Wednesday Open Thread: A New Connection between the Gut and Brain
It's Day 23 of the Year 2019 CE, meaning that it's January 23, 2019
The full headline, in the article to be cited below is:
A New Connection between the Gut and Brain
A surprising way that diet leads risks of stroke and cognitive impairment
Look at that mix and match, gut-brain connection, and diet. Gut-brain pathways have been on the radar for quite some time and consist, until very recently of endocrine (hormones and such), neurological (Vagas Nerve), and immune (cytokines). So what's all this now? Would you believe new news about old news? How about NaCl - Sodium Chloride, aka salt, as in table, sea, and all that. So, this is coming from the following article: https://www.scientificamerican.com/article/a-new-connection-between-the-...
Ok, too much salt is bad. It causes high blood pressure, putting you at increased risk for heart attacks, strokes and the like. However, somewhat recent studies have shown high salt intake to be associated with strokes even in the absence of high blood pressure. As a result there have been some searching for a heretofore unknown link between salt and brain health issues. There is also a lot of work being done on the gut-brain axis and a growing knowledge that disruptions thereof can contribute to a wide range of diseases, including Parkinsons. The growth of research in this area included a couple of studies showing that high salt consumption led to serious immune changes in the gut which in turn made the brain increasingly susceptible to auto immune attacks.
Now, new research shows another connection: immune signals sent from the gut can compromise the brain’s blood vessels, leading to deteriorated brain heath and cognitive impairment. Surprisingly, the research unveils a previously undescribed gut–brain connection mediated by the immune system and indicates that excessive salt might negatively impact brain health in humans through impairing the brain’s blood vessels regardless of its effect on blood pressure.
The phrase "new research" is linked to this abstract Dietary salt promotes neurovascular and cognitive dysfunction through a gut-initiated TH17 response, here: https://www.nature.com/articles/s41593-017-0059-z#Sec12 OK, excessive salt intake can be trashing your brain even without elevating your blood pressure. Good to know if you're a hard core salt addict like myself. Isn't it nice to know that all of our processed, prepared and restaurant food is massively over salted?
Two more non-adjacent paragraphs from the article:
The researchers used mice, and found that immune responses in the small intestines set off a cascade of chemical responses reaching the brain’s blood vessels, reducing blood flow to the cortex and hippocampus, two brain regions crucial for learning and memory. This, in turn, brought a decline in tests of cognitive performance. The impairment in learning and memory was clear even in the absence of high blood pressure; they observed that the gut is reacting to the salt overload and directing immune signals that lay the basis for deterioration throughout the brain’s vital vascular complex and compromise cognitive function. While this study has only been carried out on research animals so far, the scientists believe it's likely that much of the same applies to people.

The implications of this newly identified gut–brain connection extend to several auto immune disorders, including multiple sclerosis, rheumatoid arthritis, psoriasis, and inflammatory bowel disease, that have been shown to activate the same immune signaling pathway implicated in this study. These auto immune disorders have a high stroke risk and are linked to poorly functioning blood vessels in the nervous system. This research is also a demonstration that what we eat affects how we think, and that seemingly isolated parts of the body can play vital roles in brain health. These results motivate research on how everyday stressors to our digestive systems and blood vessels might change the brain and, consequently, how we see, and experience, the world.
I can attest to the bit about outlook, for I've always had a somewhat salty outlook on life. Nonetheless, let us not forget that salt is necessary for survival, it is simply a question of balance. According to the article, almost everybody around the globe consumes too much salt, about twice what the WHO recommend. Perhaps that's because, relatively speaking, almost everybody around the globe is part of the working class and thus:
And remember, high blood pressure needn't be present for these effects to occur:

Heh, just thinking about how many times...
I've eaten out recently. Usually is about once or twice a month. I just can't AFFORD it. Grocery Outlet is my friend these days.
Now I'm just going to spitball on the salt theory a bit. Salt Dehydrates. Dehydrated people ALSO don't think well. Add in the vast amount of processed Corn syrup the vast majority of American's eat, and it's no wonder we can't think straight.
Serving in Iraq may have been a boon in one area. I'm very aware when I'm dehydrated these days. If I am not properly hydrated, I get Gout attacks, so I have to stay on top of it. Also I notice I don't tend to think clearly, make poor choices, etc... when I don't drink enough water.
So, yeah, I am of the theory that we can no longer think about our health solely symptomatically. While the Medical field seems to be doubling down, trying to find the ONE cause of it, I think American poor health and decisions are linked. Sick people make decisions based off what they think will make them feel better. Painkillers of all kinds are usually the first decision. Unfortunately, those also kill your thinking about other solutions. Yes, OVERWHELMING pain needs a painkiller, but pain is a sign something is wrong. America has just duct taped over the warning light.

