Your entire genetic code contains around 3 billion nucleotide pairs. These 3 billion base DNA pairs in each cell fit into a space just 6 microns across which means it is only possible to see them under a powerful electron microscopes. Interestingly, if you uncoiled and stretched the DNA in one cell all the way out into one thin thread, it would be about 2m long and all the DNA in all our cells put together would stretch to the moon and back many times over!
While all humans are genetically very similar, we all have slight differences in our genetic profile which set us apart from other people. It is the combination of these tiny differences that defines our individuality and make us unique!
There are the differences that we all see, such as eye and hair colour, but there are also the differences we don’t see, such as how we metabolise nutrients, our response to certain drugs or our susceptibility to certain diseases.
Nutrigenomics is the study of nutrition and genomics which helps us discover the different ways that individuals respond to food based on their genetic make-up.
