I’ve got to do a talk at university on a nutrition topic and was wondering if anyone had some sensible ideas!!

Healthy nutrition in teenage years.It’s for a school project.

What is the amount of nutrition that a growing teenager need and what is some good food to eat

I want to be a dietician or a nutritionist.
If you can tell me, I would appreciate it.
I have looked into nutrition at some university’s websites but they didn’t have that listed under any departments. I dunno…. maybe I wasn’t looking good enough.
btw, is the University of York good?

I need the definition to nutrition and the six components….
