Diabetic patients need nutritional education more than those suffering from other diseases because of the necessity of controlling blood glucose levels with dietary treatment. The purpose of this study was to find out the effectiveness of nutrition education on diabetes control and antioxidant status, both of which are related to diabetic complications. Thirty (15 males and 15 females) type 2 diabetes mellitus patients aged $66.7{\pm}8.8$ years participated in a 4-week nutrition education program. Nutrient intakes, blood glucose level, antioxidant status, and DNA damage were evaluated before, immediately after, and three months after the education program. Changes in those parameters over time were analyzed using repeated-measures analysis of covariance. Over time, HbA1c (p=0.000), plasma total cholesterol (p=0.002), plasma thiobarbituric acid related substances (TBARS; p=0.000), and leukocyte DNA damage (p=0.000) significantly decreased; plasma retinol (p=0.001), plasma tocopherol (p=0.000), erythrocyte catalase (CAT; p=0.000), and erythrocyte glutathione peroxidase (GPx; p=0.000) significantly increased. In an evaluation of nutrient intakes by Dietary Reference Intakes for Koreans (KDRI), energy (p=0.009), phosphorus (p=0.033), sodium (p=0.001), potassium (p=0.019), zinc (p=0.043), riboflavin (p=0.050), folic acid (p=0.048) and vitamin C (p=0.008) intakes had significant positive changes. In a correlation analysis of the biochemical and nutritional changes resulting from the education program, plasma TBARS were negatively correlated with potassium (r=-0.418, p<0.05), iron (r=-0.443, p<0.05), riboflavin (r=-0.432, p<0.05), and folic acid (r=-0.446, p<0.05) intakes, while plasma retinol was positively correlated with energy (r=0.543, p<0.01), protein (r=0.543, p<0.01), phosphorus (r=0.425, p<0.05), iron (r=0.485, p<0.05), zinc (r=0.570, p<0.01) and niacin (r=0.510, p<0.05) intakes. Erythrocyte CAT was positively correlated with folic acid intake (r=0.605, p<0.01). From these results, we suggest that an improvement in nutrition resulting from a diabetic education program for type 2 diabetes patients led to improvement in their antioxidant status, also possibly reducing complications resulting from diabetes.

To assess the food intake and diet quality of middle school students who live in Kangneung area, a dietary survey using 3-day food record was conducted with 226 subjects. Seventy five percent of total food intake was in the form of plant foods and the rest in the form of animal food. Diet qualify was assessed by food group pattern, dietary diversity score (DDS), and dietary variety score (DVS). When counting the major food groups consumed, 53% of subjects had a DDS of 3 and 35% of subjects had a DDS of 4. When investigating the consumption pattern of the major five food groups, only 10.2% of subjects consumed foods from all five groups. The groups most frequently missed were dairy products (73.0%) and fruits (71.7%). On average, subjects habitually consumed 22.6 different foods daily, with the mean score of diet variety for males (22.1) being significantly lower than for females (22.9). Correlation coefficients between nutrient adequacy ratio (NAR) and DVS ranged from r=0.40 for vitamin B$_1$to r=0.61 for phosphorus. NAR also improved as the number of foods or food groups consumed increased (p<0.001). Associations between the NAR and high level of DVS was more positive than those between the NAR with DDS. When assessing the dietary quality of subjects using DDS and DVS, many people appeared not to have a desirable food intake. Therefore, to lead them to have nutritionally balanced diet, educating students and their parents on nutrients and suggesting guidelines for a desirable diet is considered to be essential so that they can intake from all of major food groups and have various foods in their diet.

The purpose of this study was to compare the mineral and vitamin intake according to the stage of change in fruit and vegetable intake. The subjects consisted of 256 students, 122 males and 134 females, who are fourth, fifth and sixth grade in an elementary school located in Yeongi-Gun, Chungnam province. The dietary intake wasexamined by 24 hr dietary recall for 1 day and by food record for 2 days from April 19 to May 01, 2007. Stage of change of intake of fruits and vegetables of the students was categorized into three groups: precontemplation, contemplation and preparation, and action. The subjects at the stage of action took kimchi and vegetables more frequently, and also took more vitamin C as well. But the subjects at other two stages did not show any difference in the intake of any food group and nutrients. Percentage of the male subjects who took less than EAR did not show any significant difference by stage of change in all the nutrients. However, there was gradual decrease in the percentage of female taking less than EAR of vitamin C and vitamin B2. The result concludes that vitamin C intake significantly increase gradually as the stages of behavioral change of fruit and vegetable intake proceed although almost all vitamins and minerals tended to increase.

