In medical theory, lard belongs to animal fat, unlike soybean oil, which belongs to unsaturated vegetable oil. Long-term consumption may be harmful to blood lipids and cardiovascular system. The high content of saturated fatty acids in lard will increase the content of cholesterol (LDLC), which will lead to arteriosclerosis and directly lead to hypertension, heart disease and cerebral hemorrhage. At the same time, we generally do not lack animal fat in our daily diet, and it is recommended not to consume too much lard. ?
In the past, life was difficult and material was scarce. Eating lard can supplement the deficiency of oil intake, but it is not necessary now.
