This qualitative analysis was conducted to analyze the effects of teeth and eating foods in the elderly on their subjective happiness based on a focus-group interview (FGI). The study subjects were 10 people over 65 years old who visited a social welfare center in D City and agreed to participate in the study. One group consisted of five members and FGIs were performed for about 40 minutes per group. Based on the study results, five topics were evaluated, status of teeth, methods of dental health control, inconvenience within mouth, eating foods, and eating foods and subjective happiness. The study subjects answered that they felt distressed and annoyed if they could only see, but not eat favorite foods and that this made them feel old. One respondent even mentioned it made them want to stop living. Based on the results of this study, it is necessary to develop customized dental health control programs by age, gender, income level, education level, and health status, and to build the specialists.

The purpose of this study was to find out the common characteristics of eating behaviors of the long-lived elderly in order to offer the basic data for establishing dietary guidelines for a long and healthy life for the general population. The subjects were three-hundred elderly people over age 85 living in Kyungpook Sung-ju who have no problems in daily living. The general characteristics, nutrition knowledge and attitudes, meal patterns, and food preferences of the subjects were surveyed by individual intervies. The levels of the nutrition knowledge of the subjects were very low(average score ; 4.3) and the correlation coefficient between their nutrition knowledge and attitude score was also low(r=0.323, p=0.000). Most of the subjects(93%) had a regular meal pattern consuming three meals a day. The major staple food was rice mixed with other grains(75%) and the number of side dishes was mostly under four(99%). A majority(73%) had no habit of overeating and 51% of the subjects were taking snacks besides regular meals. Thirty one percent of the subjects had drinking habits and 80% of the drinking subjects had over 40 years of drinking history. The most common frequencies for intakes of various food groups were ; more than once a day(95%) for vegetables ; 2∼3 times a week(74%) for green and orange color vegetables ; 2∼3 times a week(72%) for fruits ; once a day(70%) for fish, eggs and legumes ; 2∼3 times a week(49%) for milk ; 2∼3 times a week(72%) for fruits ; once a day(70%) for fish, eggs and legumes ; 2-3 times a week(49%) for milk ; 2-3 times a week(85%) for seaweeds and 2-3 times a week(81%) for foods cooked with oil. The most preferred foods by the subjects were white rice(staple foods), soybean paste soup(soups), beef and eggs(meats and eggs), yellow croaker and hair tail(fish and shellfish), yoghurt(milk and milk products), all vegetables except carrot(vegetables), and watermelon(fruits). The popular food preparation methods included mixing with seasonings and the most preferred taste was sweet. The results showed that the eating pattern of long-lived elderly was characterized by regularity, simplicity, and no overeating.

This study aim to evaluate dietary quality and nutritional status according to the consumption of health functional food using Nutrition Quotient for Korean elderly (NQ-E) for 288 elderly people attending senior welfare centers in Gyeonggi-do. The questionnaire consisted of items about general information, health functional food, and Nutrition Quotient for Korean elderly (NQ-E). Chi-squared test, Fisher's exact tests, and Analysis of Covariance (ANCOVA) were performed using the SAS program ver. 9.4. Among the male and female subjects, the female subjects consumed more health functional food. The results of the dietary quality and nutritional status difference according to the intake of health functional food showed significant differences only in the areas of variety and abstinence among nutrition quotient factors for men, while no significant differences were observed in any of the nutrition quotient factors for women. In conclusion, focused-nutrition education program and useful guideline is needed for promoting adequate consumption of health functional foods in elderly.

