Raw potato juice does not fight cancer. Raw potato juice is usually made from potatoes and water and contains starch, protein, dietary fiber and other nutrients. Each 100 grams of potato contains 76 calories, of which 17.2 grams of carbohydrates, 0.7 grams of dietary fiber, 2 grams of protein, 0.2 grams of fat, 8 milligrams of calcium and 0.8 milligrams of iron. Boiled potato juice can be consumed as a supplementary source of starch, but it should not be eaten in excess, as it can easily cause gastrointestinal discomfort. Raw potato juice has no medicinal properties or effects, and therefore no anti-cancer properties. Cancer is usually associated with abnormal cell differentiation in the body and requires medication, surgery, radiotherapy and chemotherapy. Food cannot be used to treat the disease, so if you suffer from cancer, it is recommended to actively cooperate with the doctor’s treatment. Cancer can be prevented through a good daily routine, healthy diet, proper exercise and an optimistic mindset.
