Beware of physical acidification at the turn of summer and autumn Xiao Ming Blood pH The human body is composed of various chemical substances, and each chemical substance has its own chemical properties. The pH of the human body is a chemical property. The acid-base changes of human body are closely related to health. In particular, the acid-base changes of human body fluids are a direct indicator of human health. There are many types of body fluids in the human body, the largest of which is blood. Normal body fluids should be weakly alkaline except for gastric juice. Since blood accounts for the absolute majority of body fluids, and its pH can directly affect the pH of body fluids in various parts of the body through the circulatory system, the pH of blood has become a decisive factor and important indicator of the overall pH of body fluids. In addition, when testing pH, it is much more convenient to draw blood than most other body fluids. Therefore, in medicine, the pH of blood is used to analyze the overall pH of body fluids, that is, the pH of the human body, to study the health of the human body. The importance of blood to the human body and life is well known, and the acid-base degree of blood represents the pH of the human body. Some people may not know its importance to human health, so the following will focus on the knowledge about the changes in blood acid-base. Blood Acidification and Disease If an aqueous solution contains a compound that can give out hydronium ions, it is an acidic solution; if it contains a compound that can give out hydroxyl radicals, it is an alkaline solution. This has been introduced in middle school chemistry textbooks. The acidity and alkalinity of an aqueous solution is expressed by the pH value: when the pH value is equal to 7, it is neutral; when the pH value is greater than 7, it is alkaline; the greater the pH value is than 7, the stronger the alkalinity; when the pH value is less than 7, it is acidic , the smaller it is than 7, the stronger the acidity. The pH value of normal blood in healthy people should be 7.35 to 7.45, which is weakly alkaline. The normal blood pH value of a newborn baby is within this range. However, as his (her) living environment and dietary structure change, the pH value of the blood will change to a certain extent. The pH of our adult blood is not necessarily within this normal range, and its changes are closely related to the health status of the human body. Japanese scientists once conducted a survey on cancer patients and found that the blood of nearly 100 cancer patients who participated in the survey was almost all acidic. Later, the scope of this investigation was expanded to include patients with gout, gastric ulcers, hypertension, hyperlipidemia, certain stubborn skin diseases, children's rickets, dental caries and other diseases. Statistics show that more than 85% of patients have blood pH exceeding normal Range and acidic. Scientists have concluded that acidification of the human body is closely related to various diseases. Since then, many medical experiments have confirmed that blood acidification and diseases are mutually causal, that is, the blood is acidic, that is, the overall body fluids become acidic, which can lead to a variety of diseases. On the contrary, many diseases can also cause the body's blood (body fluids) to become acidic. Therefore, the pH of the blood can be brought to normal by treating diseases, and the acidity of the blood can also be reduced to make the blood appear normal and weakly alkaline, thereby helping to treat or prevent corresponding diseases. Acidic physique and sub-health However, when the blood (body fluid) becomes acidic, it does not necessarily indicate that the human body is suffering from a certain disease. Sometimes it only indicates the acidification of the body's constitution. Physical acidification is a transitional physiological state of human beings, between health and disease, which is called sub-health in medicine. The consequences of acidic blood (body fluid) are weakening of cell functions, slowing down of the body's metabolic activities, and the excretion produced by metabolism cannot be discharged from the body in time, thus increasing the burden on the kidneys, liver and other organs. When the human body is in this sub-healthy state, diseases will take advantage of it, so people with acidified blood (also known as acidic constitution in medicine) are very susceptible to various diseases. A medical survey in my country found that more than 60% of residents living in a certain city have an acidic constitution, which is very abnormal. The blood of healthy people should be slightly alkaline, with a pH value between 7.35 and 7.45. Even if it is greater than 7, but less than 7.35, it is also called acidification. The blood pH value of most of the residents surveyed in this city is around 7, and many people have a pH value lower than 7, which is slightly acidic. This indicates that their body fluids have generally become acidic and they have become acidic. There is such a high proportion of people with acidic constitution in the population. This abnormal phenomenon must have a unique cause of the population, which is usually caused by local customs or living environment. After analysis and research, experts believe that environmental pollution is the fundamental reason for the acidification of the body of most residents in the city. Due to the increasingly serious environmental pollution in the city in the past 20 years, the atmosphere, water sources, crops, livestock, poultry, aquatic products, etc. have all been polluted to varying degrees. Therefore, the water and food that residents ingest for a long time and the air they inhale contain harmful elements. Excessive acidic substances will remain in the body, causing the body to become acidic. Irregular work and rest lead to acidification of the body. Even if there is no environmental pollution, unscientific living habits can still cause acidification of the body. Failure to balance work and rest in life, with regular work and rest, especially failure to ensure adequate sleep time, will lead to acidification of the body's constitution. If you do too much physical labor or sports on one day or for several consecutive days, or indulge in dance halls, karaoke bars and other entertainment venues all night, or stay up all night playing mahjong or surfing the Internet... it can cause physiological activity disorders, and the body's fatigue will It will increase the amount of acidic metabolites such as lactic acid and urea in the body, so these acidic metabolites cannot be excreted from the body in time, causing body fluids to become acidic in the short term. At this time, it is still within the normal physiological category. As long as you pay attention to timely rest, the blood (body fluid) can still restore its original pH.

