Scurvy

Scurvy is when you don't eat enough fruits and vegetables that have a special thing called vitamin C. Vitamin C helps your body to stay healthy and strong. But if you don't have enough of it, your body gets sick, sores on your skin, and your teeth can fall out.

So, when sailors used to go on long trips without any fresh food or fruits, they would get scurvy. That's why sailors used to carry limes and lemons with them on ships to stay healthy.

Even today, it's important to eat fruits and vegetables that have vitamin C to stay healthy and strong!
