fish may be linked to slower biological aging.

Mediterrane und MIND-Diät mit niedrigerem Demenzrisiko bei Koreanern verbunden
In einer 20-jährigen Studie mit über 5.000 koreanischen Erwachsenen hatten diejenigen, die sich am stärksten an die Mediterrane, MIND- oder Korean Healthy Eating Diät hielten, etwa 20% geringere Chancen, hohe Demenzrisiko-Werte zu entwickeln. Wer am meisten entzündungsfördernde Lebensmittel aß, sah sein Risiko steigen. Die Erkenntnisse passen zu dem, was wir über gehirnfreundliche Ernährung vermuten, sind aber der erste solide Beleg in einer koreanischen Bevölkerung.
Tracking Your 'Biological Age' Over Time May Predict Death Risk Better Than a Single Snapshot
In over 90,000 Dutch adults followed for nearly 14 years, people whose biological age ran ahead of their calendar age had a higher risk of dying. More importantly, among 25,000 people measured twice, those whose biological age sped up over time faced even greater risk. People stuck in a pattern of accelerated aging had a 39% higher mortality risk compared to those aging at a normal pace. The results suggest that checking biological age once might not be enough.
Faster Biological Aging Linked to Worsening Brain Small Vessel Disease
People who age faster biologically (based on blood biomarkers) appear more likely to develop worsening brain small vessel disease. In roughly 3,000 middle-aged adults followed for about five years, those with higher biological age scores had more new tiny brain lesions like lacunes and microbleeds. This held true even after accounting for actual calendar age. The finding suggests that biological aging clocks could help flag people at risk for this common precursor to dementia and stroke.
