The number of utilized nutrient-kinds (UNs) as an index that consumers understand and actually utilize is investigated, and the objectives are set to clarify the relationship among the number of UNs, dietary habits and health. The hypotheses that utilizing a higher number of UNs is related to better dietary habits and health, and that an appropriate number of UNs is related to the optimum dietary habits and health are tested. A questionnaire survey was conducted in November 2003 on male university students in Shiga Prefecture, Japan, the responses of 278 of these students being suitable for analysis. The results show that the higher the number of UNs, the better was the use of nutrition labeling in respect of the level of knowledge and attitude toward dietary habits. It was also clarified that increasing the number of UNs led to enhanced levels of behavior, condition and food consumption, as well as knowledge and attitude. In other words, the higher the number of UNs, the better the dietary habits and health. It is therefore suggested that the number of UNs would be useful as an index to reveal the qualitative aspects of nutrition labeling use.
We investigated the bacterial contamination of writing tools used in five facilities providing meals for school-children that were examined in 2003. Bacterial contmaination by Staphylococcus aureus (S. aureus), Campylobacter jejuni and Bacillus cereus (B. cereus) was respectively detected in the writing tools of four facilities (80.0%), one facility (20.0%) and three facilities (60.0%). The bacterial contamination of writing tools was further investigated in 12 more facilities in 2004. Escherichia coli (E. coil), S. aureus and B. cereus were respectively detected in the writing tools of six facilities (50.0%), ten facilities (83.3%) and five facilities (41.7%). Bacterial contamination of the fingers before and after writing records of the cooking process was also examined. E. coli was detected on the fingers, which had been washed with an antiseptic solution, before recording the cooking process, S. aureus was detected on the fingers after recording the cooking process, and B. cereus were detected on the fingers both before and after recording the cooking process. A questionnaire survey of basic hygiene management showed that, while both dietitians and cooking staff were uneasy about bacterial contamination of the writing tools, many of them did not disinfect these writing tools with an antiseptic solution.
Professional golfers travel extensively during the tournament season, making it difficult to maintain their health and physical strength. Such problems as menstrual disorders and low bone mineral density have been reported with female athletes, and the difficulty of maintaining a good physical condition has been pointed out. This study investigates the current condition of professional female golfers with regard to their physical health and eating habits as the first step in devising a regimen to improve their physical condition. A questionnaire survey of such aspects as physical characteristics, food intake frequency, health condition, and nutrition was conducted on 104 professional female golfers. A total of 60 responses (58%) were usable and demonstrate a deterioration of physical condition during the tournament season. The respondents also expressed a desire to acquire information about nutrition from a dietitian or doctor.
