Batons de cieiro perigosos?

http://observador.pt/2017/09/27/ha-14-batons-hidratantes-perigosos-no-mercado-alerta-a-deco/

Citando:
"Na compra de um destes batons deve prestar atenção aos ingredientes. Se a lista contempla siglas como MOSH, POSH e MOAH, deve evitar comprá-los. A DECO alerta que “a presença de mais de 10% de hidrocarbonetos MOSH e POSH em produtos que podem ser engolidos, como os hidratantes labiais, é potencialmente perigosa”. Já os MOAH “não devem fazer parte destes cosméticos por se suspeitar de que são cancerígenos”."

Nem todas as bolachas são iguais sabia?

Claro que se sabia. Basta olhar para a composição nutricional:
http://www.sabado.pt/ciencia---saude/detalhe/receita-das-bolachas-de-agua-e-sal-e-maria-pode-ser-alterada

Citando:
"Algumas marcas utilizam o dobro do sal e da gordura que outras que produzem produtos similares. A DGS poderá determinar metas para a reformulação da composição das bolachas.

Uma análise do Instituto Nacional de Saúde Doutor Ricardo Jorge (INSA) revelou que existem marcas de bolachas de água e sal e bolachas Maria – os dois tipos mais consumidos em Portugal – que utilizam o dobro do sal e da gordura que outras marcas que produzem produtos similares.

Os investigadores, que concluíram ser possível produzir os mesmos produtos com uma melhor qualidade nutricional, reforçam que é necessário serem "estabelecidas metas que permitam a reformulação gradual destes alimentos""

Engordar: São os hidratos ou as gorduras?

Hum... Mais estudos:
https://www.publico.pt/2017/09/24/culto/noticia/mas-afinal-o-que-e-pior-sao-os-hidratos-ou-e-a-gordura-1786182

Citando:
"Em todos estes exemplos, o nutriente “engordante” pode ser a gordura, os hidratos, a proteína ou o álcool. Cada indivíduo engorda porque de alguma forma come mais calorias do que as que gasta, mesmo que não se aperceba disso. Um dos padrões mais recorrentes que surgem ultimamente são as semanas limpas e os fins-de-semana desastrosos, isto é, pessoas consciencializadas para se portarem bem durante a semana, mas todas as calorias que vão poupando de 2ª a 6ª, acabam por ser recuperadas ou no jantar de 6ª e sábado, ou no brunch de domingo, ou no casamento/aniversário do fim-de-semana, ou em qualquer roteiro gastronómico que acontece por norma nestes dias.

Concluindo, o que o engorda a si, não é o que engorda o seu colega do lado. O que ambos têm em comum é o excesso calórico. Descubra onde está a sua maior fragilidade alimentar e encontre estratégias para não se expor a ela."

Adoçantes artificiais e risco acrescido de diabetes tipo 2?

http://opiniaoenoticia.com.br/internacional/adocantes-artificiais-podem-aumentar-risco-de-diabetes-tipo-2/

Citando:
"Para isso, alguns dos 27 voluntários receberam o equivalente a 1,5 litros de uma bebida diet por dia, em forma de cápsula de dois adoçantes diferentes: sucralose e acessulfame K. Eles tomavam as cápsulas três vezes por dia durante duas semanas, antes das refeições. Os outros voluntários receberam placebo.

No final de duas semanas, testes mostraram que a resposta do corpo a glicose foi prejudicada. Este estudo apoia o conceito de que adoçantes artificiais podem reduzir o controle do organismo nos níveis de açúcar no sangue."

Ftalatos e retardadores de incêndio (a evitar)

https://www.theguardian.com/science/2016/sep/14/toxic-chemicals-household-dust-health-cancer-infertility

Citando:
"Among them is the flame retardant TDCIPP that is known to be cancer-causing and is frequently found in furniture foam, baby products and carpet padding, as is TPHP, another flame retardant in the top 10 list that can affect the reproductive and nervous systems.

“They are just a bunch of letters – a lot of people might not recognise what those chemicals are, or what they mean, but they are really a number of bad actor chemicals,” said Singla.

Other toxic substances found in almost all of the dust samples include chemicals known as phthalates that are often found in vinyl flooring, food packaging, personal care products and have been linked to developmental problems in babies, hormone disruption, and are also thought to affect the reproductive system."

"Worldwide, people are living longer. But while overall deaths from infectious diseases and preterm birth are decreasing, deaths from heart disease, conflict and terrorism are on the rise, according to a new report.

The report, called the Global Burden of Disease study, examines the state of the world's health by estimating average life expectancy as well as the number of deaths, illnesses and injuries from more than 300 causes."

O "drama" das esponjas da louça

Aparentemente mesmo fervendo não se resolve completamente o problema. A solução proposta é trocar todas as semanas:
http://www.techtimes.com/articles/212267/20170804/kitchen-sponges-are-host-to-millions-of-bacteria.htm

Citando:
""Sanitation by boiling or microwave treatment has been shown to significantly reduce the bacterial load of kitchen sponges and can, therefore, be regarded as a reasonable hygiene measure. However, our data showed that regularly sanitized sponges (as indicated by their users) did not contain less bacteria than uncleaned ones," the researcher reveal.

