Re: quality of foods is the key


"The nutrient density in various food groups for the 13 vitamins and
minerals most frequently lacking in the US diet are contrasted in Table

4 (64, 143, 144). Because whole grains and milk maintain the next to
the lowest nutrient density rankings, displacement of fruit,
vegetables, lean meats, and seafood by these 2 staple food groups
lowers the overall micronutrient density in the diet. Wild plant foods
known to be consumed by hunter-gatherers generally maintain higher
micronutrient concentrations than do their domesticated counterparts
(4, 145), as does the muscle meat of wild animals (64). Consequently,
the Neolithic introduction of dairy foods and cereal grains as staples
would have caused the average micronutrient content of the diet to
decline. This situation worsened as cereal milling techniques developed

in the Industrial era allowed for the production of bread flour devoid
of the more nutrient-dense bran and germ (35). The displacement of more

nutrient-dense foods (eg, fruit, vegetables, lean meats, and seafood)
by less-dense foods (refined sugars, grains, vegetable oils, and dairy
products) and the subsequent decline in dietary vitamin and mineral
density has far reaching health implications-consequences that not
only promote the development of vitamin- deficiency diseases but also
numerous infectious and chronic diseases (7). "
