Most of them come from food, drinks, drugs, cosmetics and the environment

After spending as many as 7 years researching the chemical makeup of human urine, scientists have reached the conclusion that this fluid contains at least 3,079 different compounds that belong to 230 classes.

As was to be expected, most of these compounds (2,282 to be more precise) come from the food we eat, the drinks we gulp down, the cosmetics we use, the drugs we take and the environment we live in.

According to Live Science, an impressive 1,453 compounds are produced by the body itself during various metabolic processes. The remainder 72 come from bacteria.

By the looks of it, this means that urine contains about 5 to 10 times more compounds than all the other fluids in our bodies. Who knew, right?

“Urine is an incredibly complex biofluid. We had no idea there could be so many different compounds going into our toilets,” researcher David Wishart commented on these findings.
