Abstract

Fitosterol ve fitastanoller, bitkisel yağlar, tohumlar ve sert kabuklu meyveler ile bazı meyve ve sebzelerde doğal olarak bulunan bileşiklerdir. Bunlar, güçlü kolestrol düşürücü ajanlardır. Çeşitli çalışmalar, fitosterol ve fitastanollerin günde 2-3 g tüketimiyle toplam kolesterolde % 8-17, LDL düşük yoğunluklu lipoprotein kolesterol seviyesinde % 9-20 oranında azalma olduğunu göstermiştir. Fitosterol ve fitastanoller, kolesterolun ince barsaktan absorpsiyonunu inhibe ederek toplam ve LDL kolesterolu düşürürler. Genel olarak, günlük diyetle 2-3 g fitosterol ve fitastanol almak zor olduğundan mayonez, margarin, yoğurt gibi çeşitli gıdalara ilave edilirler

PHYTOSTEROLS/PHYTOSTANOLS IN FOODS AND THEIR EFFECT ON HUMAN HEALTH

Abstract

Phytosterols and phytostanols are groups of compounds naturally present in vegetable oils, seeds, and nuts, and some fruits and vegetables. Phytosterols and phytostanols are potent hypocholesterolemic agents. Several studies have shown that a daily consumption of 2 to 3 g phytosterols or phytostanols reduce total serum cholesterol by 817% and low density lipoprotein LDL cholesterol by 920%. They decrease total serum and LDL-cholesterol levels in humans by inhibiting the absorption of cholesterol from small intestine. Because it is generally difficult to meet the daily recommended phytosterols/phytostanols of 2-3 grams, it is usually added in several foods such as mayonnaise, margarine, yoghurt.
