I like spicy food, very spicy hot food and I don't have stomach problems, no acid, no reflux, no up-set stomach. How about you,(?) close to 18 million people in the U.S. have some form of diagnosed stomach problem and of course that amounts to many millions in money/profits for the medical. Now, to make the entire stomach thing more of a challenge, there are some real problems with taking prescribed and non-prescribed stomach (acid reflux) pills/medications (purple, or what ever color your medication is).
This is what "I" do: I eat real, Plain Yogurt, if I notice my stomach not feeling as "good" as usual, I take some Aloe Vera juice, or I chew some plain original Papaya Enzyme tablets, I also like Ginger Tea (good stuff). What you do is up to you. Also, I have not had a prescription medication/drug for at least 35 years. Oh, I just about didn't mention the most important part, -- I eat real, natural food, with very very little crap food. Empower yourself and, why not feel good! Bob
