- “The importance of antioxidants in reducing risks of chronic diseases has been well established; however, antioxidant intakes by a free-living population have not yet been estimated adequately.”1
Researchers from Department of Nutritional Sciences, University of Connecticut, Storrs, Connecticut; Department Foods and Nutrition, Kookmin University, Seoul, Korea; Department of Food and Nutrition, Ansan College, Ansan, Korea; and Department of Food Science and Human Nutrition, Michigan State University, East Lansing, Michigan; have presented an article titled: “Estimation of Antioxidant Intakes from Diet and Supplements in U.S. Adults.”
The researchers from Storrs, Seoul, Ansan and East Lansing; have also noted:
- “In this study, we aimed to estimate total antioxidant intakes from diets and supplement sources in the U.S. population.”
- “The USDA Flavonoid Database, food consumption data, and dietary supplement use data of 8809 U.S. adults aged >/=19 y in NHANES 1999-2000 and 2001-2002 were used in this study.”
- “Daily total antioxidant intake was 208 mg vitamin C (46 and 54% from diets and supplements, respectively), 20 mg alpha-tocopherol (36 and 64), 223 mug retinol activity equivalents carotenes (86 and 14), 122 mug selenium (89 and 11), and 210 mg flavonoids (98 and 2).”
- “Antioxidant intakes differed among sociodemographic subgroups and lifestyle behaviors.”
- “Energy-adjusted dietary antioxidant intakes were higher in women, older adults, Caucasians, nonconsumers of alcohol (only for vitamin C and carotenes), nonsmokers (only for vitamin C, vitamin E, and carotenes), and in those with a higher income and exercise level (except for flavonoids) than in their counterparts (P < 0.05).”
- “Consumption of fruits, vegetables, and whole grains may be a good strategy to increase antioxidant intake.”
- “The possible association between antioxidant intake and the prevalence of chronic diseases should be investigated further.”
