alkaline & acidity ?

So lemon waters ph is below 7 because it's acidic. Our body changes to produce less acid because if this, correct?

So distilled water is also acidic with a ph below 7. However it's been said that this makes the body a more acidic state, am I correct?

Otherwise wouldn't distilled water be good for detox, what makes it different than lemon water?

So would lemon distilled water be good for detox, if the alkaline lemon cancels out the acidic distilled water.
