I love beetroot but have never had any sign of it in my urine so I must have an acidic stomach!
Beeturia (Pink Pee)
Be aware that ingestion of beetroot can colour urine red and also discolour stools, causing the unwary to hot-foot it to their GP for urgent tests. The pinkness of your pee depends on the acidity of your stomach; some people don't see pink pee afterwards and some do (approximately 10 - 14%). If you don't see pink pee then your stomach is at the strongly acidic end of the normal range - if you do see pink pee then your stomach is at the less acidic end of normal, and the colour hasn't been broken down on the way through your gut.
"Beeturia is a harmless occurrence and you do not have to exclude beetroot from your diet if you are affected by it. If you don't normally have pink-stained pee after consuming beetroot, you might like to try an experiment. Try taking some antacid1 tablets, then eat beetroot. Remember to look at what you're doing the next time you visit the toilet. That should satisfy your curiosity.
If your urine is coloured pink or red and you haven't ingested any beetroot, this is called haematuria and requires medical investigation to find out the cause."
