The importance of water in children's nutrition. Changes in acid-base balance depending on nutrition
Acid-base balance
The term “acid-base balance” refers to the maintenance of constancy (homeostasis) of the concentration of hydrogen ions (H+) in the fluids of organisms. Acidity is usually expressed in terms of the concentration of hydrogen ions and pH.
Most processes in the human body occur when the reaction of the environment is close to neutral: the maintenance of this reaction is provided by a whole system of buffers, i.e., substances that prevent a significant shift in pH. The most powerful buffer system of the body is blood and its main protein - hemoglobin. Breathing is directly related to this system. The third mechanism involved in the regulation of the constancy of the concentration of hydrogen ions in the blood is renal diuresis.
Normally, the pH of the blood ranges from 7.37 to 7.44 with an average value of 7.38-7.40. Fluctuations in pH from these values in one direction or another are associated with pathological metabolic disorders.
The internal environment of the stomach is acidic, the intestines are alkaline. When these environments are interpenetrated, a neutralization reaction occurs, the processes of digestion and absorption are disrupted (for example, when the contents of the duodenum are thrown back into the stomach).
In addition, the acid-base balance in the human body is of general importance in maintaining normal metabolism. There is a preventive nutrition method based on the correct combination of acid-containing and alkaline-containing foods. The division of food into strong and alkaline has been carried out for a long time.
Acidic foods include all animal products, many cereals, dried legumes, cottage cheese, cheese.
Alkaline foods: vegetables, fruits, nuts (except peanuts), greens, milk, yogurt. It is recommended that during the day, one part of acidic food should account for at least two parts of alkaline food. An alkaline internal environment is characteristic of healthy people and ensures healthy life. Reduces the need for proteins, gives strength and longevity.
A shift in the pH of the blood to the acidic side is called acidosis, which is the cause of many diseases, especially joints. One of the first symptoms of acidosis is dark circles under the eyes, pain in the lower back, spine, neck and chest muscles, Animal Toys joint mobility is lost, irritability, osteoporosis and arthritis appear.
The main causes of acidosis: the use of a large amount of refined carbohydrates, incompatibility of food products, animal digested proteins, insufficient amount of fruits and vegetables.
To reduce the concentration of acid in the body, water is retained, which leads to edema. Acid-base balance is usually shifted to the “acid” side free organic acids - citric, malic, acetic. Oxidation is caused by phosphorus, chlorine.
An alkaline environment in the body promotes health, but this does not mean that you need to switch to eating only alkaline foods.
Water is the basis of life.
Water makes up about 60% of the total mass of a person. Among the various excretions from the body, the largest part comes from water.
Water is the medium in which vital processes take place. Transport of nutrients, excretion of metabolic products, temperature regulation.
Water is expressed by the formula H2O.
Natural water deserves special attention, which includes, in addition to oxygen, other necessary organic substances. Moreover, thanks to its unique chemical composition, natural water causes special reactions in the body.
If there is no proven source nearby, and you doubt the good quality of tap water, you need to boil the water, cool it and pour sour berries - sea buckthorn, apple skin and core, etc. After that, when the water has infused a little, it is fashionable to drink.
Simple boiled water is dead, it has no enzymes, and mineral trace elements are modified.
In recent years, many regions of Ukraine have seen a deterioration in the quality of drinking water. Among them are a high degree of fenal pollution, infection with pathogens of parasitic diseases, including intestinal infections (cholera, typhoid fever, viral hepatitis).
Therefore, it is recommended to use filters for water purification that can eliminate harmful heavy metals, chromium compounds, pesticides, aromatic hydrocarbons, nitrates and radon. You can improve water quality by regulating its acidity, hardness, odor, color, degree of transparency, content of iron, manganese, chloride compounds.
If there is no filter for water purification, you can add a little iodine, apple cider vinegar, or honey to one glass of unboiled water.
The body cannot live in an acidic environment.
