Diet and Nutrition are important modulators of bone health in men and women. We investigated the associations between frequency of food intake among certain food groups and bone mineral density (BMD) in a large population of Korean adults.
We used the data from Korea National Health and Nutrition Examination Survey during 2008 to 2009. Participants were aged 20 years and over. BMDs were measured at lumbar spine and femoral neck with dual-energy X-ray absorptiometry. Dietary and supplement intakes were assessed by food-frequency questionnaire. We used multiple linear regression analysis to evaluate the relationships between annual food-frequency of each food group and BMD.
After adjustment of multiple covariates, femoral neck and lumbar BMD significantly increased as the frequency of fruit consumption increased in both men and women. Frequency of other carbohydrates consumption was significantly associated with greater femoral neck and lumbar BMD for women. Frequency of milk and dairy product consumption was significantly associated with greater femoral neck BMD in men. Other food groups, however, had no significant associations with BMDs.
Frequent consumption of fruit has a positive association with BMDs in men and women. Milk and dairy products and other carbohydrates also had positive effects on BMD for men and women, respectively.

This study was performed to evaluate the association between food intake frequencies and long-term blood glucose control using glycated hemoglobin (HbA1c) in Korean diabetes.
This study used data collected from the 4th Korea National Health and Nutrition Examination Survey. Patients with diabetes were defined as people who responded "yes" to the question "Are you currently suffering from diabetes?" or in whom serum fasting glucose was 126 mg/dL or more. Using the food frequency questionnaire and HbA1c in surveys, we examined the association between the annual food-frequencies of each food group and long-term blood glucose control.
After adjustment for other covariates, HbA1c decreased significantly as the frequency of the intake of fish increased in each population (P = 0.001 for all, P = 0.043 for men, P = 0.001 for women). The intake of mackerel played an especially important role in the control of diabetes. Among women, HbA1c decreased as the frequency of intake of legumes increased (P = 0.029) and increased as the frequency of intake of staple carbohydrates increased (P = 0.015). On the other hand, any intake of other food groups showed no significant relationship with HbA1c.
Frequent intake of fish in all populations and legumes in woman were associated with good glycemic control in diabetics. Frequent intake of carbohydrates was associated with elevated HbA1c in women.
