so I wonder what happens if I dont get my recommended intake of e.g. Vitamine A? I guess I don’t need it *really* daily and the recommendation are more of a guideline regarding a average you should get in a week. But maybe I am wrong? Can I eat something with a lot of Vitamine A and skip some days? How many days until it becomes a problem? What with the other stuff?
And also how did scientists get these measurements? Did they withheld rats selected nutrients and watched how long till they died and then scaled those nutrients to human levels or something like that?
