Prune juice caused black bowel movement?

Hi all

Today I had a almost black bowel movement, looking at my diet, I've been drinking prune juice in the morning for the past week. Last time I drank some was Saturday, could this cause the black bowel movement?

Pretty sure you've answered your own question ;)

Yes. Watch out if you ever eat beetroot too.
