Explain Food lipids

It is either consumed in the form of "visible" fats, which have been separated from the original plant or animal sources, such as vegetable oil and butter, or as constituents of basic foods, such as milk, cheese and meat. This is referred to as 'invisible fat'. You already know that dietary lipids play an important role in nutrition. They supply calories and essential fatty acids, act as vitamin carriers and increase the palatability of food. The largest supply of vegetable oil comes from the seeds of soy bean, cottonseed, peanut and the oil-bearing trees of palm, coconut and olive.
