" The diet and lifestyle changes for the Tokelauans who immigrated to New Zealand were abrupt and even more dramatic. Bread and potatoes replaced breadfruit in their diets; meat replaced fish; they hardly ate any coconuts. Sugar consumption skyrocketed, as did physical activity: the men went to work as manual laborers in the forest service or on the railway, and the women got jobs in electrical assembly plants or clothing factories, or they cleaned offices during the evening hours, walking miles to and from work. In both populations, a similar pattern of chronic diseases erupted with the Westernization of the diet. Between the late 1960s and early 1980s, diabetes prevalence shot upward, particularly among the immigrants. By 1982, almost 20 percent of the immigrant women and 11 percent of the immigrant men—one in five and one in nine, respectively—were diabetic. Hypertension, heart disease, and gout also increased significantly, particularly in the migrant population (the migrants were nine times as likely to get gout as those remaining behind on the atolls). Obesity, unsurprisingly, also increased: Both men and women gained, on average, between twenty and thirty pounds. Children, too, got fatter. "
