A certain amount of fat is also necessary. This can be had in the form of ghee or oil. If ghee can be had, oil becomes unnecessary. It is difficult to digest and is not so nourishing as pure ghee . An ounce and half of ghee per head per day, should be considered ample to supply the needs of the body.
Whole milk is also a source of ghee.
Those who cannot afford it should take enough oil to supply the need for fat. Among oils, sweet oil, cocoa-nut oil, and ground nut oil should be given preference. Oil must be fresh. If available, it is better to use hand-pressed oil. Oil and ghee sold in the bazaar are generally quiet useless.
