Seen the headlines? We are not alone!
We share our bodies with trillions of microbes. The majority live in our guts, and these tiny critters play a key role in keeping us healthy.
Science is still piecing it all together. But the initial insights are intriguing. Our gut microbes fight off intruders, help digest food, make vitamins, prep and protect our immune systems, and more.
Taking care of our microbes helps them take care of us. We can start by being good hosts: feeding our friendly microbial guests what they’re hungry for. Here are 8 ways to eat for a healthy gut!
1. Eat a Wide Variety of Plants, Fruits, and Veggies
Sound familiar? There’s really nothing new about this advice. Just like their human hosts, the beneficial bacteria that make up our microbiome thrive on a diversity of fiber-rich plants and fruits. So go big on bananas, beans, onions, leeks, oats, whole grains, nuts, avocados, leafy greens, broccoli, asparagus; and fermented foods like yogurt, kimchi, and sauerkraut. The key is variety because it seems that different types of fiber benefit certain bacteria, which in turn benefit the body in specific ways.

2. Don’t Overcook the Veggies
Soft, overcooked veggies are quickly digested. Leave a little crunch, and the microbes down the line have more to munch on.

3. Chomp on More of the Plant
Eat further down the veggie stalks and stems, not just the soft tips and florets. Your gut will thank you.

4. Eat Fermented and Cultured Foods
Enjoy yogurt for breakfast, a little sauerkraut on sandwiches and salads for lunch, and this homemade kimchi with grilled or roasted meats.
5. Give an A+ to Artichokes, Asparagus, and Avocados
These fiber-rich foods earn top marks. Also, don't forget about Jerusalem artichokes. Full Disclosure: Jerusalem artichokes are not really from Jerusalem; they're not even artichokes. But despite the fibs, the truth is, they’re among the gut-friendliest of foods.

6. Be Keen for Greens
Your good bacteria love the fiber in kale, spinach, bok choy, and other leafy greens.

7. Seek Out Leeks
Leeks are legendary for helping promote good gut health. Watch Chef John make his simple Sexy Fish Stew with lots of leeks, shallots, and fennel bulbs.
8. And, Finally, a Word About Kraut
Sauerkraut's not just for hot dogs. Sneak this fabulous fermented food into summer salads and stir-fries, and onto sandwiches, pork chops, even your scrambled eggs.

Why is dietary fiber good for us? As we've said, when we eat dietary fiber, we’re feeding the critters in our guts. The billions of bacteria benefit first by feeding on the fiber that’s indigestible to humans. Healthy gut microbes lead to a healthier gut, which translates to a healthier immune system. Also, after the bacteria in the gut break down the fiber, they leave behind short-chain fatty acids, which keep the cells of the intestines healthy and may help calm aggressive immune system responses. Diets rich in dietary fiber may also help defeat obesity and reduce the risk of heart disease, diabetes, along with immune disorders like irritable bowel syndrome.
