YSK - for all the things that can make your life easier!

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with YSK.

All posts must begin with YSK. If you're a Mastodon user, then include YSK after @youshouldknow. This is a community to share tips and tricks that will help you improve your life.



Rule 2- Your post body text must include the reason "Why" YSK:

**In your post's text body, you must include the reason "Why" YSK: It’s helpful for readability, and informs readers about the importance of the content. **



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-YSK posts.

Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you harass or discriminate against any individual member, you will be removed.

If you are a member, sympathizer or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- The majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.



Rule 11- Posts must actually be true: Disiniformation, trolling, and being misleading will not be tolerated. Repeated or egregious attempts will earn you a ban. This also applies to filing reports: If you continually file false reports YOU WILL BE BANNED! We can see who reports what, and shenanigans will not be tolerated. We are not here to ban people who said something you don't like.

If you file a report, include what specific rule is being violated and how.

According to Harvard research, eating oranges stimulates growth of Faecalibacterium prausnitzia.

This bacteria lives inside the human gut and generates serotonin and dopamine β€” 2 powerful molecules that elevate your mood.

Harvard is one of the top 5 research universities in the world. Gary Ruvkun won the 2024 Nobel Prize in Medicine. Where does he work ? Harvard.

YSK is such a pale imitation of TIL. Please disagree, I've been baiting all fucking night and you all are way too chill. There is zero lively conversations on Lemmy. "but we don't have bots" the fuck you don't, in the mornings I see bots constantly importing reddit threads. I feel like I'm on fucking 1998 usenet. DEBATE ME!

[–] RightHandOfIkaros@lemmy.world 6 points 7 hours ago (1 children)

I don't wanna be that guy, but I have to be fair and ask:

Why should I know this?

[–] Sludge@sh.itjust.works 7 points 7 hours ago (1 children)

Because if you're sad now, but you want to be happy - you should probably eat an orange. It's a nice thing to know

Yeah I know, but its not in the body of the post per Rule 2. Plenty of really bad YSKs that didnt belong here had the same thing and I called some of them out too. So in order to be fair I have to ask it here too, thats all.

YSAK: If you don't feel sad, eat an orange

Oranges are yummy and keep you from getting scurvy

This post has been paid for by The Orange Gang

I have never personally known anyone with scurvy... But yeah, they are tasty.

[–] JohnnyEnzyme@piefed.social 13 points 14 hours ago (2 children)

Oranges and other citrus fruit are also significantly acidic, which is hard on teef. So try not to go overboard, or at least rinse your mouth with water afterwards if you eat citrus regularly.

By the same token, do not rinse your mouth with water after brushing your teeth. This gives more of the toothpaste's fluoride a chance to adhere, from my understanding.

[–] Eric@lemmy.blahaj.zone 1 points 4 hours ago

It is an exposure thing, so you're better off eating it in one sitting rather than snacking on acidic things throughout the day.

[–] Steve@startrek.website 6 points 11 hours ago (1 children)

Can I eat the juicy orang right after brushing my teefers?

[–] JohnnyEnzyme@piefed.social 4 points 10 hours ago

Maybe save a step, and simply brush your teef with the orange!

[–] eleijeep@piefed.social 13 points 13 hours ago (1 children)

Oh yeah emotions are just nutritional signals and gut-bacteria signals, I guess we're all just making up reasons to be ABNORMAL AND DIFFICULT.

THANKS HARVARD NERDS

Ever thought about eating an orange?

[–] digdilem@lemmy.ml 6 points 12 hours ago

What if you're sad about the price of oranges?

Advice from the little book of calm.

[–] yermaw@sh.itjust.works 21 points 16 hours ago (1 children)

If you cant find an orange, pretend you're eating one, and then laugh.

The waves are scary if you don't read it correctly though.

[–] scytale@piefed.zip 11 points 17 hours ago (3 children)

Does it work with (non-artifical) orange juice as well?

[–] Buffalox@lemmy.world 6 points 14 hours ago (1 children)

If it's artificial it isn't orange juice.

[–] RedMari@reddthat.com 1 points 11 hours ago (2 children)

Artificial juice can definitely be orange (from dyes) πŸ€“

[–] Buffalox@lemmy.world 1 points 2 hours ago* (last edited 2 hours ago)

True, but here (Denmark) it is literally illegal to sell anything but pure fruit juice as juice, if it is made from concentrate it has to be labelled clearly, and it is only allowed to ad the amount of water that was removed.

If it has added sugar it is called Nektar.

If it has artificial flavors it is called Saft. Saft can also have added sugar. Saft also means Juice, English does not AFAIK have the words to distinguish between pure juice and flavored and sweetened juice.

IDK the rules in other EU countries, but my guess is that they are similar, but localized depending on language.

At least for me, all citrus fruits including their juices have an effect that they make me somewhat happier and help somewhat against depression. In the winter, I usually eat several mandarins a day.

[–] jared@mander.xyz 3 points 17 hours ago

If the bacteria can get what they need from it, i imagine the less processed it is the better.

[–] Kolanaki@pawb.social 10 points 17 hours ago* (last edited 17 hours ago) (1 children)

I always just thought it was the sugar in the OJ making me feel better. πŸ€·β€β™‚οΈ

[–] Broadfern@lemmy.world 7 points 16 hours ago

Orange juice also has some magnesium in it which can slightly help with pain and such.

I drink it when I get a migraine and always thought it was the sugar too till I found that out.

[–] Grandwolf319@sh.itjust.works 7 points 17 hours ago (1 children)

Does this work with dried oranges?

I drink a tea that has orange in it so it would be awesome if it applies

[–] Ephera@lemmy.ml 3 points 9 hours ago

I mean, this research wouldn't be able to tell what about oranges makes these bacteria thrive, so would need a separate study for dried oranges or similar variations.

Having said that, your tea likely has so little actual orange in it, that it's very likely negligible either way.
There's probably just a tiny bit of orange in each tea bag to begin with, and it might even just be orange peel. And then it's just traces of that which go into your tea water, too.

Of course, drinking tea in general can probably also help with depression in some way. At the very least, it hydrates you and presumably improves blood circulation, which can help get you out of a rut.

[–] HubertManne@piefed.social 2 points 16 hours ago (3 children)

do people hust have oranges lying around. We get them sometimes when they are in season enough to be cheap and nice.

[–] Watermark710@piefed.social 1 points 7 hours ago (1 children)

I eat at least 2 blood oranges a day, sometimes 5 or even 6. They taste so damn good, and they're relatively cheap ($1.49/lb). I literally always have at least 4 pounds on hand, but I just restocked, so I've got 12 pounds at the moment. Sometimes, in the summer, I buy extra so I can juice them. Then I mix the juice with pomegranate juice, and pour the mix over ice in a kala namak rimmed glass. Vodka optional.

[–] turdburglar@piefed.social 2 points 5 hours ago

well alright then.

[–] Drusas@fedia.io 2 points 11 hours ago

I usually do because they're tasty, they stay good for a long time, and they're available cheaply year round in the US.

[–] Mesa@programming.dev 2 points 16 hours ago

I love me some good navel oranges. So, on a good day, yes.
