Dietary antioxidant capacity is associated with improved serum antioxidant status and decreased serum C-reactive protein and plasma homocysteine concentrations

Purpose To investigate the associations of dietary TAC from diet and supplements with serum antioxidant concentrations and serum C-reactive protein (CRP) and plasma total homocysteine ( t Hcy) in US adults. Methods This was a cross-sectional study. Food consumption data, serum antioxidant levels, an...

Description
Summary:Purpose To investigate the associations of dietary TAC from diet and supplements with serum antioxidant concentrations and serum C-reactive protein (CRP) and plasma total homocysteine ( t Hcy) in US adults. Methods This was a cross-sectional study. Food consumption data, serum antioxidant levels, and serum CRP and Plasma t Hcy concentrations of 4,391 US adults aged ≥19 years in the National Health and Nutrition Examination Survey 2001–2002 were analyzed. The USDA flavonoid and proanthocyanidin databases and dietary supplement data as well as antioxidant capacities of 43 antioxidants were also utilized. Result Serum CRP and plasma t Hcy concentrations were higher in older adults, smokers, and those with lower non-leisure time physical activity levels ( P
