Gastroenterologist Questions Heartburn

Does excess protein intake cause acidity?

I am working out a lot more these days and for protein I end up eating a lot of beans and grains. I've also been noticing a lot of heartburn lately. Could my food be the cause of my acidity? Or is it the exercise?

The amount of acid made is fairly steady from day to day, and it normally increases when a meal is eaten. If you experience more heartburn, this doesn't mean that you are making more acid than usual. It means that the acid being made is going where it shouldn't (i.e., into the esophagus). In general, to reduce acid reflux, eat lighter meals, avoid overeating, don't lie down soon after eating, avoid caffeine, alcohol. There are many factors that can cause more heartburn, but protein-rich foods are not a significant cause. Use pepcid or nexium pills if heartburn is bothering you a lot. If it becomes a chronic issue, then it may help to see a GI doctor.
Avoid exercising after meals, especially those exercises that increase intra-abdominal pressure.

Beans and grams are ok after exercise but remember they’re high in lectins.

High protein and high fat containing foods tend to remain in the stomach for a longer time.
