Plant sterols for adults with hypercholesterolemia treated with or without medication (statins)

Hypercholesterolemia is the most common coronary risk factor among the Spanish population; 37.4% of the Spanish adult population have cholesterol levels between 190 and 240 mg/dl. Foods enriched with plant sterols (PS) can effectively reduce plasma cholesterol in patients with high levels. However, its effectiveness and safety in adults with moderate hypercholesterolemia who are on medication (statins) or not has been less studied. The aim of this review is to establish the possible role of plant sterols in the control of hypercholesterolemia, as well as how safe they are for people with moderate hypercholesterolemia treated with statins. The main studies were looked at, regardless of design, language or publication date which studied the connection between plant sterols and hypercholesterolemia, using Pubmed/Medline, SCOPUS and Google Scholar databases. The studies brought together in this review show that an intake of between 2 and 3g/day of plant sterols effectively reduces plasma cholesterol levels in patients with hypercholesterolemia. Both clinical studies and available meta-analyses do not indicate any problems related to the drug-nutrient interaction associated with the use of plant sterol-enriched foods. In patients with moderate hypercholesterolemia where the use of statins is not justified a healthy diet, exercise and foods high in PS can provide the best therapeutic approach.
