Tree Nut and Peanut Consumption in Relation to Chronic and Metabolic Diseases Including Allergy
The New and Emerging Research session highlighted the emerging understanding of both the positive and negative effects of nuts consumption on health. The limited nature of both experimental and epidemiological evidence for positive relationship(s) between nut intake and health were noted. Study inconsistency and limitations; particularly survey methodology; were explored. Recent results from epidemiologic studies […]
In vivo and T Cell Cross-Reactivity between Walnut; Cashew and Peanut
Background: Examination of IgE cross-reactivity among nuts has been limited to in vitro experiments. Cross-reactivity studies of nuts at the T cell level are difficult to interpret because of the inability to determine which cellular responses are from a true sensitization and which are due to cross-reactivity. Using a mouse model in which the sensitizing […]
Suppression of implanted MDA-MB 231 human breast cancer growth in nude mice by dietary walnut
Walnuts contain components that may slow cancer growth including omega 3 fatty acids; phytosterols; polyphenols; carotenoids; and melatonin. A pilot study was performed to determine whether consumption of walnuts could affect growth of MDA-MB 231 human breast cancers implanted into nude mice. Tumor cells were injected into nude mice that were consuming an AIN-76A diet […]
Consumption of restructured meat products with added walnuts has a cholesterol-lowering effect in subjects at high cardiovascular risk: a randomized; crossover; placebo-controlled study
BACKGROUND: Diet and lifestyle are modifiable factors involved in the development and prevention of non-communicable diseases; including cardiovascular disease. Nut consumption; particularly walnut intake; has been inversely related to incident coronary heart disease (CHD) in observational studies and to improved lipid profiles in short-term feeding trials. OBJECTIVE: To assess the potential functional effect associated with […]
Impact of Peanuts and Tree Nuts on Body Weight and Healthy Weight Loss in Adults
Nuts (ground and tree) are rich sources of multiple nutrients and their consumption is associated with health benefits; including reduced cardiovascular disease risk. This has prompted recommendations to increase their consumption. However; they are also high in fat (albeit largely unsaturated) and are energy dense. The associations between these properties; positive energy balance; and body […]
The Role of Tree Nuts and Peanuts in the Prevention of Coronary Heart Disease: Multiple Potential Mechanisms
Epidemiologic and clinical trial evidence has demonstrated consistent benefits of nut and peanut consumption on coronary heart disease (CHD) risk and associated risk factors. The epidemiologic studies have reported various endpoints; including fatal CHD; total CHD death; total CHD; and nonfatal myocardial infarct. A pooled analysis of 4 U.S. epidemiologic studies showed that subjects in […]
Possible Benefit of Nuts in Type 2 Diabetes
Nuts; including peanuts; are now recognized as having the potential to improve the blood lipid profile and; in cohort studies; nut consumption has been associated with a reduced risk of coronary heart disease (CHD). More recently; interest has grown in the potential value of including nuts in the diets of individuals with diabetes. Data from […]
Tree Nuts and Peanuts as Components of a Healthy Diet
Nuts have been part of the diet for thousands of years. In 2003; a Qualified Health Claim was approved; stating that eating 1.5 oz (42 g) of nuts per day may reduce the risk of heart disease. Usual intakes fall short of this recommendation. About one-third of Americans report consuming nuts (tree nuts or peanuts) […]
Oxidative Stability of Tree Nut Oils
The oxidative stability of selected tree nut oils was examined. The oils of almond; Brazil nut; hazelnut; pecan; pine nut; pistachio; and walnut were extracted using two solvent extraction systems; namely; hexane and chloroform/methanol. The chloroform/methanol system afforded a higher oil yield for each tree nut type examined (pine nut had the highest oil content; […]
Walnut Polyphenols Prevent Liver Damage Induced by Carbon Tetrachloride and d-Galactosamine: Hepatoprotective Hydrolyzable Tannins in the Kernel Pellicles of Walnut
The polyphenol-rich fraction (WP; 45% polyphenol) prepared from the kernel pellicles of walnuts was assessed for its hepatoprotective effect in mice. A single oral administration of WP (200 mg/kg) significantly suppressed serum glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) elevation in liver injury induced by carbon tetrachloride (CCl 4); while it did not […]
