Feed your Microbiome!
Our intestines contain a variety of beneficial bacteria that are closely associated with our health and immune system. Healthy adults typically harbor more than 1000 different species of bacteria in our gut microbiome. These different species respond to what we eat. By focusing on feeding our microbiome we can create an internal balance to help our body absorb nutrients and help keep our immune system in fighting shape!
Your gut is home to trillions of microorganisms—collectively known as the gut microbiome—that play a vital role in digestion, immunity, mood regulation, and overall health. These microbes thrive on what you eat, making your daily food choices one of the most powerful tools for supporting a balanced and diverse microbiome.
Feeding your gut means nourishing these beneficial bacteria with fiber-rich, plant-based foods like fruits, vegetables, legumes, whole grains, nuts, and seeds. These foods contain prebiotics—non-digestible fibers that act as fuel for healthy gut bacteria. Fermented foods like yogurt, kefir, sauerkraut, kimchi, and miso also introduce probiotics, or live beneficial bacteria, that can help maintain microbial balance.
A well-fed microbiome contributes to better digestion, reduced inflammation, improved mental clarity, and even stronger immunity. On the other hand, diets high in processed foods, sugar, and artificial additives can disrupt this delicate ecosystem, leading to bloating, fatigue, and long-term health issues.
By making mindful, gut-friendly food choices, you’re not just feeding yourself—you’re feeding a complex internal community that supports your well-being from the inside out.
How can we feed and nourish these bacteria?
Prebiotics and probiotics are a great place to start! Probiotics are live beneficial bacteria, and are found in foods such as Greek yogurt, kefir, and fermented products like kimchi, unpasteurized pickles, and unpasteurized sauerkraut. Consuming probiotics is particularly important during antibiotic treatments, as they can prevent and reduce antibiotic-associated diarrhea . Prebiotics are complex carbohydrates that provide food for our gut bacteria, and are found in foods such as beans, legumes, oats, bananas, berries, onions, broccoli and cabbage.
Try to incorporate prebiotics and probiotics into your daily eating plan to nourish your microbiome!
