Maintaining the balance between acid and alkali in the human body depends on the acid and alkali of the food consumed and the adjustment of the acid-base balance by the excretion system. The acid-alkaline reaction of a food is the result of metabolism in the body after digestion and absorption. If the plasma of phosphate, sulfate and chloride ion produced after food metabolism is large, it is easy to form acid in the body. If there are many sodium ions, potassium ions, magnesium ions, and calcium ions, a large amount of alkali may be produced in the body to form an alkaline reaction. This is related to the mineral content in food. Generally, foods with more minerals such as sulfur and phosphorus are acidic foods. foods with more minerals such as potassium, calcium, and magnesium are alkaline foods. Some foods, such as oil, sugar, starch, and so on, basically do not have the above two types of elements, so they are neutral food, these foods do not affect the pH of body fluids. Therefore, it can be seen that the so-called acidic food cannot be understood as sour food, sour fruit such as tomato, orange, Hawthorn, bayberry, etc. after body metabolism. the final impact on human body is alkaline.
So what are common alkaline foods? Such as tofu, peas, soy beans, mung beans, rape, celery, sweet potato, lotus root, onion, eggplant, pumpkin, mushroom, radish, spinach, cabbage, cabbage, lettuce, lettuce, mushrooms, carrots, bamboo shoots, potatoes, konjac, kelp, seaweed, citrus, watermelon, grape, banana, apple, pear, strawberry, Chestnut, persimmon, milk, wine, etc. What are the main acidic foods? Such as rice, flour, animal meat (beef, pork, mutton, chicken, duck, etc.) and eggs.
Generally, the daily staple food required by middle-aged and elderly people is 300 ~ 400 grams. If you eat alkaline root food such as sweet potato and potato, the amount of staple food can be reduced as appropriate. Animal meat is the most important acidic food and should be controlled within loo grams every day. Generally, you need to eat more alkaline foods such as vegetables and fruits to avoid acidic constitution.
