I'd strongly prefer the government just not try to tell people what to eat, the incentives will always be perverse and nutrition science is anything but science in most cases.
EDIT down-thread to prove my point you'll see people citing studies in favor of and against the new recommendations. The studies are almost always in animals or use self reported data with tiny sample sizes.
> not try to tell people what to eat
food industry has to be policed -- The Jungle by Upton Sinclair is a high school level story featuring the meat packing industry. All around, additives and substitutes are more profitable than raw ingredients.
The whole point of government performing the function is that they don't profit from misleading you, rather their goal is the country's welfare.
Obviously there are exceptions - particularly right now - but those are solved by rooting out corruption.
