""Procure pela inscrição "baixo teor de sódio". Essa indicação deve significar que o alimento contém 140 miligramas ou menos de sódio por porção. Pode também procurar por alimentos "sem sódio" (menos de 5 miligramas por porção) e "com pouco sódio" (menos de 35 miligramas por porção). Outra opção é buscar por alimentos "sem sal"."
A OMS recomenda que a ingestão diária de sódio seja abaixo dos 2000mg (2g)."

A OMS recomenda consumos abaixo dos 5g de sal / dia (2000 mg de sódio):

Potássio ajuda a controlar a tensão arterial

http://www.dailymail.co.uk/health/article-4386998/How-reverse-high-blood-pressure.html

Citando:
"High blood pressure is most often caused by increased levels of dietary sodium
Known as hypertension, it is believed to affect 1 billion people around the world
But scientists have found potassium balances out the effects of salt in the body
Experts claim that the mineral works in the same way as commonly used drugs"
(...)
"HOW MUCH SHOULD YOU EAT?

A 2004 Institute of Medicine report recommends that adults consume at least 4.7 grams of potassium per day to lower blood pressure. This amount would also blunt the effects of dietary sodium and reduce the risks of kidney stones and bone loss. For example, eating three quarters of a cup of black beans will help you achieve almost 50 per cent of your daily potassium goal.

While to achieve the full amount, you would have to consume 11 bananas. "

Antibióticos e Stress Pós-Traumático?

Em mais uma notícia (aparentemente) improvável, antibióticos parecem poder ajudar em Stress Pós-Traumático (de que muitos militares sofrem):

Hope for troops as antibiotics show they could be 'exciting new treatment' for PTSD

Citando:
"While the UCL researchers acknowledge the nature of traumatic events makes it impractical to start people on antibiotics before they happen, they said the drugs could be used subsequently to lessen the “reconsolidation” of memories in the aftermath.

PTSD is thought to affect around one in three people who suffer a traumatic event, which can range from experience of war, a road accident or being diagnosed with a serious illness.

Between one in 20 and one in 25 UK veterans of the Iraq and Afghanistan wars suffer from PTSD, according to the charity Combat Stress.

While this is similar to the rate in the general population, the complexity of the disorder tends to be far greater in former servicemen and women, and also occurs alongside aggravating problems such as pain or alcohol misuse."

Uso de células indiferenciadas do cordão umbilical

Artigo muito interessante que descreve os diversos usos que estão a ser dados a células indiferenciadas do cordão umbilical (que até há muito pouco tempo eram sempre deitados fora):
http://www.independent.co.uk/news/long_reads/cancer-treatment-umbilical-cord-blood-donation-mosaic-a7651891.html

Citando:
"Cord blood contains what are known as stem cells and progenitor cells, which can give rise to oxygen-carrying red blood cells, infection-fighting white blood cells and clot-forming platelets. 

Transplanted cord blood can be used to treat or cure more than 80 conditions, from leukaemia to sickle-cell disease. Based on current research exploring autism, brain injury, cerebral palsy, type 1 diabetes and cardiovascular disease, among others, the list of potential applications is likely to grow. Emerging strategies are even transforming cord blood left over after birth into a potent potion that might provide lifesaving treatments for victims of a nuclear disaster. 

Stem and progenitor cells are also found in the spongy marrow within some bones and in the blood that circulates around our bodies. But cord blood, once dismissed as medical waste, is particularly rich in these cells. As researchers are discovering, it may carry other significant advantages too.

While a cord blood transplant might save your life, though, going through the process and then starting anew – your survival down to an anonymous baby – is far from easy."

Esquecer os crispies (acrilamida)?

Dir-se-ia que sim: Apesar destas marcas não existirem em PT, o panorama dos crispies no Mac, KFC e afins não deve ser muito diferente:
http://m.huffpost.com/uk/entry/uk_58e26d43e4b0b3918c85402a

Citando:
"Almost one in five crisp varieties contain high levels of a known carcinogen called acrylamide, a new report has revealed.

Acrylamide has the potential to cause cancer in humans and, as such, is considered a public health concern by the European Food Safety Authority (EFSA). 

A review of 92 types of crisps from major UK snack brands and supermarkets found that some crisps - including snacks from Tyrrells, Aldi and Morrisons - exceeded the maximum recommended level of acrylamide."

(...)
"These levels are 2.5-times above the European benchmark, which is 1000 micrograms per kilogram and over 83-times higher than products with the lowest concentration.

Morrisons’ cheese and onion flavoured popped potato snacks came next, containing 2067 micrograms of acrylamide per kilogram, followed by the supermarket’s sea salted crinkle cut potato crisps which contained 1826 micrograms per kilogram."

Viagra venda livre no país mais livre do mundo (depois do Brexit)?

Está a ser proposto que o Viagra seja de venda livre (vendido sem receita médica) no RU:
http://www.mirror.co.uk/news/uk-news/viagra-could-soon-available-over-10113518

Citando:
"Packs of eight tablets of Viagra - also called sildenafil - would be made available, with men told to take no more than one tablet per day.

Viagra, which works by relaxing blood vessels, thereby allowing blood to flow to the penis, works for about eight hours and is designed to be used "on demand".

Erectile dysfunction can be caused by a range of conditions, including psychological problems, but can also be a sign of underlying heart disease, diabetes or high blood pressure."
