How to Build a Supergut

Eat an abundance of prebiotic-rich foods, like onions,
garlic, and leeks.
Open your windows, since soil blowing in dirties up
the sterile indoors. Better yet, go to parks more or
exercise outside.
Adopt a dog. A recent study in the journal PLOS One
found that homes with dogs had more diverse microbes.
Get your hands dirty in the garden. The microorganisms
in soil enhance your own inner terrarium.
Cook veggies al dente. "Your body has to work harder
to break them down, so more end up in your colon,"
says American Gut Project cofounder Jeff Leach.
Diversify your plate. Instead of a big pile of spinach, grab
a little bit of everything at the salad bar. The fiber is very
different in different vegetables.
