So funny to see people reflexively defend those things being left off because it confirms their own beliefs. A deeper inspection of the actual guidelines has them being very fair to plant proteins:
> Consume a variety of protein foods from animal sources, including eggs, poultry, seafood, and red meat, as well as a variety of plant-sourced protein foods, including beans, peas, lentils, legumes, nuts, seeds, and soy.
The thing is... the pyramid is just a graphic, the actual words give more context.
Since we're talking about the actual wording of the report, it admitted the significance of previous reports deciding to order plant foods before animal products. That is reversed in this most recent report, and very intentionally, which they make clear. They also pretend that the health effects of saturated fat intake are still fuzzy, as if the evidence doesn't heavily point towards it being detrimental.
If anyone is holding to unshakeable beliefs and unwilling to consider evidence, it's the shoddy scientists (many with meat-industry related conflicting interests) that wrote the report.
