To jump on the homeopathy bunny trail....
Actual homeopathy is a load of crock, but what gets me is when actual medicine gets labelled "homeopathic" simply because it is not a standard-chemical-medicine.
Those Hyland's teething tablets actually work. I don't know why. How can that actually be "homeopathic"?
And what really got me recently was I got some activated charcoal caps because my husband came down with food poisoning. On the front of the box it was labelled "Homeopathic"! what? Activated charcoal is not "homeopathic"! In Europe doctors will write you a script for it!
To the OP: If you go MD you could get certified in nutrition by one of the Paleo-type groups, then do a combo-practice. It starts with food, after all, and stuff.
