Superfood is a marketing term for food claimed to confer health benefits resulting from an exceptional nutrient density.[1][2] The term is not commonly used by experts, dietitians and nutrition scientists, most of whom dispute that particular foods have the health benefits claimed by their advocates. Even without scientific evidence of exceptional nutrient content, many new, exotic, and foreign fruits or ancient grains are marketed under the term – or superfruit or supergrain respectively – after being introduced or re-introduced to Western markets.

In 2007, the marketing of products as "superfoods" was prohibited in the European Union unless accompanied by a specific authorized health claim supported by credible scientific research.[3]
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.[2][7] These contrast with benign tumors, which do not spread.[7] Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements.[1] While these symptoms may indicate cancer, they can also have other causes.[1] Over 100 types of cancers affect humans.[7]

Tobacco use is the cause of about 22% of cancer deaths.[2] Another 10% are due to obesity, poor diet, lack of physical activity or excessive drinking of alcohol.[2][8][9] Other factors include certain infections, exposure to ionizing radiation, and environmental pollutants.[3] In the developing world, 15% of cancers are due to infections such as Helicobacter pylori, hepatitis B, hepatitis C, human papillomavirus infection, Epstein–Barr virus and human immunodeficiency virus (HIV).[2] These factors act, at least partly, by changing the genes of a cell.[10] Typically, many genetic changes are required before cancer develops.[10] Approximately 5–10% of cancers are due to inherited genetic defects.[11] Cancer can be detected by certain signs and symptoms or screening tests.[2] It is then typically further investigated by medical imaging and confirmed by biopsy.[12]
