The waste rates of 98 food items after pre-preparation were surveyed to provide database for good menu planning. The waste rates turned out 0-64.27% in vegetables, 6.38-7.03% in potatoes, 6.25-68.75% in fishes and shellfishes, 16.61% in eggs, and 16.00-56.84% in fruits. Foods with high waste rates were vegetables, fishes and shellfishes. Survey results were compared with other food composition tables. Foods with 30% higher waste rate than other food composition tables were squash leaf, pacific ocean perch, sweet potato stalk, water cress, green peas, alaska pollack, bluefin tuna, beka squid, crown daisy, dodok, amaranth, beef ribs. Food which waste rates turned out to be decreased by about 30% in this study were corb shell, pomfret, sea mussel, warty sea squirt. For the menu planning, reasonaly exact waste rates for each food items are essential. Since survey results show significant deviations, there should be more studies for exact waste rates for each food.

The purpose of this study is to evaluate nutritional status of ascorbic acid in 96 Korean female college students. Dietary intake level was estimated with three day diet records. Serum ascorbic acid were analyzed with fasting blood. Nutrient intakes was calculated using three different food composition databases ; analysis data of cooked food items ; analysis data of raw foods ; published food composition table. Ascorbic acid intake levels calculated with different food composition databases differed by 15% Using analysis data of cooked foods resulted in the lowest intake level 49.26 mg per day. Main sources of ascorbic acid investigated were Cheju mandarin orange juice and hard persimmon orange juice and Kimchi. Mean value of serum ascorbic acid level was 1.04 mg/dl and 4.2% of subjects were in marginal risk or deficient range. It was found to significantly correlate asscorbic acid intake with serum ascorbic acid content. Correlation coefficient with results calculated using analyzed data was higher than that using published data. Serum levels and mean daily intake levels of ascorbic acid in the subjects were significantly correlated. From these results it is concluded that ascorbic acid content of cooked foods should be included in the Food Composition Tables in Korea. Korean female college students were in lower risk of ascorbic acid deficiency.

In this study, Artemisia capillaris, which has been used in oriental medicine and folks remedy, was investigated to characterize the nutritional composition (protein, lipid, ash, fiber, amino acids, fatty acids, Na, K, P, Mg, Ca and Fe) and effective substance (scopoletin). Artemisia capillaris has often been cited in medical literature for its medicinal effects. The Korean Food and Drug Administration allowed Artemisia capillaris as a food stuff and indicated as In-Jin-Sook. From the view point of the subjects who eat In-Jin-Sook products, most of them ingested it for a certain pharmacological efficacy rather than as a beverage or a food. Therefore, we need to develop functional foods using In-Jin-Sook. Artemisia capillaris was superior in protein, crude fiber, amino acid and fatty acid compositions to wild greens according to Korean Nutritional Composition Table. Also scopoletin, blown for blood vessel relaxation and hypotensive effect, was detected at the level of 326.13 $\mu\textrm{g}$/g. These results demonstrated that Artemisia capillaris has both pharmaceutical effects and balanced nutritional contents. Artemisia capillaris has sufficient values to use as a food stuff for functional foods.

Due to the continuous change of socio-economic circumstances and dietary pattern, the need to change recommended dietary allowances and the basic food groups has been required. Consequently, there have been six revisions of the Korea RDAs, the national recommanded dietary allowances. I reviewed the six sequences of revisions concerning the basic food groups. Up to the fifth revision, the ranks of the basic food groups were based upon the dietary needs of the people of the perspective era. However, in the sixth revision, there was no rank associated with the food groups, but the food groups were portrayed in a food composition tower that explained their importance and their necessary consumption amounts. I could indirectly observe the dietary pattern of each era by analyzing the basic food groups and the representative foods of each food group. I also studied information of pictorial representations of the basic food groups and compared the items of the representative foods with nutrient analysis table. By observing nutrient analysis table, I analyzed whether the clarified representative foods of the basic food groups are indeed foods that were eaten frequently by people daily.

