Maximizing Phenolics; Antioxidants and Sensory Acceptance of UV and Ultrasound Treated Peanuts

The effects of varying doses of UV and ultrasound (US); and incubation times at 25°C on total phenolics (TP); antioxidant capacity by two methods; trolox equivalent antioxidant capacity (TEAC) and oxygen radical absorbance capacity (ORAC) and sensory overall acceptance (OA) of treated peanuts were investigated. Optimum process parameters for UV and US were determined using […]

Effect of whole walnut and walnut-skin extracts on oxidant status in mice

OBJECTIVE: To evaluate the effect of the intake of whole walnuts and walnut fractions on the oxidant status in mice. METHODS: Thirty-six C57BL/6J male mice were randomized to be fed one of three diets: 1) a standard diet (control group); 2) a standard diet with 10% of whole walnuts (walnut-diet group); or 3) a standard […]

CONTEXT: Hyperhomocysteinemia is caused by genetic and lifestyle influences; including low intakes of folate and vitamin B6. However; prospective data relating intake of these vitamins to risk of coronary heart disease (CHD) are not available. OBJECTIVE: To examine intakes of folate and vitamin B6 in relation to the incidence of nonfatal myocardial infarction (MI) and […]

Beliefs; benefits; barriers; attitude; intake and knowledge about peanuts and tree nuts among WIC participants in eastern North Carolina

The objective of this study was to assess beliefs (e.g. advantages; disadvantages; benefits; barriers) and knowledge about eating peanuts and tree nuts. Personal interviews based on the Theory of Planned Behavior were conducted to elicit beliefs about eating nuts. Then; a cross-sectional survey was administered to WIC participants from one county in North Carolina. One-hundred-twenty-four […]

Effect of Brazil nut supplementation on the blood levels of selenium and glutathione peroxidase in hemodialysis patients

OBJECTIVE: In patients who have undergone hemodialysis; large amounts of reactive oxygen species (ROS) are produced and; at higher concentrations; ROS are thought to be involved in the pathogenesis of cardiovascular disease. It has been proposed that selenium (Se) may exert an antiatherogenic influence by reducing oxidative stress. The richest known food source of selenium […]

Protective effect of anacardic acids from cashew (Anacardium occidentale) on ethanol-induced gastric damage in mice

Cashew nut-shell liquid and the contained anacardic acids (AAs) have been shown to possess antioxidant; lipoxygenase inhibitory; anti-Helicobacter pylori and antitumor properties. Despite these known effects; hitherto there were no published reports on their likely gastroprotective effects. The present study was designed to verify whether AAs afford gastroprotection against the ethanol-induced gastric damage and to […]

Detection of hazelnuts and almonds using commercial ELISA test kits

Three commercial sandwich enzyme-linked immunosorbent assay (ELISA) test kits for the detection of hazelnuts and almonds were evaluated. Limits of detection and dynamic ranges were determined for hazelnuts and almonds spiked into cooked oatmeal; dipping chocolate; and muffins (baked). The limit of detection values varied from 1 to 38 mug/g; depending on the food matrix […]
