2Michael Pollan's In Defense of Food: An Eater's Manifesto critiques the modern Western diet and its reliance on "edible foodlike substances" over real food. It argues that the focus on nutritionism, or the belief that food is primarily about nutrients, has led to unhealthy eating habits and widespread confusion. The book examines the historical and ecological context of the Western diet, revealing how industrialization has simplified our food and damaged our health. Pollan contrasts this with traditional diets, highlighting their diversity and the wisdom embedded in cultural food practices. He advocates for a return to simpler, more natural eating habits: "Eat food. Not too much. Mostly plants." The manifesto also offers practical advice for navigating the complex world of food choices and reclaiming pleasure in eating.

- Late 19th/Early 20th Century:
- Rise of Food Fads: Dietary exertions remove eating from social life and pleasure (e.g., Horace Fletcher and compulsive chewing).

- Mid-20th Century:
- Ancel Keys promotes the lipid hypothesis, linking dietary fat to heart disease, although this was later challenged.
- 1977:
- "Dietary Goals for the United States" are published, recommending reduced fat consumption, which some argue inadvertently promoted increased consumption of refined carbohydrates and processed foods.
