Sacrilege: High Cholesterol Doesn’t Cause Heart Disease, Say Doctors

Plaque unrelated to cholesterol

From The Irish Times:

There is no evidence that high levels of total cholesterol or of “bad” cholesterol cause heart disease, according to a new paper by 17 international physicians based on a review of patient data of almost 1.3 million people.

The authors also say their review shows the use of statins – cholesterol lowering drugs – is “of doubtful benefit” when used as primary prevention of cardiovascular disease.

The authors include Galway-based Prof Sherif Sultan, professor of the International Society for Vascular Surgery; Scottish-based Dr Malcolm Kendrick, author of The Great Cholesterol Con; and Dr David M Diamond, a US-based neuroscientist and cardiovascular disease researcher.

Prof Sultan said millions of people all over the world, including many with no history of heart disease, are taking statins “despite unproven benefits and serious side effects”.

You may need to cut back on alcohol Photo copyright: Steve Parker MD

You may need to cut back on alcohol.

Drugs to control hypertension can save your life. I prescribe them all the time. However, there are also “natural” ways to control high blood pressure. Click the link at bottom for some of the better known methods from Kerri-Ann Jennings, RD. If you’re trying to avoid drugs, you’ll probably need a combination of tricks. And they don’t work for everybody.

Even if you’re already on drugs, you may be able to cut back or stop them if you adopt some of these tips.

From Jennings:

High blood pressure is a dangerous condition that can damage your heart. It affects one in three people in the US and 1 billion people worldwide.

If left uncontrolled, it raises your risk of heart disease and stroke.

But there’s good news. There are a number of things you can do to lower your blood pressure naturally, even without medication.Here are 15 natural ways to combat high blood pressure.

Tina Speaks From the Heart: A friend’s heart attack, a documentary film, and a celebrity death 

“On Saturday evening, I watched the movie WIDOWMAKER and went to bed with a heavy heart thinking of the high incidence of heart attacks among young men in the age group 38 – 50 in my social circle in the past couple of years.  6 of them had heart attacks, 2 survived. (One of them a friend. It was only after the friend got a heart attack that I started observing the trend.) The remaining 4 left behind young widows, little children and old, distraught parents.After some time, I stopped counting. This is the first generation in the history of mankind to lose their adult children not to war, wild animals or plagues, but to chronic diseases. Quite heartbreaking to see parents bury their young children in the prime of their life.I was grateful that my spouse and I started LCHF 4 years ago. He has lost 30 kgs and has some more to lose.

I realise that had we not started and continued to follow LCHF, I would have already become a widow or would become one in the next 10 years. Or I would have probably left him a widower.”

Reinagel Ponders Whether Calcium Supplements Are Safe

 

Death in a bottle?

Death in a bottle?

Monica Reinagel is a smart and media-savvy nutritionist who brought me on board as a blogger at NutritionData many years ago. Click the link below for her surprising conclusion on calcium supplementation.

Monica writes:

“The National Osteoporosis Foundation published a new report this week, insisting that calcium supplements are safe for your heart. Two weeks ago, Johns Hopkins cardiologist Erin Michos published a paper saying the opposite.

She claims that the NOF review (which was funded by a pharmaceutical company that makes calcium supplements) omitted certain studies (such as the ones she included in her own review) that might have changed the conclusion.

These are just the latest two volleys in a five-year-long tennis match between experts on whether you should or shouldn’t take calcium supplements.  And you thought politics was divisive.”

Mediterranean Diet Could Prevent 20,000 Deaths Per Year in Britain

The Telegraph has the details:

“Some 20,000 lives could be saved each year if Britons switched to a Mediterranean diet, according to a new study.

The Medical Research Council (MRC) and Cambridge University followed nearly 24,000 people in the UK for up to 17 years to see how their diet affected the health of their heart.

They discovered that people who followed a diet high in fruits, vegetables, whole grains, nuts, fish and olive oil lowered their risk of cardiovascular disease by up to 16 per cent. The researchers estimate that 12.5 per cent of cardiovascular deaths, such as heart attacks and strokes,  could be prevented if everyone switched to the Mediterranean diet. There are around 160,000 heart deaths each year so 20,000 deaths could be avoided just by eating more healthy foods.”

I’ve been a proponent of the Mediterranean diet for over a decade. I’m not alone.

High-Carb Diet Linked to Cardiovascular Disease

These cows may give you cancer

Carcinogenic cows?

