Vitamin of the Week Part Two – Vitamin B3 – Niacin – Link to cholesterol


smorgasbord health

Earlier in the week I posted on Vitamin B3 – Niacin – and included reference to this nutrient’s effect on the balance of unhealthy and healthy cholesterol in our bodies.

Enzymes in the body are unique substances that speed up chemical reactions in the body. They are responsible for producing the energy we need, the breakdown of dietary fats, the production of certain hormones and cholesterol. In addition they are needed for the processing of genetic material (DNA) and the growth and healthy maturing of cells. B3 is essential for the efficiency of many of these enzymes.

One of the areas that B3 is used therapeutically is in the lowering of cholesterol. B3 actually lowers LDL (lousy cholesterol) and raises HDL (healthy cholesterol). In tests, supplemented B3 proved more effective than many of the normal cholesterol lowering drugs

First a little more about Cholesterol.

I respect and manage my cholesterol levels because without it there are certain vital functions in my body that would not happen. I am rather attached to my steroidal hormones including the sterol Vitamin D (thinks it’s a hormone) that keeps me happy in the winter and free of colds and flu and my bones strong by regulating calcium in my blood. Also in the production of cortisol (there when I need it) and DHEA, very important for my bone density now I am in my 60s; as well as helping keeping me young looking and remembering what happened yesterday!

I am also hoping that my cholesterol, which is very important for my eyesight, will prevent me from developing cataracts in my 70s and 80s. Cholesterol will help prevent me from developing dementia and keeping me active until a ripe old age

Cholesterol is not some demon substance that has invaded our bodies and is rampaging out of control through our blood stream, but essential to our fundamental health and wellbeing. There are a number of people who are genetically prone to cholesterol health issues and of course then medication may be the right decision, but it should never be something that is given to all over a certain age. Something that is often suggested for Statins which have known side-effects.

Those who follow a healthy and balanced diet without many industrially produced foods rarely have a cholesterol imbalance.

How can cholesterol cause a problem in the body?

I admit that I do use the term lousy cholesterol for low density lipoprotein– because this is the one form of cholesterol in our body that can get contaminated and cause health problems. Although when talking about cholesterol we refer to high density lipoprotein (healthy cholesterol) and very low density lipoproteins (not usually in substantial amounts) as well, they are all the same molecularly but have different packaging to be transported in the blood stream.

HDL and LDL sub-divide into different types of lipoproteins and at the moment more is still to be discovered about this. It is the LDL that is associated with the plaque that forms in the arteries leading to blockages.

LDL cholesterol does have a role in the body but has much smaller particles than HDL cholesterol and becomes unstable when it is oxidised – this is where the particles react with free radicals, produced through a number of activities including smoking and eating a diet high in white fat as found in industrially manufactured foods, crisps, pastries and cookies that contain high levels of refined sugars.

If the walls of the arteries are damaged in any way, the smaller and denser particles of the oxidised LDL can push their way through that break in the tissue and start clumping together to form the plaque; whilst the larger HDL particles would not gain purchase. This leads to coronary artery disease.

I think it is important to remember that our bodies have been evolving for a very long time – in a hundred thousand years our DNA will only have altered about ten times which means that we are physically very similar to our first ancestors. I have said before that the body does not react to sudden changes very well!

However, in the last 300 years and particularly the last 150 years since the industrial revolution we have thrown some curved balls at our bodies. Industrially produced foods with manufactured artificial ingredients is just one area where our nutritional needs are not being met – one of the others, which is the real demon in our diet, is refined sugars – addictive -available from birth to grave, within hand’s reach in shops, in our own fridges and store cupboards.

Add these to the laboratory constructed (ugly) fats to extend the sell by date on ready meals and other processed foods in our daily diet and it is no wonder our bodies are in melt down with increased health issues that lead to Heart disease, cancers and dementia.

Coming up tomorrow.

