Looking for a natural nutrition course in the U.K

Hi, I really want a career in natural therapies, most probably natural nutrition, though there are loads of others I'd love to learn but can't really do them all! I'm just so, sooo confused where to start. I've seen tons of websites on the internet advertising natural nutrition courses and they all LOOK good but I'm wondering if anyone here has done one they highly recommend?? Any help would really mean alot to me, I thought about the A Level/degree route but I really don't think that's for me. Thank you!
