A percepção dos efeitos do álcool mudou muito em 20 anos e o RU alterou radicalmente as suas linha orientadoras de consumo (em Janeiro de 2016) para 14 volumes de álcool por semana, uma das mais restritivas na Europa. Detalhes da decisão e das quantidades recomendadas:
http://www.bbc.com/news/uk-35252650
Citando:
"The review found that the benefits of alcohol for heart health only apply for women aged 55 and over - and even then it's in very small amounts, around five units a week.
The guidelines say: "There is no justification for recommending drinking on health grounds - nor for starting drinking for health reasons."
It also says that evidence in support for drinking alcohol in small amounts to maintain good health was "weaker than it was at the time of 1995"."
(...)
Is there a safe drinking level?
No. The new recommendations are at pains to point out that these guidelines are not for "safe" drinking, but rather just at minimising risk of illness.
All alcohol consumption carries some risk, the guidance says.
"The vast majority of the population can reduce health risks further if they reduce drinking below the guideline levels, or do not drink at all," the guidance says.
Drinking above the new recommended 14 units a week is the point at which a person's risk of an early death increases by 1% - the equivalent amount of risk as driving a car."
PS. Muito interessante a tabela com os limites de diversos países (Espanha, 38; RU, 14). Se a ciência e investigação é a mesma, porque é que não há consenso nos limites, nem sequer na Europa?

Prós e contras do leite não pasteurizado explicados
Beneficios (e riscos) do leite não pasteurizado:
Raw Milk: Health Benefits And Safety Concerns Explained | The Huffington Post
Resumidamente se não se ferver (pasteurização é ferver por algumas horas o leite) o leite tem mais propriedades boas (vitaminas e não só). Mas tem um tempo de vida muito curto e pode estar contaminado com E. Coli e outras bactérias nocivas para a saúde. Detalhes completos no artigo acima.

Síndrome do Coração Partido (takotsubo)?
Mãe da princesa Leya do Star Wars, poderá ter morrido de Síndroma do coração partido:
http://www.dailymail.co.uk/wires/ap/article-4076448/Did-Debbie-Reynolds-die-broken-heart-syndrome.html
Citando:
"Broken-heart syndrome is when a surge of stress hormones, such as adrenaline and cortisol, cause arteries to seize, limiting blood flow to the heart. The experience — and diagnosis — is often confused with heart attack, Creager said.
Both conditions look the same on an electrocardiogram, said cardiologist Dr. Holly Andersen, director of education for the heart institute at New York Presbyterian Hospital and scientific adviser for the Women's Heart Alliance. But where heart attacks are caused by blocked arteries, there are no such blockages in "broken" hearts.
The condition can be treated, and even heal untreated, she said, but it can also cause heart arrhythmias and sudden death.
Japanese researchers were the first to describe broken-heart syndrome in 1990. They named it takotsubo, which means "octopus pot," for the way the malfunctioning heart appears in imaging studies."

A ciência à volta dos... peidos, perdão, gases!
Há todo o tipo de ciência. A boa e a má. E há até a ciência dos peidos: Porque é que alguns cheiram mal que tresandam (e o que é que se pode fazer para minimizar o mau cheiro).
Isto é boa ciência, a bem dos teus amigos e companheiros(as):
This is why some of your farts smell MUCH worse than others - and how to make them less pongy
Citando:
"Thankfully there is a way to counteract the effects of cysteine, to an extent.
According to gastroenterology, nutrition and dietetics expert Chu Yao at Monash University in Melbourne, Australia, starchy foods act as a resistant to hydrogen sulphide gas.
They can reduce the production of it by up to 75 per cent, so even if you’ve a protein-rich diet, you should be able to limit the active sulphide gases in your stomach.
Starch-rich foods that are resistant to hydrogen sulphide gas include potatoes, bananas, cereals and artichokes.
Foods that are resistant to hydrogen sulphide gas (starchy foods):
Potatoes [in PT: Batatas]
Bananas
Legumes
Cereals
Artichokes [alcachofra]
Asparagus [aspargos]
Fructans (found in wheat) [frutano]
These foods are broken down before the proteins as they are highly fermentable, meaning “the focus is taken away from the protein, so hydrogen sulphide is not produced”, according to Yao, who presented the group’s findings at at a Gastroenterological Society of Australia conference in Adelaide."

Researchers found that the reason some farts are eye-wateringly foul is because the gas contains cysteine, a component present in meat, dairy, eggs and other types of protein.
When you eat the foods containing cysteine, it multiplies the amount of hydrogen sulphide gas – the odour ogre – in your tummy by seven."

