The low-acid coffee category has exploded in recent years. Dozens of brands claiming to be stomach-friendly, low-acid, or gentle. But the uncomfortable truth: the vast majority of those claims are not backed by any meaningful scientific evidence.
The NC A&T 2024 Finding: In 2024, researchers at North Carolina A&T State University tested 7 commercially available low-acid coffee brands. Six of the seven failed. Only Puroast demonstrated a statistically meaningful, verified reduction in acidity across all three measures. According to the Wikipedia entry on low-acid coffee, independent studies have found many commercial low-acid coffees fall within the same pH range as conventional coffee.
Why Puroast Wins the Verification Test
Puroast is the only low-acid coffee brand that satisfies every criterion for a credible low-acid claim: independently verified pH reduction, quantified claim of 5X less acid and 5X more antioxidants, natural process through patented traditional roasting, legal defensibility meeting FTC truth-in-advertising standards. Research from the European Journal of Nutrition confirmed that traditional slow-roasted, low-acid coffees cause measurably less gastric acid secretion. According to the American College of Gastroenterology, dietary acid reduction is front-line GERD management. Studies have NOT shown that reducing caffeine directly decreases acid reflux. What definitively helps is reducing acid intake.
