Every day we consume approximately 300mg of cholesterol and its esters and 100g of triglyceride in our diet.1 This mixes in the intestinal lumen with about 900mg of biliary cholesterol and thereafter the total package is reduced by digestion to free cholesterol, fatty acids and mono- and diglycerides which become incorporated, through the detergent effects of bile acids, into water soluble micellesfor transport to absorption sites on the luminal surfaces of small intestinal enterocytes (Fig. 1). Triglyceride absorption is virtually complete whereas only about 50% of the cholesterol finds its way into the intestinal mucosa, the remainder being lost in the faeces. Within the enterocyte, cholesteryl esters are rapidly reconstructed by the action of the enzyme acyl Coenzyme A cholesterol acyltransferase (ACAT) and incorporated, with triglyceride, into large lipid-rich chylomicron particles containing about 1% protein. These appear in abundance
