Am I doing the right thing by majoring in Biology?

I want to be a Registered Dietitian, and I know I need to go through a CADE certified program to get my license, but the college I'm attending my freshman year doesn't have that program. The college offers biology, chemistry, and health for majors (that I think are more related to nutritonal science than not), and of those I thought Bio is the closest related major. I know that as a freshman it doesn't really matter, but I want to transfer to a college that has the CADE certified stuff for my sophomore year. And the college I have in mind is highly competitive. Did I choose the right major? =/
