Okay kiddo, sometimes people want to eat food that is good for their bodies and helps them stay healthy. This is called "diet food". Diet food includes things like fruits and vegetables, lean proteins like chicken or fish, whole grains like brown rice, and low-fat dairy products like milk and cheese.
When people eat diet food, they are often trying to lose weight or live a healthy lifestyle. This means they might avoid foods that are high in sugar, fat, and calories. Examples of foods they might avoid are candy, soda, and junk food like chips and cookies.
It's important to remember that everyone's definition of diet food is different. What might be considered healthy for one person might not be for another. It's always a good idea to talk to a doctor or nutritionist to find out what kind of diet would be best for your body.
So remember, kiddo, diet food is food that is good for you and helps you stay healthy!
