We examined the effects of 5 g red pepper powder in soup preload given at breakfast on food intake, blood pressure, body core temperature, hunger, fullness and thirst scores in 29 female collage students. All subjects received two kind of soup preloads in random order. After ingesting a soup, subjects ate other food items as a breakfast ad libitum. Two soups were of the same composition and volume but differed only in 5 g red pepper. So one soup designated as "beef-vegetable" and the other soup designated as "red pepper". Red pepper soup consumption significantly enhanced energy and macronutrient intake by 17%. The hunger scores after test meals were inversely correlated with energy and nutrient intake in beef-vegetable meal. However, the postprandial hunger scores were not correlated with energy and nutrient intakes in red pepper meal. The fullness scores at 90 min after the red pepper meal were inversely correlated with energy and nutrient intake whereas the fullness scores after beef-vegetable meal were not correlated with energy and nutrient intake. These results suggest that hot red pepper ingestion may desensitize some gastrointestinal vagal afferents and disturb feeling of hunger and fullness. The postprandial changes of body temperatures in red pepper meal were higher for a longer time in comparison with those in beef-vegetable meal. For the red pepper meal there frequently were higher correlations between blood pressures and anthropometric measurements, compared to those in beef-vegetable meal. These results might be explained partly by the enhancing effects of capsaicin on thermogenesis and sympathetic nervous system activity. It is concluded that the ingestion of spicy soup with red pepper can increase appetite, energy and nutrient intakes in Korean females, and this effect might be related to disturbed feeling of hunger and fullness.hunger and fullness.

This study investigates the relationship of smoking on daily intake of nutrients and snacks in the Chungnam and Daejeon high school students. Up to date scientific nutrition education and counseling programs in the regular school system is needed for a professional nutrition education teacher. The primary objective of this study was to provide useful information to nutrition education teachers. A survey was conducted with 400 high school students in the Chungnam and Daejeon areas. 381 out of 400 questionnaires were analyzed with SPSS 12.0K. The subjects were composed of 49.8% male, 50.1% female and 40.9% regular high school students, 59.1% business high school students and smokers 43.1%, non-smokers 56.9%. 43.4% of smokers had been smoking since middle school. On analysis of daily nutrient intakes, 16 out of 19 nutrients except animal calcium, Vitamin A and Vitamin C were much more consumed by the smoking group than the non-smoking group non-significantly. Especially vegetable fat and Vitamin E were higher in the smoking group than the non-smoking group (p<0.05). The intake ratio of carbohydrates: protein: fat was similar in the two groups (smoking group 55:15:29, nonsmoking group 56:15:28). Intakes of Vitamin B1 and potassium in comparison with the Korean dietary reference intakes(KDRI) were under 50% in both groups. However, sodium was taken over 200% compared to KDRI in both groups. Intakes of Vitamin C in the smoking group were as low as 76.5% in comparison to KDRI. Smokers need to increase the intakes of Vitamin C considering that smokers need to intake Vitamin C two times than non-smokers. Nutrient intakes from snacks in the smoking group were higher than the non-smoking group. Nutrients that originated from snacks which took over 20% among daily nutrient intakes were 12 nutrients(energy, fat, carbohydrate, calcium, P, Fe, K, Vitamin $B_1$, Vitamin $B_2$, Vitamin C, Vitamin E, dietary fiber) in the smoking group compared to 7 nutrients(energy, vegetable protein, fat, carbohydrate, calcium, Vitamin $B_2$, Vitamin C) in the non-smoking group. The smoking group was significantly paying more money for snacks each month than the non-smoking group was(p<0.01). Periods of consumption were irregular in the smoking group(p<0.05) and the smoking group was used to taking snacks in the morning compared to the non-smoking group. The smoking group preferred sweets and high calorie food over other snacks in comparison of the non-smoking group. The nonsmoking group had better eating habits than the smoking group.

