The top 10 most acidic foods include milk, lemons, limes, grapefruit, apples, coffee, wine, soda, pickles and red meat. Over time, these foods build up acid in the body, wear out teeth enamel, and contribute to damaging the kidneys and liver.
Something acidic is defined as having a pH less than 7. The pH scale is used to measure how acidic or basic something is and ranges from 0-14. A pH of 7 is considered a neutral and anything between 7 and 14 as basic, according to the United States Environmental Protection Agency. Other acidic non-food items include car batteries, acid rain, peat moss, and even stomach acid.
Many fruits, including lemons and grapefruit, are considered acidic because they naturally contain citric acid, while other drinks like soda contain citric acid that is added on purpose to give the product its signature bite of flavor. The way to combat highly acidic foods and prevent an excess of acid build up in the body is to consume foods or beverages that are either neutral or basic in pH. Those foods and drinks include leafy greens like kale and spinach, potatoes, bananas, and many others, as stated by the Dr. Oz Show.
