The difference between animal oil and vegetable oil: mainly fatty acids. Animal oil is generally saturated fatty acid, and vegetable oil is generally unsaturated fatty acid. In animal oil, saturated fatty glycerides are easy to coagulate, and blood vessels are easy to harden and embolize. Unsaturated fatty acids in vegetable oil can lower blood cholesterol and protect patients with coronary heart disease; Vegetable oil contains higher essential fatty acids than animal oil, which is a good source of essential fatty acids, and essential fatty acids are extremely important for the growth and development of infants. The difference in digestibility, because the melting point of vegetable oil is lower than that of animal oil, the digestibility is higher.
