Trim Your Gut's Holiday Woes:
Nowadays, we've started seeing the trillions of microorganisms that colonize our bodies as more than just unwanted passengers. Our gut microbiota plays a vital role in our health, so it's crucial to keep these tiny partners in crime happy, especially during holiday season marked by calorific excesses.
A research team from the Lee Kong Chian School of Medicine in the Nanyang Technological University in Singapore, led by Dr. Sven Pettersson, reported in the journal Cell that our gut microbiome naturally evolves throughout our lifetime. In the beginning, we have a simple collection of a handful of bacteria, which matures into a complex microbial ecosystem due to factors such as our diet, lifestyle, hormones, and immune system.
Unfortunately, imbalances in our gut flora are connected to a steady rise in conditions like food allergy, eczema, asthma, autism spectrum disorders, chronic fatigue syndrome, irritable bowel syndrome, and even cancer. As the year ends and we wind down, let's look at what we can do to care for our gut microbes.
1. Stock Up on Fiber
Even though we can't digest fiber ourselves, microorganisms can utilize it as a food source. If there isn't enough fiber in our diet, microbes start munching away on the mucus barrier in our gut as an alternative food source, making the gut "leaky" and opening the door for harmful bacteria to enter, thus causing inflammation and potentially harmful health conditions.
Two research groups reported in the journal Cell Host & Microbe what happens when we switch to a Western-style diet, which is low in fiber, even for a short period time. Within just 3-7 days, mice fed a low-fiber diet began showing signs of a leaky gut, weight gain, high blood sugar, and insulin resistance. This was accompanied by widespread bacterial death in the gut, which resulted in the unchecked growth of certain unfavorable bacteria like Bacteroides and Actinobacteria. Professor Gunnar C. Hansson, the co-author of the study, explained that diets lacking fiber alter bacterial composition and metabolism, ultimately causing issues with the inner mucus layer and allowing bacteria to encroach, leading to inflammation and metabolic disease.
Rebuild with Fiber
The good news is, adding bacteria that break down fiber, such as Bifidobacterium, to the diet could improve gut health, according to Prof. Hansson and colleagues. Inulin, a type of prebiotic plant fiber, was also shown to have Restorative effects on gut health. However, before you start loading up on inulin to counteract your holiday overindulgence, Professor Gewirtz of Georgia State University cautions: "Simply enriching processed food with purified fibers may provide some health benefits, but we're not ready to recommend it until we understand more about the complex interplay between food, bacteria, and the host."
Instead, choose holiday foods that naturally pack a fiber punch. The American Heart Association provides some recommendations for fiber-rich holiday foods.
2. Dip Your Tooth into Chocolate
Rich in antioxidants and fiber, cocoa has been linked to various health benefits, including reducing cholesterol and improving fetal development during pregnancy. When it comes to our gut health, cocoa consumption can help reduce inflammation, which might alleviate symptoms of inflammatory bowel diseases such as Crohn's and ulcerative colitis.
In another study, cocoa components were found to reduce bacteria in the Clostridium family, which are often found in the guts of those with IBD. When human study subjects drank high-cocoa chocolate milk over a period of 4 weeks, Lactobacillus and Bifidobacterium species increased in their guts.
Be aware that not all chocolate is created equal. Unsweetened cocoa powder and dark chocolate with a high cocoa content are the closest you can get to the cocoa formulations used in scientific research. So, why not indulge in a piece or two of dark chocolate during the season of gift-giving and treats?
3. Work Off Your Holiday Calories
Two recently published studies showed the power of exercise: it can directly impact the diversity of your gut microbiome. One study on mice demonstrated that active mice had a greater abundance of bacteria that can metabolize fiber into beneficial short-chain fatty acids (SCFAs), which contribute to overall health. Human study participants experienced an increase in SCFA levels and SCFA-producing microbes after just 6 weeks of exercise, though this increase was more pronounced in lean individuals. However, remain motivated by the benefits that exercise can provide to your gut health regardless of your body composition.
4. Keep Stress at Bay
It's easier said than done, but it's crucial to manage stress during the holiday season, as excessive stress can negatively affect the gut microbiome[1][2]. If you feel overwhelmed, refer to our guide on "Managing Holiday Stress" for practical tips to help you wind down and relax.
A New Year and a Healthy Gut
These strategies, backed by recent scientific research, will help ensure that your gut microbes survive the holiday season and kick off the new year in tip-top shape.
Next year may bring even more insights into how our microbiome shapes our health and what we can do to help maintain our gut in a healthier state.

A healthy gut is also about nourishing it with the right nutrients. In addition to dietary fiber, probiotics found in fermented foods like yogurt, kefir, sauerkraut, kimchi, and kombucha can help promote beneficial bacteria in the gut[5]. Adequate sleep, hydration, and managing environmental toxins are also essential for maintaining a healthy gut[2][3]. Stress management can help maintain gut health as well, through relaxation techniques like meditation or yoga[1]. Prioritizing these wellness strategies can support overall health, ultimately contributing to a healthier gut microbiota.
- A healthy digestive system relies greatly on our food choices, particularly the consumption of fiber, as it serves as a great food source for microorganisms in our gut.
- The food we eat, along with our lifestyle, hormones, and immune system, significantly impact the microbiome in our gut, which is increasingly recognized for its vital role in overall health.
- Imbalances in the gut microbiome have been linked to numerous health issues, including food allergies, eczema, asthma, autism spectrum disorders, chronic fatigue syndrome, irritable bowel syndrome, and even cancer.
- Research has shown that switching to a Western-style diet, which is low in fiber, can lead to a leaky gut, weight gain, high blood sugar, insulin resistance, and widespread bacterial death in the gut within just a few days.
- Adding bacteria that break down fiber, such as Bifidobacterium, to our diet, or consuming prebiotic plant fiber like inulin, could potentially improve gut health.
- Incorporating foods rich in fiber, such as holiday foods recommended by the American Heart Association, can help rebuild a healthy gut and combat the effects of overindulgence during the holiday season.
- Engaging in fitness-and-exercise activities and managing mental-health stress during the holiday season can also positively impact the diversity of the gut microbiome and contribute to overall health-and-wellness.
