And this... If the lemon or lime is of high enough quality to contain adequate levels of calcium.
How do you get a water pH of 8? Well, the simplest thing to do is squeeze some fresh lemon or limejuice into it. Most people think that doesn't make sense because it is an acid fruit, which would make you more acidic. But that does not occur because lemon and lime have a lot of calcium, which converts to calcium hydroxide in the body and that raises your body pH (increases the alkalinity).
