Thanks for this. Another thing: In 1950, despite "conservative" memes that suggest otherwise, Americans ate less meat, with middle and lower-income families often reserving it for special occasions or certain days of the week. It was much less of a staple then and was relatively higher-priced compared to other foods. One of the main trends since 1950 has been a fall in relative meat prices and a vast increase in meat consumption. Part of this was due to new "preservative" and "processing" techniques.
