Scientists have been studying the reason

题目：

Scientists have been studying the reasons why some people don't like the taste of certain vegetables. They found that people inherit(遗传)some genes from their parents that cause them to like or dislike certain vegetables.

In their research about tastes, scientists found that there are three types of people in the world. First, there are non-tasters, who are not very sensitive to sweet-tasting foods or bitter-tasting foods. The people of the second type are just called tasters, and those of the third are super tasters who are very sensitive to sweet and bitter flavors. Children of the third type, who are super-tasters, will probably not like vegetables such as broccoli and Brussels sprout because of their bitter taste. This is unfortunate, because super-tasters might avoid eating foods that are important for their health.

The scientists said that thousands of years ago. On the other hand, super tasters actually had an advantage over other types of people. At that time, super-tasters could avoid eating bitter-tasting poisonous plants which other types of people would eat.

From this research about tastes, we learn some interesting things about super-tasters. For one thing, super-tasters have more taste buds(味蕾)on their tongues. And, to super-tasters bitters foods taste very bitter, and sweet foods taste very sweet. Super-tasters might also not like spicy food made with chili pepper, because it would be too hot for them. Furthermore, female supper-tasters probably won't be very fat, but they do seem to enjoy cooking more than other types of people.
