A
A poor farmer had a friend who was famous for the wonderful apple trees he grew.
One day, the friend gave the farmer a young apple tree and told him to plant it. The farmer was pleased with the gift, but he did not know where to plant it.
He was afraid that if he planted the tree near the road, strangers would steal the fruit. If he planted the tree in one of his fields, his neighbours would come at night and steal some of the apples. If he planted the tree near his house, his children would take the fruit. Finally, he planted the tree in his woods. But without much sunlight or good soil, the tree soon died.
Later the friend asked the farmer why he had planted the tree in such a poor place. "What's the difference?" the farmer said angrily and then told what he had thought.
"Yes," said the friend, "but at least someone could have enjoyed the fruit. Now you not only have robbed everyone of the fruit, but also have killed a good apple tree!"

What about sweet food?
Everyone likes the taste of sweet food! A small amount of sweet food can be part of a healthy meal plan. Sugary food includes soda pop (苏打汽水), fruit drinks, honey, and candy. Desserts such as cakes, pies, cookies and ice cream contain a lot of fat as well as sugar. If you choose to eat any of the sweet food, just have a small amount at the end of a healthy meal. Have a piece of fruit if you are still hungry. Drink water, sugar-free soda and sugar-free fruit drinks if you are thirsty, instead of drinks that are all high in sugar.
How much should you eat?
Your height, weight, age, whether you are a boy or a girl, and how active you are will affect how much food you need to eat each day to stay at a healthy weight. Everyone is different. Talk to your doctor or diet expert about how much to eat, especially if you need to lose weight. If you take in more food than your body burns, you will gain weight. If you take in less food than your body burns, you will lose weight. Being active and eating smaller amounts of food and less sweet or fatty food can help overweight kids lose weight in a healthy way, and keep their hearts healthy.
