In regularity of meal time, 56.3% of the subjects had meals regularly. The older people were significantly higher than the younger people at regular intervals of meal times (p < 0.0001). The majority of the subjects had appropriate meal amounts. 73.5% of the subjects had balanced diets. Unbalanced diet was higher in younger people than in older people. The highest frequency to dining out was once a month and the lower age was significantly higher than older age (p < 0.001). When dining-out, the most important criteria for selecting a meal was the taste of food. 62.4% of the subjects ate meat and greasy animal food more than once a week. The younger in age and higher in educational levels have increased meat intake frequency. In the eating methods of animal fat, 37.5% of the subjects were high by eating generally untouched.
