The Claim

Higher adherence to healthful plant-based diets, as measured by a 10-unit increase in the healthful plant-based diet index (hPDI), is associated with a 6% lower risk of breast cancer.

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

People who eat more whole grains, fruits, vegetables, legumes, and nuts have a 6% lower risk of breast cancer for every 10-point increase in a diet quality score based on these foods.

See the scientific wording

Higher adherence to healthful plant-based diets, characterized by increased intake of whole grains, fruits, vegetables, legumes, and nuts, is associated with a 6% lower risk of breast cancer per 10-unit increase in the healthful plant-based diet index (hPDI), suggesting that dietary quality within plant-based patterns significantly influences cancer risk.

Why this might work

Eating more whole grains, fruits, vegetables, legumes, and nuts lowers the amount of active estrogen in the body and reduces long-term inflammation, which together slow the growth of breast cells that can turn into cancer.

  1. Study: Healthful and unhealthful plant-based diets and site-specific cancer risk: a systematic review and meta-analysis of observational studies

    People who eat more healthy plant foods like vegetables, fruits, whole grains, nuts, and legumes have a slightly lower chance of getting breast cancer, according to this big study of many people. Eating more unhealthy plant foods like sugary snacks didn’t help, but healthy ones did.
