Subject: Does agricultural produce contain the same nutritional value as it used to?

Since minerals must come from the soil to get into the plants we eat
we are constantly replanting crops each year without
replenishing the soil's minerals - is a potato, for exaamole,
grown today as nutritious as a potato grown
200 years ago?  We read more and more about these issues
that Americans are not getting the nutrition they require, 
not because of their diet, but because the food
products themselve grown from the earth are
rapidly losing their nutritional values.
