The pursuit of longevity through health optimization often leads to a plethora of conflicting trends, tips, and advice. For instance, Bryan Johnson, the leader of the Don’t Die regime, follows a strict regimen that includes numerous supplements but avoids candy and other unhealthy foods.
When it comes to diet and longevity, the information available can be just as confusing. Some advocate for high meat consumption, while others caution against it. Walter Willett, a nutrition researcher from Harvard T.H. Chan School of Public Health, even likened meat to radiation, stating that the safe level is unknown.
Walter Longo, director of the Longevity Institute at the University of Southern California, provides a clear-cut recommendation: a mostly vegan diet with low protein intake and a fasting diet confined to meals between 8 a.m. and 8 p.m.
However, Dr. Frank Hu, a Harvard professor of nutrition and epidemiology, emphasizes that there is no one-size-fits-all diet for everyone. He suggests that various dietary patterns can help prevent chronic diseases and improve longevity.
The key principle across all diets, if one aims to live a long life mostly free of disease, is the elimination of ultraprocessed foods. These include packaged snacks, cookies, fast-food burgers, and soda, which are high in sugar, sodium, and unhealthy fats.
One diet that is commonly promoted for preventing chronic disease and preserving cardiac health is the Mediterranean Diet. This diet encourages limiting dairy products, increasing fish and omega-3 intake, and paying attention to the types of fats and carbs consumed, rather than eliminating them entirely. Extra virgin olive oil is a significant part of this diet, as it not only lowers cholesterol but may also prevent other chronic diseases like dementia or Alzheimer’s.
