I tend to agree with this take. Shifting from home cooked meals to processed meals probably has far more impact on diet and health than published guidelines.

The only nuance I'd add is that it doesn't follow that the optimal solution is for women to leave the workforce and get back in the kitchen. Domestic responsibilities can be shared by husbands and wives.

Also, when eating processed foods it's a good idea to pay attention to the nutrition information. Most people don't do much of this, which is why those published guidelines probably don't have much impact anyway. Those guidelines should be updated, and most people should probably start paying more attention to them.
