overall nutritional quality index overall nutritional quality index the overall nutritional quality index was a nutritional rating system developed at the yale-griffin prevention research center in 2008. a proprietary algorithm assigned foods a score between 1 and 100 intended to reflect the overall nutritional value a portion of the given food provided. the system was marketed commercially as nuval by nuval, llc, a joint venture with topco associates. over 1600 grocery stores in the united states placed nuval scores on product shelf tags next to the price. the commercial product was discontinued in 2017 amid accusations of conflicts of interest and criticism of nuval llc's refusal to publish the algorithm. either of which may have contributed to some inconsistencies in scoring where certain processed foods scored higher than, for instance, canned fruits and vegetables. description the algorithm considers thirty nutrient factors, like the relative portions of vitamins, sugar, saturated fat, and trans fats and the quality of the protein and fat, and produces a score from one to 100. higher scores represent greater overall nutritional value. however, the actual algorithm, including the relative weights of the nutrients, was never disclosed to the public. broccoli, blueberries, okra, oranges, and green beans were some foods that received the best score (100) while ice pops and soft drinks received the worst (1). selected nuval scores food nameonqi broccoli100 blueberries100 okra100 orange100 green beans100 pineapple99 radish99 summer squash98 apple96 green cabbage96 tomato96 clementine94 watermelon94 mango93 red onions93 fresh figs91 grapes91 banana91 milk (skimmed)91 avocado89 oatmeal88 atlantic salmon fillet87 atlantic halibut fillet82 catfish fillet82 cod fillet82 tilapia fillet82 oysters81 swordfish steak81 prawns75 shrimp75 clams71 monkfish fillet64 milk (whole)52 scallops51 turbot fillet51 pasta50 tinned peas49 turkey breast (skinless)48 prunes45 chicken breast (boneless)39 orange juice39 lobster36 pork tenderloin35 flank steak (beef)34 turkey breast31 veal chop31 veal leg cutlet31 beef tenderloin30 chicken drumstick30 pork chop (boneless centre cut)28 chicken wings28 lamb chops (loin)28 leg of lamb28 ham (whole)27 raisins26 green olives24 bagel23 peanut butter23 condensed cream of broccoli soup21 salted, dry-roasted peanuts21 fried egg18 swiss cheese17 diet fizzy drinks15 non-streaky bacon13 pretzel sticks11 dark chocolate10 white bread9 salami7 hot dog5 cheese puffs4 milk chocolate3 apple pie2 crackers2 fizzy drinks1 popsicle1
