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.
Is this true? Specifically, "devised by" vs "influenced by" and "never based on science" meaning there was no, for example, attempt to improve heart disease rates?
In any event, looking at the whole history of food guidance paints a clearer picture of my point. Happy to hear of alternatives though!
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.
I'm clearly not advocating against basic safety oversight. It's worth noting that The Jungle was a work of fiction and Sinclair famously fabricated a lot of details wholesale.
