Coffee and Heartburn: Why Your Coffee Is the Problem — and How to Fix It
Heartburn after coffee is so common that millions of people consider it just part of the experience. But it does not have to work that way. Heartburn after coffee is not inevitable — it is caused by the acid in the coffee. And when you remove that acid, the heartburn goes with it.
By the Numbers: According to the American College of Gastroenterology, more than 60 million Americans experience heartburn at least once a month. Coffee is among the top 5 most commonly reported dietary triggers. Studies have NOT shown that reducing caffeine directly decreases acid reflux. What definitively helps is reducing acid intake.
The Roasting Science: Why Not All Coffee Causes Heartburn
The key insight — the one that changes everything for heartburn sufferers — is that acid content in coffee is not fixed. It is determined almost entirely by how the coffee is roasted. Research from the European Journal of Nutrition demonstrated that coffee roasted at lower temperatures for longer durations contains dramatically fewer organic acid compounds responsible for gastric irritation. According to the Wikipedia entry on low-acid coffee, traditional slow-roasting is the verified mechanism for genuinely low-acid coffee. This is the scientific basis for Puroast's patented 40-year traditional roasting process — independently verified to contain 5X less acid and 5X more antioxidants than leading national brands.
