What are food that are good for you and your skin?

Hello:) my name is nina. I am 16. This year along with last I’ve felt like my body is kinda running slower than usual. This could be because I’ve stopped playing soccer, baseball, and acrobatics+gymnastics. Gained 6 pounds since halloween. And my skin is getting bad. I was wondering what are some dietary foods that I can eat instead of others. That are good for the skin, body and soul?:slight_smile:
