Calcium is the main component of bones and teeth. In addition, calcium plays an important role in human physiological functions, including the coagulation process of calcium ions, nerve, muscle and heart functions. If calcium deficiency is severe, not only for children's development, but also for adults, the bone risk is reduced, and osteoporosis and fractures are increased. Severe calcium deficiency includes numbness, tingling, spasm and arrhythmia, which may lead to death if not corrected. Of course, there is no other disease, and it is usually impossible to have a serious shortage.

The relationship between calcium and cancer mainly focuses on the following cancers: colorectal cancer, breast cancer and prostate cancer.

Compared with the people with the lowest calcium intake, the people with the highest dietary and calcium intake have a slightly lower risk of colorectal cancer. However, if you take about 1200 mg daily, the risk of colorectal cancer in men who benefit from calcium will be reduced by 20%, and the risk of colorectal cancer in patients will be reduced by about 30%.

However, even after some studies, it is concluded that calcium cannot reduce the risk of colorectal cancer. Therefore, although there is a lot of evidence that calcium may have a certain protective effect on colorectal cancer, the evidence of potential benefits of calcium supplements is limited and inconsistent. Therefore, the National Cancer Institute does not recommend the use of calcium supplements to reduce colorectal cancer or any other type of cancer.

So there is too much calcium. What does it have to do with cancer? The focus of this study is prostate cancer. For example, a prospective survey on cancer and nutrition in Europe analyzed more than 65,438+042,000 male foods (meat, poultry, fish, dairy products, etc.) related to the risk of prostate cancer. ), protein and calcium intake, it is found that a large amount of protein or calcium is ingested in dairy products, which is related to the increased risk of prostate cancer. However, calcium from non-dairy sources has nothing to do with risk. In other words, the risk of prostate cancer increases, and calcium in dairy products may be related, but calcium supplementation seems to be a lot.

In addition, the relationship between calcium supplementation and breast cancer is also inconsistent. Some studies believe that calcium can reduce breast cancer, but others believe that calcium supplementation will increase the risk of breast cancer.
