I don't understand people freaking out over this - outside of a purely political reflex - hell hath no fury like taking away nerds' Mountain Dew and Flamin' Hot Cheetos.
Nor do I understand the negative reactions to new restrictions on SNAP - candy and sugary drinks are no longer eligible.
The sources of those macronutrients also matter. The ideal range for saturated fat is 5-10% of total calories. Meat consumption, especially red meat, is associated with higher risk of colorectal cancer. Dairy consumption is associated with higher risk of prostate cancer.
I haven't read the new guidelines in detail but if they're recommending red meat and whole milk as primary foods, then they are not consistent with the research on cancer and cardiovascular disease risk and I doubt that people following them would meet the AMDRs or ideal saturated fat intake.
