During human growth and development, vitamin is an indispensable substance to maintain human life activities and enhance disease resistance. It can make human body function normally. If a certain vitamin is lacking, the whole body will fall into a dangerous state.
Today, let's take a look at common vitamins A, B, C, D and E to see if they have anti-cancer functions?
1. Vitamin A
Vitamin A is of great significance in preventing lipid peroxidation, cardiovascular diseases and tumors. It has antioxidant effect and is an effective antioxidant for the body to capture active oxygen.
It plays a certain role in preventing breast cancer, gastrointestinal cancer, skin cancer, prostate cancer and other cancers. Through research, it has been found that if a person suffers from cancer, the insulin growth factor (TGF) in the body will increase, and vitamin A can inhibit the production of TGF, thus having a certain anti-cancer effect.
2. Vitamin B
Vitamin B, also known as vitamin B, is the general name of B vitamins and an essential part of metabolism in the body. Each vitamin B participates in key metabolic reactions.
These include vitamin B1, vitamin B2, vitamin PP, vitamin B6, pantothenic acid, biotin, folic acid, and vitamin B12. Different types of vitamin B deficiency can lead to different diseases.
Vitamin B1 deficiency can be manifested as beriberi, Wernicke Korsakoff syndrome, etc. Moderate vitamin B1 deficiency can be manifested as restlessness, weight loss, neurasthenia, irritability, etc.
The lack of vitamin B2 is closely related to the occurrence of esophageal squamous cell carcinoma and gastric adenocarcinoma. Vitamin B2 supplementation can reduce the occurrence of esophageal squamous cell carcinoma and gastric adenocarcinoma.
Although vitamin B is an indispensable vitamin for human body, the mechanism of vitamin B's anti-tumor effect is still unclear, and which tumor genes are affected by vitamin B need to be further studied.
Vitamin C, also known as ascorbic acid, is a good antioxidant, which can eliminate free radicals in the body, improve the immune capacity of the body, and fight against a variety of carcinogens. Vitamin C has detoxification effect, can activate the activity of oxidase, and help the human body detoxify in the process of food digestion and absorption.
It is widely found in fresh fruits and vegetables. Tomatoes, cauliflower, persimmon pepper, dark leafy vegetables, balsam pear, oranges, grapefruit, apples, grapes, kiwi fruits, fresh dates, etc. are all rich in vitamin C.
Studies have shown that vitamin C can block the synthesis of nitrosamines, a cancer inducing substance, and promote the formation of human lymphocytes.
Large doses of vitamin C can enhance the immune function of the body. Vitamin C can also increase the production of collagen and enhance the resistance to cancer cells. In addition, vitamin C can accelerate the excretion of carcinogenic compounds in the body and counteract the toxins of dead cancer cells. Vitamin C can also fight against cancer cells and cancer viruses by promoting the synthesis of interfering elements.
4. Vitamin D
Vitamin D is a fat soluble vitamin closely related to human health. Its main physiological functions are to maintain the balance of calcium and phosphorus, regulate bone metabolism, and regulate cell growth and differentiation and immune function.
Among natural foods, foods rich in vitamin D mainly include seafood, animal liver, animal skin, etc., such as cod liver oil, sardine, oysters, caviar, beef liver, lamb liver, chicken skin, etc.
Studies have shown that vitamin D can induce tumor cell apoptosis and inhibit tumor cell proliferation. For example, after the fresh cells of bone marrow cell leukemia patients are treated with 1,25-dihydroxyvitamin D3, the proliferation of white blood cells is inhibited and induced to differentiate. Not only bone marrow cell leukemia, 1,25-dihydroxyvitamin D3 also has obvious anti proliferation and induced differentiation effects on other tumor cells.
In addition, 1,25-dihydroxyvitamin D3 can also accelerate the release of tumor necrosis factor from macrophages, which has a wide range of anti-tumor effects. At the same time, vitamin D has immunomodulatory effect and is a good selective immunomodulator to improve immunity and resist the invasion of tumor cells.
5. Vitamin E
Vitamin E is one of fat soluble vitamins and also an important antioxidant nutrient in human body. It can delay aging, treat anemia, prevent and treat cardiovascular diseases, and is also related to reproductive function, so it is also called tocopherol.
In the anti-tumor effect of vitamin E, α- The activity of tocopherol succinate is the strongest, so there are more studies on the relationship between vitamin E succinate and tumor. Some studies have shown that vitamin E can also reduce the side effects of anti-cancer drugs and increase the efficacy of anti-cancer drugs, mainly from vegetable oils, such as soybean oil, corn oil, cotton seed oil and dried fruits.
