The human microbiome is a fascinating ecosystem composed of trillions of microbes. Throughout this article, we will explore the microbiome, what it does, and what it needs to thrive.
I recently finished the book Fiber Fueled by Dr. Will Bulsiewicz, which discusses the importance of a plant-based diet for your microbiome health. He also discusses the importance of having a well-nourished microbiome.
What is the gut microbiome?
In the digestive tract, there is a complex ecosystem of microorganisms known as the gut microbiome. The microbiome consists of bacteria, fungi, and viruses, and it plays a vital role in maintaining our overall health.
“The human gut is all interconnected in a way that draws direct comparisons to planet earth. Your gut microbiome is just as much of an ecosystem as the amazon rainforest. It thrives on balance and harmony.”
Your microbiome's purpose
The microbiome regulates hormones, supports the immune system, and reduces inflammation in the body. It also helps to regulate digestion and metabolism, and it is thought to be linked to mental health and well-being. In fact, 90% of serotonin and 50% of dopamine are produced in the gut, as well as 30 other neurotransmitters.
“With the gut acting as a home base for these neurotransmitters, you can see how mental health conditions like depression and anxiety emerge when there’s a problem in the gut”
Feeding your microbiome
To maintain a healthy gut microbiome, it is essential to consume fiber. Adding fiber to your diet can help to maintain a healthy balance of bacteria in the gut. Fiber can be found in fruits, vegetables, nuts, seeds, and whole grains. Fermented foods like sauerkraut and kimchi can also provide fiber and beneficial bacteria.
Additionally, it is important to avoid certain foods as well. Reducing consumption of highly processed and refined foods, saturated and trans fats, sugar and artificial sweeteners, and alcohol will help support a healthy microbiome. These items can adversely affect a microbiome's balance of beneficial and harmful bacteria.
