Epigenetics shows how diet and lifestyle influence our genes. Find out which nutrients regulate epigenetic processes and can contribute to health.
Epigenetics describes the regulatory mechanisms of gene activity that take place without changes to the DNA sequence. While classical genetics assumes that genetic information is fixed and unchangeable, epigenetics shows that environmental factors, nutrition, stress and lifestyle can influence gene expression.
How does epigenetics work?
Epigenetic mechanisms control which genes are switched on or off and thus determine how cells develop and react to environmental stimuli. The most important epigenetic processes are:
- DNA methylation: A chemical modification of DNA that can permanently "mute" genes.
- Histone modification: Changes the structure of chromosomes and influences how accessible certain genes are.
- Non-coding RNA: Regulates gene activity by influencing specific sections of DNA.
Epigenetics, health and diseases
Epigenetic changes play a central role in the development of diseases such as cancer, diabetes, neurodegenerative diseases and autoimmune disorders. An unhealthy diet, environmental toxins, chronic stress and lack of exercise can negatively influence epigenetic mechanisms and increase the risk of disease. Conversely, healthy lifestyle choices can have positive epigenetic effects.
Epigenetics and dietary supplements
Certain nutrients and bioactive substances have the potential to positively influence epigenetic processes:
- Polyphenols (e. g. e.g. from green tea, turmeric, resveratrol): Regulate DNA methylation and protect against oxidative stress.
- Omega-3 fatty acids: Influence epigenetic mechanisms and have an anti-inflammatory effect.
- B vitamins (folic acid, B12, B6): Play a key role in DNA methylation and support cell functions.
- Spermidine: Promotes autophagy and can influence epigenetic ageing processes.
Epigenetics as the key to a healthy life
The findings of epigenetics show that epigenetics is the key to a healthy life
.strong data-end="2303" data-start="2239">health not only depends on genetic predisposition, but can also be actively influenced by nutrition, exercise, sleep quality and stress management. An epigenetically conscious lifestyle can help to reduce the individual risk of disease and promote cell health in the long term.
