It's impossible to change your body's pH by consuming baking soda. All that will do is to cause your body to produce more stomach acid in order to compensate for the higher alkaline solution. Your body requires that low pH in your stomach in order to be able to digest anything.
Blood pH is about 7.4
Stomach pH is about 2.5
Urine should about 5.5
Taking baking soda in order to raise your pH is similar to the alkaline water myth.
A shorter vid that you might find interesting Bob. Note at the end the part about heart issues.
I thought when you mixed baking soda and vinegar you got a fizzy mess.......IIRC, thats the concoction I used to make a volcano spew at the 3rd grade science fair. if anyone does a spoon of baking soda, and chases it w ACV, please get a vid of the occasion, and post it up here. I bet the whole thing looks like that time I did too many keg-stands in college.
