The average American supermarket now carries 48,750 items, according to the Food Marketing Institute, more than five times the number in 1975. Britain’s Tesco stocks 91 different shampoos, 93 varieties of toothpaste and 115 of household cleaner. Carrefour’s hypermarket in the Paris suburb of Montesson, a hangar-like place filled with everything from mountain bikes to foie gras, is so vast that staff circulate on rollerblades.
