Asparagus is very beneficial food for our bodies. It is good source of fiber, folic acid, vitamin A, C, E and K as well as iron. And many studies have revealed that it is known for anti-cancer effects, prevention of heart disease, and cognitive enhancement.
Many studies have been done in terms of “asparagus urine” among decades. “Asparagus urine” was controvertible idea that some people feel excreted odorous urine after eating asparagus. That’s because 1) individuals digest asparagus differently or 2) some people could feel asparagus odor from everyone who eating asparagus.
Lorelei Mucci group in Harvard school of Public health have conducted large group of study that 40% of the people who participating in the experiment could feel “Asparagus urine”, whereas 60% of participants could not in their urine.
They analyzed over 900,000 genes to find out mechanism for Asparagus urine in our body, and found that 871 of them have mutations where located in Chromosome 1 including olfactory receptor 2 gene family.
Dr. Lorelei Mucci pointed out that it is not good and bad issue to smell the asparagus, and a follow-up study need to be conducted to elucidate how more than 60% of the participant groups can’t feel “Asparagus urine”. This will help to understand people who suffer from anosmia, loss of the sense of smell as well as therapeutic target for those people.
