Nutritional Justice refers to the perverse phenomenon of unhealthy foods being cheaper than healthy foods, and the society-wide expense of the health consequences imposed on the economically challenged due to the diet our current food system makes most affordable.
These expenses include the personal health and well-being of individuals whose diets rely on "whatever meal is cheapest", lost productivity due to sickness, and increased Public health care costs related to diabetes and obesity for the very families who are the least likely to have private health care insurance.
More indirect economic costs are educational and behavioral difficulty due to poor nutrition, the effects of which can alter the course of a young person's life.
We have succeeded as a society at making food affordable to most of the population- but failed at making our people healthier. Ask your congressman to subsidize collards, not corn!
