“Eat food. Not too much. Mostly plants.” With those simple words, Michael Pollan captures his common-sense approach to better health. In the slim volume Food Rules: An Eater’s Manual, the author of The Omnivore’s Dilemma reminds us that diet and nutrition are not as complicated as they are often made out to be. On the contrary, complicating our eating with “low-fat” and processed foods is what gets us into trouble. Instead, “Don’t eat anything your great-grandmother wouldn’t recognize as food.” “Sweeten and salt your food yourself.” “Treat treats as treats.” Pollan offers sixty-four rules such as these to guide our choices, but it is truly as easy as 1-2-3: “Eat food. Not too much. Mostly plants.” Rules to live by.
