My dad, who grew up in the depression and lived on a farm, said some people ate the bark off the trees (those not on a farm). He never saw a deer during the Depression—and still 3 million starved to death during this time.
During the Great Depression, many ate what was available.
In the corn regions, many developed a condition called corn poisoning. They ate so much corn, because it was plentiful for them, that they got sick from it.
My folks spent the Depression in Iowa where there was always plenty of vegetation to eat but meat was pretty scarce unless you had cash. My father hunted squirrel and rabbit.
The sainted FDR ordered pigs and cattle be killed to keep farm prices up not caring that in addition to killing livestock he was killing Americans.
Never let a crisis go to waste
