Secular trends in dietary macronutrient intake in Minneapolis-St, Paul, Minnesota, 1980-1992.
Trends in dietary macronutrient intake were evaluated in population-based surveys conducted in adults aged 25-74 years in 1980-1982, 1985-1987, and 1990-1992 in the seven-county Minneapolis-St. Paul metropolitan area. A 24-hour dietary recall (n = 6,499) was completed by a random 50% sample. The authors obtained energy intake for each macronutrient (protein, carbohydrate, fat, saturated fat, monounsaturated fat, polyunsaturated fat, and alcohol). Tine trends for percentage of total energy were analyzed using a generalized linear mixed model. While energy intake remained stable over time, macronutrient composition changed substantially. In 1980-1982, the caloric distribution for men comprised 15.8% protein, 39.4% fat, 40.9% carbohydrate, and 3.9% alcohol; similar findings were observed in women (15.7% protein, 38.9% fat, 43% carbohydrate, and 2.4% alcohol). From 1980 to 1992, total fat intake decreased 4.7% in men and 4.9% in women (p < 0.001). The decline was greatest for monounsaturated fat, although saturated and polyunsaturated fat intake also fell. During this same period, carbohydrate intake increased 5.7% and 5.8% in men and women, respectively (p < 0.001). Alcohol intake decreased in men and women (p < 0.01), while protein intake remained stable. In summary, the Minneapolis-St. Paul metropolitan area diet shifted substantially during the 1980s toward more carbohydrate and lower fat and alcohol intake.
