Alkaline ash foods include some fresh fruit and raw vegetables, and tubers. Acid ash foods include all animal products, whole grains, beans and other seeds, fungi and processed oils.
The body must buffer or eliminate
If the body eliminates it does through lungs, kidneys, and skin
If the body buffers it may do so through mineral mass like calcium from the skeleton or bicarbonate in the blood.
The Organs of pH Balance All of these systems must function efficiently to maintain optimal acid base balance. If there is an impairment in one of these systems, or if the daily production of acids is too high to be buffered appropriately, the cells and tissues become too acidic.
Buffer and Eliminate ion trapping, xenobiotics, toxins, drugs
The Cortisol Connection Swiss Study Acidogenic, Western-type, diet for nine days Elevated stress hormones like cortisol. Subjects given Bicarbonate supplements and cortisol levels dropped to normal.

Acidosis is associated with gut barrier dysfunction , as well as free radical production and chronic oxidative stress. A hyperpermeable gastrointestinal tract has been associated with many different diseases

Quackwatch Has many valid points but misses the big picture
Quackwatch “ When you take in more protein than your body needs, your body cannot store it, so the excess amino acids are converted to organic acids that would acidify your blood. But your blood never becomes acidic because as soon as the proteins are converted to organic acids, calcium leaves your bones to neutralize the acid and prevent any change in pH. Because of this, many scientists think that taking in too much protein may weaken bones to cause osteoporosis.”
