Amendoins (sem sal) podem ajudar na elasticidade das artérias

http://www.express.co.uk/life-style/health/785486/peanuts-boost-heart-health-prevent-attack-stroke

Citando:
"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.""

Relação ambiental e Alzheimer (alga na água)?

O marisco francês e o português parece conter a toxina (BMAA em Inglês) que está a ser associada ao aparecimento de Alzheimer:
http://www.express.co.uk/news/uk/637550/Alzheimer-s-scientists-cause-lurking-British-waters

Citando:
"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."
(...)
"Professor Cox said: "We think there is a gene-environment interaction. Perhaps some people are exposed to this toxin and, instead of excreting it, they accumulate it. If the genes are the gun, the toxin is the trigger."

They agreed more research was needed."

Relação de ELA (ALS) com exposição a radiação electromagnética

Estudo (observacional, amyotrophic lateral sclerosis):
https://www.newscientist.com/article/2126263-als-linked-to-occupational-exposure-to-electromagnetic-fields/

Citando:
"'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."

How having a hot steamy BATH is 'as good for your health as an hour-long sweaty workout'

Citando:
"Having a hot steamy BATH is ‘as good for your health as an hour-long sweaty workout’:

A relaxing bath can help lower blood sugar levels, and reduce disease-causing inflammation, experts have revealed"
(...)
"But, peak sugar level after eating was actually found to be 10 per cent lower in the participants who had a bath, compared with those who exercised.

Lead author Steve Faulkner wrote on The Conversation: “It seems that activities that increase heat shock proteins may help to improve blood sugar control and offer an alternative to exercise.

“These activities – such as soaking in a hot tub or taking a sauna – may have health benefits for people who are unable to exercise regularly."

Arroz e intoxicações alimentares?

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."

Citando:
"Researchers in the US have discovered that a protein called Ephexin5 may have a role in Alzheimer’s disease.

They discovered that removing Ephexin-5 in mice prevents the loss of connections between brain cells and prevented memory problems in mice with symptoms of Alzheimer’s disease. The researchers also discovered that Ephexin5 levels appear higher in the brain cells of people with Alzheimer's disease."

Sabíamos que fazia bem (Tetris)

... não sabíamos? Tetris ajuda a prevenir Stress pós-traumático (PTSD em Inglês) numa janela de 6 horas após o evento (exemplo um acidente):
http://nypost.com/2017/03/28/researchers-say-playing-tetris-can-prevent-ptsd/

Citando:
"Gamers who spend hours gazing at the falling pieces end up seeing them also in their thoughts and dreams – a phenomenon dubbed the “Tetris effect,” which can ease the impact of traumatic events.

Her team at the University of Oxford gave Tetris therapy to 71 volunteer patients at John Radcliff Hospital suffering from shock after traffic accidents. They were asked to visualize their accidents and then play the game on a Nintendo console.

After 20 minutes, disturbing memories of the events stopped being formed.

“Our findings suggest that if you engage in very visually demanding tasks soon after a trauma, this can help block or disrupt the memory being stored in an overly vivid way,” Holmes said.

There is a roughly a six-hour window of opportunity after a traumatic event for such an intervention to succeed, she noted."

Livros de culinária falham em termos de segurança alimentar

http://m.huffpost.com/uk/entry/uk_58da2b07e4b018c4606b213d

Citando:
"researchers specifically looked at three things:

Does the recipe tell readers to cook the dish to a specific internal temperature?

If it does include a temperature, is that temperature one that has been shown to be “safe”? For example, cooking chicken to 165°F (73°C).

Does the recipe perpetuate food-safety myths – such as saying to cook poultry until the juices “run clear” – that have “been proven unreliable as ways of determining if the dish has reached a safe temperature?”

The researchers found that only 123 recipes – 8% of those reviewed – mentioned cooking the dish to a specific temperature. And not all of the temperatures listed were high enough to reduce the risk of food-borne illness.

“In other words, very few recipes provided relevant food-safety information, and 34 of those 123 recipes gave readers information that wasn’t safe,” "
(...)
"Chapman called on cookbooks to help consumers make tasty food, but also to include relevant information to reduce our risk of getting sick.

“A similar study was done 25 years ago and found similar results – so nothing has changed in the past quarter century,” he said."

Estudo de Glioma identifica mais mutações associadas a Glioma

http://www.mirror.co.uk/lifestyle/health/brain-cancer-cure-hopes-breakthrough-10110854

Citação:
"The international study - the biggest genetic investigation of brain cancer ever conducted - analysed DNA data from more than 30,000 participants with and without glioma.

Results from two new genome-wide studies looking at a person’s entire genetic code were combined with findings from six previous studies.

Of the 13 previously unknown genetic changes linked to glioma, one increased the risk of developing the disease by a third and the rest by at least 15% each.

The mutations affected nerve cell multiplication, DNA repair, protein production, inflammation, and the “cell cycle” - the series of events leading to cell division."

Citando:
"With a chronic shortage of donor organs, researchers have resorted to engineering large-scale human tissue using techniques such as 3-D printing. One complex problem that has impeded this research, however, is how to recreate a small, intricate vascular system in order to deliver oxygen and nutrients required for proper tissue growth.

“One of the big problems in tissue engineering today is getting blood supply to the newly-created tissue,” Gaudette explained to CTVNews.ca in a phone interview from Worcester, Mass.

To overcome this problem, scientists have started looking at plants for a potential solution. Bioengineering researchers have begun experimenting with growing organs on different plants using their branching network of veins, which delivers water and nutrients to the leaves."

Redução no sal pode ajudar quem acorda para ir à casa de banho

http://www.bbc.com/news/health-39382339

Citando:
O que é sal a mais (no RU):
"Adults in the UK are recommended to eat no more than 6g of salt a day, equal to 2.4g of sodium.

Children should eat less - only 2g of salt for ages one to three, rising to 5g for seven to 10-year-olds.

After age 11, children can have up to 6g.

Which foods are high in salt?

Bread and breakfast cereals can contain more salt than you think.

Bacon, ham, cheese, crisps and pasta sauces are also high in salt.

When buying food, look at the figure for salt per 100g on the packaging.

High salt content is more than 1.5g salt (0.6g sodium) per 100g. These foods may be colour-coded red."

Sobre o estudo:
"They followed patients who had a high salt intake and sleeping problems for three months, after giving them advice to cut back on salt in their diet.

On average, trips to the loo fell from more than twice a night to just one.

This happened at night as well as during the day, and their quality of life also improved.

Feeling the urge

Conversely, 98 people in the study ended up eating more salt than normal and found they went to the loo more often at night-time.

(...)

"This work holds out the possibility that a simply dietary modification might significantly improve the quality of life for many people," he said."

Citando:
"For people with cancer, having it treated often brings with it a range of side effects which can be extremely debilitating.

Patients undergoing chemotherapy most commonly experience life-affecting side effects including fatigue, hair loss, weight loss, vomiting and nausea and memory and concentration problems.

One of the lesser known side effects is loss of taste. Many people undergoing the treatment suddenly find they can not enjoy the foods they usually do, or find that all food is tasting the same or that they cannot taste anything at all."
