Cancer does not appear to be directly caused by eating a certain food product, but some foods when consumed frequently and in large amounts may increase your risk of certain types of cancer.
Studies suggest many other factors influence your risk of cancer:

  • Beverages: pop, coffee, and alcohol may affect your risk of cancer
  • Life stage, genes, and other diseases appear to influence your risk of cancer
  • Body weight may have a significant impact on your cancer risk
  • Physical activity appears to promote decreased cancer risk
  • Tobacco smoking increases your risk for certain cancers

Current research

Food and cancer
Several foods have been identified as having potential cancer promoting and/or cancer inhibiting effects with respect to various cancers. Studies suggest that it may be the amount of a particular food and/or how often you consume that food that may contribute to the potential risk.
The following foods may be associated with an increased or decreased risk of cancer.

Vitamins, minerals, supplements and cancer

There is little conclusive evidence to support taking vitamin or mineral supplements to prevent cancer. In some instances certain vitamins and minerals when taken as a supplement may increase your risk of cancer.
Supplementation with the following nutrients may increase or decrease your risk of cancer.

Body weight and risk of cancer

Get moving

Being overweight or obese is highly correlated with increased risk of many cancers:
Cervical, colon, gall bladder, kidney, liver, ovarian and uterine cancers, and leukemia. Heavier post menopausal women have a higher risk of breast cancer.

  • Overweight is identified by a body mass index (BMI) greater than 25, and obese by a BMI of more than 30
  • Being underweight may also increase your risk of several cancers.

Life stage/genes/environment

There are many factors which influence your risk of cancer. For more information about these factors link to the information sites:
Cancer, breast cancer, colon cancer, pancreatic cancer, prostate cancer, uterine cancer, ovarian cancer, lung cancer, liver cancer, bladder cancer, testicular cancer, and kidney cancer
Physical activity

  • 150 minutes per week of moderate (walking) or vigorous (jogging/running) is associated with a reduced risk of several cancers.
  • As little as 75 minutes per week may reduce your risk of some cancers.
