Vitamin D is a “sharp weapon” for cancer prevention! Doctor’s roll call: people with these four characteristics should be filled as early as possible

Vitamin D supplements may help prevent potentially serious side effects of cancer immunotherapy, according to a new study published June 22 in the peer-reviewed journal of the American Cancer Society. < / P > < p > prevention of colorectal cancer. Epidemiological data show that the combined use of vitamin D and calcium can significantly reduce the incidence rate of colorectal cancer. The researchers followed 87998 women and 47344 men for 10 to 16 years. After that, 626 women and 399 men suffered from colorectal cancer. Their calcium intake was analyzed. People who ate more than 700 mg of calcium a day had a 42% lower risk of colorectal cancer than those with less than 500 mg of calcium per day. At the same time, calcium can effectively reduce the incidence of colorectal cancer only in patients with high serum 25-oh-d3 level, that is to say, they should be taken together with vitamin D. Both calcium and vitamin D can reduce the risk of colorectal cancer, but their mechanisms are different. The mechanism of action of calcium is that it can inhibit the proliferation of intestinal epithelial cells by binding with the secondary cholic acid and fatty acid in the intestine to achieve the purpose of prevention. Vitamin D, on the other hand, can induce E-cadherin, further inhibit b-catenin, and then produce anti cell proliferation effect, and finally prevent the occurrence of colorectal cancer. < / P > < p > to prevent the deterioration of low-grade prostate cancer. Dr. Bruce Hollis of South Carolina Medical University found in 2015 that vitamin D supplementation can slow or even reverse the invasion of prostate cancer. This is mainly aimed at low-grade prostate cancer. His study found that after one year of vitamin D supplementation, 55% of patients had remission, and some patients’ tumors even disappeared completely. The mechanism of action is that vitamin D can induce the production of a protein in the body. Growth differentiation factor 15 is a type of protein. Its production can reduce the inflammation of patients. However, many invasive prostate cancer patients do not have the protein quality of growth differentiation factor 15. Therefore, vitamin D supplementation can effectively reduce the inflammation of patients with low-grade prostate cancer, so as to further slow down the disease, control the disease does not develop, and even can not carry out surgery and radiotherapy. However, Dr. Hollis also said that whether vitamin D can prevent and treat prostate cancer is unknown, but it can prevent low-grade prostate cancer from deteriorating. < / P > < p > to prevent breast cancer. If vitamin D is effective in preventing breast cancer in 2017, it can reduce the incidence of breast cancer. < / P > < p > the researchers randomly divided 2300 postmenopausal women into two groups: one group took vitamin D and calcium daily, the other group took placebo, and the group taking vitamin D received three times the standard dose of 600iu, or 1800iu a day. After four years of continuous treatment, the incidence rate of breast cancer was 30% in women taking vitamin D and calcium. Dr. Joan Lappe, who led the study, said that healthy cells in the body need vitamin D to maintain the necessary operation. If vitamin D is deficient for a long time, the genes of healthy cells tend to change and mutate. Therefore, vitamin D supplementation can help prevent cancer. < / P > < p > unlike other members of the “big family” of vitamins, vitamin D is relatively low in food, and it is almost absent in vegetables and cereals. However, vitamin D is relatively abundant in fish, animal viscera, egg yolk and dairy products. < p > < p > generally speaking, the daily intake of vitamin D for adults should be maintained at 600 IU, that is, about 15 micrograms. Eat too much is not good, because vitamin D is fat soluble, too much easy to cause hypercalcemia, nausea, muscle weakness and vague consciousness and other symptoms. In addition to food, sun exposure is also the best way to supplement vitamin D. However, most people are worried about tanning. In fact, as long as it is not exposed to the sun for a long time, occasional exposure to the sun will not cause too much damage to the body and skin. < / P > < p > fatigue. Vitamin D can enhance people’s immunity. If the body is lack of vitamin D, the body will feel tired, especially when the sun is not enough, the synthesis of vitamin D is blocked, and the body may be tired and weak. In this case, it can be alleviated by dietary supplements or drugs. < / P > < p > depressed. Vitamin D improves cognitive ability and regulates serotonin. If you feel depressed for a period of time, it may be vitamin D deficiency. < / P > < p > osteoporosis. If children lack vitamin D, they will suffer from rickets, the elderly with the loss of calcium in the body, will be troubled by osteoporosis. Appear osteoporosis, can bask in the sun more, food can eat more eggs, dairy products and fish. < / P > < p > dry skin. If the body’s vitamin D deficiency, there will be dry skin. Especially in the northern region in winter, due to the weak sunlight, many people will have dry skin. In addition to dry air, this situation may also be vitamin D deficiency. If you blindly use moisturizer, do not find the real reason, may aggravate the lack. < p > < p > [1] World Chinese digest Journal 2005.10.15 < A= target=_ blank>Skip to content
