11 Prebiotic Foods For Optimal Gut Health

Lately, it seems like everyone is talking about the benefits of probiotics. You know, the good bacteria that help keep our digestive tract healthy, support a strong immune system and benefit nearly every function in the human body. Supplement companies are paying big bucks to advertise their probiotics on television commercials and magazine print ads. Yogurt companies are bragging about their products that contain “live cultures.” The living bacteria and yeast that we refer to as probiotics are everywhere. But what about prebiotics

prebiotic foods

While they aren’t talked about nearly as much, prebiotics are just as important for our overall health. Unlike probiotics, prebiotics are not alive. Rather, they are a non-digestible form of fiber. This type of fiber acts as food (or fertilizer) for probiotics. This is extremely important because if your beneficial bacteria didn’t have anything to feed off, they would be easily destroyed by your body’s bad bacteria.

Yes, bad bacteria …

In order for your body to function properly, doctors say you should have about 80% good bacteria and 20% bad bacteria. When the bad guys take over, though, health suffers. As a result, you may experience frequent colds, autoimmune disease, chronic fatigue, depression, anxiety, food allergies, digestive issues, weight fluctuations, thyroid disease, skin conditions, and more. So, as you can see, it’s very important to give your body its daily dose of needed prebiotics. 

There are only two ways you can introduce prebiotics into your body — through supplements or the food you eat. There are a number of nourishing foods that are rich in prebiotics. Below are 11 of the top prebiotic foods for optimal gut health. Chances are, you are already eating some of these prebiotic foods and didn’t even know their health benefit. 

1) Chicory Root

64.6% fiber by weight

Chicory root belongs to the same family as sunflowers and daisies. It’s also considered a cousin to lettuce and dandelions. While the plant is often used in salads, it’s also commonly used to make coffee. Since chicory root tastes similar to the popular morning beverage, but doesn’t have any caffeine, some people like to grind it up and add it to boiling water. This process leaves you with chicory root “coffee.” 

Chicory root has been used for its medicinal purposes for centuries. Ancient Egyptians and Ancient Romans consumed the herb in large amounts because they believed it could purify the blood and support liver health. That’s because it’s loaded with key vitamins, minerals, and antioxidants. Today, we know chicory root as one of the most powerful prebiotic foods out there. It contains a prebiotic called Inulin, which is vital to immunity and digestive health. While other plants also contain this prebiotic, chicory root touts the highest concentration.

Along with boosting immunity and improving digestion, inulin has been known to protect heart health, bone health, and aid weight loss. In one study, a group of 48 overweight adults were given either 21 grams of inulin or a placebo every day. After 12 weeks, researchers found the group who ingested the inulin experienced a decrease in hunger and lost weight.

2) Jerusalem Artichoke

31.5% fiber by weight

When you hear the name “Jerusalem artichoke” you probably think of the large green globe-like vegetable that’s used to create spinach and artichoke dip (my goodness that stuff is yummy). That isn’t the case, though. While it may be confusing at first, artichokes and Jerusalem artichokes aren’t the same. Rather, a Jerusalem artichoke resembles ginger root. Much like ginger root, Jerusalem artichokes (often called sunchokes) are extremely nutritious. Along with being rich in iron, potassium, and key vitamins, it’s a great source of the prebiotic inulin. 

While you can eat Jerusalem artichokes raw or cooked, if you’re looking for the best source of prebiotics, you’re encouraged to eat them raw. Inulin’s content is altered by cooking due to high heat.

3) Dandelion Greens

24.3% fiber by weight

Dandelions aren’t just pretty flowers in your garden or field … they’re also edible. You can add dandelion greens to tea, soups, salads, and sandwiches. While all parts of the flower are nutritious, dandelion greens are rich in vitamins A, K, potassium, calcium, iron, and the prebiotic inulin. In fact, dandelion greens are 24.3 percent fiber by weight. That means they’re one of the best prebiotic foods you can consume.

4) Garlic

17.5% fiber by weight

Garlic is not only the perfect flavor enhancer for your Italian food, but it’s also loaded with good-for-you nutrients that have a major impact on the body. Garlic is a bulbous root that has been known to lower high blood pressure, fight cancer, boost immunity, and fight inflammation. It has antiviral and antifungal properties. Of course, those are just a few of garlic’s many health benefits. Since it’s also a prebiotic food, garlic plays a large role in diversifying our gut microbiome. Researchers say, as a general rule of thumb, the more diverse our gut bacteria is, the healthier we are!

When shopping for garlic in your local grocery store, you will notice it comes in many forms — minced, powder, flakes, or paste. If you want to reap the biggest benefits, though, doctors say to reach for fresh garlic.  Additionally, while cooked garlic still has nutritional value, it’s best to eat it raw.

5) Leeks

11.7% fiber by weight

The leek is a popular plant related to onions, garlic, and shallots. Being from the same family as some powerhouse veggies, it’s no wonder leeks pack a powerful nutritional punch. Along with having antibacterial, antiviral, and anti-fungal properties, leeks have proven to work well as both a diuretic and a laxative. Plus, they contain cancer-fighting properties and support heart health. The health benefits don’t end there, though. With 11.7 perfect of fiber by weight, leeks are considered a powerful prebiotic food. It’s important to note that not all high-fiber foods are considered prebiotic foods. Rather, prebiotics are a certain type of fiber.
