Plant sterols and their derivatives: The current spread of results

Whereas the cholesterol-lowering action of plant sterols and their derivati ves has been well established, more recent results have produced new inform ation concerning the similar effects of various mixtures and dose-response relationships. Moreover, although these materials have generally been viewe d as safe for long-term use in almost all sectors of the population, some c oncerns remain regarding the impact of phytosterol consumption on other lip id-soluble nutrients, which need to be further addressed. Further work: is also required to define the relationship between plant sterol consumption, circulating sterol levels, and risk of certain cancers.
