I just looked this up because I realized that I really didn't know for sure.
But it looks to me like if it isn't raw meat, fruit or vegetables, it is
processed.

Nuts out of the shell are processed. Milk is processed. So are cheese and
yogurt. If it's frozen? It's processed. Even if it is simply vegetables
or fruit with nothing added. Flour would be processed. So would rice and
pasta of all kinds. Anything in a can is processed. Dried foods are
processed. If you cook it? You've processed it.

So I'd be willing to bet that unless you are a raw vegan whole foodist, you
are eating processed foods!
