The Claim

Higher consumption of ultraprocessed foods is associated with a 31% increased risk of frailty in older U.S. women over a 26-year follow-up period, independent of diet quality as measured by the Alternate Healthy Eating Index.

Source: Ultra-processed foods, unprocessed/minimally processed foods and risk of frailty in a cohort of U.S. females.

In plain English

Older U.S. women who eat more ultraprocessed foods have a 31% higher risk of developing frailty over 26 years, even when their overall diet quality is accounted for.

See the scientific wording

Higher consumption of ultraprocessed foods is associated with a 31% increased risk of frailty in older U.S. women over 26 years of follow-up, independent of diet quality as measured by the Alternate Healthy Eating Index, suggesting that food processing level itself may contribute to frailty risk beyond nutritional content.

Why this might work

Eating a lot of highly processed foods damages the gut lining, letting harmful bacterial substances leak into the bloodstream. This triggers constant low-level inflammation throughout the body, which breaks down muscle tissue and stops new muscle from forming. Over time, this weakens muscles and makes the body more vulnerable to frailty.

What the research says

1 study
  1. Study: Ultra-processed foods, unprocessed/minimally processed foods and risk of frailty in a cohort of U.S. females.

    Even when older women ate other healthy foods, those who ate more packaged snacks, sugary drinks, and ready-made meals still became weaker and more frail over time. This suggests the processing itself, not just bad nutrition, might be the problem.
