Is it alright to eat popcorn with acid reflux?

Depends on how made: (acid reflux is a common cause of feeling of heartburn.) if air popped & eaten in moderation, popcorn likely won't cause problems. If buttered, cheesy, or cooked in oil, more likely to increase acid reflux. Everyone is different; if it seems to worsen heartburn or acid brash, avoid it. Avoid:fatty/greasy/oily foods, cheese, peppermint, chocolate, alcohol, tomatoes, caffeine, citrus, overeating.
