The LA Times Health section (well, yeah) ran an article this morning about the theory that today's obesity epidemic originated in the eating and other habits of women in the 50s and 60s. It attributes the problem to epigenetic changes caused by the pre-natal and natal environment.
Now, epigenetic effects are real, so this isn't inherently impossible. Questions, though:
If obesity and related problems can be substantially reduced or eliminated by eliminating "neolithic agents of disease", wouldn't that undercut the epigenetic theory? Or does it just mean both might be true?
Anybody know of any studies on the epigenetic consequences of ancestral diets?
