Consider that economics (i.e. food board lobbying) as much as Nutrition Science has historically shaped our USDA nutritionists' dietary recommendations. The Texas Beef Council just may have (and of course they did) lobbied to ensure red meat's prominence as an immutable, foundational keystone for that pyramid you cite.

Humans can't survive without meat.

And what, you gurgled that for us here because there is no such creature as a surviving Vegan, I guess?
