Welcome - I am new here myself!
I am sure nutrition is a great area to be working in. It comes into my work as a homeopath and health adviser, too. I have benefitted a lot from Paul Clayton's book Health Defense. second edition - I believe there may soon be a third. Very detailed look at the interactions between nutrients, even at the biochemical level, but understandable. very practical, with lots of chapters on certain ailments and how nutrition affects them. check out drpaulclayton.com, also healthdefense.com. He has a new book, Food or Pharma, which looks interesting. His info is v. well referenced and generally sounds quite unbiased, except for a couple of outlandish references to Nestle! which make me suspect he may do some work for them also. all the best.