- Fantastic Voyage: Live Long Enough to Live Forever by Ray Kurzweil — Reviews, Discussion, Bookclubs, Lists (by Ray Kurzweil, Terry Grossman)
Citando:
“REPROGRAMMING MY BIOCHEMISTRY A common attitude is that taking substances other than food, such as supplements and medications, should be a last resort, something one takes only to address overt problems. Terry and I believe strongly that this is a bad strategy, particularly as one approaches middle age and beyond. Our philosophy is to embrace the unique opportunity we have at this time and place to expand our longevity and human potential. In keeping with this health philosophy, I am very active in reprogramming my biochemistry. Overall, I am quite satisfied with the dozens of blood levels I routinely test. My biochemical profile has steadily improved during the years that I have done this. For boosting antioxidant levels and for general health, I take a comprehensive vitamin-and-mineral combination, alpha lipoic acid, coenzyme Q10, grapeseed extract, resveratrol, bilberry extract, lycopene, silymarin (milk thistle), conjugated linoleic acid, lecithin, evening primrose oil (omega-6 essential fatty acids), n-acetyl-cysteine, ginger, garlic, l-carnitine, pyridoxal-5-phosphate, and echinacea. I also take Chinese herbs prescribed by Dr. Glenn Rothfeld. For reducing insulin resistance and overcoming my type 2 diabetes, I take chromium, metformin (a powerful anti-aging medication that decreases insulin resistance and which we recommend everyone over 50 consider taking), and gymnema sylvestra. To improve LDL and HDL cholesterol levels, I take policosanol, gugulipid, plant sterols, niacin, oat bran, grapefruit powder, psyllium, lecithin, and Lipitor. To improve blood vessel health, I take arginine, trimethylglycine, and choline. To decrease blood viscosity, I take a daily baby aspirin and lumbrokinase, a natural anti-fibrinolytic agent. Although my CRP (the screening test for inflammation in the body) is very low, I reduce inflammation by taking EPA/DHA (omega-3 essential fatty acids) and curcumin. I have dramatically reduced my homocysteine level by taking folic acid, B6, and trimethylglycine (TMG), and intrinsic factor to improve methylation. I have a B12 shot once a week and take a daily B12 sublingual. Several of my intravenous therapies improve my body’s detoxification: weekly EDTA (for chelating heavy metals, a major source of aging) and monthly DMPS (to chelate mercury). I also take n-acetyl-l-carnitine orally. I take weekly intravenous vitamins and alpha lipoic acid to boost antioxidants. I do a weekly glutathione IV to boost liver health. Perhaps the most important intravenous therapy I do is a weekly phosphatidylcholine (PtC) IV, which rejuvenates all of the body’s tissues by restoring youthful cell membranes. I also take PtC orally each day, and I supplement my hormone levels with DHEA and testosterone. I take I-3-C (indole-3-carbinol), chrysin, nettle, ginger, and herbs to reduce conversion of testosterone into estrogen. I take a saw palmetto complex for prostate health. For stress management, I take l-theonine (the calming substance in green tea), beta sitosterol, phosphatidylserine, and green tea supplements, in addition to drinking 8 to 10 cups of green tea itself. At bedtime, to aid with sleep, I take GABA (a gentle, calming neuro-transmitter) and sublingual melatonin. For brain health, I take acetyl-l-carnitine, vinpocetine, phosphatidylserine, ginkgo biloba, glycerylphosphorylcholine, nextrutine, and quercetin. For eye health, I take lutein and bilberry extract. For skin health, I use an antioxidant skin cream on my face, neck, and hands each day. For digestive health, I take betaine HCL, pepsin, gentian root, peppermint, acidophilus bifodobacter, fructooligosaccharides, fish proteins, l-glutamine, and n-acetyl-d-glucosamine. To inhibit the creation of advanced glycosylated end products (AGEs), a key aging process, I take n-acetyl-carnitine, carnosine, alpha lipoic acid, and quercetin.

Tècnica que pode ajudar a prevenir a "depressão Natalícia" (família não se escolhe)
A depressão Natalícia por problemas de relação com a família (e outras de natureza confrontacional), pode aparentemente ser combatida (ou a resiliência a esses eventos pode ser aumentada) com uma técnica simples de revisão do que foi visto, ouvido, sentido e cheirado durante o evento stressante (e o que aconteceu em sequência), técnica essa que supera a consulta com um médico:

"The research involved a six-week trial with patients suffering from clinical depression, during which they were trained to spot warning signs for stress, and then review stressful situations they had been in, focusing particularly on what could be seen, heard, felt, smelled and the sequence of what happened.
Results showed it reduced symptoms of depression, outperforming the usual treatment from the GP alone, the psychologists said.
Prof Watkins added: "We have found in the lab that when people train themselves to think about the specific sensory details, context and sequence of an emotional event, including how it unfolded, they were more emotionally resilient to an unexpected stressor than those who thought about the meaning and implications of emotional events."

Quanto tempo esperar depois de beber para conduzir?

