In Defense of Food: An Eater's Manifesto by Michael Pollan

Seven words: "Eat food. Not too much. Mostly plants."

That's Pollan's entire argument. The rest of the book explains why we need to hear something so obvious and how we got so far from it.

Pollan's central claim: we stopped eating food and started eating "nutrients." The food industry, with help from nutrition science, reduced eating to a checklist of vitamins, minerals, and macronutrients. The result? We eat more processed products engineered to hit nutritional checkboxes while making us less healthy.

He calls this "nutritionism" — the ideology that food's value lies in its individual nutrients rather than the whole. It's a compelling critique. I recognized myself in it. How many times have I grabbed something labeled "high protein" or "low fat" without asking whether it's actually food?

The historical argument is fascinating. Pollan traces how the Western diet shifted from whole foods to processed products over the last century. Government subsidies, food industry lobbying, nutritional science that keeps contradicting itself — it's a systems problem, not an individual willpower problem.

Where Pollan is strongest: his practical advice. Eat food your great-grandmother would recognize. Shop the perimeter of the grocery store. If it has more than five ingredients, think twice. These rules are simple and memorable. I've adopted several and noticed the difference.

Where he's weaker: Pollan writes from a position of privilege. Eating whole, unprocessed food is more expensive and time-consuming. Not everyone has access to farmers' markets or the luxury of cooking from scratch every night. He acknowledges this briefly but doesn't grapple with it seriously.

His critique of nutrition science also paints with too broad a brush. Yes, the field has contradicted itself. But that's how science works — through refinement, not final answers. Dismissing nutritional research wholesale feels like throwing out the baby with the bathwater.

Read this if you want a clear-eyed look at how modern eating went wrong and a simple framework for fixing it. Just keep in mind that "simple" isn't the same as "easy" for everyone.
