Like anything involving "density," " nutrient density" means how much you get of one thing, given the presence of something else. In the case of nutrient density, the "things" you receive, the nutrients, are analyzed in relationship to how much they "cost" you, in terms of calories. Simply stated, nutrient density means how many nutrients you get from a food, given the number of calories it contains. Nutrient density is a simple way to connect nutrients with calories.
Nutrient dense foods give you the most nutrients for the fewest amount of calories. In other words, nutrient dense foods give you the "biggest bang for the buck." You get lots of nutrients, and it doesn't cost you much in terms of calories.
Nutrient density is the exact principle we used when we rated all of 127 foods found on the World's Healthiest Foods website. The World's Healthiest Foods give you the biggest bang for your buck. They give you the most nutrients possible for the least amount of calories.
Eating nutrient dense foods like the World's Healthiest Foods is one of the healthiest ways that anyone can eat. No principle is more likely to support healthy eating than the principle of nutrient density. Why is nutrient density so helpful? Because it gives you concentrated amount of valuable nutrients such as vitamins, minerals, fiber, essential fatty acids and phytonutrients, to name a few.
Let's take a quick example. Let's say you're low on vitamin E, and decide to eat a food that is not nutrient dense. A slice of run-of-the-mill white bread will give you about 1/10th of a milligram of vitamin E. This 1/10th of a milligram will cost you about 80 calories (the number of calories in a slice of many white breads). Now let's compare this number and amount to a slice of 100% whole wheat bread.
Whole grain products, like most whole foods, are nutrient dense. A slice of 100% whole wheat bread will cost you approximately the same number of calories (about 70-75 calories) but the vitamin E content will be substantially different. Instead of getting only 100 micrograms of vitamin E in exchange for your 70-80 calories, with 100% whole grain bread, you will get between 250 and 500 micrograms. Or, to put it somewhat differently, you would have to eat between 2-1/2 and 5 slices of run-of-the-mill white bread in order to get the same amount of vitamin E as is found in one slice of 100% whole wheat bread. And those extra 1-1/2 to 4 slices would cost you as much as 320 additional calories.
Getting your nutrients from nutrient dense foods is clearly the way to go! Why? Because in this example, it would save you about 320 calories. While that amount might not sound like a lot, in terms of average walking, it would mean an additional 45 minutes of walking just to break even. It would also be the equivalent of a 33-pound weight gain every year if it happened on a daily basis.
