I'm 14 and a health freak?

I'm vegetarian, I don't drink soda or anything sugary. tea, juice and water is all I drink. I don't eat any junk food. Fruits, veggies, and starches are almost all I eat. But I eat peanuts to get protein. Everyone in my family says in weird I'm the black sheep in the family. Is there honestly anything wrong for eating right for my age?
