I am not a doctor, nor a nutritionist (but I did study nutrition for several years)and recommend Dairy and other Calcium rich foods, too. The Calcium neutralizes the acid. (It´s the reverse of removing calcium deposits with vinegar) ;-)
Calcium rich foods are: Dark Leafy greens like spinach, kale, turnips, and collard greens, Rye bread, canned Salmon, Cheese, Yogurt, Milk, Sardines, Fortified cereals such as Total, Raisin Bran, Corn Flakes (They have a lot of calcium in one serving.), Soybeans, Fortified soymilk or almond milk (Not all soymilk is a good source of calcium, so it's best to check the label.)
Stay away from the Fortified orange juice, as it contains a lot of acid.
Eat smaller more frequent meals, and drink your water.
