Discretion should be used to determine whether one snack is a better choice than another based on nutrient density.

In contrast to nutrient density, energy density is the amount of calories per gram of food.

These foods are high in calories, fat, salt, and have a very low nutrient density.

One must learn the relative nutrient density of various foods.

At low nutrient density, Trichoplax maintains a constant speed in order to uncover food sources without wasting time.

Note: The highlighted value is the highest nutrient density amongst these staples.

The higher the value, the more nutrition per calorie (nutrient density) and the least negative factors in the food.

Freshly harvested raw walnut seeds with water content between 2 to 8 percent offer the best color, flavor and nutrient density.

Most commonly, nutrient density is defined as a ratio of nutrient content to the total energy content.

Second, nutrient density is defined as a ratio of food energy from carbohydrate, protein or fat to the total food energy.
