In my blog article on baking soda for kidney health, I expressed how the kidneys are constantly neutralizing acid produced during metabolism. The kidneys do this by producing about a pound of bicarbonate each day to keep the pH of blood and other body fluids at or near the pH of 7.4, which is a slightly alkaline fluid environment. The reason for this is simple. Our cells, through metabolic reactions, produce hydrogen ions as well as lactic acid. It is the lactic acid that actually produces muscle pains when exercising for a prolonged period of time. Normally, bicarbonate binds these acids, transports them to the lungs where they are eliminated as carbon dioxide. Some acid is also excreted by the kidneys.
However, as efficient as this system is, it can be easily overwhelmed. Primary examples are extensive, prolonged exercise, kidney insufficiency and lung insufficiency of any kind.
HOW ACIDITY AFFECTS US
Too much acidity slows down all metabolic reactions. All metabolic reactions are enhanced (sped up) by enzymes, and enzymes are proteins made of amino acids. Acidity basically denatures proteins (i.e. starts changing their shape) and thus makes them less capable of performing their job. Continue reading
