“…This study was an extension of our previously published results of interventional trials in which consumption of strawberries (500 g daily) increased fasting non-urate plasma DPPH radical scavenging activity (10,11) while had no effect on FRAP. (11) It was executed just after interim analysis of these variables, therefore, the same strawberry pulp was used for dietary intervention.…”

“…(1–3) This may include cardiovascular protection, e.g., reduction of atherosclerotic markers in subjects with metabolic syndrome or decrease in low-density lipoprotein peroxidative damage; (4–7) anti-inflammatory activity (attenuation of the postprandial inflammatory response); (6,8,9) attenuation of the risk of oxidative stress by augmentation of plasma antioxidant defense (7,10–13) and suppression of baseline formation of reactive oxygen species by blood phagocytes. (11) These plausibly pro-healthy effects of strawberries can be attributed to the presence of numerous polyphenols such as anthocyanins (e.g., pelargonidin, cyanidin), ellagic acid and ellagitanins, phenolic acids (chlorogenic acid, hydroxycinnamic acid), catechin, quercetin and vitamins (ascorbic acid, folates). (1–3) Apart from the direct antioxidant and anti-inflammatory properties polyphenols can modulate the expression of genes involved in cell metabolism and survival, enzymatic antioxidant defense and systems of DNA protection and repair.…”

Strawberries can augment plasma antioxidant activity, but this may be confounded by selection of methods, time of blood sampling and concomitant dietary restrictions. We examined the effect of strawberry consumption on ferric reducing ability (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity (DPPH-test) of native and non-urate plasma in healthy subjects on their usual diet. Eleven subjects consumed strawberries (500 g daily) for 9 days. Fasting and 3-h postprandial plasma and 24-h urine collection were obtained before, during and after strawberry course for FRAP, DPPH-test and polyphenols determination. Fifteen subjects served as a control in respect to plasma antioxidant activity changes and effect of 300 mg of oral ascorbate. First, 5th and 9th strawberry dose increased 3-h postprandial DPPH-test by 17.4, 17.6 and 12.6%, and FRAP by 15.5, 25.6 and 21.4% in comparison to fasting values in non-urate plasma (p<0.05). In native plasma only a trend was observed to higher postprandial values for both tests. Strawberries increased urinary urolithin A and 4-hydroxyhippuric acid whereas plasma polyphenols were stable. No changes of FRAP and DPPH-test were noted in controls and after ascorbate intake. Strawberries transiently increased non-urate plasma antioxidant activity but this cannot be attributed to direct antioxidant effect of polyphenols and ascorbate.

“…A decrease in resting luminol enhanced whole blood chemiluminescence was observed following regular strawberry consumption which may suppress baseline formation of oxidants by circulating phagocytes and decrease the risk of systemic imbalance between oxidants and anti-oxidants and be one of mechanisms of the health-promoting effects of strawberry consumption [35]. The major antioxidant protection in strawberries is from peroxyl, hydroxyl and superoxide-anion radicals (Table 1).…”

Abstract. BACKGROUND:Fruits and berries are known to contain relatively high amounts of antioxidant/bioactive compounds. Several methods have been used for measurement of antioxidant capacity (AC), but not all methods have direct relevance to in vivo antioxidant status. OBJECTIVE: Determine AC in berry/fruit samples, processed berry products, and purified compounds by utilizing 5 different biologically relevant free radical/oxidant sources. METHODS: Samples were assayed for AC capacity using 5 different free radical/oxidant sources: peroxyl radical (ORAC), hydroxyl radical (HORAC), peroxynitrite (NORAC), superoxide anion (SORAC) and singlet oxygen (SOAC)]. Total AC (sum of AC with 5 individual radicals) was expressed as Oxygen Radical Absorption Capacity using Multiple Radicals (ORAC MR5 ). RESULTS: SOAC contributed more than 60% of ORAC MR5 in blackberries, sweet and tart cherries; and no detectable levels of SOAC were found in strawberries, black currants and raspberries. Whole fruit purees of mango, wild blueberry and cherry contained 95, 85 and 67% respectively of total ORAC MR5 from SOAC. However, freeze dried wild blueberry powder from same production season had only 28% as SOAC and 42 and 22% as ORAC and HORAC. Blueberry/Pomegranate and Mango/Pineapple smoothies had 67% and 77% of ORAC MR5 as SOAC. CONCLUSIONS: The antioxidant quenching potential using 5 different radical/oxidant sources of different berries and fruits varied widely and understanding this variation may be helpful in understanding health benefits of different berries and foods.
