World Heart Federation President: Fat Is Protective, Carbs are Harmful!

Get ready for action, with this new attention-grabbing talk by the president of the World Heart Federation, Professor Salim Yusuf. Here are just a few of the controversial, but likely correct, quotes:

  • “Above 40% carb we see a steep increase in CHD risk. Fats are protective.”
  • “Contrary to common belief the current recommendation to reduce saturated fat has no scientific basis.” (at 20:20)
  • “You must have heard of the book Big Fat Surprise by Nina Teicholz. She shook up the nutrition world. But she got it right.” (at 20:33)

Yusuf also gets into the mistaken war on salt, where a moderate amount of sodium (3-5 grams per day) may be optimal.

It’s an excellent talk, if you can stand the slight over-reliance on observational data at some points (it normally does not prove cause and effect). Still, highly recommended!

The Salt Guidelines Are Too Restrictive, Say Experts

Traditional glass salt cellar

Is it really necessary to lower your salt intake as much as the current guidelines advise, in order to lower your blood pressure? According to a new expert paper, the guidelines are way too restrictive and not based on enough evidence.

Cardio Brief: International Experts Call Salt Guidelines Far Too Restrictive

I agree, and especially enjoyed this paragraph:

The new paper also emphasized the potential dangers of lowering sodium too much, as in the WHO and AHA guidelines. “Sodium,” the authors wrote, “is an essential nutrient. This implies that there must be a ‘U’-shaped relationship between dietary sodium intake and cardiovascular events, but there is no consensus of where the minimum risks lies.”

Salt IS an essential nutrient, so why don’t guidelines also mention the minimum intake for optimal health and wellbeing? Studies show that too little salt could even be dangerous.

Salt restriction is usually mainly thought of as a means to control blood pressure, even though the effect is usually modest. Are there other ways than salt restriction to control your blood pressure? Sure – like keeping your insulin low. Which of course can be achieved through a low-carb diet.

#1 Low-Carb Fear: Saturated Fat

time-saturated-fat-butter-cover-smWill saturated fat clog my arteries and give me a heart attack? No. This is one of the biggest nutrition myths of the last few decades. Fortunately, during the last several years more and more experts and organizations have realized that natural saturated fats are completely OK and healthy.

Saturated fat is found in real foods that we’ve consumed throughout evolution. It’s natural to eat saturated fats, it’s found in lots of natural foods, even human breast milk is full of it.

During the last ten years or so, many reviews of all available science have come to the conclusion that there’s no connection between saturated fat and heart disease. This fact has also been recognized in many high-quality newspapers, such as TIME. It’s simply been a mistake.

Don’t fear fat. Updated experts don’t.

#2 Low-Carb Fear: Cholesterol

LDL cholesterolDoes a low-carb diet cause high cholesterol?

Low-carb diets tend to improve the cholesterol profile by increasing levels of the “good” HDL cholesterol, and decreasing levels of harmful triglycerides. These are both good changes, associated with improved health.

Regarding the “bad” LDL cholesterol, most people experience no significant changes on low carb. However, some people can lower or (more often) increase LDL levels somewhat. Note that studies show that at least people over 60 years of age tend to live longer with higher LDL levels.

Taken together, studies show that low-carb diets generally improve risk factors for disease, including cholesterol. For a small minority of people however, cholesterol may go up abnormally high on an LCHF diet. In those situations it could be worth adapting the diet to normalize the cholesterol levels.

The bottom line: Low-carb and high-fat diets on average improve the cholesterol profile and reduce most risk factors for disease. The effect of this has been demonstrated in a 2010 study that showed a reduction in atherosclerosis after two years on a low-carb, high-fat diet.

Ivor Cummins Talks Heart Disease and Insulin Resistance

Here’s an interesting talk about heart disease by Ivor Cummins. You can watch the presentation from the Low Carb USA Keto Getaway either above or following the link below.

Ivor Cummins joined up with our camera crew – Simon Victor and Giorgos Chloros – and recorded a number of interviews in Florida during the last few days. The team just returned, after having a great time with Cummins. The footage – shot with our brand new 4K cameras – looks absolutely amazing. We’ll hopefully get some of it online very soon.

Note that the recording above is not a part of the Diet Doctor production. It’s simply recorded with Cummin’s camera, but it’s certainly good enough to watch.

New Meta-Analysis: Meat Intake Does NOT Appear to Increase Risk of Heart Disease

Humans have been eating meat for millions of years, and so we should be well adapted to it. Nevertheless, some people still believe the somewhat absurd theory that eating meat can produce diseases like heart disease.

The flimsy scientific support for this idea is mostly based on selected observational studies (i.e. statistics), that are unable to prove cause and effect. And even these weak studies are highly conflicting. For example it’s been shown that – adding all studies together – people in Asia who eat more meat get significantly less heart disease, a finding clearly incompatible with the theory.

Now the first, to my knowledge, meta-analysis of higher-quality studies (RCTs) has been published. It finds zero evidence for any negative effects of meat on risk factors for heart disease, including cholesterol.

AJCN: Total Red Meat Intake of ≥0.5 Servings/d Does not Negatively Influence Cardiovascular Disease Risk Factors: A Systemically Searched Meta-Analysis of Randomized Controlled Trials

I’m not surprised. Still, this should kill the bizarre idea that humans could get sick from eating real food like meat.

Brink on the juicy steaks. Especially from grass-fed animals, to make the meat good for the climate too.

Study Showing the Safety of Statin Drugs Is “Fundamentally Flawed”


A new article authored by Dr. Aseem Malhotra (among others) says that a Lancet study demonstrating the safety of statin drugs is very flawed.

Decades of misinformation on cholesterol and the gross exaggeration of statin benefits with downplaying of side effects has likely led to the overmedication of millions of people across the world.

Dr. Aseem Malhotra on BBC – We Should Eat a High-Fat Diet

We’ve cut out fat in general, and saturated fat in particular, during the last decades in order to prevent heart disease. That’s clearly been a mistake. We should do the opposite instead says cardiologist Dr. Aseem Malhotra on BBC.

You can watch the full clip above, and hear Dr. Malhotra’s explanation on why lifestyle medicine and a diet rich in fat is the way to go.
