"The study, published in the Journal of Nutrition, showed eating peanuts can keep the cells that line the arteries healthy - helping them stay more elastic.
The researchers showed when peanuts are eaten with a meal the typical build-up of triglycerides - like cholesterol a type of fat found in the bloodstream - is dampened.
Professor Kris-Etherton said: "After a meal, triglycerides increase and this typically decreases the dilation of the arteries, but the peanuts prevent that big increase in triglycerides after the meal.
"And that may be the mechanism behind this effect, because the triglycerides are not getting so high, which may explain why there is not a decrease in artery elasticity.""

"A toxin produced by the blue-green algae, also being linked to motor neurone disease (MND), has been discovered in plants and seafood and scientists fear it is contaminating the food chain and triggering the devastating brain diseases.
The algae, found in freshwater lakes and reservoirs throughout Britain, produces a toxin called BMAA, often as a by-product of its algal bloom.
The brains of people who have suffered from Alzheimer's and MND were found to contain high levels of BMAA and monkeys given a diet rich in the toxin developed Alzheimer's-like symptoms in less than five months.
If the link is confirmed between the toxin and humans, it would be the first major environmental factor linked to the increasing rate of Alzheimer's."

"Although a link to the food chain has not yet been established, seafood, including French mussels and oysters and Portuguese cockles grown in estuaries, have all been found to contain BMAA."

"'Jobs with relatively highe extremely low frequency electromagnetic fields levels include electric line installers, welders, sewing-machine operators, and aircraft pilots, says Vermuelen. “These are essentially jobs where workers are placed in close proximity to appliances that use a lot of electricity.”
Causal link?
The team have stressed that this study is observational – it has not proven that the fields themselves cause ALS, just that this factor is linked to a person’s likelihood of developing the disease.
However, it provides the best evidence yet that magnetic fields could be to blame for the disease. “This study has much better information on exposure to magnetic fields than previous studies,” says Pearce. “It shows that the increased risk of ALS in electrical workers is most likely due to magnetic field exposure, rather than to electrical shocks.”
But Christian Holscher, at Lancaster University, UK, says the results should be interpreted with caution. “The effect of extremely low frequency magnetic fields on ALS development is not clear,” he says. The study only just crosses the threshold for statistical significance, and because only 82 people in the analysis developed the disease, the finding may well be a false positive, he says."

O arroz (segundo o NHS) deve ser devidamente guardado e reaquecido apenas uma vez:
http://www.independent.co.uk/life-style/reheat-leftover-rice-food-poisoning-a7655816.html
Citando:
"So uncooked rice often contains spores (cells capable of reproducing quickly) of Bacillus cereus — a bacteria strand that can cause food poisoning — that can survive when rice is cooked.
And if the rice is left standing at room temperature after it's been boiled, the spores can grow into bacteria, which will ultimately multiply and may produce toxins that cause vomiting or diarrhea.
The longer cooked rice is left at room temperature, the more likely it is that the bacteria will make the rice unsafe to eat — meaning it's vital that you store your rice at the right way quickly if you're hoping to reheat it later.
So, how do you increase the chances of avoiding food poisoning all together? First off, serve rice as soon as it's been cooked, and cool any leftovers as quickly as possible. The NHS recommends within an hour, ideally. You can then keep the rice in the fridge (but for no more than one day) before reheating."

