WCRF/AICR Third Expert Report — Diet, Nutrition, Physical Activity and Cancer

In plain English

A continuously updated meta-review covering 51 million people across thousands of studies, run by independent expert panels. The synthesis is unambiguous: fibre, whole grains, vegetables and fruit are consistently protective against multiple cancers; alcohol is consistently harmful, with no safe level for breast and several other cancers.

Why it matters

Fibre, whole grains, fruit/veg consistently protective; alcohol consistently harmful.

Caveats

Recommendations are population-level, not personalised. Evidence strength varies sharply by cancer site — strongest for colorectal, weaker for less-studied cancers.
