A video explainer on trans fatty acids or TFAs.
Our body requires only two kinds of ‘healthy’ fats – monounsaturated and polyunsaturated. They are a major source of energy. The kind that is harmful to our body is known as trans fatty acids or TFAs.

This is done to make them more solid, increase their shelf life, and for use as an adulterant as they are cheap.
