The purpose of this study was to evaluate the nutrient intake, diversity and prevalence of diseases according to noodle consumption using data from the Korean National Health and Nutrition Examination Survey (KNHANES) of 2010. Korean adults (>20) were classified into two groups, noodle group (NG) and non-noodle group (NNG). NG was found to have higher intakes of protein, calcium, iron, sodium, potassium, and niacin. The DVS and DDS according to noodle consumption were found to be 21.76 and 3.51 for NG, and 18.56 and 3.40 for NNG, this result was thought to show that the diet of NG was more satisfactory than that of NNG in terms of dietary diversity. In the bone mass of entire subjects, NG showed higher figures in the femoral neck and lumbar spine than NNG. For bone mineral density, NG exhibited higher figures in the femoral neck, and for T-scores, the values of NG was significantly higher in the femoral neck than those of NNG. However, the prevalence of osteoporosis of NG and NNG was 11.6% and 9.5%. The prevalence of osteopenia of NG and NNG was 43.0% and 51.7%. Thus, these results showed that overall bone health of NG was better than that of NNG. Dietary balance and quality were also more satisfactory in NG. These results showed that noodle consumption may have an impact on the prevalence of chronic diseases.
