  • Phytosterols

    Phytosterols are compounds that have a structure like cholesterol and are found naturally in small amounts in foods such as vegetable oils, fruits, legumes and nuts. When consumed regularly in concentrated products such as phytosterol-containing margarines, they can help to lower cholesterol levels by reducing cholesterol absorption.

  • Prebiotic

    A prebiotic is a substance that promotes the growth of the beneficial bacteria in the intestine. Prebiotics work by providing food for the intestinal bacteria. Examples of prebiotics are inulin and fructooligosaccharides.
