Many doctors pooh-pooh the need to pay attention to the acidity of your diet. And they are right in that what you eat is not going to effect the pH level of your bloodstream. However, what they don’t tell you is that there are no magic elves buffering all of that acid.
The fact is that your body expends nutrients to maintain that rigid pH range. In fact, if need be, calcium will be pulled out of your bones and teeth to help buffer the acid. And guess what? Calcium is a neurotransmitter, so if it is diverted to buffer acid, your brain and nervous system may malfunction.
The the importance of avoiding an excessively acidic diet is easy to prove. If you are a skeptic, just try eating a super acidic diet for a few days and see what happens to you. Black coffee, doughnuts, Coca-Cola, pizza, etc. Then when you are wracked with pain, take a little calcium carbonate to experience the “miracle” cure that I wrote about here.