We must not cut fats out of our diet – they have an essential role to play in our health and without fats and cholesterol our bodies will be open to infections, poor function in areas such as the brain, heart, reproductive system and our eyesight.

Tomorrow I will post about the various forms of fats that are currently in our diet and which to enjoy and those to avoid.

It is however, important to make sure to include specific nutrients in your diet, including foods rich in Vitamin B3 which has a vital role in balancing the cholesterol in our diet. You can find out more here.

The Cholesterol Myth – Part One – Why your body needs cholesterol.


I often get emails from readers of my books about the basic key indicators that are essential to keep us alive and healthy – These are LDL Cholesterol levels – Blood Pressure and Blood Sugar Levels… So over the next few weeks I will be covering these three in more detail.

I respect and manage my cholesterol levels because without it there are certain vital functions in my body that would not happen. I am rather attached to my steroidal hormones including the sterol Vitamin D (thinks it’s a hormone) that keeps me happy in the winter and free of colds and flu and my bones strong by regulating calcium in my blood and others such as cortisol, there when I need it and DHEA, very important for my bone density now I am in my 60’s as well as helping keeping me young and remembering what happened yesterday.

I was grateful for my progesterone in my younger days that kept my periods more or less regular and for the oestrogens that developed me into the woman I was and remain today. I am also hoping that my cholesterol, which is very important for my eyesight will prevent me from developing cataracts in my 70’s and 80’s. Developing Dementia and keeping me active until a ripe old age.

Sound flippant? A little yes, but not so flippant as the suggestion that everyone over the age of 50, whatever their current cholesterol readings should be given Statins or other cholesterol lowering drugs. My feeling is that the NHS has given up trying to educate its clients into adopting a healthier diet and exercising more and is going with the mass medication option because they say it will prevent cardiovascular disease and dementia down the line. Quite frankly, they are terrified – they have an aging population- who are going to be more likely to develop heart disease, cancer, and dementia simply because the natural process is deterioration. However, without the protection of healthy forms of cholesterol many functions in the body are compromised including brain health and our sex drive.

What is ‘flippantly’ ignored is that cholesterol is not some demon substance that has invaded our bodies and is rampaging out of control through our blood stream, but essential to our fundamental health and wellbeing. There are a number of people who are genetically prone to cholesterol health issues and of course then medication may be the right decision but it should never be something that is given to all.

There are some lifestyle and dietary changes that we can all make to make sure that the cholesterol in our bodies is getting on with its job and not causing us health problems but before I move onto the solutions, I would like to spend a little exploring the reasons for the interactions that are taking place and resulting in clogged arteries.

Although when talking about cholesterol we refer to high density lipoprotein and very low density lipoproteins (not usually in substantial amounts) as well, they are all the same molecularly but have different packaging to be transported in the blood stream.

HDL and LDL sub divide into different types of lipoproteins and at the moment more is still to be discovered about this. The LDL is associated with the plaque that forms in the arteries leading to blockages – the smaller the size of the LDL particles the more you are likely to develop coronary disease than if the particles are larger and less dense. There is a theory that if the walls of the arteries are damaged in any way, the smaller and denser particles of the LDL can push their way through that break in the tissue and start clumping together to form the plaque whilst the larger HDL particles would not gain purchase.

In essence then, whilst the LDL cholesterol does have a role in the body there are strong indications that if there is already weakness in the artery it will attract the smaller particles that will then clump forming the harmful plaque leading to coronary disease. There is another problem with LDL cholesterol which is oxidation – this is where the particles react with free radicals, produced through a number of activities including smoking and eating a diet high in white fat as found in processed foods, crisps, pastries and cookies.

In my next post I am going to focus on what happens when that oxidation of LDL takes place and why the HDL is accepted as the healthier cholesterol. For the rest of the series I will look at some strategies to get the LDL levels down, raise the HDL and make sure that all of us do not end up on Statins without a libido!
