At least nobody seem to agree with the author of the book in thinking that the Jamestown
colonists died becauise of a deficiency disease. On another thread here I learned that Mexicans
and other South Americans enhance nutrive value of corn by treatment with alkali in small amounts.
I wonder how they learned the value of this, because it takes so long for the benefits to become
apparent. Look how long it took for Europeans to learn how to avoid scurvy.
