How Fermented Foods May Alter Your Microbiome and Improve Your Health
https://www.nytimes.com/2021/08/13/well/eat/yogurt-kimchi-kombucha-microbiome.html

Foods like yogurt, kimchi, sauerkraut and kombucha increased the diversity of gut microbes and led to lower levels of inflammation.

I wonder if eating the lactobacillus in yogurt provides some of this protective effect to the sinuses — from bits of chewed food that get from the mouth to the nose

Holcomb et al. (1991) reported that both L. acidophilus and
Bifidobacterium were able to survive and grow in soft-serve frozen yogurt after freezing [Holcomb, J.E., Frank, J.F. and McGregor, J.U. (1991), Viability of Lactobacillus acidophilus and Bifidobacterium bifidum in soft-serve frozen yogurt. Cult. Dairy Prod. J. 26, 4-5.]

pre-frozen yogurt can contain active cultures — just have to check the label.

“For people, a drug that’s safe for use during pregnancy may help. A probiotic, many of which have anti-inflammatory properties, may also be of benefit. Not coincidentally, asthma researchers are arriving at similar conclusions; prevention of the lung disease will begin with the pregnant woman. Dr. Parker has more radical ideas: pre-emptive restoration of “domesticated” parasites in everybody — worms developed solely for the purpose of correcting the wayward, postmodern immune system.

Practically speaking, this seems beyond improbable. And yet, a trial is under way at the Montefiore Medical Center and the Albert Einstein College of Medicine testing a medicalized parasite called Trichuris suis in autistic adults.

First used medically to treat inflammatory bowel disease, the whipworm, which is native to pigs, has anecdotally shown benefit in autistic children.

And really, if you spend enough time wading through the science, Dr. Parker’s idea — an ecosystem restoration project, essentially — not only fails to seem outrageous, but also seems inevitable.”

As microbiome signatures mature, law enforcement or intelligence agents could theoretically track people by looking for traces of them left in the microbes they shed. Mark Gerstein, who studies biomedical informatics at Yale University and was not involved in the new study, suggested, for instance, that one could imagine tracking a terrorist’s movements through caves using their microbiome signature.

Huttenhower and his colleagues were identifying individuals out of pools of just hundreds of project participants, however. It is currently unclear how well the algorithm will perform when applied to the general population, though the researchers estimate that their code could likely pick someone out from a group of 500 to 1,000. “I would expect that number to get bigger in the future as we get more data and better data and better coding strategies,” Huttenhower said.

But the work raises privacy concerns similar to those faced by scientists gather human genomic data. Microbiome researchers are already wary of the human genomic DNA that gets caught up in microbiome sequences, but it increasingly appears that the microbiome sequences themselves are quite personal.

In the genomics field, researchers have increasingly limited access to databases containing human genomic sequencing data. Researchers must apply to use these data. “People might increasingly want to put the microbiome data under the same type of protection that they put normal genomic variants under,” said Gerstein. “Your microbiome is associated with various disease risks and proclivities for X and Y. I don’t think it’s a completely neutral identification. It potentially says things about you.”
