What is taste?

A Question A Day

If you can tell the flavor of food, it’s thanks to one of your 5 senses: taste. Things don’t have the same taste: cherries are sweet, lemons are sour, artichokes bitter and olives salty. These are basic flavors... that you discovered through the amniotic fluid in your mummy’s tummy, long before you were born.

How does taste work?

When you eat, the molecules of the food mix with your saliva and let out the taste. Then, this taste is picked up by the cells of thousands of taste buds on your tongue. But that’s not all! Food molecules also give off smells which go from your throat to other sensors, in your nose. Try it! If you hold your nose, it’s quite hard to taste anything! Taste and smell information is then sent to your brain, which analyses and memorises it. Everything you like or don’t like is recorded. Luckily, your taste can change as you get older! For example, babies don’t like anything bitter. It’s a genetically programmed survival reflex: in nature, poisons are often bitter. Yet, many grown-ups like dark chocolate or coffee, which are quite bitter! Why? The more you taste certain things, you get used to them, and sometimes you end up liking them. Fancy some more brussels sprouts…?
