Grains can support a large population even while causing dementia in later life. The two are not incompatible.

  That's maybe true but doesn't mean anything. As far as I know there is no reason to suggest grains specifically cause dementia, and as I said the article doesn't do a good job showing that it is specifically grains and not the obesity itself which causes the issues.

    Having not read the book, I imagine the argument is that grains are carbs and carbs cause obesity and dementia. Most Americans over consume refined grains [1] despite the government drastically reducing grains share of the food pyramid.

      Which does not point to grains causing dementia, being poison etc., it points to overeating being really bad for you. Possibly that has to do with carbs, probably not because your body ends up doing pretty similar things with an overabundance of fat or protein. The difference is these foods make you feel fuller, and so you are less likely to overeat them. But there is still little evidence that overeating one specific macronutrient is worse for you than another.
