Nutrient Scoring Method
To determine the ANDI scores, an equal-calorie serving of each food was evaluated. The following nutrients were included in the evaluation: fiber, calcium, iron, magnesium, phosphorus, potassium, zinc, copper, manganese, selenium, vitamin A, beta carotene, alpha carotene, lycopene, lutein and zeaxanthin, vitamin E, vitamin C, thiamin, riboflavin, niacin, pantothenic acid, vitamin B6, folate, vitamin B12, choline, vitamin K, phytosterols, glucosinolates, angiogenesis inhibitors, organosulfides, aromatase inhibitors, resistant starch, resveratrol plus ORAC score. ORAC (Oxygen Radical Absorbance Capacity) is a measure of the antioxidant or radical scavenging capacity of a food. For consistency, nutrient quantities were converted from their typical measurement conventions (mg, mcg, IU) to a percentage of their Dietary Reference Intake (DRI). For nutrients that have no DRI, goals were established based on available research and current understanding of the benefits of these factors. To make it easier to compare foods, the raw point totals were converted (multiplied by the same number) so that the highest ranking foods (leafy green vegetables) received a score of 1000, and the other foods received lower scores accordingly.
