Question

Impact of quality of dietary fat on serum cholesterol and coronary heart disease: ffocus on plant sterols and other non-glyceride components

Answer 1

Elevated serum low density lipoprotein (LDL) cholesterol is a strong risk factor for coronary heart disease; dietary as well as therapeutic regimens target reduction of serum LDL cholesterol to decrease the morbidity and mortality of coronary heart disease. The fatty acid composition of dietary fat has a marked impact on serum LDL cholesterol and other risk factors of diet-related chronic diseases (metabolic syndrome, diabetes and coronary heart disease). Besides fatty acids, which constitute > 95% of their content, fats in foods contain other fat-soluble chemicals collectively called non-glyceride components. Sterols are a major part of the non-glyceride components of fats in plant foods and get concentrated in vegetable oils.
