What is PUFA?

PUFA in simple terms is called polyunsaturated fat that is obtained from vegetable oils and plant sources. It is one of the important forms of dietary fat essential for the body.

Most vegetable oils are low in PUFA, while animal fats are a mix of monounsaturated, saturated and polyunsaturated fats. Here is how to choose the right cooking oil for you.
