Some smoothies do give me heartburn most of the time. When I had my Esophageal pHmetry doctors told me to eat/drink anything that caused me heartburn and I did. I drank 3 berry smoothies, which usually makes me feel like I could spit fire, and my stomach handled it well. The pHmetry didn't show any spikes in acidity, everything was normal.
