"Smokers are most at risk, while other factors include drinking alcohol, having a diet low in fruit and veg, and infection with the Human Papilloma Virus (HPV), a group of viruses that affect the skin and the body’s moist membranes.
Mouth cancer – also known as oral cancer – includes cancer of the lips, tongue, mouth (gums and palate), tonsils and the middle part of the throat."

Citando:
"Instead they suggested those with lacking the vitamin should be advised about sunlight exposure and diet.
Sunlight is the main source of vitamin D, which can also be found in foods such as red meat, egg yolks, oily fish, liver and fortified foods like fat spreads and breakfast cereals.
Earlier this year Public Health England (PHE) advised everyone to take vitamin D supplements during autumn and winter.
A review found the equivalent of at least 10mcg each day is required but millions of people could be missing out. "

Machismo e problemas psicológicos?

http://m.scmp.com/news/article/2048580/playboy-type-men-have-higher-risk-psychological-problems-study-suggests
Citando:
"Psychologists looking at 10 years of data from nearly 20,000 men found that those who value having power over women and endorse playboy-type behaviour and other traditional notions of masculinity are more likely to suffer from psychological problems - and less likely to seek out help.
The new meta-analysis, which was published Monday in the Journal of Counseling Psychology, synthesised 78 studies on masculinity and mental health gathered between 2003 and 2013. The participants ranged in age from 12 to over 65, and the vast majority were men. A little more than half of the studies involved predominantly white men, though some focused on African Americans or Asian Americans. Most of the studies didn’t ask respondents’ sexual orientation, but among those that did, most of the participants were straight.
Researchers then identified 11 norms considered to be “traditionally masculine” - desire to win, need for emotional control, risk-taking, violence, dominance, sexual promiscuity or playboy behaviour, self-reliance, primacy of work, power over women, disdain for homosexuality and pursuit of status - and looked to see if they were associated with particular mental health outcomes."

Rejuvenescimento por tratamento do sangue - Calico | Google

Vão começar os ensaios clínicos (por 6 meses) de um tratamento altamente experimental depois de resultados em animais mostrarem resultados muito promissores (rejenuvestimento):
https://www.theguardian.com/science/2016/nov/22/scientists-to-reset-blood-proteins-in-attempt-to-slow-ageing-process-calico


Citando:
"People who take part in the trial will have their blood passed through a machine that resets abnormal levels of proteins seen in older blood. The scientists believe these high levels of certain proteins can hamper the growth and maintenance of healthy body tissues, and so contribute to their deterioration in old age.

Plans for the trial emerged as scientists announced the results of the animal study, which was part-funded by Calico, Google’s life extension company. The study showed that infusions of old blood reduced the growth of fresh liver and brain cells in young mice and impaired their performance in a strength test.

The same series of experiments found evidence that infusions of young blood could speed up muscle repair in older animals."

Bebidas energéticas, sim ou não?

Os benefícios (e os perigos) de correr em jejum

http://www.correrporprazer.com/2015/06/correr-em-jejum/


Citando:
"A ideia de quem procura os treinos cardiovasculares (corridas ou caminhadas) em jejum é aproveitar o período em que as reservas de açúcar estão baixas para estimular a queima de gordura mais cedo no treino. “A questão é que o nosso cérebro consome preferencialmente açúcar e, na ausência deste, vamos obrigar o nosso corpo a produzir corpos cetónicos. Prolongando este quadro podemos causar cetose, elevando a acidez do sangue”, defende o ‘personal trainer’ e professor de capoeira António Braz, lembrando que a acidose prolongada pode ter efeitos nefastos.
Henrique Jones, ex-médico da seleção portuguesa de futebol, considera que uma refeição ligeira uma hora antes do exercício “é fundamental para preencher as reservas energéticas que permitem alimentar os músculos”."

Mel de manuka, os chineses e a imunidade melhorada?

Ainda a ser estudado (originário da Nova Zelândia) mas uma loucura em termos de procura:
http://www.bbc.com/capital/story/20150828-the-golden-elixir-worth-more-than-gold?ocid=fbcptl
"(...) Molan discovered there was something special about manuka honey. It appears to have antibacterial properties, unlike other honeys in the world, and some studies suggested it could heal wounds and help boost the immune system. (Specifically, the antibacterial property found in other honeys comes from hydrogen peroxide, which is broken down quickly in the body, whereas the non-peroxide form found in manuka honey isn’t.)."

Citando:
"If you don't get fat from someplace, then you take energy from somewhere else, and it may be that children who are receiving reduced fat milk seek foods that are higher in caloric density, and maybe that's why they're a bit bigger," Maguire said in an interview."
(...)
"Childhood obesity in North America has tripled in the past 30 years. At the same time, children's consumption of whole cow's milk has halved over the same period.
Current guidelines from Health Canada and the American Academy of Pediatrics recommend two servings of low fat milk (one per cent or two per cent) milk for children over the age of two to reduce the risk of childhood obesity."

