問題詳情

Reading ComprehensionHow do you react to the taste of different foods, like coffee or lemon? Do they have a flavor that you like? Or do they taste very strongto you? Why do people react differently to different flavors?We all know that different people have different food preferences. Researchers have discovered some reasons for these differences.Your culture and your life experience are partly responsible for your preference for certain foods. Your food preferences are also partlygenetic. (Your genetic preferences are the ones that you were born with.) In order to discover people’s genetic preferences, researchers usea chemical called PROP. People taste it and respond to the taste. To some people, PROP has no flavor. The researchers classify these peopleas “nontasters.” To other people, the flavor of PROP is a little bitter, or sharp. These people are “tasters.” Then there are people who can’tstand the flavor of PROP. They find it to be unbearably bitter. These people are the “supertasters.” Tasters have more taste buds on theirtongues than nontasters do, and supertasters have more taste buds than tasters do. This explains why supertasters are more sensitive toPROP and to the flavors in certain foods. So if you think the flavors in coffee, grapefruit juice, and broccoli are very strong, you may be a“supertaster.”
