Gluten in Human Milk (an potentially other animal milk)

I thought I'd post this interesting article I came across:

https://www.glutenfreesociety.org/gluten-free-society-blog/gluten-gliadin-found-in-breast-milk/

I was wondering if gliadin passes into breast milk and it appears that it does. I had no idea. So this article is sort of presenting the question of gliadin passing through to grain-fed animals' milk. Here's an exerpt:

Is this one of the reasons that so many do well on a gluten free/casein free diet?  Is this why so many people tolerate European dairy products vs. American dairy products? (Europeans typically produce their dairy from pasture raised animals).  Is this why refractory celiac disease is present in such a large percentage of the diagnosed celiac population?  Consider the maelstrom of detrimental reactions to gluten loaded dairy products in those with gluten sensitivity.  

I'm thinking cows and other milk animals are eating mostly corn & soy but I've also read about them chowing down on "waste" products from random food manufacturers (candy bars, for example... poor cows!) so there's that source of contamination.

Anyway, the wheels are turning in my head now because I'm trying to figure out why DD is breaking out in eczema splotches after a summer of beautifully clear skin - at long last! The only change in her diet has been through school. She's now eating stuff like crackers and pretzels 3x/wk where we had been mostly grain-free since February. 

And a vent for your entertainment: why the heck can't people feed kids something besides crackers??!!? Seriously, you would think it's the only toddler snack food that exists on this green earth.
