Alkaline nutrition is a topic that has become increasingly popular in recent years and is open to research, and it is frequently encountered both in social media and in academic studies in the literature.
The basis of the alkaline diet is based on the principle of consuming less of some foods and more of some foods. alkaline diet; reducing the consumption of meat, milk and its products, eggs, whole grains and processed foods; recommends increasing the consumption of vegetables, fruits and legumes. (about 1/4 of it) In the content of alkaline diet, the consumption of sugar, salt and meat is not completely prohibited, only the amount is reduced. It is argued that organic foods should be preferred instead of foods exposed to pesticides, antibiotics and hormones in acid form. 1 liter of alkaline water should be consumed per 20 kg. It is stated that as a result of reducing acidity with such a diet, weight loss in the body and optimal health will be improved. Although there is little evidence for weight loss, it is said that it may be beneficial on bones and kidneys with the nutrients it contains.
Those who do not support the alkaline diet criticize the restrictive aspects of the alkaline diet and emphasize that it can lead to eating disorders such as malnutrition or orthorexia.
PH CONCEPT:The pH in the body is graded from 1 (most acidic) to 14 (most alkaline), with a neutral pH of 7 and the optimal pH in the blood is in the range of 7.2-7.4
If people’s diets do not contain enough calcium, magnesium, potassium and other acid-buffering minerals, these minerals are withdrawn from the stores of tissues such as bones, liver and heart and can cause serious problems. Generally, individuals are poor in magnesium, potassium and fiber; It is rich in saturated fatty acids, simple sugars, sodium and chloride. This type of nutrition decreases renal acid-base regulatory functions and as a result, diet-induced metabolic acidosis increases. Low-carbohydrate and high-protein diets increase the acid load and cause changes in the urinary system; It causes changes in blood and pH level. Thus, while urinary magnesium, citrate and pH levels decrease; urinary calcium, undissolved uric acid and phosphate levels increase. All these results increase the risk of stone formation in the kidney.
Rising on an alkaline diet bicarbonate(without potassium) has been found to alleviate bone loss in healthy older people As a result of the systematic review article in the current literature, there is evidence that alkaline diet is not protective against dietary acid load for bone health in osteoporosis.
Excessive protein intake in the diet creates a high renal acid load; If alkali-rich foods or nutritional support are not taken, the buffering system cannot be activated and the resulting acid load reduces bone density.
As a result;
Increasing fruit and vegetable consumption rather than reducing protein intakemay be more accurate.
The effects of foods that are considered acid and alkaline in the body are different.
Especially positive effects on bone, calcium metabolism and acidosis were observed.
Although studies continue, there is no clear information supporting alkaline nutrition, there are discussions.
More research and clarification is needed as there are advocates and opposing views.
