Well, I posted a video of Mat Lalonde’s presentation on Nutrient Density (AHS 12) just the other day. I originally intended to follow up with a copy of his research (with permission). When I asked for the data, however, Mat surprised me with this response:
I put the data through a stress test and found some inconsistencies. It turns out that there was too much variance in the data to use a standardization method. As such, I completely revamped my approach and divided the nutrient data by the RDA in order to make the values unitless and bring them within similar orders of magnitude. I’m now working on getting the data published and cannot share the spreadsheet until this is done.
