The Claim

Among older women in the top tertile of AHEI-2010 diet quality, higher consumption of ultraprocessed foods is associated with a 40% increased risk of frailty compared to lower consumption of ultraprocessed foods.

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

In plain English

Older women who eat the most ultraprocessed foods have a 40% higher risk of frailty than those who eat the least, even if their overall diet is otherwise high quality.

See the scientific wording

Even among older women with the highest diet quality (top tertile of AHEI-2010), those consuming the most ultraprocessed foods still have a 40% higher risk of frailty compared to those with the lowest UPF intake, indicating UPFs harm health independently of traditional nutritional indicators.

Why this might work

Eating lots of ultra-processed foods damages the gut lining, letting harmful bacterial toxins enter 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 leads to muscle loss and weakness, making the body more vulnerable to frailty.

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

    Even if older women eat lots of healthy foods like veggies and nuts, eating too many packaged snacks and sugary drinks still makes them more likely to become frail. The study proves UPFs are harmful on their own, even when the rest of the diet is good.
