Generally, no significant side effects are associated with consuming beet flow as part of a balanced diet. However, some people may experience mild gastrointestinal discomfort when they increase their intake of beets or beet products. If you have a history of kidney stones or are prone to oxalate-containing kidney stones, you should consume beets in moderation as they are a source of oxalates. Always consult a healthcare professional or nutritionist if you have specific dietary considerations.
