Flavonoid-Rich Diets Linked to Lower Breast Cancer Risk and Improved Metabolic Health

A long‑term study of 93,271 women from the UK Biobank followed for nearly 12 years found that regular consumption of flavonoid‑rich foods—such as apples, citrus fruits, berries, grapes, peppers, onions, tea and dark chocolate—was associated with a reduced incidence of breast cancer, even among women with a high genetic predisposition.

Separate research on a “green Mediterranean” diet, a plant‑based, polyphenol‑rich variant of the traditional Mediterranean eating pattern, reported favorable effects on metabolic and cardiometabolic markers compared with the conventional Mediterranean diet. The green Mediterranean diet emphasizes vegetables, fruits, whole grains, legumes and plant proteins while markedly reducing meat and dairy intake, thereby increasing dietary polyphenol exposure.

Both studies suggest that diets high in natural polyphenols may help prevent serious diseases, including breast cancer and metabolic disorders.
