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 […]
Second International Nuts and Health Symposium; 2007: Introduction
Biochemical Characterization of Soluble Proteins in Pecan [Carya illinoinensis (Wangenh.) K. Koch]
Pecans (cv. Desirable) contained approximately 10% protein on a dry weight basis. The minimum nitrogen solubility (5.9-7.5%) at 0.25-0.75 M trichloroacetic acid represented the nonprotein nitrogen. Among the solvents assessed for protein solubilization; 0.1 M NaOH was the most effective; while borate saline buffer (pH 8.45) was judged to be optimal for protein solubilization. The […]
Formation of Lipid Oxidation and Isomerization Products during Processing of Nuts and Sesame Seeds
The aim of the present study was to quantify some nutritional and safety quality parameter changes that take place in nuts (roasting) and sesame seeds (dehulling; roasting; milling; and sterilization) during processing. Such evaluation was based on chemical analysis of various indicators of lipid alteration in raw and processed pistachios; almonds; peanuts; and tahina. Lipid […]
Antioxidant properties of dried plum ingredients in raw and precooked pork sausage
Raw pork sausages with no antioxidant (control); 3% or 6% dried plum puree (DP); 3% or 6% dried plum and apple puree (DPA); or 0.02% butylated hydroxytoluene and butylated hydroxyanisole (BHA/BHT) were (1) stored raw in chubs at 4 degrees C (RR) and evaluated weekly over 28 d; (2) cooked as patties; vacuum packaged; and […]
Aspergillus nomius; an important aflatoxin producer in Brazil nuts?
The relation between aflatoxin B1 and G1 was examined in samples from 199 aflatoxin contaminated lots of in-shell Brazil nut imported to Europe. In most of the samples; the relation between B1 and G1 were approximately 50/50 indicating that the major responsible aflatoxin producing fungi cannot be Aspergillus flavus; which produces solely B aflatoxins. Fungal […]
Growth of aflatoxigenic moulds and aflatoxin formation in Brazil nuts
The present study aimed at gaining more knowledge of the growth of aflatoxigenic moulds and aflatoxin production in Brazil nuts in relation to humidity conditions and storage time. For this purpose; the growth of aflatoxigenic moulds and the increase in aflatoxin levels in Brazil nuts was studied in the laboratory at temperature and humidity conditions […]
Characterization of Aspergillus flavus strains from Brazilian Brazil nuts and cashew by RAPD and ribosomal DNA analysis
Aims: The aim of this study was to determine the genetic variability in Aspergillus flavus populations from Brazil nut and cashew and develop a polymerase chain reaction (PCR) detection method. Methods and Results: Chomatography analysis of 48 isolates identified 36 as aflatoxigenic (75%). One hundred and forty-one DNA bands were generated with 11 random amplified […]
