Children’s healthy diets lead to healthier IQ

Excerpt: “While the differences in IQ are not huge, this study provides some of the strongest evidence to date that dietary patterns from six to 24 months have a small but significant effect on IQ at eight years of age,” Dr Smithers says.
My comment:
The article attests to the predictive explanatory power of modeling behavioral development based on what is already known about the molecular biology that is common to species from microbes to man.
Nutrient chemicals and pheromones are unequivocally required for adaptive evolution (i.e., of behavior) via ecological, social, neurogenic, and socio-cognitive niche construction as detailed in Human pheromones and food odors: epigenetic influences on the socioaffective nature of evolved behaviors.
Newsgroup discussions about IQ seem to proceed in the absence of the minimal intelligence required by some people to inform themselves about the currently available neuroscientific facts. See, for example Variation in Cognitive Abilities Attributable to Composite Metabolic… Instead, we have random mutations theory (Clarence ‘Sonny’ Williams), domain-specific modules (Clarence ‘Sonny’ Williams), logico-/psycho theory (Edgar Owen) and denial of the epigenetic effects of nutrient chemicals and pheromones on IQ (Bee Doubleu).
Studies like the one reported today require replication. Models for behavioral development cannot be compared unless there is more than one. The epigenetic effects of nutrient chemicals and pheromones during the first 24 months of life are clearly the most important factors involved in the development of the brain and and behavior because there is no other model that links sensory input from the environment directly to intracellular signaling and stochastic gene expression as is unequivocally required to link the sensory input directly to its effect on hormone secretion and the affect of those hormones on behavior during its development.
