Based on the nutritional component analysis data of the Rural Development Administration, the change in the main nutrients of vegetables for 40 years from 1981 to 2021 was investigated. Nutrients that showed a decreasing tendency during the investigation period in fruit vegetables were calcium, iron, thiamine, riboflavin, and ascorbic acid, etc. In root vegetables, it tended to decrease in calcium, thiamine, riboflavin, niacin, and ascorbic acid, etc. In leaf vegetables, it tended to decrease in iron, niacin, and ascorbic acid, etc. In leaf and stem vegetables, it tended to decrease in energy, phosphorus, iron, thiamine, riboflavin, niacin, and ascorbic acid, etc. In particular, it has been confirmed that vitamin reductions such as thiamine, riboflavin, niacin, and ascorbic acid, which have important meanings in vegetable intake, have occurred in vegetables over the past 40 years.

최근 식생활의 서구화로 인해 기호식품의 사용량이 증가하고 설탕섭취량은 계속적인 증가를 보이고 있다. 특히, 아동들이 우리의 전통식생활에서 멀어지고 단 맛 위주의 스낵류나 과자 케일 등과 같은 기호식품의 사용으로 인한 설탕섭취량이 증가하고 있다. "식품수급표"상에 나타난 설탕공급량을 위주로 우리 국민의 설탕소비패턴과 국제간 비교를 통해 한국인들의 설탕섭취수준이 어느 정도인지를 파악하고 단맛에 대한 한국인의 기호도의 변화과정을 살펴보았다. "2001 국민건강영양조사"에서는 한국 성인 1일 1인당 약 60 g 정도의 설탕 섭취량을 보였다. 농림부의 "식품수급표"를 중심으로 살펴보면 2002년에 1인 1일당 설탕공급량이 57 g으로 나타나 미국인의 1일 설탕섭취량인 130 g 정도인 것에 비하면 아직도 적다고 볼 수 있다. 그러나 1962년에 4.8 g이었던 것을 생각하면 상당히 증가하였다. 식품수급표상에 나타난 국제 통계 비교치에서는 한국인의 1일 설탕공급량을 99g 으로 잡고 있어 실제로는 한국인들의 설탕섭취량이 상당한 수준으로 올라왔음을 짐작케 한다. ISO의 국제 비교에서는 1년 1인 소비량이 22.7kg으로 전 세계 국가 평균 소비량을 상회하고 있다. 아동의 가공식품 소비로 인한 설탕섭취량은 급속히 증가하였고, 현재 급속히 증가하고 있는 아동비만 현상과도 관련이 있다. 1995년에 행해진 초등학생들의 설탕섭취실태자료를 통해 볼 때 이미 10년 전에도 도시지역이 아닌 농촌 지역 아동의 설탕섭취량이 이미 60 g 이상을 넘어서고 있었고 급원식품에서 성인들이 주로 과일류 의존이 높았던 반면 아동들은 간식류에서의 설탕섭취가 매우 높았다. 따라서 연령별로 매우 자세한 간식 목록에 의거한 설탕섭취량 조사가 무엇보다도 필요하다. 현재 한국의 식품성분표에는 다양한 한국음식에 대한 설탕함량 Database가 없으므로 미국의 USDA Database를 기초로 한국 식품의 설탕 함량을 추론해야 하는 어려움이 있다. 따라서 다양한 한국음식의 설탕함유량에 대한 Database구축이 무엇보다도 필요하다고 보인다.

A computerized nutrition counseling system for patients having diabetic symptoms has been developed using a personal computer compatible with IBM PC 386. This system is composed of three programs. The first program is designed to find out a personal dietary history and to give suggestions about his incorrect dietary habit. The second one is analyzing the energy and nutrients of food consumed. The analyzed data present the evaluated personal dietary status. With these data, patient could replan his food including snacks as well as regular meals. The third one is the diet and menu planning program that provides the patient with a suggested meal pattern using food exchange table. Practicing these programs, diabetic patient could help himself very conveniently in organizing his meal plan and in improving his dietary behavior.

전 세계적으로 건강, 환경보호, 윤리적 소비를 추구하는 소비자들이 증가하면서 다양한 분야에서 동물성 제품을 섭취하거나 소비하지 않는 생활방식인 비거니즘(Veganism)을 지향하는 사람들이 증가하고 있다. 한국 또한 매년 채식에 대한 관심이 높아지고 있지만 외국에 비해 채식하기에 좋은 환경은 구축되어 있지 않으며 가공식품을 구매할 경우 성분 표를 일일이 확인해야 하는 어려움이 있다. 본 연구에서는 사용자가 섭취하고자 하는 가공식품의 성분을 분석하여 본인의 채식주의자 단계에 적합한 제품인지 쉽게 판별할 수 있는 모바일 앱을 제안한다.

