Three Mistakes in Drinking Milk: Even if you drink it, you will drink it in vain

　　1. Milk must be boiled?

　　Generally, the temperature requirements for milk sterilization are not high. It takes 3 minutes at 70°C and 6 minutes at 60°C. If it is boiled and the temperature reaches 100°C, the lactose in the milk will caramelize, and caramel can induce cancer . Secondly, after boiling, the calcium in the milk will precipitate with phosphate, thereby reducing the nutritional value of the milk.

　　2. Is it okay to add rice soup or porridge to milk?

　　Some parents believe that doing so can make nutrition complementary. In fact, this approach is very unscientific. Milk contains vitamin A, while rice soup and porridge are mainly starch. They contain lipoxygenase, which will destroy vitamin A. If children, especially infants and young children, do not absorb enough vitamin A, their development will be delayed and they will become frail and sickly. Therefore, even if it is to supplement nutrition, the two should be eaten separately.

　　3. Can bottled milk be left in the sun?

　　Some parents learned from advertisements that vitamin D is also needed to supplement calcium, and spending more time in the sun is a good way to absorb vitamin D, so they followed the prescription and put the bottled milk in the sun. In fact, this is not worth the gain. You may gain some vitamin D from milk, but lose vitamin B1, vitamin B2 and vitamin C. Because these three major nutrients will decompose in the sun, causing some or all of them to be lost. ； Moreover, lactose will ferment in the sun, causing milk to deteriorate.
