How about the perpetual bovine lactose intolerant gene? Some babies can only tolerate human milk.

I say that the study is defective.

True enough, but isn't the problem that those kids mount an autoimmune response against a specific protein in cow's milk?

Different gene.

More worrisome is celiac syndrome ~ there you have a gene that triggers an autoimmune response to a protein in wheat, barley and rye called gluten.

This one seems to have appeared in populations isolated in the trackless wasteland of the Great White North.

Here's your diet if you are dealing with any of these things ~ reindeer, seal and pine needles ~ maybe a chunk of lichen in a hot tea every now and then.

Love dem seal!
