“Genetic diversity reflects evolutionary pressures
from environmental changes, principally climate and diet.”
Most people are familiar with the DNA code and that the genes we are born with are for keeps. However, whilst it is true that we cannot change our genes, epigenetics – the study of gene expression alterations via external factors such as diet, lifestyle and environmental factors – has shown that the way we choose to live can have a profound impact on our health. So depending on these external factors, the way in which our genes behave within the body can be modified, although the DNA sequence will remain unchanged.
Certain chemicals found in pesticides, cosmetics and household cleaning products, amongst others, are known to cause harmful epigenetic changes via DNA damage. In contrast, some food components such as those found principally in fruits and vegetables are known to reduce this damage and aid positive gene expression. There is an increasing belief that epigenetics may in fact have a greater role in disease than genetics as it becomes clearer that factors within our control, like diet, can affect our chances of disease, whichever genes we may have inherited. This applies to an almost limitless range of conditions from foetal health, cancer and diabetes through to ageing.
Epigenetics is the reason that a one diet fits all approach to nutrition and lifestyle is inadequate. Just as we all have our own unique genetic code, we all require unique dietary advice, which is what Nutritional Therapy is all about. Your biochemical individuality will be taken into account by means of a detailed health analysis and, if deemed necessary, laboratory testing, before your personalised nutrition plan is recommended.
