What do you want a citation for? Which claim?

Your claims that (1) the food pyramid put whole grains at the base, and (2) that there is any consensus at all that a healthy diet should include more whole grains than fruit and vegetables (which is what "being at the base of the pyramid" means).

Sure, here's a USDA article referring to the "1984 Food Guide Pyramid" where it states cereals should be whole grain (see p38: https://www.ers.usda.gov/webdocs/publications/42215/5831_aib...)

As for whole grains vs fruit vs vegetables, here's a SR and MA of studies looking at different food groups and the RR of all cause mortality: https://www.sciencedirect.com/science/article/pii/S000291652...

Three servings of whole grains per day: 0.79 (21% reduction in ACM) Three servings of vegetables per day: 0.89 (11% reduction in ACM) Three servings of fruit per day: 0.90 (10% reduction in ACM)

So the evidence seems to support the suggestion that consumers should focus on whole grain consumption as a base for their diet.

> Citation please or I'm calling extreme bullshit. Everything I've ever read has argued for putting more nutrient dense fruits and vegetables as the basis for a healthy diet.

Wut? Was your comment a joke or satire? This entire thread is about how the food pyramid of that era was an unscientific disaster, so linking to a picture of it is not evidence.

you asked for citation of pyramid putting grains in foundation, you got it, not sure what you are complaining about now.

Sorry, I realized now, I quoted that section just to give context. I was really referring to "Not sure why you consider this objectionable, the body of evidence overwhelmingly points in the direction of benefits for wholegrain consumption."

Even with that first sentence though, the base of that shitty food pyramid really just doesn't talk about "whole grains" - it calls it the "bread, cereal, rice and pasta" group, with a graphic that includes spaghetti, crackers, a baguette, a bowl of cereal, etc. And having lived through that time when the food pyramid was taught in school, they certainly weren't delineating between highly refined flours and things like oatmeal, brown rice, quinoa, etc.

looks like I agree with you on this part: https://news.ycombinator.com/item?id=41964513

If Americans actually stuck to the food pyramid they would be fine. No one does. It needed refinement to “eat whole grains and pasta, brown rice”, but it was hardly a disaster, the disaster is lack of people (adults) paying attention to it and instead eating crap out of boxes loaded with sugar, hydrogenated fats, and lots of ingredients they couldn’t pronounce let alone know how healthy or unhealthy they are. I saw lots of people paying lip service to it, but few people were sticking to it. Same with the current “my plate” ideas. People won’t tsit for 10 minutes and understand what they mean by protein, veggies, grains, and fruit.
