Arthur De Vany's Evolutionary Fitness Art's Blog on Fitness, Health, Aging, Nutrition and Exercise

We have nutrigenomics---the study of the effect of nutrients on gene expression---and metabolomics---the study of the whole of the metabolic activators circulating in the body. The idea of functional food or nutraceuticals comes from these areas of study. They are not close yet to achieving the level of knowledge required to fulfill the ideal of prescribing nutraceuticals since they have only partial maps of the genetic pathways and the combinatorial aspects of the gene/nutrient interactions, but some sensible warnings, particularly regarding excessive nutrient intakes in childern have been established.

I want to coin a name---activegenomis---for the next field in the study of gene expression and epigenetic factors. Activegenomics studies the full range of alterations in gene expression caused by activity. That is the only way one can seriously address the contemporary problem of how the evolutionarily stable active genotype can promote a healthy expression of that genotype in a world where being inactive does not threaten survival.
