There are patients in my family who are strict about oil. Broadly speaking, the fat and calorie supplement of lard is very nutritious, but it is suitable for the age of nutritional deficiency (only eating coarse grains). People eat a certain amount of fat every day. If they eat too much, they will form excess fat in the body, which will lead to endocrine disorders, cardiovascular and cerebrovascular diseases and so on. After a long time, I can tell you that now more than 90% people have too much fat, so everyone should have a balanced nutrition and eat less lard. ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