Children's exposure to various vegetables has been associated with higher preferences and intake of vegetables. Attractive names have been reported to increase children's vegetable intake in school lunches. This study hypothesized that the number of vegetables identified correctly may be used as a measure of exposure to vegetables. The survey was administered to students (n=368) at an elementary school located in Gyeonggi-do to determine the association of number of vegetables identified correctly with factors regarding vegetable intakes and effects of descriptive menu names on consumption intentions in school lunches. Students were asked to identify the correct names for nine vegetables and rate their desire to eat six vegetable dishes labeled with general names and two different descriptive names. Descriptive menu names did not consistently increase subjects' desire to eat vegetables compared to general menu labels. Children who ate two vegetable dishes and more per meal tended to identify the names of more vegetables than those who ate less, without reaching statistical significance (P=0.057). Moreover, 5th graders who answered that they ate more than two vegetable dishes each meal had significantly higher scores in identifying vegetable names than those who did rarely (P<0.05). There was no significant association between the number of correctly identified vegetable names and children's vegetable preferences and frequency of being served vegetable dishes. Mother's vegetable preference showed a significant positive association with vegetable preferences of children (r=0.147, P<0.01) and fathers (r=0.340, P<0.01) as well as the number of correctly identified vegetables by children (r=0.183, P<0.01). The results of this study cannot support the advantage of descriptive menu labels over general menu labels. However, it suggests that the number of correctly identified vegetable names could serve as a measure of children's exposure to vegetables associated with factors regarding vegetable intake.

This study was conducted to examine nutrient intake status and iron food sources by dietary iron density of high school girls in Seoul. The subjects of 226 girls were divided into High group (${\geq}$ 6 mg/1,000 kcal, N=115) and Low group (< 6 mg/1,000 kcal, N=111) by dietary iron density. The nutrient intake data obtained by 24-hour recall method were analyzed by Can Pro 3.0 software. Mean age of all subjects was 16.4 years old, heights and weights of High group and Low group were 164.5 cm, 53.4 kg and 161.7 cm, 51.7 kg, respectively. The body mass index (BMI) of High group and Low group was 20.5 kg/m$^2$ and 19.8 kg/m$^2$, respectively. Most nutrient intakes except energy and lipid intakes of High group were higher than those of Low group. High group showed significantly higher intakes of total iron, vegetable iron and animal iron than Low group. Ca and folate intakes of High group were under 75% of the recommended intake (RI) and Ca, iron, folate and vitamin C intakes of Low group were under 65% of RI. The percentage of subjects who consumed iron less than estimated average requirements (EAR) were 40.0% in High group and 77.5% in Low group. Total food intakes of High group showed higher than that of Low group. Total animal food intakes were significantly higher and total vegetable food intakes were significantly lower in Low group than those of High group. Iron intake from meats, fishes, shell fishes and seasonings were significantly higher in High group than Low group. Iron intake from milk and dairy products were significantly lower in High group than Low group. Major food sources of iron were rice, bean curd, pork, and egg in order among both groups.

This study conducted to assess the effectiveness of nutrition education program for elderly females with various diseases. Forty subjects(hypertension ; 20, diabetes ; 12, hyperlipidemia ; 8) out of 56 completed the 7 weeks nutrition education program. The nutrition education program was based for healthy food habits and dietary guidelines for each specific disease. It also included practicing individualized menu planning and exercising program. Energy, calcium, iron, vitamin A and ash intakes significantly increased in the hypertension group. total sodium intake did not decrease, however sodium intake per kcal decreased significantly(p〈0.05). Elderly with diabetes did not show any changes in dietary intakes. Dietary protein, plant fat, ash, and sodium intakes were significantly elevated(p〈0.05), but cholesterol intakes significantly decreased(p〈0.05) in the hyperlipidemic group. Elderly with hypertension agreed strongly with changes of food habits such as increasing milk intake, and decreasing Kimchi, soup, pickles and salty food, and table salt intakes after nutrition education. Diabetic elderly showed significantly improved food habit scores in decreasing white rice intake, sugar intake and increasing sea-weed consumption, vegetable consumption and exercise. Hyperlipidemic elderly did not show much improvement in food habit scores except in biochemical indices. However, mean serum glucose and atherogenic index decreased in the diabetic and hyperlipidemic groups after education, respectively.

