1 . Chinese people are eating too much salt. People in China eat about 10.5 grams of salt each day, much higher than the 6 grams advised by Chinese Dietary Guidelines (2016). To solve this, China issued(发布) the first salt reduction guide for its food industry on April 18, 2018. The government hopes that can help people have salt in a proper way.
If the guide is followed properly, the salt intake (摄入量) for Chinese people will drop by 20 percent by 2030. The salt we take in mainly comes from processed food. For example, there is about 0.66 grams of salt in a 104-gram can of Lay’s potato chips. That is about 10 percent of the daily salt intake. A 100-gram bag of Kang Shi Fu instant noodles has nearly 2 grams of salt. Therefore, it’s necessary for the companies to reduce salt in their products.
A small amount of salt makes food taste better and is important for good health, but eating too much increases the risk of high blood pressure, heart attacks and strokes (中风), the Xinhua News Agency reported.
Less salt leads to better health. And there’s no need to worry that food will be less tasty in the future. A study found that it’s easy for people to reduce their salt intake. Although you may think your food is not salty enough at first, you will get used to the new taste soon.

It’s hard to say no to hamburgers, French fries and all of the other junk food. However, eating too much junk food can harm your body, especially if you’re between the ages of 10 and 19. “Junk food shapes teenage brains in ways that harm their ability to think, learn and remember. It can also make it harder to control impulsive (冲动的 ) behaviors,” said Amy Reichelt, at Western University, Canada. “It may even raise a teen’s risk of mental (精神上的) problems.”
Reichelt and two other researchers reviewed more than 100 studies, about how poor food choices can affect teenage brains. They found teenagers are more sensitive (敏感的) than any other age group to foods with a lot of fat and sugar as their brains are not yet fully formed.
Teenage brains are still developing the ability to notice risks and control actions. The prefrontal cortex (前额皮质) is the part of the brain that tells us we shouldn’t eat chips all the time and helps us control ourselves. However, this part doesn’t fully develop until we are in our early 20s.
Meanwhile, teen brains get more excited from rewards (奖励). The parts of the brain that make us feel good when we do something enjoyable — like eating tasty foods — are fully developed by the teen years.
In fact, these parts are even more sensitive when we are young. That’s because dopamine (多巴胺 ), a natural chemical that makes us feel happy when we experience something good, is especially active in teenage brains.
Therefore, the teen brain has two attacks against it when it comes to saying no to junk food. “It has an increased drive for rewards and reduced self-control,” said Reichelt.
Reichelt and her team did their own study using mice, whose brains develop much like our own. They discovered that “teenage” mice that had high-fat foods performed worse on memory tests than those eating normal foods. Researchers said the high-fat foods may make the mice’s prefrontal cortex work less effectively.
So, what’s the best way to say no to junk food? The answer is exercise. When we exercise, the brain becomes less sensitive to food, besides this, it also helps our brains grow and become better able to make wise decisions and control our behaviors.

10 . If you like chocolates, you are not alone. Millions of people around the world say that they can’t live without chocolate. But have you wondered if chocolate is harmful to your health? Let’s separate the truth from the facts about this popular food.
Chocolate makes you happy.
There are over three hundred chemicals (化学物质) in chocolate, which make our brain active and enable us to feel happy. For example theobromine (可可碱) can help increase feelings of happiness and makes you feel less stressed. The caffeine (咖啡因) in chocolate can give you more energy and is also found in coffee and tea.
Chocolate makes you fat.
Chocolate is commonly seen as a kind of fattening food. In fact, cocoa beans are full of antioxidants (抗氧化剂) that are good for health. However, a lot of antioxidants are removed during the process to clear up their bitterness (苦涩). Most chocolates have high sugar and fat and only a little cocoa. Eating these and other chocolate desserts like cakes and cookies can really increase your weight.
Chocolate causes bad teeth.
It’s not chocolate itself that causes tooth decay (腐烂), but the sugar in chocolate and bad teeth-brushing habits. In fact, it’s believed that cocoa butter covers our teeth, and this might actually protect instead of hurting them,
As with most things, chocolate only become a danger when you eat it too much. It’s important to remember that most of the advantages of chocolate come from cocoa. That’s why dark chocolate is the healthiest choice. So choose your chocolate wisely, eat it properly, and you will get the best of both worlds—happiness and health.
