Form reports of the Korean National Nutrition Survey from 1969 to 1989, trends of nutrients intakes are reported as follows. The amount of energy intakes are decreased gradually. The proportion of energy from cereals to total energy are decreased from 85.9 percent at 1969 to 66.5 percent at 1989. There are increasing trend for the proportion of energy from animal foods to the total energy. The amount of protein intakes are increasing gradually. The ratio of animal protein to the plant protein have been increasing since the survey has been started. The amount of fat intakes are also increasing. The proportion of energy from the fat and protein to total energy had been shown increasing trends. Gradually, the calcium and iron intakes are increasing over the years. But the intakes of calcium is less than the average dietary allowance of subject examine until recently. The intakes of thiamin, showing adequate intake, are almost equal to the average dietary allowance. For the riboflavin, the amount of intakes are increasing from the mid nineteen-eighty. But the intake of riboflavin is less than the average dietary allowance. For the niacin and ascorbic acid, the amount of intakes are showing variations. But the amount of intakes are not inadequate.

To assess the quality of nutrient intake by area of Korean adults, a dietary survey with the 3-day record method was obtained from 324 subjects aged 40 years and older but younger than 70 (52.4 $\pm$ 8.7) living in a rural area (Ansung) and suburban area of a middle-sized city (Ansan). The quality of nutrient intake was assessed by analyzing Nutrient Adequacy Ratio (NAR), Mean Adequacy Ratio (MAR) and Index of Nutritional Quality (INQ). The average daily mean energy intakes were 1,832 ㎉ for Ansung and 1,842 ㎉ for Ansan, respectively. Daily intakes of fat for Ansung and Ansan subjects were 40.9 and 40.3 g, and those for protein were 75.1 and 73.1 g, respectively. The overall calorie: protein: fat ratio (CPF) of energy intake was 63 : 17 : 20. Daily mean intakes of protein, fat, calcium, phosphorus, iron, potassium, carotene, sodium, thiamin, and niacin were significantly higher in Ansung residents than in Ansan subjects (p < .05). The average intakes of energy, calcium, vitamin A were lower than Recommend Dietary Allowance (RDA) in both areas. Note, over 30% of the study subjects had less than 75% of RDA of calcium, vitamin A and riboflavin. The MAR was higher in Ansung than Ansan residents (0.86 and 0.85, respectively; p < .05). INQs were over 1 for most nutrients except calcium (0.87), and that of calcium and phosphorus was each significantly higher in Ansung than Ansan subjects. Based on these results, nutrient intake quality of subjects aged 40 to 69 years living in the surveyed rural area is comparable to that of semi-industrialized suburban area in Korea. Dietary deficiency in all of calcium, vitamin A, and riboflavin, however, was a common problem for both rural and suburban residents.

This study was conducted to investigate both fat-soluble and water-soluble vitamin contents of commercial powdered infant formula for obtaining basic data on infant nutrition. Ten commercial infant formula based on cow's milk were collected and the contents of fat-soluble vitamins (vitamin A, D, E, K) and water-soluble vitamins (vitamin C, thiamin, riboflavin, niacin, $B_6$, folate, $B_{12}$, pantothenic acid, biotin) were compared with Dietary Reference Intakes for Koreans (KDRIs). The overall vitamin contents in 100 g and in 100 kcal of infant formula satisfied the recommended formula regulation (KDRIs) and Codex. In infant formula during 0-5 monthly age, fat-soluble vitamin A, D, E, K could supply 178.6%, 205.3%, 208.4%, 976.3% of adequate daily vitamin intakes, respectively. Water soluble vitamins, vitamin C, thiamin, riboflavin, niacin, $B_6$, folate, $B_{12}$, pantothenic acid, biotin could supply 173.2%, 237.2%, 269.8%, 295.9%, 431.6%, 165.8%, 1186.3%, 203.8%, 408.3% of adequate daily vitamin intakes, respectively. In infant formula during 6-11 monthly age, all vitamins satisfied their adequate daily intakes as well. Vitamin A, D, E, K supplied 199.2%, 262.3%, 220.5%, 626.46% of adequate daily vitamin intakes. Vitamin C, thiamin, riboflavin, niacin, $B_6$, folate, $B_{12}$, pantothenic acid, biotin could supply 179.5%, 210.2%, 264.7%, 241.5%, 206.0%, 166.9%, 699.5%, 247.0%, 475.0% of adequate intake of KDRIs. From this study, evaluation of vitamin contents of commercial infant formula was established, which could strengthen the basic information on infant nutrition.

