Comparable efficacy of hydrogenated versus nonhydrogenated plant sterol esters on circulating cholesterol levels in humans

Research has determined that plant sterol esters are effective in maintaining healthful cholesterol levels. Studies using margarine containing sitostanol-ester and soybean oil sterol-ester showed that both were equally effective in decreasing low-density lipoprotein and blood total cholesterol levels. Neither of the two esters affected high-density lipoprotein cholesterol levels.
