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 […]

Regular peanut consumption improves plasma lipid levels in healthy Ghanaians

Objective: To determine whether the daily intake of 2;092 kJ (500 kcal) from peanuts will improve the lipid profiles and diet quality of healthy Ghanaians. Design A 30-week; randomized; cross-over trial study was conducted with healthy adults. Method: There were three treatment arms: Treatment 1 (T1); subjects were provided 2;092 kJ/day (500 kcal/day) peanuts to […]

Relation of higher folate intake to lower risk of Alzheimer disease in the elderly

BACKGROUND: Higher intake of folate and vitamins B6 (pyridoxine hydrochloride) and B12 (cyanocobalamin) may decrease the risk of Alzheimer disease (AD) through the lowering of homocysteine levels. OBJECTIVE: To relate intake of folate and vitamins B6 and B12 to AD risk. DESIGN AND PATIENTS: We followed up 965 persons 65 years or older without dementia […]

Almonds and postprandial glycemia – a dose-response study

Almonds; together with other nuts; reduce serum cholesterol levels and may reduce the risk of coronary heart disease. There is much current interest in the relation of coronary heart disease to postprandial events. We have therefore assessed the effects of varying amounts of almonds on the postprandial blood glucose response to a carbohydrate meal. Our […]

Effect of chronic consumption of almonds on body weight in healthy humans

Small changes of diet may reduce CVD risk. One example is the inclusion of nuts. They are rich in fiber; unsaturated fatty acids and phytonutrients. However; their fat content and energy density raise concerns that chronic consumption will promote weight gain. Randomized intervention studies are required to evaluate whether this concern is well founded. This […]

Purification; crystallization and initial crystallographic characterization of brazil-nut allergen Ber e 2. Acta Crystallogr Sect F Struct Biol Cryst Commun

Peanut and tree-nut allergies have attracted considerable attention because of their frequency and their lifelong persistence. Brazil-nut (Bertholletia excelsa) allergies have been well documented and the 11S legumin-like seed storage protein Ber e 2 (excelsin) is one of the two known brazil-nut allergens. In this study; Ber e 2 was extracted from brazil-nut kernels and […]

Combined use of total metal content and size fractionation of metal biomolecules to determine the provenance of pine nuts (Pinus pinea)

Four essential elements (Mn; Ni; Zn; and Cu) and their molecular-size distribution patterns have been determined; for twenty four samples of pine nuts from eight areas in Spain and Portugal (Huelva; Cádiz; Badajoz; Cataluña; Castilla; Madrid; Faro; and Coimbra); by size-exclusion liquid chromatography (SEC) coupled on-line to UV and inductively coupled plasma mass spectrometric (ICP-MS) […]

Macadamia nut consumption modulates favourably risk factors for coronary artery disease in hypercholesterolemic subjects.

Macadamia nuts are rich source of monounsaturated fats (oleic and palmitoleic acids) and contain polyphenol compounds; therefore; their consumption can be expected to impart health benefits to humans. This study was conducted to examine the effects of consuming macadamia nuts in hypercholesterolemic male individuals on plasma biomarkers of oxidative stress; coagulation and inflammation. Seventeen hypercholesterolemic […]

An increase in dietary n-3 fatty acids decreases a marker of bone resorption in humans

Human; animal; and in vitro research indicates a beneficial effect of appropriate amounts of omega-3 (n-3) polyunsaturated fatty acids (PUFA) on bone health. This is the first controlled feeding study in humans to evaluate the effect of dietary plant-derived n-3 PUFA on bone turnover; assessed by serum concentrations of N-telopeptides (NTx) and bone-specific alkaline phosphatase […]
