Thank you for the opportunity to help you with your question!

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 6.8 or above 7.8, cells stop functioning and the patient dies. The ideal pH for blood is 7.4

A healthy blood pH without cancer has acid + alkaline balance almost equal. Actually a healthy body is slightly alkaline measuring approximately 7.4. This ideal  blood 7.4 pH measurement means 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).

If you have a health problem, most likely you are acidic. Research shows that unless the body's pH level is slightly alkaline, the body cannot heal itself. So, no matter what type of modality you choose to use to take care of your health problem, it won't be as effective until the pH level is up. If your body's pH is not balanced, you cannot effectively assimilate vitamins, minerals and food supplements. Your body pH affects everything.

Please let me know if you need any clarification. I'm always happy to answer your questions.
