Ultra-processed foods, falling under group 4 of the Nova classification system, are manufactured from processed food ingredients such as oils, fats, sugars, starch, and protein isolates, containing minimal to no whole food. They commonly incorporate flavorings, colorings, emulsifiers, and various cosmetic additives to enhance their palatability. Ultra-processed foods have become increasingly prevalent in contemporary society owing to their convenience, affordability, extended shelf life, and enhanced taste and aroma through additives. This surge in the consumption of ultra-processed foods has sparked discussions regarding its adverse health effects. Numerous studies have highlighted that an increased intake of ultra-processed foods elevates the risk of metabolic disorders, such as cardiovascular diseases, obesity, and diabetes, along with an increased risk of various cancers. Moreover, its association with an increased mortality risk underscores the importance of recognizing that opting for these foods based solely on taste and convenience is risky. Thus, by recognizing dietary habits as modifiable factors that can prevent health issues, maintaining a balanced diet with diverse nutrient intakes is crucial for overall health. Therefore, raising awareness and understanding of ultra-processed food consumption can significantly contribute to promoting healthy lifestyles.

Recently, we found and analyzed vitamin $B_{12}$ in some Korean traditional plant foods which had not reported, yet. This study was to investigate vitamin $B_{12}$ intake and its dietary sources and the vitamin $B_{12}$ status in the very old elderly Koreans. We measured serum vitamin $B_{12}$ level and estimated the amounts of vitamin $B_{12}$ intake from different dietary sources in female elderly Koreans aged 85 and over who had consumed a relatively low animal traditional diet for the whole life. The average age of the subjects (n = 127) was 98.0 years (85-108 years). The assessment on energy and nutrient intake involved a one-day 24-hour recall, and serum vitamin $B_{12}$ concentration was measured by radioimmunoassay. Overall diet pattern was not different between the 85-99 yr-old group and centenarians, except centenarians were taking more dairy product. The average ratio of plant food to animal food consumption was 87.5:12.5 in weight. The average vitamin $B_{12}$ intake of our subjects was 3.2 ${\mu}g$, and 52.7% of subjects consumed under estimated average requirement, 2.0 ${\mu}g$/day. On dietary source, 67.3% of dietary vitamin $B_{12}$ was from meat, eggs and fishes and 30.6% was from plant foods, such as soybean-fermented foods, seaweeds, and kimchi. The average serum vitamin $B_{12}$ concentration was 450.5 pg/mL, and low serum vitamin $B_{12}$ (< 200 pg/mL) was found in 9.6% of subjects. Dietary vitamin $B_{12}$ intake was significantly lower in subjects with low serum vitamin $B_{12}$ (0.79 ${\mu}g$/day) than those with normal serum vitamin $B_{12}$ (3.47 ${\mu}g$/day). There were no significant difference in vitamin $B_{12}$ intake and its dietary sources and serum vitamin $B_{12}$ level between the 85-99 yr- old group and centenarians. In conclusion, several plant-origin foods including seaweed, soybean-fermented foods, and kimchi, may contribute significantly to good vitamin $B_{12}$ status in very old elderly Koreans.

Aspects of health food intake were investigated by conducting a questionnaire survey with over 480 of adults in Taejon and the data were analyzed by $\chi$$^2$-test, t-test and ANOVA, using an SAS program. Eighty two percent of the subjects had taken some kind of health food. The health foods they took frequently were, for example, health drinks, green tea, ginseng products, dietary fiber drinks, honey, general tea, vitamin B, vitamin C, and tonic medicines. The main reason for taking health foods was recovery from fatigue and the frequency of taking health foods was one time per day. Most of the subjects took health foods without knowledge of their components or effects. When they health foods with a perceived knowledge of their components and effects, they responded that the health foods were very helpful for them. Twenty percent of subjects experienced side effects, such as diarrhea, stomachache, headache, nettle rash, and stomach cramps. Information on health foods was obtained mainly from friends or family. The user group showed higher intention to continue health food intake than non users(p < 0.001). Health foods were taken without any knowledge about them. Health food intake was significantly correlated with consideration of disease, suffering or disease, medical examination, and self-perceived health status, but not with food habits and health food knowledge. As for the results from the adults consumption pattern of health food, an education program should be developed to choose proper health foods according to the consumers dietary life and health conditions. Also a proper guide line should be established to be chosen the authorized health foods.

