Yale nutritionist proposes “healthy food” scale based on nutrient density

The simple idea of the Overall Nutritional Quality Index (ONQI) is this: the higher the score given to a foodstuff, the more nutritious it is. So, broccoli scores the highest, at 100 (as do blueberries, oranges and green beans) while ice pops and fizzy drinks get only one point. Foodstuffs score high for dense amounts of nutrients such as vitamins and protein, but lose marks if they also contain baddies including added sugar, salt, saturated or trans fats. So far, three supermarket chains in the US have adopted ONQI, with another 15 to 20 companies planning to get involved next year. It may eventually be used in up to 7,000 stores across the country.
