we don't know all that much about nutrition. a little birdie once told me that it was impossible to meet nutrition requirements while staying within the calorie intake guidelines without taking suppliments.

i say... so much worse for the 'nutrition requirements'.

there are a lot of different guidelines for your RDI of various things. there is controversy basically.

but surely people were healthy before suppliments were invented!

though that being said availability of food can be tricky...

in some places of third world countries to be sure...

and in some places of developed western nations as well...
