Do personal lubricants containing glycerin increase the chance of a yeast infection?
The all-knowing oracle Google returns mixed easy answers:
Yes, it does...
No, it doesn't...
At this point, the smart thing to do is look for higher quality sources of information. Information literacy, etc. But why do that when I have such a good excuse to run an experiment in my kitchen?
I set out two empty measuring cups and put "Sugar" and "Glycerin" paper labels next to them. In a separate glass, I prepared 112° Fahrenheit water. (From my yogurt making, I know this is a prime yeast-growing temperature.) I then poured half a cup of warm water into each measuring cup.
In the "Sugar" cup, I stirred in one tablespoon of sugar. In the "Glycerin" cup, I stirred in one tablespoon of glycerin:
|Ingredients: Glycerin 99.5% Anhydrous|
Then, I stirred one teaspoon of active dry yeast into each cup. Utensils were kept separate throughout this process, of course. I soon saw clear results.
Horrifying if you think about the context of this post.
The yeast is confused about why someone put it in warm water with nothing to eat.
Not all that tastes sweet is a yeast-infection inducing sugar. People are easily swayed by superstition. Kitchen science isn't as robust as journal science, so treat this like you would MythBusters.
