A survey was conducted on 500 women who were in their 20s to 40s and resided in North Gyeongsang Province including Daegu and Pohang from August 1 to September 28, 2012. And the answer sheets from 485 respondents were analyzed. The questionnaire used in this study covered skin type, dietary habits, life habits and food preference. After six food groups were selected, their preference for the food groups were analyzed, and the foods were classified again into three according to their preference. By age, the women who were aged between 40 and 49 made up the largest age group(30.3%), followed by the 30-39 age group(29.7%), those under the age of 25(24.5%) and the 25-29 age group(15.5%). As for preference for cereals, the women who were under the age of 25 had the strongest preference for cereals, and those aged between 40 and 49 had a less liking for cereals than the other age groups. The younger women showed a more preference for bread and rice cake. The women who were aged between 25 and 29 had the biggest preference for meat, fish, milk, dairy products and beverages, and the older women had a greater liking for vegetables and fruit. Concerning the skin type of the women in their 20s to 40s, a combination skin was most common, followed by a dry skin, normal skin and oily skin. The women who had a combination skin preferred bread, rice cake, milk and dairy products. Regarding ways of improving the skin, the women who were under the age of 25 were more concerned about cleansing, and those who were aged between 30 and 39 were more careful about the choice of cosmetics. The women whose skin was sensitive preferred vegetables and fruit, and many of those who ate lots of meat had an oily skin. The women with a combination skin were fond of spicy food, and those with an acne skin liked sweet taste. Those who had an acne skin perceived that drinking exerted a great influence on the skin, and many of the women who ate a lot of food, four cups of water or more per day, had a combination skin. The findings of the study suggest that the health of the skin is closely bound up with diet, namely the choice of food, and that the choice of food exercises an influence on the change of the skin and the maintenance of beautiful skin.
