He is recognized for his best-selling books How Not to Die and How Not to Diet, both of which focus on how diet can prevent and reverse disease. Greger's work has been influential in shaping public understanding of the relationship between diet and health.

In exploring the biology of aging, researchers have identified key mechanisms like oxidative stress, autophagy, telomere shortening, and cellular senescence, each playing a pivotal role in the aging process. Oxidative stress damages cells over time, while autophagy, the body’s natural recycling system, declines with age, leading to protein accumulation and disease. Telomeres, the protective caps on chromosomes, erode with each cell division, contributing to genetic instability, while senescent cells, though initially protective, accumulate and release harmful inflammatory compounds. Diet emerges as a powerful tool to counteract these effects, with plant-based foods, nuts, and antioxidant-rich fruits and vegetables supporting longevity. Hydration, teas, and moderate coffee consumption further enhance health, while alcohol and processed drinks are best avoided. Lifestyle factors like regular exercise, balanced sleep, and stress management complement dietary strategies, collectively fostering cellular health and extending life. This intricate interplay of biological and lifestyle factors sets the stage for deeper insights into interventions that may slow aging and enhance well-being.
