Dieta e depressão?
Sim:
https://www.sciencefocus.com/news/a-healthy-diet-could-reduce-the-symptoms-of-depression/
Citando:
"“Modifying diet to reduce processed food intake and increase consumption of fruit, vegetables, fish and olive oil improved depression symptoms in young adults,” say the study’s authors. “These findings add to a growing literature showing a modest change to diet is a useful adjunct therapy to reduce symptoms of depression.”"

Comida processada?
Nahhh:
https://www.bmj.com/content/365/bmj.l1451
Citando:
"Conclusions In this large observational prospective study, higher consumption of ultra-processed foods was associated with higher risks of cardiovascular, coronary heart, and cerebrovascular diseases. These results need to be confirmed in other populations and settings, and causality remains to be established. Various factors in processing, such as nutritional composition of the final product, additives, contact materials, and neoformed contaminants might play a role in these associations, and further studies are needed to understand better the relative contributions. Meanwhile, public health authorities in several countries have recently started to promote unprocessed or minimally processed foods and to recommend limiting the consumption of ultra-processed foods.
Study registration ClinicalTrials.gov NCT03335644."

O bacon e o cancro?
https://news.google.com/articles/CAIiEMwUm_PuNUDP_5rESc_0mkAqGQgEKhAIACoHCAow0Ij8CjCRwIgDMOSMzAU?hl=en-GB≷=GB&ceid=GB%3Aen.
Citando:
"It comes after a new study found that bacon and sausages fuel cancer twice as much as previously thought.
Just 25g of processed meat daily – equal to one rasher or 2/3 of a banger – raises the risk of bowel tumours by a fifth.
The World Health Organisation previously warned 50g of processed meat a day – two rashers or 1½ bangers – increased the risk of bowel cancer by 18 per cent.
But researchers from the University of Oxford now say a mere 25g each day is enough to raise the risk by 20 per cent."

Protector solar e oxybenzone
Mal menor ou maior?
https://www.dailymail.co.uk/health/article-6997513/Sunscreen-absorbed-blood-concentrations-419-TIMES-safe.html
Citando:
"Chemical oxybenzone reaches plasma concentrations of up to 209.6ng/mL
Food and Drug Administration in the US recommends no more than 0.5ng/mL
Oxybenzone may also disrupt our hormones, leading to embryonic toxicities "
(...)
"To put this to the test, the researchers analysed the active ingredients - avobenzone, oxybenzone, octocrylene and ecamsule - of four commercially-available sunscreens. Brand names were not given. "

Ai os glifosatos...
... desta vez não testados. Convenientemente:
https://www.theguardian.com/environment/2019/apr/08/pesticides-antibiotics-polluting-streams-europe-wildlife
Citando:
"The testing techniques used in the new research meant only a subset of pesticides could be detected. Two very common pesticides – glyphosate and chlorothalonil – were not included in the study, meaning the findings represent a minimum level of contamination. The research focused on streams, as these harbour a large proportion of aquatic wildlife."

Sobre a resistência aos antibióticos
https://www.theguardian.com/global/2019/mar/24/the-drugs-dont-work-what-happens-after-antibiotics
Citando:
"Antimicrobial resistance (AMR) – the process of bacteria (and yeasts and viruses) evolving defence mechanisms against the drugs we use to treat them – is progressing so quickly that the UN has called it a “global health emergency”. At least 2 million Americans contract drug-resistant infections every year. So-called “superbugs” spread rapidly, in part because some bacteria are able to borrow resistance genes from neighbouring species via a process called horizontal gene transfer. In 2013, researchers in China discovered E coli containing mcr-1, a gene resistant to colistin, a last-line antibiotic that, until recently, was considered too toxic for human use. Colistin-resistant infections have now been detected in at least 30 countries."
(...)
"Making a dent in antibiotic resistance will require such international efforts. Some 90% of forecast deaths from AMR will take place in Africa and Asia – the countries where antibiotic overuse, and resistant infections, are highest. When the AMR review was published in 2016, O’Neill was encouraged by the international response. But since then, Brexit and the Trump administration have knocked AMR off the news agenda. And despite enthusiastic rhetoric, pharmaceutical companies continue to tread water.
“I occasionally think that pharmaceutical company CEOs say to themselves, ‘We’ll just wait until it becomes a real crisis,’” says O’Neill."

