  • 인간은 주로 식품을 통해 다이옥신에 폭로되는 것으로 알려져 있다. 그러나 우리 나라에서는 다이옥신의 섭취량에 대한 조사뿐만 아니라 일반 환경시료 중 다이옥신 잔류 농도에 대한 실태파악조차도 매우 적은 상황이다. 따라서 본 연구에서는 우리 나라에서 시판되고 있는 식품 중 다이옥신 잔류실태를 조사하고 이 결과를 이용하여 식품을 통한 1일 다이옥신 섭취량을 평가하였다. 10종의 식물성 식품과 9종의 동물성 식품을 대상으로 다이옥신 잔류 농도를 분석한 결과 다이옥신 농도는 0.02(우유)~5.39(멸치) pg/g의 범위였으며 TEQ농도는 0.0008~0.3153 pgTEQ/g의 범위로 개별 식품별 농도는 어패류, 육류, 채소류, 곡류, 과일류, 우유의 순으로 높게 나타났다. 우리 나라 국민의 1일 다이옥신 섭취량은 37.7 pgTEQ/day로서 우리 나라 성인의 평균체중 50kg을 기준으로 환산하면 약 0.75 pgTEQ/kg/day의 다이옥신을 섭취하고 있는 것으로 나타났다. 이들 수치는 외국에 비해 다소 낮은 수준이었고 어패류의 섭취가 다이옥신 폭로의 주요한 경로인 것을 알 수 있었다.

  • This study was conducted to investigate the preference and consumption status of non-alcohol and alcohol beverages of Korean and Chinese university students in the Jeonbuk area. Self-administered questionnaires were collected from 241 Korean and 198 Chinese students. Statistical data analysis was completed using SPSS v. 12.0. 'Water' was the most commonly consumed non-alcohol beverages by all Korean and Chinese students. The intake frequency of 'carbonated drink' (p<.001), 'fruits/vegetable juice' (p<.05), and 'vinegar drink' (p<.01) of Chinese male students was significantly higher than the Korean male students. The intake frequency of 'ionic drink' (p<.001; p<.01) of Korean male and female students was significantly higher than the Chinese male and female students. The intake frequency of 'fruits/vegetable juice' (p<.001), 'milk' (p<.01), and 'soymilk' (p<.05) of Chinese female students was higher than the Korean female students. For the choosing the non-alcohol beverages, the Chinese female students were more health-oriented than the Korean female students (p<.01). 'Beer' was the most commonly consumed alcohol beverages by the Korean male and female and Chinese male students whereas 'Wine' was the most commonly consumed alcohol beverages by the Chinese female students. The intake frequency of 'Soju' of Korean male (p<.001) and female (p<.001) students was higher than the Chinese male and female students. The intake frequency of 'Wine' of Chinese male (p<.05) and female (p<.001) students higher than the Korean male and female students. Compared with the Chinese female students, the Korean female students more funds have to spend, in order to buy alcohol beverages (p<.01). More 81% of the Korean male and 80% of the female students reported drinking alcohol in 'beer house' whereas 78% of the Chinese male and 65% of female students drunken the alcohol in the 'beer house' or at 'home' (p<.01; p<.001). In conclusion, a practically and foreigner-friendly alcohol policies of university should be devised to reduce the alcohol consumption of students and related problems.

  • Differences in dietary intake of Korean Americans (KA) by the length of residence in the U.S. were studied in relation to health and disease patterns in Michigan. Of 1860 questionnaires mailed, 637 (34.3%) responded with demographics, anthropometrics, self-reported disease patterns, lifestyle, and dietary patterns (93-item FFQ developed for KA). Complete responses were available for 498 people (263 men,253 women, aged 30-87 yr), who were then divided into three groups based on the number of years lived in the U.S.: 15y, 16-25y, 26y. Age-adjusted weight, height, BMI, and waist to hip ratio were within the normal ranges and did not differ among the three groups. Chronic diseases frequently reported in men and women (age-adjusted) included hypertension (14.4%, 14.1%), digestive diseases (5.4%, 8.5%), diabetes (3.6%,4.9%), and arthritis(3.3%, 12.5%), respectively. The length of residence in the U.S. was inversely associated with the age-adjusted prevalence of digestive diseases (12.4%, 6.5%, 0.4% in men, 13.0%, 11.7%, 0% in women). The length of residence was positively associated with health consciousness, receiving regular health care, taking supplements regularly, and exercising, while inversely related to smoking. The majority favored American foods for breakfast and Korean foods for dinner. Foods frequently consumed included cooked rice (w/other grains). kimchi, coffee (w/cream and sugar),bread (white and dark), citrus juice, milk (low fat and skim), lettuce and cucumber, apple, seaweed, and soda. Intake frequency of the Korean starch food group was inversely associated with the length of residence for both men and women (p<0.001), but not with the American starch food group. Fat intake did not differ by the length of residence in the U.S. The dietary changes were associated with the length of residence and chronic disease patterns for the first generation of KA, which should be further examined 'for the subsequent generation of KA.

