How To Keep Your Gut Happy: Nutrition for Good Gut Health
heNutrition for Good Gut Health
The food that we eat has a direct influence on our gut health and its ability to function properly. Certain foods can promote the growth of good bacteria, support digestion, and protect the gut lining. While other foods can throw off the balance of the gut, creating an environment with more bad bacteria than good bacteria. This can cause digestion issues and other overall health complications. Good nutrition also flourishes the connection between the gut and the brain, known as the gut-brain axis. Fueling the gut microbiome with the right foods can improve overall mood and mental health.
What does nutrition for good gut health include and why is it important?
Gut health refers to the function of the digestive system and the gut microbiome. The gut microbiome is made up of about 200 different kinds of bacteria, fungi, and viruses that line the gastrointestinal tract. These microorganisms are responsible for different digestive functions, such as breaking down food and absorbing nutrients. They play a crucial role in maintaining overall health and preventing disease.
The gut microbiome is in good standing when the good bacteria in the GI tract outweighs the bad bacteria. The good bacteria helps to ensure that food is digested properly and that the nutrients can be adequately absorbed and used by the rest of the body. When the gut microbe balance is disrupted, it can be presented in different symptoms, such as:
- Bloating
- Constipation
- Diarrhea
- Cramping
- Skin problems (acne, eczema)
- Low energy or chronic fatigue
- Weakened immune system
- Mental health issues (anxiety, depression)
Foods to Embrace for Good Gut Health
Embracing good nutrition can help the gut microbiome to flourish, feeding good bacteria that allow the body to function properly. There are certain foods and nutrition practices to incorporate to promote good gut health. Foods that promote good gut health are:
- High in fiber
- Probiotics
- Prebiotics
- Healthy fats
It’s also important to stay hydrated, as this supports good digestion and the health of the gut lining.Fruits and vegetables that are different colors are rich in different vitamins and minerals, that’s why it’s important to incorporate a colorful variety into your diet.
Fiber
Fiber is a type of carbohydrate that the body doesn’t digest. It aids in digestion and supports regular bowel movements, making it crucial for optimal gut health. There are two types of fiber, insoluble fiber and soluble fiber. Insoluble fiber adds bulk to stool and helps it move through the digestive tract more easily, preventing constipation and promoting good gut motility. It can be found in whole grains, vegetables, and nuts.
Soluble fiber dissolves in water, forming a gel-like substance. This substance is fermented by gut bacteria in the colon, acting as a prebiotic, providing food for the bacteria. Once the soluble fiber is fermented, it produces short chain fatty acids, which promote a healthy gut microbiome. They also help to reduce inflammation in the GI tract, which can alleviate GI disorders such as irritable bowel syndrome (IBS). Soluble fiber can be found in oats, beans, fruits, and vegetables. This is why it’s important to eat a variety of foods, so that you are receiving adequate amounts of both types of fiber. Both types of fiber work to promote the growth of good bacteria that help digest food, synthesize vitamins, and protect the body from harmful pathogens.
Probiotics and Prebiotics
These microorganisms play a large role in promoting good gut health. Probiotics are live microorganisms that feed good gut bacteria, helping to fight off harmful microbes and maintain balance in the GI tract. Probiotics also aid in the breakdown of food and act as anti-inflammatories, reducing symptoms of bloating, diarrhea, and constipation. They help to strengthen the gut barrier that lines the GI tract, protecting the body from harmful toxins. This is crucial for reducing infection and preventing diseases, such as leaky gut syndrome. This is a condition where damaging substances leak through the gut lining and enter the blood stream. Probiotics are largely found in fermented foods with live bacteria, such as:
- Greek yogurt
- Kimchi
- Kefir
- Kombucha
- Sauerkraut
- Tempeh
Prebiotics are non-digestible components of food, typically fiber, that promote the growth of good gut bacteria. Compared to probiotics, which are live bacteria, prebiotics act as food for gut bacteria. Humans don’t have the enzymes to break down prebiotics, so they are fermented by the gut microbiome in the colon. Feeding good bacteria, such as Bifidobacteria and Lactobacilli, enhances nutrient absorption, digestion, and immune function. There are different types of prebiotics and they can be found in a variety of different foods. Foods rich in prebiotics are:
- Fruits – bananas, apples, berries, and citrus fruits contain inulin, a prebiotic fiber
- Vegetables – garlic, onions, leeks, asparagus, and artichokes
- Whole grains – oats, barley, and whole wheat
- Legumes – beans, lentils, and chickpeas
- Nuts and seeds – almonds, walnuts, and flaxseeds
Healthy Fats for Good Gut Health
Healthy fats, specifically omega-3 fatty acids, strengthen the gut lining of the GI tract. Omega-3 fatty acids can be found in fatty fish, such as salmon, and nuts, such as walnuts and flaxseeds. Healthy fats also have anti-inflammatory properties that alleviate symptoms related to poor gut health. They provide a source of short chain fatty acids, produced when fiber is fermented in the colon, that support gut health. Consuming healthy fats also aids in the absorption of fat soluble vitamins (vitamin A, D, E, and K) and gut motility.
Types of healthy fats include monounsaturated and polyunsaturated fats. Polyunsaturated fats include omega-3 and omega-6 fatty acids, both crucial to gut health. Monounsaturated fats can be found in olive oil, sunflower oil, avocados, and almonds. Polyunsaturated fats can be found in salmon, anchovies, peanuts, and walnuts.
Foods to Limit
While there are foods that promote good gut health, there are also foods that can be harmful to the gut.These foods disrupt the balance of the microbiome, which can lead to indigestion and stomach discomfort. Foods that should be limited for good gut health:
- Highly processed foods and meat products (bacon,sausage)
- Fried foods
- Foods with high amounts of added sugar and/or unhealthy fats
- Highly acidic foods
- Spicy foods
- Sugary sweetened beverages
- Alcohol
Whether these foods are high in sugar, unhealthy fats, or sodium, they are capable of having a negative impact on gut health. They should be enjoyed in moderation in order to promote the growth of good bacteria to maintain microbiome balance.
Want to learn more about nutrition for good gut health?
Fueling the body with foods that are beneficial to gut health and the growth of good bacteria allows for optimal digestion. This means good gut motility, proper nutrient absorption, strong GI tract lining, and enhanced immune function. This prevents digestion complications such as bloating, constipation, and diarrhea. It also prevents and alleviates symptoms of more serious digestive issues such as irritable bowel syndrome, inflammatory bowel disease, and leaky gut syndrome. Remember to start with small changes in your diet, as they can have a big impact over time. If you want more help with nutrition related to gut health, schedule a consultation with us!
