It's hot now, so will the children eat more milk?

A new study shows that exercise may play a more important role in keeping children's bones healthy than drinking a lot of milk.

Researchers pointed out in a report that for children, it is not that the more milk they drink, the better their bones develop. They stressed that exercise and eating some foods rich in calcium, such as tofu, can play a good role in bone development. According to the report published in Pediatrics, increasing the consumption of milk or other dairy products is not the best way to provide enough calcium for the body. There are many other ways to get easily absorbed calcium, such as drinking a cup of orange juice with vitamins, a cup of soy milk, a cup of boiled cabbage juice, two packs of instant oatmeal or eating half a bowl of tofu and half a bowl of broccoli.

Researchers from the Washington Committee of Responsible Doctors, a non-profit organization, studied 37 studies on the effect of calcium absorption on the bone strength of children over 7 years old, and found that 27 of them did not support the view that drinking more milk could increase calcium. Other 10 research results also show that drinking too much milk has little effect on bone health, or because vitamin D or other ingredients are added to milk, it is impossible to correctly judge whether drinking too much milk is effective or vitamin ingredients are effective.

Ameera Nuo, a nutritionist who led the study, said: "According to the previous nutrition theory, insisting on drinking milk or dairy products can improve the bone mineral absorption of children and adolescents. However, the existing evidence does not support this view. " By examining bone density and fracture probability, the researchers found that physical exercise played a more important role in increasing calcium absorption, which can make bones stronger.

Frank Greener, a pediatrician at the University of Wisconsin-Madison, commented that the ideal way to make bones grow healthily is to let children exercise more and ensure that they consume1300mg of calcium every day. He also said that the easiest way to get calcium is to drink low-fat dairy products, which also contain other nutrients, such as vitamin D, which are usually difficult to obtain from other dietary sources.
