Ground Roasted Coffee

why is it that even folgers simply smooth ground roast coffee upsets my stomach when i like to put a ton of it?

in my morning coffee since i like to take it black/straight, how come also kava instant coffee brand which is "acid neutralized" also makes my stomach upset a while after drinking it even it claims to be at least 50% less acid than conventional instant coffee? my mom told me to put milk/cream/coffeemate so my stomach will no longer get irritated by rich, pure, strong, bitter coffee which i just love but my stomach cannot handle it anymore after 10 years of bitter, strong coffee which i really love. why would the folgers simply smooth version not be good as to avoid getting my stomach upset? do i have to alltogether give up drinking my coffee black? can a doctor please tell me what to do so i can avoid gastritits/ulcers in my stomach for the distant future? why is it that acid neutralized coffee is no longer working for me? a physician please........... thank you.

Miz Kitty is on to something. Its not the acid in the coffee that makes your stomach all messed up. it's the pesticides and chemical they use to grow the beans. the commercial brands usually use harmful chemicals to treat their beans, which commonly causes upset stomachs in for people of all ages. there are some good organic coffees out there, but be warned, not all of them taste the same. either way, the best and easiest way to find good coffee, is at a local gourmet coffee shop. they will be able to help you select and find a good coffee.
good luck

Natural occurring caffeine in coffee is not like the synthetic crap thats in energy drinks. i used to think that too much caffeine was the cause of my upset stomach, but its not. i used to order a a drink with 6 shots of espresso. the barista always teased me, telling me im going to haave a heart attack. in fact, thats what she ended up calling it my 6 shot heart attack. LOL. i would drink two of those a day. yummy. i would still be enjoying this drink, but the place ended up going out of business. =(
point being, if the cafffeine content was an issue, the 12 shots in a 12 hour period should have put me in the hospital. LOL. i was one wired puppy though. HAHAHA
