When antioxidants were taken in higher doses in the form of supplements they were harmful.
Quite possibly true, maybe there is something other than antioxidative effects at work, and the hormesis hypothesis is certainly interesting. However, the fact that antioxidant supplements do not have beneficial effects and are sometimes even harmful does not disprove the hypothesis that antioxidants in their natural form can be effective/beneficial.

Aarrghh, don't take my excuses from me!! Now I have to go find new ones!

That would make a nice headline in the Daily Mail (or whatever UK tabloid postures as the Nation's health expert")

. Arguing like that, is there any food that is not poison? The "poisonousness" of poison depends on the dosage. The process of living in itself is lethal.

Couldn't agree more - but you've got to hand it to them, the term sounds annoyingly catchy.
