The Korea National Health and Nutrition Examination Survey of 2013 to 2017 reported that the average protein consumption of the Korean population is above the current recommended nutrient intake of protein proposed by the Dietary Reference Intakes for Koreans. Some health professionals and the media often advise consuming diets high in protein for promoting metabolic regulation, weight control, and muscle synthesis. However, due to lack of scientific evidence, the validity and safety of high protein consumption are yet to be fully ascertained. The present review assesses recent evidence published in 2014-2020 from human studies, focusing on adequate protein intake and protein sources for the prevention of chronic diseases, particularly metabolic disorders and sarcopenia.

The purpose of this study was to assess dietary intake and food habits of low-income person aged 60 years or eldary. The hundred fifty persons from the suburbs of Jeonju were surveyed between August 1 to 20,1979. Results were as follows: Family environment Approximately 90% of elderly persons surved, lived with their children and grand-children: 5.2% together as a couple; and 4.4%, widowed, lived alone. Nearly 40% of the households has a average monthly incomes of W40,000 to W100,000. Average food expediture accounted for 50 to 70% of total monthly income, thus indicating that the subject families belonged to the lowest socioeconomic level. As pocket money, 74.5% of male subjects had more than W5,100 per month. whereas, 51.4% of female had less than W5,000. Anthropometric measurements: 97.6% of subjects has heights greater than 90% of the Korean standard for their age group, whereas 45.2% of the subjects were 60 to 89% of standard weight. 88% had an arm circumferences only 60 to 89% of the standard. Nutrient intake: Intake of the majority of nutrients was below the recommended allowances, especially for energy, protein, calcium and iron. The energy input ratio of carbohydrate: protein: fat was 73.1-80.9. 13.3-15.8: 4.5-11.5, showing very heavy dependence on carbohydrates for energy needs. The contribution of animal protein was 24.3% of total protein intake, indicating an improper protein diet. Other factors influenced on the nutrient intake: Poor teeth, illness, and poor appetite were always associated with inadequate intake of energy and nutrients. The larger the family size, the lesser intake of nutrients was observed among those elderly.

The purpose of this study was to develop the website-based program for individual meal planning. The program consisted of the basic information of clients, dietary habits, analysis of nutrient intakes and menu planning. The first part of the program consisted of general information such as general characteristics and anthropometric data of clients. The second part was designed to investigate the dietary habits, food intake frequency, nutrition knowledge, and drinking and smoking habits of the clients. The third part consisted of analysis of nutrient intakes including three major nutrients, calorie intake by foods and alcohol, and ratio of individual fatty acid intake. Nutrient intakes was evaluated by comparing with dietary reference intakes. In the final part, the program included the menu planning by using standard recipe. This system was also designed to insert, remove or change the food items or amount according to the user need. It is expected that the development of a meal planning system based on the internet can facilitate the professional dietary counseling, and thus help to improve the health of people.

A nutrition survey of 152 children , in the kindergarten attached to a proivate elimentary school of Pusan, was undertaken between Dec. 1 and Dec.14, 1993, to investigate dietary intake and nutrition status. The results are summarized as follows. 1) Compared with the Korean child development standard, their development conditions showed 113.1% , 102.2% , 103.3%, 101.75 in weight, height, head and chest, respectively. 2) By the standard of WLI(Weight Length Index) , proper to the children between age 4 and 6 , there proved to be 25% overweight and 4% obesity, 25% overweight and 19% obesity , 28 overweight and 26% obesity in 4-year-old, 5 year-old, and 6 -year-old children, respectively. 3) The children between age 4 and 6 averaged 37.6% in hematocrit and 12.4-12.8 5 in hemoglobin. these values were higher than those of the Korea child development standard. but the numbers of erythocyte, leucocyte and platelets were normal . Only a single child was considered suffering from aenmia . The 8% of them were over 200mg/이 in cholesterol, dangerously approaching the atherosclerosis. The 31% averaged 120mg/이 in triglyceride . And the 6% proved 100mg/이 in blood glucose when hung교. So it came out that not a few children had some factors dangers to diabetes, atherosclerosis and heart diseases : complications arising from obesity. 4) The intake of nutrients , except the 4-year-old children , ranged 108.4% to 2665 from the recommended value. The rates of carbohydrate, fat and protein to be much correlation among total intake of nutrients, development , results of blood test and WLI. The degree of obesity was proportionate to the intake of nutrients.

