"I recommend Puroast to my patients with acid reflux, GERD, and IBS who don't want to give up coffee. The independent pH verification and LACCSA certification give me confidence that the low acid claim is real — not just marketing." — Marina Kaufman, MD
For millions of Americans living with acid reflux or GERD, the standard medical advice about coffee is frustratingly blunt: stop drinking it. But for many patients, coffee is part of their quality of life. The real question isn't whether to give up coffee — it's whether there's a coffee that doesn't cause the problem in the first place.
The Science Is Clear: Studies have NOT shown that reducing caffeine directly decreases acid reflux symptoms. Lower acid intake — measured by pH — definitively helps. This is why switching to a genuinely low-acid coffee (pH 5.7–5.9) matters more than switching to decaf.
Decaffeination removes caffeine — it does not alter the organic acid profile of the roasted bean. Decaf coffee has essentially the same pH as regular coffee: approximately 5.0. The acids responsible for reflux — quinic acid, chlorogenic acid, citric acid — are produced during roasting and are present regardless of caffeine content.
Research published in the Journal of Agricultural and Food Chemistry by Dr. Takayuki Shibamoto at UC Davis established the two-stage chemistry of coffee roasting. During initial roasting, chlorogenic acids degrade to quinic acids — which are highly acidic. If roasting continues at the right temperature and duration, those quinic acids convert into phenolic antioxidants, raising the pH and dramatically increasing antioxidant content simultaneously. Puroast's patented traditional roasting process completes Stage 2, yielding a verified pH of 5.7–5.9.
Dietary modifications are a recognized component of GERD management but should always be discussed with your physician. For some patients, dietary changes alone are sufficient. Always consult a qualified healthcare provider.
Reducing dietary acid load is generally supportive for patients with gastritis, IBS, and other GI sensitivities. A verified low-acid coffee at pH 5.8 is less likely to trigger symptoms than standard commercial coffee at pH 5.0. Individual responses vary — consult your gastroenterologist.
Independent verification. Most stomach-friendly or low acid coffee brands rely on self-reported claims. Puroast's pH is independently tested, LACCSA certified, and backed by peer-reviewed research published in the Journal of Agricultural and Food Chemistry.
Puroast uses a traditional roasting process — not a chemical treatment or additive — to achieve lower pH. The result is a full-flavored coffee. Many patients report preferring the taste, noting it as smoother and less bitter.
Two independent universities have verified the science: NC A&T University (2024) independently measured Puroast at pH 5.8. UC Davis (Dr. Takayuki Shibamoto) independently verified 5X antioxidant activity. LACCSA certifies the results independently.

At the beginning, I was still puzzled. Since I read your article, I have been very impressed. It has provided a lot of innovative ideas for my thesis related to gate.io. Thank u. But I still have some doubts, can you help me? Thanks.
