Published in the American Journal of Epidemiology, a new 10-year analysis of more than 77,000 adults, men and women ages 50 to 76, revealed long term use of high-dose beta carotene supplements may heighten the risk of lung cancer, especially in smokers. Scientists used questionnaires to assess participants’ intake of dietary supplements and then tracked them for the next four years. These findings mirror a 2007 study showing vitamin C and E and folate supplements do not decrease the risk of lung cancer; ScienceDaily explains.
According to Dr. Fuhrman high-dose beta carotene supplements interfere with the absorption of antioxidants, like carotenoids and other antioxidants found in fruits and vegetables. This can increase cancer-risk. That’s why Dr. Fuhrman’s formulates his vitamins without beta carotene.
But getting beta carotene from veggies is just fine! Foods like carrots, mangos and oranges, as well as leafy greens like cabbage, Bok Choy and broccoli are loaded with beta carotene and other health-protecting antioxidants and phytochemicals.
