There are acidic foods, what are acidic foods?

The classification of acidic and alkaline foods is determined by the acidity and alkalinity of the inorganic salts that remain in the body after digestion, rather than the pH value of the food directly tested. 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, broad beans, beer, flour, peanuts, fried tofu and dried seaweed.

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.

Acidic foods refer to the properties of food.

Acidic food does not refer to food that feels sour in the mouth, it has nothing to do with human taste sensation, but only depends on human metabolite properties. After human beings eat, the body produces metabolites, and if the property of the metabolite is alkaline, then the property of the food is acidic.

Acidic foods are very common in life, such as chicken, duck and fish. In general, acidic foods can be simply divided into six main categories:

1.animal foods, such as pork, etc.;

2.Legume; 3.starches;

4.creamy and fried foods;

5.sweets;

6.Refined processed foods.

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.

Alkaline food refers to the chemical composition of the ash obtained by the combustion of food, which mainly contains potassium, sodium, calcium, magnesium and other elements, which are dissolved in water to form alkaline solution, such foods include various vegetables, fruits, beans, milk and almonds, chestnuts and so on in hard fruits.

For the distinction between acid-base foods, everyone may have the wrong idea, thinking that it is tasted by the tongue and judged by taste to be sour or astringent; Or take litmus test paper, according to the physical and chemical characteristics, to see the change of its color, turn blue to alkaline, red to acidic; Or distinguish by your own experience. There are many different kinds of sayings. From the perspective of nutrition, acidic food and alkaline food actually refer to the ash obtained by the food after combustion, and the acidity and alkalinity of the aqueous solution after dissolving in water are determined, acidic food and alkaline food is a non-physiological concept, and the food ash that determines the acidity and alkalinity of food refers to the oxides of some elements left after food is burned, which is completely different from the nature of metabolites after food is digested, absorbed and utilized in the body.

In fact, it is unscientific to divide food into acidity and alkalinity, because the physiological response in the human body is very complex, and it is not necessarily alkaline or acidic, as long as the diet is balanced and reasonable. Most people think that sour things are acidic foods, strawberries, lemons, etc., which will make their mouths water, but in fact, these things are typical alkaline foods. And vice versa.

Almost all delicious foods are acidic, such as fish, meat, rice, sake, sugar, etc., all of which are acidic foods.

1. Alkaline food.

Alkaline foods that contain more metal elements such as sodium, potassium, calcium, and magnesium are alkaline foods. It is not a sour food that tastes sour, and it should be understood that all sour fruits and soy products are alkaline foods rather than acidic foods, and alkaline foods are considered to have a beauty effect.

Tofu, milk, celery, potatoes, bamboo shoots, shiitake mushrooms, carrots, kelp, mung beans, bananas, watermelons, strawberries, and most vegetables and fruits are alkaline.

The "acidity and alkalinity" of food can affect posture and bodybuilding.

After determination, 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.

Eat more alkaline foods. Studies have found that eating more alkaline foods can keep the blood weakly alkaline, reduce the acidic substances such as lactic acid and urea in the blood, and prevent them from being deposited on the tube wall, so it has the effect of softening blood vessels, so some people call alkaline food "the cleanser of blood and blood vessels". The acidity and alkalinity mentioned here is not the nature of the food itself, but the nature of the elements that remain in the body after digestion and absorption.

Common acidic elements are nitrogen, carbon, sulfur, etc.; Common basic elements are potassium, sodium, calcium, magnesium, etc. Some foods taste very sour, such as tomatoes and oranges, but they are all authentic strong alkaline foods, because the final element after their metabolism in the body is potassium and so on.

2. Acidic food.

Acidic food refers to the inorganic salts that can form acids in the human body, such as phosphorus, sulfur, chlorine and other elements, which can make body fluids appear acidic, and the common foods are protein-rich meat, fish, poultry, eggs, cereals, peanuts, hazelnuts, walnuts, etc. Specifically: pork, beef, chicken, egg yolk, carp, eel, dried squid, shrimp, rice, flour, bread, barley, beer, asparagus, etc.

Although you lack acidic foods in your body, you should not blindly supplement them, because medical proof shows that when we eat a large amount of acidic foods containing chlorine, sulfur, phosphorus and other acidic foods, it is extremely difficult for the blood to maintain a weakly alkaline state, and acidosis is prone to occur.

Acidic foods are mainly meat foods, and alkaline foods are mostly vegetables and fruits, if too much acidic food is consumed, it is easy to cause obesity, indigestion, etc., so it is necessary to consume alkaline foods to maintain the acid-base balance in the body. Eating more alkaline foods to promote a slim body is good for **, promotes digestion, and can also improve IQ, so you should usually eat more alkaline foods and combine them with acidic foods to promote good health.

Summary. Hello dear, acidic food refers to food that is left in the body after digestion and eventually forms acid forms such as nitrogen, carbon, sulfur, chlorine, and salt. They are usually rich in protein, fat and sugar, and because they contain more sulfur (S), phosphorus (P), chlorine (Cl) and other elements, they will produce substances such as sulfuric acid, hydrochloric acid, phosphoric acid and lactic acid after being metabolized in the human body.

Acidic foods in daily life mainly include meat, grains, egg yolks, dried seaweed, etc.

Hello dear, acidic food refers to food that is left in the body after digestion and eventually forms acid forms such as nitrogen, carbon, sulfur, chlorine, and salt. They are usually rich in protein, fat and sugar in celery and a foot of the first acre, because they contain more sulfur (S), phosphorus (P), chlorine (Cl) and other elements, and will produce sulfuric acid, hydrochloric acid, phosphoric acid and lactic acid and other substances after metabolism in the human body. Acidic foods in daily life mainly include meat, grains, egg yolks, dried seaweed, etc.

Kiss! Here is an extension for you: Strongly acidic food:

Egg yolks, yogurt, desserts, sugar, tuna tung fish, flounder. Medium acidic foods: ham, bacon, chicken, pork, eel, beef, bread, wheat.

Weakly acidic foods: white rice, peanuts, beer silver, seaweed, octopus, chocolate, water flour, green onions.

Acidic foods are foods that remain in the body in the form of acid after digestion.

Acidic food refers to the digestion and absorption of the digestive tract, which is converted into inorganic salts, and its metabolites are non-metallic ions, most of which are acidic. 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 the direct pH of the food.

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.

For example, animal liver, meat, fat, protein, and cereal foods contain more anions such as sulfur, phosphorus, and chloride, and are prone to produce acidic substances such as lactic acid and phosphoric acid after metabolism in the human body, so they are acidic foods.

Application of acidic foods

The acidic foods in daily life mainly include beef, sheep, pig, chicken, duck, fish, grains, egg yolks, white rice, shrimp, brown rice, bread, bread, beer, flour, peanuts, fried tofu and dried seaweed. The spring diet should "save acid and increase sweetness", and acidic foods include beef, mutton, dog meat, duck, quail, river mussels, marine fish, shrimp, crabs, etc. You can eat more yams, spring bamboo shoots, spinach, jujubes, leeks, shepherd's cabbage, white fungus, etc.

In addition, fruits should also be eaten warmly.

Protein foods such as meat and eggs need to be digested in strong acid gastric juice, while starchy foods such as bread need to be exerted in an alkaline environment.
