Hi Solange, if you use the recommended size baking pan, the bread will be the proper height. If you use a pan that is bigger than the one I used, your bread will rise, but it won’t fill the pan to the right height. Here’s an example that might help –if you place 1/2 cup of water in a 1/2 measuring cup it will be 100% full to the top of the cup. If you put the same 1/2 cup of water in a 1 cup measuring cup it will only fill it 50% and will only be 1/2 full in height. That’s why a loaf pan that is too large doesn’t work for this recipe when it comes to the height of the loaf :-)
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
