Rise of Chronic Diseases Since 19th Century

Seed Oils Replace Animal Fats
- Seed oils entered the American diet post-Civil War, replacing animal fats by the 21st century.
- They were marketed as healthy despite chemical processing and lack of evidence separating them from other fats in studies.
Seed Oil Consumption Exploded
- By 2010, Americans consumed about 80 grams of seed oils daily, equaling roughly 720 calories.
- This massive intake stems from profit-driven production since seed oils never entered food for health reasons.
