Cooking oils are an integral part of food preparation all over the world. Cooking completely without using any type of oil is an absolute no for most people from any part of the world. Traditionally, people from different parts of the world choose different types of oil for cooking. Olive oil, Canola oil, Sunflower oil, Coconut oil, Butter, Margarine etc are used by people from different parts of the world for cooking. In many communities, the choice of a cooking oil is part of the community tradition. They have been using that particular variety of oil forever they can remember! Here we are looking at the difference between these oils as far as our health is concerned.
Basically all oils are fat. By definition, fat is not healthy for you. Are they all unhealthy? All fats are not the same. Fats can be divided in to four categories. Saturated fats, Trans fats, Monounsaturated fats and Polyunsaturated fats. Of this, saturated fats and trans fats are considered as bad fats and are unhealthy for your body. Monounsaturated fats and Polyunsaturated fats are considered as good fats. The bad fats are responsible for increasing bad cholesterol and reducing good cholesterol in our body. Good fats does the opposite; increase good cholesterol and decrease bad cholesterol. Thus, in order to stay healthy, your cooking oil must have a very high percentage of good fats and very low percentage of bad fats in it.
Based on this condition, the best cooking oils available for you are canola oil, peanut oil, olive oil, sunflower oil, corn oil etc. The worst cooking oils available for you are hard margarine, butter, palm oil, coconut oil etc. Out of this, coconut oil is considered to be the worst and contains a higher percentage of bad fats than even animal fats!
If you use cooking oil sparingly, any of these oils can get the job done for you. Heavy use of any oil is not recommended. This applies for even heart healthy oils.
Another category of difference you will find in olive oil, coconut oil etc is extra virgin and refined. Extra virgin olive oil is gained from the first pressing of the olives and is done physically without the use of any chemicals at all. Refined olive oil is gained by using chemicals to preserve it and to neutralize any unpleasant taste or smell associated with it. As extra virgin ones contain natural ingredients and no chemicals, they are best for your health. Refined cooking oils can be much lighter in nature and may contain preservatives or chemicals. Thus, this can be harmful for your health.
Refined cooking oil will be free of smell, color etc and this is a reason why millions of Americans choose it. But that need not be the case always. Oil can have a color too. A good cooking oil can have a smell as well. In fact, natural oils with its own flavor and color are a lot better for your health than highly refined, bland, colorless, odorless cooking oils.
