Over the past decade, the term gut health has taken the health and fitness world by storm. The term gut refers to the long, tube-like structure of your digestive system that includes the stomach, small intestine, and large intestine. Other, smaller organs—such as the esophagus, liver, pancreas, and gallbladder—are also considered to be part of the gut.
Here, we'll take a look at why gut health is so important, the effectiveness of popular supplements and other products marketed to support gut health, foods that can support and heal gut health, and how Evidation can provide you with the support you need as you work to improve your overall health.
Why is gut health important?
Some healthcare providers are beginning to view the gut as the body's "second brain," and are working to understand the links between gut health and other parts of the body. The gut plays a vital role in many aspects of overall well-being, including digestion, nutrient absorption, immune function, mental health, and more. The gut microbiome—the collection of bacteria, fungi, viruses, and other microbes—requires balance in order to promote good health, and an imbalance in the microbiome can leave you more susceptible to a wide range of health conditions.
Some of the reasons why gut health is so important include:
- Digestive function: Your gut works to break down food and absorb nutrients. When the gut is not healthy, this process can be disrupted, making it harder for your body to get essential vitamins and minerals to support other bodily processes.
- Immune system: 70% of the body's immune tissue resides in the gut. The body's ability to fight off infection can be positively or negatively affected by gut health. When the gut is unhealthy, it may be easier for pathogens, bacteria, and viruses to cause illness in the body.
- Mental health: Commonly referred to as the gut-brain axis, there's a strong connection between the gut and the brain. When the gut microbiome is not balanced, negative mental health symptoms like mood issues, higher levels of stress, anxiety, and depression can all become more likely.
- Disease prevention: Many diseases—including autoimmune conditions, cardiovascular diseases, diabetes, and some types of cancer—are linked to inflammation. While there are many factors that contribute to the development of these diseases, a balanced, healthy gut may help to prevent some of these conditions.
- Weight management: The balance of bacteria in your gut plays a role in how your body processes and breaks down food, stores fat, and regulates your hunger hormones. An imbalance in gut bacteria may be linked to obesity and other metabolic conditions.
- Skin health: Many skin conditions, including acne, rosacea, psoriasis, and eczema have been linked to an imbalance in gut bacteria.
Popular gut health products—Are they effective?
Gut health supplements—particularly, prebiotics and probiotics—may have a positive effect on your gut health. While the benefits of these products have not been definitively proven, you may find that adding gut health supplements to your diet helps to support healthy digestion or other areas of your overall well-being.
Generally, gut health supplements fall into two categories: prebiotics and probiotics. Prebiotics are foods (or supplements made from foods) that act as food for the naturally-occurring microflora in the gut. Probiotics are foods or supplements that contain live microorganisms intended to increase the amount of good bacteria that already exists in the gut.
Creating a diet that supports gut health
While supplements can be helpful to your health, it's better to get the pre- and probiotics that you need from whole food sources.
Foods high in prebiotics include:
- Whole grains
- Bananas
- Greens
- Onions
- Garlic
- Soybeans
- Artichokes
Foods high in probiotics include:
- Yogurt
- Sauerkraut
- Miso
- Kombucha
- Pickles
- Kefir
- Kimchi
Gut-healing foods
If you or your healthcare provider believe you may be having an issue with gut health, you may be interested in following a diet that supports digestive health. Some healthcare providers believe there may be a phenomenon known as leaky gut syndrome, in which the walls of the intestines become more permeable than normal, allowing undigested food particles and bacteria to leak through the intestinal wall, eventually hitting the bloodstream. Leaky gut syndrome has yet to be proven by research, but some care providers believe that it may contribute to symptoms including food sensitivities, inflammation, and autoimmune diseases.
Foods that can help to heal gut issues, potentially including leaky gut syndrome, include:
- Bone broth to provide the collagen necessary for the gut lining to heal
- Fermented foods rich in probiotics (like yogurt and kefir)
- Leafy greens, ginger, and turmeric to reduce inflammation
Avoiding certain foods may also be a part of the gut healing process, depending on your needs. Many healthcare providers recommend that people working to heal potential leaky gut syndrome stay away from processed foods, refined sugars, and gluten.
If you think you may be having gut health issues, it's important to talk with your doctor before making major changes to your diet.
