Discordances exist in epidemiological studies regarding the association between the intake of nutrients and death and disease. We evaluated the social and health profile of persons who consumed olive oil in a prospective population cohort investigation (Pizarra study) with a 6-year follow-up. A food frequency questionnaire and a 7 d quantitative questionnaire were administered to 538 persons. T...

There is a continuing need for improved methods for assessing the adulteration of foodstuffs. We report some highly encouraging data, where we have developed direct infusion electrospray ionisation mass spectrometry (ESI-MS) together with chemometrics as a novel, rapid (1 min per sample) and powerful technique to elucidate key metabolite differences in vegetable and nut oils. Principal componen...

This study was carried outto investigate the effect of ultrasound-assisted extraction (UAE) on polyphenols from olive pomace with methanol (80%) as an extracting medium and studythe effects of addingthe extract to refined sunflower oilduring accelerated oxidationconditions. Ahigh amount of polyphenols was extracted from the olive pomace with a solvent-to-solid ratio of 40 at 50% of the maximum ...

OBJECTIVE We investigated the effects of dietary intervention with canola or olive oil in comparison with commonly used refined oil in Asian Indians with nonalcoholic fatty liver disease (NAFLD). SUBJECTS AND METHODS This was a 6-month intervention study including 93 males with NAFLD, matched for age and body mass index (BMI). Subjects were randomized into three groups to receive olive oil (n...

CHD is a leading cause of death and disability worldwide. Remarkably, CHD is largely preventable, as unhealthy lifestyles (smoking, lack of exercise and poor dietary habits) contribute to nearly 80 % of population-attributable risk. Among these lifestyle components, diet has been well studied. After decades of epidemiological, clinical and experimental research, an impressive body of scientific...

ABSTRACT: In this study, an analytical method is developed to determine 15 polycyclic aromatic hydrocarbons (PAHs) in olive and refined pomace olive oils using HPLC coupled with a fluorescence detector. The standardised method of ultrasound-assisted solvent extraction consisted of liquid–liquid extraction with organic solvent and purification on C18 and Florisil bonded-phase cartridges was modi...

BACKGROUND Diabetic state potentiates atherosclerosis and the type of edible oil consumed by the individual may affect this further. This study aimed to determine if the common edible oils in Nigeria have any effects on the lipid profiles and arteries of alloxan-induced diabetic male Wistar rats. METHODS Thirty male Wistar rats were randomly divided into five groups of normal control, diabeti...

Background: Butter is known to have a cholesterol-raising effect and, therefore, has often been included as a negative control in dietary studies, whereas the effect of moderate butter intake has not been elucidated to our knowledge. Objective: We compared the effects of moderate butter intake, moderate olive oil intake, or a habitual diet on blood lipids, highsensitivity C-reactive protein (hs...
