Plant-based, grain-free, and gluten-free diets have been the focus of recent research, as part of the premiumization trend in dog food. However, the lack of comprehensive information regarding carbohydrates in dog food makes it difficult to produce nutritionally balanced meals. Therefore, we aimed to evaluate the nutritional value of carbohydrate ingredients commonly used in commercial dog foods. First, using data from Euromonitor, we investigated the trends in the dry dog food industry and analyzed the annual volume of dry dog food sales, as well as the dog population from 2010 to 2021 in Korea. The growth of the market was greatest in 2021, when the total value of sales of premium dry dog food was 254.3 billion KRW (Korean won) more than in 2010. In addition, sales of dry dog food by age category were marked by a significant increase (404.8%) in the market for dry food for senior dogs. Second, we examined the frequency of carbohydrate ingredients used in dry dog food and conducted a proximate analysis of the top 10 most frequently used ingredients. Subsequently, we analyzed the crude protein, crude fat, and nitrogen-free extract in the carbohydrate ingredients based on dry matter (DM) and calculated the ratio of metabolic energy content supplied from each nutrient in the carbohydrate ingredients. The ratio of metabolic energy content in the carbohydrate ingredients indicated that mung beans had the highest crude protein content (31.3%), whereas oats exhibited the highest crude fat content (23.3%). Sweet potatoes had the highest nitrogen-free extract content, measuring at 93.6%. The results of this study are expected to provide a valuable foundation for the growth and development of the domestic dog food industry, while also contributing to a deeper understanding of the specific role of each ingredient as a carbohydrate source.

For the purpose of investigating the weaning practice for infants, this study of 251 infants aged from 3 months to 2 years old was conducted in Daejeon City during the the period of August 9 through 23, 1978. The results obtained were as follows: About 60% of the infants were breast-fed, 27.6%, mixed-fed, and 12.0%, bottled-fed. The reason for bottle-feeding was either the lack of breast-milk secretion or ill-health of mothers. There was no significant difference in the feeding methods according to a level of mother's education. Sixty precent of the infants began to be weaned 6. months. The most of the infants were completely weaned within 18 months. The knowledge on weaning was mainly obtained from the publications, such as newspapers, journals for women, child care booklets, etc. The difficulties in the weaning practice were the shortage of knowledge on weaning and the unacceptability by the infants. Liquid or semi-liquid foods were firstly given to the more than 60% of the infants as introducing weaning foods, while 23.3% of the babies were given solid foods. Interestingly, the earlier the birth order was, the more babies were given liquid or semi-liquid foods, The motives for weaning was either the boby's demand for other foods than milk(41.3%) or the lack of breast-milk secretion (31.3%). In the selection of supplementary foods, the nutritional value was given the highest consideration) (54.9%). many mothers (64.2%) prepared supplementary foods for infants at home, while 23.1% used commercial body foods and 12.7% gave infants adult's meals as supplementary foods. The major materials for home-made supplementary foods were fruits and vegetables (41.5%) and cereals (37.5%). The commercial supplementary foods (mainly powdered from) were not used much (never used; 53.6%) and even in the babies, who had consumed them once, nearly half of the babies (42.9) did not eat well. Accordingly, the many mothers (68.8%) welcomed the development of the domestic supplementary foods in good quality and one-third (31.2%) responded that they would consume them regardless of the price.

