This book proves how important it is to have the body fluids slightly alkaline and tells you how to test yourself so you maintain a proper balance. It also proves that calcium is the most important nutrient after oxygen and water because calcium carries the other nutrients into the cells. "Over 200 diseases are linked to IONIC CALCIUM DEFICIENCY: Cancer, Diabetes, Arthritis, Heart Disease, Osteoprosis, Alzheimer's Disease, Fibromyalgia, Chronic Fatigue Syndrome...And Many, Many More. Acidosis (overly acid body) is the primary indicator of I.C.D.D. - IONIC CALCIUM DEFICIENCY DISEASE. Scientists have discovered that the body fluids of healthy people are alkaline (high pH) whereas the body fluids of sick people are acidic (low pH). 'Calcium deficiency is the universal property of all cancer cells.' CALCIUM IN BIOLOGICAL SYSTEMS (vol 1, l985, CRD Press, Inc.) 'The early work of Otto Warburg, some 60 years ago (CAUSE AND PREVENTION OF CANCER; Biochem Zeits, 152:514-520, 1924), showed that cancer was associated with aenerobic (deficiency of oxygen) conditions, resulting in fermentation and a drop in the pH of the cell. (LOW pH HYPERTHERMIA CANCER THERAPY, Cancer Chemotherapy Pharmacology 4; 137-145, 1980). Moreover, the production of mutation receptors cannot occur with the pH of the cell in the healthy, calcium buffered 7.4 to 6.6 range." I have an interview with Robert Barefoot that I would be willing to send FREE to those who care.