Citando:
"How many units does a drink contain?
There is still confusion over this, but the NHS says there is roughly:
175ml glass of wine of average strength (12%) - 2.1 units
250ml glass of wine of average strength (12%) - 3 units
One pint of low-strength lager, beer or cider (3.6%) - 2 units
One pint of high-strength lager, beer or cider (5.2%) - 3 units
One single measure of spirits - 1 unit
How much alcohol is it safe to drink each week?
The Chief Medical Officers' (CMO) guideline for both men and women states that:
•To keep health risks from alcohol to a low level it is safest not to drink more than 14 units a week on a regular basis
•If you regularly drink as much as 14 units per week, it's best to spread your drinking evenly over three or more days. "

"It takes us an hour to metabolise one unit of alcohol," the doctor reminds us. So if you were drinking until 2am and had along the lines of a bottle and a half of wine - roughly 15 units - that will take 15 hours to completely remove itself from your system. If you start drinking again the next day, your body hasn't even finished metabolising last night's alcohol before it can start on the new influx, so you get drunk quicker.

Citando:
"Their conclusion does not provide much of a jolt: Eating protein is related to satiety in the short term, they say. Even “modestly higher” amounts of protein may help you feel fuller between meals, though the team could not determine an actual formula, say grams of protein per BMI for men or women. They also say it’s unclear if the results hold up over the long term or if, say, your body gets used to the added protein.
However, if you’d like to put this into practice — if you’re on a diet and scaling back on calories and don’t want to feel hungry — the researchers suggest you eat additional protein in small increments as a first step. Protein-rich foods consist of dairy (eggs, milk, and yogurt), meat (steak, pork chops, lamb), fish (tuna, salmon, halibut, octopus), fowl (chicken and turkey), legumes (beans, peanuts, and lentils) and some grains (wheat germ and quinoa)."

"A clinical trial has shown that a new, non-surgical method of treatment for low-risk prostate cancer can effectively kill cancer cells whilst at the same time preserving healthy tissue.
The new treatment is called vascular-targeted photodynamic therapy, or VTP. According to University College London Hospitals (UCLH), the treatment uses a light-sensitive drug, which is injected into the bloodstream. A laser then activates the drug, which eradicates tumour tissue in the prostate.
The drug used is called WST11 and comes from bacteria found at the bottom of the ocean. These bacteria have evolved to turn light into energy in a very efficient way. This trait has been exploited to develop WST11, which UCLH describes as “a compound that releases free radicals to kill surrounding cells when activated by laser light.”"

Correr descalço não previne lesões?
Aparentemente afinal não ajuda à prevenção de lesões (é "apenas" mais um tipo de corrida):

Citando:
"Nigg and Enders started by investigating the effects of barefoot running on foot motion. Proponents of minimalist running often claim that running without shoes decreases the risk of injuries by promoting landings near the front of the feet, near the toes, instead of landing on the heel purportedly more likely with standard shoes.
Their research suggests that this claim is unfounded and that "it is not appropriate to associate barefoot running with toe landing and shod running with heel landing," because factors like surface, shoe type, running speed, and individual differences are too variable to consistently make the links."

NHS está a pensar recomendar exame ao fígado para prevenir cirrose
A cirrose quando apresenta sintomas já está em estado adiantado. O SNS do RU está em vias de recomendar um exame médico que detecte alterações precocemente (não invasivo, alternativa a biópsia):
http://www.bbc.com/news/health-38364331
Citando:
"Dr Andrew Fowell, liver expert at the Portsmouth Hospitals NHS Trust, said: "Identifying people who are at risk of liver disease and offering them non-invasive testing to diagnose cirrhosis is key to ensuring they are given the treatment and support they need early enough to prevent serious complications.
"Ten years ago diagnosis of cirrhosis would often require a liver biopsy, but now with advances in non-invasive testing it is much easier for patients and health professionals to make a diagnosis."
The draft quality standard from NICE recommends a non-invasive scan called transient elastography which uses ultrasound and low-frequency elastic waves to check the liver. A consultation on the draft document is open until February 2017."
Sobre os limites: 5 garrafas de vinho/semana (50 volumes) ou 3,5 para as senhoras.

"Women who regularly drink more than three-and-a-half bottles of wine a week should get their livers checked, says new draft advice for England.
For men, the threshold is five bottles of wine a week or 50 units of alcohol, says the National Institute for Health and Care Excellence.
The organisation says GPs should refer "harmful" drinkers for liver scans.
Cirrhosis can be silent until the damage becomes so extensive it stops the liver working."

