Effects of Probiotics, Prebiotics, and Synbiotics on Hypercholesterolemia: A Review

Cholesterol plays a major role in human health. High cholesterol is a leading risk factor for human cardiovascular disease such as atherosclerosis, coronary heart disease, and stroke. Excess cholesterol in the bloodstream can form plaque in the artery walls. Hypercholesterolemia is a major risk factor for the development of atherosclerosis. A number of pharmacological and non-pharmacological (including dietary) approaches being employed to reduce the cholesterol level. Numerous drugs that lower serum cholesterol have been developed to treat hypercholesterolemic patients, the best example being the statins drugs (Atorvastatin, Simvastatin, Rosuvastatin, and Lovastatin). However, the undesirable side effects of these compounds were observed and have caused concern about their long term therapeutic use. Several studies have been reported that the consumption of fermented dairy products decreases serum cholesterol. Probiotics are live microorganisms that promote health benefits upon consumption, while prebiotics are nondigestible food ingredients that selectively stimulate the growth of beneficial microorganisms in the gastrointestinal tract. Probiotics and prebiotics have been suggested to reduce cholesterol via various mechanisms without any deleterious effect to the human health. This paper may throw some light to prove the ability of these synbiotics as a novel alternative or adjuvant to chemical drugs to help fight the hypercholesterolemic problem
