The Gut Microbiome: Your Health’s Tiny Powerhouse

Writer: Jacki McEwen-PowellJacki McEwen-Powell

Well now… have you ever wondered what’s really going on inside your gut? Turns out, there’s an entire world of tiny organisms that call your gut home. This community of bacteria, fungi, and even viruses is known as your gut microbiome, and it plays a massive role in your overall health. These microbes don’t just hang out—they help with digestion, keep your immune system in check, and can even affect your mood. Let’s take a closer look at why these little guys are so important and how you can support them.

Gut Microbiome

What is the gut microbiome?


So, what exactly is the gut microbiome? Imagine a bustling city of trillions of microbes living in harmony, all working to keep things running smoothly in your digestive system. Together, they help break down food, absorb nutrients, and even produce certain vitamins that your body needs to function. And it doesn’t stop there—the balance of good and bad bacteria in your microbiome influences everything from your digestion to your mental clarity.


When your microbiome is balanced, you’re likely to feel pretty good. Your digestion is smooth, your immune system is strong, and you’re mentally sharp. But when things get out of whack—like if the bad bacteria start to outnumber the good—you can end up with issues like bloating, fatigue, and even mood swings. This imbalance is called dysbiosis, and it can lead to bigger problems like leaky gut or chronic inflammation.


How to keep your gut microbiome happy


So, how can you keep your microbiome happy? The first step is to feed it right. Think of fibre-rich foods like fruits, vegetables, and whole grains as fuel for the good bacteria in your gut. These foods help beneficial bacteria thrive and crowd out the harmful ones. Probiotics are also key players. These live bacteria, found in foods like yoghurt and kefir, can help replenish and balance your microbiome. And don’t forget prebiotics, the food that feeds your probiotics! Foods like garlic, onions, and asparagus are great prebiotic sources.


It’s not just about what you eat, though. Stress and lack of movement can also throw your microbiome off balance. Chronic stress can increase inflammation and disrupt gut function, so finding ways to manage stress—whether through deep breathing, meditation, or yoga—can go a long way in supporting your microbiome. Staying active is another win for your gut. Regular exercise helps digestion and keeps your microbiome in tip-top shape.


Your gut microbiome may be tiny, but its impact is mighty. By nourishing these little powerhouses with a diverse diet, staying active, and keeping stress in check, you’re setting the foundation for better health.


Taking care of your microbiome is one of the best things you can do for lifelong wellness.


For more tips on supporting your microbiome and taking control of your gut health, check out my books, WELL NOW: Reclaim Your Life from Ulcerative Colitis or Get WELL NOW: Heal Your Gut to Transform Your Life. (Note - these books are the same except for the fact that Get WELL NOW is more focused on general gut health, and WELL NOW is specific to IBD management - you do NOT need both - but you do need one. They also make for great Xmas gifts.