Citando:
"Women who take paracetamol or ibuprofen just twice a week could be damaging their hearing permanently," the Daily Mail reports.
A US study found an association between the long-term use of these widely used painkillers and reported hearing loss.
Researchers calculated just over 1 in 20 (5.5%) hearing loss cases in their study could have been the result of painkiller use.
But they say it's not possible for this study to prove the drugs caused the hearing problems.
Previous studies have linked aspirin, paracetamol, and non-steroidal anti-inflammatory drug (NSAID) types of painkiller, such as ibuprofen, with hearing loss."

Fazer exercício físico em cidades poluídas pode fazer mais mal do que bem (pulmões e coração) - Estudo

Air pollution is measured in particulate matter (PM) - coarse dust particles which get into the lungs.
In London more than 3,000 deaths a year are attributed to particulate matter in the air and earlier this week it was revealed that three of the wealthiest boroughs had the highest rates of death caused by dirty air.
Despite a World Health Organisation recommendation that air pollution levels should not exceed a particulate matter rating of 2.5 micrometers at a maximal daily mean, cities worldwide regularly exceed the rating.
It was also found that patients with obstructive sleep apnoea - where the walls of the throat narrow during sleep - are most at risk."

“The very high intake of total and saturated fat did not increase the calculated risk of cardiovascular diseases,” says professor and cardiologist Ottar Nygard."

It's based on the idea, supported by previous studies, that high doses of testosterone can interfere with cancer cell division in some cases, and actually cause some cancer cells to make breaks in their own DNA."
Nestlé diz que vai reduzir em 40% o açúcar do chocolate
O que é bom para a saúde de quem os comer e óptimo para a sua saúde financeira (a alteração da estrutura do açúcar será patenteada):
http://www.bbc.com/news/business-38167241
"The Swiss food giant, Nestle, says it has made a scientific breakthrough that can sharply cut the sugar in its chocolate.
The company, which makes Kitkat and Aero, says its researchers have found a way to structure sugar differently, so that it uses 40% less.
It claims this can be done without affecting the taste.
Nestle says it is patenting the findings, and it would start using the new sugar across its range from 2018.
Its scientists altered the structure of sugar so that it dissolves more quickly."
(...)
"Other food companies have made technological breakthroughs with ingredients. Six years ago, PepsiCo, which owns the Walkers crisp brand, developed a designer salt molecule that it said would allow it to use less sodium without affecting taste."

Impacto do desporto na redução da mortalidade: O ténis é desporto rei?
Um estudo (algo limitado) sobre o impacto do desporto na redução da mortalidade foi publicado. Análise do SNS do RU:
http://www.nhs.uk/news/2016/11November/Pages/Want-to-live-longer-Try-racquet-sports-recommends-study.aspx
Citando:
"A study looking at the impact of individual sports on mortality found racquet sports reduced the risk of death by around 47%.
Researchers also found reduced risks of death for people who took part in cycling, swimming and aerobics.
They didn't find such effects for people who took part in rugby, football or running – although this unexpected finding may be explained by the low number of deaths, which may have skewed the statistics. The smaller the data set, the bigger the chance of the data being influenced by chance.
While the researchers found taking part in some sports reduced the risk of death compared to not taking part, they did not directly compare the benefits of different sports. That means we can't say which sport is "best" for health.
What is clear from the study is that any sort of regular physical activity is likely to help us stay healthier and live longer."
(...)
The study was carried out by researchers from the UKK Institute in Finland, University of Edinburgh, University of Oxford, Loughborough University and University of Exeter in the UK, Victoria University and University of Sydney in Australia, and University of Graz in Austria. No information about funding was provided."

Machismo e problemas psicológicos?
http://m.scmp.com/news/article/2048580/playboy-type-men-have-higher-risk-psychological-problems-study-suggests
Citando:
"Psychologists looking at 10 years of data from nearly 20,000 men found that those who value having power over women and endorse playboy-type behaviour and other traditional notions of masculinity are more likely to suffer from psychological problems - and less likely to seek out help.
The new meta-analysis, which was published Monday in the Journal of Counseling Psychology, synthesised 78 studies on masculinity and mental health gathered between 2003 and 2013. The participants ranged in age from 12 to over 65, and the vast majority were men. A little more than half of the studies involved predominantly white men, though some focused on African Americans or Asian Americans. Most of the studies didn’t ask respondents’ sexual orientation, but among those that did, most of the participants were straight.
Researchers then identified 11 norms considered to be “traditionally masculine” - desire to win, need for emotional control, risk-taking, violence, dominance, sexual promiscuity or playboy behaviour, self-reliance, primacy of work, power over women, disdain for homosexuality and pursuit of status - and looked to see if they were associated with particular mental health outcomes."

