<P> Beeturia is passing of red or pink urine after eating beetroots or foods colored with beetroot extract or beetroot pigments . The color is caused by the excretion of betalain (betacyanin) pigments such as betanin . The coloring is highly variable between individuals and between different occasions and can vary in intensity from invisible to strong . The pigment is sensitive to oxidative degradation under strongly acidic conditions . Therefore, the urine coloring depends on stomach acidity and dwell time as well as the presence of protecting substances such as oxalic acid . Beeturia is often associated with red or pink feces . </P> <P> The red color seen in beeturia is caused by the presence of unmetabolized betalain pigments such as betanin in beetroot passed through the body . The pigments are absorbed in the colon . Betalains are oxidation - sensitive redox indicators that are decolorized by hydrochloric acid, ferric ions, and colonic bacteria preparations . The gut flora plays a not yet evaluated role in the breakdown of the pigment . </P>
