Strawberry toxicity?
Listen, I'm not saying they should be consumed en masse with every meal.
Something more like see a solar flare and have a strawberry party.
I doubt that whatever is in the berries is a miracle chemical or cocktail, its probably not that much more significant in the face of GCR than conventional anti-oxidants.
Conversely, just because NASA issues something in a pill doesn't mean it's good for you or even works. Ever hear of "scope-dex"? Having astronauts popping straw-placebios isn't going to solve anything.
