This study was carried out to compare the hair mineral status of obese, over-weighted and non-obese individuals, to gather basic data for customizing menu development and to create an education manual for the obese persons. Food preferences or various disease states could be suggested by different mineral patterns in TMA(tissue mineral analysis). The results indicated that Zn status was considerably lower in the obese individuals than in the non-obese(p<0.001) whereas hair Na(p<0.0001), K(p<0.01) and Fe(p<0.05) were at significantly higher levels in the obese individuals. The ratio of Ca/K(p<0.001) was significantly lower in the obese than in the non-obese. But the levels of hair toxic minerals such as Sb, As, Hb, Al et al. were not differ according to BMI groups. The obtained data demonstrate the changes of hair mineral content in both overweight and obese individuals thus suggesting metabolic mineral disturbance in those groups.

Present experiment was designed to investigate the effect of long-term ethanol drinking on the mineral contents on hair, liver, kidney and muscle tissues. Forty-five rats were divided into 2 experimental groups and a control group. The control group received tap water and the other 2 groups 4% and 25% ethanol respectively as drinking source for 28 days. All rats were dissected on the 29th day. Hair, liver, kidney and muscle samples were taken and analyzed for zinc, calcium, copper and magnesium contents by atomic absorption spectrophotometeric method. The results obtained are summrized as follows : 1) The zinc content of muscle in 25% ethanol group showed significant (P<0.01) decrease whereas that of hair in 4% ethanol group showed significant (p<0.1) increase. 2) The calcium content of hair in 4% ethanol group showed significant (p<0.1) increase whereas; that of hair, kidney and muscle in both group showed no significant difference. 3) The copper and magnesium contents of muscle showed significant (p<0.1, p<0.05) decrease in both groups. From these results it may be concluded that the long-term drinking of ethanol affects the mineral content of body tissue.

People with obesity or over-weight need nutritional intervention to reduce their weight, because weight loss reduces the incidence rate of chronic diseases such as hypertension, type II diabetes, cardiovascular diseases and cancer in obese people. This study was to develop a system for individualized weight control program available both for wired and wireless internet users. This system is especially useful to users carrying wireless internet mobile device. If they input their physical information (height, weight and waist circumference) and mineral levels measured by hair tissue mineral analysis, the system provides evaluation of their health status and metabolic related functions such as endocrine and carbohydrate tolerance. Based on these evaluations, food menus are then offered to them to manage their health status and to improve their metabolic related physiological functions in a personalized way. The system also provides more information for recommended foods, such as nutritional information, food ingredients, recipes, and videos related to cooking. Bibimbap was selected as an example dish for customized contents for mobile web. Bibimbap is one of the most well-known Korean traditional dishes prepared with various kinds of ingredients including several different kinds of vegetables, meat, and egg so that it is a low calorie dish as well as a well-balanced diet. Therefore, this system developed in this study allows the mobile users to access web site through wired wireless internet everywhere and provides a customized content to the users to manage their weight and finally to achieve a desirable weight.
