It is a common belief that coffee acid causes stomach issues. But advice can get confusing when it is inconsistent. I ran across an article recently, about what to do if coffee bothers your stomach, and was shocked at one doctor's advice. Right after stating that coffee acid contributes to stomach issues he then recommended drinking lemon juice before your coffee. Lemon Juice? Doesn't that have high acid content? Take a look at any pH chart to compare the two and it is clear that lemon juice is far more acidic than coffee. It is unfortunate that the advice we receive at times is inconsistent. So, we have to pay attention and seek out solutions that have been tested, rather than accepting the common myth. While some people have claimed that lemon water helps with stomach issues, WebMD tells us in this article that there is NO research that supports the claim that it helps reduce stomach acid. On the other hand, Southern Grinds premium coffee actually reduces the secretion of stomach acid so you can enjoy your coffee again.
