I saw this study recently too and there was some debate about it on Facebook. I have no idea what's true or not but some critics of this study said that one of the big name peanut companies actually funded the study and excluded any kids that were at high risk of developing peanut allergies. There was a lot of talk that the results were skewed and that there they actually tested kids for potential allergies and excluded anyone who tested positive before the study even started. Again, I don't know what's true or not, I'm just repeating what I read.