Felicidade conjugal e os genes?
https://www.independent.co.uk/news/science/gene-marriage-success-relationship-dna-genetics-yale-university-a8802176.html
Citando:
"Some people have a gene linked with happy marriages, scientists find
'This study shows that how we feel in our close relationships is influenced by more than just our shared experiences with our partners'"
(...)
"People with this gene variant – known as the GG genotype – are already known to show greater empathy, sociability and emotional stability.
Given the kind of characteristics that might contribute to a happy and successful marriage, it is perhaps unsurprising that this was the stretch of DNA found frequently in content spouses."

Implantes mamários e cancro (EUA)?
https://www.foxnews.com/health/fda-alerts-doctors-of-rare-cancer-with-breast-implants
Citando:
" The earliest signs of the disease are usually lumps, swelling and pain around the breasts. Patients will often seek care from their primary physicians, gynecologists or other health practitioners, rather than a plastic surgeon, FDA noted.
"Having everyone informed about this is in the best interest of the patient," said FDA spokeswoman Stephanie Caccomo.
The cancer usually grows slowly and most patients are treated with surgery to remove the implant.
The FDA has been tracking reports of the cancer for years and officially confirmed its link to breast implants in 2017. The latest update comes as health experts around the world attempt to gauge the cancer's frequency and whether extra restrictions are warranted on certain types of breast implants. The FDA is holding a two-day meeting next month on the safety of breast implants."
Teoria da cerveja antes do vinho

https://news.sky.com/story/scientists-test-beer-before-wine-and-youll-be-fine-hangover-theory-11631169
Citando:
"University of Cambridge and German researchers plied 90 volunteers aged between 19 and 40 with alcoholic drinks to examine the "influence of the combination and order of beer and wine consumption on hangover intensity"."
(...)
": "A clear result in favour of one particular order could help to reduce hangovers and help many people have a better day after a night out - though we encourage people to drink responsibly.
"Unfortunately, we found that there was no way to avoid the inevitable hangover just by favouring one order over another.""

LISTA: Estratégias contra a adversidade?
Study identifies the most effective mental strategies that people use to get through aversive challenges - Big Think
Citando :
"The researchers started with a pilot study in which they presented hundreds of participants with challenging scenarios (such as completing a treadmill run) and asked them to list any strategies they'd typically use to push through to the end. The researchers collapsed the answers into 19 strategies most of which fell under one of two headings: situation modification strategies (e.g. drinking coffee; listening to music while working); and attentional deployment strategies (e.g. motivational self-talk or thinking the finish is near)."
A lista de algumas estratégias possíveis está aqui nesta imagem:

Citando:
"A “stealth disease” which causes iron to build up to toxic levels may be responsible for thousands of cancers and disabling joint problems written off as part of ageing, a British study has found.
Hereditary haemochromatosis is one of the most common genetic disorders among people of European descent but it had previously only been thought to harm around 1 per cent of people carrying the mutation."

Sobre a higiene dentária
A forma de escovar, a pasta com flúor 1350 ppm mais, cuspir em vez de bochechar no fim, menos de 4 sugar hits / dia:
https://www.dailymail.co.uk/health/article-6572643/Are-brushing-teeth-wrong-Dentists-reveal-four-tips-better-dental-health.html
Citando:
"How you brush makes a big difference. The mechanical act of brushing removes the very sticky dental plaque – a mixture of bacteria, their acids and sticky byproducts and food remnants.
It forms naturally on teeth immediately after you've eaten but doesn't get nasty and start to cause damage to the teeth until it reaches a certain stage of maturity. The exact amount of time this takes isn't known but is at least more than 12 hours.
Bacteria consume sugar and, as a byproduct, produce acids which dissolve mineral out of the teeth, leaving microscopic holes we can't see.
If the process isn't stopped and they aren't repaired, these can become big, visible cavities.
Taking two minutes to brush your teeth is a good target for removing plaque and you should brush at night and one other time daily. "
(...)
"Once you've brushed, don't rinse your mouth with water or mouthwash – you're washing away the fluoride! This can be a difficult habit to break, but can reduce tooth decay by up to 25 per cent."

