Building our bodies with nutrients is why we eat, and not all food is created equal. Even organic, local food can still have a wide range of nutritional value depending on the quality of the soil the food is grown in. The islands study in 2015 compared the nutrient content of the beans grown in the study to dry beans purchased at a QFC in Seattle. The study found an increase of micro nutrients in the locally grown beans with charcoal as opposed to the control. And the QFC beans, they came in last.
Don't we all want food with more in it?
