Is your urine red? You may have just eaten this vegetable | Dr. Itay Gal
Beets are a healthy vegetable rich in pigments, but for some people, they can turn urine or stool red. This phenomenon is called beeturia, and it is usually not dangerous. It is important to know when you can relax and when you must get checked.
The red that causes stress: There are moments when the body manages to scare even particularly calm people. One of them is looking into the toilet and discovering that the color of the urine has turned pink or red. The first thought is usually blood. But if beets appeared in the previous meal, the explanation may be much simpler.
The pigments that give beets their intense color are called betalains, and the most prominent of them is betanin. In some people, the pigment does not break down completely in the digestive system, is absorbed, or passes through the intestine and is excreted in the urine or stool. The result can be a dramatic color change, sometimes hours after eating and sometimes the next day.
Beeturia is generally considered a benign phenomenon. It does not in itself indicate damage to the kidneys, liver, or bladder. The exact prevalence varies between studies and populations, but it is a known phenomenon. It can appear more when stomach acidity is lower, when eating a large amount of beets, or when there are changes in absorption and transit in the intestine.
But here one must be careful not to make excessive assumptions. Not every red urine is beets. Blood in the urine can be caused by a urinary tract infection, kidney stones, kidney diseases, trauma, strenuous physical activity, certain medications, and in rare cases, tumors. Therefore, if the red color appears without a clear connection to eating beets, recurs again and again, is accompanied by pain, burning, fever, or blood clots, one should seek an examination.
One should also exercise judgment with red stool. Beets can color the stool dark red or purple, but bleeding from the digestive system can look similar. If there are severe abdominal pains, weakness, dizziness, black stool, fresh blood in a significant amount, weight loss, or a change in bowel habits, one does not automatically attribute this to beets.
A simple way to check for a connection is to ask what was eaten in the last 24 to 48 hours. If beets were there, there are no other symptoms, and the color disappears quickly, it is likely a nutritional phenomenon. If the color persists, worsens, or appears without beets, there is a place for a urine test or medical investigation.
Beets themselves are a nutritious vegetable. They contain fiber, folic acid, potassium, and natural nitrates that have been studied in the context of blood vessels and blood pressure. They can fit well into salads, soups, and stews. People with a tendency to calcium oxalate kidney stones should remember that beets also contain oxalates, so in some cases, individual nutritional advice will be required.
Some people experience both a change in urine color and softer stools after beets. Usually, this is not a problem. But as always, dosage matters. Eating a very large amount of beets or drinking concentrated beet juice can cause discomfort in the digestive system, especially in those who are sensitive to fiber or certain sugars.
In children, the phenomenon can be especially alarming for parents. If a child ate beets at kindergarten or at home and the urine is pinkish, and they feel well, without fever, pain, or burning, one can monitor. If there are symptoms of a urinary tract infection, abdominal pain, vomiting, or blood that seems to persist beyond a reasonable time, one should contact a pediatrician.
Beets are not dangerous because of their color. On the contrary, the color is part of their nutritional richness. But they teach an important lesson: sometimes food changes what we see in the toilet, and sometimes the body is really signaling a problem. The difference lies in the context, the symptoms, and the question of whether the color disappears when beets are removed from the menu.
