The role of plant sterols

Ask a question

Where are sterols found?

Plant sterols, also called phytosterols and are naturally found in many plants, in particular cereals, fruits and vegetables.
Sterols are not produced in the human body, thus, can only be be brought into the body through food.

A similarity with cholesterol

Sterols have a similar chemical structure to that of cholesterol
  • This similarity enables the sterols to mislead the body into limiting the passage of cholesterol from the intestine into the bloodstream.
  • In the small intestine, cholesterol and sterols are in competition over the absorption of cholesterol by the body.

Cholesterol absorption is limited

Plant sterols limit the absorption of cholesterol in the intestine, support its elimination and thus decrease cholesterol levels in the blood .
A greater quantity is evacuated from the body and a lesser quantity enters the bloodstream.
