I have been teaching the importance of understanding acid and alkaline for more than 25 years. It’s a great concept, and is getting more and more attention.
We know that pH is the measure of acid and alkaline (or basic) substances, mostly fluids. It is not exact, but an approximation. A pH of 7 is considered neutral, neither acid nor alkaline. This is the pH of water. Now let’s remember that the acids and bases (alkalis) of the body need to be in very close balance – this is called “acid-base homeostasis.” If it goes off too far in either direction, it may be fatal. In the body, the blood has a pH range of 7.35 to 7.45. If it goes down to 6.9, one dies of diabetic coma. If it goes up to 7.9, one dies of tetany, or lock-jaw. Keep this in mind whenever you read certain authors that insist that we should always be tilting towards alkaline – an excess of either is dangerous (there is a book called “Alkalize or Die” – a preposterous title, as, no matter what we do, we all will, eventually, die). The body strives towards homeostasis or balance. It’s like riding a bicycle.
