The doctors also advised that cooking oil should not be heated till it starts emitting smoke as this leads to production of trans fats, considered unhealthy for the heart.
"Balanced oils including rice bran, mustard and olive oils are good for cooking. Blends or combinations of these oils can be a good option," said Professor Sundeep Mishra of the AIIMS cardiology department.
Balanced oils have less than 4 grams of saturated fat per tablespoon and no partially hydrogenated oils or trans fats.
He said repeated use of oil, especially for deep frying, is also bad for the heart because such oil content is mostly composed of trans fats, he said, citing the example of street food.