In areas where the soil is rich in magnesium and people drink water containing magnesium, eat fruits and vegetables that grow on this land, there are very few cancer patients. Magnesium prevents and treats cancer. In addition, magnesium has a good effect on the nervous and muscular, endocrine, vascular and other systems of the body.
The average daily rate of water excretion is about 2500 g. This amount is individual for each person, therefore, for normal metabolism, everyone should take as much liquid as is excreted from the body. Those who do not drink water allow waste to accumulate in cells and vessels, accelerating the onset of various diseases. In order to prevent the development of diseases, it is necessary to drink water, but you need to drink it wisely. It is best to drink water after you get up in the morning. The amount of water for life depends on the constitution of a person. Therefore, those who are prone to heart or liver diseases, it is better not to drink all the water at once, but to take it in small portions. If a person has a large body structure and is busy with active activities and is used to drinking a lot of water (up to 2-3 liters per day), he can drink as much as he wants in the morning.
It is very useful to drink water immediately after a hot bath or sauna, as this helps to free the body from waste.
A. Zalmanov in his book “The Miracle of Life” says: in the human body, water is found both outside the cells and inside them.
Intercellular water (water in blood plasma and lymph) makes up 15-20% of the total mass of a person, and intracellular water makes up 50% of the total mass. Extracellular fluid consists of circulating blood, lymph, intestinal juices, cerebrospinal fluid, the liquid environment of the eye and ear, joint and periarticular fluid.
Lymph is a circulating form of intercellular fluid.
With any chronic diseases, the flow of fluid in the body gradually decreases, first in the intercellular environment, and then in the lymphatic system, thereby disrupting the drainage function of interstitial humoral transport (lymphatic system).
Blood and lymph make up only 10% of the liquid part of the body, the rest is water outside the vascular bed. It is clear that when the flow of fluid is delayed in the body, food waste accumulates. Cells are derived from intercellular fluid, and blood delivers nutrition only to the capillaries.
Other dangers
Our health is threatened by the action of other factors of environmental pollution as a result of utilization (petroleum products) and urbanization (high noise level), alcohol and nicotine consumption, high stress levels, increase the need for vitamins, trace elements and other vital substances, the chronic deficiency of which makes the body susceptible to ailments.
In the second half of the twentieth century. diseases called diseases of “civilization” came into fashion: atherosclerosis, heart attack, stroke, hypertension, diabetes, obesity, mental depression.
Reasons:
1. Deterioration of the environment.
2. Change in the composition of food, a lot of sweet, fatty, canned, few vitamins, trace elements. Products of animal and plant origin themselves have also changed.
A lot is said and written about health, but unfortunately few people take it seriously. Most people have become lazy and live as they please, without devoting either strength or time to taking care of themselves.
People do not remember their illnesses in due time and live in a “magnetic field” of temptations, “submissively” surrendering to the power of bad habits.
Nicotine, alcohol, muscular inactivity, unbalanced and irrational nutrition, bad character, overeating, these are the killers, the oppressors of health.
There is a triad: Overeating, Muscular inactivity, Nervous overload. This triad lies at the heart of modern diseases. This is a disease of the body that has failed to adapt to new conditions.
The main provisions of this approach:
1. In most diseases, it is not nature, not the environment, not medicine, but the person himself who is to blame.
2. Do not rely on medicine, it does not treat acute conditions badly, but cannot make a person healthy.
3. Drug therapy has created the illusion of a quick, simple and effective treatment. Put a pill under your tongue and you are healthy.
4. To be healthy requires joint efforts.
5. The human body is so perfect that it is possible to restore health from any of its declines. Efforts should increase as you get older and diseases worsen.
6. Each person, this or that lifestyle, nutrition, the engine of mental activity, mood, determines the duration of his life and state of health.
7. Taking effective drugs helps to eliminate symptoms. In addition, pharmacological drugs often provoke new health disorders with long-term use.
