"Previous studies have suggested that young people who spend more than two hours a day on social networking sites are more likely to report psychological distress. “Seeing friends constantly on holiday or enjoying nights out can make young people feel like they are missing out while others enjoy life,” the #StatusOfMind report states. “These feelings can promote a ‘compare and despair’ attitude.”"

Dos benefícios do exercício físico

https://www.publico.pt/2017/06/15/ciencia/noticia/exercicio-fisico-cansa-va-la-basta-uma-sessao-para-acordar-o-cerebro-1775665

Citando:
"O artigo conclui que os efeitos mais consistentes de uma só sessão de exercício físico são uma melhoria da função executiva (a capacidade de controlo e regulação de comportamentos), uma melhoria do humor e uma diminuição dos níveis de stress. Por outro lado, confirma-se também que há áreas e circuitos no cérebro com são activados com “exercício agudo”. Uma das mudanças, explica Wendy Suzuki, será um aumento da produção de novos neurónios no hipocampo, uma área do nosso cérebro que regista o nosso passado e também ajuda a imaginar o futuro. Ou seja, há uma área com um papel importante na memória e criatividade que é activada e estimulada com exercício físico.

Apesar de não parecerem restar quaisquer dúvidas sobre os benefícios do exercício físico no comportamento das pessoas, as neurocientistas sublinham que a relação entre a prática de desporto e as mudanças neuroquímicas tem sido estudada sobretudo em modelos animais e, por isso, defendem que esta deve ser uma área de estudo para investir no futuro.

Citando:
"Broccoli contains an ingredient that can help those with type 2 diabetes control their blood sugar level, according to a new study – potentially providing a much-needed treatment option for millions.

A chemical in cruciferous vegetables like broccoli and sprouts called sulforaphane is thought to be responsible, having been shown to lower glucose levels in earlier lab experiments on diabetic rats."

Críticas ao estudo epidemiológico sobre as batatas fritas

Citando:
"Epidemiological studies often take groups of people of a certain age and observe how many of them die over a certain number of years. This can be useful in identifying the causes of premature mortality, but it does not tell us anything about our ‘chances of death’ which remain 100 per cent despite the best efforts of the health lobby.

Should we avoid chips on the basis of this study? I wouldn’t be too hasty. Published in the American Journal of Clinical Nutrition, it is a fairly average study by the standards of nutritional epidemiology. It does not have any glaring flaws that set it apart from the others, but that is not high praise. Most epidemiological studies are useless and nutritional epidemiology, in particular, is a cesspool of contradictory findings and confounding factors.

This is not the fault of the researchers (...)"

Óleo de côco, saudável ou não?

Questionando o óleo de côco e sobre os tipos de gorduras:

"Coconut oil is as unhealthy as beef dripping and butter, say US heart experts.

It is packed with saturated fat which can raise "bad" cholesterol, says the American Heart Association in updated advice.

Coconut oil is commonly sold as a health food and some claim the fat in it may be better for us than other saturated fats.

The AHA, however, says there are no good studies to support this.

The health benefits of coconut oil

Healthy Myth?

The advice around which fats to eat can be very confusing.

Animal fats, such as lard, are generally seen as bad, while plant oils, such as olive and sunflower, are seen as healthier options.

That theory is based on how much of one particular type of fat - saturated fat or "sat fat" - these products contain."