The idea that heart attacks and other cardiovascular diseases are caused by dietary saturated fats is losing credibility. I lost faith in that theory in 2009.

Instead, cardiovascular disease is now linked to high consumption of carbohydrates, particularly those carbs that are rapidly absorbed and turned into blood sugar.

Unfortunately, the diet that reduces risk of cardiovascular disease may increase your risk of cancer. Keep reading.

If you’re a nutrition science nerd, here’s a pertinent report from researchers at Masaryk University in the Czech Republic:

“The results of our study show that high-glycaemic carbohydrates or a high overall proportion of carbohydrates in the diet are the key ecological correlates of cardiovascular disease (CVD) risk. These findings strikingly contradict the traditional ‘saturated fat hypothesis’, but in reality, they are compatible with the evidence accumulated from observational studies that points to both high glycaemic index and high glycaemic load (the amount of consumed carbohydrates × their glycaemic index) as important triggers of CVDs. The highest glycaemic indices (GI) out of all basic food sources can be found in potatoes and cereal products, which also have one of the highest food insulin indices (FII) that betray their ability to increase insulin levels.The role of the high glycaemic index/load can be explained by the hypothesis linking CVD risk to inflammation resulting from the excessive spikes of blood glucose (‘post-prandial hyperglycaemia’). Furthermore, multiple clinical trials have demonstrated that when compared with low-carbohydrate diets, a low-fat diet increases plasma triglyceride levels and decreases total cholesterol and HDL-cholesterol, which generally indicates a higher CVD risk. Simultaneously, LDL-cholesterol decreases as well and the number of dense, small LDL particles increases at the expense of less dense, large LDL particles, which also indicates increased CVD risk. These findings are mirrored even in the present study because cereals and carbohydrates in general emerge as the strongest correlates of low cholesterol levels.

In light of these findings, the negative correlation of refined sugar with CVD risk may seem surprising, but the mean daily consumption of refined sugar in Europe is quite low (~84 g/day), when compared with potato and cereal carbohydrates (~235 g/day), and makes up only ~20% of CA energy. Refined sugar is also positively tied to many animal products such as animal fat and total fat and animal protein, and negatively to % PC CARB energy and % CA energy. Therefore, a high consumption of refined sugar is accompanied by a high consumption of animal products and lower intakes of other carbohydrates. Furthermore, the glycaemic index of refined sugar (sucrose) is rather moderate (~65).”

Elsewhere in this long article:

“Current rates of cancer incidence in Europe are namely the exact geographical opposite of CVDs. In sharp contrast to CVDs, cancer correlates with the consumption of animal food (particularly animal fat), alcohol, a high dietary protein quality, high cholesterol levels, high health expenditure, and above average height. These contrasting patterns mirror physiological mechanisms underlying physical growth and the development of cancer and CVDs. The best example of this health paradox is again that of French men, who have the lowest rates of CVD mortality in Europe, but the highest rates of cancer incidence. In other words, cancer and CVDs appear to express two extremes of a fundamental metabolic disbalance that is related to factors such as cholesterol and IGF-1 (insulin-like growth factor).”

I wish these researchers had looked at over death rates associated with various ways of eating. Perhaps that will be in a future paper.

I’d rather die of a heart attack than cancer.

FDA Says Jardiance Can Claim Cardiovascular Death Prevention 

Jardiance is a diabetes drug in the class called SGLT2 inhibitors.

How do they work? Our kidneys filter glucose (sugar) out of our bloodstream, then reabsorb that glucose back into the bloodstream. SGLT2 inhibitors impair that reabsorption process, allowing some glucose to be excreted in our urine. You could call it a diuretic effect. For example, an SGLT 2 inhibitor called dapagliflozin, at a dose of 10 mg/day, causes the urinary loss of 70 grams of glucose daily.

How drugs like this could prevent cardiovascular disease in type 2 diabetics is a mystery to me.

From MPT:

“The diabetes drug empagliflozin (Jardiance) may be marketed for prevention of cardiovascular death in patients with type 2 diabetes and co-existing cardiovascular disease, the FDA said Friday.

It’s the first such claim ever allowed for a diabetes drug.

Empagliflozin, first approved in 2014, is an inhibitor of the sodium-glucose co-transporter 2 (SGLT2) pathway, reducing blood glucose by causing it to be excreted in urine.Its benefit for cardiovascular risk reduction was demonstrated in the so-called EMPA-REG trial, results of which were reported in 2015.”
