Who is Sun? What's her opinion on diet?
She is a very influential expert consultant in nutrition and food safety. I seem to have read some of her views on infant drinking water, which is very interesting. She suggested that the water that babies drink should contain a certain amount of minerals, especially zinc, but not the mineral water that adults usually drink. It was after reading her point of view that I gave the baby special water. My baby drank zinc, and the zinc content was moderate, which was quite good.
