Differences in energy, nutrient, and food intakes in a US sample of Mexican-American women and men: findings from the Third National Health and Nutrition Examination Survey, 1988-1994.

As Mexican-American women and men migrate to the United States and/or become more acculturated, their diets may become less healthy, increasing their risk of cardiovascular disease. Data from the Third National Health and Nutrition Examination Survey (1988-1994) were used to compare whether energy, nutrient, and food intakes differed among three groups of Mexican-American women (n = 1,449) and men (n = 1,404) aged 25-64 years: those born in Mexico, those born in the United States whose primary language was Spanish, and those born in the United States whose primary language was English. Percentages of persons who met the national dietary guidelines for fat, fiber, and potassium and the recommended intakes of vitamins and minerals associated with cardiovascular disease were also compared. In general, Mexican Americans born in Mexico consumed significantly less fat and significantly more fiber; vitamins A, C, E, and B6; and folate, calcium, potassium, and magnesium than did those born in the United States, regardless of language spoken. More women and men born in Mexico met the dietary guidelines or recommended nutrient intakes than those born in the United States. The heart-healthy diets of women and men born in Mexico should be encouraged among all Mexican Americans living in the United States, especially given the increasing levels of obesity and diabetes among this rapidly growing group of Americans.
