The acidity in soda is primarily from sodas that contain Phosphoric Acid, which eats bones & teeth. Ever put a tooth in a glass of Coca Cola? (hint: it dissolves the tooth rather quickly)
Also the high fructose corn syrup and/or sugar content in most sodas is very acidic.
Lemons have a pH of 2, which is very acidic, but somehow this is converted in the body to alkaline (would love to understand this better). Lemon water can cause damage to tooth enamel, so be sure to brush your teeth regularly if you are drinking lemon water.
That said, the Lyme spirochettes do secrete Ammonia, which is an alkaline substance. So there will always be those with Lyme who seem to do worse when attempting to alkalize their body. This happens because of the excess ammonia, therefore in order for these folks to be able to tolerate the alkalization procedure, they must first detox the ammonia. I know there are herbal formulas available for this purpose, not sure what they are or how they work....I think Dr. J in Kansas has one formula available, and probably Zhang's formulas contain stuff for dealing with the ammonia as well.
