What is a characteristic of a nutrient that is considered "empty calories"?

A nutrient considered "empty calories" is characterized by being low in nutrients. This term refers to foods and beverages that provide a high number of calories but lack essential vitamins, minerals, and other beneficial compounds. For instance, many sugary snacks, sodas, and processed foods fall into this category because they offer energy primarily from added sugars and fats without contributing to the overall nutritional needs of the body.

In contrast, options such as high in fiber, low in sugar, or high in protein are indicative of nutrient-dense foods. Foods high in fiber tend to be more beneficial for digestion and satiety, low-sugar options are often healthier choices that contribute to better overall health, and high-protein foods support muscle maintenance and repair. However, "empty calories" specifically highlights the lack of nutrient value, making the identification of choices as low in nutrients essential.
