Why do old people say that they eat more tomatoes, acidic vegetables and fruits such as citric acid

Eat more acidic vegetables and fruits such as tomatoes and citric acid for breakfast, which is conducive to nourishing the liver. However, acidic vegetables and fruits such as tomatoes and citric acid must be eaten after breakfast, and eating them on an empty stomach is not good for the stomach.

Tomato, i.e. tomato (scientific name: lycopersicon esculentum mill.).It is an annual or perennial herbaceous plant of the tubular, Solanaceae, and tomato genus, with a body height of rice, all raw sticky glandular hairs, with a strong odor, the stem is easy to lodging, the leaves are pinnately compound or pinnate deeply lobed, the total peduncle of the inflorescence is 2-5 cm long, often 3-7 flowers, the calyx is spoken, the corolla is radial, the berries are oblate or nearly globular, fleshy and juicy, the seeds are yellow, and the flowering and fruiting period is summer and autumn.

Red tomatoes, fiery red fruit color, generally slightly oblate spherical, small umbilicus, thick meat, sweet taste, juicy and refreshing, good flavor, raw food, cooked food, can also be processed into tomato sauce, tomato juice; Pink tomato, fruit pink, nearly spherical, small umbilicus, smooth fruit surface, moderate sweet and sour taste, good quality, yellow tomato, orange yellow fruit large, round spherical, thick flesh, flesh and flour and sand, raw food taste is light, should be cooked.

Lemon (scientific name: Citrus limon (L.).) burm.

f.), is a citrus plant of the dicot class Rutaceae, lemon is also known as lemon fruit, lemon, mother fruit, etc. Small tree with few thorns or nearly no thorns, young leaves and flower buds dark purplish-red, thick papery leaves, ovate or oval.

Single-flowered axillary or few clusters of flowers. The fruit is oval or ovate, the pericarp is thick, usually coarse, lemon-yellow, the juice is acidic to very acidic, the seeds are small, ovate, and the tips are pointed; The seed coat is smooth, the cotyledons are milky white, and usually single or both. The flowering period is from April to May, and the fruiting period is from September to November.

Because of its extremely sour taste, lemon is the most popular food for pregnant women, so it is called Yimu fruit or Yimu and child. Lemons are rich in citric acid, so they are known as the "citric acid storehouse". Its fruit is juicy and crisp, with a strong aromatic aroma.

Because of its sour taste, it can only be used as a high-quality seasoning for beverages, dishes, cosmetics and medicines. In addition, lemon is rich in vitamin C, which can dissolve phlegm and relieve cough, and strengthen the stomach. It is used for symptoms such as bronchitis, whooping cough, loss of appetite, vitamin deficiency, heat stroke, polydipsia, etc"Scurvy"The nemesis.

Because the tomatoes in the breakfast, the citric acid also has the halmon ingredient, because the human stomach and intestines pass through a night of friction. It is necessary to absorb a large amount of fruit components to pay attention to the effect of excretion and cleansing the intestines.

Because people think that eating these things in the morning can be good for the body.

Because it will play a good role in the maintenance of the human body.

This is a summary of some experiences in daily life.

Because it can synthesize the body's acid-base balance.

In this way, it is easy to expel the stool from the body.

Because it's a habitual perception of people.

Because this is good for the body.

That's because eating more of these for breakfast allows you to fully absorb the nutrients.

I haven't heard of it, but it's always good to eat more fruits.

Eat more acidic vegetables and fruits such as tomatoes and citric acid for breakfast, which is beneficial to nourish the liver and empty the air. In the daily diet, you can eat some sour food, such as hawthorn, oranges, grapes, etc., when eating or making certain dishes, you need to add some vinegar appropriately with your friends can also play a proper role in nourishing the liver.

Lemons, pineapples, oranges, and loquat are all fruits that contain more citric acid.

Tomatoes, lemons, sweet oranges, etc.

This question begins with understanding the definitions of acidic and alkaline foods. Acidic or alkaline food is a physiological concept, not a simple taste or chemical concept. It refers to whether a person eats a certain food, digests and absorbs it, metabolizes it, and finally becomes acidic or alkaline in the body.

Some foods (such as tomatoes) are a strong alkaline food despite being very acidic, because it ends up producing alkaline substances in the human body instead of the acidic taste sensation; However, people do not feel any difference between acid and alkali when eating eggs, and if they are chemically determined, they are alkaline, but they are acidic in the body. Of course, there are also foods whose taste, chemical determination, physiological and metabolic results, and pH are consistent.

It can be seen that the judgment and selection of acidic and alkaline foods should not be based on people's ordinary impressions, but should be understood from the perspective of nutrition. Acidic foods commonly eaten include: whole grains, meat, poultry, aquatic products, eggs, peanuts, walnuts, etc.; Commonly consumed alkaline foods are:

Vegetables, roots and stems in grains (such as sweet potatoes, potatoes), fruits, milk, chestnuts, almonds, etc.

