Yeah I usually say that I'm into traditional foods nutrition, because if I just say whole foods people are like "yeah...so you like soymilk and lowfat things? blablabla" and because there are also whole food vegans. I usually have to end up explaining it at least briefly because if I say "yeah I'm into nutrition" people automatically think I mean lowfat, etc. I get confused looks when say I'm into and discuss nutrition with the Chiropractor I work with who is also into "nutrition" (a soy isolate protein shake because he lifts weight...sweetened with sucralose blah!) and then they offer me soymilk and I politely refuse it.
I'm still trying to explain it to a friend of mine. I say I'm into nutrition and she'll say, "I'm so jealous...you're so skinny...teach me" and then in the next breath she says "dairy is my biggest downfall! my husband (a great cook) cooks with butter and cream". To which I say, "I use lots of butter and cream" and she just looks confused. I look at her kitchen and see white flour pasta, bread and cereal with soymilk and realize those are her downfall, not dairy products.
Slowly she is getting it hehe.
