Even though we are unable to change our genetic code, we can influence how our genes are expressed.
Epigenetics is a word that describes how our diet, lifestyle and environment can influence our genes. The human genome project taught us that nutrition and dietary habits , toxic load including heavy metal and chemical, mental attitude and environmental stressors can express genes in certain disease processes.
The combination of genetic understanding along with knowledge of the methylation cycle can help us make personalized lifestyle and supplement recommendations to optimize genetic expression and overall health.
There has been a lot of attention and focus on the single gene MTHR, (methylenetetrahydrofolate reductase) and its potential impact on several health conditions. However, recently more focus has been on the entire methylation pathway which has proven to be more effective in predicting disease as well as personalizing nutritional needs to optimize ones health.