"Marathon running can drastically change your body, and mostly in a good way.
The benefits of long-distance running include boosting your mood and longevity while reducing your risk of cancer, diabetes and obesity.
Yet, running 26.2 consecutive miles also can stress the body, leading to injury risk, a momentarily weakened immune system, and now a small study suggests acute kidney injury, too.
Marathon runners can develop short-term kidney injury during a race, but the kidneys repair themselves within about two days, according to the study, which published in the American Journal of Kidney Diseases on Tuesday.
(...)
The researchers found higher-than-normal levels of creatinine in the urine and blood samples of almost all of the runners immediately after the marathon, with 82% of the runners showing signs of at least stage 1 acute kidney injury.
(...)
About a day and a half after the marathon, samples again were collected, and they no longer showed signs of acute kidney injury.
(...)
The kidneys are temporarily impacted during marathon running for various reasons, one being that some of the blood supply kidneys typically receive is being pumped to the body's muscles instead of the organ, Parikh said.
"When someone runs 26 miles, the blood supply to the skin and muscle increases tremendously, because they need a lot of oxygen," he said. "It's estimated that up to 25% of blood ends up going to skin and muscle, and when this happens, that means the blood is getting diverted from other organs. So, while the skin and muscle are perfused at a higher rate, the kidneys are receiving a reduced blood supply."
(...)
"What we saw in our study was that if people didn't train very much and they were sort of new to marathon running they had a lot more leakage of heart enzymes and it's a lot harder on their bodies because they haven't been chronically exposed to the conditions imposed by prolonged exercise," Wood said. "Prolonged endurance exercise increases bloodflow to the leg muscles but can shunt blood away from the gut and kidneys."
Therefore, adequate training is key to minimizing any potentially harmful impacts marathon running can have on the body, she said."

Fertilizantes sintéticos
Além da água, as plantas precisam de nutrientes e oligoelementos para crescer de acordo com padrões de alta qualidade. Fertilizantes com os nutrientes exatos são essenciais para garantir a fertilidade do solo, diz a agência federal alemã de meio ambiente (UBA).
No entanto, há uma distinção importante entre fertilizantes orgânicos e fertilizantes minerais ou sintéticos. Os fertilizantes podem acabar contribuindo para o aquecimento global devido à grande quantidade de energia necessária para sua produção e o gás de óxido nitroso (N2O) que é liberado quando degradado no solo, revela o estudo.
Os números podem ajudar a entender o problema. O óxido nitroso é um gás de efeito estufa que provoca 300 vezes mais danos ao clima do que o dióxido de carbono (CO2). Juntamente com o metano, o óxido nitroso constitui cerca de um quarto do aquecimento global – e é liberado principalmente através da agricultura industrial.

Whoa: That doesn’t mean most cases of cancer are due solely to “bad luck.” It takes multiple mutations to turn cells into tumors — and a lot of cancer is preventable, the Hopkins team stressed, if people take proven protective steps.

These included the frontal cortices -- which handle movement, problem solving, memory, language, judgement and impulse control -- the prefrontal cortices -- complex behaviours, planning, personality -- parietal cortices -- integrating sensory input -- temporal lobe -- hearing and selective listening -- and the brainstem -- controlling cardiovascular and respiratory functions.

"The drug, Repatha, is called a PCSK9 inhibitor and can make cholesterol tumble to levels almost never seen naturally in adults, or even in people taking cholesterol-lowering statins. The Amgen drug and a similar one, sold by Sanofi and Regeneron, were approved by the Food and Drug Administration in 2015 with the hope — and expectation — that they would lower the risk of heart attacks and strokes, and not just reduce levels of LDL cholesterol, the dangerous kind.
That hope has now been realized for the Amgen drug."

"A retina é uma membrana localizada no segmento posterior do globo ocular e suas células receptoras têm como função converter imagens e estímulos luminosos em impulsos elétricos a serem processados pelo cérebro. Doenças degenerativas, como a retinose pigmentar, matam estas células, causando uma perda progressiva da visão.
Como as doenças degenerativas retinais não danificam os nervos oculares próximos à retina, o implante desenvolvido em laboratório funcionou perfeitamente, possibilitando a conversão de estímulos luminosos em sinais elétricos capazes de serem decodificados pelo cérebro.
O implante é constituído por uma fina camada de um polímero condutor sustentado por uma base e revestido com um polímero semicondutor, sendo este último responsável por captar fótons quando os olhos absorvem luz. Quando isso ocorre, estímulos elétricos acionam os neurônios retinais, corrigindo as falhas na retina danificada."

