The so-called acidity and alkalinity of food means that the inorganic salts in food are acidic or alkaline.
The general metal elements sodium, calcium, magnesium, etc., in the human body, its oxides are alkaline, and foods containing more of this element are alkaline foods, such as soybeans, tofu, spinach, lettuce, radish, potatoes, lotus root, onions, kelp, watermelon, bananas, pears, apples, milk, etc.
Some foods contain more non-metallic elements, such as phosphorus, sulfur, chlorine, etc., which are oxidized in the human body to form acid groups with anions, which are acidic foods. Such as pork, beef, chicken, duck, eggs, carp, oysters, shrimp, as well as flour, rice, peanuts, barley, beer, etc.
Therefore, we must pay attention to the reasonable combination of acid and alkaline foods, otherwise, eating too much acidic food can cause acidic blood. In order to neutralize these acidic substances, it is inevitable to consume a large amount of calcium, magnesium and other alkaline elements in the body, which causes a series of symptoms such as calcium deficiency, such as ** disease, neuropathy, especially during holidays, if there is more meat, it is necessary to pay more attention to matching some fresh vegetables, fruits and other alkaline foods, so as not to cause the body's acid-base balance imbalance.
It has been determined that the weakly alkaline foods are:
Tofu, peas, soybeans, mung beans, rape, celery, sweet potatoes, lotus roots, onions, eggplants, pumpkins, cucumbers, mushrooms, radish, milk, etc.
And alkaline foods are:
Spinach, cabbage, cabbage, lettuce, carrots, bamboo shoots, potatoes, kelp, citrus, watermelon, grapes, bananas, strawberries, millet, persimmons, coffee, wine, etc.
There are also some foods that are sour because they taste, and people mistakenly regard them as acidic foods, such as mountain plants, tomatoes, vinegar, etc., which are actually typical alkaline foods.
As for acidic foods or weakly acidic foods, in addition to all kinds of livestock and poultry meat, common acidic foods include egg yolks, fish roe, peony, white rice, noodles, bread, steamed fish, octopus and so on.
-
Generally speaking, acidic foods are delicious, such as chicken, fish, meat, eggs, sugar, etc.
Alkaline foods are not very tasty, such as vegetables, tea, fruits (except high-sugar fruits), soy products, milk, etc.
-
Acidic foods are delicious, such as chicken, fish, meat, eggs, sugar, etc.
-
Spinach is an alkaline food. The acidity and alkalinity of food are not based on taste, but the result of absorption and metabolism of food in the body after digestion and absorption.
Common alkaline foods are: soybeans, potatoes, bananas, tofu, pears, green beans, onions, apples, spinach, pumpkin, strawberries, lettuce, cucumbers, persimmons, radish, kelp, milk, carrots, watermelon, tea, etc.
-
Spinach is a relatively common vegetable, and by its nature spinach is alkaline. Spinach contains a large amount of oxalic acid, which is metabolized and oxidized into an alkaline substance after ingestion into the human body. This metabolite contains a large amount of calcium and iron ions, which can not only play a role in iron and blood supplementation, but also increase the strength of bones.
-
Spinach and other green leafy vegetables are alkaline foods, but spinach is relatively high in oxalic acid, so it is best to blanch before eating.
-
A relatively common vegetable, alkaline in nature. It contains oxalic acid, which is metabolized and oxidized into alkaline substances after ingestion. These metabolites contain calcium and iron ions, which not only play a role.
-
Acidic foods include beef, mutton, dog meat, duck, quail, river mussels, sea fish, shrimp, crabs, yams, spring bamboo shoots, spinach, jujubes, leeks, camellia, white fungus, etc.
The classification of acidic and alkaline foods is determined by the acidity and alkalinity of the inorganic salts left in the body after digestion, rather than by directly testing the pH value of the food. For example, protein-rich foods are digested and eventually form nitrogen, carbon, sulfur, chlorine, salt, etc., which form acid roots and remain in the body.
Acidic foods in daily life mainly include beef, sheep, pigs, chickens, ducks, fish, grains, egg yolks, white rice, shrimp, brown rice, bread, silkworm chain beans, beer, flour, peanuts, fried tofu and dried seaweed.
Acidic formation
Many delicious foods are acidic foods, such as fish, meat, rice, wine, sugar, etc. On the contrary, alkaline foods such as sour horn, kelp, vegetables, white radish, tofu and other imitation paulownia are mostly imitation foods that are not easy to arouse appetite but are beneficial to the body and limbs.
Most people have a very vague understanding of the acidity and alkalinity of food, and think that what tastes sour is acidic. In fact, the acidity and alkalinity of food are not determined by simple taste. The so-called acidity and alkalinity of food is determined by the acidity and alkalinity of inorganic salts in food.
Human food is basically divided into five categories: protein, fat, carbohydrate (commonly known as sugar), vitamins, and minerals.
-
Acidic foods are based on the popular theory of acidic constitution, rather than referring to the classification of foods that directly test the pH value. That is, after the food is digested, it eventually forms nitrogen, carbon, sulfur, chlorine, salt, etc., and forms acid roots that remain in the body. Such as:
Cattle, sheep, pigs, chickens, ducks, fish, grains, etc.
Acidic food usually refers to food rich in protein, fat and sugar, because it contains more sulfur (S), phosphorus (P) and chlorine (Cl), which are metabolized in the human body to produce sulfuric acid, hydrochloric acid, phosphoric acid and lactic acid.
Strong acidic foods: egg yolks, cheese, desserts, sugar, tuna, flounder.
Medium acidic foods: ham, bacon, chicken, pork, eel, beef, bread, wheat.
Weakly acidic foods: white rice, peanuts, beer, seaweed, octopus, chocolate, water pasta, green onions.
-
Nutritionists believe that fish, meat, poultry, eggs, rice, flour, fats, sugars, etc. are all acidic foods.
From a popular point of view, acidic foods are as follows: 1. starch; 2. Animal food; 3. Sweets; 4. Refined and processed foods (such as white bread, etc.); 5. Fried food or cream; 6. Legumes (such as peanuts, etc.).
A complete list of acidic foods.
Strong acidic foods: egg yolks, cheese, desserts, sugar, tuna, flounder, cheese, pastries, persimmons, mullet roe, bonito, etc.
Medium acidic foods: ham, bacon, chicken, pork, eel, beef, bread, wheat, tuna, beef, bread, wheat, cream, horse meat, etc.
Weakly acidic foods: chocolate, water flour, green onions, white rice, peanuts, beer, fried tofu, seaweed, clams, octopus, loach, etc.
Relatively speaking, the daily diet consumes more acidic foods, which will acidify body fluids, break the normal acid-base balance, and even form an acidic constitution. Acidic constitution can cause health problems.

What are Acidic Foods? What are Alkaline Foods?
-
Foods that are acidic during digestion and absorption in the human body are called acidic foods, and vice versa are called alkaline foods. Generally speaking, meat dishes such as chicken, duck, fish, and grains are acidic, and vegetables and fruits are alkaline.
