The Claim

In older Chinese adults aged 65 years or older, a higher score on the protein-enriched dietary diversity index (PEDDI) is associated with a 20% increase in the odds of successful aging per standard deviation increase in PEDDI score, indicating that greater dietary variety with emphasis on protein intake may support healthier aging outcomes.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Eating a more varied diet with plenty of protein might help older Chinese adults age more healthily — for every step up in diet quality, the odds of aging well go up by 20%.

See the scientific wording

Among older Chinese adults aged 65 years or older, a dietary pattern rich in protein and diverse food sources, as measured by the protein-enriched dietary diversity index (PEDDI), is associated with a 20% higher odds of successful aging per standard deviation increase in PEDDI score, suggesting that greater dietary variety with emphasis on protein may support healthier aging outcomes.

  1. Study: Associations of diet patterns with successful aging, longevity, and extreme longevity: a prospective cohort study among Chinese adults 65 years or older

    The study looked at how eating a variety of foods with more protein affects healthy aging in older Chinese adults, and found that people with higher scores on this diet measure were more likely to age successfully, just like the claim says.
