1 The so-called acidity and alkalinity of food means whether the inorganic salts in food are acidic or alkaline. General metal elements such as sodium, calcium, magnesium, etc. are 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, chlorine, etc. After oxidation in the human body, acid radicals with anions are generated, which belongs to acidic foods. Such as pork, beef, chicken, duck, eggs, carp, oysters and shrimps, 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 are alkaline foods.
Second, alkaline food
1. Weak alkaline foods: red beans, radishes, apples, cabbage, onions, tofu, etc.
2. Moderately alkaline food: dried radish, soybean, carrot, tomato, banana, orange, pumpkin, strawberry, protein, dried plum, lemon, spinach, etc.
3. Strongly alkaline foods: grapes, tea, wine, kelp buds, kelp, etc. 4. Vegetables and fruits are alkaline foods. 5. Meat is generally acidic. 6. Coarse grains are alkaline, and flour and rice is acidic.
7. Fish is also an alkaline food.
8. Alkaline foods: tofu, milk, celery, potatoes, bamboo shoots, mushrooms, carrots, kelp, mung beans, bananas, watermelons, strawberries, etc.
9. Weakly alkaline food: potato, cabbage, reed Xun, bamboo shoots, pea pods, squash, lotus root, radish stains, tofu, apples, pears, bananas, pineapples, cherries, peaches and cowries.
10, strong alkaline food milk, tomato, cucumber, turnip, carrot, fig spinach, celery, citrus, grape, taro, kelp, raisin, and tender.
1 1, weakly alkaline foods: red beans, radishes, apples, cabbage, onions, tofu, etc.
12, moderately alkaline food: dried radish, soybean, carrot, tomato, banana, orange, pumpkin, strawberry, protein, dried plum, lemon, 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 food, while tea should not be overdone, and the best drinking time is in the morning.
