Acidic foods are those that have a low pH level, typically below 7. These foods can taste sour and include items like citrus fruits, vinegar, and tomatoes. They are often rich in vitamins and can enhance the flavor of dishes, making them popular in various cuisines. Consuming acidic foods can have both benefits and drawbacks. On one hand, they can aid in digestion and provide essential nutrients. On the other hand, excessive intake may lead to issues like acid reflux or tooth enamel erosion. Moderation is key to enjoying their benefits while minimizing potential harm.
