Meat is acidic. Vegetables are alkaline.
Acidic food and alkaline food
In nutrition, foods are generally divided into two categories: acidic foods and alkaline foods. The acidity and alkalinity of food has nothing to do with the PH value of the food itself (sour food is not necessarily acidic food), which is mainly defined by the fact that food is digested, absorbed and metabolized in the human body and eventually becomes acidic or alkaline. Those that produce acidic substances are called acidic foods, such as animal viscera, muscles and plant seeds (grains). Alkaline substances are called alkaline foods, such as vegetables, melons, beans and tea.
Animal viscera, muscle, fat, protein and grain are rich in sulfur (S), phosphorus (P) and chlorine (Cl), which are metabolized in human body to produce sulfuric acid, hydrochloric acid, phosphoric acid and lactic acid, which are the sources of acidic substances in human body. However, most vegetables, fruits, kelp, beans and dairy products contain many elements such as calcium (Ca), potassium (K), sodium (Na) and magnesium (Mg), which can become alkaline substances after metabolism in the body.
Alkaline food reacts with carbon dioxide after entering the human body to generate carbonate, which is excreted with urine, while acidic food generates ammonium salt in the kidney and is excreted, thus maintaining the normal PH value of blood. The blood pH of normal people is 7.35, which is weakly alkaline. The PH range is 1 ~ 14, and the PH value of water is 7 (neutral). Below 7 is acidic, and above 7 is alkaline.
If you eat too much acidic food and can't neutralize it, it will lead to acidity and consume basic elements such as calcium, potassium, magnesium and sodium, which will lead to blood color deepening, viscosity increasing and blood pressure rising, thus causing acidosis. Young people can induce skin diseases, neurasthenia, hyperacidity, constipation and tooth decay, while middle-aged and elderly people are prone to hypertension, arteriosclerosis, cerebral hemorrhage and gastric ulcer. Acidosis is because you eat too much acidic food and can't be partial to food. You should eat more vegetables and fruits to keep the acid-base balance in your body.
Although fruit contains all kinds of organic acids, it tastes very sour, but most of it is oxidized into alkaline food after digestion. However, strawberry has organic acids (benzoic acid and oxalic acid) that cannot be oxidized and metabolized, which will increase the acidity of body fluids. They are all acidic foods, with one exception. The main organic acids in vegetables are malic acid, citric acid, tartaric acid and oxalic acid. Here we should pay special attention to oxalic acid, its organism is not easy to oxidize, and calcium oxalate formed with calcium salt is insoluble in water and accumulates in the kidney, which affects the absorption of calcium. Among vegetables, tomatoes, potatoes and spinach all contain oxalic acid. In theory, alkalosis can also occur, but alkalosis is not common in humans, because humans have a lot of stomach acid to neutralize.
Kelp, fruit and beans are the best alkaline foods.
We know that under normal circumstances, human blood is alkaline; If the brain is overused or the physical strength is overdrawn, the blood is acidic; If you eat acidic food for a long time, it will also make your blood acidic. Long-term acidity of blood will degrade brain and nerve functions, leading to memory loss. The method of nourishing is to eat alkaline food often and eat less acidic food.
Generally speaking, foods containing phosphorus, chlorine and sulfur are acidic foods, such as rice, flour, fish, meat, duck eggs, peanuts, sugar and beer. If you eat too much, your blood will acidify. Conversely, foods containing sodium, calcium and magnesium are alkaline foods, such as vegetables, fruits, beans, kelp, milk and tea.
Among them, kelp has the highest alkalinity, followed by fruits and beans. As for the popular natural food and natural food, it is certainly appropriate, but it is not necessary to insist on eating natural food to avoid going too far.
Alkaline food: plant food other than whole grains, such as fruits, vegetables and bean products; Among animal foods, only milk and animal blood are alkaline foods, and others are acidic foods.
