Literature suggests that increased duration of residence in the US causes Mexican-Americans to adopt a more “Western” diet, which has been associated with weight gain and elevated risk of chronic disease. Northeastern University researchers conducted a study to determine the effect of duration of residence and nativity in the US on the diet patterns of Mexican-Americans. Using the Food Frequency Questionnaire data from 2003-2004 and 2005-2006 National Health and Nutrition Examination Survey (NHANES), the study compared the healthfulness of the diet patterns of US born and Mexican born Mexican-Americans. It concluded that Mexican Americans generally do not adhere to healthy dietary practices and have dietary patterns that are associated with higher mean intakes of fat, carbohydrates and sugars. This was especially true for US born Mexican Americans.
