Keep in mind that analytical methods change over time, and small changes in
method can affect results. Methods today are easier and more accurate than
in the 40's. Making comparisons across large expanses of time or space is
always unreliable. For example, just letting the vegetables wilt before
testing would increase mineral content by weight (by reducing water
content). Studies that use a local control (more-or-less side-by-side
production) are far more reliable, and should always over-rule results like
those presented by Rodale. Those folks at Rodale should know better.
