Numerous recent studies have indicated possible roles for free-radical-mediated processes in human pathology. This has led to a great interest in the substances thought to prevent the deleterious effects of these substances in vivo, the antioxidants. The biochemistry of free-radical reactions, the manner in which they damage cells and the antioxidants inhibiting their reaction with cellular con...

Phytochemicals may protect cellular DNA by direct antioxidant effect or modulation of the DNA repair activity. We investigated the repair activity towards oxidised DNA in human mononuclear blood cells (MNBC) in two placebo-controlled antioxidant intervention studies as follows: (1) well-nourished subjects who ingested 600 g fruits and vegetables, or tablets containing the equivalent amount of v...

Resveratrol and its dimethoxylated derivative, pterostilbene, are produced by several plant species, including a few edible crops such as peanut (Arachis hypogaea L.), grapes (Vitis spp.), blueberries (Vaccinium well some plants used in traditional medicine. Both compounds inducible, antimicrobial with activity against both pathogenic bacteria fungi, an apparently not directly related to their ...

Unhealthy dietary patterns are associated with poor lung function. It is not known whether this is due to low consumption of antioxidant-rich fruit and vegetables, or is a consequence of higher intakes of harmful dietary constituents, such as processed meat. We examined the individual and combined associations of processed meat, fruit and vegetable consumption and dietary total antioxidant capa...

An 8-week feeding trial was carried out with juvenile yellow catfish to study the effects of dietary available phosphorus (P) on growth performance, body composition, and hepatic antioxidant property. Six pellet diets were formulated to contain graded available P levels at 0.33, 0.56, 0.81, 1.15, 1.31, and 1.57% of dry matter, respectively. Triplicate tanks with each tank containing 60 juvenile...

This study was designed to investigate the in vitro and in vivo antioxidant activities of inulin. The in vitro assays demonstrated that the antioxidant activities of inulin, including the DPPH radical scavenging activity, ABTS scavenging activity and ferric reducing power, were weak and significantly lower than those of Vitamin C (P < 0.05). The influence of dietary supplementation with inulin ...

background: stroke is one of the leading causes of death and certainly the major cause of disability in the world. diet and nutrient has an effective role in prevention and control of the risk of stroke. the aim of this study was to review the studies on the relationship between dietary intake and stroke incidence. methods: in this study, the terms of “fat”, “cholesterol”, “antioxidant”, “vitam...

OBJECTIVE To validate a brief FFQ developed for capturing short-term antioxidant intake in a sample of US college students. DESIGN A seventy-four-item antioxidant FFQ was developed based on major antioxidant sources in the American diet. The FFQ was validated against 30 d food records (FR) and plasma antioxidant concentrations. The reliability of the FFQ was evaluated by two FFQ administered ...