Further, the reason why the above-mentioned foods are acidic or alkaline is related to the fact that they contain certain elements, such as chlorine, sulfur and phosphorus are acid-forming elements; Potassium, calcium, sodium, and magnesium are alkali-forming elements. The amount of these elements in a food determines its acidity and alkalinity. There are also some foods, such as oil, sugar, and starch, which basically do not contain these elements, and do not produce acidic or alkaline substances after metabolism, which can be considered neutral foods.

The metabolism of food is complex, a healthy person has a strong adaptability to food, can self-regulate, often neutralize the acid or alkali produced after metabolism and excrete it in time, so that the body is always in a relatively stable and balanced state. What's more, our food is basically a "balanced diet" or a mixed diet, and generally speaking, there is no need to worry about the acidity and alkalinity of food.

In the case of citric acid, it is an acidic substance because of its chemical properties.

Lemons are alkaline foods.

In addition, even if honey is added, it is still alkaline.

Lemons are very sour, and most people mistake lemons for acidic foods, but in fact, sugar-free lemon juice and lemonade are alkaline foods that are very helpful for the body to absorb.

From a chemical or food science point of view, there can be a big difference between whether a food is acidic or alkaline. Are lemons acidic or alkaline? Most people will think that people who have a sour taste are acidic. But from a food science point of view, lemons are alkaline foods.

So what are alkaline foods? What are acidic foods?

Alkaline food: After the food is digested and metabolized, it is alkaline food.

Alkaline foods contain more metallic elements, such as calcium, potassium, sodium, iron, magnesium, zinc, etc. After being absorbed and metabolized by the body, it produces alkaline oxides with cations, which can buffer acidic metabolites.

Alkaline foods include vegetables, seafood (kelp, seaweed, cauliflower, wakame), fruits, tea, coffee, etc. Milk and yogurt are also alkaline foods, as are oranges, hawthorns, tomatoes, and apricots with a sour taste. Because the organic acids (arboric acid, ascorbic acid, oxalic acid and other acids) are completely metabolized into carbon dioxide, water and energy in the body.

Acidic food: It is not a food with a sour taste, but a food with acid roots that is formed after being digested and metabolized by the human body.

This kind of food generally contains more fat and sugar, such as candy and starchy food (such as rice, white flour), etc.

Excessive consumption of acidic food leads to acid-base imbalance in the human body, which will cause acidic constitution disease, and its main symptoms are dizziness, tinnitus, general weakness, cold hands and feet, susceptibility to sensation, dryness and roughness, and wounds that are difficult to heal.

When lemon juice enters the human body, it will oxidize and burn into carbon dioxide and water, and the rest will become inorganic. We can look at its inorganic substances to determine whether it is alkaline or acidic.

So, from a food science point of view, lemons are alkaline foods that are good for the body when consumed regularly.

In addition, it is still alkaline after adding honey.

After lemon is digested and metabolized by the human body, the substance left in the human body is mainly sodium bicarbonate, and the sodium bicarbonate solution is alkaline, so lemon is actually an alkaline food. The reason why lemons are sour is because lemons contain a lot of organic acids such as citric acid, which leads to a sour taste, but after entering the human body, citric acid will be decomposed into carbon dioxide and water after oxidation and will be excreted from the body, while salts such as sodium citrate will remain because sodium ions cannot be decomposed, and eventually appear alkaline.

Nutritionally, foods are divided into acidic foods and alkaline foods, which are not only distinguished by the pH value of the food itself, but also determined by whether the metabolites of the food in the human body are acidic or alkaline. Alkaline food refers to food that contains more calcium, iron, potassium, manganese, zinc, sodium and other metal elements, and the substances that are metabolized in the human body are alkaline.

Although there is citric acid in lemons, citric acid can be completely metabolized in the body to produce carbon dioxide and water, and as carbon dioxide is exhaled out of the body, the acidity is also eliminated.

Lemons contain citric acid, so they taste sour.

Lemons are rich in citric acid, so they taste sour.

This is because its fibers give the impression that its taste is sour.

Because it contains citric acid.

Being too alkaline can also cause the taste to become sour.

It's just that people's sense of taste is different.

I think it's the taste of the people.

Maybe it contains acidic substances.

There is no rule on what alkaline food tastes like.

Because vegetables and fruits contain potassium, sodium, calcium, magnesium and other salts, they are metabolized in the human body to produce alkaline substances, making body fluids weakly alkaline. This type of food is physiologically called alkaline food.

2. The citric acid and its potassium salt in lemon are thoroughly oxidized in the body, and the citric acid is finally excreted into carbon dioxide and water, leaving alkaline potassium salt. Therefore, this type of acidic food is alkaline food. Although she tastes sour, which is felt by our own sense of taste, but chemically it is alkaline, can you understand this?
