Óleo de côco, sim ou não?

Citando:
"A. Coconut oil’s image has gotten a makeover in recent years, and many natural food stores stock the product. But despite “a lot of hype about it,” said Dr. Alice H. Lichtenstein, a Tufts University professor of nutrition science and policy who is vice chair of the federal government’s dietary guidelines advisory committee, “there’s virtually no data to support the hype.”

Coconut oil is high in saturated fatty acids, and saturated fat has been linked to high cholesterol levels and heart disease. Though critics have recently raised questions about the scientific evidence for the link, longstanding dietary guidelines urge Americans to reduce saturated fat intake to less than 10 percent of daily calories, or about 20 grams for a 2,000-calorie-a-day diet."

(...)

"Refined, bleached and deodorized, or R.B.D., coconut oil, which has been treated with solvents and subjected to intense heat, raises cholesterol so reliably that scientists have used it as a control when running experiments on different fats. The harsh processing may destroy some of the good essential fatty acids and antioxidants, such as lauric acid, a medium chain fatty acid believed to raise good H.D.L. cholesterol.

“If you’re going to use coconut oil, make sure you get virgin oil,” Dr. Brenna said. “And, of course, everything in moderation.”"

Mais um episódio da novela das Estatinas

Leiam o artigo mas leiam também os comentários (artigo de um médico a defender o uso de estatinas):
https://www.publico.pt/2017/08/13/ciencia/noticia/colesterol-e-estatinas-porque-ter-medo-da-verdade-1782065

A realidade dos factos (no meu caso) é que perante a ameaça da minha Médica de Família ("estes níveis de colesterol ou baixam ou começa a tomar estatinas, veja lá o que é que come", algo assim), eu comecei a fazer exercício (moderado) e os parâmetros alteram-se radicalmente (tornando desnecessária a medicação "milagrosa"). Que médicos recomendam o exercício em vez de nos dar o comprimidinho? Muitos poucos.

Ai as estatinas (e os ataques cardíacos - NOT)!

Batalhando e voltando a dar, as estatinas tomadas para o colesterol e, por vezes como prevenção de ataques cardíacos afinal parecem não fazer grande coisa (de acordo com este estudo):
http://www.express.co.uk/life-style/health/808096/heart-attack-symptoms-statins

Citação:
"Statins, medication which helps to reduce cholesterol, are being increasingly prescribed to older patients to prevent premature death.

However, now experts have said the is a lack of evidence this actually benefits the patients.

A new study published today has revealed the drugs might not extend lifespan in adults with healthy hearts.

Researchers based in New York City have analysed data from more than 2,500 adults who participated in a previous trial around hypertension and treatment to prevent heart attacks, which finished in 2002."

Reduzir colesterol e prevenir ataques cardíacos?

Novo medicamento reduz em muito os níveis de colesterol e ajuda doentes cardíacos (novo estudo que custou mil milhões):
https://mobile.nytimes.com/2017/03/17/health/cholesterol-drugs-repatha-amgen-pcsk9-inhibitors.html?_r=0

Citando:
"The drug, Repatha, is called a PCSK9 inhibitor and can make cholesterol tumble to levels almost never seen naturally in adults, or even in people taking cholesterol-lowering statins. The Amgen drug and a similar one, sold by Sanofi and Regeneron, were approved by the Food and Drug Administration in 2015 with the hope — and expectation — that they would lower the risk of heart attacks and strokes, and not just reduce levels of LDL cholesterol, the dangerous kind.

That hope has now been realized for the Amgen drug."

Gene associado a desordens ao nível do colesterol

... que se não forem tratadas (com estatinas desde cedo) podem levar a morte prematura:
http://www.heraldscotland.com/news/15106022.Gene_puts_thousands_at_risk_of_early_heart_attack_death/

Citando:
"The British Heart Foundation is calling for improved screening to pinpoint those affected by the inherited condition, known as familial hypercholesterolaemia (FH), after new estimates indicated the genetic defect is more common in Scottish children than type one diabetes and is likely to affect around 21,000 people in Scotland."
(...)
"FH causes abnormally high levels of cholesterol in a person’s blood, meaning that otherwise healthy individuals are at a much greater risk of having a heart attack at a young age.

Without treatment, people with FH can die prematurely in their 20s, 30s or 40s. Each child of a parent who has FH has a 50 per cent chance of inheriting the condition.

Early treatment with statins can bring a carrier’s life expectancy back to that of someone without the condition. However, the BHF warns that people are needlessly dying because most people are not diagnosed and treated for the condition, despite one of the faulty genes responsible for the majority of FH cases first being discovered 30 years ago."

Alternativa às estatinas aprovada no RU (colesterol)

"Patients that have high levels of LDL cholesterol, an inherited form of high cholesterol levels and those who are statin intolerant will benefit.
Despite the widespread use of statins and other lipid-lowering therapies to reduce raised cholesterol levels, some people in the UK remain at significant risk of having a cardiovascular event and are unable to lower their cholesterol to levels indicated within national guidelines.
Alirocumab belongs to the most recent cholesterol-lowering class of treatments called PCSK9 inhibitors.
PCSK9 is a protein that plays an important role in managing ‘bad’ cholesterol by regulating the number of receptors for ‘bad’ cholesterol on the liver’s surface."

Estudo: Walnuts and Healthy Ageing (WAHA) study

Citando:

"Just one-and-a-half ounces of the nuts, high in polyunsaturated fats, can boost friendly bacteria in the gut which reduce inflammation and cholesterol - both of which contribute to heart disease.

They also reduce hungry and increased feeling full.

Every 28 grammes (1oz) of walnuts contains 13 grammes of polyunsaturated fat and they are the only nut with high levels of plant-based omega-3 fatty acid with 2.5 grammes per ounce serving."

O mito do colesterol - Manuel Pinto Coelho | Público

Este não é um artigo sobre colesterol: É um artigo sobre a Indústria Farmacêutica. 

(...) Daí a importância do seu biomarcador – a PCR (Proteína C Reativa) – estar abaixo de 0,5. Quem o tem abaixo deste valor pode comer gorduras à vontade.

Sendo assim, se o aumento da taxa de colesterol é um meio que o organismo encontra para se proteger, então baixar a sua taxa com medicamentos, estatinas ou quaisquer outros, não parece boa ideia. (...)
