Although it is somewhat of a myth that eating too many blueberries can turn your urine blue, the fact is that the color it produces in urine is red.

There are a number of foods and drinks that can turn urine red, such as colored cereals, kool-aid, boysenberries, chocolate laxatives, and beets. Red urine can also be a sign of lead poisoning, though it is much more commonly caused by the consumption of certain foods and drinks such as the ones listed above.

In order for your urine to turn red, you will have to consume a considerable amount of blueberries.
