For the purposes of CR, the important value is ORAC/calorie - i.e.

how do we get the most antioxidant bang for the calorie buck in what

we eat?

There are a number of places on the web where the ORAC data (as ORAC

per 100g or 3.5 oz) is presented.

http://www.preventionline.com/z3_newsviews.asp?ID=26 - I have no

idea where this one got the calorie count for blueberries.

http://www.ars.usda.gov/is/np/fnrb/fnrb499.htm

I've uploaded the following data to our files area as

Orac per calorie.xls

/files/ORAC%20per%

20calorie.xls

I've taken the ORAC data, and the calorie counts for 100g of the raw

fruits and veggies (from the USDA Database), and calculated the

following as ORAC/calorie:

Prunes 23

Raisins 9

Blueberries 43

Blackberries 39

Strawberries 51

Raspberries 25

Plums 17

Ornages 16

Red Grapes 11

Cherries 9

Kiwi 10

Pink Grapefruit 16

Kale 35

Spinach 57

Brussel Sprouts 23

Alfalfa Sprouts 32

Broccoli Flowers32

Beets 20

Red Bell Pepper 26

Onion 12

Corn 5

Eggplant 15

This indicates that strawberries (yum!) and spinach (also yum! - and

I'm not getting embroiled in the oxalic acid arguments here) are the

best values, i.e. fewest calories per equivalent ORAC. Blueberries

aren't too shabby either, but not the best. Prunes and raisins lose

out because of their high calorie values.

Now, to get the best ORAC/$, you'd need to take the current cost of

each of the above, per 100g and ..... " This proof is left to the

student. "
