The purpose of this research was to examine the dietary quality and food group intakes of Korean elderly according to chewing ability using data from the Korea National Health and Examination Survey 2013 (KNHANES). Through a complex sampling design, all data was analyzed using a general linear analysis at p<0.05 after adjusting for age and gender. The dietary quality was assessed using the nutrient adequacy ratio (NAR), KDRI (Recommended Nutrient Intake(RNI) or Adequate Intake(AI)) and food group intakes were assessed according to chewing ability for 1134 elderly. Among subjects aged 65 years and over, 48.1% of elderly people were classified as the chewing difficulty group (CD). The CD group had lower nutrients and food group intakes than those with no difficulty in chewing group (Normal group). Specifically, the CD group consumed less fruits (p<0.01), vegetables (p<0.01) and animal oil (p<0.05). In addition, except for the vitamin A intake, the percentage of RNI or Al and the NAR of all nutrients in CD group were significantly lower (p<0.001–0.03). The intake of calcium was below the KDRI in all subjects, and the intake of vitamin C, vitamin B 2 and potassium were below the KDRI in CD group. These results indicate that the dietary intakes of Korean elderly is influenced by chewing ability, showing lower food group intakes and nutrient intakes overall. Among CD group, the CD group seems to need specific nutritional intervention.
