My friend, that is a first :) I honestly have never heard of such a thing. It could be the sprouts, but im not too sure. My guess would be that the contents of the sprouts is being expelled through your sweat making your skin smell like marsala? I know it sounds ridiculous but that is the best explanation that I could come up with. By the way, what is the amount of sprouts that go into that smoothie of yours??
Bingo! It’s the fenugreek that’s leaving your skin smelling like masala. Here’s an excerpt from wiki A side effect of consuming even small amounts of fenugreek (even as just an infusion in water) is a maple syrup or curry smell in the eater’s sweat and urine, which is caused by the potent aroma compound sotolone.
I hope this isn't offensive to anyone (if so I apologize in advance), but when I learned about raw in mid 2000 I didn't know anything so all I ate was salad w/ lemon juice and lots and lots of bananas and oranges for six weeks. Lots of oranges, and after the first 2-3 weeks my "area" and my sweat (sorry, but this is true) smelled like orange. Towards the end I'd been craving onions and had been eating them like as if they were apples and I smelled like onion BUT not in a bad way...it actually smelled good.
My ex still remembers this and can vouch for it.
I know it's weird, but it happened.
