"Americans are not nutrient-deficient because of our depleted soil, as some nutritional-supplement proponents claim. Americans are nutrient-deficient because they do not eat a sufficient quantity of fresh produce. Over 90% of the calories consumed by Americans come from refined foods or animal products...Since more than 40% of the calories in the American diet are derived from sugar or refined grains, both of which are nutrient-depleted, Americans are severely malnourished."