The purpose of this study was to investigate the effect and correlation of anthropometric data, eating behaviors, and nutrient intake on the bone mineral density(BMD) of female college students. 349 female college students were surveyed and their age, height, and weight were an average of 20.5 years, 163.2 cm and 54.0 kg, respectively. Their average BMI was 20.2, with 66% falling in the normal range, 21.8% classified as underweight, 8.0% as overweight, and obese individuals comprised 3.4% of the sample by BMI classification. Calcaneal BMD was measured and the average T-score was 0.117. The results of BMD measurements were normal in 268 people(76.8%), osteopenia was found in 71 individuals(20.3%), and osteoporosis in 10(2.9%), respectively. There was a significant difference in bone mineral density according to height(p<0.05) and BMI (p<0.01). There were significant differences between BMD and eating behavior, regularity of eating behaviors(p<0.05), instant food intake(p<0.05), eating out(p<0.05) and nutritional supplement intake(p<0.05). In addition, normal the group with normal BMD had a more desirable eating behavior compared to the osteopenia and osteoporosis afflicted groups. BMD had a significant difference according to the nutrient intake of calcium(p<0.05), vitamin A(p<0.05), and vitamin C(p<0.05). In conclusion, BMD showed a good correlation with height(p<0.01), BMI(p<0.01), body composition including total body water(p<0.05), FFM(p<0.05), body protein(p<0.05) and intake of calcium(p<0.05), iron(p<0.05), vitamin A(p<0.05), and vitamin C(p<0.05). Therefore, an education plan and training on balanced diets proper body weight control, and desirable eating behaviors for female college students will be needed.

Purpose: In this study, we assessed the intake of nutrients and food groups and analyzed the nutrition quotient of obese children in South Korea. The hypothesis was that dietary quality and nutrient intake are related to the body mass index (BMI) of obese children. Methods: The participants included 48 children (20 boys and 28 girls). Based on the guidelines for the age-for-body mass index provided by the Korean National Growth Charts for children and adolescents, the participants were divided into 3 groups: overweight, BMI ≥ 85th percentile; obese, BMI ≥ 95th percentile; severely obese, BMI ≥ 99th percentile. Results: The energy distribution showed that the carbohydrate ratio was significantly higher in the overweight group (p < 0.01), whereas the fat ratio was significantly higher in the obese and severely obese groups (p < 0.05). Thus, in the overweight and obese groups, the percent body fat was negatively associated with the carbohydrate ratio (p < 0.05) but was positively associated with the fat ratio (p < 0.05). The Dietary Reference Intakes (DRI) data revealed that the intake levels of protein, vitamin B₁, vitamin B₁₂, and sodium were higher in all groups. Intakes of fiber, calcium, potassium, and magnesium were insufficient in all groups, and the DRI percent for protein was significantly higher in the obese and severely obese groups than in the overweight group. No significant differences were obtained in food group patterns or Nutrition Quotient (NQ) scores among the 3 groups. According to the evaluation results by food record and NQ, a significant difference was obtained in the dietary quality of obese children. Conclusion: We conclude that a higher intake of fat enhances weight gain. Based on the study results, we propose that the guidelines should consider the energy distribution of carbohydrate and fat intake to prevent and control obesity among Korean children.

The purpose of this study was to estimate the daily intake of vitamin A in Korean female university students. Vitamin A intake was estimated using an inconsecutive 3-day dietary intake survey from 481 young women. Vitamin A intake values were calculated based on the data in USDA database. Average age, height, and weight of the subjects were 20.05 years, 162.13 cm and 54.38 kg, respectively. The subject's average intake of energy was 1645.67 kcal. The mean vitamin A, retinol and ${\beta}$ carotene intakes were $908.35{\pm}863.18$ ug retinol equivalent/day, $199.19{\pm}166.00$ ug/day and $3872.59{\pm}4972.17$ ug/day, respectively. The 21.83% of the subjects consumed less than the Estimated Average Requirement (EAR) for vitamin A. And subjects consumed 141.69% of the Recommended Nutrient Intake (RNI) for vitamin A. Food groups consumed with high vitamin A content in our subjects included vegetables (423.96 ug RE/day), potato and starches (213.64 ug RE/day), cereals (62.60 ug RE/day), eggs (55.17 ug RE/day) and milks (53.45 ug RE/day). The major food sources of vitamin A were sweet potato, carrot, spinach, egg, and cereal, and the top 30 foods provided 89.57% of total vitamin A. Also animal-derived food provided 9.65% of the vitamin A intake from the top 30 foods. In conclusion, judging from RNI, the vitamin A intake of the Korean female university students in this study was generally adequate. The result of our study may be used as a basis for follow-up studies of vitamin A intake like assessment of vitamin A nutritional status or evaluation of carotenoid food sources in Korean young women.

