Plant stanol ester

Plant stanol ester is a substance derived from plant sterols, which are naturally found in small amounts in fruits, vegetables, nuts, seeds, and cereals. The sterols are extracted and then chemically modified to form esters, which are more easily incorporated into foods.

Plant stanol ester is added to foods to help reduce cholesterol absorption. It is most commonly found in spreads, yogurts, and dairy drinks, where it functions as a functional ingredient to provide a health benefit. Manufacturers add it to products that consumers might eat regularly as part of a balanced diet.

Plant stanol ester is not a food additive and does not have an E-number. It is recognised for its cholesterol-lowering properties. Scientific bodies like the European Food Safety Authority (EFSA) have evaluated the evidence for plant sterols and stanols and concluded that they can help lower blood cholesterol. The NHS advises that consuming 1.5–2.4 g of plant sterols or stanols per day can help lower blood cholesterol. Evidence suggests that these effects are achieved at typical consumption levels in foods fortified with plant stanol ester. No significant controversies exist regarding its use.
