Nutrient-dependent cell type differentiation

Our Tastes For Certain Foods May Be Written in Our Genes

Excerpt: “Together, the series of studies bolsters a branch of research called nutrigenetics, which focuses on understanding the way our genes affect our choice of foods and our body’s ability to process these foods.”

My comment (Discover did not approve it):

Nutrigenetics is nutritional epigenetics because the nutrients epigenetically effect cell type differentiation, which is how they change behaviors.

Nutrient stress and social stress induce receptor-mediated changes in behaviors associated with ecological variations that must result in ecological adaptations via cell type differentiation for individuals of different species to survive. The result is biodiversity.

Olfactory receptors: Mosaic Epigenetic Dysregulation of Ectodermal Cells in Autism Spectrum Disorder 

Are ASDs the disorders of nutrient-dependent cell type differentiation most closely linked to the epigenetic effects of pheromones on social behavior?

News sources often limit accurate representations of biologically based cause and effect and tout the pseudoscientific nonsense of population genetics.  The Discover blog D-brief reported that genes are responsible for the development of our food preferences. My comment cited works that link experience-dependent de novo creation of taste receptors and olfactory receptors to the hormone-organized and hormone-activated development of food preferences across species from insects to humans.

If my comment is not published, uninformed readers will continue to assume that food preferences are genetically determined despite experimental evidence that clarifies what is currently known about nutritional epigenetics, which they call “nutrigenetics” because they do not understand how the epigenetic landscape becomes the physical landscape of DNA  in the organized genomes of species from microbes to man.

About James V. Kohl 1308 Articles
James Vaughn Kohl was the first to accurately conceptualize human pheromones, and began presenting his findings to the scientific community in 1992. He continues to present to, and publish for, diverse scientific and lay audiences, while constantly monitoring the scientific presses for new information that is relevant to the development of his initial and ongoing conceptualization of human pheromones. Recently, Kohl integrated scientific evidence that pinpoints the evolved neurophysiological mechanism that links olfactory/pheromonal input to genes in hormone-secreting cells of tissue in a specific area of the brain that is primarily involved in the sensory integration of olfactory and visual input, and in the development of human sexual preferences. His award-winning 2007 article/book chapter on multisensory integration: The Mind’s Eyes: Human pheromones, neuroscience, and male sexual preferences followed an award winning 2001 publication: Human pheromones: integrating neuroendocrinology and ethology, which was coauthored by disinguished researchers from Vienna. Rarely do researchers win awards in multiple disciplines, but Kohl’s 2001 award was for neuroscience, and his 2007 “Reiss Theory” award was for social science. Kohl has worked as a medical laboratory scientist since 1974, and he has devoted more than twenty-five years to researching the relationship between the sense of smell and the development of human sexual preferences. Unlike many researchers who work with non-human subjects, medical laboratory scientists use the latest technology from many scientific disciplines to perform a variety of specialized diagnostic medical testing on people.
