Flavours in Breastmilk

I found this article very interesting. The fact that their research showed that it only takes at the most 8 hours for the taste to disappear is interesting in relation to Saana's response to food I've eaten.
When doing the food challenges I can always tell if there is a problem with the food within 12-18 hours. IF she hasn't reacted after 24 hours I can pretty much be assured that the food is not a problem for her.
I must admit I've always suspected that breastfeeding helps develop a babies tolerance to flavours. I also think that a broad diet while pregnant help to develop the babies tolerance to different foods, but I don't know how you would research that idea.
