Make sure those mushrooms are prepared well though because as I understand it, the human digestive system has a hard time breaking down chitin cell walls, so without proper preparation, the mushrooms may pass through mostly undigested.
The point about letting the mushrooms soak up sunlight to boost their vitamin D content is totally true and absolutely fascinating though!
> When commonly consumed mushroom species are exposed to a source of ultraviolet (UV) radiation, such as sunlight or a UV lamp, they can generate nutritionally relevant amounts of vitamin D. The most common form of vitamin D in mushrooms is D2, with lesser amounts of vitamins D3 and D4, while vitamin D3 is the most common form in animal foods. Although the levels of vitamin D2 in UV-exposed mushrooms may decrease with storage and cooking, if they are consumed before the ‘best-before’ date, vitamin D2 level is likely to remain above 10 μg/100 g fresh weight, which is higher than the level in most vitamin D-containing foods and similar to the daily requirement of vitamin D recommended internationally.
I've recently run into and explored research explaining that natural sunlight stimulates energy production in mitochondria, resulting in an energizing and healing effect completely separate from vitamin D production.
I feel bad for posting this without references so here's one reference I could find right now:
> This study shows that longer wavelengths in sunlight are transmitted through the body. When these are presented via NIR LEDs in a laboratory-controlled environment at much lower energies, they again have the ability to be transmitted through the body and also are associated with improved visual function independent of ocular exposure. Hence, body penetration by longer wavelengths impacts systemically. Longer wavelengths improve mitochondrial membrane potential and ATP production and improve function in a species conserved pattern that can impact on mobility, visual function and cognition, particularly in ageing. In short lived animals they can extend average life span.
> Taken together, these data provide evidence of the importance of the full spectrum of sunlight for human health. They also highlight the potential dangers of the restricted spectra found in white LED lighting in the modern built environment that lacks longer wavelengths and whose output is generally restricted to around 400–650 nm. The absence of longer wavelengths from LED light sources may have implications for public health that should be addressed.
Funny that I should run into this now... Just this past weekend I tried the Home Assistant backup/restore mechanism for the first time, and it failed miserably for me :-(.
First it took over an hour to create the backup, then I got a 4.42 GiB tar file, that of course failed to upload to the new Home Assistant install.
I investigated and found that the tarball was just a compressed copy of the complete installation directory of my Home Assistant setup, and that included multi gigabyte `.cache/pip` and `.cache/uv` directories :-s (my old Home Assistant install operates from a Python virtual environment that I created, and Home Assistant keeps nagging me that this installation method is deprecated, so I decided to migrate to HAOS in a VM).
When I deleted those directories the tarball was less than 200 MiB but the new HAOS VM still would not accept the upload. All I got was "500 Internal Server Error - Server got itself in trouble". And of course because HAOS is an "appliance" its kind of a black box so I couldn't find out how to get access to error logs with details :-(.
In the end I decided that the path of least resistance was to simply start from scratch based on the HAOS virtual machine and take some days/weeks to build up the new Home Assistant setup before it's mature enough to take over from the old Home Assistant setup (which is running on hardware that is close to failure).
If you are at all comfortable with Linux system administration, manually setting up one or a handful of KVM/qemu powered virtual machines is not actually that hard at all (in my experience). If you like a GUI to guide your initial steps, "virt-manager" is pretty okay. I've been running 3-5 virtual machines for several years now based on a pretty vanilla Ubuntu Linux install (Debian would work just fine as well).
Now I do like a challenge every now and then, so I'm currently setting up Proxmox to gain live migrations and high availability for virtual machines, because I've become quite dependent on all of these services in virtual machines actually running successfully :-) even in the face of eventual hardware failure (like what happened to me in the past months).
