The Claim
Higher intake of beans four times per week is associated with a 37% lower risk of heart disease mortality in 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.
Adults in rural China who eat beans four times a week have a 37% lower rate of death from heart disease compared to those who eat less, based on a 26-year study of 2,445 people.
See the scientific wording
Higher intake of beans four times per week is associated with a 37% lower risk of heart disease mortality in rural Chinese adults aged 40–69, based on 26 years of follow-up in a cohort of 2,445 individuals, suggesting legumes may be a protective dietary component in populations with low meat consumption.
Eating beans four times a week lowers the risk of dying from heart disease because the fiber in beans binds to bile acids in the gut, forcing the liver to use more cholesterol to make new bile acids, which lowers blood cholesterol. At the same time, antioxidants in beans neutralize harmful molecules in the blood that damage blood vessels, preventing plaque buildup and keeping arteries flexible.