In order to investigate the types of enteral nutrition formulas currently used in hospitals and evaluate and categorize the commercially prepared enteral nutrition formulas formulas available in the domestic market, we asked dietitians working in 6 hospitals in Seoul to complete the questionnaire and obtained compositional characteristics of 12 commercially prepared enteral nutrition formulas. The average proportion of patients receiving the commercially prepared enteral nutrition formulas(60.6%) was greater than that of patients receiving the in-hospital preparations(31.9%). In the group of patients receiving the in-hospital prepared formulas, the enteral feeding was mainly administered orally, whereas, in the group of patients receiving the commercially prepared formulas, tube feeding was the primary route of formula administration. In both groups, however, a greater proportion of patients received the formulas as total replacements of their meals and for the purpose of dietary supplementation. On the basis of major criteria for evaluation of the commercially prepared enteral nutrition formulas, the 6 products out of the 9 nutritionally complete products formulated for the purpose of dietary supplementation were grouped into the same category(standard protein, caloric density of 1kcal/ml, and tube/oral), so they were considered therapeutically comparable. However, the remaining 3 products were different in protein content(high protein) or route of administration(tube only). Of the 3 nutritionally complete products formulated specifically for the purpose of dietary therapy, 2 products were formulated for patients with renal disease, and the one product was formulated for diabetic patients. Therefore, the data in this study showed that the commercially prepared enteral nutriton formulas became an important part of the enteral nutrition for hospitalized patients in Korea, but the domestic market has not yet generated a wide variety of the formulas, not providing many choices for clinicians to manage the diets for their patients. The results of this study would be helpful for clinicians in choosing appropriate products for their patients, for manufactures in developing new products, and for regulatory authorities to establish the regulation for the broad group of heterogeneous products that are marketed and will be developed as medical foods. In addition, the process of maintaining the categories for evaluation of the commercially prepared enteral nutrition formulas should be dynamic because new products may not reasonably fit any of the existing categories.

This study was undertaken to develop web-based nutrition information contents for the older adults. Twenty six domestic web-sites were analyzed and then 12 foreign web-sites and 4 education materials for the elderly of foreign university were benchmarked. Also a lot of literatures on elderly education program were reviewed. A card-sorting task was performed with 8 older adults to ascertain how the target audience organized information about nutrition. The results were as fellows. Among 26 domestic web-sites, 2 sites(7.7%) were only for the elderly. Main topics of information contents for the elderly included 'Importance of Healthy Eating', 'DRI', 'Dietary Guidelines'. Four of twelve foreign web-sites were for the elderly nutrition education. Topics of 'Dietary Guideline', 'Meal Program' were found in 4 sites and 'Importance of Healthy Eating', 'Diet & Disease', 'DRI, 'Food Guide Pyramid', 'Nutrition Fact Labels' were found in 3 sites. Education materials of foreign university dealt with basic information on 'nutrient needs changes related with aging', 'Heart & Bone Healthy Eating Plan', 'Food Guide Pyramid'. Also topics on 'Eating on a budget', 'Eating Out Guideline' were included for practical use for the elderly. Based on card-sorting process, contents framework for web-site was developed and 4 main menus for framework were respectively named as 'Nutrition', 'Meals', 'Foods'. 'Check up Nutritional Health' by panel discussion. Finally we developed nutrition information contents for 4 main menus. We focused on helping older adults recognize the importance of healthy eating and apply the nutrition information to practical use. We expect that the developed framework of contents can be a guideline for indentifying the information needs of older adults in developing effective nutrition intervention program. And we suggest that the survey for target people should be peformed for the web-site to be user-friendly designed and the developed contents be evaluated and revised in the near future.

Substitution effect of fish meal and Saccharina japonica with soybean and rice bran in extruded pellet (EP) on juvenile abalone was determined. Two thousand five hundred and twenty juvenile abalone were distributed into 36 plastic containers. Four EP were prepared and extruder-pelletized. Twenty percent fish meal, 12% soybean meal and 14% Saccharina japonicawere included in the Control diet. Fifty percent of fish meal, combined 50% of fish meal and Saccharina japonica, and 100% of fish meal and Saccharina japonica were substituted with the same amount of soybean meal, and combined soybean meals and rice brans, referred to as FS50, FS50+SS50 and FS100+SS100 diets, respectively. Four domestic and 3 imported commercial diets for abalone and salted Saccharina japonica were prepared. The diets were fed to abalone once a day for 16 weeks. The highest survival was obtained in abalone fed FS50+SS50 diet. Weight gain and SGR of abalone fed FS50+SS50 diet was higher than those of abalone fed the FS50 and FS100+SS100 diets. Proximates of abalone was affected by dietary nutrient composition. In conclusion, 50% fish meal and combined 50% fish meal and Saccharina japonica could be replaced with the same amount of soybean meal and combined soybean meal and rice bran in EP of abalone.
