Personal preference has dictated nutritional choices throughout contemporary history. Ever since people gained access to enough food to move beyond subsistence nutrition, they have based their dietary decisions mainly on taste and general health trends. Yet a growing body of evidence shows there is no one-size-fits-all approach to nutrition. Our responses to different nutrients are unique, and by recognizing and monitoring this we can potentially extend our healthy life expectancy.
Nutrigenomics is a subdivision of nutritional genomics and is the study of the various effects of the foods and the food constituents on the gene expression. It is an emerging field in the gene expression research domain that focuses on identifying and comprehending the interaction between nutrients and other dietary bio actives at the molecular level with the genome.
Scientists have, for years now, been experimenting with how to treat the human condition at its most basic levels. That is, by altering the building blocks themselves, which make up our biology. While we are, at the moment, taking baby steps into this brave new world, it would seem inevitable that at some point in our future, near or far as that may be, science will tame our genetic code. Instead of going to the beauty parlor, will we simply be able to turn on a gene for blonde hair? Will we be able to live out extended lives in a disease free body, designed to our own exacting standards?
