摘要:Since the 1950s and 1970s, plant sterols and plant stanols have been known to partly block the uptake of cholesterol and to significantly lower serum cholesterol concentrations. In the 1990s, it became possible to introduce foods enriched with plant stanols to consumers. This esterified form of plant stanols made it possible to incorporate significant amounts of plant stanols into everyday foods. By now, the efficacy and safety of plant stanol esters has been verified in more than 50 published clinical trials.
