Does vitamin D really help reduce the risk of cancer death? According to the report of Pittsburgh School of Medicine in the United States and West China Hospital in China, vitamins can reduce the risk of cancer death by 16%, but vitamin D3 is more effective than D2.
Everyone believes that vitamin D can improve human immunity, but since last year, many studies have found that vitamin D is not effective in preventing diseases,British Medical JournalThe latest research in , covering more than 75,000 people, subjects including Europe, the United States and Asia, integrated 52 trials of systematic literature review analysis showed that no matter supplemented with vitamin D2 or D3, low dose or higher than 2000IU High dose, calcium supplementation alone or together, supplementation frequency, etc., were not significantly associated with overall mortality.
But only in cancer patients, vitamin D3 supplementation can significantly reduce the risk of death by 16%, which is the same as published last year in《new england journal》In the Brigham and Women’s Hospital report of Harvard Medical School, high-dose vitamin D supplementation was not associated with cardiovascular disease mortality, but reduced cancer mortality by 25%.
Expert Opinion
Huang Shuhui, a nutritionist at Postal Hospital, said that over the years, many studies in the medical field have found that vitamin D is of great help to immunity, mainly because active D3 will be released in macrophages or dendritic cells, T cells, and B cells. Lysosomal antimicrobial peptide (CAMP) in multinucleated leukocytes such as cells, this antimicrobial peptide is very related to the innate immunity to invasive bacterial infection in mammals, and it is present in various cells of the human body, if supplemented with activity Enough D3 can activate the antibacterial genes in the human body, regulate the immune function in macrophages and multinucleated white cells, and prevent diseases including cancer.
However, excessive supplementation of vitamin D3 is ineffective. Huang Shuhui said that some experts also recommend oral administration of high doses such as 800, 1200, and 2000 IU per day, but the most effective way to supplement active D3 is to bask in the sun and from foods containing D3; It is only helpful to the human body if it is taken from dried shiitake mushrooms, salmon and other foods.
