Improved diet quality and increased nutrient intakes associated with grape product consumption by U.S. children and adults: National Health and Nutrition Examination Survey 2003 to 2008.

Fruit contributes to dietary nutrient density and consumption of fruit in several forms (whole, dried, or 100% juice) has been reported to be associated with a healthier dietary pattern. The goal of this study was to examine the associations of the consumption of grapes (including fresh grapes, raisins, and 100% grape juice) with diet quality and food group/nutrient intake. A secondary analysis of Natl. Health and Nutrition Examination Survey (NHANES) 2003 to 2008 data was conducted to compare grape consumers (GC) with nongrape consumers (NGC) among children aged 2 to 19 y (n = 9622) and adults 20+ y (n = 12251). GC were defined as those who mentioned the consumption of fresh grapes, raisins, or 100% grape juice during 1 or both 24-h recall interviews. Compared to NGC, GC had higher Healthy Eating Index 2005 (HEI-2005) scores and higher intakes of total and whole fruit along with lower intakes of solid fat, added sugars, and calories from solid fats, alcohol, and added sugars (SoFAAS). Among adults, GC also had higher intakes than NGC of total and dark green/orange vegetables. Among both age groups, GC had higher intake than NGC of several key nutrients including dietary fiber, vitamin A, vitamin C, calcium, magnesium, and potassium. Consumption of grape products is associated with a healthier dietary pattern and higher intake of key nutrients by both children and adults.
