Step 1: Each nutrient value is divided by the daily value to yield a fraction. The fraction was capped at 1.

Step 2: The grams consumed are divided by the grams per RACC to yield a fraction of RACC consumed.

Step 3: The kcal consumed are divided by 100 to yield a fraction of 100 kcal portions consumed.

Step 4: Sum each column of calculated values from Steps 1-3.

Using the example in TableC-1, the calculated values from Steps 1-3 and sums from Step 4 are shown in TableC-2.

Step 5: Add the sums of the positive nutrients, multiply by 100, divide by the sum of the kcal/100, and divide by 8.

(0.72 + 0.68 + 0.17 + 0.51 + 0.73 + 1.17 + 0.47 + 0.46 + 0.46) * 100 / 14.52 / 8 = 4.22

Step 6: Add the sums of the negative nutrients, multiply by 100, divide by the sum of the kcal/100, and divide by 3.

(0.46 + 0.71 + 1.70) * 100 / 14.52 / 3 = 6.59

Step 7: Subtract the value from Step 5 − Step 6 to yield the individual's score based on 100 kcal.

4.22 − 6.59 = −2.37

To calculate the individual's score based on RACC, the sum of the grams/RACC column replaces the sum of the kcal/100 in steps 5 and 6. For the above example, the individual's score based on RACC is −3.28.
