A Harvard-led study published in Nature Medicine and covered by EatingWell tracked more than 105,000 adults across 30 years and asked a question most research avoids: not how long people live, but how well. Healthy aging was defined as reaching 70 free of 11 major chronic diseases including cancer, diabetes, heart attack, and stroke with cognitive function, physical capacity, and mental health intact. Only 9.3% of participants qualified. Among the eight dietary patterns examined, those who most closely followed the Alternative Healthy Eating Index (AHEI) a pattern heavy in vegetables, whole grains, nuts, legumes, and healthy fats, and low in processed meat and sugar sweetened beverages had 86% greater odds of healthy aging at 70, and more than double the odds by 75. Here's what people are reacting to: after 30 years and 105,000 people, only one in ten made it to 70 genuinely healthy, and the dietary gap between the top and bottom fifth tells you exactly why.
TIME published a cortisol myth-busting piece on April 23 as searches for the term "cortisol" have nearly doubled since January and hit record highs for three consecutive months. The piece makes a clinically important point that most wellness content gets backwards: burnout is not associated with chronically high cortisol, it is associated with a flattened cortisol rhythm and sometimes low cortisol, a state the body reaches after prolonged stress has worn the system down. The hormone that everyone is trying to lower may already be too low by the time they notice something is wrong. Here's what people are reacting to: everything they've been told about cortisol and stress is probably backwards.
If you were to choose only three lifestyle factors that most profoundly shape how you age, they would be stress, sleep, and strength. Together, they form the biological triangle that determines your metabolic health, hormonal balance, inflammation levels, body composition, cognitive performance, and daily energy. These three factors interact so deeply that improving one nearly always improves the others. When optimized together, they can slow or even reverse many of the early signs of aging.
A study published this week out of the USC Leonard Davis School of Gerontology found that adults over 70 who received the shingles vaccine showed measurably slower biological aging across multiple domains, including lower chronic inflammation, slower epigenetic aging, and better composite biological age scores, compared to unvaccinated peers. The sample was nearly 4,000 people drawn from a nationally representative U.S. cohort, and the effects held even after controlling for income, education, and underlying health status. The results were most pronounced within three years of vaccination, but slower aging persisted beyond that window. Here's what people are reacting to: a routine shot your doctor has been recommending for years appears to do something that no supplement company has figured out how to bottle.
Here’s what people are reacting to: a wave of new coverage highlighting VO₂ max as one of the strongest predictors of longevity, with cardiologists calling it a “vital sign” that deserves more attention than cholesterol alone. The takeaway circulating online is simple: if you want to live longer, improve your aerobic fitness.
As our ResetRx advisor, Dr. Jacob Kelly, explains:
“Cardiovascular fitness predicts longevity and how long someone will live with better accuracy than almost any other metric. The VO₂ max is like a credit score for your heart and mitochondria.” Read more on Dr. Kelly's substack
