My sister's post about a yummy beet recipe made be think of something that happened to Dan and me a few weeks ago. I'd bought some beets at the local farmer's market, boiled them and served them with just a bit of butter and salt and pepper. We like them but these beets were exceptionally red and that next morning I was startled by the color of my urine but then remembered the beets. When I'd asked him if he experienced this phenomenon he was quite relieved to find out it was only the beets.
The following is an explanation from a great website called World's healthiest Foods
If you start to see red when you increase your consumption of beets, don't be alarmed. You're just experiencing beeturia, or a red or pink color to your urine or stool. No need to panic; the condition is harmless.
