vegan, vegetarian or organic?

I can tell I am going to have to see a nutritionist as I am getting major info overload on what to eat and what not to eat.  I have found tons of vegan, vegetarian, cancer cookbooks and its hard to find recipes that look good enough to make.  I don't even know what some of the ingredients are!  All I know is that I have to clean up my act.  Everything that I have been eating over the last 30 years is bad, bad, bad.  Fast food, processed foods, fried foods, sugar, etc.  All the diet crap I've been putting in my system, including diet pills, supplements, diet bars, shakes, sugar substitutes etc...all bad. All the stuff I used to clean my house, my clothes, my face, hair, body, etc...  all could have contributed to my illness.  I'm not going to get rid of this all at once but I can tell you that I will gradually replace it with organic, natural products.  I'm going to Wegmans tomorrow to get started with the food portion.  nothing but organic fruits, veggies, whole grains, etc...
