The Microbiome Makeover: Conditioning Your Gut for a Healthier You
Every human body is a host to trillions of bacteria, viruses, and other microscopic organisms that live symbiotically within our intestines.1 This community of tiny denizens is called the gut microbiome. Scientists have learned that some of these little guys naturally support immunity, crowding out potentially harmful microbes before they can invade our bodies.2
Sometimes we have trouble maintaining a healthy microbiome balance. Here are a few tips to help keep you on track, to keep you feeling your best.
Eat Foods Rich in Prebiotics
It makes sense that one of the best-known ways to care for our gut microbiome is with the food we put into our gut. Prebiotics are foods that are high in special types of fiber humans can’t digest, but that the gut microbes in our intestines use as food.[3,4]
Prebiotics are generally plant foods. Providing nutrition for your gut microbiome is a great reason to choose a plant-based diet. These foods include:[3.4]
Vegetables like asparagus, broccoli, cabbage, Jerusalem artichokes, jicama, kale, and onions.
Fruit like apples, bananas, kiwifruit, and pomegranates.
Whole grains like barley, oats, rice, and whole wheat.
Nuts and seeds like almonds, flaxseed, pistachios, and walnuts.
Eat Fermented Foods
Some foods have helpful active and live microbial cultures already in them. Fermentation is the process of adding living microbes to certain foods, changing the foods into something new. For example, yogurt is made by adding lactic acid bacteria to milk.5
Almost every ancient culture has made and consumed their own version of fermented food for thousands of years. Some of the living microbes within these delicacies make their way to our intestines after we eat them, improving the microbiome population.5
Some examples of fermented foods include:5
Kefir, or fermented milk.
Yogurt, which is also fermented milk.
Miso, or fermented soy paste.
Sauerkraut, or fermented cabbage.
Kimchi, generally a combination of fermented chili peppers, garlic, and other vegetables.
Tempeh, or fermented soybeans.
Physical Activity also seems to have a positive impact on microbiome health, especially for people who choose low to moderate intensity aerobic exercise.[6,7,8] This includes activities like:
Easy bike riding
Fast walking or light jogging
Swimming and water aerobics
Scientists aren’t sure why exercise helps, but one reason may be because the movement speeds digestion time, allowing less time for harmful bacteria to take up residence in the intestines. This allows the friendly bacteria to maintain a robust population.[6,7,8]
Spend Time in Nature
Microorganisms in our intestines aren’t the only part of our microbiome that may contribute to good health. Researchers are also looking at the balance of microbes on our skin, in our mouths and within our respiratory tract and their positive impact on seasonal sensitivities and oral health.9
Some research shows that rural living and getting outdoors in nature may increase the diversity of our overall microbe population. Consider activities like walking out in nature, hiking in the woods, and vegetable or flower gardening and getting your hands in the soil.[9,10]
Find Out What You’re Missing
Probiotics supplements may be helpful for some people having trouble maintaining a microbiome balance. Unfortunately, there’s no way to know which supplements are best for any person without careful testing. Simple blood and fecal tests could determine which supplements may be best for an individual.
By eating the right foods, exercising regularly, enjoying outdoor activities, and supplementing when recommended, you can work toward maintaining a healthy balance in your gut microbiome.
