Claim 2
That flesh foods are necessary for blood building, especially red meats, because of their iron content.
This claim is wholly without scientific support. Modern experiments have shown that anemic animals recover most quickly on a diet rich in plant iron. Green foods have been proven to be sources of the best iron, which is associated with chlorophyl.
The iron of meat has been once used and is of the same sort as that which the body throws away. It is inferior to the iron of green plants, from which the ox makes his red blood.
Nuts contain a rich store of this precious plant iron, as do also beans.
