Epigenetics, what impact on my health?

Welcome to the exciting world of epigenetics, a field of biology that studies how our life experiences and our environment can influence the expression of our genes. What is epigenetics? In simple terms, it’s a science that explores how environmental factors, such asdiet and supplementationstress andexposure to toxins, can change the activity of our genes without altering the DNA sequence.

Epigenetics is a bit like musical notes on a staff. You have the same series of notes, but the way they are played can create radically different melodies. Genes are similar: they are the same in every cell of our body, but the way they are ‘played’ differs according to various environmental factors.

What impact does epigenetics have on health?

Epigenetics is a relatively new science, but already it offers astonishing insights into how our bodies and our health are influenced by our environment and our lifestyle. One of the most interesting aspects of epigenetics is its potential impact on our health, particularly as regards various diseases.

Epigenetics and cancer

Let’s start with cancer, one of the world’s leading causes of death. Cutting-edge research has shown that epigenetics plays a crucial role in the development and progression of cancer. Epigenetic modifications can activate or deactivate certain genes that control cell growth, leading to the formation of tumours. For example, DNA methylation, an epigenetic process, can deactivate genes that suppress tumours, paving the way for cancer development.

Cardiovascular diseases

Let’s turn now to cardiovascular disease, another group of diseases where epigenetics appears to play a crucial role. Traditional risk factors such as hypertension, smoking or diabetes cannot explain all cases of cardiovascular disease. Epigenetics could be the missing piece of the jigsaw. For example, epigenetic changes could influence the way the body reacts to atherosclerosis (the accumulation of plaque in the arteries), thereby altering the risk of heart disease.

The role of epigenetics in diabetes

Diabetes, in particular type 2 diabetesis another disease where epigenetics appears to have an impact. Environmental factors such as diet and exercise can lead to epigenetic changes that affect the way the body manages glucose, potentially leading to an increased risk of diabetes.

Neurodegenerative disorders

Finally, epigenetics could also play a role in neurodegenerative disorderssuch as Alzheimer’s or Parkinson’s disease. Epigenetic modifications could influence the expression of genes involved in these diseases, offering new avenues of research for their treatment and prevention.

Epigenetics and the environment

Epigenetics is not a science that operates in a vacuum. It is deeply rooted in the interaction between our genes and our environment. This connection is essential to understanding how our lives and choices can influence our health. Let’s take a closer look at how different environmental factors can impact epigenetics.

Pollution

Let’s start with pollution, a major contemporary scourge. Air pollutants, such as fine particles, have been linked to epigenetic changes. These changes can lead to inflammation and oxidative stress, which in turn are linked to various diseases, including heart and lung disease, and even certain cancers.

Stress

Whether psychological or physical, stress can cause changes in gene expression through epigenetic mechanisms. Studies have shown a link between chronic stress and changes in DNA methylation, which could have consequences for mental and physical health.

Diet: an epigenetic key

Certain dietary substances can influence epigenetic marks. For example, the folates present in green leafy vegetables can influence DNA methylation, while certain antioxidants can have an effect on histone acetylation, another epigenetic mechanism.

Chemical exposure and epigenetics

Finally, exposure to chemicals, whether they are present in our working environment, in our everyday consumer products or even in our medicines, can have an impact. Some of these chemicals can interfere with epigenetic mechanisms and influence gene expression, with potential consequences for health.

Epigenetics and psychology

The science of epigenetics extends far beyond pure biology. Its impact can also be felt in fields such as psychology. Indeed, epigenetics could provide explanations for how our life experiences and traumas can influence our mental health.

Life experiences and changes in gene expression

Our life experiences, both positive and negative, can leave epigenetic imprints on our DNA. These modifications could influence the way our genes are expressed, potentially affecting our mental health. For example, traumatic experiences, such as childhood trauma or post-traumatic stress, can cause epigenetic changes that could increase vulnerability to conditions such as depression or anxiety.

Epigenetics and sociology

Epigenetics can also help bridge the gap between biology and sociology. It could explain how the social environment influences our health and behaviour.

The social environment

An unfavourable social environment can induce epigenetic changes that influence our health. For example, poverty, chronic stress linked to discrimination or exposure to violence can cause epigenetic changes that can affect both physical and mental health.

Epigenetics and philosophy

Finally, epigenetics raises some fascinating questions from a philosophical point of view. These include debates about nature versus nurture, personal identity and moral responsibility.

Nature versus nurture

Epigenetics blurs the boundaries between innate genetic influences (nature) and environmental influences (nurture). It suggests that these two forces interact and mutually modify each other, challenging traditional conceptions of personal identity.

Moral responsibility

Epigenetics also raises questions about moral responsibility. If our behaviour and our environment can modify our genes and those of our descendants, what responsibility do we have towards ourselves and future generations? These questions are at the heart of many contemporary philosophical and ethical debates.

Modulating gene expression through nutrigenomics

Nutrigenomics stands out in the fascinating field of epigenetics, which explores the environmental impact on gene expression. This branch of science aims to studying the interactions between food and genomeand optimising them for personalised physiological well-being. Biocyte’s Lifegen range is the perfect response to this complex issue. Designed around targeted nutraceutical products, Lifegen addresses specific cellular mechanisms influenced by epigenetics. The range’s Cell Regenea complex combines antioxidants selected for their effectiveness against the effects of oxidative stress, which has a direct influence on gene expression and therefore on the ageing process. The Ematocell complex targets the absorption and bioavailability of iron, two factors closely linked to epigenetic regulation. Ultimately, Lifegen is positioned as a relevant solution to the physiological challenges posed by our unique genetic profiles, by exploiting advances in epigenetics and nutrigenomics.
