What are common sources of acid in our diet?

Black coffee, herbal tea, fruit juice, wine, sparkling water, water with lemon, soft drinks, sports drinks and many alcoholic beverages are acidic. It is best to drink these over a short period of time, avoid sipping them and to swish your mouth with plain water upon finishing them.  Most fruit and vegetables are also acidic.  The FDA list of “Approximate pH of Foods and Food Products” is a great resource for determining the acidity of a food.   Many of them are important sources of nutrients and should be an integral part of our diet.  It is important to eat them over a short period of time and not to brush with toothpaste within an hour after their consumption.
