Question: How does food effect your body after you eat

Lots of different ways! I can think of a few:

Your body needs to generate energy in order to do things, for instance. That’s why you feel weak if you don’t eat. So we use some of our food to keep our muscles working and generate energy!

We also need to make new cells. Our body makes new skin and hair to replace the old stuff, and if we break a bone or hurt ourselves our body needs to repair that too. Some of this stuff is very special, so we need special minerals or chemicals (you might have been told that your body needs calcium to make healthy bones and teeth, for instance!).

Some food and drink have very special effects! Coffee and Coca-Cola have something called Caffeine in it. Caffeine is what’s called a stimulant – it makes you feel more alert, and can help stop you from feeling sleepy.
