What's a Protein?

Have you ever wondered how professional wrestlers, circus acrobats, and Olympic athletes get strong muscles? Well, it has a lot to do with the nutrient protein, which builds their muscles. Protein is a nutrient that's naturally found in plants and animals. It's made of microscopic building blocks called amino acids. When you look at amino acids under a microscope, they look like tangled strings. Protein is an important and necessary part of your daily meals to help you to grow and stay healthy.

Parts of the Body Made of Protein

Protein is a superfood! This nutrient has a lot of work to do to keep your body running. When you eat protein, it breaks down into amino acids during digestion. Then your body sends these amino acids to different parts to keep them healthy and growing. One part of the body that needs protein are your muscles. Children grow very quickly, and protein helps your muscles keep growing to help you move, walk, run, and exercise.

Did you know that blood is also made of protein? Blood carries nutrients and oxygen throughout your body. Protein also builds organs such as your heart. Your bones even need protein to grow, and stay strong and healthy.

As you can see, protein is important to your health. So the next time you're having fun on the playground with your friends, you'll be happy that you have eaten healthy servings of protein to have the strength and energy to enjoy yourself!
