2- BOOSTED NUTRIENT DENSITY Nutrient density, functionally, describes higher levels of nutrients and beneficial secondary plant metabolites per unit of volume. Nutrient dense food is virtually the opposite of ‘empty calories’. One well cited study by Donald Davis found that the average nutrient content of most vegetables and fruits have declined dramatically over the past 50–70 years. As the Bionutrient Food Association states, “The problem is, we now live in a world where natural foods, can be nutrient poor. Even organic and local foods can be low in nutrition, depending on the growing practices, season and seed.”
