The combination of low salt intake and {exercise/sauna/hot weather} is poor advice.
If your salt intake is low, and you start sweating due to hot weather, exercise or a new-found interest in saunas, you probably need to bump that up.
Google tells me that Americans consume on average 3.5g of salt, while the recommended intake is 2.3g. Quite some room there to decrease salt consumption.
I was diagnosed with UC in my mid-30's, am in my early 40's now. I used to deal with flare-ups about twice a year that always coincided with allergy season (May and October/November). I was living in Colorado at the time and was drinking lots of heavy craft beer quite regularly. Three years ago, I cut out about 98% of alcohol from my life, and when I drank, I only drank clear things - hard seltzers and gin. But only once or twice a month at the most. I hadn't had a flare-up in that entire time, until this last holiday weekend when I drank whiskey and was hit with horrible UC symptoms immediately. As someone in the throes of a flare-up right now, I have to say that research like this is promising. But yeah, for me alcohol, primarily darker alcohol like whisky and red wine, are an absolute trigger for me.
Have you ever looked into histamine intolerance?
I'm biased towards more practical books but here you go
- Designing Data-Intensive Applications by Kleppmann - not in your circle of interest necessarily but not in your circle of non-interest either.
- Introduction to the Design & Analysis of Algorithms by Levitin - not very popular but a great book. Interestingly, it groups algorithms around design techniques e.g. decrease-and-conquer, divide-and-conquer, greedy, DP.
- Algorithms by Sedgewick and Wayne - great algorithms book if your main programming language is Java, I keep coming back to it.

> Interestingly, .NET 6 implementation of the hash table keeps the items in the (rough) order of addition. To prevent potential correlation attempts, the hashed data is sorted before storing, effectively randomising the order of elements.
Can someone please explain how would correlation attacks be executed in this context?
I got OG Covid very early in 2020. I had something like a heart attack about six months later. It has not reoccurred. I suspect I had something kind of like a stroke a bit ago. The event was accompanied with very terrifying and specific neurological event. A loud noise that was only inside my head and unreal "sounding" that worked like a corkscrew from the right side of my head to the front while my vision dimmed. I legitimately thought I was about to die and was able to tell my partner so. It passed and I went to a doctor the following morning. More on that below. I've only noticed small motor function loss on my left side and some memory impairments. Since 2020 I have had what I call a "dinner plate in my chest". It goes away with some cardio exercise.
I can feel my vascular system radiating from the center of my chest up the sides of my neck and out through my shoulders. It's got a bit of a slow ache and upper body stiffness when it's flaring up. When it's bad, sometimes I wake up with numbness that radiates from my chest out to my finger tips on the top sides of my arms.
I have no problems taking deep breaths. The injury does not seem to be growing.
After the cardiac issue I had in 2020, my bloodwork showed signs that there was a possible event. My EKG was fine. This was days after. I have a constant dull to really shitty headache in the top front inside my head that has been persistent from the thing that seemed like a mini-stroke. I have never really had headaches without a serious hangover. I couldn't see my regular GP, still haven't been able to, but the doc I did see basically told me she thought it was vertigo and I needed to clean my ears. She checked my reflexes and some other things and said she could not recommend any further action without more events. I know what vertigo is. I've experienced it on accident and on purpose. I am not experiencing random vertigo. She did not seem to take anything I was saying seriously. She also told me she found it offensive that I was swearing while describing the experience and a gentleman would refrain from such language. I think she's a fucking moron, but she's functionally just as helpful as my curious, smart, and compassionate GP.
I'm 6' broad shouldered, and 210lbs. A bit chubby. I don't exercise a ton, but do some exercise, especially when the dinner plate flairs up. I don't smoke.
I've had a chest x-ray and it shows what looks like scarring in vascular structures radiating from my lungs. The forms kind of look on x-ray like the "ground glass nodules" that some people are experiencing. It's VERY hard to get a doctor that wants to do anything with me about this stuff. The fact that cardio makes things better and not worse is counter intuitive from traditional issues that look the same like Angina Pectoris. I've said since I recovered the first time (I've had it at least once more post vaccination but nothing was quite as near death as the first) that I felt cognitively and physically like I was 10 years older. I turn 40 next year. New research has been coming out showing that some people suffering from long COVID show aging of their CV systems of about 10 years.
It is going to take a long time to figure out what Long Covid is really doing to people. Some people that never showed symptoms get these things. Children are showing it too. The diagnostic criteria is really difficult and there is almost no treatment aside from some success with similar treatments used for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome[0]. I have found that most doctors don't want to touch it with a 200ft poll. The Red Cross says I should join an online support group[1]. A lot of the research is being done by scraping subreddits for people reporting symptoms because they vary so wildly and seem to have little correlation with the perceived severity of infection.
I suspect we may find a high correlation with exposure to heavy air born contamination. Like living in a very polluted city, exposure to lots of dust or chemicals, or living in a building with black mold for extended periods. The minor feeling or easy to ignore/temporary damage done by those experiences creating cellular damage that makes cells in CV systems pop like popcorn when COVID does its very unique number on vascular structures. The word Blood Foam was used once in a very early study on people who died from COVID. The images I remember from that study demonstrated that it is a pretty accurate term for what happens in the worst cases. I'm sure there are people with genetic properties that could just make them more susceptible as well.
I would also not be surprised if it ended up being correlated to heavy metals, dust/fiber, or fungal exposure specifically one or a pair of those things, even staggered exposure, being the biggest contributor. I expect that once its mechanisms are understood, the condition will not share a designation with other known pathologies. An interaction to an exposure and the damage certain coronaviruses do when given the right scaffold.

Holy shit, this is very similar to what my mom went through.
One day she heard a very loud bang that she described as sounding like it was coming from inside her head. Shortly after she started getting dizzy spells, specially when getting up in the morning and when lying down to sleep at night. Every once in a while her left arm would go numb and she would lose strength in it.
She went to many doctors and it was the same story, they thought it was vertigo. Thankfully she found a better one who requested a brain CT scan which showed that she actually had had a mild ischemic stroke on the right side of her brain.
Hope you are feeling better now, take care!

Just from my own anecdotal evidence, going clean vegan dropped my cholesterol levels from 6.1 to 5.1 in ~3 months. I’m pretty convinced there is a lot of truth to high saturated fat/animal products negatively impacting cholesterol levels. But that is my own personal experience.
I’d encourage anyone seeking insights to just try a vegan diet for a while and compare their bloodwork, and how they feel. Seems like little point looking for answers in the science because of the amount of noise.
Did you try going clean non-vegan before that?
When healthy people eat sugar, insulin is secreted and the blood sugar goes right back down. Overweight and obese people with time develop type-2 diabetes so they produce less insulin and due to excess fat around cells, their muscles don't respond as well to insulin anymore and can't take up glucose from the blood. That causes spikes in blood sugar and elevated levels throughout the day.
The answer to blood sugar control is being lean, and you can get lean by eating less fat. The clue is in the name, really.
