Grass Fed Cows Vs Grain Fed Cows? (For Their Milk) in Coping with Celiac Disease Posted February 14, 2015 · Report to Admin Wow, a lot of information here. I love how you all got off topic because of poop lol! By what you guys say, I know I am 100% lactose intolerant. I can eat cheese and what not, but the milk makes me the sickest. I am going to try different milks like the lactose free one etc. just to see how it reacts to me. Thank you guys for your information. I very much appreciate it.