Rejuvenescimento por tratamento do sangue - Calico | Google
Vão começar os ensaios clínicos (por 6 meses) de um tratamento altamente experimental depois de resultados em animais mostrarem resultados muito promissores (rejenuvestimento):

"People who take part in the trial will have their blood passed through a machine that resets abnormal levels of proteins seen in older blood. The scientists believe these high levels of certain proteins can hamper the growth and maintenance of healthy body tissues, and so contribute to their deterioration in old age.
Plans for the trial emerged as scientists announced the results of the animal study, which was part-funded by Calico, Google’s life extension company. The study showed that infusions of old blood reduced the growth of fresh liver and brain cells in young mice and impaired their performance in a strength test.
The same series of experiments found evidence that infusions of young blood could speed up muscle repair in older animals."

Os benefícios (e os perigos) de correr em jejum
http://www.correrporprazer.com/2015/06/correr-em-jejum/
Citando:
"A ideia de quem procura os treinos cardiovasculares (corridas ou caminhadas) em jejum é aproveitar o período em que as reservas de açúcar estão baixas para estimular a queima de gordura mais cedo no treino. “A questão é que o nosso cérebro consome preferencialmente açúcar e, na ausência deste, vamos obrigar o nosso corpo a produzir corpos cetónicos. Prolongando este quadro podemos causar cetose, elevando a acidez do sangue”, defende o ‘personal trainer’ e professor de capoeira António Braz, lembrando que a acidose prolongada pode ter efeitos nefastos.
Henrique Jones, ex-médico da seleção portuguesa de futebol, considera que uma refeição ligeira uma hora antes do exercício “é fundamental para preencher as reservas energéticas que permitem alimentar os músculos”."

Citando:
"Your day might be filled with irritatingly hot temperatures, thick air pollution and maybe even pockets of rainclouds, but that won’t necessarily get you down. If you’re able to soak up enough sun, your level of emotional distress should remain stable. Take away sun time, though, and your distress can spike. This applies to the clinical population at large, not just those diagnosed with Seasonal Affective Disorder.
“That’s one of the surprising pieces of our research,” said Mark Beecher, clinical professor and licensed psychologist in BYU Counselling and Psychological Services. “On a rainy day, or a more polluted day, people assume that they’d have more distress. But we didn’t see that. We looked at solar irradiance, or the amount of sunlight that actually hits the ground. We tried to take into account cloudy days, rainy days, pollution . . . but they washed out. The one thing that was really significant was the amount of time between sunrise and sunset.”"

Cozinhar acima dos 150 graus?
https://www.eurekalert.org/pub_releases/2016-11/uoe-ctm110216.php
Citando:
"Cooking food at temperatures above 150 degrees centigrade changes their chemical structure and can lead to the formation of toxic products known as neo-formed contaminants (NFCs).
These include trans-fatty acids - which are known to be harmful and are banned from food sold in many parts of the world - and other toxins called advanced glycation end-products.
Frying foods at a high heat is particularly problematic because the oils readily break down to form trans-fatty acids.
An international team - led by the University of Edinburgh - reviewed previous studies that have investigated the effects of NFCs on human and animal tissue. The studies explored the relationship between these products and heart disease risk.
Their findings revealed that cooking methods - including frying and roasting - which are common in South Asian countries created high levels of trans-fatty acids, especially if the oil is reused."

http://www.telegraph.co.uk/science/2016/11/02/sleep-deprivation-feeds-hunger-around-four-extra-slices-of-toast/
Citando:
"This study found that partial sleep deprivation resulted in a large net increased energy intake of 385 kcal per day.
If long-term sleep deprivation continues to result in an increased calorie intake of this magnitude, it may contribute to weight gain."
Dr Pot added: "Reduced sleep is one of the most common and potentially modifiable health risks in today's society in which chronic sleep loss is becoming more common.""

Os níveis de PSA e os exames e intervenções à próstata
Um relato em primeira-mão de uma história que começou com níveis de PSA elevados (testados por análises ao sangue):
http://m.huffpost.com/uk/entry/12751516
Citando:
"[I] had a PSA level of 16. Now, PSA (prostate specific antigen, measured in nanograms per millilitre of blood) can give both false negatives and false positives. Normal levels of PSA in the blood are between 0-2.5 ng/ml. Higher than normal levels, greater than 2.5, can be caused by cancer or by benign, non-cancerous conditions such as an enlarged prostate, prostate inflammation, infection, or trauma. But all elevated readings of PSA should be investigated."

Superbugs e ingrediente desinfectante
Quando uma coisa que se destina a resolver um problema, cria outro:
Citando:
"A laboratory study found the ingredient chlorhexidine, used in a wide range of antiseptic products, increased bacterial resistance to the antibiotic colistin.
Despite the headline to the contrary, researchers did not specifically test mouthwash or any other household products.
Colistin is what is known as an "antibiotic of last resort" and is used to treat Klebsiella pneumoniae bacterium that has evolved resistance to other more widely used antibiotics."

