The Claim

In older Chinese adults, each one standard deviation increase in the protein-enriched dietary diversity index (PEDDI) is associated with a 26% higher hazard ratio for achieving longevity, indicating a statistically significant positive association between protein-rich dietary variety and increased survival over time.

What the research says

Supports is higher

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

Challenges

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Older adults in China who eat a more varied diet with plenty of different protein-rich foods tend to live longer — each step up in dietary variety is linked to a better chance of living longer.

What the research says

1 study
  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 varied diet with more protein affects aging in older Chinese adults, and found that more variety in protein-rich foods was linked to living longer, just like the claim says.