10 empresas dominam muito do que se come - Brexit

O infográfico do Huff. post é excelente para perceber o domínio de muitas empresas por muito do que se come e bebe hoje em dia. E que metem o RU em sentido (com as variações do valor da Libra devido ao Brexit):

"After Marmite and other products were pulled from Tesco in a post-Brexit vote pricing row, this sobering infographic is a reminder that a handful of companies own almost all of the food and drink brands in the world.
Unilever, the world’s second largest grocery manufacturer, reportedly halted deliveries its products including Marmite, Flora, Pot Noodle and PG Tips after Tesco reportedly refused to pay more for them after the pound fell in value."

Emulsionantes (comida processada) associados a cancro colorectal

http://www.sbs.com.au/news/article/2016/11/08/food-additives-may-cause-cancer-study


Citando:
"It's believed the emulsifiers alter the microbiota inside the intestines to create the ideal conditions for cancer growth.
The team of researchers fed mice with two very commonly used emulsifiers, polysorbate 80 and carboxymethylcellulose.
They observed that consuming the emulsifiers drastically changed the composition of the gut microbiota in a manner that made it more inflamed.
This change in the intestinal microbiota enhanced tumour development."

Efeitos do tempo na disposição estudados

E o número de horas de sol parece ser a variável mais preponderante (não se está chuva ou não):
http://m.jamaicaobserver.com/mobile/news/How-much-sun-time-are-you-getting-_79603


Citando:
"Your day might be filled with irritatingly hot temperatures, thick air pollution and maybe even pockets of rainclouds, but that won’t necessarily get you down. If you’re able to soak up enough sun, your level of emotional distress should remain stable. Take away sun time, though, and your distress can spike. This applies to the clinical population at large, not just those diagnosed with Seasonal Affective Disorder.
“That’s one of the surprising pieces of our research,” said Mark Beecher, clinical professor and licensed psychologist in BYU Counselling and Psychological Services. “On a rainy day, or a more polluted day, people assume that they’d have more distress. But we didn’t see that. We looked at solar irradiance, or the amount of sunlight that actually hits the ground. We tried to take into account cloudy days, rainy days, pollution . . . but they washed out. The one thing that was really significant was the amount of time between sunrise and sunset.”"

"'Before now, we had a large body of epidemiological evidence linking smoking with cancer, but now we can actually observe and quantify the molecular changes in the DNA,' he added.
Mike Stratton, who co-led the work at Britain's Wellcome Trust Sanger Institute, said it was a bit like digging in to the archaeology of each tumour.
'The genome of every cancer provides a kind of archaeological record, written in the DNA code itself, of the exposures that caused the mutations,' he said. "

Cozinhar acima dos 150 graus?

https://www.eurekalert.org/pub_releases/2016-11/uoe-ctm110216.php
Citando:
"Cooking food at temperatures above 150 degrees centigrade changes their chemical structure and can lead to the formation of toxic products known as neo-formed contaminants (NFCs).
These include trans-fatty acids - which are known to be harmful and are banned from food sold in many parts of the world - and other toxins called advanced glycation end-products.
Frying foods at a high heat is particularly problematic because the oils readily break down to form trans-fatty acids.
An international team - led by the University of Edinburgh - reviewed previous studies that have investigated the effects of NFCs on human and animal tissue. The studies explored the relationship between these products and heart disease risk.
Their findings revealed that cooking methods - including frying and roasting - which are common in South Asian countries created high levels of trans-fatty acids, especially if the oil is reused."

Privação do sono e apetite

Privação do sono e (maior) consumo de calorias abordados em novo estudo:

Citando:
"This study found that partial sleep deprivation resulted in a large net increased energy intake of 385 kcal per day.
If long-term sleep deprivation continues to result in an increased calorie intake of this magnitude, it may contribute to weight gain."
Dr Pot added: "Reduced sleep is one of the most common and potentially modifiable health risks in today's society in which chronic sleep loss is becoming more common.""

Ingredientes muito vendidos (Food Trends)

Os níveis de PSA e os exames e intervenções à próstata

Um relato em primeira-mão de uma história que começou com níveis de PSA elevados (testados por análises ao sangue):
http://m.huffpost.com/uk/entry/12751516


Citando:
"[I] had a PSA level of 16.  Now, PSA (prostate specific antigen, measured in nanograms per millilitre of blood) can give both false negatives and false positives.  Normal levels of PSA in the blood are between 0-2.5 ng/ml. Higher than normal levels, greater than 2.5, can be caused by cancer or by benign, non-cancerous conditions such as an enlarged prostate, prostate inflammation, infection, or trauma. But all elevated readings of PSA should be investigated."

Superbugs e ingrediente desinfectante

Citando:
"A laboratory study found the ingredient chlorhexidine, used in a wide range of antiseptic products, increased bacterial resistance to the antibiotic colistin.
Despite the headline to the contrary, researchers did not specifically test mouthwash or any other household products.
Colistin is what is known as an "antibiotic of last resort" and is used to treat Klebsiella pneumoniae bacterium that has evolved resistance to other more widely used antibiotics."