Composto NMN existente em verduras pode ser o elixir da juventude
Encontram-se nos brócolos, abacates, couves, etc..
As novidades são que vão começar ensaios em humanos e que as quantidades recomendáveis provavelmente vão requerer suplementação:
http://time.com/4547919/this-compound-in-broccoli-can-slow-aging/
https://www.thesun.co.uk/news/2072621/broccoli-cucumber-and-avocado-may-hold-key-to-anti-ageing-claim-scientists/
https://www.yahoo.com/style/totally-normal-dinner-food-might-231002455.html
Citando:
"The mice who were treated with NMN gained less weight, converted food into energy more quickly, and had better blood sugar levels than the animals who were not given the compound.
The reduced risk of age-related diseases led researchers to speculate that consuming foods with NMN could potentially lead to longer life spans for humans. Researchers at Keio University in Tokyo have launched a study on humans by giving the participants supplements of NMN in pill form."

Ingredientes de manteiga de amendoim?
Há manteiga de amendoim e manteiga de amendoim. Algumas não contêm qualquer tipo de ingrediente adicional (sal, açúcar, conservantes) que não o amendoim:
- Resultados da pesquisa "manteiga amendoim":
- O tamanho "normal": https://www.prozis.com/pt/pt/prozis-foods/manteiga-de-amendoim-500-g
- O tamanho "alarve": https://www.prozis.com/pt/pt/prozis-foods/manteiga-de-amendoim-1000-g
- Citando o sítio:
- "O Peanut Butter da Prozis Foods é feito a partir de um único ingrediente, amendoins, para que desfrutes de um creme de barrar natural e delicioso ou então como adição a um batido. Para além de serem uma fonte saudável de proteína de construção muscular e ácidos gordos de grande valor energético, os amendoins também fornecem uma boa quantidade de fibra, vitamina E e magnésio. O magnésio é especialmente importante para indivíduos ativos que pratiquem exercício, uma vez que contribui para o funcionamento normal dos músculos e para uma síntese proteica adequada, para além de reduzir o cansaço e a fadiga. Uma colher desta manteiga de amendoim fornece-te mais proteína e muito menos hidratos de carbono do que a versão normal que podes comprar no supermercado. Faz as contas: em 100 gramas de manteiga de amendoim, 30 gramas são proteína e apenas 7 gramas são hidratos de carbono. Esta proporção de nutrientes, combinada com a composição geral de nutrientes e uma fórmula sem adição de sal, óleos hidrogenados, adoçantes ou aromatizantes artificiais, fazem do Peanut Butter da Prozis Foods uma excelente escolha para aqueles que exigem a melhor nutrição.
- Totalmente natural, sem aromatizantes artificiais nem adoçantes; Excelente potenciador de energia e fonte de proteína; Rico em antioxidantes, magnésio e ácidos gordos saudáveis; Mais proteína e menos hidratos de carbono do que a manteiga de amendoim tradicional; Sem adição de sal e gorduras trans; Adequado a dietas Vegan, Kosher e Halal."
- Mais exemplos:
- De salientar que a manteiga de amendoim não tem muitos ingredientes mas tem outra "coisa": muitas calorias (relevante para quem esteja a tentar controlar o peso).
- Há também a manteiga de amêndoa com 1 ingrediente. Conseguem adivinhar qual?
Fica a informação. FFR.

Ai os Glifosatos - reloaded
A novela continua... Agora a OMS diz a um departamento para não publicar informações até que alguém (quem?) as analise:
http://www.dailymail.co.uk/wires/reuters/article-3871834/WHO-cancer-agency-asked-experts-withhold-weedkiller-documents.html
Citando:
"Pressure has been growing on the experts who worked on IARC's glyphosate review in part because other regulators, including in the United States, Europe, Canada, Japan and New Zealand, say the weedkiller is unlikely to pose a cancer risk to humans.
The conflicting scientific assessments have delayed a decision on whether glyphosate should be relicensed for sale in Europe, and prompted senior U.S. lawmakers to question whether IARC should receive funding from U.S. taxpayers.
IARC defends its methods as scientifically sound and says its monographs - the name it gives to its classifications of carcinogens - are "widely respected for their scientific rigor, standardized and transparent process and ... freedom from conflicts of interest"."

