Feed Your Gut

Good for Your Gut

If you’ve ever had the gut feeling that there’s more to eating well than counting calories and watching your cholesterol then you really should trust your gut. Research on the world within our intestinal tract shows that the mixture of microbes in the gut can make or break the body’s overall health. Referred to as the microbiome, the population of friendly bacteria that live in the gut aid digestion, help absorption of nutrients and boost immune function. “It’s the control center for human biology,” said Justin Sonnenburg, PhD co-author of The Good Gut and researcher at Stanford University’s School of Medicine. Sonnenburg and co-author wife Erica, also at Stanford, are leading the charge to place the microbiome at the center of the discussion about optimal health today. “We have more bacteria than cells in our bodies. We are more microbial than we are human,” said Justin Sonnenburg.

So what does a good gut look like? According to the Sonnenburgs and other researchers focused on intestinal health the quantity and variety of bacteria is key.

A poor diet lacking dietary fiber can wreck the microbiome’s health because fiber is what they feed on. Fiber in plant foods is considered a ‘prebiotic’ because it’s the preferred food for intestinal bacteria.

 

When they don’t get their ‘food’ from what we consume the bacteria can eat away at the mucosal lining of the intestinal tract and eventually perish. “Low fiber intake leads to reduced bacterial diversity in the gut,” said Erica Sonneburg. “It’s diet-induced extinction of the gut bacteria.”

The average American consumes about 15 grams of dietary fiber a day. The recommended amount for good health is between 25 and 35 grams per day.

“You have to feed your bugs, not just your body,” said registered dietitian Regan Miller Jones. “It’s yet another reason to eat more vegetables and whole grains.”

Fermented dairy foods such as yogurt and kefir with live active cultures as well as fermented vegetables such as sauerkraut and kimchi help add good bacteria to the gut so are called ‘probiotic.’

“There’s an explosion of probiotics foods and beverages in the dairy aisle with beneficial live microbes,” said Erica Sonnenberg. “But keep in mind that probiotic supplement pills are unregulated and are often mislabeled. And what might work for one person might not work for others. It’s highly personalized.”

Another note of caution for fans of ‘detox’ regimens including colonics that ‘flush out’ the GI tract. Justin Sonnenberg said, “Colonic irrigation is not safe or effective for the health of the microbiome.”