"He said: "Allowing these drugs to be purchased without a prescription, and without any advice or restrictions, sends a message to the public that they must be safe.
"The findings are a stark reminder that NSAIDs are not harmless.
"Diclofenac and ibuprofen, both commonly used drugs, were associated with significantly increased risk of cardiac arrest.
"NSAIDs should be used with caution and for a valid indication. They should probably be avoided in patients with cardiovascular disease or many cardiovascular risk factors."
(...)
"The most common cause of a cardiac arrest is a life-threatening abnormal heart rhythm called ventricular fibrillation (VF).
It causes electrical activity in the heart to become so chaotic that the organ ceases to pump rhythmically and quivers or "fibrillates" instead. Without immediate treatment to keep the circulation going, death occurs in minutes.
Sales of over-the-counter painkillers amounted to almost £600 million in the UK in 2015, according to The Pharmaceutical Journal."

"He commented: “Eating food that has spent a few moments on the floor can never be entirely risk free.
"Obviously, food covered in visible dirt shouldn’t be eaten, but as long as it’s not obviously contaminated, the science shows that food is unlikely to have picked up harmful bacteria from a few seconds spent on an indoor floor.
“That is not to say that germs can’t transfer from the floor to the food.
"Our research has shown that the nature of the floor surface, the type of food dropped on the floor and the length of time it spends on the floor can all have an impact on the number that can transfer.”"
De vez em quando aparece um estudo ou uma opinião contrária ao (que se tornou) senso comum: que o orgânico é muito mais saudável e que é uma agricultura mais sustentável (mas pelos vistos utiliza mais terreno cultivável - menor produtividade por metro quadrado).
Pior ainda: os alimentos sendo muito mais caros não são (de acordo com este artigo) necessariamente isentos de pesticidas (há os naturais), são mais perecíveis (tendo de ser recolhidos mais cedo quando não vendidos), são maior fonte de intoxicação (por por exemplo E. Coli) e são apenas marginalmente mais nutritivos:

She added: ‘While an organic farm may be better for things like biodiversity, farmers will need more land to grow the same amount of food.
‘And land conversion for agriculture is the leading contributor to habitat loss and climate change.’

"Perhaps the most shocking is that organic farms use pesticides – and sometimes use ones which are more toxic than the ones used by ‘normal’ farms.
(...) organic farmers can still use pesticide, they just can’t be synthetically made – and some natural pesticides are a more serious health and environmental risk than synthetic ones. Natural doesn’t always mean better.
Previous reports have highlighted the risks of toxic copper sulfate – used by some organic vegetable growers.
Organic food is alo more likely to give you food poisoning, according to ASAP science – with one study suggesting that up to 10% had traces of food poisoning bacteria E Coli.
ASAP Science says, ‘Organic food has a higher incidence of product recalls. On average 1% of food products are recalled – but 7% of organic products.’
There’s also little evidence that organic food is actually better for you – although it’s often up to 47% more expensive, according to Consumer Reports.
A 2012 Stanford study analysed 237 previous studies of organic foods and found that most here, ‘no more nutritious than conventionally grown foods’"

"While past research has suggested identifying and avoiding foods or drinks that trigger symptoms, altering the amount of fibre in your diet, and regular exercise can help relieve symptoms, a new probiotic, called Alflorex, is believed to be an effective solution.
A result of more than 15 years of clinical research and 75 leading scientific publications, Alflorex contains a probiotic strain called B. infantis3564 which specifically targets and alleviates the symptoms of IBS.
It was recently launched in the UK - the strain is known in the US as Align - is has been recommended as the number one probiotic for the treatment of IBS by gastroenterologists.
Professor Eammon Quigley, one of the world’s leading Gastroenterologists in IBS and Chief of Gastroenterology at Houston Methodist Hospital, told Healthista: “The gut bacteria plays an important role in many digestive health issues.
“B.infantis 35624, the strain in Alflorex, is one of the few products that has been truly developed on a scientific basis and tested in high quality clinical studies to hep the symptoms of IBS.”"

