To partially answer the thread question, government is working off an older model. Agriculture subsidies were initiated during a time (pre-WW2) when people couldn't get enough to eat in general. The goal was to get ANY calories to starving people, first here in the US, and later to the Third World. Grains are easy to grow, provide the most calories for the effort, are easy to ship, and are practically non-perishable. Big Ag was only too happy to supply grains for the government to buy and send overseas, and that influence continues to this day.
The government doesn't yet realize that modern wheat is NOT the same as the wheat from even 40 years ago. They don't realize that CICO is, at best, 1/3 of what really happens. Heck, we can't even get this Primal forum to agree on CICO -- so we certainly aren't going to influence Big Ag or the government.
Back to the conspiracies: ... What if the government suddenly did embrace Primal, and started a crusade to pass regulations in that direction? Then we'd just get a different -- and much larger and wealthier -- set of people accusing the government of a different leftist nanny-state conspiracy, this time to force us to eat bacon and that hateful broccoli, and to ditch the wheat which has sustained us througout recorded history. In fact, even the smallest steps have already drawn fire. Michelle Obama DID try a very mild one-woman crusade against juice boxes, and she was lambasted. Michael Bloomberg tried to tax Big Gulps and he is still vilified for it. The government is just -- as you say -- saying the safe thing, what everyone else is saying.