Carência de Vitamina D em Portugal - Estudo

10 Slimming/Anti-inflamatory Foods to Eat If You Sit All Day | TIME
Mais uma daquelas listas, algo questionáveis. De qualquer forma há estudos a indicar que estar sentado muito tempo tem efeitos inflamatórios e estes alimentos / ingredientes suprimem a inflamação (o foco não é emagrecimento como o título indicia mas supressão da inflamação):
10 Slimming Foods to Eat If You Sit All Day | TIME
Citando:
"Science backs this up: Prolonged sitting has been linked to everything from increased hunger and inflammation (which both lead to obesity and belly fat) to high blood pressure and high blood sugar. If you’ve ever heard the phrase “sitting is the new smoking,” now you know where it stems from. But the damage doesn’t stop there. In addition to these preventable diseases, spending too much time on your behind can also result in tight hip flexors, back pain, weak glutes, and rounded, sore shoulders which are all things that can decrease the effectiveness of your workout or lead to a disabling injury, says Piya Tony Vacharasanee, NASM, ACSM, of Body Space Fitness in New York City. All that from an innocent-looking swivel chair.
(...)
But tweaking your diet may also help diminish some of the health risks associated with sitting. A number of nutrients have been shown to fight inflammation by “turning off” inflammatory genes. Add these recommended foods that follow into your diet to help ease some of the damage of your 9-to-5 and you’ll be on your way to a leaner, healthier you."

Resveratrol ajuda a corrigir níveis hormonais de mulheres (PCOS)

"RESVERATROL, a polyphenol which occurs naturally in red wine, grapes, nuts and chocolate, could correct a hormonal imbalance in women with Polycystic Ovary Syndrome (PCOS), a condition which can cause infertility in women of childbearing age.
Researchers at the University of California, San Diego, have demonstrated that a polyphenol called resveratrol, which is found in red wine, peanuts, blackberries and chocolate, was able to correct hormone levels in 30 patients with Polycystic Ovary Syndrome (PCOS)."

Pasta de dentes revolucionária
... Que ao reduzir os problemas na gengiva / placa bacteriana consegue reduzir os efeitos do processo inflamatório (que acaba por afectar o coração) com menos efeitos secundários que as estatinas, a aspirina e outros medicamentos usados:

"His research is estimated to have saved more than a million lives worldwide.
Speaking to the Daily Telegraph, the professor added: ‘This could have policy implications for tens of millions of people alongside statins, aspirin and beta blockers and other agents that help lower cardiovascular disease.
‘The distinguishing thing in my mind about this is that it is a fairly simple thing to do and yet it could have a big impact. And there are no side-effects that we know of.’
(...)
Created in the US, the special toothpaste removes twice as much plaque as rivals.
Levels of inflammation in those using it fell by 29 per cent – only slightly lower than the level of 37 per cent achieved by the use of statins.
Inflammation is measured by the high sensitivity C-reactive protein, a marker for heart attacks and strokes."

Noz-de-areca e cancro
A noz-de-areca ou pinangue (por vezes designada erradamente por noz de betel) é considerada cancerígena sendo mascada em muitos locais da Ásia (e é ingrediente de uma mistura de especiarias, sementes e especiarias - pan masala - tomada depois das refeições para refrescar o hálito e ajudar a digestão - publicitado por Pierce Bosnan, ex-007, na Índia, contra a vontade do Governo Indiano). Resta saber se este ingrediente aparece em pastas de caril, tikka massala e afins - relevante para quem é perdido por comida asiática.

"Muitos mascadores habituais de bétele perdem os dentes já na idade de vinte e cinco anos. Além disso, a Agência Internacional para a Pesquisa do Cancro (IARC - International Agency of Research on Cancer) classifica a noz de bétele como um cancerígeno conhecido. Dosagens altas podem causar diarreia e tonturas. Doses muito altas podem ser mortais. O uso a longo termo pode causar habituação. Em pesquisas efectuadas entre consumidores que tanto usaram o tabaco como a noz de bétele disseram que, entre os dois, acharam mais difícil vencer o hábito de mascar a noz."

Privação do sononpode levar a depressão?
Que a depressão afecta o sono (insónias) já se sabe. E se o contrário também for verdade?
http://thewire.in/73233/lack-sleep-makes-us-depressed-can/
Citando:
"But could things really be the other way around? Could poor sleep be making you depressed? Over the past decade or so it has become increasingly clear that disturbed sleep often comes before an episode of depression, not afterwards, helping to do away with the notion that sleep problems are secondary to other disorders."
(...)
"It was found that participants who had been sleep deprived for approximately 35 hours showed a greater amygdala response when presented with emotionally negative pictures when compared to those who had not been sleep deprived. Interestingly, links with parts of the brain that regulate the amygdala seemed weaker, too – meaning that the participants were perhaps less able to control their emotions. Such findings could help to explain how poor sleep may actually cause difficulties such as depression."

Mutação em gene faz preferir comida mais calórica
http://www.telegraph.co.uk/science/2016/10/04/scientists-discover-fat-craving-gene-after-hosting-all-you-can-e/
Citando:
"Scientists have found a gene mutation which makes fatty foods irresistible, and even causes carriers to reject low-calorie versions of the same meal - even when it looks and tastes identical."
Sobre o gene MC4R:
"British scientists have identified a section of genetic code that makes half the population more vulnerable to obesity, diabetes and heart disease.
Those carrying the sequence are on average 4.4lb (2kg) heavier than those who lack it, with 2cm larger waistline, and a tendency to become resistant to the effects of insulin - which can lead to Type 2 diabetes.
The DNA sequence - carried by 50 per cent of the UK population - is a third more common among people of Indian Asian ancestry than among Europeans, say researchers."

