What to Eat

How do we choose what to eat? Buffeted by health claims--should we, for example, restrict our intake of carbs or fats or both? Is organic food better for us?--we become confused and tune out. In supermarkets we buy semi-consciously, unaware that our choices are carefully orchestrated by sophisticated marketing strategies concerned only with the bottom line. That we should confront such persuasion is the major point made by nutritionist-consumer advocate Marion Nestle in her extraordinary What to Eat, an aisle-by-aisle guide to supermarket buying and thus an anatomy of American food business.
