- Aflatoxin contamination in the developing world is associated with a very high rate of hepatocellular carcinoma.
- High intake of vegetables and fruit shows a consistent, inverse relationship with many cancers, including those of larynx, lung, and GI tract.
- High levels of vegetable consumption are associated with a reduced risk of colon cancer; alternatively, high levels of meat consumption appear to increase the risk.
- Obesity in adult life increases the risk of endometrial cancer as well as postmenopausal breast cancer and cancer of the kidney.
- Although difficult to prove, appropriate dietary modifications may significantly influence the incidence of certain cancers.
- The incidence of nasopharyngeal cancer in developing countries could be reduced by as much as 33%–50% by reducing intake of salt fish.
- Halving the median daily intake of aflatoxins produced by Aspergillus species may reduce the incidence of hepatocellular carcinoma in Africa and Asia by up to 40%.
