Clinical Application of Plant Sterol and Stanol Products.
Plant sterols and stanols (PS) are natural, non-nutritive compounds that play important structural roles in plant membranes and abound in seeds and oils derived from them. Because they act within the intestinal lumen and undergo minimal absorption into the enterocytes, PS are non-systemic agents. Their physiological role in plants, natural origin, and non-systemic action, together with their proven capacity to lower serum total and LDL-cholesterol, make them quite attractive as non-pharmacological agents for the treatment of hypercholesterolemia. Recent meta-analyses have summarized the results of >100 randomized clinical trials and have clearly established that LDL-cholesterol is reduced by 9-12% with consumption of PS-fortified foods in different formats at doses of 2-3 g per day. PS are effective and safe cholesterol-lowering agents with many clinical applications: adjuncts to a healthy diet, common hypercholesterolemia, combination treatment with statins, metabolic syndrome, and diabetes. The cholesterol-lowering efficacy appears to be similar in all clinical situations. PS are also ideal agents to treat hypercholesterolemic children who are still not candidates to statin therapy or receive only low-dose statins. In the setting of statin treatment, the expected LDL-cholesterol reduction with PS is equivalent to up titrating twice the statin dose. There is not enough information on the efficacy of PS as add-on therapy to ezetimibe, fibrates, or bile acid binding resins. Attesting to the consistent scientific evidence on the cholesterol-lowering efficacy and safety of functional foods supplemented with PS, several national and international clinical societies have endorsed their use as adjuncts to a healthy diet.
