Postprandial lipemia, glycemia and oxidative stress may affect the occurrence of cardiovascular disease. The purpose of the present intervention study was to investigate the effect of a spread cheese enriched with mountain tea (Sideritis sp.) and orange peel (Citrus sinensis) extract on postprandial metabolic biomarkers in healthy volunteers. In a cross-over design, 14 healthy subjects 20–30 years old were consumed either a meal rich in fat and carbohydrates (80 g white bread, 40 g butter and 30 g full fat spread cheese) or a meal with the spread cheese enriched with 6% mountain tea–orange peel extract. Differences in postprandial total plasma antioxidant capacity, resistance of plasma to oxidation, serum lipids, glucose and uric acid levels were evaluated at 0, 1.5 and 3 h after consumption. Plasma total antioxidant capacity was significantly increased 3 h after the consumption of the meal in the presence of the extract-enriched cheese, compared to the conventional cheese (p = 0.05). Plasma resistance to oxidation was increased at 30 min in the Functional meal compared with the Control meal. A tendency to decrease the postprandial rise in glucose and triglyceride levels, 1.5 h and 3 h, respectively, after the intake of the meal with the extract-enriched cheese was observed (p = 0.062). No significant changes in the concentrations of the remaining biomarkers studied were observed (p > 0.05). Further studies with a larger sample are needed in both healthy adults and patients with cardiovascular disease to draw safer conclusions about the postprandial effect of the extracts on metabolic biomarkers that predict cardiovascular risk.

Post-prandial lipemia, glycemia and oxidative stress may affect the outcome of cardiovascular disease. It has been investigated that the enhancement of spread cheese with mountain tea (Sideritis sp.) and orange peel extract, may reduce post-prandial metabolic biomarkers in healthy volunteers. The purpose of the present pilot study was to investigate the possible post-prandial bioactivity of such a spread cheese. In the framework of cross-over design, nine healthy volunteers 20–30 years old, consumed a meal, rich in fat and carbohydrates (80 g white bread, 40 g butter and 30 g full fat spread cheese). After a week washout period, the same volunteers consumed the same meal with the spread cheese, enhanced with 6% mountain tea–dried orange peel extract. Blood sampling took place before, 1.5, 3 and 5 h after meal consumption. Total plasma antioxidant capacity, serum lipids, glucose, uric acid and anticoagulant activity were measured at each time point. There was a statistically significant increase in the antioxidant capacity of plasma 3 h after the meal consumption in the presence of cheese enhanced with extract, compared to the consumption of conventional cheese (p < 0.05). The increase rate of glucose and triglycerides showed a decreasing tendency, 1.5 h after eating the meal with the extract. The remaining biomarkers did not show statistically significant differences (p > 0.05). More studies in a larger sample are needed to draw safer conclusions about the effect of extract on metabolic biomarkers, such as oxidative stress, lipemia and glycemia.

Berries have shown several cardiovascular health benefits and have been associated with antioxidant functions in experimental models. Clinical studies are limited. We examined the antioxidant effects of freeze-dried strawberries (FDS) in adults [n=60; age:49±10years; BMI:36±5 kg/m2(mean ± SD)] with abdominal adiposity and elevated serum lipids. Participants were randomized to one of the following arms: low dose strawberry (25 g/day FDS), low dose control beverage (LD-C), high dose strawberry (50 g/d FDS), and high dose control beverage (HD-C) for 12 weeks. Control beverages were matched for calories and total fiber. Plasma antioxidant capacity, trace elements (copper, iron, selenium, and zinc), whole blood glutathione (GSH), and enzyme activity (catalase, glutathione peroxidase, and glutathione reductase) were examined at screening (0 week) and after 12 weeks’ intervention. At 12 weeks, plasma antioxidant capacity and glutathione levels were higher in the strawberry versus control groups (low and high dose FDS: 45% and 42% for plasma antioxidant capacity and 28% and 36% for glutathione, resp.); glutathione was higher in the high versus low dose strawberry group (allp<0.05). Serum catalase activity was higher in the low dose strawberry (43%) versus control group (p<0.01). No differences were noted in plasma trace elements and glutathione enzyme activity. Dietary strawberries may selectively increase plasma antioxidant biomarkers in obese adults with elevated lipids.

Abstract The aim of the present study was to evaluate antioxidative activities of the encapsulated and unencapsulated bitter orange peel extract on the shelf-life of the common carp fillets during 16 days of refrigerated storage. Common carp fillets were treated with bitter orange peel extract (0.5 and 1% w/w), liposomal encapsulated bitter orange peel extract (0.5 and 1% w/w) and beta-hydroxytoluene (BHT, 100 and 200 ppm); their quality changes in terms of total volatile basic nitrogen (TVB-N), free fatty acid (FFA) peroxide value (PV), thiobarbituric acid (TBA) and sensory characteristics were investigated. Results showed that the encapsulated and pure extract and BHT could reduce chemical deterioration and lipid oxidation in the fillets compared to the control, as reflected with lower TVBN, FFA, PV and TBA values. Furthermore, common carp fillets treated with high concentration (1%) of the encapsulated bitter orange peel extract showed the lowest amount of lipid oxidation during the storage period compared with the others without any undesirable changes in sensorial attributes.
