I love biology & am eager to help people b/me healthy & fit, so would a job as a nutritionist be good for me?

I love love love science (mostly biology and chemistry) and for the past three years I've wanted to be an optometrist....but this year i took physics and i don't like it very much, and it is a big part of optometry....however, i went to a nutritionist today (i am recovering from an eating disorder) and I had an epiphany that maybe helping people become healthy is what i really want to do with my life....i talked to an intern at the nutritionist's office, and she said she is LOVING her college experience (she is going to be a nutritionist)....would this be a good field for me? is it okay salary wise? thanks!
