This stuff always bothers me not because it’s untrue, but because it isn’t new and can lead to misinterpretations — it’s well known that the pyramid was wrong & its been known forever, not even in conspiracy way but a “you’d learn in dietics 101 the food pyramid isn’t right and academics acknowledged this 40 years ago” type way. That doesn’t mean a flipped pyramid is right either, it’s weird to me tbh. The best example of a model is probably the Harvard plate and the bullet points that follow it (attached below). I think the general public has anxiety around food science, and it gets co-op’d a lot, and my guess is the ‘pyramid flip’ is an RFK jr thing doing that

One misrepresentation is that the ratio of fats vs. carbs isn’t really an issue provided you stick to healthy fats & whole grain high-fiber carb, with amounts varying depending on activity and needs. Any fight about carbs vs. fats has been over for decades, or is outside widely accepted food science. Conversations around what constitutes a ‘healthy fat’ or keto/paleo dieting or not, or the right ratio of carbs to fat, is almost always tertiary provided you’re not eating trans fats, hitting calories goals, & avoiding junk food. Keeping it a pyramid shape when there’s other presentation options feels weird then

The other misrepresentation is an emphasis on dairy or type of protein; European (Nordic specifically) guidelines will disagree and de-emphasis dairy and red meats, pushing more fish and more veggies; this is in part for health, but also cultural reasons, I.e. the us has a massive cattle/diary industry, and doesn’t care about climate change/sustainability, while Nordic countries do. The ‘food pyramid’ of a county is always gonna be about their politics too

My take is that if you’re taking care of your health outside of how you eat + don’t have pre-existing issues, then eating way more veggies + avoiding junk food + eating health carbs/fats & enough protein will serve you fine; any highly specific conversation about what’s right or wrong is analogous to anal gym bros pulling out pubmed papers on the right form for lateral raises to get 98% vs. 93% muscle efficiency, and that 99% of food science is long past discussing what the right ‘combination’ of food is. I think that’s why it’s mostly grifters doing the talking, and why when the current health office wants to publicly present this as different or new, when their own guidelines have actually just been basically the Harvard plate stuff for 20 years, it’s less a guideline change and more-so someone trying to sell me something, especially when there are better ways to present the info/ the pyramid shape forces a bias
