Walnuts and serum lipids.
Tree nuts and their importance in the prevention of coronary disease.
Substitution of saturated with monounsaturated fat in a 4-week diet affects body weight and composition of overweight and obese men.
A randomised crossover study of eight overweight or obese men (aged 24-49 years; BMI 25.5-31.3 kg/m(2)); who followed two diets for 4 weeks each; was performed to determine whether substitution of saturated fat with monounsaturated fat affects body weight and composition. Subjects were provided with all food and beverages as modules (selected ad libitum) of […]
A monounsaturated fatty acid-rich pecan enriched diet favorably alters the serum lipid profile of healthy men and women.
Frequent consumption of nuts is associated with decreased risk of cardiovascular disease. We investigated the effect of pecans rich in monounsaturated fat as an alternative to the Step 1 diet in modifying serum lipids and lipoproteins in men and women with normal to moderately high serum cholesterol. In a single-blind; randomized; controlled; crossover feeding study; […]
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 […]
Vitamin E consumption and the risk of coronary heart disease in men.
BACKGROUND. The oxidative modification of low-density lipoproteins increases their incorporation into the arterial intima; an essential step in atherogenesis. Although dietary antioxidants; such as vitamin C; carotene; and vitamin E; have been hypothesized to prevent coronary heart disease; prospective epidemiologic data are sparse. METHODS. In 1986; 39;910 U.S. male health professionals 40 to 75 years […]
Folate and vitamin B6 from diet and supplements in relation to risk of coronary heart disease among women
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 […]
Fatty acid composition of nuts – implications for cardiovascular health.
It is well established that; due to their high content of saturated fatty acids (SFA); the intake of meat and meat products is strongly associated with elevated blood cholesterol concentrations and an increased risk of hypertension; diabetes and cardiovascular diseases. Conversely; the intake of foods rich in unsaturated fatty acids; such as those contained in […]
Effects of walnut consumption as part of a low-fat; low-cholesterol diet on serum cardiovascular risk factors
Serum components; such as lipoproteins; coagulation factors (factor VII; tissue plasminogen activator (tPA); plasminogen activator inhibitor-1 (PAI-1); fibrinogen); and homocysteine have been associated with cardiovascular disease. Dietary intervention with a low-fat; low-cholesterol diet has favorably influenced cardiovascular disease and certain food; specifically the consumption of nuts; has been associated with reduced cardiovascular risks. The effects […]
Walnut-enriched diet increases the association of LDL from hypercholesterolemic men with human HepG2 cells
In a randomized; cross-over feeding trial involving 10 men with polygenic hypercholesterolemia; a control; Mediterranean-type cholesterol-lowering diet; and a diet of similar composition in which walnuts replaced approximately 35% of energy from unsaturated fat; were given for 6 weeks each. Compared with the control diet; the walnut diet reduced serum total and LDL cholesterol by […]
