Yes, the Gut Is Important—But So Is Your Whole-Body Health.
If you’ve been paying attention to the latest health trends, you’ve probably heard a lot about the microbiome. And for good reason! We’re learning just how important gut health is—it influences digestion, immunity, and even brain function. But let’s not get tunnel vision.
The gut doesn’t work in isolation. Your microbiome is just one piece of the bigger picture. Your overall health is what truly matters. If you eat a truly health-promoting diet, your microbiome naturally thrives—along with your brain, immune system, and every other part of your body.
Focusing only on gut bacteria while neglecting the rest of your health is like worrying about the quality of your tires while ignoring the engine, fuel, and maintenance of your car. If you take care of your body, your gut will take care of itself.
However, there are important tips to remember when nuturing your gut. Tune into the Eat to Live Podcast to uncover the lastest about your microbiome and gut health.

What Is the Microbiome?
Your microbiome is made up of trillions of bacteria living in your gut—both beneficial and harmful. The key to a healthy microbiome isn’t about taking probiotic supplements or eating fermented foods. It’s about ensuring the good bacteria thrive, while preventing harmful bacteria from taking over.
Think of it like a well-maintained garden. If you plant strong, dense vegetation, weeds don’t stand a chance. But if you leave bare patches of soil, invasive species can take over. The same happens in your gut. A diverse diet rich in plant fibers fosters a strong, diverse microbiome that naturally keeps harmful bacteria in check.
The Best Way to Support Your Microbiome
Forget the yogurt, kimchi, and probiotic pills—science has moved beyond that. The healthiest microbiomes belong to people who eat the most varied plant-based diets. The key is diversity:
Eat a wide variety of vegetables—not just romaine, but arugula, kale, bok choy, and microgreens.
Rotate your mushrooms—button mushrooms are fine, but shiitake, maitake, and lion’s mane offer unique health benefits.
Choose different beans and legumes—black lentils, chickpeas, azuki beans, and black beans all help nourish beneficial bacteria.
Mix up your nuts and seeds—almonds, walnuts, flaxseeds, and hemp seeds provide different types of fibers and polyphenols that promote gut health.
Each type of plant fiber feeds a different species of beneficial bacteria. The more diverse your plant intake, the stronger your microbiome becomes, and the better it supports your immune system, digestion, and overall health.
Why Green Vegetables Are Essential
Your gut health is directly linked to your immune system—70% of your immune cells are located in your gut lining. And what fuels these immune defenses? Green vegetables.
Leafy greens provide:
✔ Sulfoquinovose, a unique carbohydrate that fuels beneficial gut bacteria.
✔ Prebiotic fiber, which helps bacteria produce short-chain fatty acids that lower inflammation.
✔ Compounds that strengthen gut lining, preventing leaky gut and food sensitivities.
Without a high intake of green vegetables, your gut lining weakens, leading to inflammation, poor digestion, and increased susceptibility to infections.
Bloating? Indigestion? Fix It Naturally
If you struggle with bloating or poor digestion, you might be tempted to avoid fiber-rich foods. But that’s the opposite of what you should do! Instead of eliminating beans and cruciferous vegetables, slowly introduce them into your diet in small amounts to help your body adjust.
Start with:
A tablespoon of beans per meal, gradually increasing over time.
Lightly cooked greens if raw vegetables are too harsh at first.
Cold, pre-cooked potatoes, which contain resistant starch that feeds healthy gut bacteria.
And chew your food well! Chewing releases enzymes that aid digestion, fuels beneficial bacteria, and even strengthens your teeth and gums.
The #1 Diet for a Healthy Microbiome
A microbiome-friendly diet isn’t just about avoiding junk—it’s about maximizing nutrient density and variety. That’s why the Nutritarian diet is the most effective way to build a healthy gut. It emphasizes:
G-BOMBS (Greens, Beans, Onions, Mushrooms, Berries, and Seeds)—foods proven to enhance gut and immune health.
No refined flour or processed sugar, which feed harmful gut bacteria.
No inflammatory oils, which damage the gut lining.
A diversity of plant foods, ensuring your microbiome gets all the nutrients it needs.
The Bottom Line
Yes, your microbiome is incredibly important, but so is your whole-body health. Instead of fixating on probiotics, gut tests, or fermented foods, focus on nutrient-rich eating. When you optimize your diet, your microbiome will thrive—along with the rest of your body.
Eat a large salad every day. Incorporate a variety of greens, onions, sprouts, beans, and nuts. Chew your food thoroughly. Avoid white flour, sugar, and processed foods that destroy gut health.
Your gut isn’t an isolated system—it’s part of the greater symphony of your body. Take care of your whole health, and your microbiome will thrive naturally.
