No, this is not true. In fact, although it is extracted from the corn grain germs which are high in carbohydrates, corn oil does not contain carbohydrates at all (0 g of carbs). Also, corn oil (which is commonly consumed) is one of the oils that are the richest in vitamin E. Also, it is rich in omega 6 but low in omega 3. It is a fluid oil of a light yellowish color, that is relatively odorless and of a mild flavor.
In addition, edible oils are vegetable oils that are intended for culinary use. Depending on their type, they can be used for seasoning and/or cooking or for frying. They are carbohydrate-free and are almost totally made of fat.
Since each type of oil has a fatty acid composition that differs from other oils and none of them has a particularly ideal nutritional composition, it is always necessary for us to vary the types of oil we consume and alternate between them so that to guarantee a good balance between the various types of fatty acids and thus to be able to take full advantage of the excellent antioxidant virtues that some of them possess.
