No...I read about it and figured that eating more vegetables wouldn't be harmful so I gave it a try. I tend to be a very practical person. I'll try it as long as I see no harm in it and if it works it works, if it doesn't I'll try something else. I use pH strips to check urine and saliva. You really don't want the pH of your blood to change. More importantly I can tell by the way I feel. When my diet is good I feel better and no shortness of breath.
