Rules:

Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Ultra-processed food increases risk of early death, international study finds (www.theguardian.com)

Consuming large amounts of ultra-processed food (UPF) increases the risk of an early death, according to a international study that has reignited calls for a crackdown on UPF.

Each 10% extra intake of UPF, such as bread, cakes and ready meals, increases someone’s risk of dying before they reach 75 by 3%, according to research in countries including the US and England.

UPF is so damaging to health that it is implicated in as many as one in seven of all premature deaths that occur in some countries, according to a paper in the American Journal of Preventive Medicine.

They are associated with 124,107 early deaths in the US a year and 17,781 deaths every year in England, the review of dietary and mortality data from eight countries found.

Scientists only use terms like ultra processed food after defining them in their scientific papers. The problem here is that the media find it difficult to write a short article for the general audience if they have to define things scientifically.

What specifically is bad about UPF foods is still being researched. A few leading ideas are:

Very little fibre
Starches are all immediately accessible to digestion and so blood glucose spikes much more than for the non-UPF equivalent
UPF foods are soft and dry (so weigh less) making it very easy to eat a lot very fast, so you eat too many calories.
Relatively high in salt and sugar
Use of emulsifiers. These may change your gut microbiota and also make your gut more leaky causing inflammation
Use of preservatives and artificial colours
Frequently have a lot of oil

Low fibre, emulsifiers and preservatives, while lacking variety of phytochemicals found in fresh food is known to change your gut health. People on UPF diets tend to eat more and have higher blood glucose spikes leading to heart disease and diabetes.

Altogether this is a recipe for a shorter, less healthy life

Those are shit definitions that come from pop-science not real science. They're so broad as to be functionally useless.

[–] exasperation@lemm.ee 1 points 3 hours ago (1 children)

The NOVA classification system is "real" science, but in my opinion the arbitrary and vague definitions make it so that it's not very good or very robust science.

[–] turmacar@lemmy.world 1 points 2 hours ago

"Very little fiber", "Frequently have a lot of oil", and "Relatively high in salt and sugar" aren't a classification, they're vibes.

"Use of Emulsifiers" is worthless. Eggs, garlic, and butter are emulsifiers.

NOVA is not about finding stuff out, it's about creating a science-y sounding framework to replace the food pyramid.

Use of emulsifiers.
Frequently have a lot of oil

Oh no, not my mayo!

...is aioli ok or do saponins count as emulsifier, here?
