The purpose of this study was to compare the quantitative and qualitative assessment of dietary intake between patients with metabolic syndrome (MetS) and healthy subjects and to investigate dietary factors related to MetS. Anthropometric measurements, blood analysis, and dietary intake as assessed by 24-hour recall were conducted in MetS patients (n=15) and healthy subjects (n=25). In order to assess the quantity and quality of dietary intake, daily nutrient intake, nutrient density, nutrient intake to dietary reference intake (DRI), nutrient adequacy ratio (NAR), food intake, dietary diversity score (DDS), and dietary variety score (DVS) were analyzed. The statistical differences between MetS patients and controls were analyzed using the SAS software program. Daily energy intake and food intake were not significantly different between the two groups (2,154.3 kcal vs. 1,872.9 kcal; 1,280.0 g vs. 1,261.6 g). There were also no significant differences in daily nutrient intake, nutrient intake ratio to DRI, NAR, or DVS between the MetS group and the control group. However, daily intake of eggs and milk in MetS patients was significantly lower than in the control group (9.0 g/day vs. 30.3 g/day, p<0.05; 0 g/day vs. 49.7 g/day, p<0.05). These results indicate that low intake of eggs and dairy products may be related to the development of MetS.

This study was carried out to estimate the dally intake of lead and the relationship among dietary In take, serum level, and urinary excretion of calcium In 30 healthy adults living In rural area of Korea (12 males and 18 females). Analyses for the nutritional status of the subjects were performed by 3-day dietary intake record, duplicated diet collection, 24-hour urine collection, and venous blood sampling. The results were as follows The mean daily intake of energy was 2,176.3kcal and 1,613.9kcal in males and (tamales of 20∼49years, and 1,914.8kcal and 1,517.9kcal in males and females of 50∼59years, respectively The ratio of carbohydrate : fat : protein was 73.4:13.6:13.0 in males and 76.4:10.3:13.3 In females. The mean daily intake of lead was 277.2Pg in males and 192.0ug in females. The mean daily intake, serum level, and urinary excretion of calcium were 491.1mg, 8.9mg/dl, and 80.7mg in males and 426.7mg, 8.8mg /dl, and 80.3mg in females, respectively. No significant correlation was found between the daily lead intake and the dietary intake, serum level, and urinary excretion of calcium. It was concluded that the daily lead intake was lower than the acceptable daily lead intake of FAO/WHO but a little higher than that of other investigations. And the daily lead intake was not level that relate to calcium status seriously.

The purpose of this study was to estimate the daily manganese (Mn) intake of Korean children. This study was done using a three-day dietary intake survey of 257 Korean children (boys 123; girls 134). The Mn intake values were calculated based on a database that provides the Mn content of the frequently consumed Korean foods, alongside the food composition table provided by the Korean National Rural Living Science Institute. The average age, height, weight and body mass index of our subjects were 11.9 years, 155.4 cm, 48.9 kg and 20.2 kg/$m^2$ in boys and 11.9 years, 154.1 cm, 43.5 kg and 18.3 kg/$m^2$ in girls. The average daily energy intakes were 2,249.2 kcal in boys and 2,044.5 kcal in girls. Boys consumed significantly more Mn than girls, based on intake estimates of $4,585.3{\mu}g$ (117.6% of adequate intake) and $4,029.3{\mu}g$ (117.1% of adequate intake), respectively (P < 0.001). Boys had a Mn intake of $2,041.1{\mu}g$ per 1,000 kcal of energy consumption, whereas for girls this was at $1,983.9{\mu}g$ per 1,000 kcal. Neither group exceeded the tolerable upper intake level for Mn. The major food groups which contributed to Mn intake in our subjects were cereals (50.8%), vegetables (21.0%), seasonings (8.9%), and pulses (7.7%). Notably, boys derived a higher Mn intake through cereals and vegetable than did girls (P < 0.001, P < 0.05). The key food sources of Mn, in descending order, were rice, soybean curd, kimchi, black rice and cereals. We propose that the results of our study may be used as a basis for follow-up studies that examine the Mn intake of children.

Objectives: The aim of this study is to examine the possible changes over the past ten years in the estimated daily dietary lead intake (Pb-D) stemming from the variation of daily intake amounts for each food group. The following factors were considered; 1. time trends in Pb-D as the estimated values, 2. the time trend in Pb-D by food groups 3. the most influential food groups for dietary Pb intake. Methods: Estimated Pb-D was drawn from food consumption according to food groups reported in the Korean National Health and Nutrition Survey and the lead contents of each food group as reported in 23 prior publications. Results: The estimated Pb-D in a 2009 survey was 40.8 ${\mu}g/day$, of which 22.5 ${\mu}g/day$ (55.1%) was of plant origin and 18.3 ${\mu}g/day$ (44.9%) was of animal origin. Meats and poultry, fish and shellfish among foods of animal origin and beverages of plant origin had the largest contribution in Pb-D among the food groups. Conclusion: Over past ten years, daily lead intakes have slightly increased among men. Otherwise, no clear variation is apparent among women.

