What is GERD?
You have probably heard of acid reflux, or gastroesophageal reflux (GER), which is the backward flow of stomach acid into the esophagus. What you may not have heard, however, is that severe acid reflux can lead to gastroesophageal reflux disease, or GERD.
GERD is a common disease that affects about 20% of the population, and the most common symptom is frequent heartburn. Foods known to trigger heartburn delay the digestive process, letting food sit in the stomach longer. They also cause the esophageal sphincter to relax, which is what allows stomach acid to back up (reflux) into the esophagus.
Eliminating certain foods from your diet is one of the best ways to mitigate GERD symptoms. An elimination diet can also be used to learn whether or not certain foods cause or aggravate your symptoms. This is important because every stomach is different. A food that causes GERD symptoms for one person may not cause them for someone else. It follows that there is considerable controversy over which foods actually cause symptoms. That said, there are a few foods that everyone agrees are common triggers. Here is what to avoid when buying protein powder.
Dairy-based protein powders can cause acid reflux. Common dairy-based protein powders include casein and whey protein powder, both of which are byproducts of cheese and yogurt production. If your casein or whey protein powder causes acne or stomach pain, it is time to look for a new protein powder. Fortunately, going dairy-free is easier than ever. Unfortunately, not all dairy-free protein powders are created equal.
