Fat mixtures enriched with triglycerides having long, saturated, preferably C16 to C22, fatty acid residues and short, preferably C2 to C4, acid residues are employed in edible compositions as low calorie fats. The preferred embodiments comprise mixtures of at least two triglycerides bearing long residues (e.g. stearyl) and short residues (e.g. acetyl or propyl). In one preferred embodiment, each triglyceride contains short chain residues which are different from those in the other triglyceride. In another preferred embodiment, at least a portion of the triglycerides have two different short residues. Methods of using the low calorie fats and food products incorporating them, particularly in coating, shortening and margarine products, are disclosed.
