While choosing cooking oil and other types of fats, try to select one that is healthier compared to the other.
So before choosing a bottle of cooking oil check the label. Always go for the one that contains mostly polyunsaturated or monounsaturated one. Sometimes you may find Omega-3, well that’s a good one select it.
Canola oil, Sesame oil, safflower oil, Sunflower oil are among good ones which contains mostly unsaturated fats compared to saturated fats.
Palm oil, coconut oil isn’t good cox mostly its saturated fats.
Another important fat is margarine which is made by the hydrogenation of vegetable oils using a nickel catalyst. Addition of hydrogen will result in transforming the oil into a saturated fat and increases melting point so becomes a solid and is spreadable. But this isn’t good for your health. So that’s why nowadays partial hydrogenation is done so some amount of unsaturation. This is known as soft margarine so aware of it as well.
The next question is butter or margarine which is better? Butter contains saturated fats and cholesterol, both can increases the bad cholesterol LDL. Soft margarine, the recent one contains unsaturation so can say its better than butter.
So know about your fats, and chemistry is there to make a difference…
