Ácido fólico ou não ácido fólico?

Para todos ainda por cima, no fermento:
https://www.nhs.uk/news/pregnancy-and-child/case-folic-acid-be-added-flour-overwhelming-argues-review/

A falta de indicação do financiamento do estudo (e de declarações de interesse) é preocupante quando se propõem a alterar o que todos vamos comer?

Citando:
"What is the case for mandatory folic acid fortification?

As of October 2017, 81 countries had introduced mandatory fortification of flour. This includes the US, Canada and Australia, but so far no countries in the EU. The authors suggest this is because some expert committees undervalue the benefits of folic acid. The European Commission Scientific Committee on Food reportedly consider low folate as a "risk factor" rather than an "important cause" of neural tube defects.

There is also a widely held view that public health involves encouraging personal choice – such as through taking supplements – rather than making choices for everyone.

The authors say that fortification would not give full protection but would be "a population safety net" for women who haven't taken supplements before pregnancy. They give examples of legislation – such as smoking bans and car seatbelts – to reduce harm even if they impinge on personal freedom.

They mention how flour is already fortified with iron, calcium and other B vitamins like thiamine and niacin. They also say how folic acid would have wider benefits than just preventing neural tube defects, including reducing anaemia due to folate deficiency in older adults.(...)"

(...)

"The authors present a compelling case for folic acid fortification in flour to prevent neural tube defects.

The main drawback of this review is the lack of information on the research methods. It cannot therefore be considered to be a systematic review (...). As such this review has to be considered largely the interpretation and opinion of the authors."

"Sentido de vida" importante para qualidade do sono?

O NHS Choices analisa as notícias e diz que pode não ter a ver com o sentido de vida propriamente, ou seja a notícia é algo enganosa:
http://www.nhs.uk/news/2017/07July/Pages/Does-having-a-sense-of-purpose-in-life-help-you-sleep-better.aspx

Citando:
""Sense of purpose aids sleep, US scientists find," The Guardian reports on a new study that explored the relationship between having a sense of purpose in life and quality of sleep in older adults.

The study analysed data from 800 older adults with an average age of 80 in the US.

Researchers found that generally, having a greater sense of purpose in life was associated with better quality of sleep, as well as a decreased likelihood of sleep disorders such as sleep apnoea and restless leg syndrome. "

RHCP fazem bem à saúde?

Red Hot Chili Peppers (a comida, não a banda musical) fazem bem à saúde? É provável (devido a ingredientes antioxidantes) mas o estudo que motivou algumas notícias não prova grande coisa ainda):
http://www.nhs.uk/news/2017/01January/Pages/Hot-red-chilli-peppers-linked-to-longer-lifespan.aspx
Citando:
"A US study found that people who reported eating red hot chilli peppers had around a 13% reduced risk of premature death compared to those who avoided them.
The study looked at adults in the 1980s and 90s who reported eating any hot chillies over the past month – which could range from a single chilli to several chillies every day.
There were no significant links found when drilling down to specific cause of death rather than just overall mortality.
Ultimately this study proves very little."

Tratamentos possíveis: NHS Choices (e hiperplasia benigna da próstata)

O sítio NHS Choices apresenta de uma forma bastante sistemática e resumida as principais alternativas para tratamento de uma série problemas de saúde.

RESOURCE: NHS Choices Web Site (e o risco de cancro de quem bebe moderadamente)

O sítio NHS Choices (do SNS do RU) é um excelente recurso para aceder à fonte e interpretar algumas notícias sobre saúde que vão aparecendo:
