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

In older Chinese adults, each standard deviation increase in the protein-enriched dietary diversity index (PEDDI) is associated with a 26% higher hazard of achieving longevity, indicating a statistically significant link between protein-rich dietary variety and longer survival.
What the research says
1 studyThe 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.
