Avoid pairing acidic fruits like grapefruits and strawberries, as well as sub-acidic meals like apples, pomegranates, and peaches, with sweet fruits like bananas and raisins to help digestion. You can, however, combine acidic and sub-acidic fruits. For example, you could eat a banana and a handful of sunflower seeds at the same time. Bananas are a good source of fiber, vitamin B6, magnesium, and potassium. They're also a good source of energy (calories). Raisins are a type of fruit that is grown in clusters on a vine or tree. They have a tart flavor and soft texture when dry. They can be red, white, or black, but only black raisins contain antioxidants. You can eat bananas and raisins together. This article explains how. First, it's important to understand that your body processes foods based on their acidity. Foods are either acidic or alkaline. Acids include citrus fruits, tomatoes, and vinegar. Alkaline foods include potatoes, carrots, and beans. Your body is made up of both acids and alkalis, so it needs some balance between them if it is to function properly. Too much acid or too much alkali can cause problems for your body's balance. For example, eating too many grapes or tomatoes will make your blood more acidic than normal.
