Animal fat is a solid or semi-solid lipid product extracted from animal adipose tissue, such as lard, butter and sheep oil. Animal fat contains a lot of saturated fatty acids and cholesterol, which is not only difficult to digest, but also easy to accumulate in human blood vessels, thus leading to gastrointestinal dysfunction and various cardiovascular and cerebrovascular diseases, seriously endangering human health and shortening life span. In addition to animal fat, you should also eat less or not eat animal fat foods, such as pig skin, pig brain, pork loin, bovine bone marrow, whole milk and so on.
Butter includes animal cream and vegetable cream. Among them, animal cream is concentrated milk fat extracted from fresh milk. Cream is sweet and rich, and is loved by many people, especially girls. However, butter also contains a lot of saturated fatty acids and cholesterol, which is recognized as the "enemy of the cardiovascular system". Don't eat more even if it is delicious.
Although vegetable butter itself does not contain saturated fatty acids, it contains more trans fatty acids. After eating, it will increase the low-density lipoprotein cholesterol in the blood, destroy the lipid metabolism mechanism of the human body, and cause a greater risk of cardiovascular and cerebrovascular diseases than animal fat. Therefore, compared with animal cream, vegetable cream should not be eaten more.
