I'm a bit unclear on the definition of processed foods as well.

We've never purchased a tv dinner, all food is cleaned, prepped and cooked from scratch, even home made fries, with the exception of hamburger night and twice a month take out...

Lol, idk anyone who doesn't chop their own onions, make their own bolognaise or even white sauce.

Buuut, we are not of money and do not shop in the purely organic / gluten free sections either... so I'm not sure if I eat processed food.

That being said, if my diet does not and never has contained processed food, I can't comment on the mood thing, but on the flip side it looks like I could seemingly have been off wayyy worse, had I a different diet.
