The term “pH” is an abbreviation for potential hydrogen.
The pH of any solution is the measure of its hydrogen-ion concentration.
The higher the pH reading, the more alkaline and oxygen rich the fluid is.
Conversely, the lower the pH reading, the more acidic and oxygen deprived the fluid is.
The pH range is from 0 to 14, with 7.0 being neutral.
Anything below 7.0 is considered acidic; while anything above 7.0 is rated alkaline;
Human blood stays in a very narrow pH range right around ( 7.35 – 7.45 ).
Below or above this range means symptoms and disease.
If blood pH moves to much below 6.8pH or above 7.8pH, cells stop functioning and the patient dies.
The ideal pH for any human blood is 7.4; and this means that it is just slightly more alkaline than acid.
Thus, a healthy blood pH (without cancer) has almost equal acid + alkaline balance. (i.e. pH = 7.4).
Actually, a healthy body is slightly alkaline measuring approximately 7.4 and slightly above.
This is because the ideal blood 7.4 pH measurement means that it is just slightly more alkaline than acid.
The pH in the human digestive tract varies greatly (see Human Digestive Tract pH Range Chart on the left side).
The pH of saliva is usually between 6.5 – 7.5.
After we chew and swallow food, it then enters the fundic or upper portion of the stomach which has a pH between 4.0 – 6.5. This is where “predigestion” occurs while the lower portion of the stomach is secreting hydrochloric acid (HCI) and pepsin until it reaches a pH between 1.5 – 4.0. After the food mixes with these juices it then enters the duodenum (small intestine) where the pH changes to 7.0 – 8.5. This is where 90% of the absorption of nutrients is taken in by the body while the waste products are passed out through the colon (pH 4.0 – 7.0).
