UNLABELLED In the present study the effect of garlic, in a form more similar to how most people eat garlic, on lipid and antioxidant metabolism in rats was investigated. The antioxidant activity was determined by the efficacy to scavenge 2, 2'-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) derived radicals in garlic samples. The highest results(More)
Garlic (Allium sativum L.) is an essential part of Polish, Ukrainian, and Israeli cuisine. The aim of this investigation was to compare the changes in bioactive compounds, proteins, and antioxidant potentials in fresh Polish, Ukrainian, and Israeli garlic samples after subjection to cooking temperature. Dietary fiber and essential trace elements were(More)
The effective substances (polyphenols, phenolic and ascorbic acids, flavonoids and dietary fibers) and antioxidative activities, using different radical-scavenging tests, were determined for Jaffa sweeties and grapefruit. The antioxidative activities comprised the contributions from polyphenols, phenolic acids, flavonoids and ascorbate components, and were(More)
The aim of this study was to compare the hypocholesterolemic and antioxidant effects of two diets supplemented with dry persimmon in rats fed cholesterol (C). Three groups of male Wistar rats each of 13 animals during 4 weeks were fed different diets: the control group (CG)—semipurified diet with 1% of C and two experimental groups (EG1) and (EG2)—the same(More)
This article reviews the contemporary data concerning atherosclerosis and protecting properties of garlic. Recent advances in basic science have established a fundamental role for inflammation in mediating all stages of this disease from initiation through progression and, ultimately, the thrombotic complications of atherosclerosis. These new findings(More)
The purpose of this study was to compare the hypolipidemic and antioxidant e€ects of two diets in rats fed cholesterol (NOC). The experiment was performed on 3 groups of growing male Wistar rats. In each group there were 12 animals and during 4 weeks they were fed di€erent diets: the control group (CG) fed semipuri®ed diet with 1% of NOC, and two(More)
The aim of this study was to investigate the possibility to use the bioactive components from cape gooseberry (Physalis peruviana), blueberry (Vaccinium corymbosum), and cranberry (Vaccinium macrocarpon) extracts as a novel source against oxidation in food supplementation. The quantitative analysis of bioactive compounds (polyphenols, flavonoids, flavanols,(More)
Effects of short-term lyophilized beer (LB) consumption on normotensive (WKY) and hypertensive (SHR) rats are reported. It was found that LB contains high quantities of bioactive compounds and has a high antioxidant potential. The WKY and SHR rats were divided into four groups of 8, two experimental and two controls, which were named LBWKY and LBSHR and(More)
The influence of diets supplemented with mussels, from polluted (MPoll) and non-polluted (MNPoll) areas, on some atherosclerosis indices in rats fed cholesterol (Chol) were studied. According to the results of our investigation in vitro, mussels from polluted areas had higher contents of proteins, metals and antioxidant compounds, mostly phenolics and(More)
The aim of this investigation was to assess the nutritional and health properties of Mon Thong durian cultivar at different stages of ripening. The assessment was carried out in vitro and in vivo. The contents of dietary fibers, minerals and trace metals at different stages of ripening were comparable. Total polyphenols (mgGAE/100 g FW) and flavonoids (mg(More)