Question 2: Will eating alkaline food often help you lose weight? Food is also divided into acid-base neutralization, and different foods have different effects, but for slim and beautiful women, which food is more conducive to weight loss? Many people say that eating alkaline food often helps to lose weight. Is losing weight really good for you? Acidic food: The acidity and alkalinity of food is determined by the products of food digestion, absorption and metabolism. Generally speaking, foods containing more nonmetallic elements such as fluorine, chlorine, sulfur and phosphorus are called acidic foods. For example: meat and poultry, eggs, fish, grain, oil, peanuts, sugar, beer and so on. These foods are high in sulfur and phosphorus, which are metabolized into sulfuric acid and phosphoric acid in human body, increasing the acidity of body fluids. Alkaline food: Foods containing more metal elements such as potassium, sodium, calcium and magnesium are called alkaline foods. For example: vegetables (wax gourd, tomato, pumpkin, cucumber, radish, spinach, Chinese cabbage, cabbage, rape, celery, lotus root, onion, eggplant and potato), fruits (apples, pears, bananas, peaches, strawberries, plums, persimmons, grapes, oranges, grapefruit and lemons), beans and bean products. The mineral content is much higher than that of vegetables and fruits, and sweet potato belongs to strong alkaline food. Organic acids in these foods participate in metabolism in the body. After oxidation in the body, oxygen, carbon dioxide and water will be produced and excreted, and the residual metal ions can increase the alkalinity of body fluids. Neutral food: the metal elements and nonmetal elements contained in food are basically balanced, and the acidity and alkalinity of metabolites are basically balanced after entering the human body, which is called neutral food. For example: milk, asparagus, etc.
Question 3: Is acidic food good for losing weight? I think alkaline food is good for people.
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

Question 4: Can you lose weight by eating only alkaline food? Modern health science believes that we should eat more alkaline food and less acidic food to directly correct the acidic environment. The so-called alkaline food refers to foods containing sodium, calcium, magnesium and potassium, such as vegetables (wax gourd, tomato, cucumber, radish, eggplant, spinach and potato), fruits (apples, pears, bananas, peaches, strawberries, plums, persimmons and grapes), beans and bean products, kelp, milk, fungi and tea. On the contrary, holiday foods such as fish, meat, poultry, eggs and oil are all acidic foods. So these foods should not be eaten more. Ancient people's health care is different from "sour taste" and "sweet taste", while modern people's health care is different from "acidic" and "alkaline", and the difference is a thousand miles. Sour taste and sour taste are different concepts. "Sour taste" is from the perspective of taste, while "acidity" is from the perspective of chemical composition. The former is feeling and taste, while the latter is rationality and analysis, each with its own advantages and disadvantages. Vinegar, which is inevitably thought of as sour taste, is a good example of this. In taste, it is acidic, but in composition, it is alkaline. However, it must be the faint or thick sour taste that affects our taste buds and causes infinite reverie. "Sour" has various forms-the crowning touch is ambiguous as far as the popularity of sour taste is concerned, whether it is a taste or a state of life. People who like acid love it very much, but they can't love it more; Sour people are eager to avoid it, but they cannot avoid it too far. Acid is very complex and difficult to interpret psychologically and emotionally. Even from the pure taste, acid is a kind of taste that is difficult to generalize and characterize. In contrast, sweetness and saltiness are unlikely to be blurred. Sour taste is different from salty taste and sweet taste, and can form a delicious food alone. Sour taste is not suitable for walking alone. High purity sour taste is hard to accept. The special psychological function of sour taste in quenching thirst of plums has nothing to do with taste. The biggest feature of sour taste is that it can be combined with various flavors and changes endlessly.
Question 5: Can you lose weight by eating more alkaline food? It is best to lose weight in a healthy environment. The human body needs an environment with suitable acid and alkali, but the modern human body system is generally acidic, so it is necessary to supplement the alkaline diet appropriately.
Question 6: Can you lose weight by eating more alkaline food? Forty points. . The things upstairs are very interesting. Fruits and vegetables are alkaline foods. . Even vinegar is an alkaline food. . .
Eating more alkaline food is good for your health and good for losing weight, but you can't lose weight by this.
You can't just eat alkaline food. .
If you want to lose weight, you should exercise more.
Question 7: Is the human body alkaline? Fast acidic constitution is easy to cause cancer, and weak alkaline constitution is the constitution with the best organ function.
Question 8: Can alkaline food be eaten for a long time? Eat more alkaline food. It is found that eating more alkaline foods can keep the blood weakly alkaline and make the blood acidic, such as lactic acid and urea.
The quality is reduced, and it can prevent it from depositing on the tube wall, so it has the effect of softening blood vessels, so some people call alkaline food "the cleaning of blood and blood vessels".
Agent ". 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.
Oranges are strongly alkaline foods, because the last element after their metabolism in the body is potassium.
