In the body fluids and cells acids and bases are constantly in a certain balance. On a scale of 1-14, pH 7 is the neutral acid-base ratio. Acid means a pH below 7, alkaline means a pH above 7. I will give you some examples of standard values:
blood: pH: 7.37 to 7.43
bile: pH: 7.4 to7.7
urine: pH: 4.8 to 7.9
gastric juice: pH: 1.2 to 3.0
Due to its great importance, the body has several systems to keep the acid-base balance in equilibrium. The final adjustment happens by excretion through the kidneys and exhalation of CO2 through the lungs.
The greatest fluctuations in the acid-base balance are caused by food. Here it is irrelevant whether the food tastes sour; important is whether in the process of the metabolism more acids or bases are produced. Animal food (other than milk), grains, coffee, sugar and alcohol produce acids. Wholefood, fruits, vegetables and legumes, however, produce more bases. The more acid exposure through a poor diet, the more likely an acidosis of the body will happen.
It is easy to measure whether you are too acidic. Measure the acid value of the morning urine right after getting up. Ideally, the value is slightly basic, above a value of 7. Values of 6.5 are still ok. Values below 5.5. are critical. If the urinary pH is below 4.5, kidney cells will inevitably be damaged. The acidity of the urine varies naturally because certain degradation products are excreted in a more acidic and others in a more alkaline medium. The urine should be not only alkaline or acidic. Decisive for the assessment is not a single value; values should be recorded for a period of 14 days. Based on these values, you can determine whether a treatment is necessary.
A typical disease arising from this situation is gout. Due to a high level of uric acid in the blood, there will be crystalline deposits on joints and connective tissue. This leads to painful inflammation and joint destruction.
