Diet, Nutrients, Vitamins & Cancer

Many foods, especially fruits and vegetables, contain substances that help to prevent the formation of cancers or actively attack existing cancers. This seems to be one of the purposes of food and is a part of the economy of nature. For cancer prevention, a diet containing high-quality fruits and vegetables is essential. Ideally, fruit and vegetables should not only be free of herbicides, fungicides, pesticides, etc. but should also be grown on soil that has not been depleted of natural minerals and nutrients. A number of experts have pointed out that for cancer treatment rather than prevention, it may be too late for a dietary regime alone to result in a cure. Concentrated extracts should also be considered. However, to maintain or regain health, the importance of a whole food diet cannot be over-emphasized.

Many well-known vitamins and other antioxidants have been shown to help lessen the side effects of chemotherapy and radiotherapy. Some also possess anti-cancer properties. However, some antioxidants can inhibit the cytotoxic effect (and hence their ability to kill cancer cells) of chemotherapy drugs, while others can enhance their cytotoxic effect (such as vitamin E and 5FU). The subject is complex because there are so many antioxidants and so many chemotherapy drugs, and the full nature of all the interactions is unknown. So if you are intending to take vitamins and antioxidants along with chemotherapy, it is best to do further research and/or ask a medical professional who knows about these things.

Dietary supplements are a huge industry, and quality varies considerably, so it is important to get high-quality vitamins and antioxidants. Vitamins etc. that have been extracted or prepared in such a way as to maximize their bioavailability are preferable because the body is able to absorb greater quantities. There is little point in taking large doses of vitamins if most of them are never absorbed into the body or if they are simply excreted in your urine.

Vitamin C High Intravenous Dose

Vitamin C, also known as ascorbic acid, was first suggested as a cancer treatment in 1976, by Linus Pauling, winner of the Nobel prize for chemistry in 1954 and the Nobel peace prize in 1964. His research showed that life expectancy in terminally ill cancer patients who were given 10gms of vitamin C per day was significantly increased, compared to those who were not. Various studies since then have produced similar results, with survival times being generally doubled. Other studies, however, have found no benefits, and have concluded that any positive benefits are those of a placebo. In practice, doctors who have used the method have found that it works with some patients and not with others. Why this should be so is presently unknown.
