From a Scientific American online release:
One of the immune system’s jobs is to protect us from harmful bacterial. And the beneficial organisms that we refer to as probiotics contribute to this effort in a number of ways. In the gut, a robust population of beneficial bacteria can help crowd out harmful bacteria, making it harder for them to thrive. In addition, probiotic bacteria can influence the activity of our own immune cells, regulating inflammation, barrier function, and cell-to-cell signaling.
One way to foster healthy intestinal bacteria is to eat more of the foods these bugs like to eat—namely, fiber. Increasing your intake of plant fibers from vegetables, fruits, legumes, whole grains, nuts, and seeds is like filling a bird-feeder with the kind of seeds that the beautiful songbirds you want attract like best. If you feed them, they will come!
And if we want to attract a lot of different types of songbirds—er, bacteria—then we want to put out a variety of foods. That means you don’t just want to get all your fiber from a single source, such as a fiber supplement. You want to get it fiber from lots of different kinds of vegetables, fruits, legumes, grains, nuts and seeds.

…the Latin American food and cocktails at Seven Reasons—a mountain of black rice topped with prawns and pork cheeks, a salad in which the summery tang of tomatoes has been concentrated into cubes of jelly, a platter of hamachi tiradito whose pink and green splashes of salmon roe and jalapeño could hang in an art gallery—serve up jubilation as a remedy for pain and color as a cure for the blues. Is there almost too much packed into each bite? No one’s complaining. More-is-more extravagance is what makes Seven Reasons a fiesta you never want to stop.
