Low-Carb Diet Reduces GERD Acid Exposure by 37%: RCT Results
Can Changing Your Carbohydrate Intake Reduce GERD Symptoms?
Yes, modifying both the amount and type of dietary carbohydrates can significantly reduce esophageal acid exposure and GERD symptoms. This randomized controlled trial demonstrated that a low-carbohydrate diet reduced acid exposure time by 37% and improved symptom scores by 44% compared to a standard diet over just 4 weeks.
Dr. Kumar’s Take
This RCT provides compelling evidence that diet modification can be as effective as medication for many GERD patients. A 37% reduction in acid exposure is clinically meaningful - that’s similar to what we see with proton pump inhibitors. What’s particularly impressive is the rapid improvement within 4 weeks. This gives patients a concrete, medication-free option that addresses the root cause rather than just suppressing acid production.