"Inverse association
What the Harvard group behind this study have reported is that there is an inverse association between gluten intake and type 2 diabetes risk. This means that the less gluten found in a diet the higher the risk of developing type 2 diabetes.
The data for this exciting finding comes from three separate, large studies which collectively included almost 200,000 people. Of those 200,000 people, 15,947 cases of type 2 diabetes were confirmed during the follow-up period. Analysis showed that those who had the highest intake of gluten had an 80% lower chance of developing type 2 diabetes compared to those who had the lowest levels of gluten intake.
This study has important implications for those who either have to avoid or choose to avoid gluten in their diet."
(...)
"While there is some evidence for a link between coeliac disease and type 1 diabetes, this is the first study to show a link between gluten consumption and the risk of type 2 diabetes. This is an important finding. For those who choose a gluten-free diet because they believe it to be healthy, it may be time to reconsider your food choices."

"Pelling e a sua equipa removeram as células e o ADN de uma maçã, até sobrar apenas a sua estrutura de celulose, a substância responsável por deixar a fruta crocante.
Existente na maioria dos vegetais e de característica fibrosa, a celulose é responsável por dar rigidez e firmeza às plantas e não é digerida pelos seres humanos.
Os cientistas constataram, então, que esta estrutura mostrou-se eficaz para o implante de células vivas em laboratório, incluindo as células humanas.
Posteriormente, a equipa esculpiu maçãs em formato de orelha e usou estes “esqueletos” de celulose para implantar neles células humanas."

Níveis de cortisol elevado (por stress prolongado) podem levar a excesso de peso ou será ao contrário (R: não se sabe ainda)? E pode-ser ser obeso e viver mais que pessoas com IMC mais saudável (R: aparentemente sim):
https://www.theguardian.com/lifeandstyle/2017/mar/06/is-it-possible-to-be-healthy-and-obese-stress
Citando:
" Long-term stress raises cortisol levels, and the researchers found that the larger volunteers had higher levels in their hair. So does this mean we can attribute obesity to stress and, if so, what can we can do about it?
The idea itself isn’t new. Cortisol is produced by the adrenal glands that sit on top of the kidneys. It plays a vital role in keeping glucose levels in the bloodstream in a steady state. When we are stressed or threatened, cortisol levels rise to release more glucose from stores in the liver, so we have more fuel to fight or run for our lives. Too much cortisol means too much glucose floating around and if it doesn’t get used, the excess is stored as fat."
(...)
Algumas perguntas ainda por responder:
"Is the raised cortisol a cause or an effect of obesity? Will lowering levels prove an effective treatment? And will we ever be able to stem the rising tide of obesity? Furthermore, is it actually that bad to be fat? Some might point to a studyshowing that older people who are overweight (BMI 25-30) live longer than those of normal weight and that the optimal BMI is 27. What they don’t say is that many of those will tip into being obese (a BMI of more than 30) as time goes on. "

"After an in-depth review of the scientific data, researchers found the most heart-healthy diet includes foods like extra-virgin olive oil, antioxidant-rich berries, green leafy vegetables, plant-based proteins, nuts in moderation and can include lean meats. To cut down on cholesterol, the study authors suggest limiting or eliminating coconut and palm oils, which are high in saturated fatty acids, and eggs, which raise the level of cholesterol in the bloodstream.
"Dietary requirements haven’t really changed," Freeman continued. "The diet that is most cardioprotective is mostly plant based ... predominantly fruits, vegetables, whole grains, and limited amounts of animal products if any.""

"The most critical group of all includes multidrug resistant bacteria that pose a particular threat in hospitals, nursing homes, and among patients whose care requires devices such as ventilators and blood catheters. They include Acinetobacter, Pseudomonas and various Enterobacteriaceae (including Klebsiella, E. coli, Serratia, and Proteus). They can cause severe and often deadly infections such as bloodstream infections and pneumonia.
These bacteria have become resistant to a large number of antibiotics, including carbapenems and third generation cephalosporins – the best available antibiotics for treating multi-drug resistant bacteria.
The second and third tiers in the list – the high and medium priority categories – contain other increasingly drug-resistant bacteria that cause more common diseases such as gonorrhoea and food poisoning caused by salmonella."
