Hi Suzanne and everyone -I don't think that you have to give up the foods that are nutritious and that you enjoy. People have been asking me what I meant by "processed foods". I tend to follow Michael Pollan's test -if your Grandmother or Great-grandmother wouldn't recognize it -don't eat it!

Generally speaking, processed foods are any foods that have been altered from their natural state. I believe the original blogger was encouraging people to eat more raw foods and eliminate fast food. Anything that has had to be fortified or enriched with vitamins artificially, should be avoided.

I just read an article from a food nutritionist at UC Davis who listed the top 10 superfoods to eat. They are:

Almonds, Blueberries,Tomatoes, Salmon, yougart, whole grains, Broccoli, Olive Oil, Mushrooms and Spinach.

Incidently, Dan ad I haven't been able to adhere to the 30 day processed food challenge. We were OK for two weeks , but I have a weakness for Chocolate Extreme Blizzards....
