Generally speaking, vegetable oil contains more essential fatty acids, while animal oil contains less and more saturated fatty acids. The digestibility of vegetable oil is higher than that of animal oil; The vitamins provided by various edible oils are different. Most vegetable oils are rich in vitamin E, and animal oils such as cod liver oil, cream and egg butter have higher contents of vitamin A and vitamin D, while pig, cow and sheep fats contain almost no vitamins. It can be seen that the nutritional value of animal oil and vegetable oil is different. But no matter what kind of edible oil is absorbed by the human body, it can produce the same amount of heat.
In daily life, eating meat oil or vegetable oil is not good for human health. Excessive consumption of animal oil may lead to obesity and hypertension, resulting in arterialization and coronary heart disease. Eating too much vegetable oil is also harmful. The main fatty acid in vegetable oil is unsaturated fatty acid, which is easy to form lipid peroxide in human body, thus forming free radicals. Free radicals are currently considered to be important substances causing aging and tumors. Most nutritionists believe that it is better to mix animal oil with vegetable oil than to eat it alone. The ratio of vegetable oil and animal oil in diet is 2: 1.
