Did you know that some fruits commonly considered to be acidic actually have an alkalizing effect on the body? Fruits such as lemons, oranges, and pineapples all contain large amounts of citric acid, a chemical that can bring a food’s pH level lower than 3. This means that citrus acid in fruits can actually be more acidic than stomach acid. However, food cannot be considered acidic to the body based solely on its pH before it enters the body. Once food is digested, the acidic or alkaline materials may be metabolized in different ways. The acidic or alkaline effect of the food on the body is called ‘ash’ pH.
Citric acid is considered a very weak acid when digested. In other words, it does not have a very strong effect on the body. Many fruits, such as lemons, actually have an alkalizing effect on the body once they are metabolized. Oranges, strawberries, grapefruit and many other fruits are considered alkaline once metabolized. However some fruits, especially heavily processed fruits, do not metabolize all of their acid, and they can be acid-forming within the body. Some websites offer a listing to show which foods are alkaline and which ones are acidic, but make sure to find one that is credible. You may find that a few of these websites are in disagreement.
