Guest guest Posted February 4, 2003 Report Share Posted February 4, 2003 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.
