Triglycerides are the main type of fat found in the diet and make up about 95% of the fat consumed. They consist of three fatty acids attached to a glycerol backbone and play a crucial role in energy storage and metabolism. When we consume dietary fats, they are primarily in the form of triglycerides, which our bodies then break down and utilize for energy or store for later use.

Phospholipids serve critical functions in cellular structure and signaling but are not the primary dietary fat. Cholesterol, while a significant component of cell membranes and a precursor for several hormones, does not constitute the primary form of dietary fat. Trans fats, which are created during hydrogenation and found in some processed foods, are a type of unsaturated fat but do not represent the main type of fat in the diet. Thus, triglycerides stand out as the predominant form of fat encountered in food and involved in energy processes.
