Why Do a Blood Test?

Today, more than ever, people are taking an interest in their health and overall well-being. Even more importantly, they’re becoming active participants in self-guided healthcare.

This is a very good thing. After all, your state of health ― both now and in the future ― relies mainly on self-directed care. Let’s face it: Who’s going to look after your health more closely than YOU?

As the result of increasing health awareness, an ever-growing number of people are changing lifestyle habits. They’re taking up exercise ― joining a gym and doing yoga, Zumba, CrossFit, and/or weight-bearing exercise… eating a healthier diet with more fruit and vegetables, and going organic… taking time out to relax and practising de-stressing methods and techniques.

At the same time, far too many people don’t truly understand the core aspect of overall health and well-being ― how it can be achieved or maintained. The crux of the issue is to prevent disease before it has a chance to creep in and get a foothold.

But not knowing how to do it doesn’t mean it can’t be done. There is a way to do this! You can obtain optimal health and keep it

Your Blood Doesn’t Lie!

A blood test is the best way to protect and maintain your health, including prevention of disease. It’s absolutely the most accurate method of self-care being offered today.

Disease is a process that develops over time. As an example, insulin resistance (IR) typically precedes diabetes type 2, but it can continue for at least a decade before true diabetes type 2 develops.

And disease usually spawns more disease. Case in point: Diabetes type 2 is linked to a host of other health issues ― Alzheimer’s disease, breast cancer, hypertension, kidney disease, obesity and more. Insulin resistance increases your risk of heart disease, stroke, and non-alcoholic fatty liver disease.

Yes, it’s scary, but you don’t need to get to this point! Your best protection is to monitor your health by getting regular, periodic blood tests and keeping an eye on your results. And, of course, you need to pay attention to your diet, especially your glucose (sugar) intake.

An Ounce of Prevention…

Think about it: No financial crisis happens overnight. It takes years to occur. So, too, do breakdowns of the body. If you are clever enough to stop for a second, take a step back, look at the early warning signs and then take action before the actual event, you can prevent a financial crisis from ever happening. It’s just the same with your body.

Diabetes or any other chronic disease can take years, even decades, to become apparent. The good thing is, you don’t have to wait to get a diagnosis of disease ― a diagnosis that may well send shockwaves through your system.

Instead, pay attention to those minor initial imbalances ― warning symptoms such as headaches, weight gain, etc. ― that eventually, if not attended, evolve into serious health issues and abnormalities. Keep an eye on your health and follow it.

You can guide and improve your health instead of poor health guiding you! You can stay one step ahead. This is possible.

A blood test is the most independent and reliable factor for predicting your health status. Science has gained a tremendous amount of knowledge about physiologic markers that predict impending illnesses and disease. Blood tests give us the ability to detect and measure substances that indicate disease risk.

Blood tests are, in fact, the only way to discover threats to your health that may lie ahead. This knowledge allows you to take action that can prevent risks from becoming your reality.

Is a Normal Level an Optimal Level?

In one word, NO! As a general rule, most people ignore the results of their blood tests, especially when their doctor informs them they’re normal. But what does the term ‘normal’ actually mean? It simply tells you that you are within the expected ranges of someone your age ― that is, your blood tests are not abnormal, or ‘out of range,’ for your age.

However, this doesn’t mean they are optimal.

Typically, conventional doctors don’t discuss blood test results when they are within the conventional ‘normal’ ranges. It isn’t until blood values hover over to the other side of ‘abnormal’ that you’re likely to be told to change your lifestyle. This usually happens only when disease, a disorder or some other health issue has already had the chance to develop within your body. But at this point, it is already late.

Where to Start…

Your blood tests are important. They are your lifeline. They can tell what’s in store for you and when it is time to make important changes before it is too late ― before your condition becomes irreversible.

It’s equally important that you find and work with a qualified restorative medicine doctor, who is light years ahead of conventional medical practitioners in understanding the importance of blood tests.

The goal of restorative doctors isn’t to achieve so-called ‘normal’ ranges, which are already tilting toward disease. Rather, it’s to return your blood to optimal ranges ― around what they were in your 30s when your hormones were at their best and you functioned at your peak. These are the ranges you had when you were young… the ranges that will protect you.

A restorative doctor has the specialised training to know your blood doesn’t lie, knows the right blood tests to order and how to correctly interpret your test results.

What is more, your restorative medicine doctor will continue to work with you and guide you in making needed changes that will make a profound difference in your health outcomes for years to come.

Telomeres: How to Help Prevent Them from Shortening

In my previous blog, I discussed the importance of telomeres to the ageing process and our bodies. Naturally, telomere length, and their impressive health benefits are now gathering more and more interest… the race is on! How do we preserve telomere length in normal cells, which in turn, sustain healthy cellular youth and functionality?

The Answer? Vitamin Supplementation

Over the last few years, scientists have gathered a tremendous and convincing amount of evidence, demonstrating that one way of supporting telomere health and length is to include a daily regime of certain vitamins in adequate amounts including, B vitamins (including vitamin B12, vitamin B6, and folic acid), vitamin D3, vitamin C, and vitamin E (in particular Gamma-tocotrienol which prevent, and may even reverse telomere shortening), and the vegetable carotenoids, such as lutein and zeaxanthin, high levels of which have been seen to promote significantly longer telomeres.

