What we eat in America (Vitamin D is the nutrient we get the least of)

This is taken from US: 2015 Dietary Guidelines Advisory Committee submits report
Vitamin D is mentioned about 200 times in the submitted report - asking for comments
The massive report is too big(11 MBytes) to have on VitaminDWiki
The proposed guidelines say that we need more vitamin D, but does not seem to say how much more nor how it can be accomplished.
