Should you major in Health Science if you don't plan on going to professional school?

I know a BS in Health Science is pretty useless unless you go to grad school. I heard that grad school is pretty a backup plan for Health Science majors since all Health Science majors want to go to a professional school first(pharm,med, optometry, ect.) .However, I feel like I am wasting my time with this rigorous major when I don’t want to go to a professional school at all. I actually just want to be a nutritionist.

I wouldn’t say a health sciences BS is “useless” unless you go to graduate school.

“Nutritionist” is not a term that is protected in most U.S. states, so a B.S. in health sciences can actually lead to work as a nutritionist if you want. You could major in health sciences, find internships that are related to nutrition and food, shadow or volunteer with a nutritionist or dietitian, and then seek out jobs that only require a bachelor’s that are nutrition-related. Having a BS in health sciences may be an advantage in this area because you have domain expertise. For example, a quick search of my local area (greater Seattle area) turned up some listings for nutritionists that asked for a BS in “nutrition or another health sciences area.”

Now if you want to be a registered dietitian - someone who counsels clients on proper diet and nutrition (sometimes at the nexus of other conditions), or who consults with companies in a professional role, that’s a regulated and licensed profession that you need specific training for. This is going to vary by state but with an undergrad degree in health sciences you would probably need to pursue a master’s in dietetics or some other approved program that makes you eligible to take the necessary exam.
