Mildly acidic compounds are needed within our bodies to keep tissues firm and supple. But if the acidity is overdone, we would have rigid and dry tissues, hardened arteries, hypertension, gout, arthritis, stiffness, pain, anxiety, tension, osteoporosis, kidney stones, insomnia and elevated odds of cancer and infection. On the other hand, a mildly alkaline state creates fluidity, flexibility and relaxation in the body. If alkalinity is overdone, though, we could experience nausea, tissue deterioration, hallucinations, lethargy and mental instability.
