In this article, we will compare two mostly used oils and let you know which of these two is better.

Due to sufficient quantity of polyunsaturated fatty acids, corn oil is a lot helpful in lowering the blood pressure.

About 10% of blood pressure is controlled by these fatty acids present in this oil.(6,7)

The users should be careful about the excessive intake of this oil.
