Interpretive Summary:

Technical Abstract: Lipid has long been recognized as an important dietary component. Dietary lipid (fat) is a critical source of metabolic energy and a substrate for the synthesis of metabolically active compounds (essential fatty acids), and serves as a carrier for other nutrients such as the fat-soluble vitamins A, D, E, and K and vitamin precursors. The bioavailability of dietary lipid-soluble compounds is dependent on fat absorption. With the exception of essential fatty acids, phytosterols and fat-soluble vitamins, humans have the capacity to synthesize lipids from carbohydrate and protein. In the body, lipid serves as a critical component of cell membranes, as structural moieties of lipoprotein particles, and as a precursor for bioactive compounds involved in a wide range of biological functions.
