NCT01369173

Brief Summary

The foods eaten daily are considered the "dietary pattern" of a culture or country. The dietary pattern of Mexico is different from that of the United States. To look at the effects of these patterns, participants in this study eat a Mexican menu for three and a half weeks and an American menu for the same length of time. At the beginning and end of each menu period participants provide blood and urine samples which we analyze to compare the effects of each diet. More info at www.ProyectoCOMIDAS.info

Outcome Measures

Primary Outcomes (1)

  • metabolic response measured by blood concentrations of biomarkers

    Participants will have a blood draw at the beginning and end of each intervention arm.

    Change from Baseline at 24 days

Study Arms (2)

Mexican Menu

ACTIVE COMPARATOR

24 days, all foods and drinks provided, menu consists of traditional mexican meals

Other: Mexican or American foods

US diet

ACTIVE COMPARATOR

24 days, all foods and drinks provided, menu consists of foods commonly eaten in contemporary United States

Other: Mexican or American foods

Interventions

Participants will be randomized to an isocaloric Indigenous Mexican or a Western diet for 24 days. All foods and beverages will be prepared by the Human Nutrition Laboratory at the Fred Hutchinson Cancer Research Center. After a 4-week wash-out period, participants will cross over to the other arm and be given the alternate diet for 24 days. Blood and urine specimens will be collected before and after each feeding period to test baseline and post-intervention metabolic response as defined by various inflammatory and cancer susceptibility biomarkers including insulin-like growth factor 1 (IGF1), insulin-like growth factor binding protein 3 (IGFBP3), leptin, adiponectin, interleukin-6 (IL-6), C-reactive protein (CRP) and SAA (serum amyloid-A). DNA extracted from whole blood will be used to test whether a panel of 128 Ancestry Informative Markers (AIMs) is associated with metabolic response to the diets and other phenotypic traits of obesity, which relate to breast cancer risk.
