Welcome to Science News! Today we are learning about a special thing called arginine. Arginine helps our bodies make protein. Protein is very important because it makes us grow and stay strong. Recently, scientists did a new test with mice. They gave some mice more arginine in their meals. These mice were very healthy. They were better at fighting the flu. Arginine also helped the mice fight serious sicknesses like cancer. Arginine is good for our immune system. Your immune system is like a small army inside your body. It fights bad things and keeps you safe. The scientists are excited about this. However, they need to do more tests. They want to see if arginine helps people in the same way. You should always talk to a doctor before you try new things. This discovery might help us stay healthy in the future!
