At the end of the dietary intervention the immp supplemented group had a significantly higher fecal bulk mass 35 p 0 05 and lower levels of fecal dihydrocholesterol 50 p 0 05 a product of bacterial metabolism. Dietary advice invariably stresses the importance of fat reduction yet fats have diverse roles in human nutrition. Most of the fat we consume in our diet is in the form of triacylglycerol 90 95 with cholesterol and phospholipids making up the bulk of the remainder. The role of lipids in food high energy source.

Fecal total neutral sterol and bile acid excretion remained unchanged. Conversely other domains representing the bulk of the membrane lipids and which probably contain the relatively lower melting point lipids undergo solidus phase formation at temperatures which reflect changes in the membrane lipid composition which are in turn a reflection of the nature of the dietary lipid intake.

The first and regulated step of fatty acid synthesis is catalyzed by acetyl coa carboxylase which produces malonyl co a. Fat rich foods naturally have a high caloric density. The bulk of dietary lipid is neutral fat or triglyceride composed of a glycerol backbone with each carbon linked to a fatty acid foodstuffs typically also contain phospholipids sterols like cholesterol and many minor lipids including fat soluble vitamins. The process of lipid metabolism synthesizes and degrades the lipid stores and produces the structural and functional lipids characteristic of individual tissues.
