10 Simple Ways to Improve Your Gut Health

Your gut does much more than digest the food you eat. Your digestive tract contains a complex community of microorganisms called the gut microbiome. Diet is one of the factors that can influence this microbial community, and research continues to explore how diet and the gut microbiome interact with human health. National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)

The good news is that supporting gut health does not usually require extreme diets or expensive supplements. Simple habits such as eating more fiber-rich foods, choosing a variety of plant foods, staying hydrated, being physically active, and limiting highly processed foods can help support a healthy lifestyle.

Here are 10 practical ways to improve your gut health naturally.

1. Eat More Fiber-Rich Foods

One of the most useful steps for supporting gut health is getting enough dietary fiber.

Fiber is found naturally in plant foods and can support regular bowel movements. Some types of fiber are also used by microorganisms in the gut.

Good high-fiber foods for gut health include:

• Oatmeal and other whole grains
• Beans and lentils
• Chickpeas
• Apples, pears, and berries
• Broccoli and other vegetables
• Nuts and seeds

According to the NIDDK, adults generally need about 22–34 grams of fiber per day, depending on age and sex. It is best to increase fiber gradually because suddenly adding a large amount can cause gas or bloating. Adequate fluids are also important when increasing fiber.

2. Eat a Variety of Plant Foods

Eating a wide variety of nutritious plant foods can provide different types of fiber and nutrients.

Try to regularly include:

• Fruits
• Vegetables
• Whole grains
• Beans and lentils
• Nuts
• Seeds

The World Health Organization recommends a diverse diet that includes foods such as fruits, vegetables, whole grains, legumes, nuts, and other nutritious foods. It also recommends limiting foods high in free sugars, unhealthy fats, and sodium.

See the WHO guidance on healthy diets.

You do not need to change your entire diet at once. Adding a new fruit, vegetable, whole grain, bean, or seed regularly can make your diet more varied.

3. Choose Whole Grains More Often

Whole grains can be an important source of dietary fiber.

Consider choosing:

• Oatmeal
• Brown rice
• Whole-wheat bread
• Whole-grain pasta
• Barley
• Other whole-grain foods

You do not have to completely avoid refined grains. Instead, try making whole grains a regular part of an overall balanced diet.

Whole grains, vegetables, fruits, and pulses are among the carbohydrate-rich foods recommended by the WHO as part of a healthy diet.

4. Include Fermented Foods If You Tolerate Them

Some fermented foods contain live microorganisms. Examples include certain yogurts, kefir, kimchi, and sauerkraut.

However, fermented foods should not be considered a guaranteed treatment for digestive problems. Different products can contain different microorganisms.

It is also important to distinguish fermented foods from probiotic supplements. Probiotics are live microorganisms intended to provide health benefits, but their effects can vary depending on the specific microorganisms and the health condition being studied.

The National Center for Complementary and Integrative Health (NCCIH) notes that researchers are still learning which probiotics may be helpful for specific conditions and which people are most likely to benefit.

If you enjoy fermented foods and tolerate them well, they can be included as part of a varied diet.

5. Drink Enough Fluids

Hydration is important for normal digestion and is particularly useful when increasing your fiber intake.

NIDDK recommends drinking enough liquids to help fiber work better and to help keep stools softer and easier to pass.

Your individual fluid needs can vary depending on factors such as your activity level, health, climate, and diet.

If a healthcare professional has told you to restrict fluids because of a medical condition, follow that advice instead of increasing your fluid intake on your own.

6. Limit Highly Processed Foods

You do not need to completely eliminate processed foods to support a healthy gut. However, frequently choosing foods that are high in free sugars, unhealthy fats, or sodium can make it more difficult to maintain a nutritious overall diet.

The WHO recommends emphasizing a variety of fruits, vegetables, whole grains, legumes, nuts, and other nutritious foods while limiting foods high in unhealthy fats, free sugars, and sodium.

Read the WHO's healthy diet guidance.

Instead of thinking about foods as simply "good" or "bad," focus on the overall pattern of your diet.

7. Stay Physically Active

Gut health is not only about food.

Regular physical activity supports overall health and can also be helpful for people who experience constipation. NIDDK includes regular physical activity among lifestyle measures that may help prevent or relieve constipation.

You do not necessarily need an intense workout. Depending on your fitness level, activities such as:

• Walking
• Cycling
• Swimming
• Dancing
• Strength training

can help you stay active.

If you have been inactive for a long time, start gradually and choose activities that fit your lifestyle.

8. Pay Attention to Foods That Trigger Symptoms

A food that feels comfortable for one person may cause digestive symptoms in another.

Some people notice symptoms such as:

• Bloating
• Abdominal discomfort
• Diarrhea
• Constipation
• Gas

after consuming particular foods or drinks.

A simple food and symptom diary may help you notice patterns. However, avoid unnecessarily eliminating large numbers of foods without professional guidance because restrictive diets can make it harder to get adequate nutrition.

If digestive symptoms are persistent, severe, or interfere with your daily life, speak with a healthcare professional instead of assuming that a particular food is responsible.

9. Be Careful With Probiotic Supplements

Probiotics are often promoted as an easy way to improve gut health, but they are not a universal solution.

Different probiotic products contain different microorganisms, and research does not show that every probiotic works for every digestive condition.

According to NCCIH's information on probiotics, much remains to be learned about which probiotics are useful for specific conditions, which strains work best, and who is most likely to benefit.

Some people may also have a higher risk of complications from probiotics, particularly those with serious underlying health problems or weakened immune systems.

If you are considering a probiotic supplement, discuss it with a healthcare professional first.

10. Make Healthy Habits Consistent

One of the most practical gut health tips is to focus on sustainable habits instead of quick fixes.

You can start by:

1. Adding more vegetables to your meals.
2. Choosing whole grains more often.
3. Eating beans, lentils, nuts, or seeds regularly.
4. Including a wider variety of fruits and vegetables.
5. Drinking enough fluids.
6. Staying physically active.
7. Limiting highly processed foods.

Research supported by NIDDK has found that a diet designed to provide more fiber and other nourishment to the gut microbiome can change the composition and function of gut microorganisms. However, research into the gut microbiome is still developing, and individual responses can vary.

A Simple Gut-Friendly Daily Routine

A practical day might look like this:

Breakfast: Oatmeal with berries and nuts

Lunch: A whole-grain meal with vegetables and beans or another protein source

Snack: Fruit and unsalted nuts

Dinner: Vegetables, whole grains, and a protein-rich food

Throughout the day: Water according to your individual needs

Activity: A walk or another form of regular physical activity

This is only an example. Your nutritional needs may differ based on your age, health, activity level, food preferences, and medical conditions.
