As part of Sun Acupuncture’s series on cancer, today we delve into foods, supplements and how we nourish ourselves. Because there is a lot of information out there and new supplement claims can be made by just about anyone with a computer, we are going to focus on the recommendations of an expert panel whose job it is to analyze data for this very reason. The 8 recommendations of the World Cancer Research Fund and the American Institute for Cancer Research on nutrition for the prevention of cancer are outlined below. According to the panel, cancer survivors should follow the same recommendations to prevent recurrence. Active cancer patients, on the other hand, should not seek any food-based cure for cancer as the evidence does not support it.
A personal note before these are laid out: The spirit with which we go about our business is just as important as the business being done. In other words, militant, joyless adherence to these guidelines rooted in fear will create a negative atmosphere in the body that can lend itself to dis-ease and injury. It is of paramount importance that we enjoy our meals, share them with loved ones, and nourish our spirit as well as our body as a result. Meal time should have a ceremony attached to it that prepares the body for digestion. Cooking serves; having a special place to eat that is away from the TV serves; a prayer or quietness before the meal serves; and a certain gentle rhythm to the meal where food and drink are tasted and assimilated with conscious presence helps us gain the benefits of nutrition without knotting up our belly. If you notice discomfort after a meal, consider not only the food that was eaten, but also the atmosphere in which it was eaten and this principle will come alive to you. This is the Tao of eating!

A couple things jump out here. For diet, adhering as closely as possible to a “mediterranean diet” has the most research behind it for the prevention of cancer. See Sofi F, et al. Adherence to Mediterranean diet and health status: meta-analysis. BMJ 2008;337:a1344 for more information.
For supplements, there is not enough evidence to back up the claim that any supplement can prevent cancer. That includes Wheat grass, Gogi, Noni, AÇAI, Pomegranate, Mangostin, EGCG/green tea, resveratrol, Vitamin A, C and E, selenium. Research is still underway assessing the potential of Vitamin D in Cancer Prevention as well as overall health benefits. This is particularly important to us Minnesotans because we need sunlight to get it. Other than that, the 20+ billion dollar supplement industry should be off the radar when considering its evidence in cancer prevention. Spend your money on real, local, organic foods or evidenced cancer support modalities instead!