Afinal o treino do cérebro não funciona...
Aparentemente afinal o treino do cérebro não funciona ou melhor, funciona, mas não se encontra provado que certos treinos se reflictam positivamente no campo profissional ou noutra área diferente. Assim se treinarmos o Tetris, ficamos melhor no Tetris mas não esta provado que isso nos ajude profissionalmente ou atrasando o aparecimento de doenças degenerativas (como o Alzheimer).

Pílula contraceptiva ligada a depressão?
... Ou "doorhandle diagnosis" conforme o autor desta notícia suspeita?
http://www.dailymail.co.uk/health/article-3816789/DR-MAX-MIND-DOCTOR-reason-Pill-linked-depression.html
Citando:
"Doorknob revelations can be crucial. A throw-away remark made by a patient as they’re halfway out the door may just be the missing piece of the puzzle; the clue that sounds a klaxon that the patient has a serious physical illness, such as cancer.
However, in my experience, a ‘door-handle diagnosis’ is very often about a patient’s mental health — because, I think, people are too embarrassed or ashamed to make an appointment explicitly to discuss how they are feeling.
Doorhandle diagnosis shows why a really good GP, or nurse, should routinely ask their patient , ever so casually, if everything else is OK."

Ai o [herbicida] Glifosato, outra vez
A FDA está a encontrar Glifosato (presente no Roundup, o sucesso de vendas da Monsanto) em comida de bebé (aveia, trigo):
http://m.huffpost.com/us/entry/12252824
A Monsanto factura 15 mil milhões de USD por ano e cerca de um terço deste valor (5 mil milhões) deriva de produtos contendo glifosatos (recentemente identificados como possível causa de cancro).

A Monsanto factura 15 mil milhões de USD por ano e cerca de um terço deste valor (5 mil milhões) deriva de produtos contendo glifosatos (recentemente identificados como possível causa de cancro). Muitos detalhes no artigo acima, incluindo o link para o PDF da Monsanto que recomenda uma aplicação final pré-colheita. Genial!
O que é a DLB?
É mais um tipo de demência (que pode representar 15% dos casos e que por vezes é mal diagnosticada - como foi para este famoso actor):

"Dementia with Lewy bodies (DLB) is a type of dementia that shares symptoms with both Alzheimer’s disease and Parkinson’s disease.
It may account for 10-15 per cent of all cases of dementia.
DLB can be diagnosed wrongly and is often mistaken for Alzheimer’s disease.
Lewy bodies are the cause of DLB and Parkinson’s disease. They are two of several diseases caused by Lewy bodies that affect the brain and nervous system and get worse over time. These are sometimes called Lewy body disorders.
The way someone is affected by DLB will depend partly on where the Lewy bodies are in the brain:
Lewy bodies at the base of the brain are closely linked to problems with movement (motor symptoms). These are the main feature of Parkinson’s disease.
Lewy bodies in the outer layers of the brain are linked to problems with mental abilities (cognitive symptoms), which is a feature of DLB.
Symptons include problems with mental abilities, such as staring into space for a long time or periods when speech is disorganised; depression; day-to-day memory loss; hallucinations and delusions; movement problems; sleep disturbance; a loss of smell; urinary incontinence.

Saúde mental no Reino Unido
... A degradar-se desde o último inquérito:
http://m.huffpost.com/uk/entry/12262340
Citando:
"The seven years since the last Adult Psychiatric Morbidity Survey has seen the start of a major change in the way our society views mental health. A notable shift in public attitudes towards mental health is underway, and mental health issues are now widely recognised.
Factors such as recession, poverty and unemployment have adversely affected the mental health of the nation, leading to an increase in demand for help and support and at the same time, services are under enormous pressure.
The data paints a stark picture. In some groups of the population it is stabilising, while in other groups it is worsening. Nowhere is it improving. We can now start to see the true scale of an issue which has been stigmatised for centuries and it is deeply worrying for all. "

Álcool como anti-depressivo (auto-medicação)?

Citando:
"Because of the high comorbidity between major depressive disorder and alcoholism there is the widely recognized self-medication hypothesis, suggesting that depressed individuals may turn to drinking as a means to treat their depression," she said in a press release. "We now have biochemical and behavioral data to support that hypothesis."
Raab-Graham cautioned, however, that relying on the intoxicating substance can still pose a threat.
"There's definitely a danger in self-medicating with alcohol," she added. "There's a very fine line between it being helpful and harmful, and at some point during repeated use self-medication turns into addiction."
