A more controversial argument for why legumes and common grains are avoided is because of their high phytic acid content, which is thought to reduce the absorption of certain nutrients like iron zinc and calcium (6). However, phytic acid is also found in many paleo approved foods (like almonds and hazelnuts), and is associated with some health benefits - like protective benefits against kidney stones, antioxidant properties and a suggested link to lower risk for colon cancer (7,8,9). Bottom line, there really isn't any evidenced based reason to avoid these foods because of phytic acid. 
This is the best keto bread I have ever made! By far! My bread was a little flat, but I think my baking powder needs to be replaced. I did make two substitutions with this recipe. I replaced egg whites with whole eggs, and ghee with coconut oil. Everything else, I already had on hand. I will definitely make this again and play with it a little. Really delicious bread.
"Loren Cordain's extensive research demonstrates how modern westernized diets drastically depart from the original diet humans consumed for millions of years. In The Paleo Diet and The Paleo Diet Cookbook, Dr. Cordain shows how diets high in grains, dairy, vegetable oils, salt, and refined sugars are at odds with our genetic legacy and then shares his uncomplicated strategy for losing weight and getting healthy."
Like a lot of others, mine didn’t rise as much as I had hoped, so the crumb is a bit more dense. Next time, I’ll give it longer than an hour and see if that helps. My loaf pan is also a bit bigger, so I think I’ll do 1.5 times the recipe next time for a larger slice of bread as mine was very short and squat, lol. Overall though, I’m thrilled. This is by far the best grain-free bread I’ve ever tasted!
I know that soy can cause inflammation and if you are not using soy free eggs, that could be part of the cause. It may not be the actual egg but the soy that is the problem. just a thought. Here is an article that has some interesting info on soy. http://articles.mercola.com/sites/articles/archive/2012/07/29/soy-effects-on-women.aspx?e_cid=20120729_SNL_Art_1
