Association of raisin and raisin-containing food consumption with nutrient intake and diet quality in US children: NHANES 2001-2012

Abstract

Background: Raisins are a commonly consumed dried fruit and given their nutrient profile may offer nutritional and health benefits. Objective: To examine the association between consumption of raisins and raisin-containing foods with nutrient intake and dietary quality in children. Methods: National Health and Nutrition Examination Survey (NHANES) data for 2001–2012 in those 2–18 years of age (n = 20,175) were used. Consumers of raisins (n = 154, 51.6% female) and raisin-containing foods (n = 1,993, 52.5% female) were defined as reporting any consumption of raisins and raisin-containing foods, respectively, during the first 24-hr diet recall. Diet quality was assessed using the Healthy Eating Index (HEI)-2010. Regression analyses were conducted comparing consumers and nonconsumers using appropriate sample weights and adjusted for demographic and lifestyle covariates with significance set at p < 0.01. Results: Regarding “nutrients of public health concern/shortfall nutrients” and “nutrients to limit,” raisin consumers had higher intakes of dietary fiber (23%), potassium (16%), magnesium (12%) with lower intakes of added sugars (−19%) than nonconsumers. Similarly, consumers of raisin-containing foods also had higher intakes of dietary fiber (15%), potassium (5%), magnesium (11%), iron (6%), vitamin A (10%), and vitamin E (13%) and lower intake of sodium (−5%). Consumers of raisin and raisin-containing foods had higher intakes of fruits (60%, 16%, respectively), whole fruits (119%, 23%, respectively) and whole grains (44%, 93%, respectively) and had a better diet quality as per higher total HEI 2010 scores (22%, 8%, respectively) than nonconsumers. Conclusion: In conclusion, consumption of raisins or raisin-containing foods was associated with better nutrient intake and diet quality in American children.