본 연구대상자들은 열량공급 영양소인 탄수화물 : 단백질 : 지방으로 부터 각각 전체 열량의 63% : 14% : 24%를 공급받아 한국인의 권장비인 65 : 15 : 20에 근사한 값을 보여주고 있다. 이러한 이상적인 섭취양상은 sucrose/starch ratio나 P/S ratio cholesterol 등에서도 바람직한 섭취수준을 보여주고 있어 본 조사대상자는 식이를 통한 고혈압 위험인자를 비교적 적게 갖고 있는 것으로 나타났다. 단, 섭취량이 위험수준 이상 보다 높을 것으로 기대되는 나트륨의 섭취량은 조리과정에서 첨가되는 식염의 양을 측정하지 못하여 그 위함의 심각성을 도출하지 못했다. 영양소 섭취의 식품공급원의 순위와 개인간의 변이식품의 순위는 일반적으로 모든 영양소(열량, 단백질, 지방, 나트륨, 칼륨)에서 크게 다른 것으로 나타나 영양소의 주된 공급식품을 중심으로 빈도조사법의 설문지를 작성할 경우 개인간의 섭취량의 차이를 찾아내는데 크게 실패할 가능성을 보여주고 있다. 단, cholesterol의 경우는 제한된 식품에 의존해서 공급받는 것으로 나타나 공급식품과 변이식품의 순위가 크게 차이 나지않아 빈도조사법 설문지 개발시 주된 공급식품의 섭취빈도 조사만으로도 개인간의 변이를 충분히 반영할 수 있는 것으로 나타났다. 그러므로 질병과의 관련성을 규명하기 위해 식이조사에서 식품섭취 빈도법을 이용하여 설문지를 개발할 경우 주된 급원식품만을 포함시킨다면 개인간의 섭취량의 차이를 도출해 낼 수 없으나, 포함되는 식품항목의 금원식품 뿐 아니라 변이식품도 포함시키는 것이 개인간의 영양소 섭취의 차이를 찾아낼 수 있는 좋은 방법임을 본 연구결과는 시사하고 있다. 본 연구는 고혈압의 식이성 위험인자가 되는 영양소를 중심으로 개인간의 섭취량의 차이를 규명하기 위한 식이조사를 한다는 전제하에 조사에 사용될 식품섭취 빈도법의 설문지 개발시 포함시켜야 할 식품항목의 타당성을 공급식품과 변이식품의 순위 분석을 통해 관찰해 봄으로써 조사표 작성의 기초자료를 제공하고자 하였다. 앞으로 고혈압 이오의 다른 질병인 경우에도 이와같은 연구가 진행되어 각각의 질병연구에 적절한 조사표 작성의 기초자료들이 제공되어야 역학연구에서 식이조사의 효율성을 기대할 수 있을 것이다.

This study was performed fir the purpose of finding the relationship between fat-free mass (FFM) which mainly represents muscle mass change, and muscle strength. The correlation between diet and exercise behaviors and FFM in healthy elderly men over age 55 was also investigated. FFM and corresponding hand grip strength declined significantly with increasing age. However the concentration of serum albumin, the indicator of protein nutritional status, showed no change with increases in age. The subjects were categorized into three groups according to FFM textiles. Anthropometry such as height, BMI, circumferences of waist and hips, body fat mass percent and hand grip strength decreased significantly in the lowest FFM group. But albumin level showed no change relative to FFM level. FFM showed a significant relationship to nutrient intake such as energy and fat. However, no association was found with exercise behavior probably because there were no instances of resistance exercise habits among the subjects studied. The variance in FFM could be attributed 86.2% to height and age. The variance of height-adjusted FFM could be attributed only 40.6% to age and fat intake. In conclusion decreases in FFM may cause reductions in muscle strength in elderly men. Increasing energy and fat intake were associated with increased FFM and may protect elderly men from the risk of sarcopenia. FFM had no association with endurance exercise habits.
