Ultra-Processed Food and Frailty: Evidence from a Prospective Cohort Study and Implications for Future Research

Go to source). A new study published in Nutrients suggests that diets high in ultra-processed foods (UPFs) may contribute to small but measurable declines in physical function among older adults, even in the absence of frailty.

Researchers from Hebrew SeniorLife’s Hinda and Arthur Marcus Institute for Aging Research and Tufts University analyzed long-term data from the Framingham Heart Study to explore how UPFs influence mobility and strength — two key pillars of healthy aging.

How Processed Foods Weaken You

The study examined 2,547 adults from the Framingham Offspring Cohort, with an average follow-up of 10.8 years. Participants’ diets were assessed for ultra-processed food intake — items such as packaged snacks, frozen entrees, and sugary beverages that are typically high in salt, sugar, and additives but low in nutrients.

Over the decade-long study, 9.2% (233 individuals) developed frailty. While higher UPF intake was not associated with the onset of frailty, each additional daily serving was linked to a small but significant decline in gait speed (–0.001 meters/second per year). Among men, it also predicted a yearly reduction in grip strength (–0.02 kg per year).

“These findings suggest that while ultra-processed food consumption may not directly raise frailty risk, it could still contribute to subtle declines in mobility and strength over time,” said Dr. Shivani Sahni, Director of the Nutrition Program at the Marcus Institute and Associate Professor at Harvard Medical School.

Why Small Declines Matter

Physical function, including gait speed and grip strength, is a strong predictor of overall health, independence, and survival in older adults. Even slight declines can increase the risk of falls, disability, and loss of autonomy.

Ultra-processed foods are typically low in essential nutrients, fiber, and antioxidants, and high in sodium, refined carbohydrates, and artificial ingredients that promote inflammation and oxidative stress — biological processes that may impair muscle and nerve function.

Lead author Elsa M. Konieczynski, MS, from Tufts University, emphasized: “Limiting ultra-processed food intake and emphasizing whole, nutrient-dense foods may be a crucial step in preserving physical function and supporting healthy aging.”

Global Perspective: Aging and Diet Connection

As global populations age, maintaining mobility and independence has become a cornerstone of public health. Diet, often an overlooked factor in late-life function, may play a pivotal role. The findings add to growing global evidence that diets rich in whole grains, fruits, vegetables, and lean proteins, and lower in ultra-processed foods, may delay or prevent physical decline.

Experts say that even small dietary shifts can make a difference. Substituting packaged snacks with fresh fruits, or processed meats with legumes or fish, may support stronger muscles and healthier aging trajectories.

Stronger Aging Starts with Food

The message from the Framingham Heart Study is clear: ultra-processed foods might not make you frail — but they could make you slower and weaker over time.

Researchers call for further studies to explore the biological pathways linking UPFs to muscle health. However, for now, one step is certain: choosing whole, minimally processed foods may help keep you walking faster and gripping stronger for longer.
