I would like to become a nutritionist but I have a felony conviction.is it possible
To acquire this degree?

You may be able to get into a university, but it won't be easy to find a job. Nutritionists work in hospitals, schools, nursing homes, colleges, and large corporations. I'm not sure many of these places would hire you.

You may acquire the degree, but will find it harder to get a job. Where or what job in the field where you looking at.

You can get the degree ,but 50% of jobs in that field are for hospitals.

Your best bet would be to be your own boss.
