Since both bad bacteria and cancer thrive in an acid environment, test your own acid/alkaline balance in saliva and urine with over the counter p.H. strips. Optimal ranges are between 6.5 and 7.5 taken first thing in the morning before breakfast. If measurements are out of range, consider decreasing starchy carbs, sugar, meats and dairy and increasing whole, organic fruits and veggies. Also, increasing oxygenation through moderate daily exercise supports a more alkaline system.
