9 WAYS TO IMPROVE YOUR GUT HEALTH
These lifestyle changes can help keep your gastrointestinal tract happy
KEY TAKEAWAYS
Gut health affects more than digestion. The gut microbiome is connected to immune function and may also influence mental health, energy, and overall well-being. Imbalances in the gut microbiome, known as dysbiosis, have been associated with conditions such as IBS and changes in mood and energy.
A diverse diet supports a healthy gut. Eating a variety of fruits, vegetables, whole foods, and fermented foods can help support beneficial gut bacteria. Limiting excessive alcohol and added sugars may also be beneficial.
Lifestyle habits matter, too. Regular physical activity, good oral hygiene, adequate sleep, stress management, and staying hydrated can all contribute to overall gut health.
Pay attention to potential warning signs. Digestive problems, persistent fatigue, and changes in mood may occur alongside poor gut health, although these symptoms can have many other causes. Persistent or concerning symptoms should be discussed with a healthcare professional.
If you think your stomach’s only job is to digest food, think again. Your gastrointestinal tract plays an important role in immune function and is connected to the gut-brain axis, which links the digestive system with the nervous system and mental well-being.
An unhealthy or imbalanced gut microbiome, sometimes referred to as dysbiosis, has been associated with inflammation and conditions such as irritable bowel syndrome (IBS). It may also be associated with symptoms including diarrhea, constipation, bloating, headaches, fatigue, and changes in mood.
Improving gut health won’t necessarily resolve every symptom or condition, but supporting your gut may be a useful part of an overall approach to better health—especially if you’ve been experiencing persistent digestive symptoms without a clear cause.
Here’s what you need to know about gut health, how it may affect your overall well-being, and the everyday habits that can help support a healthier gut.
What is gut health?
The “gut” refers to the entire gastrointestinal (GI) system, including the mouth and throat, esophagus, stomach, intestines, and rectum. But good gut health involves more than simply having a stomach that digests food properly.
A healthy gut generally means having normal digestive function, minimal gastrointestinal symptoms, and a balanced gut microbiome. The microbiome is the community of microorganisms that live throughout the GI tract and includes many beneficial bacteria.
Several factors can disrupt this balance, including:
- Poor nutrition
- Chronic stress
- Lack of sleep
- Excessive alcohol consumption
- Certain medications, including antibiotics
- Smoking
Signs of possible gut health problems
Digestive symptoms may include:
- Abdominal pain or cramping
- Bloating or excessive gas
- Diarrhea
- Constipation
Other symptoms have also been associated with gut health concerns, including:
- Fatigue
- Muscle or joint pain
- Skin problems
- Difficulty concentrating or “brain fog”
- Food intolerances
- Headaches
- Nutrient deficiencies
- Anxiety or depression
The gut also has an important relationship with the immune system. A large portion of immune activity is associated with the gastrointestinal tract, where the microbiome helps interact with and regulate immune responses. An imbalance in the microbiome may affect this relationship.
There is also a well-established gut-brain connection. The nervous system within the GI tract communicates with the brain through multiple pathways, which can influence digestion, stress responses, and aspects of mood and well-being.
In other words, the gut does much more than process food. Supporting healthy digestion and a balanced microbiome can be an important part of overall health.
How to improve gut health
The reality is that most of us could benefit from paying more attention to our gut health. The good news is that supporting your gut doesn’t have to be complicated—you can start with a few simple lifestyle changes.
One key goal is to support a diverse gut microbiome, meaning a healthy variety of beneficial microorganisms living in your digestive tract. Here are some practical ways to get started.
1. Eat a variety of foods
Here’s an interesting area of research: greater diversity in the gut microbiome is generally associated with better gut health. One practical way to support microbiome diversity is to eat a wide variety of nutritious, minimally processed foods, including fruits, vegetables, legumes, and lean protein sources.
Nutrition experts often recommend incorporating different types of fresh, colorful whole foods into your meals, from berries and avocados to dark leafy greens and lentils. Variety matters because different foods provide different fibers and plant compounds that can support different types of beneficial gut bacteria.
Research published in Food & Function also suggests that polyphenol-rich foods, including artichokes, apples, and blueberries, may have protective effects against the growth of certain harmful bacteria in the gut.
2. Limit alcohol and added sugar
According to Inna Melamed, Pharm.D., alcohol can negatively affect the gut microbiome and may also interfere with melatonin production and sleep. Since adequate sleep is an important part of overall health, reducing alcohol intake may be one way to support healthier lifestyle habits.
Added sugars may also contribute to inflammation and changes in the gut microbiome. This includes limiting highly processed foods and beverages that are common in a typical Western diet. Reducing excess added sugars, including foods containing some artificial sweeteners, may help support a healthier balance in the gut.
