go to Joe Trader's or Whole Food. They are healthy grocery stores.
I am aware about lactose because I am lactose user for 17 years and use less dairy needs. Watch what you eat and drink.... like milk in your cereal and eat chesseburger or anything like that.
Okay - about my hospitalized last September 2000 (8 years ago) in Dallas, I have no food in my stomach and keep vomited, ofc BM often. My parents took me to ER then put me in bed for two days then go home with doctor's comments about diet food list. Now I can not find that paper anymore after I moved here St Louis.
Also, I had surgery on my stomach when I was 11 years old...long time ago, not need another surgery because of that plm. Now, I just had plm with acid inside there so I think it is just GERM from something in food.
I found out I had Lactose Intolerance when I was 21 and still am for 17 years now. Watch what you eat and drink....
