Beets can turn urine or feces pink or crimson. However, this is not detrimental. Beets have been linked to low calcium levels and renal injury. For these reasons, people with impaired kidney function should not eat foods that are colored by beetroot juice. Those who are healthy enough to consume beets should not experience any negative effects from doing so. The color of the beetroots does not affect their quality or taste as far as we know. However, individuals who have an allergy or sensitivity to beta-carotene may experience symptoms after eating beets. Also, drinking beetroot juice may cause some people with certain conditions to lose weight even though they are not eating any more than before. In conclusion, consuming beets is safe for most people. However, those with impaired kidney function should avoid red beets because they may cause them to lose water and sodium. Otherwise, eat them in moderation.
