The Claim

From 1990 to 2021, age-standardized mortality rates (ASMR) and disability-adjusted life year rates (ASDR) for gastric cancer associated with high sodium intake decreased consistently in China, Japan, Republic of Korea, and Mongolia, with Republic of Korea exhibiting the largest reductions (AAPC -4.53 for ASMR and -5.04 for ASDR).

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.

In plain English

Fewer people in China, Japan, Korea, and Mongolia died or got sick from stomach cancer linked to eating too much salt between 1990 and 2021, with Korea seeing the biggest drop.

    The study looked at how high salt intake affects stomach cancer in four Asian countries and found that death and disability rates dropped over time, especially in South Korea, which matches exactly what the claim says.
