I'll have to say i agree with the posts following mine and i was actually thinking of going on and on explaining how real lemon squeezed into water would still qualify as a 'whole' food. but i was trying not to go on and on....
I was wanting to illustrate the point that
physical alterations to a whole food can still fit into most whole foods diets. Alterations such as purreeing , freezing, boiling, frying in a good type of oil and yes apple sauce

I'm not sure what i was saying when i typed in "saucing" as not being a whole food, but i think i may have been thinking either commercial applesauces with perservative and other additives or maybe apple pie filling type sauce.
For the sake of simplifying, a 'whole' food in it's purest form is a food not altered by man. (ie. the produce section).
but other than that, if you look at a label say of frozen green beans, and the ingredients reads :
Ingredients: green beans
then most people will agree it's still a whole food.
In the case of commercial apple sauce, if it says something along the lines of:
Ingredients: apples, water
or:
Ingredients: apples, water, cinnamon
i will consider that a whole food. but when the ingredients start to include preservatives, flavor enhancers, color enhancers, i definitely don't see it as a whole food any longer.
Personally, i don't like to see vitamins or anything added either, although it depends on the source of the vitamins, if it's a brand i trust, if i think the supplimental vitamins are necessary. I may still include it in my diet, but i won't neccessarily regard it as the wholest of foods any longer.
