A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted, clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts: 1
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- If you feel strongly that you want politics back, please volunteer as a mod.
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report the message goes away and you never worry about it.

Are you sure there was only one tuna in the can? I don't eat cans often but have you ever gotten a different batch of tuna? Like different sizes of chunks, different curl? I wouldn't be surprised if into one can a sorted batch of similar patches from different tunas was packed. "To ensure the quality of experience"
Possibly, but it's always been quite hard to tell. Whenever I get cans it's always in tiny flakes so I guess that could be from multiple tunas if one can needed a top-up etc.
If you get the more expensive brands or varieties it's more likely to be solid pieces vs a slurry.
If you buy more expensive tuna, you'll get cuts that are clearly from one fish. Albacore, for instance, I've never seen come in that shredded form.
Also, if you're interested in sustainability, look for line-caught tuna. It's not the only sustainable fishing practice, but it's an eat one to remember. In the US, there's an MSC certification on the can that's a reasonably indicator that the company practices sustainable fishing.
If you're getting cans full of flakes, it's probably not all from the same fish, or even the same kind of tuna.
Hmm looking at the can I got from Aldi in the UK, it says 'responsibly sourced' (whatever that means) but doesn't have an MSC certification. I'll see if I can find cans that do in future!
I think the MSC certification may only apply in the US. The UK probably has different certifications.
Ah no, I've seen the logo before and there's a report about it here: https://www.msc.org/docs/default-source/uk-files/msc-uk-tuna-shopper-report-2023.pdf?sfvrsn=5309aa2f_7
It feels like you're imagining a system where people are loading cans from sides of tuna, when in reality it's probably much closer to the cans being filled by a machine loaded with a hopper just packed full of large batch tun chunks.
This video seems to suggest that quite a lot of the process is manual: https://www.youtube.com/watch?v=mt3SbqYAbf4
People deboning, sorting it and so on. It's not entirely clear but yeah they seem to load hunks of meat in which I guess a machine then places into cans.
Yeah they don't show the actually canning step it seems, but it looked like they were sorting them into different batches and from my limited experience on packing lines things get big batched.
Why is tuna like that? As opposed to say canned salmon which is immediately identifiable
No idea. But isn't it that salmon meat more sticks together when tuna meat more often breaks apart?
Did some googling.
Tuna is massive and lean by default and has more denser muscle and less fat. Fat holds it together and stops it falling apart. The lean muscle makes it taste dry. Tuna has to be chunked to get anything into a can.
Salmon is way smaller (typically can sized), very fatty and has fast-twitch muscle, all of which lead to a juicier more cohesive fillet.
To think, one shower is all it takes to explore the flesh of fish :D
Shower?
According to OP, that question was a showerthought
