Summary

Avocados are an excellent source of fiber, potassium, magnesium, and poly- and mono-unsaturated fats. They can be a nutrient dense component of healthful dietary patterns and have the potential to improve the cardiovascular disease (CVD) risk profiles of families in the United States (US). The proposed research plan will focus on the contribution of avocado intake to the reduction in CVD risk of US families, by examining the effects of avocado intake on the overall nutritional status of families. Of particular interest is establishing these effects in ethnic populations such as Hispanics/Latinos. On average, Hispanic/Latinos are at increased risk for metabolic diseases that predispose to CVD. This 6-month cluster randomized trial in Hispanic/Latino Americans aims to accurately determine the impact of avocados on the overall dietary pattern of their families. Future research will extend the results of the current trial to a larger sample of ethnically diverse families in order to evaluate whether sustained changes occur in nutritional, cardiovascular and metabolic health status.

Detailed description

Specific Aim 1: To determine how avocados are incorporated into the family's dietary pattern and impact selected measures of nutritional status: 1. To determine if avocado intake substitutes for, or adds to, other sources of calories in the family diet. 2. To determine if avocado intake helps reduce between-meal snacking of family members. 3. To determine if avocados help families meet US Dietary Guidelines for recommended intake of: poly- and monounsaturated fats; vegetables; fiber; selected nutrients (vitamins C, D and E, Folate, Calcium, Magnesium, potassium, iron); lutein and other carotenoids. Specific aim 2: To determine if increased avocado intake affects cardio-metabolic risk factors to include lipids, glucose, insulin, and HbA1c.
