Question: how does sugar effect the brain?

Hi Sophie. The brain needs more energy to function than any other part of your body. It’s hard work doing all that thinking! We get a lot of our energy from sugar, so we need sugar for a healthy brain. However, just like anything, you can have too much of a good thing. If you eat too much sugar, it can make your brain slower and unable to form memories. It can also lead to long-term psychological problems like depression. Have you ever heard of a ‘sugar crash’ where you feel all drained of energy a little while after a sugar-binge? Imagine that feeling all the time 🙁

So the moral is: sugar is fine, but not too much!
