So, do I keep eating my blueberries?
Eat all you want. Just be careful of the side effects.
I have heard that high doses of antioxidants can screw up the actions of some antibiotics. I think those antibiotics work by oxidizing action on the bacteria, so all those antioxidant fruits you eat to keep you healthy also keep your bacteria healthy.
Yeah, sure, you're not using those muscles anyway. ;-)
Not sure if they're talking about small amounts occurring naturally. I think they mean additives but that's just a guess.
Long as you can reach them, I guess.
