Define nutrient density and give an example illustrating the concept.

• A. Nutrient density is the ratio of calories to nutrients per serving.
• B. Nutrient density is the speed of nutrient absorption.
• C. Nutrient density is nutrients per calorie; example: kale is nutrient-dense; refined white bread is energy-dense but less nutrient-dense.
• D. Nutrient density relates to macro-nutrient distribution.

Answer: (C)

Nutrient density describes how many nutrients you get from a food relative to its calorie content. In other words, it’s nutrients per calorie. Foods that are nutrient-dense deliver a lot of vitamins, minerals, and other beneficial compounds for relatively few calories. A classic example is kale, which is rich in vitamins A, C, and K, as well as minerals, fiber, and antioxidants, yet low in calories, so it provides substantial nutrition for a small energy cost. Refined white bread, by contrast, supplies calories mainly from carbohydrates with fewer micronutrients, making it energy-dense but less nutrient-dense. This concept helps guide choices to maximize nutrition without excess calories.
