Increasing the amount of antioxidants in your diet is thought to be one way to improve your health. If antioxidants do have a beneficial effect, one way to measure that is to examine possible changes in the levels of inflammatory markers in your blood.
Participants were asked to consume an antioxidant supplement including carotenoids, mixed tocopherols, vitamin C and selenium, or a placebo for 8 weeks. The doses of antioxidants will be similar to the amounts suggested by the United States Department of Agriculture (USDA) recommended daily allowances (RDA). In addition, a group of participants will be asked to change their usual eating habits and consume more of certain foods that are naturally good sources of the four antioxidants contained in the pills.
Eligible participants were asked to come to the Stanford Campus for 3 fasting blood draws over the period of 8 weeks and to complete diet and physical activity questionnaires at the beginning, middle, and end of the study period.
