Your gut does much more than digest food. Also called the gastrointestinal (GI) tract, it helps your body absorb nutrients, support your immune system, regulate energy, and even influence your mood. A healthy gut can improve your overall well-being, while an unhealthy gut may contribute to digestive problems and other health concerns.
As your body breaks down food, your gut absorbs the nutrients needed for important functions like energy production, disease prevention, and even brain health.
Research has shown that your brain and gut are closely connected through what's known as the gut-brain axis. The trillions of bacteria, viruses, and fungi that make up your gut microbiome play an important role in digestion, metabolism, sleep, mood, and immune health.
According to the National Institutes of Health, digestive diseases affect an estimated 60 to 70 million Americans, making gut health an important part of staying healthy as you age.
What Are the Signs of an Unhealthy Gut?
An unhealthy gut can affect much more than your digestive system. Common signs may include:
- Frequent bloating, gas, or stomach discomfort
- Chronic pain
- Fatigue or low energy
- Trouble sleeping
- Frequent inflammation
- Unexplained weight loss
- Migraines
- Diabetes
- Depression or anxiety
If you're experiencing ongoing digestive symptoms or changes in your health, talk with your primary care provider to determine the underlying cause.
The good news is that simple lifestyle changes can help support a healthier gut.
1. Eat More Probiotic Foods
Probiotics are beneficial bacteria that help keep your digestive system balanced. They support healthy digestion, strengthen your immune system, and may help reduce inflammation.
Foods naturally rich in probiotics include:
- Yogurt with live cultures
- Kefir
- Sauerkraut
- Kimchi
- Tempeh
- Pickled vegetables
- Kombucha
Adding probiotic-rich foods to your meals can be an easy way to support your digestive health.

2. Feed Good Bacteria with Prebiotic Foods
Probiotics need fuel to thrive. That's where prebiotics come in.
Prebiotics are types of fiber that nourish the healthy bacteria already living in your gut.
Good sources of prebiotics include:
- Bananas
- Apples
- Garlic
- Onions
- Flaxseed
- Oats
- Whole grains
- Asparagus
Eating both probiotics and prebiotics together helps create a healthy balance in your digestive system.
3. Eat Plenty of Fiber-Rich Fruits and Vegetables
Fruits and vegetables are among the best foods for gut health because they're packed with fiber, vitamins, minerals, and antioxidants.
Fiber supports healthy digestion by helping food move through your digestive tract and promoting regular bowel movements.
Aim to:
- Eat at least 3 servings of vegetables each day.
- Include a variety of colorful fruits and vegetables throughout the week.
- Choose whole foods whenever possible.
A diverse diet also helps support a diverse gut microbiome.
4. Be Mindful of Gluten If You're Sensitive
Gluten is a protein found in wheat, rye, and barley. Most people can eat gluten without problems, but individuals with celiac disease or gluten sensitivity may experience digestive symptoms after consuming it.
If you notice bloating, stomach pain, or digestive discomfort after eating foods that contain gluten, speak with your healthcare provider before making major dietary changes. They can help determine whether gluten is contributing to your symptoms.
5. Consider Probiotic or Prebiotic Supplements
While food should be your first source of nutrition, supplements may be helpful if you're unable to get enough probiotics or prebiotics through your diet.
Talk with your primary care provider before starting any supplement, especially if you take prescription medications or have chronic health conditions.
You can also learn how healthy habits help support your immune system.
6. Only Take Antibiotics When They're Needed
Antibiotics can be lifesaving when treating bacterial infections, but they also kill beneficial bacteria in your gut.
Never skip antibiotics that have been prescribed by your healthcare provider. However, avoid requesting antibiotics for illnesses like the common cold or the flu, since these are caused by viruses and antibiotics won't help.
After taking antibiotics, ask your provider whether probiotics or probiotic-rich foods may help restore healthy gut bacteria.
