What might indicate a food has high nutrient density?

A food with high nutrient density is characterized by a high concentration of vitamins and minerals relative to its calorie content. This means that for a given number of calories, the food provides a significant amount of essential nutrients, such as vitamins, minerals, fiber, and protein, without being excessively high in calories. This makes it a valuable choice for those looking to improve their overall nutrition without consuming more calories than necessary.

In contrast, options that focus on calorie count or the presence of sugar do not directly relate to nutrient density. A high calorie count can indicate energy-dense foods that may not provide the necessary nutrients, while low sugar content alone does not ensure high nutrient density. The presence of artificial ingredients might also imply lower nutrient value and does not contribute to the definition of nutrient density. Thus, the best indicator of high nutrient density is the concentration of essential vitamins and minerals compared to calorie content.
