Love to Eat| Here’s to French Roast coffee … and espresso and all the bold blend coffees at Starbuck’s. Stomach irritation prevents 2 in 10 people from enjoying the benefits of a great cup of coffee. If your mother makes it weak, so as not to upset your stomach, in this rare case, mom may be wrong.
Until now, scientists knew that some chemicals in coffee stimulated acid production but not which ones. In the process of identifying those chemicals, researchers unexpectedly discovered N-methylpyridium (NMP), which seems to block the ability of the stomach cells to produce hydrochloric acid and could provide a way to reduce or avoid stomach irritation.
Since NMP is generated only upon roasting and not found in raw coffee beans, darker-roasted coffees contain higher amounts of this stomach-friendly coffee ingredient. Dark- roasted coffee can potentially contain up to twice as much of the ingredient as light-roasted coffees, but its levels can vary widely depending on the variety of coffee bean and the roasting method, Somoza noted. via Science Daily
