What are the benefits of selenium for cancer?
Selenium supplements for cancer can offer some protection for people who lack a sufficient level of minerals in their bodies. Studies on people show that people with low selenium levels face a higher risk of developing cancer, but once selenium reaches normal levels, the use of other selenium doses for cancer is probably not good. Animal studies show a significant benefit to selenium to prevent cancer, but there is no evidence that shows similar benefits in humans. In fact, too much selenium can pose health risks.
since the 1970s. Two -thirds of these research projects have shown that selenium could slow down or inhibit tumor growth by 15 to 35 percent. Animals giving more than 30 times the recommended daily amount of minerals for humans showed significant cancer protection. Only one of the experiments found no correlation.
Eight enzymes in the human body requestSelenium for antioxidant functions. Scientists believe that selenium levels can be changed by elevated levels of vitamin E and vitamin C. The selenium naturally occurs in rocks and soil, allowing mineral absorption to be absorbed. The recommended daily amount necessary for good health varies between medical organizations, but 30 to 50 micrograms per day is considered sufficient.
Most selenium research for cancer consists of observational studies. Scientists analyzed the diet of the participants of the studies and the level of selenium in the blood and noted which participants developed cancer later. Only a handful of these experiments included random scientific studies using the placebos control groups. Random studies have not shown any correlation between minerals and cancer prevention, namely skin and prostate cancer. Scientists who examined numerous previous studies in 2011 have said that too much selenuium can increase RIGIko diabetes.
One study added selenium to salt fed Chinese men who live in areas where selenium is rare in the soil. They also received high doses of carotene and vitamin E results. They showed fewer cases of esophageal and stomach cancer. Scientists could not determine whether selenium supplements corrected a shortage or what role the vitamins played in findings.
Scientists concluded that too small selenium or too many minerals could pose health risks. The toxic effects of excessive selenium include a disturbed immune system, fatigue, hair loss and thin nails. Some scientists recommend accepting more than 200 selenium micrograms a day to avoid side effects.