This study was conducted to examine food and nutrient intakes of weekday and weekend with 329 high school boys residing in Seoul using the 3-day food record. Frequency for breakfast skipping was the highest as compared with lunch and dinner skipping. Frequencies for breakfast and lunch skipping were significantly higher in weekend than weekday (p<0.05). The daily average food, vegetable food and animal food intakes were 1,327.6 g, 800.5 g, and 425.8 g, respectively. Total food and vegetable food intakes of weekday were significantly higher than weekend(p<0.05). The dietary variety score(DVS) was 20.5 in daily average, 23.3 in weekday and 15.1 in weekend, which showed significantly higher in weekday than weekend(p<0.05). The daily averages of energy, protein, fat and carbohydrate intake were 2244.9 kcal, 89 g, 72.6 g, and 311.2 g, respectively. Fat intake was significantly lower and carbohydrate, fiber, phosphate, iron, sodium, potassium, vitamin A, niacin, folate, and vitamin C intakes were significantly higher in weekday than weekend (p<0.05). The percentages of energy intake from carbohydrate, protein, and fat were 55.4%, 15.8%, 28.8% in daily average, 56.8%, 15.8%, 27.4% in weekday and 53.6%, 15.8%, 30.7% in weekend, respectively. The percentages of energy intake from carbohydrate in weekday and weekend were below 60%, and that from fat was above 27% in weekday and weekend. Carbohydrate intake was significantly higher and fat intake was significantly lower in weekday than weekend(p<0.05). Energy intakes of daily average, weekday and weekend were above 83% as compared with estimated energy requirement(EER). Intakes of dietary fiber, calcium, potassium, vitamin C, riboflavin and folate were below 75% as compared with adequate intake(AI) or recommended intake(RI). Mean adequacy ratios(MAR), an index of overall dietary quality were 0.78 in daily average, 0.80 in weekday and 0.75 in weekend. MAR of weekend showed significantly lower than weekday(p<0.05). This study revealed that the overall nutrient intake status was worse in weekend than weekday among high school boys.

Consumption of vegetables and fruits is associated with a reduced risk of stroke, but it is unclear whether their protective effects are due to antioxidant vitamins or folate and metabolically related B vitamins. The purpose of the study was to test the hypothesis that intake of fruits and vegetables, which are major sources of antioxidant and vitamin B complex vitamins, reduces the risk of stroke. Cases consisted of patients diagnosed with first event of stroke (n = 69). Controls (n = 69) were age-, sex-, and body mass index-matched to cases. Multivariable-adjusted regression analysis showed that subjects who ate four to six servings of vegetable per day had a 32% reduction in the risk of stroke, and those with more than six servings per day had a reduction of 69% after adjusting for age, sex, BMI, and family history of stroke. Intakes of total fat, plant fat, calcium, potassium, vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, niacin, and folate were significantly and negatively associated with the risk of stroke. Although the trend was not significant, stroke risk was reduced in the second quartile (1.21-2.66 servings per week) of fish intake. However, intake of fruits (average daily intake of 1.0 serving) and antioxidant vitamins such as carotene, vitamin C, and vitamin E was not associated with the risk of stroke. In conclusion, our observational study suggests that intake of fat and vegetables, rich sources of vitamin B complex, calcium, and potassium may protect against stroke.

