According to Annelie Pompe, a prominent mountaineer and world-champion free diver, alkaline tissues can hold up to 20 times more oxygen than acidic ones. When our body cells and tissue are acidic (below pH of 6.5-7.0), they lose their ability to exchange oxygen, and cancer cells just love that. Researchers found that an increase of 1.2 metabolic units (oxygen consumption) was related to a decreased risk of cancer death, especially in lung and gastrointestinal cancers.
Dr. Robert J. Gillies and his colleagues have already demonstrated that pre-treatment of mice with baking soda results in the alkalization of the area around tumors. The same researchers reported that bicarbonate increases tumor pH and inhibits spontaneous metastases in mice with breast cancer. It also reduces the rate of lymph node involvement.
Cells function in a narrow range of pH and when they get too far out of that comfort zone they become cancerous. When cells lose their oxygen, they are losing their pH and voltage at the same time. When cell voltage is low and oxygen decreases, we see an increase of anaerobic bacteria in the gut, which begins to thrive in the low-oxygen environment.
It is important to understand that the voltage of cells and tissues is synonymous with their pH. The lower the voltage goes, the lower the pH goes, and the lower oxygen levels go as well. Wherever the body has low voltage, the cells begin to have problems that get more serious the lower the voltage (pH) goes.
Bicarbonate in water is the healthiest water to drink. It is critical to see that alkalinity does not depend only on pH. pH measures the degree of alkalinity but not its power. It is not enough to drink high pH alkaline water - in fact pH is not a big factor at all when one is trying to alkalize the body (just "think" lemon juice, apple cider vinegar and fresh green juices - all of which have an acid pH but are still great for alkalizing!).
Water expert Robert Slovak wrote, "Baking soda is still beloved! It delivers the goods - real alkalinity - while most popular alkaline pH drops from well known "health experts" are a hoax at $35-$40 for pennies worth of caustic chemical in 2oz of water. Just note that for some people baking soda (sodium bicarbonate) may supply too much sodium so they can substitute potassium bicarbonate or mix the two."
Bottom line—if you want to live longer and be healthier use sodium and potassium bicarbonate on a regular basis. This is not a casual recommendation for research published recently in the Clinical Journal of the American Society of Nephrology found that having balanced bicarbonate levels in your body reduces chances of an early death. The study examined data compiled in the Health, Aging and Body Composition Study for 2,287 participants.
