Having GI distress after a cup of coffee is more than enough reason for some folks to swear off the stuff. Like so many things around food and how our bodies process it, the subject of what causes such distress is often up for debate. Edwin Martinez of Hario USA & Finca Vista Hermosa posited that the negative reactions to coffee could be based in rancid oils or over-roasted beans. Some folks think that maybe it’s just sheer acidity in the bean itself.
