Seven day's menus consisting of the Korean traditional dietary patterns were prepared according to the Korean nutrition allowances per capital of whole population. After cooking foods one day's meal was collected, homogenized for one week. Nutrients in each day's meal were analysed. The results of this analysis are as follows ; Lipids contents were about 23% higher than the data obtained nationwide nutrition survey conducted in 1984. This suggests the increasing tendency of the fat the oil consumption . PUFA ratio in lipid was 35%, that the customary Korean cooking include high confirmiry amount of vegetable oils. Daily tocopherol intake was 8.3mg . This results is believed to as one reference to set up Korean R.D.A for tocopherol.

Vascular dementia is the most common neuropsychiatric syndrome and is characterized by synaptic dysfunction, neuroinflammation, and cognitive dysfunction. Vascular dementia is associated with various environmental, genetic, and lifestyle risk factors. Recent research has focused on the association between vascular dementia and dietary patterns, suggesting that dietary regulation leads to better control of energy metabolism, improvements in brain insulin resistance, and the suppression of neuroinflammation. Intermittent fasting is a calorie-restriction method known to be more effective in promoting fat loss and regulating the impairment of glucose metabolism as compared with other dietary restriction regimens. Herein, the authors review the effects of intermittent fasting with regard to vascular dementia based on recent evidence and propose that intermittent fasting could be a therapeutic approach for ameliorating vascular dementia pathology and preventing its onset.

포도씨유의 생체 내 지질대사에 미치는 효과를 평가하고자 식이급원이 상이한 들깨유 및 옥수수유를 흰쥐에게 급여하여 체내 지질패턴 및 간조직의 지방산 조성을 분석한 결과는 다음과 같다. 일반식이군과 고지방 식이를 급여받은 쥐의 체중은 7주까지 꾸준히 증가하였다. 그러나 일반식이에 들깨유을 급여받은 쥐는 7주 후 체중이 감소하였고 다른 유지군을 급여받은 군들은 8주째부터 감소하였다. 식이섭취량 은 고지방 식이군 보다 일반식이군이 높았고 식이효율은 일반식이에 들깨유을 혼합하여 급여한 군에서 유의적으로 낮았다. 혈청 지질패턴 분석결과, 총지질 농도는 들깨유을 혼합한 일반식이군과 고지방 식이군에서 유의적으로 감소하였고 중성지방과 인지질 농도는 일반식이군에게 들깨유 급여시 유의적으로 낮았다. HDL-C은 일반식이군이 고지방 식이군보다 유의적으로 높게 나타났으나 일반식이군에 포도씨, 들깨유 및 옥수수유을 혼합하여 급여한 군간에 유의적인 차이는 없었던 반면 고지방 식이군와 들깨유을 급여한 군에서 HDL-C이 유의적으로 증가하였다. LDL-C은고지방식이군과 일반식이군간에 유의적인 차이가 나타났는데, 특히 고지방식이에 들깨유을 급여한 군에서 유의적으로 낮았고 포도씨유 급여군도 감소하는 경향이었다. HDL-ChDL-C 수치가 고지방식이 군에서 다른 식이지방에 비하여 PHF군에서 유의적으로 높았던 것은 혈중 지질패턴을유익하게 바꾸어준 결과이며, 이로 인하여 동맥경화인자인Al 지수가 CHF군에 비해 PHF군과 GSHF군에서 유의적으로 감소되었다. 간조직의 총지방, 총콜레스테를 및 중성지방 함량은 일반식이군은 들깨유군에서 가장 낮았고 그다음이 포도씨유군 및 옥수수유군 순으로 관찰되었다. 간조직의지방산 조성 분석결과 고지방식이군은 포화지방산은 감소하였고 단일불포화 지방산과 다가불포화 지방산은 일반식이군에 비해 증가하였다. 따라서 본 연구결과 유지 급원에 따라함유하는 지방산 조성의 비율도 달라져 식이 급원에 의해 생체내 지방산 조성에 큰 영향을 미치는 것으로 생각된다.

This study was carried out to compare the effect of smoking on dietary habits, nutrient intakes and blood lipid profiles in 173 adult male drinkers. Subjects were classified by two groups, alcohol-only and alcohol-smoking, based on their alcohol or smoking habits. The BMI of the alcohol-smoking group was significantly lower than those of alcohol-only group. In dietary habits, the alcohol-smoking group had higher irregular breakfast and dinner intakes than alcoholonly group (p < 0.05). Plant lipid intake of the alcohol-smoking group was higher than those of alcohol-only group (p < 0.05) and the vitamin C intake of the alcohol-smoking group was lower than those of alcohol-only group (p < 0.05). With regard to the diet quality evaluation of subjects, the alcohol-smoking group showed significantly lower values than alcohol-only group in the nutrient density of carbohydrate, dietary fiber, sodium, potassium, vitamin $B_6$, and vitamin C. Also, with regard to the index of nutrition quality (INQ) and the nutrient adequacy ratio (NAR), the alcohol-smoking group showed significantly lower value than alcohol-only group in vitamin C. With these results, we found that the alcohol-smoking group had lower diet quality evaluation. The results of blood analysis showed that HDL-cholesterol in the alcohol-smoking group was significantly lower than that in the alcohol-only group. In conclusion, the alcohol-smoking group had greater health risk than the alcohol-only group. Particularly, alcohol-smoking caused irregular eating patterns and unbalanced nutrition intakes compared to alcohol-only and also changed blood composition as shown in the decrease of HDL-cholesterol. Besides, the index of coronary heart disease such as AI was higher in both groups suggesting that alcohol-only or alcohol-smoking cause health problems. Since there is the limiting point in which the comparative analysis of non-drinkers and non-smokers is unable to be performed in this study, further wide research is needed on that matter.

