Edible vegetable oils are used in food, both in cooking and as supplements. Oils and fats are concentrated sources of energy. Vegetable oils contain Polyunsaturated Fatty Acids (PUFA) like linoleic and linolenic acids which are needed to meet the requirements.
Unsaturated fats like safflower oil contain high level of PUFA, whereas groundnut oil contains moderate amount of PUFA.
Newer sources of edible oils are being explored, e.g., rice bran oil which has fatty acid composition similar to groundnut, which is an important edible oil source.
