How pre and probiotics work together to support gut health

You've likely heard of the importance of prebiotics and probiotics to support digestive health. Both are key to maintaining a healthy balance of bacteria in the gut, and understanding the difference between the two can help you make smart decisions about nutrition and supplementation.

Here, we'll take a look at the difference between prebiotics and probiotics, explore how the two work together, go over whole food and supplementation options to help you balance your gut health, and check out some healthy recipes that you can use to support healthy digestion.

What's the difference between prebiotics and probiotics?

Both prebiotics and probiotics are essential to maintaining a healthy gut, but they serve different functions in the body. Prebiotics are types of fiber that serve as food for beneficial bacteria that live in the gut, while probiotics are live bacteria that reside in the gut and provide health benefits when consumed.

Probiotics are hard at work in your digestive system, and eating foods like kefir, sauerkraut, kimchi, and yogurt can help increase their numbers. In addition to helping you effectively digest food, probiotics support immune health, help to manage cholesterol and blood sugar levels, and may even contribute to better moods and mental health. While eating any type of probiotic food can support digestive health, it's important to diversify your intake when possible. Different types of probiotics come from different foods, and creating a diverse probiotic environment can help you feel your best.

Prebiotics are non-digestible fibers that support the health of probiotics. Bananas, onions, garlic, leeks, asparagus, and whole grains all contain prebiotics. While prebiotics don't introduce new bacteria to the gut, they do help your existing probiotics support your well-being. Prebiotics aren't only good for your probiotics—they help to support other aspects of digestive health by reducing inflammation in the gut and enhancing nutrient absorption. Prebiotics can also help to manage blood sugar and increase calcium absorption.

How prebiotics and probiotics work together

At birth, each person already has a unique gut microbiome. We can maintain and repair the health of the gut microbiome by providing existing bacteria with prebiotic food, as well as adding new bacteria by eating probiotics.

For probiotics to do the hard work of maintaining a healthy microflora environment in the gut, they need fuel. Prebiotics help probiotics function effectively. You have more than 100 trillion good bacteria living in your gut, and providing them with support is vital for your overall health.

Supplementation vs. whole foods

Generally, it's best to get prebiotics and probiotics from whole food sources. These tend to offer a greater variety of prebiotics and probiotics than supplements. That being said, if your healthcare provider recommends that you take a specific type of prebiotic or probiotic to treat a condition, it may make more sense to use a supplement. An important note: prebiotic and probiotic supplements aren't regulated by the FDA, so it's smart to talk with your doctor about the supplement brands that make the most sense for your needs. You'll also need to pay close attention to the storage instructions for prebiotic and probiotic supplements, as some are not shelf-stable.

Why balanced gut health matters

Maintaining a healthy variety of probiotics in the gut—and supporting those bacteria with prebiotics—is essential for health and well-being.

Poor gut health is linked to a number of symptoms and health conditions, including:

  • Digestive issues like bloating, heartburn, irritable bowel syndrome, constipation, and diarrhea
  • Autoimmune conditions like thyroid problems, rheumatoid arthritis, and childhood eczema
  • Sleep problems
  • Difficulty maintaining a healthy weight (potentially due to sugar cravings associated with poor gut health)
  • Mental health issues like depression and anxiety

Prebiotic and probiotic recipes

Thankfully, improving your gut health can go a long way in alleviating symptoms associated with an imbalance in your digestive system's microbiome. Let's take a look at some recipes packed with ingredients that can help get your gut health back on track.
