Well, Barry was only taking 500 mg C (which is what is in most multivitamins) and they told him to stop, also 200 mg gamma-E (not a-tocopherol which is what is in Boost). Most other liquid diets are also rather heavily vitamin-enriched, something to keep in mind if you are also taking a multi-vitamin (which Barry was not, as not recommended by his prostate oncologist).

If he ends up using 6 cans of Boost Plus/day, he will be back to ingesting about 500 mg C or 6X the RDA. (And we know the Boost C is not naturally occuring as it would be in, say, orange juice.) Also a lot more beta-carotene (150% of daily value), than would seem prudent, at least for patients that were smokers.

This is not to dump on Boost but I do detect a certain inconsistency here...

This whole issue is controversial, have recently seen a number of papers and a couple review articles that dismissed the "conventional wisdom," finding more evidence for beneficial than negative effects from reasonable intake of certain antioxidants during radiation (not mega-doses).

I think the jury is still out on this...
