Can blood have normal PH levels regardless of what we consume? Just asking. So even if we only consume acid our bodies could still have blood other day very acidic blood? Just asking for info/opinions.
Read the full article for a better idea of what's going on.
The pH of your blood is tightly regulated by a complex system of buffers that are continuously at work to maintain a range of 7.35 to 7.45, which is slightly more alkaline than pure water.
If the pH of your blood falls below 7.35, the result is a condition called acidosis, a state that leads to central nervous system depression. Severe acidosis - where blood pH falls below 7.00 - can lead to a coma and even death.
If the pH of your blood rises above 7.45, the result is alkalosis. Severe alkalosis can also lead to death, but through a different mechanism; alkalosis causes all of the nerves in your body to become hypersensitive and over-excitable, often resulting in muscle spasms, nervousness, and convulsions; it's usually the convulsions that cause death in severe cases.
The bottom line is that if you're breathing and going about your daily activities, your body is doing an adequate job of keeping your blood pH somewhere between 7.35 to 7.45, and the foods that you are eating are not causing any wild deviations of your blood pH.

When you ingest foods and liquids, the end products of digestion and assimilation of nutrients often results in an acid or alkaline-forming effect - the end products are sometimes called acid ash or alkaline ash.
Also, as your cells produce energy on a continual basis, a number of different acids are formed and released into your body fluids. These acids - generated by your everyday metabolic activities - are unavoidable; as long as your body has to generate energy to survive, it will produce a continuous supply of acids.
So there are two main forces at work on a daily basis that can disrupt the pH of your body fluids - these forces are the acid or alkaline-forming effects of foods and liquids that you ingest, and the acids that you generate through regular metabolic activities. Fortunately, your body has three major mechanisms at work at all times to prevent these forces from shifting the pH of your blood outside of the 7.35 to 7.45 range.
These mechanisms are:
It's not in the scope of this post to discuss the mechanisms listed above in detail. For this article, I only want to point out that these systems are in place to prevent dietary, metabolic, and other factors from pushing the pH of your blood outside of the 7.35 to 7.45 range.
- Buffer Systems
- Carbonic Acid-Bicarbonate Buffer System
- Protein Buffer System
- Phosphate Buffer System
- Exhalation of Carbon Dioxide
- Elimination of Hydrogen Ions via Kidneys
When people encourage you to "alkalize your blood," most of them mean that you should eat plenty of foods that have an alkaline-forming effect on your system. The reason for making this suggestion is that the vast majority of highly processed foods - like white flour products and white sugar - have an acid-forming effect on your system, and if you spend years eating a poor diet that is mainly acid-forming, you will overwork some of the buffering systems mentioned above to a point where you could create undesirable changes in your health.

And yes, generally the science is understood. (not by me, but by those who study it.)