BACKGROUND/OBJECTIVES: Serum ferritin levels are significantly increased after menopause and greatly affect women's health. The aim of this study was to investigate the dietary and non-dietary factors associated with high ferritin levels in postmenopausal women. SUBJECTS/METHODS: Among adult women in 2010-2012, qualified postmenopausal women (n = 3880) were separated into quartiles of serum ferritin. The variable differences among the quartiles of ferritin were determined using either procsurvey chi-square test (${\chi}^2$-test) among categorical variables, or GLM (Generalized Linear Model) among continuous variables. The odds ratio for high ferritin in relation to dietary factors was also determined using procsurvery logistic analysis. RESULTS: Age, obesity, drinking habit, and blood glucose levels were found to be significant indicators of high serum ferritin level after adjusting for all confounding factors. Among the food groups, grain, milk, vegetable, and seaweed intakes were significantly associated with high ferritin levels, but after adjusting for all confounding factors, only grains and vegetables remained significant factors. Among the nutrient groups, calcium, vitamin A, and vitamin C intake were significant factors, but after adjustment, none of the nutrient groups analyzed were associated with a high risk of ferritin. CONCLUSION: Age, obesity, drinking habit, and glucose levels, as well as inadequate intakes of grains and vegetables, were found to be significantly associated with high serum ferritin levels in postmenopausal Korean women.

The number of school lunch-supported children who belong to low-income families has been rapidly increased in Korea. This study was aimed at evaluation of nutritional status of school lunch-supported elementary school children. One hundred school lunch-supported children and 119 non-supported children of fourth to sixth year class in 3 elementary schools in Gyeongbuk rural area were selected, and surveys were conducted twice, i.e., once during school term and once during summer vacation in 2006. Food consumption survey during school term was carried out through an interview by dieticians at school-lunch time using a 24-hour recall method, and the survey during summer vacation conducted by recording food intakes for three days by children. Nutrient intakes were calculated using CAN-Pro 3.0 program. School lunch-supported children showed higher rate of skipping breakfast and rather irregular meal time as compared to non-supported students. Eating alone was more frequent in school lunch-supported children than in nonsupported children. The average nutrient intakes and nutrient adequacy ratios were lower in supported children than in non-supported children. During term, percentages of nutrient intakes provided by school-lunch were higher in supported children than in non-supported children. Intakes of energy nutrients were within acceptable macronutrient distribution ranges, but proportion of carbohydrate intake increased during vacation. Analysis of patterns of food intakes based on major food groups (dairy, meat, grain, fruit, vegetable) indicated that meals during term were more balanced as compared to meals during vacation. In conclusion, food behaviors and nutrient intakes of school lunchsupported children were inferior to those of non-supported children during term and during summer vacation. They were provided with more nutrient intakes from school lunch during term as compared to non-supported children. Therefore, it is necessary not only to keep meal support program during vacation but also to provide a proper nutrition education as a part of school lunch program to improve nutritional status and food behaviors of school lunch-supported children.

본 연구는 2007~2012년 국민건강영양조사 자료를 이용하여 30세 이상 제2형 당뇨병 여성 환자의 과일류 및 생선류 등의 식품섭취량과 심혈관질환 위험인자와의 관련성을 분석하였다. T2DM군이 NFG군에 비해 과일류 및 생선류의 섭취량이 유의적으로 낮았고 이들의 섭취량이 증가할수록 고중성지방혈증의 위험성이 유의적으로 감소하는 것으로 나타났다. 또한, 과일류와 생선류 섭취량은 각각 중앙값 이상으로 많이 섭취한 군 (FF3)이 각각 중앙값 이하로 섭취한 군 (FF1)에의 비해 TG 농도가 높을 위험이 유의적으로 낮았다. 이러한 결과는 과일류에 김치를 제외한 채소류, 버섯류, 해조류의 섭취량을 포함시켜 분석했을 때에도 같은 결과를 나타내었다. 따라서, 한국인 제2형 당뇨병여성 환자의 과일류 및 생선류의 섭취가 심혈관질환에 긍적적인 영향을 미치는 것으로 보이며, 과일류나 생선류 중 어느 한 종류만 많이 섭취하기보다는 두 종류를 모두 적절히 섭취하는 것이 심혈관 질환 위험성을 낮추는데 효과적일 것으로 사료된다.
