Hello :)
I think I have the same diet as you- maybe a tiny bit stricter. I only eat vegetables, fruit, nuts and seeds. I travel alot (but never to the US)and I always find something to eat. Though sometimes I go days just living on fruit - which isn't so bad. Anyway, this diet really pays off performance wise. When I do intensive sports I don't ever feel it the next day I like I used to. My eyes are brighter and I never feel 'really hungry' only slightly hungry even if I've missed two meals.
