Salt is very important to us. We need salt in our food. But do you know how much salt we need every day?

How much salt do we eat?

Most people eat too much salt without even realizing(认识到) it. You could be eating too much because 75% of the salt we eat is just in the fast food we buy. So we should add(添加) little salt to food when cooking at home.

Why is salt bad for our health?

Salt has something to do with our blood pressure (血压). Salt can make blood pressure high and becomes one of its main reasons.

How much salt should we eat?

The World Health Organization(世界卫生组织) says that adults should eat no more than 5 grams (克) of salt a day, and children even less.

After exercising, the first thing that many of us want to do is drinking a glass of cold water. To feel the water travel down our throat is so good. However, many people have often told me not to do so. Is drinking cold water really unhealthy? What does science have to say about it? Let’s find out.

Cold water is said to slow down a person’s digestion (消化). This has been shown in many studies. Most researchers believe that having cold water or a cold drink reduces our body’s core (核心) temperature. Therefore, the body needs to burn energy to bring our core temperature back up to normal. This energy could have been spent digesting the food we had just eaten.

Think of your digestive system as a hot wok (锅) that fries food. If someone suddenly threw cold water into this burning wok, what would happen? Doing this would be dangerous. Similarly, when you drink cold water while eating, it’s like adding water to a hot wok.

Of course, it isn’t that bad. But it is a good way to explain why drinking cold water may be a bad idea. That’s why many experts suggest that you should avoid drinking water during meals. If you cannot do that, drinking water at room temperature is a better choice.

Drinking cold water can worsen headaches too. A study carried out in Sweden found that a lot of women experienced headaches after drinking cold water. What’s worse, you will get a sore throat and a runny nose (流鼻涕) if you drink too much cold water.

For thousands of years, traditional Chinese medicine has advised the avoidance of cold drinks. Modern studies have also pointed out that drinking cold water is harmful to your health. So, you are better off avoiding those ice cubes in your water.

It is very easy to cook instant noodles in a short time by putting the noodles into the boiling water. However, have you ever thought whether it is the right way of cooking instant noodles?

When we first take out the noodles, we can notice that the noodles are joined together nicely as a piece. However, few people know that when making the instant noodles, wax coating will be put on the noodles. The wax coating on the instant noodles is used to prevent the noodles from sticking together. It makes the noodles look very nice.

Researches have shown that the wax coating on the noodles is quite harmful to our health. If you eat the instant noodles today, you’d better wait for several days before you eat instant noodles next time, since our bodies need about at least four days to clear the wax coating away from our bodies. Do you know ▲ ? It will lead to cancer if the wax coating is stored in our bodies for a long time.

So it is very important to wash away the wax coating on the instant noodles if we don’t want our bodies to be in danger. You can do like this: 1. Wash the instant noodles with warm water first and then pour away the water containing the wax coating. 2. Repeat Step 1 and try to stir the noodles to wash away the wax coating on the noodles before cooking it in a new pot of water.

I hope this passage will make those who enjoy eating instant noodles and eat the instant noodles often know about the hidden danger of instant noodles. Although the instant noodles are very easy to cook and help us save a lot of time, I still don’t think it’s healthy to eat them too often or too much.
