Cholesterol - clogging your arteries

While dietary fat has no doubt been stigmatised as the truly evil madman that is ruining our health, cholesterol has been branded as the evil sidekick, almost as equally responsible for destroying our bodies.

We’ve been told for decades to avoid foods with cholesterol, because they are what’s clogging our arteries. No egg yolks, only egg whites! We’ve been told that if we want to be healthy, we need to minimise cholesterol consumption. No butter, just margarine! We’ve been told to switch to grains and minimise meat consumption. Meat has cholesterol, and cholesterol is bad! Meat will kill you!

After all this is what we have heard while growing up. It must be true?

Let’s start with explaining what on earth cholesterol is.

Cholesterol is a waxy, fat like substance which is found in all cells in your body.

There are two types of cholesterol.

HDL which stands for high density lipoprotein, this is also known as the ‘good’ cholesterol as it carries cholesterol from other parts of your body back to your liver, where it gets removed.
And LDL which stands for low density lipoprotein and is known as the ‘bad’ cholesterol, as too much LDL can lead to the build up of plaque in your arteries. Your body needs some cholesterol to help you digest food, make hormones, and generate Vitamin D. These all sound like pretty important things. You’re not wrong. So, to make sure we have enough cholesterol to carry out these functions our liver naturally makes cholesterol (around 1000mg+ of it per day). But what about the cholesterol in the food we eat? Well to be honest, dietary cholesterol or cholesterol in your food isn’t actually absorbed that efficiently and is rapidly excreted. To sum this up, the cholesterol you do eat, has little to do with the cholesterol in our blood stream.

If you have too much LDL cholesterol in your blood, it can combine with other substances to form plaque. Plaque sticks to the walls of your arteries. The build-up of plaque is known as atherosclerosis. It can lead to coronary heart disease, where your coronary arteries become narrow or even blocked.

But it really comes down to two things: lifestyle and diet. Too much high carbs, starches and sugar paired with too little exercise can cause inflammation and oxidation which cause plaque build-up in our arteries.

What can affect my cholesterol levels?

While these steps do not fully remove the risk of heart disease and cholesterol, they can help improve overall heart health and inflammation.

• Diet: Remove processed junk. Aim for high fibre foods, lots of vegetables, healthy fats such as avocado, olive oil, nuts and seeds etc and reduce the amount of salt, sugar and alcohol in your diet.
  Fibre is important as it helps lower LDL, a high quality supplement such as FibreMax is a great option.

• Exercise: A lack of physical activity can lead to weight gain, which can raise your LDL level. Exercise helps strengthen your heart, circulatory system and maintains blood pressure.
• Weight: Being overweight often raises your LDL level, lowers your HDL level, and increase your total cholesterol level.
• Smoking: Cigarette smoking lowers your HDL cholesterol. Since HDL helps to remove LDL from your arteries, if you have less HDL, that can contribute to you having a higher LDL level.
• Age and Gender: As women and men get older, their cholesterol levels rise. Before the age of menopause, women have lower total cholesterol levels than men of the same age. After the age of menopause, women’s LDL levels tend to rise.
• Genetics: Your genes partly determine how much cholesterol your body makes. High cholesterol can run in families. For example, familial hypercholesterolemia (FH) is an inherited form of high blood cholesterol.

• Supplementation:

  

  Omegas are known to help support heart health by reducing heart disease and lowering triglycerides (blood fat).(Omega CoQ10)

Long story short: Dietary cholesterol (cholesterol in your food) is poorly absorbed by our body and rapidly excreted, which means the amount of cholesterol you consume has VERY little to do with the levels of cholesterol in our blood stream!
