<p>I want to major in biology for undergraduate, just want to know that is it really doesn't lead to any decent job except for researching?
What career can I have without a M.D or Ph.D?
And what about food science/nutrition?</p>
<p>The thing about biology and other life-science majors, they are relatively few opportunities at the undergraduate level. You can try to get into a masters program for Nutritional sciences.</p>
