Diets built around vegetables, wholegrains, legumes, nuts, fish and olive oil, with little red or processed meat, are linked with lower cancer risk and better survival after diagnosis. The evidence is strong for the pattern, weak for any single food.
The World Cancer Research Fund Continuous Update Project and the American Cancer Society 2020 guideline converge on a dietary pattern rather than individual nutrients: high in wholegrains, vegetables, fruit and legumes; limited red meat, and processed meat, sugar-sweetened drinks and alcohol avoided. Prospective cohorts show 10-20% lower total cancer incidence and lower cancer mortality with high adherence to Mediterranean or healthy-plant-based indices; colorectal cancer has the most consistent association (fibre, wholegrains, dairy protective; red and processed meat harmful). Randomised evidence is thinner: PREDIMED (a cardiovascular trial) reported fewer breast cancers on Mediterranean diet with extra-virgin olive oil in a small secondary analysis; WHEL and WINS in breast cancer survivors showed that a low-fat or high-vegetable diet did not reduce recurrence on its own. Observational associations after diagnosis (CALGB 89803 in colon cancer: Western pattern associated with recurrence) are consistent but confounded by overall health behaviour.
High fibre feeds a diverse gut microbiome and short-chain fatty acid production; low glycaemic load and energy density reduce insulin and adiposity; polyphenols and unsaturated fats lower inflammation; displacement of processed meat lowers exposure to nitrosamines and haem iron.
