Always eating in a hurry? Shoveling food down is also a no-no, if you want to tame heartburn. Leslie Bonci, MPH, RD, CSSD, director of sports nutrition at the University of Pittsburgh Medical Center, says the three G's -- grab, gulp, and go -- don't make for good digestion and can make GERD (gastroesophageal reflux disease) symptoms more likely. Heartburn is a GERD symptom. So slow down when you eat if you're concerned about heartburn symptoms.
