It happens from time to time: you feel terrible when you take your first bite of a certain food, but after eating more, you find yourself enjoying it. This is what is called an acquired taste. But why do our tastes change?

The answer, according to a recent study presented at an American Chemical Society meeting in Boston, lies in proteins in our saliva (唾液).

Most of us tend to think saliva, almost entirely made up of water, is “only a mouth lubricant (润滑剂) helping us to swallow food,” the New York Times said. However, it also contains many proteins, which can help break food down, protect our teeth and help in tasting food.

To explain how these proteins affect taste, a team of scientists from Purdue University in the US invited 64 volunteers to drink a bitter-tasting chocolate milk three times a day for six weeks and rated their tastes at the same time.

According to the research, the participants found a strong bitterness on the first day, but the unpleasant flavor came to decrease as time went on and finally disappeared.

That is not all that was changing. A noticeable increase in the levels of proline-rich (富含脯氨酸的) proteins was found in the saliva samples of the test subjects in the research period. These proteins serve to reduce the bitterness we taste and improve our adaptation to this flavor.

“We think the body adapts to reduce the negative feeling of these bitter compounds,” said Cordelia Running, a food scientist at Purdue University. “Saliva changes flavor, which in turn changes eating choices.”

This change in taste not only makes the food tastier, but also helps people keep an appetite for healthy food whose flavor might otherwise keep them away.

One day, these proteins may even be extracted (提炼) and used as a separate food additive that could help people stick to healthy food whose flavor they continue to dislike, researchers told Science Alert. And according to Running, even it doesn’t happen, the idea that “maybe some little piece of your body is actually trying to help you” could really benefit some people. Let’s wait and see.

1.What does the underlined phrase “an acquired taste” in Paragraph 1 refer to?

A. The appetite for healthy food.

B. A mouth lubricant helping to swallow the food.

C. Something that tastes very delicious at first bite.

D. A preference that is only formed after great repetitions.

2.What contributes to the changes of our taste?

A. Our negative feelings of food.　　 B. Our adaptation to this flavor.

C. The proteins in our saliva.　　 D. The flavor of the food.

3.Which of the following statements is TRUE according to the text?

A. Saliva consists of many proteins besides water.

B. The unpleasant flavor will increase with time going on.

C. A separate food additive has been extracted from the proteins.

D. Proteins have nothing to do with the changes of our taste.

4.What can we infer from the last paragraph?

A. There will be bitter candy in the future.

B. You can change the flavor as you like in the future.

C. The researches will go on studying these proteins.

D. It won’t be long before we can make unhealthy food healthy.
