Superfoods. Great word but what does it connote? Foods that are super? Yes, but how? Technically, there’s no set criteria for what defines a superfood.

Instead, the term “superfood” simply means that the food (or spice) is rich in nutritional value and can play a key role in your health if you make it part of your daily or weekly diet. For example, some superfoods play a role in boosting gut health, others contribute to healthy aging, and many simply assist with overall health.

So what are the best superfoods that may contain plenty of nutrients while also offering some concrete health benefits? Here are 18 superfoods worth considering adding to your eating plan.

1. Kale

One of the most nutrition-rich plants are leafy greens, also known as leaf vegetables, green vegetables or dark leafy greens. Perhaps the best known for being a superfood is kale, but collard greens, mustard greens, spinach and others can also be given this title, too.

These vegetables are packed with vitamins, particularly vitamin A, vitamin C and vitamin K, which play vital roles in maintaining overall health and supporting various bodily functions. Kale also includes invaluable bioactive compounds like lutein, beta-carotene, nitrates, kaempferol and α-tocopherol.

Key nutrients:

A one-cup serving of raw kale (about 21 grams) contains 81.9 mcg of vitamin K (685 DV) and 19.6 mg of vitamin C (22% DV).

How to use:

Add kale to nearly any cooked dish, make up kale “chips” in the oven or use baby kale in your smoothie or salad.

2. Bone broth

Bone broth is made by simmering the bones and connective tissue of animals such as cattle, fish or chicken with herbs and vegetables. This creates a nutrient-filled stock that is full of collagen, amino acids and important minerals.

The amino acids (the building blocks of protein) found within bone broth help maintain the structure and function of many different body parts, including the lining of your organs and gastrointestinal tract. A strong and healthy gut lining helps support to overall healthy gut function, nutrient absorption and even support for a healthy immune system (since most of your immune system is located inside your gut).

Key nutrients:

Contains collagen, which breaks down into gelatin and amino acids like glycine and arginine. Also contains minerals like calcium, magnesium, phosphorus and potassium.

How to use:

Drink some on its own as a nutrient-rich beverage, or add it to soup, stews and marinades. You can use a powder version in baked recipes, too.

3. Blueberries

Berries are incredibly rich in antioxidants, especially flavonoids, and help support heart and brain health. The anthocyanins in blueberries support healthy inflammation levels and support cognitive function.

Cranberries and raspberries are similar berries that contain polyphenols, ellagic acid, carotenoids and anthocyanin to offer various health benefits.

Key nutrients:

A one-cup serving of raw blueberries (about 148 grams) provides 28.6 mcg of vitamin K (32% DV), 0.5 mg of manganese (28% DV) and 14.4 mg of vitamin C (19% DV).

How to use:

Toss fresh or frozen blueberries into your smoothie, use in baked goods like pancakes, or even use in a salad for a little bit of sweetness.

4. Bovine colostrum

It’s one of nature’s original superfoods. Colostrum is a form of milk produced by mammals like humans and cows during late pregnancy and the first few days after giving birth. Commonly called “liquid gold,” it is thicker, yellowish and more nutrient-filled than regular milk.

While it is most associated with infant nutrition, bovine colostrum (from cows) is fast becoming a popular supplement for adults due to its health-boosting properties.

Key nutrients:

It’s packed with lactoferrin and immunoglobulins IgA and IgG.

How to use:

Ancient Nutrition's Colostrum powder comes unflavored or lemon bar flavor, with both naturally slightly sweet. It’s easy to blend into your favorite drinks without overpowering other flavors. Recipes include smoothies, yogurt, juice or water (8 ounces).

7. Salmon

Oily fish like salmon are high in heart-supporting omega-3s that can also support healthy inflammation levels and brain health.

13. Turmeric

Turmeric has been in the human diet for over 4,000 years and supports healthy joint function, a healthy response to inflammation and muscle strength. Many of the benefits are attributed to its powerful compound curcumin.

Key nutrients:

In addition to turmeric supplements — such as Ancient Nutrition's Organic Turmeric Tablets — there are several other options for getting in your daily serving. Turmeric powder, for example, can be used to make turmeric tea, turmeric shots or added to dishes for a bit of extra flavor and color. Consider pairing turmeric with black pepper (like the above supplement does), as this has been shown to enhance curcumin absorption.

16. Chia seeds

Chia seeds are a true superfood. Originally grown in Mexico, chia means “strength” in the Mayan language, and chia seeds were known as “runners’ food” because runners and warriors would use them as fuel while running long distances or during battle.
