I did some googling and reading on this subject. All the articles I found that advocate worrying about your body's PH balance also contain claims that don't make much sense to me. Many of them claim that all disease has the same cause - acidosis. From what I understand of human biology, this is a ridiculous claim.
I read some articles arguing against the whole body PH thing, and they made some points that make a lot more sense to me:
- The body stays within strict limits when it comes to PH balance. If your body became acidic, as some claim it can, you would be extremely sick and probably even close to death.
- The stomach is highly acidic. Whatever you eat becomes acidic in your stomach. When food leaves your stomach, secretions from your pancreas make it alkaline. So it's always acidic in your stomach and always alkaine in your intestines.
- Some foods do leave behind ash which can be acidic or alkaline, but the only thing that affects is your urine. Urine is the only bodily fluid with a PH that can be changed by what you eat.
- One of the ways that the body regulates its PH is by using calcium from your bones (the pro bidy PH articles said this too). A diet that includes a good amount of calcium should be enough to ensure that you don't become calcium deficient due to the body's self-regulating.
http://www.drmirkin.com/nutrition/1603.htmlIt makes sense to me that drinking lemon water is beneficial, but not because of anything to do with PH. Fresh fruit is generally packed with vitamins and good for you. On top of that, if you are replacing sugary, calorie-packed drinks (even 100% fruit juices can have a lot of sugar) with lemon water, you're doing extra good for yourself.

in a few months with very little to no exercise(I walk alot, cut out most cheeses, low to no soda- but lets keep it real-
i drank so much I peed the bed one night! had a dream i was on the toilet and woke up like 
got here. I actually went back to vegan for a month. It kindah helps my body....hmmm how can I put this...'regulate'. I'm not a heavy meat eater anyways and red meat is not in my diet. I have trouble processing that ish. Anyways, back to the lemon....I normally keep fresh lemons. Keep some for cooking, cleaning, hand washing(definitely hand washing.) Lemon water works wonders. Just don't go overboard like Sam.
