Useful properties and calorie content
Vegetable oils are the most important source of polyunsaturated fatty acids that are not synthesized by the human body. Linoleic and linolenic acids fight atherosclerosis - the most common cause of heart and vascular diseases, as well as cerebral circulation disorders. They are involved in the synthesis of structural components of cell membranes, which are responsible for the normal functioning of the latter and their resistance to damage. Polyunsaturated fatty acids accelerate the metabolism in the liver.
Phospholipids, which are part of vegetable oils, regulate fat metabolism, protect tissue cells and ensure their growth and reproduction. Vitamin A is a powerful antioxidant that increases the body's defenses. Vitamin E is considered the vitamin of youth and is essential for women to maintain their reproductive health. Vitamin D promotes the growth of teeth and bones.
The calorie content of vegetable oils varies from 800 to 990 Kcal per 100 g of product. Such high calorie values are compensated by the increased degree of absorption of the product and the complete breakdown of these calories. This factor significantly depends on the production method and the content of polyunsaturated fatty acids in the oil.