If you have unscientific and irregular work and rest for a long time, such as reluctantly engaging in over-heavy physical labor, overloaded physical training, or all-night carnivals and gambling for a long time, and continuous lack of sleep, resulting in excessive physical exertion, it will lead to long-term acidification of the blood (body fluids) . As a result, the body's physique becomes acidified due to quantitative changes to qualitative changes. In addition, negative emotions such as anger, irritability, fear, excitement, and tension are "catalysts" that promote acidification of the body. When life is irregular, this mental factor plays a role in making matters worse. Acidity comes from the mouth. Of course, it is impossible for most people to indulge in nightlife and be unable to extricate themselves; nor can they force themselves to engage in over-heavy physical labor or overload sports beyond their capabilities for a long time. Generally speaking, most people whose physiques become acidic are caused by their diet. Unscientific. In short, acid enters through the mouth. Since the reform and opening up, the living standards of our people have been greatly improved. Today we eat rice made from refined white rice and flour, and we often eat chicken, duck, fish, meat and other meaty foods. It is also common to go to restaurants for banquets. Judging from people’s daily diet, their food is becoming more and more “high-end”. As everyone knows, eating "high-end" does not mean eating scientifically and rationally. Chicken, duck, fish, meat, etc. are all acidic foods. Long-term intake of too many acidic foods is the main cause of acidification of the human body. In addition, tobacco and alcohol are typical acidic products. Excessive smoking and drinking are also important factors in the acidification of the body. Especially at banquets, most people eat fish, meat and other acidic foods, plus smoking and drinking, which intensifies the acidification process in the body and accumulates acidic substances in the body. People who often go to banquets can easily develop an acidic constitution. How to identify the acidity and alkalinity of food. Since most people's body acidification comes from the mouth, then to prevent body acidification, we must recognize the acidity and alkalinity of food. Let us achieve an acid-base balance in our diet, or eat more alkaline foods. Eat less acidic foods to change your acidic physique. The so-called acidity and alkalinity of food is not judged by the taste organs, nor by the chemical properties of the food after it dissolves in water. It is determined by whether the final substances formed after the food is absorbed by the human body have an acidic or alkaline effect on the body fluids. Determined by function. So foods with sour taste are not necessarily acidic foods. For example, many fruits have a sour taste because they contain fruit acids. However, fruit acid is an organic acid. It is just a carbohydrate. After oxidation and decomposition in the body, it can only form water and carbon dioxide. Fruits are often rich in potassium, sodium, calcium, magnesium and other metal elements. They can form alkaline oxides with cations in the body, making blood and other body fluids alkaline. Therefore, sour fruits are alkaline foods. . Another example is that although meat does not have a sour taste, it does contain non-metallic elements such as sulfur and chlorine. After these elements are oxidized and decomposed in the body, they form anionic sulfate and hydrochloride, causing blood and other body fluids to become acidic. Therefore, animal proteins such as meat without sour taste are mostly acidic foods. At the turn of summer and autumn, beware of physical acidification. The hot summer is about to pass. People have been working, working, and studying for several months in hot weather, which consumes a lot of physical strength and energy. Due to the scorching heat and the interference of mosquitoes, many people, especially workers with poor living environment and living conditions, lack sleep for a long time, and their bodies may have a tendency to become acidic. Therefore, it is especially important to prevent the body from becoming sour at the turn of summer and autumn. We should take advantage of the cooler weather in late summer and early autumn to pay attention to our work, rest and diet, get more rest, get enough sleep, and add more alkaline foods to eliminate the tendency of body acidification to ensure the acid-base balance of the blood (body fluids). The human body reaches a healthy physiological state. Especially those patients with gout, gastric ulcer, rickets, skin diseases, high blood pressure, hyperlipidemia, arteriosclerosis, constipation, neuralgia and other diseases, because their diseases are closely related to blood acidification, they should rest more, sleep more, Eat more alkaline foods and pay great attention to preventing acidification of the body. The acidity and alkalinity of common foods. Get plenty of rest and get enough sleep. Everyone knows it, and it goes without saying. Supplementing more alkaline foods means eating more fruits? Of course you have to eat fruit. But alkaline foods are not limited to fruits. Vegetables are also typical alkaline foods. There are also exceptions among fruits. Persimmons are acidic foods. Although they are both alkaline foods, there are big differences in the amount of alkaline substances they contain. How to distinguish their advantages and disadvantages? In order to facilitate readers to choose food correctly and formulate scientific and reasonable family recipes, the following introduces the acidity and alkalinity of some common foods and their pH levels: Common foods with strong alkalinity that are worth recommending include: grapes, tea, kelp, Natural green algae, snails, black fungus, etc. Common foods with moderate alkalinity include: soybeans, carrots, tomatoes, spinach, rape, amaranth, celery, pickled mustard, mustard, dried radish, pumpkin, egg whites, bananas, oranges, Strawberries, lemons, prunes, seaweed, pickled green vegetables, soy milk replacer, etc. Common foods with weak alkalinity include: adzuki beans, radish, cabbage, onions and other vegetables, tofu and other bean products, apples and other fruits ; Common foods with strong acidity include: egg yolks, mullet roe, bonito, cheese, Western-style sweet pastries, sugar, persimmons, etc. Common foods with moderate acidity include: ham, chicken, pork, beef, horse meat, tuna , eel, bread, wheat, butter, etc. Common foods with weak acidity include: rice, peanuts, corn, oiled tofu, seaweed, clams, octopus, loach, etc. In addition, alcohol is generally an acidic food. If you want to drink alcohol, wine should be your first choice because it is an alkaline food. But wine must be consumed in moderation, as excessive alcohol intake can cause acidification of body fluids.

Edible fats and oils are all acidic foods, but the degree of acidity varies depending on the raw materials used to make the cooking oil. Soybean oil is the first choice for cooking oils with weak acidity. Since edible fats and oils are all acidic foods, fried foods are also acidic foods. Milk contains animal protein, which should be an acidic food, but it is also rich in calcium and other minerals, and it should be an alkaline food. The two offset each other, and it should be considered a weak alkaline food. Because milk is rich in nutrients, nutritionists recommend it to everyone.
