What nutrients are missing from commercially grown food?
There is no general answer to this question. Some foods are
heavily refined, which removes nutrients from them. Some examples
are flours, breads made from refined flour, white sugar, white
rice, etc. Other foods may have been grown in soil which does not
contain all the nutrients and macro-nutrients, so those foods would
be lacking in nutrients. It really depends on how much processing
has been done on the food, whether high heat has been used on it,
the soil it was grown in, etc.
