Which is classified as a nutrient dense food according to the dietary guidelines for Americans?

Unfortunately, the question doesn't give me any options to choose from! To tell you which food is nutrient-dense, I need a list of options.

However, I can give you some general guidelines for identifying nutrient-dense foods based on the Dietary Guidelines for Americans:

* Focus on fruits, vegetables, and whole grains. These foods are naturally low in calories and fat, and they're packed with vitamins, minerals, fiber, and antioxidants.

* Choose lean protein sources. Opt for fish, poultry, beans, lentils, and tofu over red meat and processed meats.

* Choose low-fat dairy products. Look for milk, yogurt, and cheese that are low in fat and high in calcium.

* Limit added sugars, saturated and trans fats, and sodium. These ingredients can add extra calories and unhealthy fats to your diet.

Examples of nutrient-dense foods:

* Fruits: Berries, apples, bananas, oranges

* Vegetables: Broccoli, spinach, carrots, sweet potatoes

* Whole grains: Brown rice, quinoa, oats

* Lean protein: Salmon, chicken breast, beans, lentils, tofu

* Low-fat dairy: Skim milk, Greek yogurt, low-fat cottage cheese

Once you provide me with a list of food options, I can tell you which one is classified as nutrient-dense.
