The standard explanation of how Heart disease and stroke are caused is pretty well understood. In short the idea is that high levels of the wrong kind of cholesterol
I’m not covering the standard stuff we all know about. I’m looking at different angles. The stuff that rarely gets covered. I want to discuss the value of these insights.
I was fascinated to find out that the standard explanation for cholesterol causing heart attacks is not the only explanation. In fact there are some serious challenges to this explanation. The more you start challenging it the more you may find yourself doubting that it’s the only or main cause of heart disease at all
I really started to doubt the explanation when I discovered A different view on cholesterol:I found it a fascinating read and, in my view, really blows the traditional view out of the water. I still want to double check some of the claims made but I found it a very informative article. Not only does it explain clearly what chemicals and structures are like specific cholesterol and Ldls it explains exactly why they can’t be causing coronary heard disease (CHD) or heart attacks.
So should we ignore the cholesterol hypothesis completely? I don’t think so. There’s still plenty of evidence for it. It’s simply an area of health where we want fact but the explanations are not rock solid.
To take this analysis further let’s consider Saturated fat. Why all the fuss?: This analysis goes right to the heart of this topic. It’s a discussion of saturated fat and its impact on health but also the lack of quality in reporting science. I feel fats are vey much misunderstood and the whole topic is trivialised. I wish it were treated with more care and respect. Then we could all learn how to maximise our health
To that end I looked a little deeper at one of the supposedly man-made fats known as trans-fats. and asked the question why are trans fats so bad?. By only using wikipedia I accept I didn’t do a totally thorough analysis. For an initial investigation though it explains why trans fats could be dangerous.
In my view all these explanations assume that we are essentially weak. That nature has no answer to these problems and that humans must manufacture their own solution. This means medical or nutritional interventions which cost money.
I don’t accept this. On a daily basis the human body overcomes many difficulties. There’s plenty of evidence that a well maintained body doesn’t suffer from these maladies and doesn’t require interventions. So my question is:
what natural, possibly lifestyle, factors should we be considering that may be preventing our bodies from repairing this damage in the first place?
We saw that in the case of Diabetes our bodies forget how to handle sugars but we can remind them. So is there a similar story with heart attack and strokes and arterial disease that causes them?
You’ll find that I keep coming back to this topic. That our bodies are inherently strong and well designed to thrive. Yet without a manual to guide us, our lifestyles often cause as many problems as they solve. This isn’t a bad thing. Just something that we can address once we understand our bodies relationship to our lifestyle.
Lack of repair
There are a few explanations I have considered. My favourite is the idea that cholesterol is the good guy not the bad guy. It is part of the healing process and therefore turns up in numbers at any site of damage in the body.
The real cause is in effective healing. Healing needs rest and relaxation. Two things western lifestyles don’t encourage. Relaxation means low adrenalin. Your body won’t heal when adrenalin flows through your body because it is getting ready to run. Proper rest needs relaxation and healing needs deep sleep. Something you won’t get if you don’t relax properly.
So your body is continually in a state of repair. It never actually finishes the job. On top of that the healing processes themselves aren’t very efficient. They’re not the highly effective and quick processes they should be.
Phew. That’s actually quite a long summary isn’t it. It’s also a lot to expand on. So I’ve looked long and hard for evidence for and against this. Unfortunately studies just don’t generally track these kinds of factors. So it has to remain theory for now.
It is important to realise an often overlooked fact. Cholesterol is a building block of the body. Involved in both repair of cells and growth. From this angle it’s no surprise cholesterol is at the site of artery damage as part of the bodies recovery effort. Then consider that repair and growth require good sleep. Western lifestyles generally don’t value sleep. They value entertainment and pushing yourself to the limit.
So I began to ask the question could lack of sleep increase your risk of heart problems?. Frustratingly it’s very hard to find any evidence either way. Mainly because sleep just isn’t a factor monitored in most studies let alone heart disease and stroke.
Protecting our DNA
Heart disease is unlikely to have just one cause. It’s far more likely to have multiple causes. Each case will represent one or more of these causes collectively. This means it’s multi-factorial. So I also have another favourite theory of how heart disease could come about.
As silly as it sounds it’s possible that our immune system could be involved. We know our immune system is constantly protecting us from foreign invaders in the form of viruses and bacteria. What’s often not considered is the impact of an overworked or ineffective immune system against determined foreign invaders waiting for the chance to get a foot hold in our cells..
The logic here is that viruses work by infecting a cell and taking it over. This means they get a cell to do their bidding. So instead of working to help our body, they now help the virus. Yet they still generally look and act like normal cells within our body. So they’re kind of like a spy. What makes a cancer cell is that it will begin dividing to make more copies of itself. The problem for the body is that most cells die. It’s a natural protective mechanism. Cancer cells don’t
An ineffective immune system allows infection
But how could cancer cells and viruses cause heart disease, or in this case heart attacks? Well, my theory, and it is only a theory, is that an over worked, tired or ineffective immune system would allow viruses and bacteria to take hold in small amounts throughout our bodies. These would then multiply and grow.
Eventually causing problems, blockages, cell ruptures or other problems. Cholesterol is involved simply because it is part of the cell repair process. Just like construction workers end up at the scene after big earthquakes, floods and other types of damage. So cholesterol turns up when the body is damaged because it is needed to make repairs.
- infection leads to damage throughout the body
- body tries to repair using cholesterol
- cholesterol build up occurs.
The question here is what causes an ineffective immune system?
Heart disease has a lot do to with the body not working as it should leading to nutrients like calcium turning up in the wrong place. The following fascinating talk on heart disease and the build up of bone in arteries explains some of the detail around this phenomenon which reduces the elasticity of blood vessels, reducing their ability to adapt to demand and making them more brittle.
The point of this post was to explain other reasons that can explain the cause of heart disease. Not to replace existing wisdom but to complement it. Most illnesses this wide spread and complex have various causes. Each adding to the problem.
These explanations make it easier, not harder, for me to understand both where heart disease comes from and how to tackle it. Each explanation has a related solution or treatment which I will detail later. For now I hope this helps you as much as it has helped me. I see CHD differently after this. As something I can understand and prevent. That gives me a lot of hope.

Specific articles: Heart Disease and Activity
At this point I simply have a big long list of articles I have collected over the years. Each article has informed my view in some way. I’ve been on a path of discovery not just on how activity can help heart disease and how to actually make the activity easy to do.
I also want a more holistic approach. Understand more about food and drink so I can understand a fun lifestyle that works and also adapts to the person following it. That is why things have taken so long. This is a long quest full of confusing speculation and little fact. I’ve tried and explored so much that I’m now confident enough to share.
I apologise for the clutter. For now it’s just wonderful to finally have everything all in one place that is publicly accessible.
I can now begin to organise it properly and present it better.[Learn more about]
