As you may know drinking alcohol does not help your stomach in any way.It also depletes your system of vital minerals needed for good health.
It depend what you think bad food is??? Some people are more sensitive than others to foods that irritate your stomach but foods like fried food, spicey, coffee, sodas or sugary foods cause the stomach to produce more acid and are not good for your problem!!
The best foods are the things that are easy to digest like yogurt, kefir, rice, oatmeal, chicken & turkey. Just the more bland type foods. Red meat is just more difficult to digest.
