Key Takeaways:

• McCann launches a fierce attack on the rise of processed, bleached, chemically treated foods, arguing that they rob the public of essential nutrients.
• He portrays the food industry as willing to sacrifice health for profit, using scientific language and vivid rhetoric to stir public outrage.
• The book calls for stricter regulation and honest labeling, anticipating later pure‑food and consumer‑protection movements.
• Food choices are framed as moral and even spiritual decisions: to eat denatured food is, for McCann, to violate natural and divine law.
