Always a red flag if "potential benefits" cover a broad spectrum of unrelated symptoms: depression, cancer prevention, cognitive ability, heart health, diabetes, digestive health, even wound healing. A dodgy article at best.
Generally agree. One thing to note here is that this isn't a single chemical that we're talking about. It's certainly plausible that there are several different potential benefits in a food containing hundreds of chemicals. It still needs more research in this case.
