Which cooking oil is better to use corn oil or coconut oil and why?

Canola or olive oil are preferred. Try to avoid lard and saturated fats and incorporate good fat sources. Examples nclude avocado and salmon.

For cooking such as frying, coconut oil is better than corn oil because coconut oil is more stable in high temp so less antinutrient acrylamide, a highly reactive compound that has been linked to problems with nerve, hormone, and muscle function, is produced. Acrylamide has been classified as a potential carcinogen by the International Agency for Research on Cancer (IARC).
