There are many kinds of food in the world. Scientists learn a lot about them. They say that there are some kinds of food people must eat every day. For example, people must eat some green and yellow vegetables. We shouldn't eat too much meat. People also need to eat some fruits, bread and rice. Of course our bodies need some water and milk.

Scientists say people in different countries and different places eat different kinds of food. They cook food in different ways. Different people eat at different times. In one place, people eat once or twice a day. But in another place, people eat three or four times. The scientists say when to eat and how many times to eat are not important. What we eat is the most important thing.

Nowadays(现在), the world faces two problems. People in some places, for example, in Africa, are not full. Many people are eating junk food. It's bad for people's health. So it's our duty to make everyone full and make everyone healthy.

We are told breakfast is the most important meal of the day, and dinner the most enjoyable. But what about lunch? In today’s fast-paced society, not many people take time to enjoy this midday meal. We just take a quick salad, or buy a sandwich and eat at our computers. Sometimes, if there is a deadline around the corner, we just give up lunch. The development of technology hasn’t done our eating habits much good, either. We are constantly distracted（分神） by e-mails, social media, 24-hour news, and hand-held electronic devices.

Long working hours can cause all kinds of health problems. Employers should encourage workers to take time off for lunch. This is because long lunch breaks can benefit both people and society. To take a lunch break is to slow down and gain some views. A break from work allows us to think cleverly and outside the box. It also puts our daily tasks into a wider context（环境）.

What we eat at lunch is also important. A fast-food lunch is more harmful than not having lunch at all. And it’s not just about calories and unhealthy food. Recent studies show that fast food also has negative effects on how we think. However, if we sit down at a proper restaurant and chat leisurely with colleagues, we are more likely to slow down and talk about something that hardly can be achieved in a noisy and crowded fast food chain.

School should make our lunchtime longer. Now, our lunchtime is short. Many of my classmates have some homework to do after lunch .

Food in our dining hall is not nice at all. There is always pork, fish, and cabbages. The soup is always cold. I think we should have different kinds of food every day. And why can’t we have hot soup every day ? I am fed up with what we eat !

For 99% of human history, people took their food from the world around them. They ate all that they could find, and then moved on. Then around 10,000 years ago, about 1% of human history, people learned to farm the land.
The kind of food we eat depends on which part of the world we live in, or which part of our country we live in. For example, in the south of China they eat rice, but in the north they eat noodles. In European countries near the sea, people eat a lot of fish. In central Europe, away from the sea, people don’t eat so much fish, but they eat more meat. For example, in Germany and Poland, there are hundreds of different kinds of sausages.
In North America, Australia, and Europe, people eat with knives and forks. In China, people eat with chopsticks. In parts of India and the Middle East, people use their fingers to pick up food.
Nowadays it is possible to transport food easily from one part of the world to another. We can eat whatever we like, at any time of the year. In Britain, bananas come from Africa; rice comes from India or the U.S.A.; strawberries come from Chile or Spain. Food is a very big business. But people in poor countries are still hungry while people in rich countries eat too much.
