Blueberry anthocyanins in health promotion: A metabolic overview

Abstract

Diet has gained scientific community attention due to the crucial role in health maintenance, but also in disease treatment, and essential in disease prevention. Several food and food components, particularly phenolic rich foods, have been investigated as they present themselves as putative functional foods. In the past decades, obesity has reached epidemic proportions and consequently, metabolic syndrome (a set of disorders as impaired glucose tolerance, insulin resistance, abdominal obesity, dyslipidemia and high blood pressure, which increase the risk of cardiovascular disease and diabetes) incidence is increasing worldwide at an alarming rate and this phenolic rich foods, specially berries have been investigated to their potential beneficial effect in this disorders. In the present work the chemistry of blueberries (BB) (fruits of some Vaccinium species) was summarised as well as the knowledge about bioavailability and biokinetic of anthocyanins from blueberries with particular emphasis on its implications in metabolic disorders.
