I suppose the specifics are novel enough to warrant a paper, but on a layman’s level it has been known for decades that UV ages your skin rapidly.

I suppose the specifics are novel enough to warrant a paper, but on a layman’s level it has been known for decades that UV ages your skin rapidly.
- baxtr 10mo agoI don’t think it’s super straightforward. Another thing laymen know: Most younger people in southern Europe don’t look old.
- brabel 10mo agoI think that’s because locals have some level of adaptation to their region. In Australia, you can really see how the high levels of sunshine affect the Northern Europe descendants who live there today. Some 30 yo women look easily 40.
- blell 10mo agoI actually live in southern Europe and most of my friends who are >35 and have been out and about for most of their lives do indeed look much older than they are.
- 7bit 10mo ago"known" is the wrong word. Laymen know a lot of things, like ingesting lead, radium, mercury and arsenic. Up until a couple of years ago, people "knew" that one glass of wine a day was healthy, when infact every drop is poisonous to the body. In reverse, people thought (and too many still "know") that MSG and pasteurization is bad. Don't use the word know, when in fact you mean "assume".
- djtango 10mo agoIs MSG not bad for you in the way aspartame is not bad for you? I totally get that MSG is naturally present in dashi but the chemistry of dashi (a very messy and complex mix of substances) vs purified msg is going to be different, and the concentrations the japanese consume food containing dashi are very different to the way UPFs and chinese restaurants gratuitously smother your food in it. MSG is to many cuisines what butter is to western cuisine (ie moar is always bettah)
- sallveburrpi 10mo agoMSG is only bad for you because it makes things taste amazing so you are going to eat more than you actually should. Nothing wrong with butter btw. As with most food stuffs if not consumed in moderation it can become a problem.
- padjo 10mo agoThere’s no evidence linking MSG specifically with any chronic health issues and little reason to suspect there would be in healthy people at the quantities generally consumed. Funnily enough many people who are wary of MSG and try to avoid it would be better off looking at their sodium intake, which we know for sure has long term health risks.
- jtbayly 10mo agosalt is bad again?
- shlant 10mo agosalt was always advised to be limited, especially for those with high blood pressure. This hasn't changed, there are just vocal diet ideologues (mostly carnivore/keto) that are trying to post-hoc rationalize otherwise.
- amanaplanacanal 10mo agoFrom what I understand it's only really a problem for a specific set of high blood pressure folks. Something genetic I think. I'm on blood pressure medication, and haven't received any advice about sodium intake.
- loeg 10mo agoOnly ~50% of the population is hypertensive, and only about half of them are sodium sensitive.

- loeg 10mo agoA glass of wine a day is within epsilon of the most healthy possible option. You're making this out as if this is a big shift, but it isn't. There are just huge error bars on the measurements relative to the effect of the intervention.
- tannhaeuser 10mo agoWe can do better than "known for decades, on a layman's level" folklore and the answer actually isn't as straightforward ([1]). Recently there's even been discussion (by a Brit scientist I believe but I have no reference) on skin cancer vs more serious forms of cancer, and also about skin pigmentation playing a role here.

- anon373839 10mo agoThat link does not refute the claim that UV ages your skin, which it unquestionably does.
- adrianN 10mo agoYeah of course scientists can still learn more, but at some point the layman can’t really get any new information from the press release.
