Recent research has already described an association between yogurt consumption and a better diet quality and a healthier metabolic profile, but not for children. This is the main focus of the study conducted by the University of Iowa, based on data of National Health and Nutrition Examination Survey (NHANES) among 5124 children (2-18 years) between 2003 and 2006 in the United States. The nutritional quality of the diet was assessed by using the Healthy Eating Index 2005 (HEI-2005), and metabolic profiles were obtained from the NHANES laboratory data.
Minimum one serving of yogurt a week
It was found that only 33.1 % of children consumed yogurt at least once per week (frequent consumers). The researchers found that these frequent consumers of yogurt demonstrated a better diet quality, a lower fasting insulin level, a lower insulin resistance and a higher index of insulin sensitivity compared to the non-frequent users. Frequent consumers had also a higher HEI-2005 total score. However, yogurt consumption was not associated with body weight, fasting glucose, serum lipid profiles, C-reactive protein, and blood pressures.
