It is recommended to eat foods with more metal elements such as potassium, sodium, calcium and magnesium for acidic physique, which is called "alkaline food". For example: vegetables (white gourd, tomato, pumpkin, cucumber, radish, spinach, Chinese cabbage, cabbage, rape, celery, lotus root, onion, eggplant and potato), fruits (apples, pears, bananas, peaches, strawberries, plums, grapes, oranges, grapefruit and lemons), beans and bean products (beans and bean products)

Organic acids in these foods participate in metabolism in the body. After oxidation in the body, oxygen, carbon dioxide and water will be produced and excreted, and the remaining metal ions can increase the alkalinity of body fluids.