심혈관계질환의 예방과 영양교육의 기초자료를 제공하기 위하여 성인 남녀를 대상으로 규칙적인 운동 습관과 음주, 흡연, 폐경, 비만 여부에 따라 신체계측치와 콜레스테롤, 중성지방, LDL-cholesterol, LDL-cholesterol 등의 혈청지질 및 영양소 섭취량을 비교 조사한 결과는 다음과 같다. 1)체중이나 신장, 비만 정도 및 WHR 등 신체계측지수는 음주나 흡연 여부에 따른 차이가 없었으나, 혈청 중성지방 농도를 유의적으로 상승시켰다. 2)음주군은 비음주군에 비하여 단백질의 열량비율(% RDA)이 유의적으로 높았으며(p<0.05), 흡연군은 비타민 A와 나이아신, 비타민 B6, 엽산, 비타민 C, 비타민 E의 섭취량에 있어서 비흡연자들보다 낮은 경향을 보였다. 3)운동에 의한 혈청지질 농도에는 뚜렷한 차이가 없었으나, 남성들의 경우 현재의 체중과 PIBW, Quetlet index, 엉덩이둘레가 비운동자들보다 많은 것으로 나타났다. 영양소 섭취량에 있어서 남성의 경우 운동군이 비운동군에 비해 콜레스테롤과 나이아신 및 인을 더 섭취하고 있었으며, 당질의 섭취비율은 유의적으로 더 낮았다(p<0.05). 여성의 경우에는 불포화지방에 유의적 차이를 보여 비운동군의 불포화지방 섭취량이 더 많았다(p<0.05). 4)폐경한 여성의 경우 폐경 전 여성에 비하여 신장은 더 작고 WHR은 더 높았다. 폐경 이후 estrogen 분비의 변화로 인하여 혈중 지질 성분 중에서는 cholesterol이 198.4$\pm$36.3mg/dl, LDL이 119.5$\pm$34.9mg/dl로 폐경 전의 수치보다 유의적으로 높았다(p<0.01). 5)비만 여부는 남자의 경우 콜레스테롤 농도에(p<0.01)), 여자의 경우 중성지방 농도(p<0.01)에 대해 의미있는 설명력을 보이는 변수로 작용하고 있었다. 그러나 식이 섭취상태와의 관련성은 나타나지 않았다. 이상에서 생활습관이 신체계측치 및 혈중 지질 농도와 일부 상관을 보이는 것을 알 수 있었으며, 건강위험 요인도 관찰할 수 있었다. 고지혈증은 심혈관계질환의 주요한 위험 인자로 알려져 있으며, 그 유발 요인에는 여러 환경적인 요인과 식이 요인이 있다. 또한 생활습관은 영양소의 섭취량에도 영향을준다. 이처럼 식이 요인과 생활습관은 단독 혹은 상호 영향을 주게 되므로 고지혈증 및 심혈관계질환을 개선하려면 식사요법과 생활습관 교정을 병행하여야 한다. 고지혈증의 원인 중의 하나로 지적되고 있는 음주와 흡연은 상호 유도작용이 있으므로 금연이나 절주를 하고자 할 경우 두가지를 동시에 자제해야 효과적일 것으로 생각된다. 폐경후 여성들에게 발생 빈도가 높은 심혈관질환의 위험요인인 고지혈증을 예방하고자 하는 노력은 폐경후 여성들의 삶의 질적 향상을 위해서도 매우 중요하다. 또한 균형식 섭취와 운동을 통해 혈중 지질 수준을 건강하게 유지하고, 비만으로의 이행을 방지함으로써 심혈관계질환을 예방하도록 하여야겠다.

