  • The purpose of this study was to investigate satisfaction and preference for current military meal service and food behaviors and food habits of some military personnel in Chunchen and Wonju of the Kwangwon area. The results are as follows. In the anthropometric survey, average height of the subjects was 175.03 $\pm$ 5.30 cm, average weight was 69.15 $\pm$ 7.74 kg. As a result of surveying satisfaction in the current food service, an item high in satisfaction was adequacy of serving hours, whereas an item of low satisfaction was diversity of menu. The item of food service improvement needs of the subjects were in order more variety of menu, nutrition, preference, sanitation, cooking method. As a result of surveying eating behavior of the subjects, most items were high medium response. They preferred soju and relish and also they liked the bokkum cooking method. As a result of surveying food habits of the subjects, items of good habits were regularity of meals, marginal meals, diversity of food intake, dairy and dairy products, avoiding too exciting meals and natural food diet; whereas, items of bad habits were fast food intake, alcohol, smoking, carbonated and caffeine beverages, skipping breakfast. snacks, fatty food intake, yellow or green vegetable intake and fruit and seaweed intake. Following is the result of a survey on the preference of meals by cooking method serving the current military meal service. They liked one-dish meals such as Bokkeumbap, Bibimbap, Tteokguk, whereas, they disliked curryrice, Jajangbap. In case of soup, they liked soup made from meat better than vegetable soup or soup made with fish. Also they liked pot stem better than soup. Generally they liked meals containing meat in most cooking methods. These results suggest that continuous and practical nutrition education to change food habits in military life are necessary to Prevent chronic disease with increasing age.

  • Objectives: This study investigated the menu and nutritional contents of convenience store lunchboxes, and evaluated the nutritional content by meal type, price, and store brand. Methods: In September 2019, 93 convenience store lunchboxes from the top five franchise stores were purchased. Relevant information on price, food weight, food ingredients, cooking methods, and nutrition labeling were subsequently collected. Nutritional content was evaluated based on the daily value (DV) and Index of Nutritional Quality (INQ), and energy contribution of carbohydrate, protein, fat, saturated fat and sugar was compared with the recommended range. Results: Most lunchboxes included the food groups; grains/starches, meats/fish/eggs/legumes, and vegetables. However, none provided fruits, and only a few lunchboxes provided milk/milk products. Stir-frying, deep-frying, and pan-frying were the most frequent methods of cooking. The average energy content of the lunchboxes was 736.6 kcal, whereas the average contents of protein, fat and saturated fat were higher than 40% of the DV, and sodium content was 66.8% of the DV. The contents of most nutrients in traditional type lunchboxes were higher, as compared to nutrients in onedish type lunchboxes. Considering pricing of lunchboxes, protein and sodium contents were higher in the higher-priced lunchboxes as compared to lower-priced lunchboxes, but there were no differences in the INQs. The contents of energy, protein, fat, saturated fat, and cholesterol significantly differed by brand. Conclusions: Our results indicate that convenience store lunchboxes contain high levels of protein, fat, saturated fat, and sodium. The nutritional contents differed by meal type, price, and store brand, and higher price did not imply higher nutritional quality. We propose the need to educate consumers to check nutrition labels and purchase appropriate lunchboxes. Manufacturers also need to make efforts to reduce the amounts of fat, saturated fat, and sodium, and not provide protein in excess.

