The abstract is a little concerning, but the good news is that this suggests that the gut biome does have influence on the brain, and perhaps that influence can be reversed or utilized with engineered biomes and/or bacteria.

Perhaps the path to transhumanism will start at the gut.

Sometime in the last 20 years we simply stopped talking about fiber, and both kinds play a big role in gut biota. It's like we've simply given up on it. Probably most of us aren't getting anywhere near as much pectin in our diets as we used to, let alone vegetables.

The funny thing is that the anti-sugar keto people are also even more anti-fiber. They'll tell you that you just need to eat steak and fats and nothing else and fiber is part of the "healthy whole grains" lie. I'm not sure if any of them are into gut microbiome science yet.

I don't think that this is true. Keto people I've met are very into the idea of 'net carbs': carbs minus fiber.

Wow, some astonishing Reddit posts about this if you search /r/carnivore for "poop".

I really think that nature's domain name causes people to misjudge articles like this. Nature is a very very reputable journal, but the domain (nature.com) hosts all of their (albeit still very nice) derivative journals.

To the casual observer who doesn't click the link (and just reads the headline on HN), it appears that many articles are Nature articles, when in-fact, they are articles from other journals.

This is published in Translational Psychiatry, which is still a reputable journal by all measures, but it appears to be in Nature by domain alone. The difference between Nature and its sub-journals are quite significant, since Nature is reserved for the "cream of the crop." So, to the casual observer, it may appear as a larger breakthrough than it may be.

I only point this out because I've definitely had the "ooh, a new article in Nature on HN?" reaction, only to be left wanting more because the article isn't a Nature article.

Brocoli, cauliflower, lettuce... all highly recommended by every book. You discover the need for fibers very fast when starting keto.

I asked about fiber once in /r/ketoscience and everyone yelled at me for suggesting they eat a vegetable.

Good callout. I absolutely had this reaction to it.

I keep getting this ad on YouTube by some alpha hipster complaining about all the toxic poop in your gut, like he thinks that your GI tract would be better if it were empty all the time. That’s not how digestion works, sport. You don’t have thirty odd feet of intestines because evolution was too stupid to make a shorter trip from your mouth to your butt. Your first clue should be that it’s folded up on itself.

I believe it, inflammatory responses causes so many things we are only now starting to see in the past 15 years, lots of autoimmune diseases that had no cause or correlation to anything seem to be a direct byproduct of a modern Western diet--sugar based. It's crazy but I used to mock the idea of fasting from a biological perspective (an education emphasis on glucose and misc metabolic pathways to create ATP etc...) b…

Some time in the last 100+ years we've started talking about fiber, and the benefits are still dubious.