Not only did some of the bacteria survive the sanitation process, the researchers found that those "sanitation resistant" strains were able to quickly infest the sponge again and could even increase the number of disease-causing bacteria.

The researchers admit that further analyses are needed to substantiate their findings, but they still advise against DIY sanitation of kitchen sponges because it may actually do more harm than good. Their short-term advice is to simply replace kitchen sponges on a regular, weekly basis."

Enxaquecas e bactérias da boca?

http://www.techtimes.com/articles/182905/20161019/your-mouth-bacteria-may-be-what-s-causing-your-migraine.htm

Citando:
"The results of the study suggest a potential link between bacterial nitrate, nitrite, nitric oxide and migraines, because of the higher abundance in migraineurs compared to the people who do not suffer from severe headaches. Although this research opens an horizon for a potentially relevant discovery in treating headaches, further scientific approaches will be necessary to confirm or infirm the large-scale validity of these findings.

Migraine is an inflammation, caused by a change in the brain stem when affected by the trigeminal nerve. Neuropeptides are released as a result to this process, which then travel to meninges or to the outer covering of the brain, causing the migraines."

Os riscos do sedentarismo (mesmo para quem vai ao ginásio)?

Citando:
""Even if you're a gymgoer and think you're safe on account of your excellent effort, you are not," said James Levine, from Mayo Clinic. "No one gets away from this stuff. ... Excess sitting, this study seems to suggest, is a death sentence."

Take A Movement Break Every 30 Minutes

Those who kept their sitting bouts to less than half an hour had the lowest odds for premature death. The researchers said that this means that for those whose job or lifestyle requires them to sit for extended periods of time, taking a movement break every 30 minutes may help reduce their death risk."

Citando:
""This microneedle-based patch can effectively deliver browning agents to the subcutaneous adipocytes in a sustained manner and switch on the "browning" at the targeted region. It is demonstrated that this patch reduces treated fat pad size, increases whole body energy expenditure, and improves type-2 diabetes in vivo in a diet-induced obesity mouse model," Li Qiang, from Columbia University Medical Center, and colleagues wrote in their study, which was published in ACS Nano on Sept. 15."

Batatas fritas perigosas para diabéticos?

Parece que sim. Se a informação nutricional estiver errada, o cálculo de insulina a tomar é mal feito:
http://www.dn.pt/sociedade/interior/batatas-fritas-perigosas-para-diabeticos-tiradas-do-mercado-8774705.html

Citando:
"O caso foi tornado público na edição desta sexta-feira do DN e surpreendeu a ASAE, que, como adiantou fonte desta entidade, não tinha recebido nenhuma denúncia sobre a venda de batatas fritas daquela marca com um erro tipográfico que fez que diabéticos calculassem as doses de insulina que necessitavam de forma errada, pois faziam as contas a 12 gramas de hidratos por cada 100 de batatas, quando o valor real é de 72 gramas de hidratos."

Homens altos mais propensos a cancro da próstata agressivo

https://www.theguardian.com/society/2017/jul/13/tall-men-at-bigger-risk-of-aggressive-prostate-cancer-study-suggests

Citando:
"Tall men are at greater risk of contracting aggressive prostate cancer and of dying from the disease, the findings of a large study suggest.

British scientists found that every 10cm increment in height increased the chance of developing high-grade prostate cancer by 21% and the risk of death from the disease by 17%. They also found that obesity raised the risk of aggressive prostate cancer."

Produtos limpeza (lixívia) associados a doenças dos pulmões

Doença pulmonar obstructiva crónica e produtos de limpeza (uma vez por semana; specific cleaning chemicals known as quaternary ammonium compounds - quats):
https://www.theguardian.com/uk-news/2017/sep/11/regularly-using-bleach-linked-to-higher-risk-of-fatal-lung-disease

Citando:
"Regular use of bleach and other common disinfectants has been linked to a higher risk of developing fatal lung disease, researchers have found.

The use of disinfectants is linked to a higher risk of developing chronic obstructive pulmonary disease (COPD), according to research looking at incidence of the disease in more than 55,000 nurses in the US.

The 30-year study by Harvard University and the French National Institute of Health and Medical Research (Inserm) found that those who used the products just once a week had as high as a 32% increased chance of developing the condition."

Futuro: Biópsias para detecção de tecido canceroso em "caneta"

MasSpec Pen:

http://stm.sciencemag.org/content/9/406/eaan3968

Citando:
"Although a surgeon’s goal is to remove cancer in its entirety during excision surgery, achieving negative margins (absence of cancer cells at the outer edge of the excised tumor specimen) can be challenging. To facilitate intraoperative diagnosis, Zhang et al.developed a handheld pen-like device that rapidly identifies the molecular profile of tissues using a small volume water droplet and mass spectrometry analysis. After 3 s of gentle physical contact with a tissue surface, the water droplet is transported to a mass spectrometer, which characterizes diagnostic proteins, lipids, and metabolites. The pen could be used to rapidly distinguish tumor from healthy tissue during surgery in mice, without requiring specific labeling or imaging and without evidence of tissue destruction."
(...)
"Our results provide evidence that the MasSpec Pen could potentially be used as a clinical and intraoperative technology for ex vivo and in vivo cancer diagnosis."