A computerized dietary prescription and nutritional counseling system for patients having hyperlipidemia has been developed using a personal computer. This system is composed of three programs. The first program is designed to investigate dietary history of patient, such as a dietary habit and a preference of food, to find out his incorrect dietary behavior and to give him some suggestions to correct dietary behavior. The second one is developed to analyze the energy and nutrients intake using 24-hour dietary recall method and also evaluate the status of dietary intake, especially the status of dietary fat. With these data, patient can replan pattern of his food intake including in-between-meal snack as well as regular meals. The third one is the diet and menu Planning program made using food exchange table. It provides the patient with a meal pattern suitable in his weight, activity and the other status of the body. Practicing these programs, patient with hyperlipidemia can help himself very conveniently in organizing his meal plan and in improving his dietary behavior.

This study analyzed food component characteristics and antioxidant activities in five kinds of domestic commercial shiitake mushrooms (Lentinula edodes). Moisture content (79.17-82.90 g/100 g) showed little difference, but there was a significant difference in crude protein content. Total mineral content showed a significant difference, and potassium (K) content was the highest. Total and essential amino acid contents were higher in mushroom A than in the other samples. Nonetheless, the ratios of essential amino acids, aspartic acid, and glutamic acid to total amino acids were similar in all samples. 𝛽-Glucan content was in the range of 10.28-5.68 g/100 g, exhibiting a significant difference. The color intensity and overall texture of the mushrooms showed no remarkable difference. Total phenol and flavonoid contents were in the range of 19.92-30.77 mg/100 g and 6.95-10.39 mg/100 g, respectively; the ratio of flavonoids to total phenols ranged from 31.53% to 38.21%. DPPH and ABTS radical scavenging activities were 74.92-79.04% and 80.47-84.97%, respectively, and showed little difference. However, the reducing power varied between 195.23 𝜇M and 317.85 𝜇M, displaying a significant difference in all samples. Therefore, this study observed similar trends in the food component characteristics and antioxidant activities of domestic commercial shiitake mushrooms.

In order to provide food factors necessary for safety assessment and standard setting of hazardous substances in foods, per capita consumption of food items by Korean population was optimized for the periods of 1970's and 1980's from nutritional survey and food supply data. Average daily intake of total foods per person was 1,104 g in 1970's and 1,240 g in 1980's. Much variation was observed between the two decades by food commodities.

Vitamin E and K are essential micronutrients required by our body in small amounts for proper metabolic functions; however, the content of vitamin E and K commonly consumed in foods has not been comprehensively defined. In this study, the contents of vitamins E and K in sea algae and vegetables were analyzed and the analytical methods were validated. The α-tocopherol equivalent (α-TE) and vitamin K1 content in sea algae ranged from 0.15 to 1.14 mg/100 g and from 11.91 to 1,629.5 ㎍/100 g, respectively. In addition, α-TE and vitamin K1 of vegetables were detected in the range of 0.02-2.48 mg/100 g and 16.15-979.60 ㎍/100 g, respectively. In particular, β- and γ-tocopherol and α- and β-tocotrienol were detected in several vegetables. The analytical methods were accurate and reproducible. These results provide reliable data on the vitamin E and K contents of foods consumed in Korea for the development of National Standard Food Composition Database.

This study was designed to compare various dietary assessment methods and to determine the appropriate method that would be reliable for monitoring the adherence to a fat-modified diet. Dietary intake data was collected from the twenty-two (12 males, 10 females), type IIa hypercholesterolemic patients by the 24-hour dietary recall and the food records of various durations(9, 7, 4, 3days). Intakes of energy, protein, fat, carbohydrates, cholesterol, polyunsaturated fatty acids, saturated fatty acids, monounsaturated fatty acids, P/S ratio, and alcohol were analyzed by a computer-assisted method using the Natinal Heart, Lungand Blood Institute Nutrition Data System. The nutrient intake data of the 24-hour recall method were consistently higher than tat of the food record method. In all subjects, food record keeping of the 7 consecutive days provided acceptable dietary data (within 5% difference) when compared to that of the 9 consecutive days. Food records of 4 consecutive days however, were found to be adequate for female subjects, showing a sex difference. Except for P/S ratio, nutrient intakes did not vary significantly between weekdays and weekend-days. Among other components, alcohol and P/S ratio were shown to be the two most varied components in this study.
