Are the advantages of the Mediterranean diet transferable to other populations? A cohort study in Melbourne; Australia

A prospective cohort study; involving 141 Anglo-Celts and 189 Greek-Australians of both sexes aged 70 years or more; was undertaken in Melbourne; Australia. The objective was to evaluate whether adherence to the principles of the Mediterranean diet affects survival of elderly people in developed non-Mediterranean countries. Diet was assessed using an extensive validated questionnaire on […]

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) […]

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; […]

Effects of folic acid supplementation on hearing in older adults: a randomized; controlled trial.

Background: Age-related hearing loss is a common chronic condition of elderly persons. Low folate status has been associated with poor hearing. Objective: To determine whether folic acid supplementation slows age-related hearing loss. Design: Double-blind; randomized; placebo-controlled trial conducted from September 2000 to December 2004. Setting: The Netherlands. Participants: 728 older men and women recruited from […]
