Korean men in their 30s and 40s live on soju (rice liquor) and fresh bacon while Korean women live on ramen, instant noodles, and coffee, a study has found.

According to a report released Tuesday by the Korea Health Industry Development Institute under the Ministry of Health & Welfare, men aged 30 to 49 get most of their calories in the summertime from rice, followed by soju, ramen, pork and fresh bacon. The study was conducted on 983 households and 2,454 individuals nationwide, from June 27, 2005 to July 15.

According to the study, women in the same age group got most of their calories from rice, followed by ramen, pork, coffee and noodles. For men, the average intake per day in 2005 was 2400 calories.

Men in their 30s and 40s attained 814 calories or 33.9 percent of their daily intake from rice. A further 128.7 calories or 5.3 percent was attained by soju, 84.7 calories or 3.5 percent by ramen, 77.2 calories or 3.2 percent from pork and 61.5 calories or 2.5 percent from fresh bacon.

Women attained a similar amount of calories as men from rice, ramen, and pork, but instead of soju they attained an average of 38.7 calories per day from coffee.

The average coffee mix has 55 calories. Dr. Jang Young-ae of the Korea Health Industry Development Institute said, "Soju is the second or third largest energy supplier for men over 30. The same result was found from 1999 to 2005."
