Here’s a balanced article that talks about the health benefits and some potential downsides. As with many things, to key to getting the best benefits is to exercise moderation, and certainly to avoid orange juice with artificially added sugar.
ETA: The bottled orange juice I buy is President’s Choice, a premium store brand that’s a bit better than most commercial brands. I just checked the label and it says “Ingredients: Orange juice”. However, it does carry a health label warning about high (natural) sugar. So, as I said, moderation!
