alkaline diet or alkaline diet is a diet plan that emphasizes the consumption of fresh vegetables and fruits in order to maintain the desired pH level in the body. This diet is based on the hypothesis that foods can change the body's pH to be acidic or alkaline. Proponents of this diet believe that foods leave an acidic or alkaline ash after metabolism, which affects the body's pH. These people believe that increasing the consumption of alkaline foods is effective in preventing some diseases.
In medicine, an alkaline diet is used to prevent kidney stones and urinary tract infections. However, it is important to note that there is not much scientific evidence to support most of the claims made about the benefits of this diet. Because the body has many mechanisms to maintain pH stability. In this article from BingMag Meg online magazine, we will introduce the alkaline diet in full. If you decide to start this diet plan, be sure to follow us to the end.

What is an alkaline Diet?
alkaline diet It is also called "alkaline". It is thought that this diet can change the pH of the body (the degree of acidity or alkalinity). In the alkaline diet, food intake is not limited to certain times of the day. Rather, people who follow it are taught to increase their intake of alkaline foods and reduce their intake of acidic foods.
Sometimes metabolism is compared to fire. Because both involve a chemical reaction that breaks down a solid mass. However, chemical reactions in the body occur slowly and in a controlled manner.
When fire burns everything, ashes remain. In your body, too, the foods you eat leave ash-like debris called metabolic wastes. These metabolic lesions can be alkaline, neutral or acidic. Proponents of the alkaline diet claim that metabolic wastes can directly affect the body's acidity. In other words, if you eat foods that leave acidic ash, your blood will become more acidic. But if you eat foods that produce alkaline ash, your blood will become more alkaline.
According to the acid-ash hypothesis, acid ash exposes you to various diseases, while alkaline ash protects your health. protects. Therefore, you can make your body alkaline and improve your health by choosing foods that are more alkaline.
The components of food that leave out acidic ash include protein, phosphate, and sulfur. In contrast, calcium, magnesium and potassium are the alkaline components of foods. Food groups can be divided into three categories: acidic, alkaline and neutral:
- acidic: Meat, poultry, turkey, fish, dairy, eggs (especially yolks), Cereals, lentils, peanuts, walnuts, alcohol, ice cream, soft drinks and other processed foods
- Neutral: Starchs, sugars and natural fats (such as olive oil, cream and butter)/li>
- Alkaline: Fruits, unsweetened juices, nuts, legumes, soy, grains, and vegetables
Some prescriptions of the alkaline diet are less strict. This means that cereals, although slightly acidic, may be allowed to be eaten because of their health benefits. But in general, if you follow an alkaline diet, you should avoid acidic foods, limit neutral foods and eat more alkaline foods.
What is the body's normal pH?
When talking about an alkaline diet, it is important to understand the concept of pH. Simply put, the degree to which something is acidic or alkaline is called pH. The pH value varies from 0 to 14. Lower numbers indicate more acidic and higher numbers indicate more alkaline:
- acidic: 0 to 6/9
- neutral: </7>
- Alkaline: 1/7 to 14
Many proponents of the alkaline diet suggest that people adjust their pH by Use a urine test strip to make sure it is alkaline (more than 7) and not acidic (less than 7). However, you should keep in mind that your body pH is very different. While some parts of the body are acidic, some areas are alkaline and there is no definite level.
The stomach is full of hydrochloric acid and therefore very acidic and its pH is between 2 and/5 is. This amount of acidity is necessary for the breakdown and digestion of food. On the other hand, human blood is always slightly alkaline and its pH is 36.7 to 44.7. When the pH of the blood is out of the normal range, not treating it can be fatal. These conditions only occur due to certain problems such as "ketoacidosis" that results from diabetes, extreme hunger or alcohol consumption.
When the body is unable to consume carbohydrates due to problems such as insulin deficiency and instead Using fats as a source of fuel, the body produces substances called ketones, the accumulation of which leads to ketoacidosis.
What effect do foods have on the pH of urine and blood?
Maintaining blood pH is very important for maintaining good health. If the pH of the blood is supposed to be out of the normal range, your cells will fail and die very quickly if left untreated. Because of this, there are many effective ways in the body to fine-tune pH balance, known as "acid-base homeostasis." In fact, in healthy people, it is impossible for food to control blood pH. Change, although slight fluctuations may occur within the normal range. However, food can change the pH of the urine. However, the extent of its effect varies somewhat.
Excretion of acids in the urine is one of the main ways that the body uses to regulate blood pH. If you eat a large steak, your urine will become more acidic in a few hours. Because the body excretes metabolic wastes. Therefore, urine pH can not reflect the overall pH of the body and general health status. On the other hand, it may be influenced by factors other than diet.
Acidic foods and osteoporosis
Osteoporosis is a progressive bone disease characterized by a decrease in bone mineral content. It is especially common in postmenopausal women and can greatly increase the risk of bone fractures. Many proponents of the alkaline diet believe that to maintain a stable blood pH, the body removes alkaline minerals such as calcium from the bones to neutralize the acids in acidic foods eaten.
According to this theory, diets Acids such as the standard Western diet reduce bone mineral density. This theory is known as the "osteoporotic acid hypothesis". However, this theory ignores the function of the kidneys, which are essential for the elimination of acids and the regulation of the body's pH. The kidneys produce bicarbonate ions, which neutralize acids in the blood and allow the body to control the pH of the blood more precisely.
Your respiratory system also plays a role in controlling the pH of the blood. When bicarbonate ions bind from the kidneys to acids in the blood, they form carbon dioxide and water, the former of which is excreted in the exhaled and the latter in the urine.
The acid-ash hypothesis is the same. Ignores one of the main triggers for osteoporosis, which is a decrease in bone collagen protein. Collagen depletion is associated with a deficiency of two acids in the diet, orthosilicic acid and ascorbic acid, or vitamin C. Remember that there is scientific evidence for a link between dietary acid and Contradictory with bone density or fracture risk. Although no correlation has been found in many studies, some research has identified a significant correlation. More careful clinical studies have concluded that acidic diets have no effect on the body's calcium levels.
An acidic diet with low calcium intake causes bone problems. But if the calcium level is high, the acidic diet may have a protective effect. This type of diet improves bone health by increasing calcium retention and activating the hormone IGF-1, which helps repair muscles and bones. Therefore, a high-protein, acid-producing diet may be linked to maintaining bone health.

