Dietary intake and food sources of fatty acids in Australian adolescents

BACKGROUND: Dietary fat consumed during childhood and adolescence may be related to the development of cardiovascular and other chronic diseases in adulthood; however; there is a lack of information on specific fatty acid intakes and food sources in these populations. Our study aimed to assess fatty acid intakes in Australian adolescents; compare intakes with national […]

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 […]

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 […]

Effect of pistachio diet on lipid parameters; endothelial function; inflammation; and oxidative status: A prospective study

OBJECTIVE: Recent studies have suggested that nuts have favorable effects beyond lipid lowering. We aimed to investigate effect of the Antep pistachio (Pistacia vera L.) on blood glucose; lipid parameters; endothelial function; inflammation; and oxidation in healthy young men living in a controlled environment. METHODS: A Mediterranean diet was administered to normolipidemic 32 healthy young […]

Melatonin in walnuts: Influence on levels of melatonin and total antioxidant capacity of blood

OBJECTIVE: We investigated whether melatonin is present in walnuts (Juglans regia L.) and; if so; tested whether eating walnuts influences melatonin levels and the total antioxidant status of the blood. METHODS: Melatonin was extracted from walnuts and quantified by high-performance liquid chromatography. After feeding walnuts to rats; serum melatonin concentrations were measured using a radioimmunoassay […]
