Human body is slightly alkaline by design. When maintained alkaline, the body will be able to perform, at its optimal level, all the activities that sustain life. This include the physiological and metabolic processes, as well as the continuous detoxification of the body.
If the body becomes over-acidic, it can no more work properly. Toxic by-products will accumulate. This bring out chronic diseases: cancer, diabetes, heart diseases, and many more.
Balanced nutrition is the one that brings to our body the different nutrients and elements needed for our metabolism and physiology to run the optimal way, and to develop and maintain, as a result, a life with vibrant health and wellness. To get our modern acidic diet balanced, we need to add to it, however, on a regular base a number of nutritional supplements.
One of the key nutritional balances to keep is the body acid-alkaline balance commonly referred to as pH. The pH of any water solution is the measure of its hydrogen-ion concentration. The pH ranges from 0 to 14, with 7.0 being neutral. Any solution below 7.0 is acidic and a solution above 7.0 is alkaline. From pH 7.0, when the pH of a solution decreases, the solution becomes more acidic, and when the pH increases, the solution becomes more alkaline.
Water is the most abundant compound in the human body (up to 55% of the body mass). The body contains indeed a wide range of solutions termed physiological fluids. In balanced conditions, each of those fluids may be less or more acidic. Human physiological fluids include the intracellular fluid (2/3 of the body water mass) and the extracellular fluid (1/3 of the body water mass).
The extracellular fluid includes the blood (or blood plasma, to be more precise, 1/5 of extracellular fluid), the interstitial fluid (4/5 of extracellular fluid), and a number of the so called transcellular fluids found inside some particular organs, like the urine and the saliva.
Physiological fluids support normal physiology by carrying nutrients, oxygen and wastes throughout the body. In addition, they constitute the media within which almost all biochemical reactions (metabolism) take place. Therefore, any acid/alkaline imbalance will have throughout the body a generalized negative impact. This stress may impair our normal metabolism and physiology, as well as our immune system. It might provoke over time in the body a series of degenerative diseases.
Scientific research reveals that the pH of the normal human intracellular fluid is roughly 7.0, whereas the pH range of extracellular fluid (including blood) is 7.35-7.45. The pH ranges of these two main body fluids show that to expect optimal metabolism and physiology, and to stay healthy, our body (blood and body tissues included) should maintain all the time a balance between acids and alkalis, with a slight excess of the alkalis over the acids.
In contrast, our normal urine should range from very slightly acidic, to very slightly alkaline (pH 6.50-7.50). The fact for the urine being slightly acidic indicates that the body is eliminating the excess of acids, which are natural by-products of our metabolism.
Thus, the body strives continuously to balance the pH, and to keep it within the normal ranges. A key concept of physiology is homeostasis. This term indicates how all the body parts and processes are linked together. Therefore, when the blood comes to be too acidic, as to its ideal pH range, the other body fluids will also show to be too acidic, in respect to their individual optimal pH ranges. The same situation occurs when the blood is too alkaline. Medicine names acidosis the situation where the body is too acidic. This condition is far the most frequent. The case where the body is too alkaline is called alkalosis; it is in contrast uncommon.
