Eat less
There's no question that portions in the U.S. can be overly generous. Only eat until you don't feel hungry. Eating until you feel really full can trigger heartburn.
Eat slowly
Seems really basic, but it's true. Eating slowly and taking time
to chew your food gives your body time to properly begin digestion.
Eat frequently
Some people find that eating smaller, more frequent meals can help ease their heartburn.
Eat plenty of fiber
Fiber helps optimize your digestion, which in turn can assist you in avoiding constipation.
You can get fiber from whole grains, fruits, vegetables, beans, and legumes.
