Through most of civilization, people have been getting the majority of their calories from whatever carbohydrates were available: bread, potatoes, rice, or yams depending on location. But in the last couple hundred years, food technology and culture has upended that. This video from Data is Beautiful tracks the source of caloric intake among Americans aged 20-39 from 1930 to 2026. Keep in mind this does not take into account the total amount of food consumed; just a comparison of the calorie source. That's why fruits and vegetables stay so low- you can eat an awful lot of those and still get few calories.
Bread stays at the top during the Great Depression. Then when World War II vets came home, they continued to eat red meat every day like they did in the military, and their families did, too. Then the rise of fast food took over, and soda pop became an everyday drink. Late in the 20th century, red meat became less popular and more expensive. You'll spot more trends on a second watch that can be linked to prices, trends, and health concerns. (via Born in Space)