Rabujice e mau feitio compensam?
http://www.bbc.com/future/story/20160809-why-it-pays-to-be-grumpy-and-bad-tempered?ocid=fbfut
Citando:
"The truth is, pondering the worst has some clear advantages. Cranks may be superior negotiators, more discerning decision-makersand cut their risk of having a heart attack. Cynics can expect more stable marriages, higher earnings and longer lives – though, of course, they’ll anticipate the opposite.
Good moods on the other hand come with substantial risks – sapping your drive, dimming attention to detail and making you simultaneously gullible and selfish. Positivity is also known to encourage binge drinking, overeating and unsafe sex."

Janeiro a seco?
Passar um mês sem beber? Sim, mas...
https://www.mirror.co.uk/lifestyle/health/dry-january-could-actually-bad-13799409
Citando:
"Although there are physical benefits to giving your body a break, Dr Wright warns that the approach is not the best psychologically for problem drinkers - and it won't improve your health if you just go back to your usual habits again.
He said: "Giving up alcohol for dry January as some sort of detox is like maxing out your credit cards all year and thinking you can solve your financial problems by living like a hermit for a month."

Bacon e Cancro?
Risco de cancro ainda não é levado a sério (desde estudo de 2015):
https://www.thetimes.co.uk/article/cancer-risk-from-bacon-must-be-curbed-urgently-say-campaigners-qv0wq0ppv
Citando:
"The cancer risk from processed meat such as bacon is still not being taken seriously enough, according to a statement by doctors and politicians.
The group, which includes Tom Watson, the deputy Labour leader, called for greater awareness of the “growing consensus” that nitrites in the meat produce carcinogens linked to bowel cancer. "

O Dr. Anti os Anti-vacinas?
https://news.sky.com/story/meet-the-doctor-curing-fake-news-italian-wages-twitter-war-against-anti-vaxxers-11584301
Citando:
"The anti-vaxx hoax, which claims that life-saving vaccines actually cause autism in children, has spread in Italy - and beyond - in recent years, causing a drastic increase in the number of parents who refuse to protect their kids from deadly diseases.
Waging a Twitter war against conspiracy theories, a 56-year-old doctor has become an unlikely celebrity in Italy, perhaps even a future political figure.
Roberto Burioni doesn't mince words, which is part of his appeal."

Longevidade e genes?
Nem tanto:
https://www.wired.com/story/the-key-to-a-long-life-has-little-to-do-with-good-genes/
Citando:
"It turns out that through every generation, people are much more likely to select mates with similar lifespans than random chance would predict. The phenomenon, called “assortative mating,” could be based on genetics, or sociocultural traits, or both. For example, you might choose a partner who also has curly hair, and if the curly-haired trait winds up being somehow associated with long lifespans, this would inflate estimates of lifespan heritability passed on to your kids. Same thing for non-genetic traits like wealth, education, and access to good health care. People tend to choose partners in their same income bracket with the same terminal degree, both of which are associated with living longer, healthier lives.
The first hint that something other than genetics or a shared family environment might be at work came when Ruby tried looking at in-law relatives."

Falta de exercício faz mal?
https://www.marketwatch.com/story/smoking-is-bad-but-sitting-around-doing-nothing-is-even-more-deadly-study-shows-2018-10-21
Citando:
"Smoking is bad for your health. You don’t need an oxygen tank by your bedside to tell you that. Diabetes and heart disease, obviously not great, either.
But what isn’t so obvious is that a sedentary lifestyle is actually worse than all three, according to a new study led by the Cleveland Clinic’s Dr. Wael Jaber.""
(...)
"These results were not drawn form a small group, either. Researchers retrospectively studied 122,007 patients who underwent exercise treadmill testing between 1991 and 2014.
“People who do not perform very well on a treadmill test,” Jaber said, “have almost double the risk of people with kidney failure on dialysis.” In fact, the risk associated with death is 500% higher for people with sedentary lifestyle than top exercise performers."