Sodium is a necessary element for the body. Excessive intake of sodium is known as one of the risk factors for chronic diseases. Recently, increasing numbers of people in Korea are suffering from chronic diseases. Major causes of deaths were chronic degenerative disease with the rising aging population. Especially, the population of rural areas is growing older fast. In rural areas, it is known that under nutrition and high sodium intake were major nutritional problems. For sodium intake, there were some studies about contributing food items. They were not enough to show diets relate to sodium intakes. Thus, this study analyzed dishes contributing to sodium intakes of elderly living in rural areas. Dietary intakes using "the 24hour recall method" were used. For the analysis for sodium intakes, "Can-pro3.0" was used. Ranking of dishes by contributions of sodium intakes were Korean cabbage, kimchi (19.6%), seasoned soybean paste (5.3%), soybean paste (4.6%), soybean paste soup dried radish leaves (3.5%), hot pork and kimchi stew (3.4%) in order. Ranking of dish groups by sodium intakes was kimchies (28.3%), soup and hot soups (22.8%), stews and casseroles (9.7%), seasonings (8.2%),and seasoned vegetables (6.0%) in order. One-dish meals among cooked rice, wheat noodles among noodle and mandu, soups using the soybean paste, stews using soybean paste and kimchi, salted fish among grilled foods, stir-fried anchovy among stir-fried foods, seasoned spinach, and Korean cabbage kimchi contributed to sodium intakes. As the nutrition deficiency of the elderly living in rural areas could be a problem, and excessive sodium intakes is threatening to their health, it is needed for the senior citizens to have adequate knowledge for diets containing less sodium. And recipes for healthy food and nutrition education based on their diets are needed.

Our society is aging rapidly, and the number of elderly people who are in charge of purchasing and preparing foods at home is increasing. However, most the elderly have difficulty managing nutrition and food safety by themselves. The purpose of this study was to develop the necessary knowledge, through focus group interview and Delphi technique to establish a food safety and nutrition education program. The diet and educational needs of the elderly were surveyed through FGI. The education topics were decided by the Delphi technique. The education program consisted of a five week program, and the topics taught were 'Dietary Change for Healthy Life', 'Prevention of Food Poisoning in Everyday Life', 'Safe Food Handling for my Health', 'Healthy Dietary Life to Prevent Chronic Disease', and 'Safety! Nutrition! Healthy Dietary Life'. This education program was designed to decrease the perceived barriers, and to increase the perceived interests and the sense of self-efficacy. Education program materials, lesson plans, slides, handouts, videos, leaflets, and booklets were developed. Based on the results, the contents of the food safety guideline leaflets for the elderly were decided as the following: (1) wash your hands in the correct way; (2) select safe food; (3) cook foods safely; (4) keep foods safely; (5) keep kitchen utensils clean. In conclusion, if advanced education programs are implemented and delivered continuously in locations such as health centers and community welfare centers, those will contribute significantly to enhance the perception of food safety and to change the desirable dietary behavior of the elderly.

The purpose of this study was to define a one-portion size of food frequently consumed by the Koreans aged 65 years or over. From the original 8,631 people who took part in the Forth Korea National Health and Nutrition Examination Survey(KNHANES IV-2) 2008, we analyzed the data on 1,458 persons (16.9%) aged 65 and over, and selected food items consumed based on the intake frequency of 30 or more by all participant. A total of 158 varieties of food items were selected. The portion size of food items was set on the basis of the median amount (50 percentile) in a single intake by a single person. In the cereals category, 13 items were selected, of which the most frequently consumed item was well-polished rice with portion size of 75 g. Among legumes, 7 items were selected, of which the most frequent item was dried black soybean with a portion size of 6 g. Among the 16 groups, the most varied food group (49 items) was vegetables, and among these the most frequently occurring item was garlic (5 g), while among the fruit group, only 11 items were selected, as their intake frequency was low. Fish and shellfish were more frequently consumed by the elderly than meats. The most frequently consumed meat was pork loin, with a portion size of 30 g. In fish and shellfish, the most frequently consumed item was dried and boiled large anchovy with a portion size of 2 g. Portion sizes for food items consumed regularly by the elderly may be conveniently and effectively used in dietary planning and in nutritional education programs, and in assessing the diet intake status of the elderly.

The purpose of this study was to examine the characteristics of the dietary intake of Korean elderly according to chew-ing ability using data from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted during 2007-2010. Among subjects aged 65 years and over, more than half, 54.3% of elderly people, were classified as the difficulty in chewing group (DC). The DC group had lower nutrients and food intakes than those of in the no difficulty in chewing group (NDC). Findings showed that subjects in the DC group consumed fewer foods, especially fruits and vegetables. In addition, the DC group had significantly lower intakes of pan-fried food, stir-fried food, braised food, and seasoned-cooked vegetables, which could not be easily cooked or chewed. On the other hand, the number of soups and stews included in the top 30 largely consumed dishes were higher in the DC group than in the NDC group. No difference in numbers of daily meal/snack intake was observed between the two groups, however, the DC group had lower numbers of side-dishes compared to the NDC group. Fewer side-dishes per meal could be related to lower intakes of nutrients in dietary quality. Findings of this study demonstrated that dietary intake was influenced by chewing ability of elderly Korean people. Therefore, study of factors affecting dietary intake such as convenient cooking methods to decrease cooking time and skills to extend preservation and storage time of foods will necessary. In addition, development of food products and new techniques of cooking considering health status, chewing, and swallowing ability is required for the elderly, followed by establishment of standards for senior-friendly food products.