This study was conducted to investigate the relationship between lactational capacity and intakes of energy and energy-yielding nutrients. Food consumption, intakes of carbohydrate, protein, fat and energy and quantity and proximate composition of milk of 11 lactating Korean mothers were determined at 1, 2 and 3 months postpartum longitudinally. Food consumption was estimated using a 24-hour recall method ; intakes of energy and energy-yielding nutrients were calculated according to the Food Composition Table. Daily milk production was estimated using a 72-hour test-weighing method ; protein, fat, lactose and energy concentrations were analyzed. Average intakes of energy and protein were 1974$\pm$386㎉/day and 67.0$\pm$12.3㎉/day, these were 73% and 74% of the Korean Recommended Allowances, respectively. Average milk yield was 720.1$\pm$123.3ml/day containing energy 59.6$\pm$9.5㎉/dl, protein 1.1$\pm$0.1g/dl, fat 2.7$\pm$0.8g/dl, and lactose 6.3$\pm$0.3g/dl. No relationship existed between the intakes of carbohydrate, protein, fat and energy and the quantity and proximate composition of the milk. However, the intakes of energy, carbohydrate and vegetable protein were inversely related to the concentrations of energy and lactose in the milk. This result indicates that lactational capacity may be affected by the other factors excluding intakes of energy and energy-yielding nutrients and a high intake of energy may not guarantee optimal lactational capacity.

Objectives: This study was conducted to find out if the dietary iron intake of Koreans estimated by 2 different methods (iron content sources) using the food intake data from the Korea National Health and Nutrition Examination Survey (KNHANES) are comparable. One method was based on the KNHANES's Food & Nutrient Database (FND) derived mainly from the Korean Food Composition Table and the other used the iron content (IC) of food samples processed in the Korean Total Diet Study (KTDS). Methods: Dietary intake data from the 2013-2016 KNHANES was used to select representative foods (RFs) in KTDS for iron analysis. Selection of the RFs and cooking methods for each RF (RF × cooking method pair) was performed according to the 'Guidebook for Korean Total Diet Studies' and resulted in a total of 132 RFs and 224 'RF × cooking method' pairs. RFs were collected in 9 metropolitan cities nationwide once or twice (for those with seasonality) in 2018 and made into 6 composites each, based on the origin and season prior to cooking. Then, the RF composites prepared to a 'table ready' state for KTDS were analyzed by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). Dietary iron intake of the Korean population was estimated using only RFs' intake data based on the 2 sources of iron content, namely FND-KNHANES and IC-KTDS. Results: RFs in KTDS covered 92.0% of total food intake of Koreans in the 2016-2018 KNHANES. Mean iron intake of Koreans was 7.77 mg/person/day by IC-KTDS vs 9.73 mg/person/day by FND-KNHANES. The major food groups contributing to iron intake were meats (21.7%), vegetables (20.5%), and grains & cereals (13.4%) as per IC-KTDS. On the other hand, the latter source (FND-KNHANES) resulted in a very different profile: grains & cereals (31.1%), vegetables (16.8%), and meats (15.3%). While the top iron source was beef, accounting for 8.6% in the former, it was polished rice (19.2%) in the latter. There was a 10-fold difference in the iron content of polished rice between 2 sources that iron intakes excluding the contribution by polished rice resulted in very similar values: 7.58 mg/person/day by IC-KTDS and 7.86 mg/person/day by FND-KNHANES. Conclusions: This study revealed that the dietary iron intake estimated by 2 different methods were quite comparable, excluding one RF, namely polished rice. KTDS was thus proven to be a useful tool in estimating a 'closer-to-real' dietary intake of nutrients for Koreans and further research on various nutrients is warranted.

Numerous studies on the ablactation have been reported since Jundell’s report in 1924. This paper deals with the comparison in nutritional values, composition, economical sense and recommended dietary allowances to Korean infants of the weaning foods sold in Seoul, Jeonju and Gunsan together with the analysis of nutritional compositions of the most recommendable weaning food among those investigated. The results obtained from this study were; 1. Among ten kinds of the weaning foods produced in Korea, only nine sorts could be purchased in Seoul, seven in Jeonju and five in Gunsan. 2. It was difficult to compare directly the compositions of the weaning foods each other because of the differences of the unit indicated. 3. Not only the price of the same product in the same area was differentiated by 10 to 100 won but also the standard of nutritional composition was not identically indicated by the company produced. 4. Since the amount of directed dietary intake was much more than the actual nutritional requirements of Korean infants, waste of money was considered, if used according to the directions. 5. The nutritional compositions of the most recommendable weaning food among those investigated were indicated in Table. 6. More nutritious and economical weaning food adequate to Korean infants must be developed through further scientific, in vivo experiments.
