Elemental composition and chemical characteristics of five edible nuts (almond; Brazil; pecan; macadamia and walnut) consumed in Southern Africa.
The total elemental concentrations and proximate chemical composition of five different tree nuts; almond (Prunus dulcus); Brazil (Bertholletia excelsa); pecan (Carya pecan); macadamia (Macadamia integrifolia) and walnut (Juglans nigra) that are consumed in South African households were investigated. In addition; six physicochemical properties of the extracted nut oils; namely acid value; iodine value; saponification value; […]
Effect of geographic origin variety and storage on tocopherol concentrations in walnuts by HPLC
Blood cholesterol and walnut consumption: a cross-sectional survey in France
BACKGROUND: The preventive role of polyunsaturated fatty acids in cardiovascular disease has been recognized. We conducted a cross-sectional study to assess the association between walnut consumption (oil and kernel) as a source of polyunsaturated fatty acids and blood lipid levels. METHODS: Seven hundred ninety-three persons; males and females; ages 18-65 years; living in a walnut […]
Fatty acid profiles; tocopherol contents; and antioxidant activities of heartnut (Juglans ailanthifolia Var. cordiformis) and Persian walnut (Juglans regia L.).
The fatty acid and tocopherol compositions of three heartnut (Juglans ailanthifolia var. cordiformis) varieties (Imshu; Campbell CW1; and Campbell CW3) were examined and compared with those of two Persian walnut (Juglans regia L.) varieties (Combe and Lake). The major fatty acids found in heartnuts and walnuts were identified by gas chromatography as linoleic (18:2n-6); alpha-linolenic […]
Walnuts lower serum cholesterol in Japanese men and women in Japan.
Recent studies have shown that incorporating moderate quantities of walnuts into the recommended cholesterol-lowering diet in the U.S. decreased serum concentrations of total cholesterol in normal American men. To explore whether walnut consumption would also prove effective as part of the Japanese diet; we studied the effects of walnut consumption on serum lipids and blood […]
Serum lipid profiles in Japanese women and men during consumption of walnuts.
OBJECTIVE: To determine the serum cholesterol; apolipoproteins and LDL oxidizability in young Japanese women and men during walnut consumption and to evaluate its active principle. DESIGN: Experimental study with a randomized design. SUBJECTS: Twenty healthy women and 20 healthy men. INTERVENTIONS: Subjects were randomly assigned to consume each of two mixed natural diets for 4 […]
Structured Dietary Advice Incorporating Walnuts Achieves Optimal Fat and Energy Balance in Patients with Type 2 Diabetes Mellitus.
OBJECTIVE: A cardioprotective dietary fat profile is recommended for the treatment of type 2 diabetes. The clinical feasibility of advice strategies targeting specific fatty acid intakes and the extent to which they can be achieved by free-living populations needs to be tested. Walnuts; with high n-3 polyunsaturated fatty acid (PUFA) content; may help optimize fatty […]
The scientific evidence for a beneficial health relationship between walnuts and coronary heart disease in USA.
The author and four independent experts evaluated the intent and quality of scientific evidence for a potential beneficial health relationship between the intake of walnuts and the reduction and prevention of coronary heart disease. The report also addresses the supporting evidence for the health benefit of other tree nuts and selected legumes. Compared to most […]
Walnuts Reduce Aortic ET-1 mRNA Levels in Hamsters Fed a High-Fat; Atherogenic Diet. University of California; Davis;
Walnut consumption is associated with reduced coronary vascular disease (CVD) risk; however; the mechanisms responsible remain incompletely understood. Recent clinical studies suggested that these mechanisms involve non-plasma lipid-related effects on endothelial function. Male Golden Syrian hamsters (12 groups; n=10-15) were fed for 26 wk atherosclerotic; high-fat; hyperlipidemic diets with increasing concentrations of whole walnuts (61-150 […]
