Final answer:
The term nutrient dense describes foods that contain a high concentration of essential nutrients per calorie. Nutrient-dense foods include fruits, vegetables, lean meats, fish, low-fat dairy products, and whole grains, which all contribute to a balanced and healthful diet.
Step-by-step explanation:
The term nutrient dense refers to foods that provide a high amount of essential nutrients relative to their calorie content. These foods are contrasted with "empty-calorie" foods, which are low in nutrients compared to the calories they contain. A diet that focuses on nutrient-dense foods will enable you to consume the nutrients needed without excessive calorie intake, supporting better health and often aiding in weight management.
Nutrient-dense foods include a variety of items from different food groups. Examples of such foods are fruits and vegetables, which offer vitamins, minerals, and fiber; lean meats and fish, which provide high-quality protein and essential nutrients; low-fat dairy products, which contribute calcium and protein; and whole grains, which contain fiber and B-vitamins.
To illustrate, consider kale and iceberg lettuce: kale provides substantially more vitamin K per calorie than iceberg lettuce, making it a more nutrient-dense choice. When choosing foods for their nutrient density, consider foods that are high in fiber, proteins, and other vital nutrients. By selecting these types of foods, you optimize your intake of essential nutrients while managing your calorie intake, contributing to a balanced and healthful diet.