Acidity and cancer/h2>
Many people believe that cancer only occurs in an acidic environment and therefore it can be Treated with an alkaline diet. However, scientific research on the relationship between dietary acidosis (increased blood acidity due to diet) and cancer has concluded that there is no link between the two. Because food does not have a significant effect on blood pH. On the other hand, even if it can have such an effect on the pH of the blood or other tissues, the cancer cells are not confined to acidic environments. In fact, cancer is a natural tissue in the body that has a relatively alkaline pH (4.7). Is, is created. In many experiments, researchers have been able to successfully grow cancer cells in an alkaline environment. Although tumors grow faster in acidic environments, they produce this acidity themselves. In other words, it is not the acidic environment that causes cancer cells, but the cancer cells that cause the acidic environment.

Did human ancestors have an alkaline diet?
The alkaline diet bears a striking resemblance to the Paleo diet because of its emphasis on eating fruits and vegetables instead of processed foods. The Paleo diet is a diet based on the eating habits of our hunter-gatherer ancestors. But research does not necessarily support the idea that our early ancestors used an alkaline diet.
One study estimated that 87% of humans had an alkaline diet before they started farming. But recent research shows that during this period, about half of the people were on an alkaline diet and the rest on an acidic diet. Evidence suggests that place of residence may have influenced the type of human diet. According to researchers, the farther away people live from the equator, the more acidic their diet becomes.
For whom is the alkaline diet safe and harmful?
A flexible version of the alkaline diet that does not impose severe restrictions on nuts and whole grains is good for your health. In general, a plant-based diet reduces the risk of many cancers, heart disease, stroke, and type 2 diabetes. For people with a history of kidney stones or kidney disease, a plant-based diet, not necessarily an alkaline diet, may be helpful.
An alkaline diet is safe for healthy people. But some people feel hungry or do not get enough protein to meet their body's needs. In addition, healthy foods may be excluded from the diet. Some acidic foods such as eggs and walnuts are perfectly healthy. Eliminating these items from the diet will deprive many people of nutrient-rich foods.
alkaline diet is not designed for weight loss, and if you do not know how to get enough protein from plant-based foods, you may You will feel very hungry during the day. Therefore, it is best to consult a nutritionist before starting this diet to make sure that you do not eliminate important nutrients from your diet and do not inadvertently damage your health.

alkaline diet is perfectly healthy. Because it encourages increased consumption of healthy fruits, vegetables and plant foods, while limiting unhealthy processed foods. However, the notion that diet improves health due to its alkaline effects is not acceptable. Because these claims have not been corroborated by any credible human studies, there is no credible evidence that diet is related to pH levels.This is for educational and informational purposes only.
