We all think eating fruits means just buying fruits, cutting them and putting them into our plates. It's not as easy as you think. It's important to know1and when to eat.

But when you eat two pieces of bread and then some fruit, it is stopped from doing so. Do you know the reason? You have probably heard people saying—every time I eat watermelon, I burp (打嗝). When I eat a banana, I feel like3 to the toilet. When the fruit is 4with other food, it produces gas. That's why you will feel 5. Actually, we will not check if you eat the fruit on an empty stomach.

Eating a whole fruit is better than drinking the juice. When you6want to drink fruit juice, drink only7fruit juice, not from the bottles or cans. Don't drink juice that has been heated up. Don't eat cooked fruits because you don't get the nutrients (营养成分) at all. You only get the8of the fruit.

Height is just one of the features your genes(基因) decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too. But if you have questions about how tall you're going to be, ask your doctor if he or she can help you find them out.

But genes don't decide everything. For example, eating an unhealthy diet can keep you from growing to your full potential(潜力). Getting plenty of sleep and enough exercise will help you grow to the expected height.

It's natural that you're wondering how fast you should grow. There's no perfect or right answer. Generally speaking, kids grow about 6 cm a year between age 3 and the time when they start puberty.

Your doctor will know how your growth has been going over the years. 2 cm here and 3 cm there make a little difference to the height you're at now. How have you been growing up to this height? What other changes may your body be going through?

Don't be amazed if you seem to have grown a lot in a very short time. Everyone has a growth spurt(高峰) during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later — between 7 and 13 for girls and 9 and 15 for boys.

You'll usually begin to notice that you're growing faster about a year after your body starts to show the first changes of puberty.