This study was designed to investigate the effect of the ratio of energy from carbohydrate to total calories on dietary intake, obesity index, blood pressure, and blood lipid content in cardiovascular disease patients over 35 years old. A total of 552(227 male, 325 female) subjects were divided into three groups according to carbohydrate/total energy ratio : carbohydrate ratios below 25 percent were in the low carbohydrate group( <61.1%), between 25 and 75 percent carbohydrate were medium($\geq$61.1-<74.7%), and higher than 75 percent were in the high carbohydrate group($\geq$74.7%). The anthropometric data, nutrient intake, serum lipid levels, and blood pressure of each group were compared with one another. For men and women with high carbohydrate intakes, Inadequate nutritional intake was observed. Abdominal fat accumulation and blood TC level for men in the high carbohydrate group were higher than in medium or low carbohydrate groups. Therefore, it seems that high carbohydrate intake may produce adverse effects on abdominal fat accumulation and blood lipid patterns. Blood pressure, however, was significantly higher for women in low and high carbohydrate groups than in medium carbohydrate group. These results suggest that extremely high and low carbohydrate intake may raise the risk of cardiovascular disease and that it is necessary to consume nutritionally balanced meals. This can be done by controlling the ratio of dietary carbohydrate at a medium level in order to prevent and/or to reduce the risk.

This study was designed to investigate the effect of Ca supplementation of 1,000mg per day for 53 weeks on lipid, Na, and K metabolism and on blood pressure in postmenopausal women. The subjects were 12 healthy women aged from 60 to 70 years. They were divided into two groups : the placebo(control group) and the Ca supplemented(1,000 mg/day) group(Ca group). Metabolic studies were conducted twice in the 1st and the 53rd weeks. The results were as follows : Serum triglyceride, total cholesterol and LDL-choesterol levels tended to be decreased after the experiment. Serum VLDL-cholesterol lowering effect was observed with Ca supplementation(p<0.05), and also the significantly elevated HDL/(LDL+VLDL) ratio in Ca supplemented subjects whose average Na intake was as high as 4.9g per day. This phenomena was accompanied with increased Na retention and increased Na excretion in feces, but with decreased urinary Na in Ca supplemented group. However, considering much higher Na reteniton in the control group at the end of experiment(control va Ca ; 1272.3mg vs 732.9mg), Ca supplementation may have some beneficial effects on Na blance. Serum aldosterone level increased significantly in the Ca group after the exsperiment(p<0.05). With these normotensive subjects, there were no level increased significantly in the Ca group after the experiment(p<0.05). With these normotensive subjects, there were no pronounced effect of Ca supplementation on blood pressure, however, decrease in diastolic blood pressure were observed at the 14th week and end of the experiment(p<0.05). In summary, the Ca supplementation on postmenopausal Koran women appears to exert a desirables effect on blood lipid patterns related to the coronary heart diseases and to be beneficial in controlling diastolic blood pressure. Further studies with hypertensive or/and hyperlipidemic subjects are required to clarify the effect of Ca supplementation in Koreans.

In order to investigate the ramyeon intake patterns, food value recognition, and their effects on blood pressure and blood lipid levels, a total of 385 male students aged 13- 15 years living in rural area were sampled randomly, and they were surveyed using questionnaire. Blood pressure and fasting serum lipids levels of 123 subjects selected among the total were determined. Of the total subjects 80.3％ either liked or liked very much ramyeon and 42.2％ of them were eating ramyeon from 1 to 2 times a week,21.1％ 5-6 times a week, while 11.7％ more than once a day, and 13.1％ less than once a month. They took ramyeon from one (56.8％) to two (25.4％) packs each time. Two-third of subjects consumed entire ramyeon soup or more than half of it. Mostly they added egg or onion to ramyeon and took along with kimchi, cooked rice, danmuji, or dried laver. The food value recognition score about ramyeon was 41.33 out of 100 full grade. Comparing to underweight or normal weight subjects, overweight students tended to take ramyeon more frequently when playing with friends and tended to consume less soup of ramyeon. There was a significant negative correlation between ramyeon intake frequencies and HDL-cholesterol levels (r = -.223 p < .05). Moreover, among the normal body weight students (n = 72) adjusted with relative weight, ramyeon intake frequencies showed not only a significant negative correlation with HDL-cholesterol level (r = -.244 p < .05), but also significant positive correlations with atherogenic index (r : .249 p < .05) and systolic blood pressure (r : .259 p < .05) . These results suggested that frequent intake of ramyeon with limited sidedishes as a whole meal might have negative influences on blood pressure and serum lipid levels. Nutrition education is needed to have correct food value recognition and proper consumption of ramyeon along with the balanced diet. (Korean J Community Nutrition 8(4) : 485-494, 2003)