Purpose: This study examines the effectiveness of personalized goal setting and smartphone-based nutrition counseling among adults in their 20s and 30s. Methods: Nutrition counseling was conducted for a total of 30 adults through a 1:1 chat room of a mobile instant messenger, once a week for 8 weeks. The first week of counseling included a preliminary online questionnaire survey and a dietary intake survey. Based on the results of the preliminary survey, 2 dietary goals were set in the second week and the participants were asked to record their achievements on a daily checklist. From the third week onwards, counselors sent feedback messages based on the checklist and provided information on dietary guidelines in a card news format every week. Post-counseling questionnaires and dietary intake surveys were conducted in the seventh week. Changes in dietary habits during the counseling were reviewed in the eighth week, followed by a questionnaire survey on the evaluation of the counseling process. Results: The nutrition quotient (NQ) scores and self-efficacy scores were significantly higher after nutrition counseling. The NQ scores of consumption frequencies of fruits, milk and dairy products, nuts, fast food, Ramyeon, sweet and greasy baked products, sugarsweetened beverages, the number of vegetable dishes at meals, and breakfast frequency were significantly higher after nutrition counseling. The intake of protein, vitamin A, thiamin, riboflavin, folate, calcium, and iron, and the index of nutritional quality of vitamin A, riboflavin, folate, calcium, and iron were higher after nutrition education. The participants were satisfied with the nutrition counseling program and the provided nutrition information. Conclusion: Personalized goal setting and smartphone-based nutrition counseling were found to be effective in improving the quality of diet and self-efficacy in young adults. Similar results were obtained in both the underweight/normal weight and the overweight/obese groups.

This study investigated anthropometric and biochemical characteristics, nutrient intakes, and bone density of Korean elderly men (over 65 yrs). Data on bone density and anthropometric (height, weight, waist circumference, body mass index and blood pressure) and biochemical (total cholesterol, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, triglyceride and hemoglobin) characteristics, nutrient intakes, and nutrient density were obtained from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES, 2008~2011). Subjects were categorized into smoking and non-smoking groups, and smoking groups were divided into three groups by smoking period (under 20 yrs, 21~40 yrs and over 41 yrs). Serum triglyceride concentrations of the smoking group aged 21~40 yrs were higher than those of other groups (P<0.01), whereas other biochemical factors were not different. Intake ratios of energy, protein, phosphorus and sodium in subjects were over 100% of Dietary Reference Intake for Koreans (KDRI). Nutrient densities according to intakes of thiamin, riboflavin, and niacin per 1,000 kcal were significantly different among the groups (P<0.05). Bone density of subjects decreased according to smoking period (T-score of total femur in non-smoking group -0.3108, and -0.2918, -0.4941, -0.6847 in smoking group, respectively). Ratio of osteoporosis was 38.1% in the non-smoking group and 44.4%, 51.1%, and 64.0% in the smoking group, respectively. The findings of the present study show that smoking may be associated with bone health, higher ratio of osteoporosis, and low nutrient density in elderly men. Therefore, practical and systematic non-smoking programs are required to improve the bone density of elderly men as well as maintain healthy bone levels and desirable lifestyle.

A Survey was conducted to identify patrcis' eating behavior at the buffet styled restaurant during dinner time. The average frequency of taking food was 4.1±0.9 and this was statistically significant by age group. The frequency of taking food after satiety was 1.2±0.8. From the menu, 15 seafood items were the most popular which were chosen more than twice. The average of consumed food items was 24.9±8.9 out of 198. The average seafood items which were chosen by each individual was 5.8, desert items was 4.5, salad items with dressing was 4.2. The total weight of the consumed food was 954±365.1g. Mostly gruel, soup and saled chosen the first time. Alcholic beverages and drinks were chosen also first time. Seafood was chosen the 1.2 times and meat was chosen the first, second, and third time. Rice and soup. bread and noodles were chosen the second and third time. Desert was chosen the third time. The consumption of calories and nutrients were compared with the Korean Recommended Dietary Allowances. The average consumption of calories was 49.6% Korean RDAs, protein 71.4%, vitamin A 65.0%, thiamin 74.3%, riboflavin 71.8%, niacin 89.8%, ascorbic acid 72.7%, iron 68.1%, and calcium 108.3%. In one meal, the data shows over eating. The caloric consumption of desert was 275.5Kcal and seafood was 174.1Kcal. The protein consumption of seafood was 23.5g and meat was 7.5g. According to this research, customers have a lot of good chances to be exposed to the variety of food. This is desirable to correct the food habits with a experience. On the other hand, excessive food consumption is a problem. Therefore we suggest the provision of nutrition information about desirable order of eating a meal and the health problems due to overeating. We expect other research of nutritional evaluation in a meal in the different foodservice systems to be made in the future.

In order to investigate if the employment of housewives may affect the nutritional status of their family members, an analysis was made for the data of 2001 Korea National Health and Nutrition survey. Housewives aged 20 or over were divided into two groups of the working (W, 44.3%) and the non-working (NW, 55.7%), and household income levels were divided into 4 groups of low, middle, high, and high above according to the minimum cost of living in the year of 2001. Nutrient intakes were assessed by using dietary recommended intakes for Koreans of 2005. Working housewives showed similar levels to those of non-working housewives in most nutrients intakes except energy and vitamin C. However their families excluding housewives of W, than those of NW, took less protein, calcium, iron, potassium, vitamin A, thiamin, riboflavin, niacin, and vitamin C when assessed as % of recommended intakes and took more sodium. Such differences were very strong in children and adolescents, and in the middle income households. More % of the families of W than those of NW consumed nutrients below the estimated average requirements. Percents of hypertension classified by both systolic and diastolic blood pressure were higher in adult family members of W than in those of NW. This tendency seemed to be more significant in the family members aged 30 to 49. Both obesity and under-weight rates of school children ($7{\sim}12\;yrs$) in W were higher than those in NW. The above resuIts suggested that employment of housewives could have negative influences on the nutritional status of their family members, especially of their children and in the middle income class.

