For 2 days I ate nothing but alkaline foods. Lots of RAW fruits and vegetables along with things like olive oil, blackstrap mollasses and apple cider vinegar. I tested my PH throughout the day, 2hrs after eating, right after eating, multiple times. The highest I ever reached was a mild green color which was about 6.3.
Today I woke up with it light green/really low PH. Guess what made it turn to a dark green? Lindt Chocolate Truffles. 6.8. Yeah, that makes sense.
I then went around testing my animals. lol
Dog (100% raw meat diet)- Light Blue
Cat (100% raw meat diet) - Dark Blue
My gerbil whose diet consists of too many acidic nuts/seeds/grains (lacking in greens) also came out a dark blue color. That one suprised me. I don't know what my animals' PH should be but it still makes me wonder.
