How well your genes are expressed can have a profound impact on your health. Read on to find out if you can change genetic expression and what you can do to optimize your health.
So what is gene expression? In simple terms, gene expression is the process used by our body to make functional products from the instructions in our DNA. Once a product has been made the gene has been ‘expressed’.
While you can’t change your DNA, you can change your genetic expression to target specific health issues to improve your overall well-being.
Gene expression is a biological process, and like all biological processes, how efficiently it occurs from individual to individual is variable rather than exact.
Some aspects of this variability are predetermined by genetic variation, ultimately some people just have better functioning genes, which is why they are more (or less) prone to things like weight gain or inflammation than others.
Another variable that can change genetic expression is the environment you’re in, which we’ll explain in more detail below.
So your genetic disposition and your environment can impact gene expression, but why should you care? The answer is simple, because how well our genes function influences how healthy we are. For example, if you have a poorly expressed LCT gene, you will produce less lactase and are therefore more likely to be lactose intolerant.
This is why if you want to live the best life possible in full health, it’s important to know how well your genes are functioning, so you can make positive changes where necessary to provide your body with the optimal environment to function properly.
The best way to find out how well your genes are functioning is to use a service like SelfDecode, who not only provides you with comprehensive reports on your genetic predispositions but also tells you which environmental changes can counteract the negative genes you may carry.
Certain environmental factors cause changes within our bodies, which influences how well we are able to read the instructions in our DNA. As a result, these environmental factors lead our body to function better or worse.
The number of environmental factors which can impact how well our genes work is pretty high, and scientists are discovering new factors at an increasing rate. That’s why using a tool like SelfDecode can help you understand what can change your genetic expression and keep you up to date with the most accurate scientific research.
The most obvious environmental factors when it comes to humans are of course our diet, lifestyle and environment (things like exposure to toxic substances). Still, there are many variables that can affect these three factors alone, so it can feel overwhelming if you want to optimize your health based on your genetic predispositions and don’t use the right tools.
So, if the environment your genes are being expressed in is not optimal, or your genes are functioning poorly and this is contributing to adverse health, can you do something to change this?
Lots of the environmental factors linked to gene expression are within our control. These include things like eating enough essential vitamins and minerals, getting enough exercise, and managing stress. The best way to optimize gene expression is by following personalized recommendations to target specific genes which may be contributing negatively to your health conditions.
A working example of how you can influence your own gene expression to optimize your health is the NEGR1 gene. Some variants of this gene are expressed at an increased rate and have been associated with increased rates of obesity.
But there are several environmental changes you can make to counteract carrying one of these genetic variants. The Mediterranean diet for example, which is rich in fruits and vegetables, has been shown to decrease NEGR1 gene expression and could therefore lower your risk of obesity.
Genetic expression is a process in which our bodies create vital components using the instructions written in our DNA. The efficiency of this process is governed by genetic variation and environmental factors such as diet and lifestyle.
Whilst over and under active genetic expression can be a recipe for poor health, the good news is that you can identify any genetic variants which may cause you problems and make targeted changes to your environment to optimize your health by using services such as SelfDecode.