In experiment 1, dietary self-selection of the 3 macronutrients, protein, fat, and carbohydrate were examined in male rats given 3 food cups of 80% carbohydrate, 80% protein, and 70% fat diets simultaneously. All the rats showed normal growth pattern and organ weight, which means they have ability to select just right kinds and amounts of nurients in order to support their growth and development. Mean values of caloric intake, body weight gain, serum lipid values and empty carcass compositions were not significantly differ between the upper and lower quartile groups of fat proportion of empty carcass compared to the lower quartile group(LF). Same feeding design was employed in experiment 2 where the effect of mild electric stress on food selection was studied. The rats in both control and electric stress group revealed a normal growth curve and organ weights. The rats in both control and electric stress group revealed a normal growth curve and organ weights. The stress group showed higher caloric intake and body weight gain than control group, but no significant effects of stress on serum and empty carcass components was found. Even though normal rats seemed to select macronutrients according to their physiolosical needs, there were individual differences in food selection whether they were exposed to stress or not. Therefore life long individual food selection pattern may have a great influence on nutritional status and chronic degenerative diseases of eldery, and on aging process.

This study was peformed to evaluate the served menu and investigate the management of food service in Korean Buddhist temples. Among the available temples in the nation, 34 temples were carefully selected considering practice type, location and the gender characteristics. A survey about meal preparation and management was conducted to the cooking staff in each the temple using questionnaire by interview between Jan 2004 and Aug 2004. The menus over A five consecutive days menu was were also collected for analysis to analyse. Civilian cooking staffs were preparing meals in 23(67.6%) of the temples and the proportion 18(52.9%) of the temples were planning their own the menus was 52.9%. Most kitchens in the temples were equipped with modernized kitchen appliances. The major food supply was the conventional market Even though the majority of the temples were using processed food, Korean fermented sauces as the most traditional temple food products were prepared by themselves. There were 114 menu patterns and the most frequently served meal pattern was ${\ulcorner}Rice+Soup+Kimchi+3{\sim}4\;side\;dishes{\lrcorner}$. Analyzing from the cultural characteristics point of view, the most frequently served dish type was 'Korean'(90%), while other types were 'modified Korean'(3.7%) and 'Western'(2.7%). The varieties of Various 438 different dishes provided were 438 provided and with Kimchies (19.8%), Seasoned vegetables(16.8%) and Rice(11.0%) being the highest were high in frequency when dishes were categorized into dish classes. Among the main dishes, the frequency of gruel(13.7%) was relatively high. These results suggest the need to conduct Based upon the results found, it was required to continue further research about preserving and inheriting the originality and uniqueness of the temple food.

A variety of studies show that a centraized rather than a generalized pattern of subcutaneous fat distribution is more directly associated with disorers of carbohydrate and lipid metabolism, as possibly hypertension, This study was an attempt to observe the relationship of body fat distribution, blood lipids, blood pressure and exercise in 85 healthy men and women. Within this group there was a gradation of fat distribution progressing from LBSO and UBSO defined on the basis of WHR. This paper reports the relationship of body fat distribution defined by WHR to plasma glucose, lipids, blood pressure, and exercise in this population. Although the obesity indices(RBW and BMI) were slightly higher in the UBSO group, significant differences existed between UBSO and LBSO groups with respect to WHR blood pressure, and total cholesterol concentration in female. WHR values were substantially different and this was primarily due to greater degrees of differences in waist as opposed to hips circum ference. Although no significant differences existed between UBSO and LBSO groups with respect to age, body weight, and hips circumference, energy intake, total cholesterol, LDL-cholesterol and WHR values were substantially different in male. Positive, significant correlations were found between WHR and both systolic and diastolic blood pressure and between WHR and the total plasma cholesterol concentration and age. When 26 pairs of exercise and nonexercise groups were matched according to sex, age and body weight, blood pressure and blood lipids were significantly lower in the exercise groups than those in the nonexercise groups. In conclusion, these findings suggest that an altered blood lipid profiles will manifast in men and women with upper body obese. Furthermore these findings suggest that exercise and physical activity may be beneficial for controlling blood lipids and blood pressure in healthy adults.
