Almonds in the Diet simultaneously Improve Plasma Alpha-Tocopherol Concentrations and Reduce Plasma Lipids
The objective of this study was to assess the dose-response effect of almond intake on plasma and red blood cell tocopherol concentrations in healthy adults enrolled in a randomized; crossover feeding trial. Participants were 16 healthy men and women; aged 41+/-13 years. After a 2-week run-in period; participants were fed three diets for 4 weeks […]
Almonds decrease postprandial glycemia; insulinemia; and oxidative damage in healthy individuals.
Strategies that decrease postprandial glucose excursions; including digestive enzyme inhibition; and low glycemic index diets result in lower diabetes incidence and coronary heart disease (CHD) risk; possibly through lower postprandial oxidative damage to lipids and proteins. We therefore assessed the effect of decreasing postprandial glucose excursions on measures of oxidative damage. Fifteen healthy subjects ate […]
Effects of appetite; BMI; food form and flavor on mastication: almonds as a test food.
Objectives: To investigate the effects of appetitive sensations; body mass index (BMI) and physical/sensory properties of food (almonds) on masticatory indices and resultant pre-swallowing particle sizes.Subjects/Methods: Twelve lean (BMI=22.2+/-0.3) and 12 obese (BMI=34.3+/-0.6) adults. After collecting appetitive ratings; electromyographic recordings were used to assess participants' microstructure of eating for five almond products (raw; dry unsalted […]
Almonds lower blood cholesterol and LDL-cholesterol but not HDL-cholesterol or triglycerides in human subjects: results of a meta-analysis.
Identification and quantification of flavonol glycosides in almond seedcoats using MALDI-TOF MS.
Interest in the molecular composition of almonds is growing; due to their popularity in a wide variety of food formulations. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is a powerful new technique that can be used to rapidly identify and quantify possible bioactive compounds in these popular tree nuts. Four flavonol glycosides were identified […]
Variation in the flavonol glycoside composition of almond seedcoats as determined by MALDI-TOF Mass Spectrometry.
Seedcoats of 16 almond varieties were screened for flavonol glycosides by using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). Flavonol glycosides were extracted by a simple methanolic extraction followed by a quick cleanup procedure with a Sep-Pak C(18) cartridge. Each of the 16 seedcoat samples exhibited a unique composition. Four flavonol glycosides; isorhamnetin rutinoside; […]
Effect on body weight of a free 76 kilojoules (320 calorie) daily supplement of almonds for 6 months.
OBJECTIVE: Regular nut consumption is associated with lower rates of heart attack. However; as nuts are fatty foods; they may in theory lead to weight gain; although preliminary evidence has suggested otherwise. We tested the hypothesis that a free daily supplement (averaging 76 kJ) of almonds for six months; with no dietary advice; would not […]
Anatomy and cell wall poly-saccharides of almond (Prunus dulcis D.A. Webb) seeds.
The anatomy of Prunus dulcis was analyzed by applying several differential staining techniques and light microscopy. Prunus dulcis seed has a thin and structurally complex seed coat; with lignified cellulosic tissue. The embryo has two voluminous cotyledons. Cotyledon cells have a high number of protein and lipid bodies; some of which have phytin. The provascular […]
Role of cell walls in the bioaccessibility of lipids in almond seeds.
BACKGROUND: Certain nutrients and phytochemicals in almonds may confer protection against cardiovascular disease; but little is known about factors that influence their bioavailability. A crucial and relevant aspect is the amount of these dietary components available for absorption in the intestine; which is a concept referred to as bioaccessibility. OBJECTIVE: We investigated the role played […]
