What is Nutrigenomics? What is epigenetics?

Nutrigenomics is the scientific study of the way specific genes and bioactive food components interact. It provides a basis for understanding how the health consequences of eating behaviors may vary across individuals. This information is key to a personalized approach to nutrition in a clinical environment. Because epigenetic events such as methylation can be changed, they offer another explanation for how environmental factors such as diet, can influence biological processes and phenotypes.

What is epigenetics? “Think of this way: Epigenetics is the on-off switch to the dimmer on your dining-room chandelier. The gene is the lightbulb, the epigene is the

light switch. If the lightbulb is defunct or the switch is frozen in the “off” position, the dimmer function is useless. Likewise, epigenes control the effect to which the gene turns on.

Altered nutrition also appears to be the primary driver of altered epigenetics. For example, the vitamin, folate is a necessary cofactor for the enzymes called DNA methyltransferases, which add a methyl group to DNA to alter whether genes are being activated. Folic acid is so important to normal fetal development in order to prevent the occurrence of spina bifida that the FDA and mandated to be added to store – bought bread.

Other nutrients at work here – vitamin B12, B complex vitamins, retinoic acid (vitamin A). circumin, sulforaphane, and polyphenols and others that moderate this process.”
