Nutrition and your DNA: What is epigenetics? July 29, 2012 By: Donna Sundblad

Excerpt: You’ve heard the saying, “You are what you eat.” While there is truth behind that statement, epigenetics show diet may also influence your DNA and the DNA of future generations.

My comment: Now that others are talking about the epigenetic effects of nutrient chemicals, it should not be long before more people realize that the epigenetic effects of pheromones are equally important to adaptive evolution via ecological, social, neurogenic, and socio-cognitive niche construction, as I detailed in Kohl (2012).

The clearest common link across the molecular biology of species from microbes to man is the conservation of gonadotropin releasing hormone (GnRH), and diversification of its receptor. In our species, as in other mammals, the measure of luteinizing hormone (LH) reflects sex differences in brain development and their link to GnRH-directed neuroendocrine and neuroimmune system development as is important to consider in autism spectrum disorders, and every other aspect of genetically predisposed brain development. See also our pioneering work: From fertilization to adult sexual behavior. Diamond M, Binstock T, Kohl JV. Horm Behav. 1996 Dec;30(4):333-53.

Proceeding from the quote above “You are what you eat.” –> The metabolism of nutrient chemicals (what you eat) determines the pheromone production that tells others who and what you are, as exemplified in the honeybee model organism (and in yeasts). What the queen bee eats determines her pheromone production and everything else about the interaction in the colony, including the neuroanatomy of the worker bees’ brains.

Did those who say that diet may influence the DNA of future generations not get my memo? Of course there are transgenerational epigenetic effects of diet (and pheromones). They are responsible for adaptive evolution via ecological, social, neurogenic, and socio-cognitive niche construction – as occurs with speciation from microbes to man.

The transgenerational epigenetic effects of diet and pheromones cause speciation. A new nutrient source in an existing ecological niche causes diet-driven changes in intracellular signaling and stochastic gene expression.  The changes in gene expression are linked to the metabolism of the new nutrient and to changes in pheromones and in chemical (e.g., olfactory or odor receptors).

Substantial changes in diet result in substantial changes in species-specific pheromones that signal reproductive fitness. Natural selection for a well-nourished conspecific that is reproductively fit is ensured via the epigenetic effects of nutrient chemicals and pheromones. Had Darwin’s followers known anything about genetics they might have figured out the the changing beaks of finches were caused by the epigenetic changes of nutrient chemicals and that even subtle changes in the beaks were accompanied by changes in pheromones that controlled reproduction — so that different species with different beaks could evolve to maximize their reproductive potential in a new ecological niche. As it turns out, now we know that nutrient chemicals and pheromones are responsible for evolution. What we don’t know is why so many people think that random mutations cause adaptive evolution. Is there a model for that? If so, is there a pattern comparable to the one recognized as the design in biology of 1) ecological, 2) social, 3) neurogenic, and 4) socio-cognitive niche construction?  How could random mutations be responsible for such an obvious complex sequence of receptor-mediated events?

James Kohl owns, and he has published books and award-winning research journal articles about human pheromones. With colleagues he was the first to show that a mixture of human pheromones increases the flirtatious behaviors of women, and increases their level of attraction to the man wearing the mixture - during a real-life social circumstance lasting 15 minutes.

What is the vomeronasal organ (VNO)?

The vomeronasal organ (VNO) is a cone-shaped organ in the nasal cavity, which is believed to be one of the body's receptors of pheromones. More, specifically, the VNO, which is part of the accessory olfactory system in the nose, does not respond to normal scents, but may detect odorless, barely perceptible pheromones.

Other schools of thought believe that it is not the VNO but rather cells in our main olfactory system and their affects on hormones secreted by the hypothalamus that are responsible for the affects of pheromones.

What are optimized pheromones?

Optimized pheromones are lab-certified pheromone formulations that have the optimum concentration of biologically active pheromones scientifically proven to produce behavior-altering results -- particularly as sexual attractants. Optimized pheromone formulations do not necessarily contain the maximum level of pheromones available on the market, but rather contain the greatest degree (and combination)of human pheromones that trigger a conditioned biological response in humans that, in turn, dictate their sexual behavior. Optimized pheromones also release neurotransmitters that directly modify the behavior of the opposite sex, such as triggering sexual excitement. For example:

Optimized pheromones for men are scientifically proven to bring about an increase in the luteinizing hormone (LH) in women, thereby causing a woman to have a heightened sexual responsiveness to a man. This LH surge elevates a woman's predisposition towards sexual activity.

Optimized pheromones for women are scientifically proven to bring about a biochemical surge in men, thereby causing a man to have a heightened sexual responsiveness to a woman. This biochemical surge is what makes a man fiercely determined to copulate.
