A new large-scale study suggests that diet plays a key role in how well people age. Researchers tracked individuals’ eating habits and health from midlife to around age 70. Their findings highlight the benefits of a mostly plant-based diet while avoiding red meat and ultra-processed foods.
What the Study Revealed
The study, published in Nature Medicine, followed about 105,000 people in the United States for up to 30 years. Researchers analyzed the effects of eight different diets, including the Mediterranean diet—rich in olive oil, fish, and nuts—and the DASH diet, which helps control blood pressure by limiting sodium intake.
The healthiest individuals at age 70 consumed plenty of fruits, vegetables, whole grains, nuts, beans, and unsaturated fats. They also ate moderate amounts of low-fat dairy and other animal-based foods.
Foods to Avoid for Better Health
Participants with the best health outcomes minimized their intake of red and processed meats, sugary drinks, trans fats found in fried foods, and high-sodium products.
“There may not be one perfect diet, but multiple eating patterns can promote good health,” said Marta Guasch-Ferré, the study’s senior author and an associate professor at the University of Copenhagen.
Most People Are Not Aging Healthily
Despite the benefits of a balanced diet, fewer than 10% of study participants reached 70 without major chronic conditions. To be classified as aging well, individuals needed to maintain strong mental function, good physical health, and avoid serious diseases.
Guasch-Ferré emphasized that the study offers a more complete perspective on healthy aging. Instead of focusing solely on lifespan, it considers overall quality of life.
“Do we just want to live longer, or do we want to live better?” she asked.
