Many nutrition experts praise beets for their rich color and impressive nutrient profile, but doctors warn that they are not ideal for everyone. Beets are high in natural nitrates, fiber, and antioxidants, which can support heart health and circulation. However, in some cases, eating beets may cause unwanted effects. For people prone to kidney stones, beets can be problematic because they contain oxalates—compounds that may contribute to stone formation in susceptible individuals. Those with low blood pressure should also be cautious, as the nitrates in beets can further lower blood pressure, potentially causing dizziness or lightheadedness. Additionally, beets are relatively high in natural sugars, so individuals managing diabetes should monitor portion sizes carefully.

Doctors also note that some people may experience digestive discomfort after eating beets, especially if consumed in large quantities. Bloating, gas, or changes in stool color—such as reddish or pink urine (a harmless condition called beeturia)—can be surprising and concerning if unexpected. People with certain digestive disorders, such as irritable bowel syndrome (IBS), may find that beets trigger symptoms due to their fermentable carbohydrates. While beets remain a nutritious vegetable for many, moderation is key. Understanding your individual health conditions and consulting a healthcare professional when necessary can help determine whether beets are a beneficial addition to your diet—or something to limit for your well-being.
