"But high blood pressure can often be prevented or reduced by eating more potassium.

Potassium helps to balance out the negative effects of salt and lower your blood pressure, according to Blood Pressure UK.

It advises: “To reap the benefits of more potassium in your life, try to eat at least five portions of fruit and vegetables every day. (A portion is about the same size as your closed fist.)

“Not only will this help to lower your blood pressure, it will also help you to avoid certain cancers, bowel problems and even heart attacks or strokes.”"
(...)
"Good sources of potassium include potatoes, sweet potatoes, bananas, tomato sauce (without added salt or sugar), orange juice, tuna (fresh, frozen or tinned, but avoid tuna packed in brine), yoghurt and fat-free milk.

But it warns: “If you have kidney disease, or are taking certain blood pressure medication, a large increase in potassium cold be harmful.

“In this case, avoid taking potassium supplements and check with your doctor before drastically increasing your potassium intake.”"

Batatas e tensão alta?

"igher consumption of potatoes (whether fried, boiled, baked, or mashed) is associated with an increased risk of high blood pressure, according to a study published in the British Medical Journal.

The research suggests that replacing one daily serving of potatoes with other, non-starchy vegetables could reduce the risk of developing hypertension.

The researchers, from Harvard Medical School in the US, followed over 187,000 men and women from three large US studies for more than 20 years. They measured dietary intake, including frequency of potato consumption, with a questionnaire. Blood pressure was measured by a health professional."

Sal e hipertensão nem por isso?

Estudo questiona que sal provoca tensão alta:

Citando:
"Researchers followed more than 2,600 men and women over a period of 16 years
They discovered that consuming less salt wasn't linked to lower blood pressure
New findings call into question salt limits recommended by dietary guidelines

Cutting salt from your diet may not be the answer to lower blood pressure, a study has found.

The NHS advice is for adults to eat no more than six grams of salt a day – the equivalent of 2.4 grams of sodium.

But a study by Boston University found people consuming less salt than this actually had higher blood pressure, prompting a call for the guidance to be changed.

Researchers say the advice to eat less salt is too simple and ignores the fact that salt can raise hormone levels in the body which regulate and keep blood pressure low.
(...)
While many people with heart disease who cut salty, processed food out of their diet do see their blood pressure fall, these tend to be 'salt-sensitive' people, which may be why they have bad hearts to begin with.

Salt can cut blood pressure in some people, but the experts say potassium, found in bananas and potatoes, can help tip the balance too, along with magnesium and calcium. 

Levels of these could explain why some people who consumed more than six grams of salt had lower blood pressure."

Definição de alimento com baixo teor de sódio e tipos de sal

Um grama de sal grosso (sal de cozinha) contém cerca de 400mg de sódio. Outros tipos de sal contêm teores de sal diferentes (ver abaixo).

Um alimento​ com baixo teor de sódio o que é?
http://pt.m.wikihow.com/Ter-uma-Dieta-com-Baixo-Teor-de-S%C3%B3dio

Citando:
""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):

E os outros tipos de sal (para além do cloreto de sódio) que quantidade de sódio contêm?

"1 g de flor de sal = 450 mg de sódio

1 g de sal marinho = 420 mg de sódio

1 g de sal de cozinha / sal refinado = 400 mg de sódio

1 g de sal grosso = 400 mg de sódio

1g de sal defumado = 395 mg de sódio

1 g de sal havaiano = 390 mg de sódio

1 g de sal negro = 380 mg de sódio

1 g de sal rosa do Himalaia = 230 mg de sódio

1 g de sal light = 197 mg de sódio"

Tratamento 4 em 1 para tensão alta com elevada taxa de sucesso e reduzidos efeitos secundários

Uma combinação de 4 medicamentos já conhecidos em doses reduzidas teve resultados muito positivos e sem efeitos secundários dignos de registo (muito importante para tratamentos a longo prazo com este tipo de medicação):

http://m.indiatoday.in/story/now-four-in-one-pill-to-treat-high-blood-pressure/1/879831.html

Citando:
"Over four weeks 18 patients in Sydney were either given a quadpill - a single capsule containing four of the most commonly used blood pressure-lowering drugs each at a quarter dose - or a placebo.

This was then repeated for a further four weeks with the patients swapping their course of treatment.

Blood pressure levels were measured hourly over a 24 hour period at the end of each treatment, allowing researchers to significantly reduce the amount of patients normally required in a clinical trial.

As many as 100 per cent of patients on trial saw their blood levels drop below 140 over 90. Just 33 per cent of patients on the placebo achieved this rate.

None of the patients experienced side effects commonly associated with hypertension lowering drugs, which can vary from swollen ankles to kidney abnormalities depending on the type of class of the drug.

"What makes these results even more exciting is that these four blood pressure medications are already in use. We are increasingly finding there are opportunities to treat many commons diseases hiding in plain sight. This ultimately means we will be able to deliver life changing medications much more quickly, and more affordably," "

Batatas e a hipertensão?

Citando:
"Research claims that eating potatoes four times a week could be harmful and contribute to the condition that causes strokes and heart attacks, Britain’s biggest killers.
The study, reported in the BMJ, is the first to identify potatoes as a key source of hypertension, better known as high blood pressure. [However,] potatoes make a useful contribution to nutrient intakes such as fibre and vitamin C"

Snoozing in the daytime increases the risk of hypertension | DailyTimes

Estudo parece encontrar relação entre as sonecas e a hipertensão?

Citando:

"(...) But it seems power naps might be bad for us. Those, who steal forty winks in the day are more likely to suffer from high blood pressure, according to research.
The Mayo Clinic in Minnesota, pooled data from nine studies with 112,267 participants. They found those, who took a snooze in the middle of the day were between 13 and 19 percent more likely to have hypertension.
But, when the researchers looked at the association between night-time napping in those who work night shifts, there was not the same link. One study found shift workers, who napped at night actually had a 21 percent reduced risk.
The clinic’s Dr Wisit Cheungpasitporn said, “More research is needed to better understand if the duration of midday sleep, or if diet, exercise, or an underlying medical condition, might be impacting risk.”"
