If you want to get the most out of your meals, try incorporating more nutrient-dense foods. Such options offer a high amount of essential nutrients per serving, making them valuable for supporting health and meeting your daily nutrient needs. What's more, these ultra-nutritious foods tend to provide long-lasting energy, helping you feel your best throughout the day. 

It's important to note that there is no one food that contains all the nutrients your body needs to function and thrive. That's why a balanced diet should contain various ingredients, including fruitsvegetables, lean proteins, and healthy fats and fiber sources. When eaten regularly, these foods will work together to nourish your body while reducing the risk of disease. But even within each category, there are options that stand out in terms of nutrition quality and content. To learn more about them, we asked dieticians to share the most nutrient-dense foods you can eat, plus ways to enjoy them at home.

"Seaweed is one of the most nutrient-dense foods out there, thanks to its unique mix of minerals," says Michelle Luhan, RD, registered dietitian at the Susan Samueli Integrative Health Institute at UCI Health. "It's packed with iron, calcium, zinc, magnesium, potassium—and most notably, iodine," she adds. Low iodine intake is associated with thyroid issues, making iodine-rich foods (like seaweed) a smart choice. Additionally, seaweed contains prebiotic fiber (i.e., food for good gut bacteria) and antioxidants, which protect cells from oxidative stress, says Luhan.

How to Eat

  • Serve premade seaweed salad with sushi bake
  • Sprinkle seaweed flakes on soups, salads, bowls, vegetables, omelets, or popcorn, suggests Luhan.
  • Use seaweed sheets for sushi or hand rolls, or enjoy snack-sized roasted versions, per Luhan.

While seaweed has many pluses, eating too much may cause health risks due to its iodine and heavy metal content. Consult your health care provider if you have concerns.

Pumpkin Seeds

Pumpkin seeds might be tiny, but they pack a nutritional punch. They're rich in zinc and unsaturated fats, which boost immune function and lower blood cholesterol, respectively, says Wagner. Pumpkin seeds are also high in magnesium, offering 1/3 of your daily needs in a 1-ounce serving, says Wagner. This is key because "magnesium makes it easier for our body to use other nutrients in their primary roles," according to Wagner.

How to Eat

  • Roast pumpkin seeds for a simple and flavorful snack.
  • Use pumpkin seeds in trail mix, granola, and salads, says Wagner.
  • Blend pumpkin seeds into your next smoothie, where it will add nuttiness and nutrients.

Kale

While all leafy greens are nutrient-dense foods, kale is especially impressive. In just 1/2 cup of cooked kale, you’ll get more than 600 percent of the daily value of vitamin K, according to Wagner. Vitamin K is needed for bone health and blood clotting, which is vital when you get a wound. Kale is also high in vitamin A (which aids eye and skin health) and vitamin C (which supports immune function), says Wagner.

How to Eat

  • For an easy way to eat more kale, add it to green smoothies.
  • Bake kale chips for a crispy snack.
  • Toss kale into soups or stews for a boost of nutrition, per Wagner.

Extra-Virgin Olive Oil

"Extra-virgin olive oil is a staple in the Mediterranean diet, famous for its heart benefits and anti-inflammatory powers," explains Luhan. More specifically, it's teeming with monounsaturated fats (which help reduce blood cholesterol) and polyphenols, which are antioxidants that reduce inflammation and fight free radicals.

Liver

"In the animal kingdom, liver—especially from grass-fed animals—is a true nutrient superstar," says Luhan. For example, a single 3.5-ounce serving of beef liver will provide all the B vitamins you need for the day, she notes. It's also loaded with vitamin A, copper, zinc, selenium, and heme iron, the type of iron that's highly absorbable, per Luhan. What's more, liver is a high-quality protein, providing all the essential amino acids the body needs.

How to Eat

Kefir

Kefir is a fermented milk product, meaning it's high in probiotics, shares Wagner. Probiotics are bacteria that benefit gut health, ensuring your microbiome stays balanced. Kefir also provides calcium and phosphorus, which help bone health, along with protein for muscle maintenance, says Wagner.

How to Eat

  • Drink kefir like a glass of milk.
  • Add to smoothies, dips, sauces, and dressings, recommends Wagner.
  • Blend kefir with fruit, then pour the mixture into ice pop molds, says Wagner. 

Oysters

A single 3.5-ounce serving of oysters will meet your daily needs for vitamin B12, selenium, and zinc, according to Luhan. The shellfish is also a good source of protein and omega-3 fatty acids, which support heart, brain, and joint health, explains Luhan. In fact, "some oysters have more omega-3s per weight than wild salmon," she adds. 

Foodsafety.gov notes that eating raw or undercooked oysters that contain Vibrio bacteria can make you sick and has tips to reduce your chances of getting an infection.