  • Long-chain (LC) n-3 polyunsaturated fatty acids (n-3 PUFAs), in particular docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), are nutrients involved in many metabolic and physiological processes, and are referred to as n-3 LCPUFA. They have been extensively studied for their effects in human nutrition and health. This paper provides an overview on metabolism, sources, dietary intake, and status of n-3 LCPUFA. A summary of the dietary recommendations for n-3 LCPUFAs for different age groups as well as specific physiological conditions is provided. Evidence for n-3 LCPUFA in cardiovascular diseases, including new studies, is reviewed. Expert recommendations generally support a beneficial effect of n-3 LCPUFA on cardiovascular health and recommend a daily intake of 500 mg as DHA and EPA, or 1-2 servings of fish per week. The role of n-3 LCPUFA on brain health, in particular neurodegenerative disorders and depression, is reviewed. The evidence for beneficial effects of n-3 LCPUFA on neurodegenerative disorders is non-conclusive despite mechanistic support and observational data. Hence, no definite n-3 LCPUFA expert recommendations are made. Data for the beneficial effect of n-3 LCPUFA on depression are generally compelling. Expert recommendations have been established: 200-300 mg/day for depression; up to 1-2 g/day for major depressive disorder. Recent studies support a beneficial role of n-3 LCPUFAs in reducing the risk for premature birth, with a daily intake of 600-800 mg of DHA during pregnancy. Finally, international experts recently reviewed the scientific evidence on DHA and arachidonic acid (ARA) in infant nutrition and concluded that the totality of data support that infant and follow-on formulas should provide both DHA and ARA at levels similar to those in breast milk. In conclusion, the available scientific data support that dietary recommendations for n-3 LCPUFA should be established for the general population and for subjects with specific physiological conditions.

  • Among modern people's life-style, the lack of exercise and sleep is related to infertility. Underexercise accumulates damp-sputum, resulting in the insufficiency of essence. It also obstructs the creation of essence, leading to insufficient essence. Activities at night without sleep cannot create the condition to help the process of yin, causing the insufficiency of essence. Fast food is made from the cattle which are fed the feed containing growth hormone and antibiotics in large quantities. Growth hormone causes the process of yang excessively in human body, while antibiotic suppresses the process of yin, leading to excessive damp-heat and hyperactive ministerial fire. Antiseptic included in instant food hampers the process of fermentation, or yin, and inhibits the digestion mechanism, obstructing damp-heat and bringing about hyperactive ministerial fire. Intake of excessive flesh and meat gives rise to incomplete combustion and hinders the creation of essence, causing hyperactive ministerial fire due to the lack of yin. Milk suits the calf that has a rapid growth cycle. Milk intake by humans leads to the rapid process of yang and eventually hyperactivity of ministerial fire. The imbalance between yin and yang, with essence insufficent and ministerial fire hyperactive, causes infertility in three aspects. First, the lack of essence itself makes conception difficult. Secondly, damp-sputum resulting from ministerial fire obstructs the circulation of qi and blood. It also hampers the normal supply of qi and blood to the uterus. Thirdly, the excessive process of yang may result in infertility. Generally speaking, pregnancy starts with implantation. If the excessive process of yang is in progress in body, static condition needed for implantation cannot be maintained, leading to infertility.

  • Object : This paper is designed to inquire into the influence of eating habits on the emotion of modem people. Method : The methodology is used that searches for materials such as books and treatises on the relationship between eating habits and emotion. Result : Meat used for fast food comes from cows that are fed the feed containing growth hormone and antibiotic. Growth hormone extremely supplements fire or yang within the body while antibiotics undermines the process of yin, leading to an accumulation of damp-heat and inflammation of ministerial fire. Additives contained in instant foods also impinge on the process of yin, leading to poor digestion, damp-heat toxins and ministerial fire. Excessive consumption of meat results in incomplete combustion of fat and hinders the formation of essence. Subsequently, ministerial fire becomes hyperactive as a result of the lack of yin energy. Increased meat consumption in the human diet is coupled with unhealthy eating pattern in which people eat too much for dinner and too quickly. Eating too much disturbs digestion, making it slow and incomplete, leading to excess damp-heat conditions, insufficient amount of vital essence and eventually hyperactive ministerial fire. Milk is considered a catalyst of faster growth, making it suitable for calves. Milk intake rapidly increases the balance of yang and eventually cause hyperactivity of ministerial fire. Conclusion : It is estimated that the eating habits of modern people cause the process of yang, making them feel restless, impatient and aggressive.

  • Lactose intolerance is a pathophysiological phenomenon caused by a deficiency of the enzyme lactase present in human intestines. Changes in intestinal digestion and colon fermentation after the intake of lactose-containing products cause diarrhea and other clinical discomforts. Therefore, lactose intolerance can be easily ameliorated by consuming lactose hydrolyzed milk and dairy products. In the recent years, lactose-free dairy products have provided lactose intolerant consumers with several options, due to an improvement in the quality and an increase in the variety of products. Currently, the manufacturing of lactose-free products also represents the fastest growing sector in the dairy industry. This review, thus, aims to provide an overview of the current availability and prospects of lactose-free dairy products, and also discuss the potential benefits of the development of a variety of lactose-free dairy foods.

  • This study examined the lifestyle factors, dietary attitudes, food habits, and dietary nutrition intake of college students before and after nutrition education. A total of 44 college students were recruited and a questionnaire survey was conducted. Dietary nutrient consumption was obtained from the one day 24-hr recall. Scores on 'Concerns about health (p<0.05)', 'Regular exercise (p<0.01)', and number of steps (p<0.001) were significantly higher after-training. The dietary attitude (31.3 vs. 33.7, p<0.01) and food habits (53.5 vs. 59.7, p<0.01) were significantly higher after-training. The scores on 'Eating a lot of food that I want to eat is more important than nutrition (p<0.01)', 'I am interested in information on nutrition and health (p<0.01)', 'Have three meals a day (p<0.01)', 'Have breakfast regularly (p<0.01)', 'Drink milk every day (p<0.001)', 'Have fruits every day (p<0.05)', and 'Apply nutrition knowledge to daily life (p<0.001)' were significantly higher after-training. Among the nutrients intakes, the protein (p<0.05), vitamin C (p<0.01), and calcium (p<0.001) were significantly higher after-training. Nutrition education improved the lifestyle factors, dietary attitudes, food habits, and dietary nutrition intakes.
