QUINONES, M.; MIGUEL, M.  e  ALEIXANDRE, A.. The polyphenols, naturally occurring compounds with beneficial effects on cardiovascular disease. Nutr. Hosp. [online]. 2012, vol.27, n.1, pp.76-89. ISSN 1699-5198.

In recent years, a number of studies have endorsed the beneficial effects of polyphenols intake on health, especially on the cardiovascular system. This is important since cardiovascular diseases are the main death cause worldwide. The effects of polyphenols are mainly due to their antioxidant properties. These compounds present vasodilating effects, and they can improve the lipid profile and lessen the oxidation of low-density lipoproteins (LDL). They show clear antiinflammatory effects and they can modulate the apoptotic pathways in the vascular endothelium. This review defines from the structural viewpoint the different groups of polyphenols that may occur in vegetables, and updates the knowledge on their bioavailability. Some of the recent studies establishing their beneficial properties at a cardiovascular level are also included.
