The daily caffeine intake from elementary school children's favorite foods was surveyed and evaluated. Children may respond to caffeine differently from adults because they have different physiological makeup and are functionally immature. Therefore, caffeine exposure may have more serious consequences for children than for adults, irrespective of sensitivity. Their preference, perception, and intake of caffeine from children's favorite foods were investigated by questionnaire for 355 children. The order of children's preference over foods containing caffeine was ice cream and ices, confectionary, milk and milk products, and soft beverage. The daily caffeine intake of children was estimated to range from 0.16 to 917.28 mg/day, with an average of $36.04\;{\pm}\;82.7$ mg/day and $36.9\;{\pm}\;96.0$ mg/day for boys and girls, respectively. The daily caffeine intake according to body weight was $1.08\;{\pm}\;2.23$ mg/kg and $1.12\;{\pm}\;2.66$ mg/kg for boys and girls, respectively. The percentage of acceptable daily intake (ADI) of caffeine was 43.4% for boys and 44.9% for girls. The sources of caffeine for boys and girls were soft beverage (18.3 mg and 16.1 mg), milk and milk products (8.9 mg and 8.5 mg), ice cream and ices (5.7 mg and 7.3 mg), chocolate (1.6 mg and 3.2 mg), and confectionery (1.6 mg and 1.8 mg).

As the elderly population has increased in the advanced countries, food intake, relationship of nutrient intake and disease has become major problem in the aged. To investigate the dietary behaviors and the preference of food of the elderly for developing meal planning, the study was conducted through survey questionnaires including 24-hr dietary recall, dietary behaviors, food preference and frequency of food intake to 352 elderly (104 male and 248 female) who were more than 60 years old and living in Seoul. Most of subjects ate three meals regulary and the most preferred taste was sweet and the less preferred taste was sour. Dietary behaviors according to educational level were shown that the skipping meal time and duration time of one meal were significant difference in educational level. Most of the elderly subjects like kimchi and soybean paste soup. The more educated elderly were preferred milk. The reason of dislike of milk was bad flavor and diarrhea. Most of them who graduated from university and high school selected fishes because of good for health primary, otherwise no educated, elementary school and middle school graduated elderly selected vegetables primary. Meats, fishes, seaweeds, mushrooms, fruits, milk and milk products, eggs and vegetables intakes of total elderly subjects were significantly positively related to educational level. With respect to milk and milk products intakes, cheese, yogurt (curd) and milk intake of elderly was significantly negatively related to age. Therefore education for developing desirable dietary behaviors and improving the meal patterns should be in forced to elderly, especially who had poor educational background in order to manage the meal planning and to care for their health in the later life.

This study investigated the effects of a healthy image on the preference and intake frequency of meat and animal products. The study looked into beef, pork, chicken, sausage, mackerel, cutlass fish, croaker, tuna, squid, shrimp, clams, fish cakes, eggs, milk, yogurt, ice cream, and cheese. A total of 359 usable surveys given to elementary school students, college students, and adults were collected using a convenient sampling method. While milk had the healthiest image, sausage had the least healthy image. The respondents preferred yogurt the most and sausage the least. The intake frequency of eggs was the highest and clams the lowest. The healthy image, preference, and intake frequency for all studied foods showed significant differences across both gender and age. The relationship between healthy image and preference was significant for all foods, and a healthy image always had a positive influence on preference. The relationship of healthy image and intake frequency was significant in 14 foods except for mackerel, cutlass fish, and tuna. Also a healthy image created a positive effect on the intake frequency of 14 foods.

The purpose of this study was to provide the guidelines for the dietary lift by analyzing and studying the dietary behavior and food preference based on the gender. In the questions whether students' food preference is similar to their parents' or not, girls answered their food preferences were similar to them (M = 3.36), but boys not (M : 2.90). In the question if the knowledge learned in school has an effect on the choice of food, girls and boys answered it did not affect them, but there was a slight difference according to the gender; boys(M = 2.54) were under less influence than girls (M = 2.88). According to the gender, there was a meaningful difference in the food preference in meat, eggs, fish and shell, beans, milk and milk products, anchovies, fruits, fats and oils, beverage, and processed food. School education had a little influence on the habits of dietary life, only 8.0%. So more practical nutrition education was needed.

This study was carried out to investigate the effects of Bifidobacteria growth promoter BE0623 and a dietary fiber supplement, which included Bifidobacterium lactis BB12, Lactobacillus acidophilus, Streptococcus thermophilus, and Bifidobacterium lactis. In fermented milk containing BE0623, the viable cell count of Bifidobacteria significantly increased by about 45 to 75 times compared to the control, and the titratable acidity increased, whereas the pH decreased. All fractions obtained by isolating BE0623 had Bifidobacteria growth effect. Acacia dietary fiber is a pale yellow powder. It has a viscosity of 60 to 100 cPs and a pH between 4.1 and 5.0. Its general components are less than 10% moisture, more than 90% dietary fiber, and less than 4% ash. The optimal addition ratio of Bifidobacteria growth promoting material was determined to be 0.05%. The general components of the manufactured fermented milk were carbohydrate 17.85%, protein 3.63%, fat 3.00%, and dietary fiber 2.95%. During storage of the fermented milk for 24 days, its titratable acidity, viscosity, and sugar content all met the criteria. In addition, the viable cell counts of Bifidobacteria and lactic acid bacteria in the fermented milk were 1.7 × 10⁸ CFU·mL^-1 and 1.5 × 10⁷ CFU·mL^-1, respectively, and Escherichia coli was negative. There was no significant difference between the control group and the treatment group in the sensory evaluation of sweet, sour, weight, and flavor, and the preference for the treatment group was excellent. The acceptability of the fermented milk of the treated group according to the storage period was excellent in terms of color, flavor, and appearance.