The daily caffeine intake from elementary school children's favorite foods was surveyed and evaluated. Children may respond to caffeine differently from adults because they have different physiological makeup and are functionally immature. Therefore, caffeine exposure may have more serious consequences for children than for adults, irrespective of sensitivity. Their preference, perception, and intake of caffeine from children's favorite foods were investigated by questionnaire for 355 children. The order of children's preference over foods containing caffeine was ice cream and ices, confectionary, milk and milk products, and soft beverage. The daily caffeine intake of children was estimated to range from 0.16 to 917.28 mg/day, with an average of $36.04\;{\pm}\;82.7$ mg/day and $36.9\;{\pm}\;96.0$ mg/day for boys and girls, respectively. The daily caffeine intake according to body weight was $1.08\;{\pm}\;2.23$ mg/kg and $1.12\;{\pm}\;2.66$ mg/kg for boys and girls, respectively. The percentage of acceptable daily intake (ADI) of caffeine was 43.4% for boys and 44.9% for girls. The sources of caffeine for boys and girls were soft beverage (18.3 mg and 16.1 mg), milk and milk products (8.9 mg and 8.5 mg), ice cream and ices (5.7 mg and 7.3 mg), chocolate (1.6 mg and 3.2 mg), and confectionery (1.6 mg and 1.8 mg).

This study aimed to estimate daily intake of anthocyanins and to identify major sources of anthocyanins in current Korean dietary patterns in order to implement dietary recommendations for the improvement of Korean health. Sixteen foods were selected based on the availability of food intake and reliable anthocyanin content. Food intake data from the Korea National Health and Nutrition Examination Survey 2014 and anthocyanin content data from earlier investigations were used to calculate the consumption of anthocyanins. Anthocyanin contents of 16 foods varied significantly and exhibited a range of 0~4,009 mg/100 g of fresh weight. Daily intake of anthocyanins was estimated to be 3.3 mg to 95.5 mg in Koreans. Of the 16 foods studied, the source contributing most to anthocyanin intake in the Korean population was plums (35.1%), followed by black beans (17.1%) and grapes (15.2%). These results indicate that major foods contributing to anthocyanin consumption in the Korean dietary pattern are fruits and grains.

This study was conducted to investigate the dietary habits and assess the dietary intake of preschool children. Food habit, preference and nutritional supplement status were investigated using a questionnaire answered by the mothers of 453 subjects aged 3 to 6 years old. Also, a dietary intake survey using a 24-hour recall method was performed by mothers of the children. It was found that 81.2% of subjects had milk, dairy products, cookies, fruit and bread between meals once or twice per day. As well, 60.3% of subjects had an unbalanced diet and 20.7% had an overeating habit. Thus, unbalanced diet was a serious problem for many of the subjects. Due to weight controls, digestion problems and allergies, 11.7% of subjects had special dietary consideration. And 26.4% of subjects were using nutritional supplements. From the 24-recall survey, it was found that all nutrient intakes were higher than the Korean RDA except calcium and vitamin A. Nutrient intakes for protein, calcium, phosphorus and vitamin B2 were significantly different by sex, and also increased with age but not significantly. Children received 35% of daily energy, 44% of daily fat and 52% of daily calcium from snacks, so snacks clearly play an important role in dietary intake. The average number of foods consumed per day by subjects was 17.6 and that dishes was 11.0. Most children consumed 4 or 5 food groups per day. In conclusion, the dietary intake of children aged 3 to 6 were deemed adequate judging from nutrient intake and dietary diversity. More attention should be paid to the nutritional value of snacks in this age group.

Previous studies have shown that sodium excretion is positively related to calcium excretion in the urine. As excessive sodium intake is a common nutritional problem in Korea, we intended to investigate associations among sodium intake levels and calcium status, evaluated by 24 hour recall method and urinary excretion, and bone status. We collected dietary information for non-consecutive three days from 139 young adult women 19~29 years. After classifying the subjects into 4 groups based on the dietary sodium levels by daily total sodium intake (mg) and sodium density (sodium intake per 1000 kcal energy intake), we compared the bone status, nutrient intakes, urinary calcium and sodium excretions. The results showed a positive association between total daily sodium intake and intake of other nutrients. However, no significant differences in nutrients intakes were observed among subject groups classified by sodium density levels. There were no significant differences of bone density among groups by total daily sodium intake as well as by sodium density. While total daily sodium intake showed significantly positive relationship with urinary sodium (p < 0.05) and calcium (p < 0.05), sodium density was not related to urinary excretion of calcium and sodium. Our results suggested that promoting balanced meals providing appropriate amounts of energy intake is the essential component of nutrition education for improving calcium status of young Korean women with excessive sodium intake.
