Studies indicate that about 79% of Americans are "excreters" -- they excrete smelly sulfur compounds in their urine -- as are about half the people in Britain. Non-excreters don't suffer asparagus-eating's effect on urine odor because they don't produce these sulfur compounds. The ability to "excrete" is inherited.
I've heard that as well ... that everyone excretes, but only some can smell it.You know they did a study in the 80s that I am reading about that it actually isn't whether you excrete it or not, but whether or not you can smell it. So according to their study, everyone does it, but can't smell it.
So, is "excreting" then considered a good thing or a bad thing? or does it matter? Because I just had some asparagus this week, and I didn't notice anything... different.
