Interesting notion. I was told long ago that most women eat peanut butter when depressed. At that time the doctors did not know why this might be so, however, I believe that our bodies know what they need. Craving are often a sign of something that is missing. Maybe women (or men) who crave peanuts/peanut butter or the other things you mentioned do so because the body know what is needed. don't forget how to laugh Marling
