Beta carotene is an antioxidant, a pro-vitamin that the body converts into vitamin A
, and are mostly found in vegetables, yellow, red and dark green. Beta carotene is now available in supplement form and often in high doses. Because the antioxidant properties, previously believed that high doses of beta carotene supplements 
may help reduce the risk of cancer.
Various studies to date have been carried out to assess the benefits of beta carotene supplementation on the incidence of cancer. The expectation is the provision of beta carotene can help reduce the risk of cancer. But whether this is true? A meta-analysis studies (studies that examine the various studies) recently published in International Journal of Cancer earlier this year revealed a new fact. The study assesses nine previous studies and then summed to obtain a conclusion.
The result, overall beta-carotene supplements was not beneficial in reducing the risk of cancers, including pancreatic cancer, colon / colorectal, prostate, breast, skin (melanoma and non-melanoma). However, beta carotene supelementasi of 20-30 mg / day increased the risk of lung cancer by 16% and 34% of gastric cancer. For more realistic impact on the population of smokers and asbestos workers.
Finally, the study concluded that beta carotene supplements did not provide benefit in reducing the risk of cancer and even increase your risk of lung and stomach cancer. Therefore, I do not recommend taking supplements of beta-carotene for cancer prevention purposes.
