the yeast spit test is a total scam!! you've posted this now on multiple forums.
we all have yeast in our bodies - it's completely natural. Usually sites trying to convince you that all your woes are due to yeast overgrowth in the gut are trying to sell you a product and they push the spit test to try to get you to buy their product. eat your veggies and get your whole grains and your body takes care of many things naturally. your bowels are the biggest organ in your entire body and it will make gas and have some bloating - that's normal!

Don't think it is accurate at all. Post in Ear, Nose and Throat. Yeast is not a STD.