Fat consumption has decreased since the 1950's in the United States, and coronary heart disease mortality rates have gradually declined as well. These changes might be associated with changes of attitudes due to increased information about the relationship between fat consumption and hear disease. The purpose of this study was to determine whether knowledge and attitudes concerning fat and foods high or low in fat had an impact on peoples' actual fat consumption. for this study, the data of fat consumption and knowledge/attitudes of people came from the 1989-1991 Continuing Survey of food Intakes by Individuals/Diet and Health Knowledge Survey (CSFII/DHKS), conducted by USDA. It was found that women 65 years ed older tried to avoid more fat and consume more vegetables than those aged 25-64 years ; in fact, the actual fit consumption of those over 65 years was lowest among all age categories. However, the elderly did not have as much nutrition knowledge as people aged 25-64 years. Attitudes concerning vegetables and health were a better predictor of fat consumption than those concerning fat itself. However, low-fat milk consumption was influenced by nutrition knowledge as well as attitudes about fat intake people with better knowledge and attitudes concerning fat intake consumed more low-fat milk. This could be resulted from the reason that low-fat milk is a good substitute for whole milk. The conclusion of this study is that there are two essential elements in healthy eating patterns： a) good attitudes towards fat and vegetable consumption, and b) correct nutritional knowledge concerning the fat-content of foods and the availability of alternatives.

Nowadays, the nutritional deficits are rarely seen in Korea. However, an increased availability of the highly palatable energy dense, nutrient-poor foods increases the risks of obesity and deficits of vitamins and minerals in the general population. Also, optimum intake of vitamins and minerals, which varies with age and genetic back ground, might not suffice the poor, young, obese, and elderly people. Young girls and individuals participating in weight reductions and aesthetic components are prone to micronutrient deficiencies because they restrict food intake and specific micronutrient rich foods. An inadequate intake of vitamins or minerals is associated with reduced physical performance and exercise capacity, increased obesity, decreased cognitive function, increased DNA damages such as single- and double-stranded breaks or oxidative DNA lesions, and accelerated aging process and increased neuronal damages with mitochondrial oxidative decay. Most of these deleterious effects of the deficit could be prevented by a one tablet of multivitamins with a good balanced diet. High dose B vitamins are frequently administered to overcome the metabolic inadequacy to the people with the less functional enzymes with increased Km values for their coenzymes due to the single gene mutation or due to the single nucleotide polymorphisms. And some certain antioxidant vitamins are also used in large quantities to overcome the oxidative stress and to repair the damages. In this review, new nutritional concepts of some vitamins and minerals, which are widely used and useful for the children, will be discussed.

The purpose of this study was to estimate food intakes of the long-lived elderly and to obtain the data for establishing dietary guidelines that may be recommended for the general population for the sake of longvity. The subjects of the study were 224 elderly people of age over 85 years living in Kyungpook Sung-Ju area who have no problem in daily living. The food consumption survey was carried out seasonally by the repeated 24-hr recall method for one year. The subject group for this study was composed of 58 males and 166 females, the average age being 87 years old. Food intakes of the winter were more than any other seasons. The mean daily total food intake per capita was 594.4g, 513.5 g (86.4%) from plant foods and 79.3 g(13.3%) from animal foods. The sequence of high intakes of food groups were cereals, vegetables, fruits, fishes, legumes and meats. Boiled white rice, beef soup, soybean paste soup, soybean paste stew, broiled yellow croaker, kimchi, ra myon and broiled noodles were consumed most frequently. In conclusion, the subjects consumed much more plants foods than animal foods and consumed more natural and seasonal foods than processed foods and also showed food habits of eating small meals. Dietary habits of eating small meals containing abundant amount of fresh plant foods might partially contribute to the longevity of the subjects.
