Strawberry consumption improves plasma antioxidant status and erythrocyte resistance to oxidative haemolysis in humans.

摘要: Significant increases in the plasma total antioxidant capacity (TAC) have already been reported after acute intake of strawberries. In addition, antihaemolitic effects strawberry extracts recently demonstrated vitro, revealing that part properties bioactive compounds could lie their localisation within cell membranes. However, there is a lack research evidence from vivo protracted consumption studies. We carried out 16-day pilot study where 12 healthy subjects ingested 500 g antioxidants-rich strawberries daily, and we evaluated potential fruit on biomarkers cellular status. A significant increase fasting TAC serum vitamin C concentrations were progressively observed during period supplementation. An enhanced resistance to haemolysis was also both AAPH-treated untreated erythrocytes, collected consumption. The results obtained this work suggest regular antioxidant-rich may exert an improvement status defenses human erythrocytes.
