A guide to good gut health from a nutritionist

Whether it’s the post-meal bloat or feeling backed-up, tummy troubles can *really* wreck your day. Your gut is a lot more than just a place for breaking down food – in fact, good health isn’t possible without a well-running digestive system. By looking after your gut, you’re also looking after your mood, brain, immune, heart, skin health and more.  Here’s 9 ways to keep it in tip-top shape.  

First, why is gut health important? 

Your gut is linked to all kinds of different functions in your body. So when your gut is off, it’s not only your belly that takes the brunt of issues. Think of your gut microbiome as a “gut garden” that hosts trillions of microorganisms like bacteria, fungi and even viruses that influence digestion and other parts of your health. Some of these microorganisms are beneficial and good, while others are bad and can poorly impact your health. Ensuring you have a healthy ratio of the good and bad can influence your overall wellness.  

1. Eat fermented foods 

One way to encourage good gut health is to add fermented foods into your diet. The good bacteria that naturally live in your gut are also found in foods like: yogurt, kimchi, kombucha, sauerkraut and miso. Adding these foods regularly into your diet can boost the number of these beneficial bacteria and strengthen your gut microbiome.  

2. Consider a probiotic  

If fermented foods aren’t your favorite – try a daily probiotic instead. Probiotic supplements contain beneficial, living microorganisms like the ones in your gut and in fermented foods. Probiotics can help rebalance and reshape your microbiome. There’s different strains of probiotics that offer different benefits to your health – some support your gut intestinal barrier and skin health1, some mood and stress2, while others promote immune health.* So it’s best to identify what areas of support you need when starting a new probiotic supplement. (Here’s a full guide on probiotics from our dietitian.)  

3. Focus on fiber  

Fiber is an indigestible type of carbohydrate, meaning your body can’t fully break it down. It’s naturally found in fruits, vegetables, nuts, seeds, beans and grains. So while filling half your plate with greens might not be the best part of your meal, it does help protect the mucus layer in your digestive tract and adds bulk to help keep things moving along.3  

Plus, fiber is often referred to as prebiotics – it ferments in your digestive tract and feeds the probiotics (good bacteria) to stimulate their growth to promote a healthy digestive tract and supports your body to absorb certain nutrients according to a study!4  

4. Up the fruits and veggies  

Fruits and veggies are not only naturally high in good-for-you-gut fiber, but they also contain substances called polyphenols, which give them their vibrant color and taste. A reason kale or berries are seen as superfoods – the brighter their color, the more polyphenols they offer. Polyphenols increase the presence of several strains of good bacteria to support the overall health of your gut5. So while iceberg lettuce might have a milder taste – next time try mixing half your salad with some spinach or kale for the gut-boosting benefits. 

5. Moderate your (red) meat intake  

Sorry to all the enthusiastic carnivores, this one’s directed at you. In addition to lacking fiber and those gut-loving polyphenols, red meat can be high in saturated fat, which is tough on your gut and your heart. Too much red meat can reduce good bacteria that aid in metabolism, while increasing bad bacteria that have harmful effects on health6. Not just that, but a diet too high in red meat may also be linked to higher rates of intestinal inflammation7. But that doesn’t mean you can’t enjoy your favorite cut of steak – just eat it in moderation and balance it with other healthy options.  

6. Limit alcohol   

It’s not just your liver that takes a hit from those happy hour drinks. Alcohol is absorbed in your small intestine, and while a drink here and there isn’t bad for most, too many drinks can affect the integrity of the protective mucus layer in your gut8. This not only disrupts the balance of good and bad bacteria in your digestive tract but can also lead to inflammation and poor absorption of vital nutrients. It’s best to limit to one-drink a day for women and two for men

7. Cut down on sugar  

You’re probably already aware of some of the effects too much refined sugar can have on your body. What’s surprising is that too much sugar can also cause an imbalance of gut bacteria. Sugar feeds and promotes harmful microbes, increasing bad bacteria and reducing good bacteria. This imbalance of microbes may lead to inflammation and affect the lining of your intestine9 leading to a list of annoying symptoms. Think: poor mood, energy, skin and hormone health. Like everything else, eating a piece of cake or candy once in awhile won’t harm your gut – but it’s better to opt for natural sweet foods like fruit to satisfy those cravings. 

8. Manage stress 

Stress impacts all parts of your body, including your gut. When times are tough, your body releases stress hormones, like cortisol. If left unchecked, cortisol can disrupt your gut microbiome, which can lead to a slew of unwanted symptoms like poor mood, brain fog, compromised immune health and more.  Although you may not be able to control all the curveballs life throws your way, it’s best to find ways to help cope and manage stress. Walking outside, journaling, reading a book or meditating are all good methods to help with calming and relaxation.   

9. Be mindful of your antibiotic use 

Antibiotics are a lifesaving advancement in modern medicine that completely changed how bacterial infections are treated, but they’re not free of caveats. You’re probably familiar with these drawbacks if you’ve ever had to make a frantic run to the restroom after being treated for an infection! This is because antibiotics work by killing harmful bacteria, but in the process, they also get rid of good bacteria.10 If you do have to do a round of antibiotics, it’s best to discuss with your healthcare provider if starting probiotic supplementation is a good option to help negate some of the negative effects.