Fish oils have also demonstrated they can significantly impact telomere length. One study showed that by reducing blood levels of omega-6 fats, and increasing omega-3s (from fish oil), the outcome was increased telomere length. This was due to a reduction of inflammatory molecules (cytokines) and oxidative stress, which was brought on by higher levels of omega-3s in relation to the pro-inflammatory omega-6s. There is a specific ratio between omega-6s and omega-3s that has to adhered to, to help prevent excess inflammation and for us to remain healthy. It is important to have both these omegas present in the body, so long as they are in the correct ratios.

An Important Note for Women

Women who consume a diet lacking in antioxidants tend to have shorter telomeres and present a moderate risk of developing breast cancer. On the other hand, a diet rich in antioxidants such as vitamin E, vitamin C, and beta-carotene have been linked to longer telomeres and a lower risk of breast cancer.

I mentioned previously about hormone deficiencies and decline, and the influence they have on the shortening of telomeres. Hormones decline with age, but supplementing with bioidentical hormones can aid telomere length. Oestrogen – 17 beta oestradiol – and testosterone activate telomerase which plays a key role in telomere length. However, estrogen blockers such as those given to women who have been found to have cancer, turn off or inhibit telomerase, as do androgen (synthetic male hormone) blockers.

So to help maintain telomere length… remember to take your antioxidants and vitamins, and for an even better outcome… bioidentical hormones as well!

Telomeres: Is Your Body’s Fuse Burning Out?

Could Your Body’s Fuse Be Burning Out?

Telomeres is a “hot subject” these days as they are considered to be an important factor in the ageing process, and although ageing is multifaceted, a host of research demonstrates that telomere length is as an excellent biomarker for ageing at the cellular level. The shortening of telomeres, over time, accelerates cellular ageing, however there are various nutrients that assist telomere repair and help maintain telomere length, that have proven health benefits.

What Exactly Are Telomeres?

They are often compared to the burning fuse; like this fuse, telomeres at the end of our chromosomes, steadily but surely shorten every time a cell replicates itself. Telomeres are a ‘time-bomb’ that hold the key to biological ageing; they are small strands of DNA code in our genes which control ageing and cell replication. In short, they help dictate how fast or slowly we age. Once they have reached a ‘critical point’ of shortness, cellular replication can no longer take place, which leads to ageing (senescence) of the cell and finally death, sometimes known as the “Hayflick limit process”. Ageing cells are not needed in the body and no longer contribute to efficacious tissue upkeep. And, in fact, telomere length is a very useful biomarker of cellular ageing.

Cells contain an enzyme (enzymes are special chemicals which speed up the body’s processes. Enzyme function declines with age) known as telomerase, which has the function of adding fresh new DNA to the ends of telomeres, assisting in keeping them long enough to support and maintain cellular health and activity.

What Circumstances Activate, Determine and Accelerate Telomere Shortening?

At every turn, we are faced with an internal (within our body) battle against negative forces. The eternal, endless and internal battle, wages war on our molecules, our cells, our entire body, as those forces actively work to destroy them. Our enemies in this war include: oxidation, glycation (a process that is damaging and toxic to the body), abnormal methylation (can lead to an increased risk of certain cancers, heart disease, stroke, neurodegenerative diseases, and other chronic issues.), inflammation, and DNA gene mutation. At the same time, we also have to face external influences; environmental toxins, unhealthy diet, overeating (a restricted diet has been associated with significantly longer telomeres and longevity), lack of exercise, smoking, nature of work/profession, stress, hormone and vitamin deficiencies. All of these trigger the shortening of telomere length.

At every level, life and longevity is a balance of factors. Just as love is a balance of growing, learning and understanding each other; a balance between freedom and trust: ageing is a balance between entropy and defense; degradation and restoration. We must learn to come together and understand it, and learn how we can protect our telomeres and therefore, our lives and our longevity.

Why are Telomeres More Important as we Age?

Our body is so intricately designed that the human infrastructure instinctively defends us from an attack. From the top and at every level, the body has specific systems in place to protect, minimise, restore and repair damage. But as we age, from approximately 30 years, the human infrastructure and its systems begin to break down. As the years and decades pass, the breakdown picks up speed, shifting gears from first, to second, and finally sixth gear.

Our body is no longer able to repair itself as it once did. Cells can’t recycle as well as they once did, and as a result, the damage in our body increases. We now get a shift towards more damage and decay (known as catabolic) from restore and repair (known as anabolic). Age-related defects in metabolism equate to increased pathology (disease). When the body slows, the restore and repair systems in place decline and, at the same time, the pace of telomere shortening increases. The erosion of telomeres plays a role in ALL diseases. Shortened telomeres are found in individuals with age-related disorders including neurodegeneration, cardiovascular disease, diabetes, and cancer.

In my next blog on Telomeres, I will explain how you can help to maintain their length with vitamin supplementation.
