<p>I personally couldn't taste any difference between decaf and regular coffee but depends on the brand. According to some resources is decaf the biggest source of antioxidants in the western diet and it has positive impact on health if you drink 2-3 cups per day. From my personal experience, you can drink probably as much decaf as you want since it doesn't have any negative side effects, regarding regular coffee you might get breath problems and high blood pressure if you drink too much. There are lot of good brands of decaf where you don't taste any difference between it and regular coffee.</p>

<p>I have read that actually decafs have caffeine but way less than regulars. So there could be no reactions at all. Espresso decaffeinated is a very good solution since it has a nice taste &amp; better quality effects on body than instant ones for example. Whether drinking regular coffee or not, make sure you drink enough water, it helps.</p>

Please elaborate on your argument. You make quite a few claims, but they lack backing up. Adding some references from well-established sources goes a long way.

Finding a coffee with <em>both</em> properties may be a good reason to get familiar with your local roaster instead of buying at the supermarket.</p>

<p>Is it caffeine or chlorogenic acid the ingredients of coffee stimulating the stomach?</p>

<p>If it's chlorogenic acid, do you have coffee without chlorogenic acid? Or how to choose coffee with less chlorogenic acid?</p>

<p>In short, love the taste of coffee, but wouldn't the reaction on the body, that is, no diarrhea, frequent urination nor excitement.</p>

Is it caffeine or chlorogenic acid the ingredients of coffee stimulating the stomach?

If it's chlorogenic acid, do you have coffee without chlorogenic acid? Or how to choose coffee with less chlorogenic acid?

In short, love the taste of coffee, but wouldn't the reaction on the body, that is, no diarrhea, frequent urination nor excitement.

*Disclaimer:  
I am neither a doctor nor a chemist.  
The following statements rely heavily on the [German Wikipedia article on chlorogenic acid](https://de.wikipedia.org/wiki/Chlorogens%C3%A4ure) and some other sources that are typically considered trustworthy (e.g. [PubChem](https://pubchemdocs.ncbi.nlm.nih.gov/about) and others citing studies.

So we have two suspects that may or may not be responsible for stimulating your digestive system.

**Chlorogenic acid** sounds like a good candidate for stomach issues (being an acid), but in animal testings it actually helped against ulcers and there are no indicators of other plants containing chlorogenic acid causing problems.
