What does nutrient density refer to?

1. The amount of calories a food contains

2. The amount of nutrients relative to calorie content

3. The total mass of a food item

4. The ratio of carbohydrate to fat in a food

The correct answer is: The amount of nutrients relative to calorie content

Nutrient density refers to the amount of nutrients a food contains in relation to its calorie content. Foods that are nutrient-dense provide a high number of essential vitamins, minerals, and other beneficial compounds while minimizing empty calories — calories with little to no nutritional value. This concept is important for making healthier choices, as it helps individuals select foods that contribute to their nutritional needs without exceeding caloric limits. For example, fruits, vegetables, whole grains, and lean proteins typically exhibit high nutrient density because they offer substantial nutrition in a relatively low-calorie package. Understanding nutrient density allows individuals to prioritize foods that support overall health and well-being without unnecessary excess calories.
