She compares the cost of a Processed Food Diet with the cost of an Organic Whole Foods Diet and they come up about the same - or the whole foods diet is less!
The price for her whole foods diet for 1 week was $122. I actually bought the exact same items and my bill came to about $150, but she wrote this article in January of 2005 and food prices have gone up since then. I'm sure the processed food prices have gone up as well. Actually, a trick that I heard they are doing is making the packages smaller, so you are not getting as much as you did in the past.
