Organic foods vs. supermarket foods: Element levels

Over a 2 yr period, organically and conventionally grown apples, potatoes,
pears, wheat, and sweet corn were purchased in the western suburbs of
Chicago and analyzed for mineral content. Four to 15 samples were taken
for each food group. On a per-weight basis, average levels of essential
minerals were much higher in the organically grown than in the
conventionally grown food. The organically grown food averaged 63% higher
in calcium, 78% higher in chromium, 73% higher in iron, 118% higher in
magnesium, 178% higher in molybdenum, 91% higher in phosphorus, 125% higher
in potassium and 60% higher in zinc. The organically raised food averaged
29% lower in mercury than the conventionally raised food.
