Portion size means the amount of food you eat at one time. It's like when you get a piece of pizza and you eat just one slice, that's your portion for that meal.
When we eat, it's important to have the right amount of food so that we can feel full and satisfied without eating too much. Eating too much food can make us feel sick, and it's not good for our bodies.
Different foods have different portion sizes. For example, you might need to eat more broccoli to feel full than you would need to eat a slice of pizza.
When we are choosing what to eat, we should think about the portion sizes and choose foods that will fill us up without eating too much. It's also important to pay attention to how much we eat - we can use small plates, bowls, or cups to help us control our portion sizes.
Overall, portion size is about eating the right amount of food for our bodies so that we can feel good and healthy.
