The microbiome is the trillions of organisms that live in our intestines and digest our food, create many of our vitamins, etc.
And if it gets injured, as in leaky gut, wipe-out of organisms, we can suffer. Learn what's going on in there and how to heal gut problems. As usual, a stellar cast of speakers.

- As Robin's link, scrolled down, still connects to great resources and connection to speakers' websites and more articles even long after the summit, I'll add to that for a sort of
. . . Brito sought to understand not only how bacteria move between human communities but also how genes move between bacterial communities.
Unlike most human cells, bacteria have a flexible genome, meaning that they can pick up stretches of genetic material from viruses, other bacteria, or dustings of DNA in their immediate environment. . . .
. . . “Our microbiome needs to be fed to stay alive and is at the mercy of what we ingest on a daily basis,” Gautam Dantas, a microbiologist at Washington University in St. Louis, told me. . . . -

Is The Secret To A Healthier Microbiome Hidden In The Hadza Diet?
By Michaeleen Doucleff - NPR - August 24, 2017
Excerpts:
. . . For the past few years, scientists around the world have been accumulating evidence that the Western lifestyle is altering our microbiome. Some species of bacteria are even disappearing to undetectable levels. . . .
. . . The study, published Thursday in the journal Science, focuses on a group of hunter-gatherers in Tanzania, called Hadza.
Their diet consists almost entirely of food they find in the forest, including wild berries, fiber-rich tubers, honey and wild meat. They basically eat no processed food — or even food that comes from farms. . . .
. . . But then in wet season — when Hadza eat more berries and honey — these missing microbes returned, although the researchers are not really sure what's in these foods that bring the microbes back. . . .
. . . "because what changed in the Hadza's diet was whether or not they were hunting versus foraging for berries or honey," he says.
But Sonnenburg is placing his bets on another dietary component: fiber — which is a vital food for the microbiome.
"We're beginning to realize that people who eat more dietary fiber are actually feeding their gut microbiome," Sonnenburg says.
Hadza consume a huge amount of fiber because throughout the year, they eat fiber-rich tubers and fruit from baobab trees. These staples give them about 100 to 150 grams of fiber each day.
That's equivalent to the fiber in 50 bowls of Cheerios — and 10 times more than many Americans eat. . . .
[Poster's note, though, processed breakfast cereal is not a good option, ever, really and the author is not saying it is - just comparing an average US diet to others.
Processed cereal is not whole food. Best fiber is from a variety of plants, grains and seeds, rich in complex carbohydrates, not from packaged products.
My guess is that it's far more than just the vital FIBER but also all the NUTRIENTS & ENZYMES naturally included and working together.]

- This article is about the same tribe in Tanzania, the Hadza. Yet, some details here are much more expansive than in the previous article. Both are important to read, each complements the other.
The discovery, in a study of hunter-gatherers in Africa, eventually may help scientists learn how modern diets have affected health.
by Carl Zimmer - The New York Times - August 24, 2017
Excerpt:
. . . By comparing microbiomes around the world, Dr. Sonnenburg said it might be possible to understand how gut microbes linked to industrialization are affecting people’s health. He has hypothesized, for instance, that they may be causing chronic inflammation.
In their new study, the researchers found that microbes in the guts of Americans make more enzymes known as mucins, compared with those in the Hadza. Mucins allow bacteria to harvest carbohydrates from the lining of our gut, rather than from plant fiber.
The result? “If you’re not feeding your gut microbiome with dietary fiber,” Dr. Sonnenburg said, “your gut microbiome is feeding on you.” -

How Many Viruses Can Live In Semen? More Than You Might Think
By Michaeleen Doucleff - NPR - September 23, 2017
Excerpts:
. . . Semen can be a hotbed for viruses, scientists report in the November issue of Emerging Infectious Diseases. At least 27 viruses can live in the fluid . . . .
. . . Doctors at the University of Oxford compiled a full list after analyzing more than 3,800 studies [link below]
Most of these viruses appear temporarily in semen after a person catches an infection. Others stick around for decades. . . .
The vagina's microbiome — or all the bacteria and viruses that inhabit it — can influence all sorts of health aspects, including the risk of miscarriage and HIV infection. . . . -
