Alkaline foods include tofu, peas, protein, milk, celery, potatoes, bamboo shoots, mushrooms, carrots, kelp, mung beans, oranges, bananas, watermelons, persimmons and strawberries.

Weak alkaline foods include: tofu, peas, soybeans, mung beans, rape, celery, sweet potato, lotus root, onion, eggplant, pumpkin, cucumber, mushroom, radish, milk and so on. Alkaline foods include spinach, cabbage, cabbage, lettuce, carrots, bamboo shoots, potatoes, kelp, oranges, watermelons, grapes, bananas, strawberries, millet, persimmons, coffee and wine.

Eat more alkaline food. It is found that eating more alkaline food can keep the blood weakly alkaline, reduce the acidic substances such as lactic acid and urea in the blood, and prevent them from depositing on the tube wall, thus softening blood vessels. Therefore, some people call alkaline food "a cleaner for blood and blood vessels". The pH mentioned here is not the nature of the food itself, but the nature of the elements left in the body after digestion and absorption. Common acidic elements are nitrogen, carbon and sulfur. Common alkaline elements are potassium, sodium, calcium, magnesium and so on. Some foods taste sour, such as tomatoes and oranges, but they are all strongly alkaline foods, because the last element after their metabolism in the body is potassium.

Strongly alkaline foods: milk, tea, persimmons, cucumbers, carrots, radishes, spinach, oranges, grapes, taro, kelp, figs, raisins, etc.

Weak alkaline food: potatoes, cabbage, bamboo shoots, mushrooms, rape, pumpkin, tofu, apples, pears, bananas, cherries, etc.

The so-called acidity and alkalinity of food refers to whether the inorganic salts in food are acidic or alkaline. General metal elements such as sodium, calcium, magnesium, etc. They are all alkaline in the human body, and foods containing more of these elements are alkaline foods, such as soybeans, tofu, spinach, lettuce, radish, potatoes, lotus roots, onions, kelp, watermelons, bananas, pears, apples and milk. Some foods contain more nonmetallic elements, such as phosphorus, sulfur and chlorine. After oxidation in human body, acidic free radicals with anions are generated, 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.

The food we eat every day can be roughly divided into acidic food and alkaline food. From the point of view of nutrition, the reasonable combination of acidic food and alkaline food is the guarantee of good health.

Food acid-base table

Strongly acidic food: egg yolk, cheese, dessert, sugar, tuna, flounder.

Acidic food: ham, bacon, chicken, pork, eel, beef, bread and wheat.

Weakly acidic food: white rice, peanuts, beer, laver, octopus, chocolate, hollow powder, onion.

Strongly alkaline foods: grapes, tea, wine, kelp, oranges, persimmons, cucumbers and carrots.

Moderately alkaline foods: soybeans, tomatoes, bananas, strawberries, protein, prunes, lemons, spinach, etc.

Weak alkaline food: red beans, apples, Chinese cabbage, tofu, cabbage, rape, pears, potatoes.

Most people have a vague understanding of the acidity and alkalinity of food, and think that lemon that tastes sour is acidic. In fact, the acidity and alkalinity of food is not simply judged by taste. The so-called acidity and alkalinity of food refers to whether the inorganic salts in food are acidic or alkaline. The acidity and alkalinity of food depends on the type and content ratio of minerals contained in food: potassium, sodium, calcium, magnesium and iron react in an alkaline way after entering the human body; Phosphorus, chlorine and sulfur are acidic after entering the human body. Alkaline foods are mainly divided into: 1. Vegetables and fruits; Second, seaweed; Third, nuts; 4. Cereals and beans that have sprouted. Avoid or reduce the intake of the following acidic foods: 1. Starch; Second, animal food; Third, sweets; 4. Refined processed food (such as white bread); 5. Fried food or cream; Six, beans (such as peanuts, etc.). )

Alkaline food recommendation

1. Apple. Fruit is the most digestible food and the best cleanser in the body. Among fruits, apples are called the best alkaline food, which can improve the acidic constitution to maintain the acid-base balance of the human body. Eating apples can quickly neutralize excessive acidic substances in the body, thus enhancing physical strength and disease resistance. In addition to neutralizing the acid-base balance, research and analysis also show that eating apples often is beneficial to lose weight, because apples will increase satiety, and eating before meals can reduce food intake and achieve the purpose of losing weight.

2. Vegetables: Almost all vegetables, especially green leafy vegetables, are alkaline foods. They are rich in vitamins and minerals and can supplement the body with nutrition. A large amount of cellulose in vegetables can also improve the digestive function of the human body and maintain the health of the stomach. Therefore, it is very suitable to use them to neutralize a large number of acidic foods in the body, such as meat and starch, to help food digest and excrete in time.
