However, this has not been demonstrated in individuals. Further, the relationship between beet consumption and calcium levels is unclear. Beets are a root vegetable that belongs to the family Amaranthaceae. The beets we eat come in many varieties, but they all contain high amounts of fiber, vitamin C, potassium, and folic acid. They're also very affordable! There are two main types of beets: red beets and white beets. Red beets have a thick skin which should be removed before eating them. This skin contains nutrients such as anthocyanins, which give beets their color. Eating the beet itself will produce a blue color in your urine that lasts for several hours after swallowing. The human body can process beet juice differently depending on the color. Research shows that urine produced from drinking red beet juice will remain blue after being held at room temperature for more than an hour. However, urine produced from drinking white beet juice will disappear from being blue within 30 minutes at room temperature. Because beets can increase the amount of cyanide in your system, anyone with a history of heart problems should avoid consuming them.
