[:it]La malattia coronarica è una patologia cardiovascolare ed è tra le la principale causa di mortalità e disabilità in tutto il mondo dove le arterie del cuore vengono ostruite da depositi di colesterolo e coaguli di sangue. Molti casi di coronaropatia possono essere prevenuti affrontando diete e stili di vita salutari.
Negli ultimi anni grande risalto è stati dato al ruolo preventivo dei fitosteroli, composti lipidici presenti negli alimenti di origine vegetale come oli vegetali, noci, semi, cereali, legumi, frutta e verdura.
In un recente studio è stato dimostrato su 240 soggetti ipercolesterolemici sani, che il consumo di 3 g di steroli vegetali al giorno è efficace nell’abbassare significativamente le concentrazioni di colesterolo LDL in media del 7-12,5%. Sono stati valutati i lipidi del sangue e misurati i biomarcatori della disfunzione endoteliale e dell’infiammazione (proteina C reattiva, siero amiloide A, IL-6, IL-8, TNF-α e molecole di adsesione).
Diversi Organismi e Istituzioni, come le International and European Atherosclerosis Societies, raccomandano nelle loro linee guida sulla gestione dei lipidi ematici e del rischio di malattia coronarica il consumo di steroli vegetali.

Many cases of coronary artery disease can be prevented by addressing healthy diets and lifestyles.
In recent years great emphasis has been given to the preventive role of phytosterols, lipid compounds found in plant-based foods such as vegetable oils, nuts, seeds, cereals, legumes, fruits and vegetables.
In a recent study, out of 240 healthy hypercholesterolemic subjects, the consumption of 3 g of plant sterols per day was effective in significantly lowering LDL-cholesterol concentrations by an average of 7-12.5%. Blood lipids were evaluated and biomarkers of endothelial dysfunction and inflammation (C-reactive protein, serum amyloid A, IL-6, IL-8, TNF-α and soluble intercellular adhesion molecule-1) were measured.
Various organisms and institutions, such as International and European Atherosclerosis Societies, recommend the consumption of plant sterols in their guidelines as a way to lower elevated LDL-cholesterol concentration and reduce the risk of coronary heart disease.
