I have to disagree with several of the comments here.
Our blood pH is changing all the time.
Being prone to kidney stones since I was a kid, I have my blood PH monitored and measured twice a year and I check my urine at least monthly and more often if I feel discomfort that could be caused by a moving kidney stone. Calcium-Oxalate stones are formed from “Bone Detritus” (small pieces of bone which break off/dissolve from our bones. It happens to everyone, much more as we age, if we do not eat in such a way to balance out that PH.
What foods cause lower PH (higher acidity)?
Carbonated Drinks, Excess Protein, Cereals, Sugars, Tobacco, Coffee, Tea, and Alcohol, and in general, most processed foods.
As we digress from “Whole Foods” in the form of natural vegetables our blood becomes more acidic. In essence we are similar to a battery and we determine the electrolyte composition by what we put in it.
As blood changes to more acidic, bone becomes more vulnerable to leaching of the calcium in it. Although I have never related it to tooth enamel, it makes sense that a lower ph from ingested foods would affect saliva since urine shows up more acidic quite quickly after consuming soft drinks with fizz (phosphoric acid). The blood follows more slowly.
I am not condoning any of the hype around Metabolic Typing Diets although there seems to be some science to it. At first impression, The Atkins diet definitely lowers pH, (more acidic). I know that eating meat protein with little else lowers pH since I can measure it with a Chem-Stik, later in the day or the next morning. Protein will be up, pH down and little else changes.
An easy and natural way to keep a balanced PH is with more leafy greens and wise carb choices in how we meet our ECC throughout the day. Spinach, Chard, and so on raise pH quickly. Drinking adequate water helps as well and serves to promote better health and definitely reduces the acidity of mouth saliva immediately.
One thing I found surprising was that the food pH itself is quite different from the pH affect is has on the body. Citrus fruits which are acidic, do not raise pH, but instead lower it after being digested.
If you check out the effects of lower pH at

Does this mean that LC/Higher Protein diets are to be discouraged?
Definitely not! Staying closer to whole foods, choosing LC fruits and veggies to fill your carb limit will do more than keep your pH where it should be. It rounds out most programs with essential nutrients in many positive ways.