  • The study was designed to observe the correlation between the eating habits and growth development in 1,574 children (3-6 years old) in Kyunggi-do and Seoul, Korea. The eating habits and nutrient intake were determined by mini dietary assessment and food frequency questionnaire (FFQ). 35.6% children had been practicing an unbalanced diets. Children with unbalanced diet consumed less amount of protein source foods (meat, fish, egg, soy products), vegetables and fruits and had irregular meal time, but more of them preferred sweet foods (ice creme, cookies) and carbonated drinks as snack compared with children in balanced diet. 24-35% children consumed energy, iron (Fe), calcium (Ca), Niacin, Zinc (Zn) less than 75% RDA. Energy intake of children with unbalanced diet was not significantly different from those with balanced diet, but they consumed less amount of niacin, Fe, Ca and Zn than those with balanced diet. By using the relative percentage of standard weight-length-index (WLI), 65.7% children was normal weight, 12.9% was underweight, 13.4% was overweight and 7.9% was obese. However, 11.9% of underweight and normal weight children was so called thin obese since their body fat content was greater than 20%. There were 16.8% underweight in children with unbalanced diet and 12.6% underweight in those with balanced diet. Compared to normal weight, the underweight children significantly consumed less amount of milk and its product, high protein foods, fried foods and fruits, but obese children consumed more high protein source foods (meat, fish, egg, etc) and sweet foods. In conclusion, the eating habits of unbalanced meal was prevalent problem in preschool children which resulting in their health risks. Therefore, it would be needed that new approach for nutrition education to improve eating habits in preschoolers.

  • This study was conducted to determine the supplemental effects of two insect meals, mealworm (MW) and black soldier fly (BSF), with high or low lipid levels in diets, on Pacific white shrimp Litopenaeus vannamei. Sardine and tuna by-product meals were used as the fish meal source in a control (Con) diet. The fish meals were replaced with MW, defatted MW (deMW), BSF or defatted BSF (deBSF), respectively. The shrimp (body weight: 0.47 g) were stocked into 20 acryl tanks (215 L) and fed the diets six times a day. After 45 days of the feeding trial, the shrimp that were fed insect meals had significantly higher phenoloxidase and superoxide dismutase activities than the shrimp fed Con diet. The gene expressions of prophenoloxidase, crustin and penaeidine-3c in shrimp hepatopancrease were also higher in shrimp that were fed the insect diets, regardless of defatting than those in shirmp that were fed Con diet. The survival against Vibrio parahaemolyticus was higher in shrimp that were fed the diets containing defatted insect meals than in shrimp that were fed Con diet. These results indicate that MW and BSF, regardless of lipid levels, could be good protein sources for the enhancement of innate immunity and anti-oxidant capacity of the shrimp.

  • Objective: The objective of the current study was to investigate the effects of dietary hatchery by-products (HBPs) as a replacement of fish meal (FM) on growth performance, relative organ weight, plasma measurements, immune organ index, meat quality, and tibia characteristics of broiler chickens. Methods: A total of 720 broiler chickens (3 d of age) were randomly allotted to 1 of 9 treatments with 8 replicates. Each replicate consisted of 5 male and 5 female birds. The basal diet was formulated to contain 5.0% commercial FM, whereas eight treatment diets were prepared by replacing 25%, 50%, 75%, or 100% of FM in the basal diet with infertile eggs (IFE) or a mixture of various HBPs (MIX); therefore, the inclusion levels of IFE or MIX in the experimental diets were 1.25%, 2.50%, 3.75%, or 5.00%. The diets and water were provided on an ad libitum basis for 32 d. Results: Increasing inclusion levels of IFE as a replacement of FM in diets had no effects on growth performance, plasma measurements, immune organ index, and tibia characteristics of broiler chickens. Increasing inclusion levels of IFE in diets increased (linear, p<0.05) meat lightness (L*) but decreased (linear, p<0.05) meat redness (a*). The breast meat pH at 1-h postmortem was increased (linear, p<0.05) by increasing inclusion levels of IFE in diets. Likewise, increasing inclusion levels of MIX in diets had no effects on growth performance, relative organ weight, plasma measurements, immune organ index, and tibia characteristics. However, increasing inclusion levels of MIX in diets increased (linear, p<0.05) 1-h postmortem pH but decreased (linear, p<0.05) 24-h postmortem pH of breast meat. Increasing inclusion levels of MIX in diets decreased (linear, p<0.05) thiobarbituric acid reactive substances values of breast meat. Conclusion: Both IFE and MIX are suitable alternatives to FM as protein ingredients in broiler diets.
