为什么我们的身体里大部分是水?

Why is most of our body made of water?

水占了小朋友身体的六成以上,它溶解营养、调节体温,还让关节滑溜溜地活动。没有水,身体里的化学反应就没法顺利进行。
Water makes up over sixty percent of a child's body; it dissolves nutrients, controls temperature, and keeps joints moving smoothly. Without it, the body's chemical reactions could not run well.

为什么吃饱了就不想吃了?

Why do we stop wanting food when full?

胃被食物装满时会告诉大脑"够啦",大脑就让你放下勺子。听身体的信号,吃到不饿就好,不用硬塞。
When the stomach is filled, it tells the brain "enough," and the brain makes you put down the spoon. Listening to this signal, you eat until not hungry rather than overfilling.

为什么吃太咸对身体不好?

为什么小朋友喜欢甜甜咸咸的味道?

Why do kids like sweet and salty tastes?

远古时甜食代表安全的能量、咸味代表身体需要的矿物质,所以人类天生偏爱它们。现在食物很丰富,喜欢这些味道没问题,但要注意分量,别让糖盐抢走了其他营养。
Long ago sweet meant safe energy and salty meant needed minerals, so humans naturally prefer them. Today food is plentiful, and liking these tastes is fine, but watch portions so sugar and salt do not crowd out other nutrients.
