Sceptical of grains and wine recommendation and sceptical that red meat is discouraged.

Wine/meat results seem likely to be confounder related. Wealthy and educated people self-selecting into red wine because they read somewhere it's ok, and fast-food eaters having lots of beef. Grains seem like an old food pyramid propaganda thing, although I'm open to having my mind changed on that if someone has a study I can read on it.
