The Claim

An increase of one daily serving of vegetables is associated with an 11% lower risk of heart disease mortality among rural Chinese adults aged 40–69, with stronger associations observed for yellow/orange and other vegetables, based on 26 years of follow-up in a cohort of 2,445 individuals.

In plain English

Adults in rural China aged 40–69 who eat one additional serving of vegetables per day have a lower rate of death from heart disease over 26 years, with the strongest link seen for yellow and orange vegetables.

See the scientific wording

Increasing daily vegetable intake by one serving is associated with a 11% lower risk of heart disease mortality in rural Chinese adults aged 40–69, with stronger effects seen for yellow/orange and other vegetables, based on 26 years of follow-up in a cohort of 2,445 individuals.

Why this might work

Eating more vegetables, especially yellow and orange ones, delivers antioxidants that clean up harmful molecules in the blood, which protects the lining of blood vessels. This keeps blood vessels flexible and prevents plaque buildup, reducing the chance of heart attacks and strokes.

    In a long-term study of rural Chinese adults, people who ate one more serving of vegetables each day were less likely to die from heart disease — by about 11% to 23%. This matches the claim that eating more veggies lowers heart disease death risk.