What is acidic or alkaline food? The so-called acidic food or alkaline food does not refer to the food with sour or salty taste, but refers to the digested food.
Foods in which cations or anions generated after absorption and metabolism are dominant. That is to say, certain foods, such as potassium, sodium,
Calcium and magnesium are the main cations in alkaline food; However, foods that produce anions such as phosphorus, chlorine and sulfur after metabolism are acidic foods.
Lemon, citrus and carambola taste sour, but after metabolism, organic acids become water and carbon dioxide, and the latter is exhaled from the body through the lungs, leaving the rest.
Cations are dominant and still belong to alkaline food; Similarly, although meat, fish, eggs and rice noodles are not sour, they produce more negative ions after metabolism.
It is still an acidic food. Therefore, it is impossible to distinguish acidic food from alkaline food in taste.
The pH of human body is relatively constant.
The pH value in our body is quite constant, because there are some buffering substances in our blood, such as carbonate, phosphate and protein.
Buffer system can prevent the sharp change of pH value, which can be adjusted by lung and kidney, making it less susceptible to food, such as sugar and fat we eat.
Fat and protein are catabolized to produce water and carbon dioxide. It can be said that the latter produces carbonic acid and may increase the acidity of blood, but blood
The buffer system can weaken the acidity, exhale the generated carbon dioxide through the lungs, and keep the pH value of blood constant. Another example is that we eat.
Meat, fish, eggs and other foods produce more negative ions, which we call acid-producing food, but after buffering in the blood, it makes
Salt is produced, and these excess salts are excreted through the kidneys, so that the blood still maintains its original pH value. Similarly, eat alkaline food.
At the same time, through the buffering effect of blood and the regulation of lung and kidney, the pH value of blood is kept constant. Therefore, I want to change my diet to affect the pH in my body.
I'm afraid it's unrealistic to underestimate the regulating function of the body.
Excessive changes in pH value are harmful to health. In some cases, it can lead to changes in blood pH, such as rapid weight loss and diabetes.
Too many acidic substances; Or severe diarrhea, which exceeds the compensatory function of the body; Or dysfunction of pulmonary and renal regulation.
If the pH value of blood drops from normal 7.40 to below 7.30, it will cause fatigue, dizziness, shortness of breath and even nausea and vomiting.
Symptoms such as acidosis. However, this happens when the blood pH rises above 7.50 due to severe vomiting, excessive gastric acid loss or ingestion of certain drugs.
Symptoms of alkalosis such as hand and foot convulsions, numbness and dizziness. At this time, it is harmful to the body and needs to go to the hospital for treatment.
Question 9: Is acidic constitution easy to lose weight or alkaline constitution easy to lose weight? Answer the questions and test the acid-base field
1. Do you often lose your appetite?
2. Do you often sleep badly at night?
Do you often get up in the morning in poor spirits?
4. Do you feel tired every day?
Can't you concentrate on your work for a long time?
6. Are you often emotionally unstable and easily angry?
7. Are your hands and feet always cold and your limbs numb?
8. Often neurasthenia, memory loss?
9. Do you have low immunity and get sick easily?
10. Does your gum bleed easily and the wound fester easily?
1 1. Do you often have headache, leg pain, shoulder pain and back pain?
12. Do you often get skin diseases?
Analysis of test results:
If you answered "Yes" to more than five of the above 12 questions, then you are probably acidic. In addition to self-testing according to the characteristics of acidic constitution listed above, you can also go to the pharmacy to buy PH precision test paper to test yourself. The PH value of human urine is generally 5.5 ~ 6. It is recommended to check urine with test paper in the morning. If the PH value is lower than 5 for many times, it also means that you may belong to acidic constitution. If necessary, you can go to the hospital for further examination and confirmation, so that you can prescribe the right medicine.
Prevention and improvement of acidic constitution
The acid constitution is caused by the lack of alkaline substances in the body. Self-prevention and improvement of acidic constitution can start with diet. First of all, adjust the diet structure and keep the balance of nutrient intake. You can eat more alkaline foods, such as fruits, vegetables, soda cookies and so on. Drink more alkaline ionized water and less acidic water, such as purified water and cola. Secondly, we should ensure proper exercise and put an end to bad habits such as smoking and drinking. Finally, emotions have a great influence on the acidification of body fluids, so it is also important to maintain a good mood.
