What is the connection between beta carotene and cancer?

so far the only consistent evidence of the connection between beta carotene and cancer is negative. In fact, beta carotene supplements can increase the risk of certain types of cancer, especially lung cancer in smokers. Scientists still study the possibility that other carotenoids found naturally in fruits and vegetables can be more factor in reducing cancer risk than beta carotene. Overall, research suggests that vitamin A can be obtained by many health benefits whose beta carotene is a type of different foods. Vitamin A can be obtained by consuming the liver, egg yolks, diary products and fish oils. Beta Karotene is a vitamin A, which has been converted into a small intestine into retinol after food food such as squash, apricots and peaches or carrots, broccoli and spinach.

Vitamin A and beta carotene belongs that can protect cells from damage caused by "free radicals". Free radicals are molecules in the body responsible for cell damage that can lead to cancer. Many foods thatThey are orange, rich in beta carotene. These include pumpkins, mango and melon. Green vegetables such as spinach and kale also contain a large amount of beta carotene.

There was a significant amount of research concerning beta carotene and cancer. Some studies have combined food food, which are a good source of beta carotene or vitamin and with a lower risk of cancer. It is not definitely known whether the reduced risk was exclusively caused by added vitamin or caused by other substances in the food or generally healthy eating. Animal studies have shown that vitamin A and other retinoids that strengthen the immune system can reduce existing cancerous tumors or strengthen a certain Cancer treatment.

Clinical studies involving beta carotene and cancer have found that the risk of lung cancer is not reduced when using vitamin A.It can even increase the risk of lung cancer. The results of studies on the effect of vitamin and other forms of cancer were inconsistent and inconclusive.

Most of the information available about any connection between beta carotene and cancer suggests that beta carotene itself may not be an effective cancer prevention tool. Other carotenoids found in fruits and vegetables may be more important in protecting healthy body cells. It would seem that all different micronutrients found in a healthy diet of fruits, vegetables, grains and legumes collected in combination may be better defense against cancer than any individual vitamin supplements.
