📖 Read the story
Many people love sweet drinks like cola or hot tea. These drinks have something called caffeine. Caffeine is a substance that makes us feel awake. Many adults drink it every day. But is it good for children? A clever teenager did a science study. She looked at how caffeine affects young animals. She found that caffeine can change our genes. Genes are like a secret instruction book inside our bodies. They tell our bodies how to grow. The study shows that caffeine can stop some important brain instructions from working. Young brains are still growing and are very different from adult brains. Too much caffeine can hurt a growing brain. For young people, it is much better to choose water or milk instead of cola. This helps your brain grow strong and healthy.
