When you look at your food, some ingredients are easy to see. For example, there is cheese on your pizza and butter on your bread. But our meals are also filled with ingredients you can’t see. And you might be surprised to learn just how much those hidden (隐藏的) ingredients affect your health.
Salt is a perfect example of an ingredient that you might not notice, even when you eat a lot of it. More than 75% of the salt we eat is hidden in restaurant meals, fast food and processed (加工过的) food , such as French fries, hot dogs and even biscuits.
Salt is important to us. It keeps our muscles (肌肉)working and our nerves (神经)sending  messages through the whole body. Salt can be used to clean teeth, to make our skin smooth or added to a relaxing bath. Salt is also used to help make food last (持续) longer.
However eating too much salt can cause heart problems. For a long time, heart trouble has been regarded as an adult problem, but new research shows that salt is starting to affect kids. Then how much salt is safe for kids every day? Let's look at the following chart:
     Ages
   Amount of Salt Every Day
1—3 years old
2 grams
4—6 years old
3 grams
7—10 years old
5 grams
11 or more than 11 years old
6 grams
Kids should not eat more than that.

Do you know Eskimos? Let me tell you something about their lives.

Eskimos live near the North Pole(北极).There are only two seasons there, winter and summer.

There is no spring or autumn there. The winter nights are long. You can’t see the sun for more than two months, even at midday. The summer days are long. For more than two months, the sun never goes down and there’s no night.

Eskimos have warm clothes. They make their clothes from the skins of animals. From skins(皮毛) they make coats, caps and shoes.

Near the North Pole trees can’t grow, for it is too cold there. The Eskimos have to make their houses from skins, snow or stone. When they got out in storms and can’t get back home, they make houses of snow. They leave these houses when the storm is over.
