You may have been hearing a lot about gut health lately. Everywhere you turn, someone is touting the benefits of gut health or talking about the gut microbiota in some way. If you don’t know what any of that means, don’t worry, I’m about to explain!

What is Gut Health?

What exactly does ‘gut health’ mean? It has to do with the bacteria that live in your intestines. Research continues to emerge that the environment of good bacteria in your gut, or the microbiota, can influence many aspects of your health, including digestion and absorption of nutrients, vitamin synthesis, immunity, weight, gastrointestinal disease, and even the development of diseases such as type 2 diabetes and heart disease!

Luckily, you can influence your gut health through your diet. Eating foods rich in prebiotics and probiotics can help you build up good bacteria in your gut to help keep you healthy. You’ve probably heard of probiotics, but what about prebiotics?

Prebiotics and Probiotics: What they are and where to find them

Prebiotics are basically the food that the good bacteria eat. They come from non-digestible fiber in certain foods, and they promote the growth of probiotics. Some food sources of prebiotics include:

Probiotics, on the other hand, are the actual good bacteria that live in your gut. They can get wiped out by antibiotics, stress, and a chronic unhealthy diet. To build up the probiotics in your gut, include prebiotics in your diet and fill up on these probiotic-containing foods:

  • Yogurt
  • Kefir
  • Miso paste
  • Sauerkraut
  • Kimchi
  • Other fermented veggies, like Farmhouse Culture products
  • Tempeh
  • Kombucha

There are also plenty of specialty supplements specifically full of probiotics. Farmhouse Culture and GoodBelly, for example, make probiotic ‘shots’ that you can drink alone or incorporate into salad dressings or smoothies.

Any foods with probiotics must be refrigerated to keep the good bugs alive, so when you’re buying sauerkraut and other fermented veggies look in the refrigerated section. It’s best to eat yogurt and kefir raw and heated products like miso and tempeh should be cooked below 140°F so that you don’t kill the probiotics off. Here’s to a healthy gut!

  1. I eat both, so I think I’m good! 🙂 I was just reading a review about GoodBelly the other day though and it sounds interesting. I think I might give it a try if I ever am feeling some tummy troubles.

    1. That’s great that you get both in Jenn! So happy to hear that. And yes, the GoodBelly products seem interesting. I myself haven’t tried them yet, but I know people who love them.

    1. Hi Alisa! That can be a tricky one for sure! Bananas are low in FODMAPs, but high in prebiotic fiber. You could also try black or pinto beans in small amounts but avoid garbanzos/chickpeas. Try to focus more on the probiotics to help improve his intestinal flora. My cousin had great results with intestinal issues when he started taking a probiotic supplement with an enteric coating, which ensures the healthy bacteria are delivered straight to the large intestine. Try to get his healthy bacteria going with probiotics first, and then trial small amounts of the pre-biotics. Hope that helps a bit!

      1. Thanks Britany for sharing some ideas for Alisa! Alisa, I’ll also add that kiwi fruit is low-FODMAP and a good source of prebiotics.

  2. So many of my favorite foods and for good gut reason! My husband is suppose to be buying us a fridge for our kombucha and probiotics. Plus I love my kimchi, kraut, and so many other good gut foods plus the usual sweet potatoes.

    1. Thanks Emily! There’s so much talk about probiotics, but prebiotics are often left out. Wanted to make sure people knew about the need for both!

  3. […] have a long shelf life (usually a year), but when you enjoy the sweet and salty umami flavor of probiotic-rich miso you want to use it ALL. THE. […]
