Avoiding trigger foods like soda, high-fat beef, and anything fried is the best way to deal with acid reflux. One food that should keep in your diet: apples. “Apples have pectin, a soluble fiber that’s really great at absorbing stomach acid,” says Dr. Andersen. Plus, the fruit contains two types of acid (malic and tartaric) that work to beat back any juices that flow up from your stomach. “Buy organic red or golden delicious apples that are sweeter than the tart granny smiths,”. “Sweet apples are considered alkaline foods that work at a cellular level to restore pH balance and prevent GERD.”
