1. The so-called acidity and alkalinity of food refers to whether inorganic salts in food are acidic or alkaline. General metal elements such as sodium, calcium, magnesium, etc. It is alkaline in human body, and foods containing more of these elements are alkaline foods, such as soybean, tofu, spinach, lettuce, radish, potato, lotus root, onion, kelp, watermelon, banana, pear, apple and milk. Some foods contain more nonmetallic elements, such as phosphorus, sulfur and chlorine. Acidic free radicals with anions are generated after oxidation in human body, which belongs to acidic food. Such as pork, beef, chicken, duck, eggs, carp, oysters and shrimp, as well as flour, rice, peanuts, barley and beer.
2. If there are more sodium ions, potassium ions, magnesium ions and calcium ions produced after food metabolism, it is easy to produce more alkali in the body and form an alkaline reaction. Generally speaking, foods containing more minerals such as potassium, calcium and magnesium belong to alkaline foods.
Second, alkaline food.
1. Weak alkaline foods: red beans, radishes, apples, cabbages, onions, tofu, etc.
2. Moderately alkaline food: dried radish, soybean, carrot, tomato, banana, orange, pumpkin, strawberry, protein, dried plum, lemon, spinach, etc.

9. Weak alkaline food: potatoes, cabbage, reed, bamboo shoots, pea pods, pumpkin, lotus root, radish stains, tofu, apples, pears, bananas, pineapples, cherries, peaches and beef.
10, strong alkaline foods such as milk, tomatoes, cucumbers, radishes, carrots, figs, spinach, celery, oranges, grapes, taro, kelp, raisins and glutinous rice.
1 1, weakly alkaline foods: red beans, radishes, apples, Chinese cabbage, onions, tofu, etc.
12. Moderately alkaline foods: dried radish, soybeans, carrots, tomatoes, bananas, oranges, pumpkins, strawberries, protein, dried prunes, lemons, spinach, etc.
13. Strongly alkaline foods: grapes, tea, wine, kelp buds, kelp, etc. In particular, natural green algae is rich in chlorophyll, which is a good alkaline health care product, while tea should not be overdone, and the best drinking time is in the morning.

5. Acidic food: ham, bacon, chicken, tuna, pork, eel, beef, bread, wheat, cream, horse meat, etc.
6. Weakly acidic foods: white rice, peanuts, beer, wine, fried tofu, seaweed, clams, octopus and loach.
Fourth, comprehensive classification.
Acidic food: animal food other than milk, such as grain, candy, cakes, fish, pork and other animal meat;
Alkaline food: plant food other than whole grains, such as fruits, vegetables and bean products; Among animal foods, only milk and animal blood are alkaline foods, and others are acidic foods;
Neutral food: oil, salt, coffee, tea, etc.
