Milk is the food that cow mothers breastfeed their babies, just like human mothers breastfeed their own children. First of all, the growth cycle of people and cattle is different, so the growth hormone contained in milk does not match with people, which will make children who drink milk grow taller easily, but osteoporosis will occur after the age of 30.
Secondly, milk contains a lot of animal protein and high fat, which will lay a huge hidden danger for hypertension, diabetes, cancer and obesity.
Although milk is rich in calcium, its harm far outweighs its benefits. It is suggested that friends who need calcium supplement should get more sunshine, exercise properly and increase beans.
