Purpose Coffee is rich in compounds such as polyphenols, caffeine, diterpenes, melanoidins and trigonelline, which can stimulate brain activity. Therefore, the possible association of coffee consumption with cognition is of considerable research interest. In this paper, we assess the association of coffee consumption and total dietary caffeine inta...

Pulses such as peas, beans or lentils are one of the most complete foods at the nutritional level; however, they are one of the most often neglected foods in the diets of university students. Entrance to university translates into a major lifestyle change for many young people, and the habits acquired or cemented at this time will remain into adult...

Introduction and objectives Metabolic syndrome (MetS) is a combination of various cardiovascular risk factors with a major impact on morbidity and premature mortality.

Dietary guidelines universally advise adherence to plant-based diets. Plant-based foods confer considerable health benefits, partly attributable to their abundant micronutrient (e.g., polyphenol) content. Interest in polyphenols is largely focused on the contribution of their antioxidant activity to the prevention of various disorders, including ca...

Background & aims: Few studies have compared micronutrient intake and fulfilment of average requirements (EAR) in non-diabetic, pre-diabetic and diabetic adults at high cardiovascular risk. We assessed these variables in a large sample of participants in the PREDIMED-PLUS randomized trial of primary cardiovascular prevention with diet and physical...

Hypertension is one of the most important risk factors associated with the development of cardiovascular diseases. Numerous studies have revealed that a diet enriched in olive oil can have a beneficial effect on blood pressure. This systematic review includes the effects of olive oil on blood pressure in individuals without previous cardiovascular...

In this review the usual methods applied in systematic reviews and meta-analyses are outlined. The ideal hypothesis for a systematic review should be generated by information not used later in meta-analyses. The selection of studies involves searching in web repertories, and more than one should be consulted. A manual search in the references of ar...
