Acidification of the organism, pH and alkaline diet. Feeding people lies that can only be seen sourly
Basics and functioning of our body
The body regulates the pH and it's damn good at it. The pH of human blood is in the range of 7.35 - 7.45. If it was less (acidosis) or more (alkalosis), a serious problem arises that you would really notice before you had to pee on litmus paper and send this information to your trainer - an expert on the body.
If you eat something, acidic H + ions are formed. Fortunately, you're not dead, your body works, so it uses a bicarbonate buffer system. This "buffer" system in the blood, respectively. buffers (der Puffer - buffer, buffer) regulate the pH of the system to produce substances that are subject to metabolism. For example, increased or decreased carbon dioxide excretion is regulated by the lungs. Then you also have kidneys in your body, which, among other things, excrete acidic H + ions in the urine in exchange for basic bicarbonate, which is reabsorbed into the blood. Is acid urine a problem? No, it's a waste product of your body and has nothing to do with blood pH. Dealing with the pH of your urine is like dealing with the taste of your other waste product, but it's starting to get disgusting.
Someone will say that acidification is a real deal, because there is acidosis in the body. However, acidosis is only a short-term condition that can be balanced very quickly. If not, it is the result of serious disorders that can lead to death. How can acidosis occur? If the body cannot effectively get rid of excess hydrogen cations, which can be caused by either reduced breathing intensity or insufficient kidney function. Acid-base balance is regulated by your body. If it lasts longer, not even a cucumber or kohlrabi will help you to remove meat from the menu. Because if it lasts longer, it means that you are suffering from a more serious disorder. And no, this disorder does not result from not following the rules of an alkaline diet.
Alkaline diet
It is based on the theory that when certain foods are eaten, they are metabolized in the body to form base-forming or acid-forming residues (pH). When there is an excess of acidic food, there is an acidification of the blood, and this is said to affect our bones, organs, contribute to cancer, obesity and the like. Therefore, you have to wait for the litmus paper, which determines the pH. We put our hand into the fire, that it will be acidic, in which case the expert will set you an alkaline diet.
Are you missing something on the left side of the picture? Believe me, it's missing. Proponents "unintentionally" omitted nutritionally valuable foods such as dairy products, nuts, seafood or whole grains. Since there are a ton of fruits and vegetables on the right, the acidic environment / food on the left seems bad. In this way, it is very easy to influence the masses. However, be aware that there is nothing wrong with acids. They shape many building blocks for life. Yet we have amino acids, omega-3 fatty acids, or even DNA, which is nothing more than deoxyribonucleic acid. There are no foods that would significantly affect the pH of the body's internal environment. You eat, digest, then are absorbed and only then can they affect the pH of the human body.
The stomach contains hydrochloric acid and has a pH of about 1.35 - 3.5 (extremely acidic) and is subsequently neutralized by alkaline secretions of the pancreas. This process breaks down food into the basic ingredients, which are absorbed and could theoretically affect the pH. But they do not affect! Eating acid-forming foods does not affect blood pH.
In the stomach and small intestine, nutrients are broken down. Proteins for amino acids, carbohydrates for monosaccharides and fats for fatty acids and glycerol. Monosaccharides and fatty acids do not affect the pH, so even a food that combines these nutrients will not form an acid- or base-forming food. And what about proteins? Within amino acids, only aspartate and glutamate are acidic. Lysine, histidine and arginine are basic. Other? Neutral. However, no sources of protein are made up of only one amino acid, so the effect of proteins will be close to neutrality. So again - the internal environment of the body is not affected by any food.
Why does someone feel better on an alkaline diet? Maybe a placebo. Perhaps the usual replacement of an idiotic diet with one that is rich in quality nutrients, vitamins, minerals and fiber. However, an alkaline or acidic environment has nothing to do with your weight loss. You can't lose weight because you are stupid, you don't have enough nutritious food in your diet and you're in caloric excess.
I've heard that an alkaline diet helps with osteoporosis!
He could hear, but know it was a fabrication. Although the average IQ and basic knowledge of biochemical facts are enough for the topic of acidification of the organism, let's take a look at something. A meta-analysis covering 55 studies showed that the causal link between the acidic environment and osteoporosis is not substantiated and there is no evidence that an alkaline diet protects the health of our bones. So if you found the theory of balancing the pH with minerals that are released from the bones as real, refresh your face with ice water and know that the pH is balanced by blood buffers and subsequently the kidneys.
Cancer
Not. Although fans of the alkaline diet will tell the storytellers that an acidic environment creates cancer, don't believe it. It is cancer that creates an acidic environment, not the other way around. An acidic environment is the result of cancer, not its cause! If our internal environment is acidic (that is, acidosis occurs), it is caused by various metabolic disorders, whether cancer has developed. In fact, having an acidic internal environment is basically impossible because you would die. And again, if ordinary logical facts are not enough for you, take a look at the systematic analysis of the association between acidity, alkaline water and cancer. The findings say that although some vendors are promoting an alkaline diet or water, there is no research to support these ideas. Also, there is no evidence that they help treat cancer.
I know that for a person studying medicine, nutrition or a lover of biochemistry, this topic is clear and all the benefits of an alkaline diet are that one starts eating more fruits and vegetables, but it had to be said out loud. People like to jump on a train where the driver is an unsuccessful blogger or editor of a women's magazine without knowledge of nutrition.
