According to scientists, young people’s taste buds are not ready for the bitter taste of some vegetables. Our taste buds develop as we get older, but young people prefer sweet food. In fact, most of us do, just like our prehistoric ancestors. They ate a lot of sweet fruit because it was widely available and easy to notice on trees and bushes, and it was a good source of energy. They also realised that they had to be exceptionally careful with plants that had a bitter taste, since they were often poisonous! Apart from bitter and sweet, what other tastes can we detect? You might be surprised to learn that our taste buds can only distinguish two more: salty and sour. When we reach early teens, we start to prefer sour things to sweet things. However, recent studies have shown that girls and boys experience taste in different ways. Girls have more sensitive taste buds and can differentiate flavours more easily, especially sweet and sour, while boys prefer stronger, more extreme flavours.
When we smell food, our mouths produce saliva(唾液)and when we eat it, the saliva transports its taste to our taste buds. Without saliva, some food would have no taste at all. We don’t just taste with our mouths, we also use our noses! When food is cooked, it produces aromas(芳香)that make us hungry. When we put food in our mouths, our taste buds and noses work together to decide what flavour the food has. Have you ever noticed that food which has been cooked doesn’t taste as good when it goes cold? When the cooking smells disappear, so does some of the taste.
The texture of food on our tongue is also important in our perception of its taste. This is because our brain perceives the look or feel of something and sends a message to our tongue telling it whether or not to like that food.
If you really don’t like some vegetables on your plate, you can claim that there is a universally accepted scientific explanation for this.
