Fat is also known as lipid and is mainly present in food in a form called ‘triglycerides’. Butter and margarine, for example, are almost entirely made up of triglycerides. Triglycerides consist of glycerol and three ‘tri’ fatty acids. The fatty acids can be mainly ‘saturated’ as in butter or mainly ‘polyunsaturated’ as in some margarines see Figure There are also monounsaturated fatty acids, which occur in quantity in the triglyceride of olive oil and peanut oil. Food may contain other fats, such as cholesterol and phospholipids, in addition to triglycerides. Lecithin is a phospholipid, made up of glycerol, choline and fatty acids, which again may be mainly saturated or polyunsaturated see Chart 48 on lecithin. Fat is energy dense, having an Atwater factor of 9 kilocalories, or 37 kilojoules, per gram. Also, it does not mix with water, so that the food in which it is found tends to be more energy dense because of the relative lack of water. If it is a fat of plant origin, it may be associated with dietary fibre, giving bulk and reducing energy density, as, for example, with the cereal oats that are relatively high in fat for a cereal, but also relatively high in dietary fibre. If the fat is from animal sources, the energy density will be rather high, not only because of the fat and the low amount of water, but also because there is no dietary fibre.
