I've been buying nutritional yeast flakes in bulk from my co-op for a while now. I mix it into olive-oil-and-herb-drenched pasta, sprinkle it on buttered toast, put it on rice and then put grilled veggies on top...all yummy!
Lately I've had a strong craving for nutritional yeast and have been eating it about twice a day, and not in small quantities; I'm eating probably 1/2 cup per day. I'm hoping to be pregnant
: and feeling encouraged that I don't have my usual PMS craving (salsa). However, I'm wondering if it's possible to eat too much nutritional yeast, and here's why:
Whenever I eat it, my urine turns a very bright slightly greenish yellow. When I first noticed this color, I attributed it to vitamins, because I'd just switched brands and have heard that vitamins sometimes turn urine green. But then I saw that it was intermittent (if it was from vitamins that I take daily, it would be consistent or go away as I got used to them, right?) and then I developed this craving and finally made the connection between the neon yellow urine and the bright yellow color of the yeast flakes! I tried resisting my craving for 36 hours, and sure enough, my urine returned to its normal color and then went neon again hours after I ate more yeast.
My question is: Is this a normal effect of nutritional yeast? If so, is it caused by the nutrients, or is there added coloring?
: (Because I buy in bulk, I don't have the ingredients list---I will look next time I go to the co-op, but that may not be for a little while.) Should I be concerned about this or try to see it as an artistic statement?
