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.
When we think of aging, we often envision wrinkled skin, sagging bones, and brittle hair. These are all part of the aging process but what if we didn’t have to go through this as our bodies simply don’t age? That is what Gene Therapy does. It replaces our body’s genetic code with the genes of another person that causes our body to function correctly. This is done by inserting a DNA copy of a healthy donor into the patient’s body.
For a person who is interested in finding out what potential does gene therapy has for our lifespan, they first need to understand how it works. This treatment uses healthy tissue to treat cancerous cells. Basically, these are stem cells that have been modified to attack cancerous cells when they are not in an appropriate state. In addition to that, some of these stem cells will also be used to replace damaged or dead brain cells that have already been removed during the treatment process. These stem cells will not be harmful to your body in any way, and in fact they will help to rejuvenate your body and bring back the health that you had when you were younger.
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?
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.
