Welcome to Gaia! ::

Isn't vitamin A one of the ones that can be more easily overdosed on? Like, the excesses don't just run out when you take a leak ( like vitamin C, for instance ), but store up in your liver and fat instead, with the potential to reach toxic levels?

I'm pretty sure it's in that category of vitamins that, whereas deficiencies are bad, a surplus is dangerous.

Agreed, but a moderate level vitamin like A probably belongs in something other than a staple food like rice, wouldn't you think?

I figure the advantage was that it's rice, y'know? I mean, it's cheap and easy to grow, can be grown in large quantities in little time . . . and about the only things it really lacks naturally are vitamins A and C.

I'd still be leery of the possibility of accidental megadosing, but it seems to already be something of a wonderfood that with just a little bit of tweakage could probably do amazing things toward world nutrition while not cutting into crops raised for energy reasons.

Golden rice contains beta-carotene, a vitamin A precursor, and apparently the body only converts as much A as it needs from it, making overdosing impossible. Too much supplemental beta-carotene may cause problems for smokers, but I suspect that for those whom rice may be the only food available/affordable, tobacco is an unheard-of luxury.

They need to label all products with GMOs (or products that consumed GMOs) so consumers can make that decision for themselves. Maybe even go so far as to say which GMOs were used. Let the consumer decide if they want to eat it or not. Also publish all findings on research so people can make INFORMED decisions. I'd prefer that more research be done on them by outside sources not paid by the companies making the GMOs before they make their way to the consumer's table. And for longer periods than the companies tend to look at. I can't jump completely on the 'they're all bad' or 'they're fine' bandwagon without more data. And ones that are showing to be detrimental to consumer health need to be taken off the market. If there is a question to it, with data showing that more research needs to be done, that doesn't mean it's okay to keep them on the market until they get the all clear or the ax. They need to stop playing games with people's health and lives. Be certain it isn't adding to people's health problems. As I said, I'm not outright against them, but I want to know more about them.
