A groundbreaking new study has revealed the key to aging well: eating mostly plant-based foods, while cutting back on red meat and ultra-processed options. This large-scale analysis tracked the health outcomes of approximately 105,000 people in the United States from midlife into their 70s, offering valuable insights into the dietary habits linked to physical and mental well-being in old age.
Published in Nature Medicine, the study examined eight different eating habits, including popular diets like the Mediterranean diet—rich in olive oil, fish, and nuts—and the DASH diet, which focuses on controlling sodium intake to manage blood pressure. The results were clear: the healthiest individuals, as they reached their 70s, enjoyed a diet abundant in fruits, vegetables, whole grains, legumes, nuts, and moderate animal-based foods, such as low-fat dairy.
What sets these individuals apart is their avoidance of ultra-processed foods, sugary drinks, red or processed meats, and trans fats commonly found in fried foods. As study author Marta Guasch-Ferré, an associate professor at the University of Copenhagen, explains, there is no one-size-fits-all diet for healthy aging. “It’s not about finding a miracle food, but rather, adopting dietary patterns that can enhance overall health.”
Despite the promising findings, the study highlights a sobering reality—fewer than 10% of people actually experience healthy aging. Healthy aging, as defined by the study, means reaching 70 without chronic diseases, maintaining strong cognitive function, and preserving physical and mental health. This broader approach to aging, which considers quality of life and not just longevity, is a critical shift in health research.
Though the study focused on the United States, Guasch-Ferré believes its findings are equally applicable to Europe. Despite acknowledging the role of factors like genetics, environment, and healthcare access, the research suggests that adjusting diet could be a powerful tool for improving health outcomes in old age.
While healthy aging is about more than just diet, Guasch-Ferré notes, “Every small improvement in dietary habits can make a significant difference.” The study’s findings may lead to updated dietary guidelines and encourage individuals to make more mindful food choices for long-term health benefits.
