As the subject line says, I've been thinking getting one, as I'm interested in how what we eat affects us, how food can heal. But I'm wondering how much is "science" involved. I've never been very good in the sciences, I was a bit overwhelmed with the multitude of information, without (to me, anyway) relevant application. But nutrition seems very relevant to me. So, would this aversion to sciences, specifically chemistry, be a big problem for me? How much of the coursework, and possible career opportunities, deal with science, per se?
