Differential effects of walnuts vs almonds on improving metabolic and endocrine parameters in PCOS.
Background/Objectives: Polycystic ovary syndrome (PCOS) is commonly associated with insulin resistance; dyslipidemia and increased inflammation; which all benefit from dietary intake of monounsaturated and n-3 polyunsaturated fatty acids (MUFA and n-3 PUFA). Our goal was to compare the effects of MUFA-rich almonds vs n-3/n-6 PUFA-rich walnuts on metabolic and endocrine parameters in PCOS. Subjects/Methods: Thirty-one […]
Determination of fatty acid composition of -irradiated hazelnuts; walnuts; almonds; and pistachios
Hazelnut; walnut; almonds and pistachio nuts were treated with 1; 3; 5; and 7 kGy of gamma irradiation. Oil content; free fatty acid; peroxide value and fatty acid composition of the nuts were investigated immediately after irradiation. The data obtained from the experiments indicated that gamma irradiation did not cause any significant change in the […]
Body mass interacts with fat quality to determine the postprandial lipoprotein response in healthy young adults
BACKGROUND AND AIMS: Postprandial lipemia predicts the evolution of cardiovascular disease. Obesity is associated with an increase in the magnitude of postprandial lipemia. Our objective was to evaluate the influence of body mass index (BMI) on the effects of acute ingestion of different types of fat on the postprandial lipemic response. METHODS AND RESULTS: Twenty-one […]

Effect of moderate walnut consumption on lipid profile; arterial stiffness and platelet activation in humans.
Background/Objectives: A large intake of walnuts may improve lipid profile and endothelial function. The effect of moderate walnut consumption is not known. We investigated whether a moderate intake of walnuts would affect lipid profile; arterial stiffness and platelet activation in healthy volunteers. Subjects/Methods: A total of 30 healthy males were recruited into a single-blind randomized […]
The effects of high walnut and cashew nut diets on the antioxidant status of subjects with metabolic syndrome.
Background Nut consumption is associated with a protective effect against coronary heart disease; partly due to its high antioxidant content. It is hypothesized that the inclusion of nuts in the diet will improve the antioxidant status of subjects with metabolic syndrome who may be vulnerable to impaired antioxidant status. Aim The effects of high cashew […]
Lifestyle Counseling and Supplementation with Flaxseed or Walnuts Influence the Management of Metabolic Syndrome
A healthy lifestyle may ameliorate metabolic syndrome (MetS); however; it remains unclear if incorporating nuts or seeds into lifestyle counseling (LC) has additional benefit. A 3-arm; randomized; controlled trial was conducted among 283 participants screened for MetS using the updated National Cholesterol Education Program Adult Treatment Panel III criteria for Asian Americans. Participants were assigned […]
Walnut (Juglans regia L.): genetic resources; chemistry; by-products
Walnut (Juglans regia L.) is the most widespread tree nut in the world. There is a great diversity of genotypes differing in forestry; productivity; physical and chemical nut traits. Some of them have been evaluated as promising and may serve as germplasm sources for breeding. The nutritional importance of the nut is related to the […]

Study on antioxidant activity of common dry fruits
This study investigates the antioxidant activity of different dry fruits (almonds; walnut; cashew nut; raisins and chironji) through several chemical and biochemical assays: reducing power; lipid peroxidation damage in biomembranes and determination of antioxidant enzymes activity (SOD and CAT). To estimate the total phenolic content; the assay using Folin-Ciocalteu reagent was used. The EC(50) values […]
