<p>Very much in agreement with 2manyschools- “I want to understand nutrition” is about as broad and as multidisciplinary as “I want to understand war” (which I told myself I wanted to do some very long time ago.) </p>
<p>It sounds like you don’t want an undergraduate certification to be a nutritionIST (if such a thing exists) nor does it sound like you want to be a bioengineering undergraduate major (as I read your OP, a bioengineer studying GMO’s would fall under your broad label, and there are colleges with bioengineering majors.)</p>
<p>So yes, apply widely and broadly to schools that interest you. BUT I just have to add- and I would not have thought of it without the reference to NYU- which actually has the exactly the kind of focused interdisciplinary program you referred to in your OP.</p>

<p>Don’t ask me how I knew that :-)</p>
