the.com/food pyramid

means A diagram that stacks food groups into tiers to suggest how much of each you should eat, from a wide base of grains up to a tiny tip of fats and sweets.

from The shape traces to a Swedish 1970s 'food circle' and similar graphics in Western Europe, but it was the USDA's 1992 pyramid that cemented the form in public memory, replacing earlier 'basic four food groups' charts. The pyramid shape itself wasn't scientific — it was chosen for visual clarity, to show proportion and hierarchy at a glance. It proved so confusing (why would bread be the foundation of a monument to eating?) that the USDA scrapped it in 2011 for MyPlate, a simple divided circle — because, as it turns out, people understand plates better than tombs.
