8 Steps to a Healthier Gut—and a Longer, Healthier Life

Once upon a time it was thought that the health of our gut was only dictated by what we ate and that any problems originating in the gut stayed in the gut. Fast forward to today where research has shown that those two ideas are almost completely inaccurate. Not only is our digestive system far more complex than once understood, but we now know that there are many factors beyond diet that profoundly affect our gut health; and because the gut plays a central role in immune function, metabolism, hormone regulation, and even brain health, its balance is directly tied to our long-term vitality. In other words, a healthy gut is not just about feeling better today—it’s one of the most important investments we can make in our future well-being.

The gut microbiome is made up of trillions of tiny microorganisms. When the gut becomes unbalanced and harmful bacteria outnumber beneficial strains, it can trigger a cascade of health issues throughout the body. Key factors that influence the make up of our microbiome include diet, sleep, stress, medications, environmental exposures, and lifestyle.

Digestive symptoms such as gas and bloating may be the first warning signs of an imbalance, but when left unaddressed, other more serious conditions can manifest—such as autoimmune disorders, mood disorders, chronic joint and muscle pain, or cardiovascular disease. By restoring and nurturing a healthy balance of gut bacteria, we not only see an improvement of symptoms, but we enhance immune resilience, emotional well-being, metabolic function, and digestion—all essential pillars of healthy aging and key contributors to long-term vitality and longevity.

Restoring gut balance

1. Increase your fiber intake

A simple but effective step. Nutrition experts say adults should consume at least 25 grams of fiber each day for regulating digestion (it’s thought that most Americans eat only 16 grams a day on average).  Fiber also acts as a prebiotic, serving as a food source for many strains of beneficial gut bacteria. Apples, avocados, bananas, potatoes, lentils, and oats are just a few examples of fiber-rich foods.

2. Consider gut-friendly diets: Low-FODMAP diet

Common diets for individuals with conditions like Irritable Bowel Syndrome (IBS) include the low-FODMAP diet, a specific carbohydrate exclusion diet. Those with IBS may experience symptoms such as cramping, diarrhea or bloating after consuming certain carbohydrates that are hard to digest; the low-FODMAP diet eliminates these carbohydrates. A 2017 study in the Journal Gastroenterology & Hepatology reviewed existing research and found that 50% to 86% of people with IBS responded well to a low-FODMAP diet.

However, before starting any gut-friendly diet, it is important to remember that diets like FODMAP come with mixed results. They work well for some individuals while having no impact on others. It is always advised to speak to a physician or nutritionist about any major changes to your diet.

3. Stay active

Regular exercise has positive effects on the gut microbiome. Whether it’s running, walking, yoga or going to the gym, any exercise is good. Recent studies suggest that exercise can enhance the number of good bacteria in the gut.

4. Add food diversity to your diet

A healthy microbiome is one that’s diverse. That means the microbiome is populated with a range of food items: asparagus, artichokes, radishes, leeks, and particularly fermented foods like:  sauerkraut, kefir, kimchi and miso. A 2016 study in the Journal Molecular Metabolism notes that the more diverse the diet, the more diverse the microbiome and the more adaptable it will be to changes.

5. Dealing with stress? Consider cognitive behaviour therapy

The term “butterflies in your stomach” refers to having a nervous feeling in the stomach during certain situations. Although it’s not meant to be taken literally, there is a lot of truth to the statement as it links our feelings to digestion. Anger, anxiety, sadness — all of these feelings (and others) can trigger symptoms in the gut. This is where Cognitive Behavioral Therapy (CBT) might help. CBT is one of the most common forms of psychotherapy. It is a form of talk therapy that explores the way that your thoughts and emotions impact your behavior and health. The therapy can help teach relaxation to reduce stress, and promote relaxation which can in turn reduce gut symptoms.

6. Limit the amount of processed food you eat

Highly processed foods can throw the microbiome off balance. Replace canned foods, soft drinks and packaged snack foods with natural, whole foods.

7. Probiotics

Early studies have suggested that imbalances in intestinal bacteria can cause “arthritis, diarrhea, autoimmune illness, B12 deficiency, chronic fatigue syndrome.” Probiotics may help correct that imbalance. Probiotics are defined as live microorganisms that may have health benefits when consumed or applied to the body. While this is still an emerging field of study, researchers have found that certain strains of probiotics can help reduce inflammation in people with certain diseases. You can find probiotics in yogurt and fermented foods.

8. Cut back on NSAIDs.

Regular use of non-steroidal anti-inflammatory drugs medications (NSAIDs) such as Ibuprofen or Aspirin can cause a massive disruption of the gut flora. NSAIDs simultaneously reduce pain and prevent healing, and because the lining of the intestines is repaired and replaced every 3 to 5 days, the mechanism of NSAIDs dangerously interrupts and blocks that process.

By incorporating some of the simple daily practices mentioned above, you can restore microbial balance to your gut and strengthen the foundations of lifelong vitality. A healthier gut today truly sets the stage for healthier aging tomorrow!
