Dietary imbalances and the presence of environmental toxins, sometimes introduced into the food chain, are factors related to changes in urine pH which, in turn, are determining factors for the formation of kidney stones. This explains the high incidence of this pathology in developed countries.
It has been considered that there are a series of foods that acidify urine (urine pH below 7), such as meat, fish, eggs, cheese, animal fats, vegetable oils, cereals, sweets, coffee, tea, or alcohol; while others alkalinize it (urine pH above 7), such as fruits, vegetables, or potatoes. However, the greater or lesser consumption of these foods must be determined by the need to alkalinize or acidify the urine to prevent and correct urinary pH imbalance and ensure that it is within the preventive range for certain urological diseases.
For example, kidney stones have a preventive urinary pH range between 5.5 and 6.2, since uric acid and calcium oxalate kidney stones usually form when urine is acidic, or urinary infections can be detected if urinary pH is high. Therefore, to maintain urinary pH balance, it is as important to know its value as it is to adopt some measures to correct it and prevent associated complications.
Therefore, to balance it, we must follow a varied, balanced diet, adapted to each person and free of toxins and/or through appropriate food supplements that allow restoring the acid-base balance of the urine, maintaining a good functioning of the pH regulation systems and, therefore, of the entire organism.
