Should we be taking high-dose nutrient supplements to protect us against some forms of cancer?
Research shows that certain high-dose nutrient supplements can be protective against some forms of cancer in high-risk groups of people. For example, there is considerable evidence that consumption of calcium supplements can decrease risk for colorectal cancer. However, use of some high-dose dietary supplements might cause cancer. Studies show that smokers who take supplements of ?-carotene have increased risk for lung cancer. Thus, the expert group concluded that consumption of nutrients through usual diet—as compared to supplements—is preferred. As such, dietary supplements are not recommended for cancer prevention.