Folate, a water-soluble vitamin, acts as a coenzyme for one-carbon metabolism in nucleic acid synthesis and amino acid metabolism. Adequate folate nutritional status during the periconceptional period is known to prevent neural tube defects. In addition, insufficient folate intake is associated with various conditions, such as anemia, hyperhomocysteinemia, cardiovascular disease, cancer, cognitive impairment, and depression. This review discusses the rationale for the revision of the 2020 Korean dietary reference intakes for folate, and suggestions for future revisions. Based on the changes in the standard body weight in 2020, the adequate intake (AI) for infants (5-11 months) and the estimated average requirements (EARs) for 15-18 years of age were revised, but there were no changes in the recommended nutrient intakes (RNIs) and tolerable upper intake levels (ULs) for all age groups. Mean folate intake did not reach RNI in most age groups and was particularly low in women aged 15-29 years, according to the results of the 2016-2018 Korea National Health and Nutrition Examination Survey (KNHANES). The percentages of folate intake to RNI were lower than 60% in pregnant and lactating women, but serum folate concentrations were higher than those in other age groups, presumably due to the use of supplements. Therefore, total folate intake, from both food and supplements, should be evaluated. In addition, the database of folate in raw, cooked, and fortified foods should be further expanded to accurately assess the folate intake of Koreans. Determination of the concentrations of erythrocyte folate and plasma homocysteine as well as serum folate is recommended, and quality control of the analysis is critical.

The study examined the relationship among metal health, metabolic syndrome and nutrient acceptance according to gender. Implemented until 2010-2012, the 5th Korean National Health and Nutrition Examination Survey, as an original document, was used for the study. The target was problem drinkers with more than 12 points under AUDIT. Regarding mental health, it was classified into stress, depression and suicidal impulse. Metabolic syndrome was defined when three causes of BMI, waist circumference, FBS, HDL and BP were out of the normal range. The nutrient intake was obtained to confirm the energy intake of nine non-nutrients (Nutrient adequacy ratio: NAR) and the proper intake of the average non-nutrient (Mean adequacy ratio: MAR). These variables were analyzed by frequency, cross analysis and multiple regression analysis through SPSS18.0. In the general features, there was a significant difference according to age, occupation and marital status. In mental health, stress, depression and suicidal impulse were examined. Metabolic syndrome was dependant on FBS, HDL and BP. The nutrient acceptance depended on calcium, vitamin A, thiamine, riboflavin, niacin, vitamin C, and MAR. Logistic regression analysis performed on the variables showed significant differences. Stress, depression, and thoughts of suicide was significantly higher in men aged 19-29 years, and women aged 30-49 years. In the case of the male, those who employed have metabolic syndrome more than those who unemployed. In terms of female, those who were belonged into the middle - low economic level have undergone with metabolic syndrome. In the part of a Mean adequacy ratio(MAR), the male who unmarried, employed, were in the middle low economic levelwere higher. In the case of the female, it was higher for those who were in the middle - low economic level. Overall, an effective way of planning the solution regarding mental health, metabolic syndrome and nutrient intake can be found by considering these features.

Purpose: Concerns about accelerated aging are regularly being discussed. This study analyzed the dietary status and nutritional intake of college students who are about to enter their 30s and 40s. We further suggest ways to eat healthily. Methods: Totally, 67 students attending Daegu Catholic University were provided with a three-day meal record and analyzed. Results: The average demographics of the subjects were as follows: age 23.2 ± 2.0 years, height 165.1 ± 9.0 cm, weight 65.4 ± 13.6 kg, and BMI 23.5 ± 3.9 kg/m². Overall, 76.3% of the subjects skipped breakfast. The food intake evaluation according to the food group intake pattern and the recommended number of servings determined that 38.3% of the subjects did not consume fruits and dairy products (GMVFDS = 111001), and both men and women lacked all food groups. Analysis of the nutrient intake state revealed lesser nutrient intake than the estimated energy need. Evaluation of the %RDA found that consumption of phosphorus was above the recommended amount, whereas all other nutrients were below the recommended amount. Men had a higher intake rate of phosphorus (p < 0.01), iron (p < 0.001), and sodium (p < 0.05) than women, whereas the intake rate of dietary fiber was higher in women (p < 0.05). Evaluation of the food intake by 22 food categories revealed that intake of regular grains was more in men than in women (p < 0.05) whereas women consumed significantly more mixed grains (p< 0.01). In protein foods, men consumed more meat (p < 0.01), while women consumed more eggs (p < 0.05) and beans (p < 0.05). Evaluating the fruit intake, juices were more frequently consumed by men than by women (p < 0.05). No differences were obtained in food intake and nutrient intake status according to obesity. Conclusion: Based on these results, there is an urgent requirement for attention and support for university cafeterias in order to induce changes in the eating habits of college students. Among other initiatives, this can be achieved by providing diet improvement programs and menus that consider food preferences.
