Acid reflux will most of the time show symptoms of heartburn so stay away from spicy foods like hot peppers and hot wings. Also, acidy foods like tomatoes, onions, and citrus foods are important to stay away from. Foods with high amounts of fat can relax the muscle that blocks the acid from coming up, so try to steer clear of fast food as well. Finally, if you can drink water compared to tea, soda, or Hot Chocolate your body will have a much easier time handling acid reflux.
