A challenge to all GMO supporters.

108. To the contrary, there have been multiple studies of epigenetic effects of nutrition.

I wonder why you just assumed there were none.

Recent studies have shown how nutrition dramatically alters the health and appearance of otherwise identical mice. A group led by Randy Jirtle of Duke University demonstrated how mouse clones implanted as embryos in separate mothers will have radical differences in fur color, weight, and risk for chronic diseases depending on what that mother was fed during pregnancy.
That is, the nutrients or lack of thereof changed the DNA environment in such a way that the identical DNA in these mouse clones expressed itself in very different ways.

Building upon this Duke University work, a new study led by Torsten Plösch of University of Groningen, The Netherlands, delineated the numerous ways in which nutrition alters the epigenome of many animals, including adult humans. The paper has been submitted to the journal Biochimie with lead author Josep C. Jiménez-Chillarón of the Paediatric Hospital Sant Joan de Deu, in Spain.

The researchers said that the diet of human adults induces changes in all cells — even sperm and egg cells — and that these changes can be passed on to offspring.

Hints of this were reported in a 2011 paper in Nature by Stanford University scientists who found lingering, positive effects on longevity from nutrition on three generations of the C. elegans worm.