3. Eat fermented foods
One commonly recommended way to support gut health is to include fermented foods in your diet. Many fermented foods contain probiotics—live microorganisms that may help support a balanced gut microbiome and beneficial bacteria such as Lactobacillus.
Examples of fermented foods that may provide probiotics include:
- Kefir
- Yogurt
- Miso
- Kombucha
- Kimchi
- Sauerkraut
Some fermented foods may also provide postbiotics, which are beneficial compounds produced when microorganisms metabolize components of food. Other foods sometimes recommended as sources of beneficial compounds include buttermilk, seaweed, and cottage cheese.
Because fermented foods can affect people differently, especially those with certain digestive conditions or food sensitivities, introduce them gradually and pay attention to how your body responds.
4. See your dentist regularly
Maintaining good oral hygiene can therefore be an important part of overall digestive health. Dr. Melamed recommends regular brushing and flossing, along with routine dental cleanings and checkups, to help maintain a healthy oral microbiome.
5. Get enough exercise
Regular exercise benefits many aspects of health, and research suggests it may also support a healthier and more diverse gut microbiome. One study found that athletes had greater gut bacterial diversity and higher levels of certain beneficial bacteria compared with less-active individuals.
Regular physical activity may also support healthy gut function and intestinal barrier integrity. Dr. Burkhart recommends aiming for at least 30 minutes of exercise five or more days per week, depending on your fitness level and healthcare provider’s recommendations.
You don’t necessarily need intense workouts—walking, cycling, swimming, and other moderate activities can be practical ways to stay active consistently.
6. Focus on fiber
While you’re working on eating a wider variety of foods, don’t forget about fiber. Many Americans don’t consume enough fiber each day, yet dietary fiber plays an important role in supporting beneficial gut bacteria.
Increasing your intake of fiber-rich foods may help support a healthier and more diverse gut microbiome. Good sources include:
- Leafy green vegetables
- Whole grains
- Legumes
- Nuts and seeds
- Apples and pears with the skin
- Berries
Dr. Burkhart suggests aiming for around 30–35 grams of fiber per day. If you currently eat very little fiber, increase your intake gradually and drink enough fluids to help prevent digestive discomfort.
7. Sleep more
Did you know that sleeping is good for your gut? It’s true: The better you sleep, the more types of bacteria grow in your gut, making a strong case for getting enough sleep every night.
“[While you sleep], the digestive system is busy regenerating and repairing tissues in our gut,” Dr. Melamed says. “We also grow more good gut bacteria during the night, which helps us have a better digestive process.”
8. Stress less
The gut-brain connection works in both directions. Changes in gut health may be associated with anxiety and depression symptoms, while stress and emotional well-being can also affect digestion and the gut microbiome.
“Managing stress is an important piece of the gut health puzzle,” says Dr. Burkhart. Developing a simple daily stress-management routine may help support both mental and digestive well-being.
Some options include:
- Breathing exercises
- Meditation
- Reading
- Journaling
- Spending time in nature, such as taking a 20-minute walk outdoors
The goal isn’t to eliminate all stress—it’s to develop healthy ways to manage it consistently.
9. Stay hydrated
Last but not least, stay hydrated. Drinking enough fluids supports normal digestion and overall health, while dehydration can contribute to constipation and other digestive discomfort.
Dr. Burkhart suggests drinking around six to eight glasses of non-caffeinated fluids per day, although individual fluid needs can vary depending on factors such as activity level, climate, and health conditions.
If you prefer something other than plain water, unsweetened herbal teas can also contribute to your daily fluid intake. Options such as chamomile, dandelion, rose hip, and hibiscus tea can be enjoyable ways to stay hydrated.
Rather than relying on beverages for “detoxing” the gut, focus on consistent hydration, a balanced diet, and healthy lifestyle habits that support normal digestive function.
When to see a doctor for gut health
Symptoms of an unhealthy or inflamed gut can vary from person to person. However, Dr. Melamed recommends paying attention to signs that may warrant a conversation with your primary care provider or a gastroenterologist, including:
- Irregular bowel habits
- Chronic constipation
- Heartburn or indigestion
- Persistent bad breath
- Frequent stomach pain
Keeping a symptom journal can help you track how often these symptoms occur and whether certain foods or habits seem to trigger them.
“It’s very important to be proactive when it comes to healing the gut,” Dr. Melamed says. Persistent digestive symptoms shouldn’t simply be dismissed as normal, especially when they interfere with your daily life.
Depending on your symptoms and medical history, a healthcare provider may recommend lifestyle changes such as eating more fresh, whole foods, getting adequate sleep, exercising regularly, or adjusting certain foods. They may also consider probiotics or refer you to a gastroenterologist if further evaluation is needed.