The estimation of the nutritional requirements at the national or population level has a great difficulty in calculating the cumulative effects of the several variables, i. e. age, sex, weight activity, etc., in order to adapt nutrient requirements to the condition of a country or to a population group. The Joint FAO/WHO Expert Group on nutrient requirements had proposed a simpler model, an average daily per capita nutritional requirements that will enable the different parameters to incorporated in a single calculation table. The average daily per caita nutritional requirements for Korean-1982 calculated by this proposed method are as follows : energy, 2,200 kcal ; protein, 70g : calcium, 0.72g ; iron, 14mg; vitamin A, 1,900 IU ; ascorbic acid, 50mg ; thiamin, 0.9mg ; riboflavin, 1.2mg ; niacin equivalent, 15mg. The average daily per capita nutritional requirements would be used to assess the adequacy of the national dietary intakes and provide basic information for the establishment of national food production and consumption policies and the planning of programmes aiming at an adequate and equitable distribution of food supplies. On a different levels, they would be used widely in the planning of diets for a specific population group, and also provide important reference information for the epidemiology study of nutritional deficiencies.

This study was conducted with 20 female gymnasts to examine the relationship between eating patterns, diet menstrual function and hematological status. According to the baseline data a nutrition counseling and education program was developed and evaluated improved the nutritional status and health of female gymnasts. Mean body weight at the onset of the study was 42.1$\pm$7.0kg and was reduced to 41.8$\pm$6.1kg after the nutrition counseling and education program. The percent of body fat was significantly reduced from 13.9$\pm$3.7% to 13.1$\pm$3.1%(p<0.01) skinfold thickness of subscapular and thighs was reduced significantly(p<0.01, p<0.05) Mean daily intake levels of energy, protein calcium iron thiamin riboflavin and niacin were significantly elevated after the nutrition counseling and education program but were lower than the Recommenced Dietary Allowances. For the nutrition knowledge and food habits, the posttest mean scores showed a significant increase. The hematological status(hematocrit, serum ferritin) and the early follicle level of estradiol were elevated to a mild degree although it was not significant,. The follicular stimulating hormone level was elevated significantly(p<0.01) Gymnastica has been one of the sports implicated by the medical profession as having probable detrimental effects. The implications of such training to childs growth and maturation have yet to be determined . Most female athletes, however, experience poor nutritional status and delayed puberty The priorities were to prepared a more effective nutrition program and education material status and delayed puberty. The priorities were prepared a more effective nutrition program and educational material for athletes coaches and adminstrators to prepare guidelines for the team physicians and coaches to follow for the physical and physiological examinations of female athletes.

The purpose of this study was to investigate the anthropometric variables, dietary behaviors, nutrient intakes and distribution of serum lipid levels for Muan-gun inhabitants. The subjects was consisted of 212 men and 317 women. There were significant differences in the height, weight, BMI and fat mass with ages. In the onion intake status. 90.6(79.9)% of men(women) liked. 56.8(46.4)% of men(women) intakes 3 times per day, 29.6(40.8)% of men(women) 50g per one time and 83.1(87.5)% of men (women) after cooking. The mean energy intake of the subjects were 2,043㎉ for men and 2,105㎉ for women. Men (women) consumed 88(90)g protein. 34(38)g lipid, 340(355)g carbohydrate, 10.5(11.7)g fiber, 655(757)mg calcium. 1,396(1,421) mg phosphorous. 14.7(15.9)mg iron. 7.061(7,244)mg sodium, 3.597(3,704)mg potassium, 1.983(1,369)RE retinol, 1.4(1.5)mg thiamin. 1.1(1.4)mg riboflavin. 19.4(20.4)NE niacin. 172(160)mg ascorbic acid and 232(239) mg cholesterol. respectively. The level of triglyceride(TG) was 136.0(114.2)mg/dl, total cholesterol(TC) was 179.1(174.9)mg/dl HDL-C was 43.3(43.3)mg/dl, LDL-C was 109.6(107.9)mg/dl. VLDL-C was 26.8(22.8)mg/dl and AI was 3.2(3.0) And 68.1(79.0)% of men(women) were assessed as Normocholesteroiemia(NC) and 66.2(69.9)% of men(women) as Normotriglyceridemia (NTG). Most of the subjects in Muan-gun preferred and ate onions routinely and had normal range of serum cholesterol and triglyceride level. Therefore it is suggested that intake of onions is effective for decreasing the serum cholesterol and TG levels.
