Happiness and Gut Health: How Your Amazing “Second Brain” Influences Mood, Performance, and Well-Being
Part 3 of our Three-Part Series on Happiness
This third article in our Happiness Series concentrates on the often-overlooked role of gut health in overall well-being. Specifically, we explore the gut microbiome—an intricate community of trillions of microorganisms residing in our digestive tract. These microbes outnumber human cells by an astonishing 10 to 1 ratio, influencing digestion, brain function, immunity, and other biological processes.
The Gut-Brain Connection
Often called the “second brain,” the gut contains an extensive network of nerve endings and produces over 90% of the body’s serotonin, a key neurotransmitter in affecting mood and cognition. The gut and the brain communicate extensively, in large part via the vagus nerve, an arrangement termed the gut-brain axis.
Importance of a Healthy Microbiome
The microbiome consists of bacteria, fungi, and viruses that coat the gut lining. A healthy microbiome—rich in diversity and favorable bacteria—is essential for digestion, nutrient absorption, and mood regulation. It also influences overall health through nerve signaling, hormones, and immune responses.
Dysbiosis
Dysbiosis, or an unhealthy microbiome—an increasingly common condition—can result from diets high in sugar and highly processed foods, antibiotic overuse, and chronic stress. It can lead to digestive discomfort, bad breath, skin conditions, mood disturbances, and cognitive decline. Additionally, dysbiosis is linked to chronic inflammation, which is associated with autoimmune disorders, cardiovascular disease, dementia, chronic pain, and even some cancers.
Impact on Physical Performance
A healthy gut enhances physical performance by optimizing nutrient absorption and metabolism, boosting energy levels and endurance. It also helps reduce systemic inflammation, promoting faster muscle recovery. Likewise, regular moderate exercise—especially outdoor activities like cross-country skiing and snowshoeing—lowers cortisol levels, fostering a balanced gut microbiome. This creates a virtuous cycle in which gut health improves physical performance, while physical activity, in turn, supports gut health.
Feeding the Microbiome
Maintaining gut health requires mindful nutrition. A gut-friendly diet includes prebiotic and probiotic-rich foods, fiber, anti-inflammatory omega-3s, good fats, and plant-based polyphenols. Beans are a microbiome superfood, rich in many of these nutrients, as well as protein, vitamins and minerals. They offer great nutritional value for the cost and should be a staple in your pantry.
The Four F’s for Gut Health:
- Fermented Foods: Add yogurt, kefir, sauerkraut, and kimchi to your daily diet.
- Fiber: Incorporate beans, oatmeal, nuts, seeds, and whole grains into meals.
- Phenols: Consume a variety of fruits, vegetables, herbs, and spices daily.
- Fats: Choose healthy fats like extra virgin olive oil and avocado oil; include fatty fish if part of your diet.
Conclusion
Gut health is fundamental to both emotional and physical well-being. By making simple dietary changes—specifically replacing highly processed and sugary foods with the four F’s—you can improve your microbiome in a short period of time. As a result, you may experience increased stamina, reduced pain, and enhanced mood and cognition.

Personal Recommendations: The Northwind Co-op in Ironwood is an excellent source for gut-friendly groceries. Some of our favorites include the variety of bulk beans, whole grains, nuts, and seeds. We also love the fermented foods from Spirit Creek Farm in Northern Minnesota and locally grown micro-greens from Superior Sprouts a great year-round source of fresh greens.
From June until October, the Ironwood Farmers Market offers locally grown produce. If you are not local to Ironwood, look for local farmers markets and co-op stores nearby.
For creative ideas about adding beans to your diet, this site is our recent obsession: Rancho Gordo Recipes.