I do not pretend I know what I do not know.
"Medical field seems to be doubling down" Great!
I got off the pHarma wheel a few years ago, they're worse then heroin pushers if you ask me. Legal! Like bribery in politics is now. Perfectly normal. The mental health system already collapsed, nobody noticed.
NOBODY lol

Legalization of marijuana off to sluggish start in Sonoma County
So from zero to jack boot in two years. Thanks BCC.
When Big Al says "somebody from California" will complain about citizen ballot initiatives it's probably me. wah Proposition 64 was not a good law, so our legislature made it worse, because of course. D-BIGly investors came and bought up all the little licenses, sacramento gave middle finger to timber families up north. Same as it ever was.
waiting for cascadia
blah blah blah
peace
I'm going to therapy these days...
Took the kids to PCC last night to look into welding classes. Looks interesting, but we'll have to do it during the summer because we have to get permission from her school in order to learn.
I will repeat that.
We need permission from the government, to teach my kids how to weld. This right here is WHY I want to learn outside the university if possible. Because while we're sitting around fucking with paperwork, we could have had ten lessons by the time it's done.

Teachers to return to classrooms Wednesday
ok
woo hoo congratulations... ?

Thank you for the Mazatlan ear worm, will be driving the cow shortly. lol Cool flag, check out the middle, needs some funny quotes to go with:
is that deer blowing smoke or what. laugh bubble? there are no words

Happy Hump Day!
peace
Edit: Brocket Deer
thanks
la teacher strike ending a good thing...
? I hope so but have little faith in the system. cuts have been happening every year since the late 70s when my kids were in school and they are still happening. not much to cut. meh!
green veggies best vitamin bang for buck. Eggs best cheapest source of protein. The body needs a lot of different oils/fats to survive but I don't remember which ones. new info out on that. butter creates more global warming than red meat. bummer. (see blog tomorrow) reading lots of foody stuff. ag. https://www.eatforhealth.gov.au/food-essentials/fat-salt-sugars-and-alco... on fats salt and sugars. drink no alcohol says new studies. none. all bad. hmmmm... beans and rice. thanks for the ot. have a good one el et al...

One year since my dietary kibitz
tempus fugit. Was able to get my weight up to 130 and keep it on, mostly. Normal BMI, not low. Thanks for all the ideas from everyone. I rarely eat meat, but adding milk and cheese back to my diet was a good thing. Still mostly grains and beans, some veggies, and not enough fruit, that's my "diet". Sometimes I run out at the end of the month, so I pretend like I'm fasting. Works fine. I never crave fruit, but I always always crave salt. huh
Gut trouble, it comes and goes like the depression. sneaky I read the SA article, downloaded the PDF. Huh and huh, I have more to think about now, so thanks.
Coinky-dentally "salt of the earth" was the subject of the email I sent to my farming friend, who gifted me a four pound jug of salt from costco last year, or maybe the year before. It's about half gone now. hmm But then I looked it up, and thought it's not a very nice thing to call someone "the salt of the earth" oops Well I know we will have a good laugh about it next time I see her anyway, I know nothing about the bible words, and she preaches them out every Sunday.
doh
Who thinks they should
describe themselves as the salt of the earth? No one I know that actually works for a living. According to The American Heritage Book Of Idioms that phrase originated in the Bible where Jesus supposedly said that those who were persecuted for being loyal to him were the salt of the earth. The only people I know who consider themselves the salt of the earth are either deluded by various ideologies or not in the 99%. Of course they attribute that quality (ie the status of being as important as salt) to themselves, as opposed to someone else saying it about them. Hence, they seem to me to be a pathologically arrogant crowd.
That being said, one of my all-time-favorite snacks is very salty, buttery, popcorn.
Good morning all and thanks for the OT e.l.
Good morning, el ~~
I need to tune in better to the dialogue between my gut and brain. I didn't realize a conversation was taking place all these years. Why haven't I been told this before? (hands on hips, taps foot)
We don't eat out much. We live in a rural area with few eat-out choices, which is better all around for us. I'm better able to control my food intake, which I prefer. We, obviously, have to eat out when we travel, although I do bring along a lot of our own food and try to stay in places with kitchenettes. It is also why we prefer traveling in an RV - I can control our food prep, etc. I'm a salt-a-holic. So is my granddaughter. We have to watch our intake...
Have a beautiful, salt-controlled (and tune into that convo taking place), day, folks!
