Experts in nutrition (营养) suggest that we should eat at least five different kinds of vegetables and fruit a day. There are a lot of vegetables and fruit to choose from and they taste delicious.     1    

Why do we go to the trouble of growing on our own? Here are several good reasons.

Food that you grow yourself is always fresh.     2     When you have tried it, you will agree that vegetables and fruit that are eaten straight from the garden taste better than anything you can buy in a supermarket.

    3     Food producers often use fertilizers (化肥) and pesticides (农药) which can end up in your food. If you grow your own, things are different.     4     You might also choose to grow some traditional vegetables and fruit. These often have more vitamins, minerals (矿物质) and protein (蛋白质) that keep you healthy.

If you have a large garden, growing your own is easy. And you can grow your own even if you only have a small backyard or a balcony (阳台). Some food can grow well in pots including lettuce, tomatoes, potatoes and carrots.     5     Just make sure there are holes for drainage (排水) and a small plate under them to catch drops of water.

Happy gardening!

A．You can pick and eat it at once.

B．But where to grow your own is a problem.

C．Homegrown food is likely to be healthier.

D．You can control what goes on and into the food you eat.

E．But it’s best for you to grow your own vegetables and fruit!

F．You can recycle plastic bottles and cups to grow something.

2 . Healthy eating doesn’t just mean what you eat, but how you eat. Here is some advice (建议) on healthy eating.

    1     It can help you to see others’ healthy eating habits. If you usually eat with your parents, you will find that the food you eat is more delicious.

Listen to your body. Ask yourself if you are really hungry. Have a glass of water to see if you are thirsty—sometimes you are just thirsty, you need no food. Stop eating before you feel full.

Eat breakfast. Breakfast is the most important meal of the day. After you don’t eat for the past ten hours, your body needs food to get you going. You will be smarter after eating breakfast.

Eat healthy snacks like fruits, yogurt or cheese. We all need snacks sometimes.     2     This doesn’t mean that you can eat a bag of chips instead of (代替) a meal.

    3     With our busy life, we always put off eating dinner until the last minute.     4     Thus will give your body a chance to digest (消化) most of the food before you rest for the next 8-10 hours.

A．Eat with your parents.

B．Eat with others.

C．Don’t eat too much.

D．Don’t eat dinner late.

E．Try to eat dinner at least 3 hours before you go to bed.

F．In fact, it’s a good idea to eat two healthy snacks between your three meals.

5 . Water plays an important role in keeping you healthy. This should come as no surprise. Much of your body is made up of water, after all. It keeps your body working properly. But did you know that too much water can poison (使……中毒) you?

Water poisoning happens when people drink too much water. This makes sodium (钠) in their blood too little.

You probably already know that too much sodium can be unhealthy. That’s true, but too little is also harmful. When you have too little sodium in your body, a lot of things will go seriously wrong in your body. Then you will feel really terrible.

Your brain may begin to go wrong. You may get a headache, feel very tired and want to throw up. In these cases, water poisoning can be deadly. You will need to be sent to a hospital right away.

Protecting yourself from water poisoning may seem easy—just don’t drink too much water, right? In some situations, however, this is easier said than done. For example, when you do some heavy exercise, such as running a marathon, you may have to drink a lot of water. It is then important to balance the number of water you drink with the number of water your body is losing. This can help you stay healthy whenever you are exercising.

So, how much water should a person drink each day? For years, we have been told to drink two liters (升) of water a day. But in fact, the actual number needed is different for each person. Today, most doctors are telling people that they should drink water whenever they feel thirsty. We can’t live without water. Neither can we live with too much water in our bodies. Make sure you take the right number of it each day—staying healthy is all about staying balanced!

10 . Once you begin to eat potato chips, you may keep eating until the bag is empty. Have you ever experienced this? Why can’t you stop eating these salty chips? Scientists said it is due to a kind of neuron (神经元).

Scientists at the Beth Israel Deaconess Medical Center in Boston have found that some neurons can make us want to eat salt.

The neurons take note of whether our bodies are lacking sodium (钠), a main part of salt. Then, they send signals (信号) to our brain to encourage us to eat more salt, according to the Daily Mail.

How do these neurons work?

Scientists did experiments on mice. They found that when mice lack sodium, their body gives off a kind of hormone (荷尔蒙) called aldosterone (醛固酮). This hormone then makes these neurons become active.

More research showed that adding salt to meals makes people enjoy their food more, Time magazine reported. This may cause people to continue eating even if they are full.

Scientists from Deakin University in Australia asked healthy people to eat the same food for lunch for four weeks. The amount of salt in the food was changed each week. At the same time, the scientists measured how much these people ate. They also asked the people how they felt about the meals; for example, if they felt happy or were still hungry after eating.

The results showed that salt made people eat 11 percent more food and calories. When eating low-salt meals, they could control (控制) over how much they ate. “But when we add salt to that food, all of a sudden those controls are gone,” researcher Russell Keast said to Time.
