is it possible that the guidelines were setup when people did weigh less due to less food, less nutrient rich foods and worked physically/agrarian society?

my parents (depression era kids) said they never had enough food to eat and most of their friends did not either and they were more underweight. they had no access to vitamins or minerals or nutrients.

see - i can rationalize anything -HAH! we are not supposed to conform to insurance co charts that were setup many years ago.
