>1) berries -- dog rose, crow berry, wild blueberry 39.46 - 8.23

>7) legumes & pulses -- fava beans, pinto beans .... 1.86 - 1.14

>8) grains and cereals -- barley, millet, oats ..... 1.09 - 0.59

>Legumes and Grains had the poorest total anti-oxidant power.

>Berries, nuts, seeds, and fruits had the best total anti-oxidant power.

>Walnuts were a particular high-ranking surprise.

>The highest top dozen ranking foods, all with FRAP anti-oxidant power

>greater than 5.00 mmol/100g were in the following order:

># 1) dog rose

># 2) walnuts

># 6) blackberry

># 7) sour cherry

># 8) wild blackberry

># 9) wild strawberry

>#10) sunflower seed

>#11) cultivated blackberry

>#12) cowberry/cranberry.
