The Circulatory System
During conditions of excessive acidity or alkalinity, bacteria and/or fungi and/or viruses can attach themselves to the inner wall of arteries, which then attracts white blood cells, clotting proteins, clotting cells, etc. This can cause a plaque to form in the artery, thus narrowing the artery and restricting the flow of blood, oxygen and nutrients to the tissues supplied by that artery. If the coronary artery is involved, a heart attack can occur. If excess acidity is present, calcium, which was mobilized out of the bone to buffer the acid, can deposit in the arterial plaque, thus converting the plaque from soft to hard. The plaque makes the arteries stiff, which can raise blood pressure.

The Nervous System
When brain cells are too acidic or too alkaline, they dysfunction, resulting in inability to produce the appropriate chemicals (neurotransmitters) to communicate with adjacent brain cells. This can result in insomnia, anxiety, depression, neuroses, psychoses and impairment of memory. Since the brain is supposed to communicate through the spinal cord and other nerves to every cell in the body (heart cells, intestinal cells, muscle cells, glandular cells, etc.), every body system can dysfunction if the nervous system does due to acid/alkaline imbalance.

The Structural System
The calcium stored in the bones is released when serum and soft tissue calcium is used up, binding and neutralizing excess acid in the tissues. This initial calcium depletion in the muscle can cause muscle cramps. But as calcium is pulled from the bone to neutralize more acid, the bone stores of calcium become depleted causing osteoporosis, weakened and collapsed vertebrae and, often, poor back posture and back pain. The calcium mobilized from the bone gets deposited as calcium-acid salts in the joints, leading to degenerative arthritis.

The Digestive System
When the pH is too acidic or too alkaline, the cells lining the stomach and small intestines and the cells in the pancreas that are responsible for producing and releasing digestive enzymes dysfunction resulting in indigestion, gaseousness, bloating and abdominal cramping. Not enough nutrients get absorbed from the food, and the entire body can experience malnutrition. Also, undigested foods ferment in the intestines causing toxicity.

The Intestinal System
Excessive acidity or alkalinity causes the colon cells to dysfunction, which can result in diarrhea, irritable bowel syndrome, constipation or diverticulitis. The disturbed acid/alkaline balance in the colon can also cause unfriendly microbes to grow and thrive, which can result in colitis, inflammatory bowel disease (including Crohn’s) or hemorrhoids.

The Immune System
Immune cells that are too acid or too alkaline do not produce antibodies or cytokines (chemical messengers to regulate other immune cells), and they have impaired phagocytosis (the ability to engulf and destroy microbes). As a result, the affected individual becomes susceptible to viral, bacterial, fungal and other infectious microbes as well as cancer.

The Respiratory System
The binding of oxygen to the hemoglobin protein of red blood cells in the lungs operates only at a fairly narrow pH range. If the pH is too acidic or too alkaline, microbes in the airways can grow much more easily, invade human cells, cause bronchitis, pneumonia, sinusitis, etc., and in doing so, can result in cough, bronchial spasms (asthma) and increased susceptibility to allergens (hay fever).

The Urinary System
The urinary system helps eliminate toxic waste products from the body. Women especially (because of their short urethra connecting the urinary bladder to the exterior of the body) have some bacteria and/or fungi in their bladder. These microbes can grow rapidly if the urine’s pH is not in the proper range most of the time. In acid-excess conditions, calcium, which is mobilized from the bone to buffer the acid, can form calcium crystals and stones in the kidney collecting system. When these stones dislodge and pass down the urethra towards the bladder, they usually cause excruciating pain.

The Glandular System
All of the endocrine glands produce hormones from enzymatic action. If the pH is too acidic or too alkaline, the glandular cells cannot produce and release sufficient hormones for the body’s needs. This results in mood swings, blood sugar imbalances, fatigue, reproductive difficulties, etc.

Vital Nutrition
The late Roger William, Ph.D. at University of Texas–Austin, popularized the principle of biochemical individuality. He found that in an average group of 20 humans, there was a seven-fold difference between the lowest amount of a particular vitamin or mineral required by one of those individuals in order to maintain health and the lowest amount of that same vitamin or mineral required by another individual in that group of 20 people. Diet no longer contains sufficient micronutrients (vitamins and minerals) to maintain health, because most foods are now grown on mineral-depleted soil that has been over-farmed for decades, and adequate minerals are required by the plants to produce adequate vitamins in the plants.
