"As a nutritarian, it’s important that you know the nutrient density of your food. Not merely vitamins and minerals, but adequate consumption of phytochemicals are essential for a normal immune system and to enable our body’s detoxification and cellular repair mechanisms that protect us from cancer and other diseases.
Nutritional science in the last twenty years has demonstrated that colorful plant foods contain a huge assortment of protective compounds, mostly unnamed at this point. Only by eating an assortment of natural foods that are nutrient-rich, can we access these compounds and protect ourselves from the common diseases that afflict Americans. Our modern, low-nutrient eating style leads to an overweight population with common diseases of nutritional ignorance and medical costs spiraling out of control. We need to flip our traditional thinking upside down, and begin eating a diet rich in vegetables, fruits, nuts, seeds, and grains, as illustrated in the Eat Right America Food Pyramid.
In order to measure nutrient density, Eat Right America created rankings of foods according the nutrients they pack. This concept is explained further in Dr. Fuhrman’s book Eat for Health.
Because phytochemicals are largely unnamed and unmeasured, these rankings underestimate the healthful properties of colorful natural plant foods compared to processed foods and animal products. One thing we do know is that the foods that contain the highest amount of known nutrients are the same foods that contain the most unknown nutrients too. So even though these rankings may not consider the phytochemical number sufficiently they are still a reasonable measurement of their content.
Keep in mind that nutrient density scoring is not the only factor that determines good health. For example, if we only ate foods with a high nutrient density score our diet would be too low in fat. So we have to pick some foods with lower nutrient density scores (but preferably the ones with the healthier fats) to include in our high nutrient diet. Additionally, if a thin person or highly physically active individual ate only the highest nutrient foods they would become so full from all of the fiber and nutrients that would keep them from meeting their caloric needs and they would eventually become too thin. This of course gives you a hint at the secret to permanent weight control.
Eat Right America's Nutrient Density Scoring System
To determine the scores above almost all vitamins and minerals were considered and added in. Nutrient Data from Nutritionist Pro software for an equal caloric amount of each food item was obtained. We included the following nutrients in the evaluation: Calcium, Carotenoids: Beta Carotene, Alpha Carotene, Lutein & Zeaxanthin, Lycopene, Fiber, Folate, Glucosinolates, Iron, Magnesium, Niacin, Selenium, Vitamin B1 (Thiamin) Vitamin B2 (Riboflavin), Vitamin B6, Vitamin B12, Vitamin C, Vitamin E, Zinc, plus ORAC score X 2 (Oxygen Radical Absorbance Capacity is a method of measuring the antioxidant or radical scavenging capacity of foods).

Nutrient quantities, which are normally in many different measurements (mg, mcg, IU) were converted to a percentage of their RDI so that a common value could be considered for each nutrient. Since there is currently no RDI for Carotenoids, Glucosinolates, or ORAC score, goals were established based on available research and current understanding of the benefits of these factors. (limited references below). The % RDI or Goal for each nutrient which the USDA publishes a value for was added together to give a total. All nutrients were weighted equally with a factor of one except for the foods ORAC score. The ORAC score was given a factor 2 (as if it were two nutrients) due to the importance of antioxidant nutrients so that measurement of unnamed anti-oxidant phytochemicals were represented in the scoring. The sum of the food’s total nutrient value was then multiplied by a fraction to make the highest number equal 1000 so that all foods could be considered on a numerical scale of 1 to 1000.
