Fats are predominantly triesters of fatty acids and glycerol – commonly known as triglycerides. Triglycerides that appear as solid at room temperature are normally called fats while those that are liquid are referred to as oils. Fat is a vital nutrient that provides the body with energy as well as acts as a source of essential fatty acids. Current dietary recommendations are that fats should supply no more than 30% of a person’s energy requirement. In terms of energy value a gram of fat yields 9 cal of energy compared to 6 cal/g for starch and proteins.
