I looked at the Diamond Naturals, and I personally think lentils are as much or more of a problem than peas. The 4 Health Salmon & Potato (also has barley and millet) seems like a better food to me. The 4 Health Whitefish & Potato Grain Free has more peas than American Journey. I just noticed that AJ has beet pulp and FOS for prebiotics, so that could be another reason Atlas did better with it. All the 4 Health foods have pre/probiotics. I believe I saw on the Reviews side that Diamond manufactures the 4 Health food for TSC. Also, Diamond has a sensitive food like the 4 Health–it may be the same one.
I did look at the limited ingredient foods, and all the ones I found were basically as high as NB or higher.
I too am concerned with the FDA warning and think it needs to be taken very seriously. There is a lady on DFA who was feeding her pup Zignature Zssentials and its taurine level was below critical. I now have my allergy girl on a grain inclusive food, and I am going to start working on trying to find a food for the other one. I am thinking of trying ProPlan or 4 Health for her.
Cooking legumes at home is a different process and that will not help as to whether he can handle them in a kibble. I personally would go with a food that has no more than one legume, and you may want to consider a grain inclusive food. His gut is in a different place now than when you had all the trouble previously. When you do start to transition again, if he starts to get soft, I would also add a good pet probiotic with prebiotics and see if that makes any difference.
