Scientists are confident that the consumption of vitamins has no effect in preventing death or illness in the general population, and recent studies have shown that excess intake of antioxidants increases the risk of cancer. In many cases, the consumption of large amounts of vitamins in the form of supplements (especially vitamins A, C, E and beta carotene) can be harmful, because it increases the risk of cancer and other diseases. In addition, some vitamins and supplements may do more harm than good, warns Dr. Mickey Barber and believes that five vitamins and supplements should be thoroughly checked, including calcium, calcium supplements, vitamin supplements, vitamins and minerals older than 50 years. Barber added that the food is the best way to get the body the vitamins and minerals for optimal function of cells, although all vitamins can be obtained at every meal. “So eat a variety of foods, organically grown without pesticides and hormones, cook meals yourself and don’t eat at restaurants, because otherwise you will need a multivitamin,” said Barber.
