Brócolos podem conter ingredientes importantes para combater a Diabetes tipo 2

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."

Ai as estatinas, outra vez

Agora fazem bem ao coração (contrabalançando os efeitos secundários, descritos no artigo e em outros artigos):
http://www.telegraph.co.uk/science/2017/05/26/statins-help-repair-heart-lowering-cholesterol-study-suggests/

Citando:
"Statins not only lower cholesterol but also repair the heart and restore lost function, a new study suggests.

Around six million people in Britain are prescribed statins but many people do not take the drugs over fears they caused debilitating side-effects.

Last year a 30-year study concluded that the benefits of statins far outweighed the risks and claimed they helped prevent around 80,000 heart attacks a year.

Now new research by Queen Mary University of London suggests they are even more beneficial. Not only do they lower cholesterol but they also appear to improve heart health.

The researchers suspect that the drugs reduce oxidative stress and so slows down heart ageing while at the same time boosting blood flow to help repair damage and lower stress.

The team used magnetic resonance scanning (MRI) to peer into the hearts of 4,622 men and women in their 60s from the UK Biobank, of whom 785 were taking statins.

Compared with untreated individuals, patients prescribed the medicines had lower left ventricular heart chambers containing 2.4 per cent less muscle mass, meaning their hearts were fitter and healthier and more able to pump blood effectively.

The effect was striking because those prescribed statins had been judged to the biggest risk of heart problems. They had higher BMIs, higher blood pressure and were on average four years older."

Secar a roupa dentro de casa é de evitar?

... Principalmente no Inverno e para quem tem alergias / asma:

"But hanging them to dry inside may be turning your house into an unhealthy breeding ground for different agents which thrive in damp places.

Dr Nick Osborne, Senior Lecturer in Environmental Health at the University of NSW, Australia told Kidspot that drying your clothes indoors contributed to the potential growth of mould and dustmites, both of which can be detrimental to your health.

It's particularly dangerous for people who suffer from asthma as it can trigger the symptoms.

Dr Christine Cowie, a senior research fellow at the University of New South Wales said:

"From a health perspective … many biological agents are found indoors and they usually thrive on dampness and inadequate ventilation. They have found that dampness itself has been a good indicator of risk of asthma and respiratory symptoms. There are other studies that show inhalation of fungal spores … are linked to allergic sensitisation and asthma, (...)""
