If you get off dairy read the ingrediants of the non dairy milks. If you see alot of gums you will have gas and bloating. There's a video on utube that shows you how to make your own almond milk in about a minute or 2. Just raw organic almonds, almond butter and water.
Read ingrediants of everything because there are so many bad additives you must be careful. Also as far as I've heard all soy is sprayed just like wheat.
There's also videos that check the ingrediants for you and tell you what is safe
I believe that most of our food is garbage due to depleted soil not to mention the garbage, cancer causing fillers. This is what causes alot of health problems. As well as if used correctly, food and especially herbs are the best medicine. Buy organic or better yet grow your own.
