The lists of vegetables, fruits and grains on this site have been edited to ones that most people have a reasonable chance of acquiring provided they have access to a specialty food store or by ordering online.
All the lists are fairly comprehensive. Some vegetables, fruits and grains have been omitted because they are not commercially available or are only available in very limited areas and as such are beyond the reach of most consumers. These lists are meant to be easy to use without the clutter of items most people won't be able to acquire.
