The Claim
Higher daily intake of non-whole grains is associated with a 14% lower risk of gastric cancer mortality among rural Chinese adults aged 40–69 over a 26-year follow-up period.
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 rural Chinese adults aged 40–69, higher daily consumption of non-whole grains is linked to a 14% reduction in deaths from gastric cancer over 26 years.
See the scientific wording
Higher daily intake of non-whole grains is associated with a 14% lower risk of gastric cancer mortality in rural Chinese adults aged 40–69, based on 26 years of follow-up in a cohort of 2,445 individuals, suggesting that staple grain consumption may play a protective role in gastric cancer outcomes in populations with high baseline incidence.
Eating more refined grains like white rice and white flour increases the amount of fiber in the gut, which binds to bile acids released during digestion. This binding stops bacteria from turning those bile acids into harmful forms that damage stomach lining cells. With fewer of these harmful bile acids, stomach cells divide less and suffer less DNA damage, which lowers the chance of cancer developing and killing the person.
What the research says
1 studyIn a long-term study of rural Chinese adults, those who ate more white rice or refined flour (non-whole grains) were 14% less likely to die from stomach cancer than those who ate less — exactly what the claim says.
