Citric acid is a nutrient found in citrus fruits such as lemons, limes and oranges. Citric acid has many health benefits: it prevents kidney stones, regulates digestion and supplies the body with antioxidants. However, if you have a citric acid intolerance, or other health problems related to citric acid, eating it may be harmful to you. Since citric acid is found in so many foods, it may seem difficult to avoid, but with the right knowledge, you can easily avoid the foods that will cause you trouble.
Don't eat fruits that are sour or tart. The sour taste comes from the natural citric acid in the fruit. Stay away from lemons, limes, oranges, strawberries, cranberries, raspberries and pineapple. Bananas, even though not tart when ripened, also have citric acid. Stay away from juices, desserts and alcoholic beverages that contain any of these fruits.
Avoid soft drinks. Sodas and other carbonated beverages contain citric acid to create a tangy flavour and to maintain carbonation.
Stay away from wine. Citric acid is added to wine to keep sediment from forming at the bottom of the bottle.
Read the label on any processed foods that you buy. Citric acid is a natural preservative used in canned foods, candies, jams, jellies, gelatin desserts and processed cheese.
