People are forgetting we had famines a few centuries ago in the west, and still have famines in many places. Sure, they are also usually associated with governing issues and other complicating factors, but still. The number of peoole being alive is my answer to whether food manufacturing is a net negative or not.

While the pendulum has swung way past the equilibrium for us, rejecting whole categories of food that tend to be nutrious, easily preserved is just not realistic.

To me there are dozens of other levers we can pull to deal with health improvement. As pointed out in the other threads, not all OECD countries are facing what the US are facing.

PS: do I get all my points accepted as truth if I can prove a BMI that satisfies you ? Would 22 do it ?
