"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?

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."

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”."

Ora aqui está a maneira correcta de definir um guia de saúde (health guide)

Alguns países como os US e o RU têm linhas orientadoras para a saúde (com resultados desastrosos). Talvez a forma como o casa

"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."

"One puff of any of the flavored e-liquids that we tested exposes the smoker to unacceptably dangerous levels of these aldehydes, most of which originates from thermal decomposition of the flavoring compounds," Khlystov noted in his statement.
"These results demonstrate the need for further, thorough investigations of the effects of flavoring additives on the formation of aldehydes and other toxic compounds in e-cigarette vapors.""
