The National Health Insurance Corporation reported a 24.3% increase in young diabetes patients, rising to 3,564,059 in 2021 from 2017, which is attributed to factors like irregular eating patterns, heightened stress, and insufficient physical activity. Diabetes, which is increasing in all age groups, requires medication, regular exercise, and dietary management. Of these aspects, dietary therapy demands systematic management as it involves ensuring sufficient calorie intake and a balanced consumption of the three major nutrients. The current diabetes diet recommendations consider personal, health, social, and cultural factors, yet they fall short of addressing various health variables comprehensively. Therefore, this paper proposes a diet recommendation system using life log data from diabetic patients, which recommends customized dietary suggestions according to the individual's health status by considering multiple variables in the data.

The glycemic index (GI) and glycemic load (GL) have been considered risk factors for breast cancer, but association studies of breast cancer risk using simple GI and GL might be affected by confounding effects of the overall diet. A total of 357 cases and 357 age-matched controls were enrolled, and dietary intake was assessed using a validated food frequency questionnaire (FFQ) with 103 food items. GI and GL dietary patterns were derived by reduced rank regression (RRR) method. The GI and GL pattern scores were positively associated with breast cancer risk among postmenopausal women [OR (95%CI): 3.31 (1.06-10.39), p for trend=0.031; 9.24 (2.93-29.14), p for trend<0.001, respectively], while the GI pattern showed no statistically significant effects on breast cancer risk, and the GL pattern was only marginally significant, among premenopausal women (p for trend=0.043). The GI and GL pattern scores were positively associated with the risk of breast cancer in subgroups defined by hormone receptor status in postmenopausal women. The GI and GL patterns based on all food items consumed were positively associated with breast cancer.

Research on diet, acculturation, and ethnicity has suggested that immigrants dietary patterns differ from people who do not have immigration experience. The purpose of this paper is to present preliminary descriptive findings concerning consumption of foods that are common in Korean and American diets, by people of Korean descent residing in California. Adults (18 years of age or older, N=1334) of Korean descent who could be reached by listed residential telephone number in California were randomly selected and telephone-interviewed by closely supervised bilingual (Korean-English) interviewers who were specially trained for this task. This study found that dietary patterns of Koreans living in California differed according to age and gender; also, the frequency of consumption of foods differed according to number of years of residence and acculturation. Koreans who reported higher levels of acculturation to American society ate less of traditional Korean foods such as Kimchi and ate significantly more higher-fat foods common in the American diet. Increased acculturation was also related to an increased frequency of alcohol drinking. Older Koreans tended to eat slightly more of traditional foods such as rice, Kimchi, fruits, and fish, compared to younger Koreans. Women tended to eat healthier foods than men, consuming green vegetables, Kimchi, milk, cheese/yogurt, fruits, and bread more frequently. Koreans reporting longer residences in the United States reported a greater consumption of pork, bread, and soda.

BACKGROUND/OBJECTIVES: Relocation to new environments can have a negative impact on health by altering body weight and dietary patterns. This study attempted to elucidate changes in body weight, food security, and their current food and nutrient consumption in adult North Korean refugees (NKR) living in South Korea (SK). SUBJECTS/METHODS: This study analyzed data on 149 adult NKR from a North Korean refugee health in SK cohort at four time points (leaving North Korea, entering SK, first examination, and second examination). Body weight was self-reported at the two earlier time points and directly measured at the two later time points. Food security, diet-related behaviors (dietary habits and food consumption), and sociodemographic information were obtained using a self-administered questionnaire. Nutrient intake information was obtained by one-day 24-hour recall. Statistical analyses were performed with SPSS ver 23.0. RESULTS: Body weight increased during relocation by an average of 4 kg, although diversified patterns were observed during the settlement period in SK. Approximately 39.6% of subjects maintained their body weight between the first and second examinations, whereas 38.6% gained and 22.1% lost at least 3% of their body weight at the first examination by the second examination. Food security status improved from 12.1% food secure proportion to 61.7%. NKR showed generally good food and nutrient consumption (index of nutrient quality: 0.77-1.93). The body weight loss group showed the most irregular meal consumption pattern (P < 0.05), and eating-out was infrequent in all three groups. Consumption frequencies of food groups did not differ by group, except in the fish group (P = 0.036). CONCLUSION: This study observed considerable body weight adjustment during the settlement period in SK after initial weight gain, whereas food security consistently improved. More detailed understanding of this process is needed to assist healthy settlement for NKR in SK.

The purpose of this study was to investigate the relationship between physical activity, diet and mental health of elderly and to use the study as basic data for a program development for elderly. This was a secondary data analysis study using the 2015 National Health and Nutrition Survey and the study subjects included 1,484 individuals aged 65 and over. The results showed that depression and stress perception in young-old were higher than old-old's and the suicidal ideation rate of old-old was higher than young-old's. In case of eating patterns, 'poor eating' in old-old was higher than young old's. Regression analysis showed that middle-intensity physical activity and eating patterns were associated with mental health of the elderly. Based on the results, it is necessary to develop a differentiated nursing intervention program suitable for the elderly by age.

Purpose: This study analyzed the dietary patterns of Central Asian immigrant workers (Mongolia, Kazakhstan, Uzbekistan, and Kyrgyzstan) living in South Korea to determine the food acculturation and how their dietary practices have changed after immigration. Methods: Self-administered questionnaires were completed by 186 Central Asian immigrant workers living in South Korea. A food frequency questionnaire (FFQ) was used to obtain information on the consumption frequency of 22 food items before and after their immigration to Korea. Results: Central Asians switched to Korean meat consumption patterns, which consume mainly pork, chicken, and beef, showing a decrease in the intake of beef and lamb and an increase in that of pork. Their consumption of Namul (cooked vegetable), Kimchi, rice, and marine products increased while that of potatoes decreased during acculturation to Korean food culture. Positive changes were observed in Mongolians' eating habits. Their meat-based diet turned into a healthy one in which nutritional balance was achieved by consuming the various food groups. Negative dietary changes were also observed; intake of instant foods and coffee increased while black and green tea consumption decreased. Intake of Namul (p < 0.01), Kimchi (p < 0.01), rice (p < 0.001), ramen (p < 0.001), pork, chicken (p < 0.01), fish (p < 0.01), seafood (p < 0.001), and coffee (p < 0.001) increased significantly in the group that responded and their health improved after moving to Korea. This result suggests that health improved among those who were well settled in Korea and ate the various food groups. Conclusion: These findings can help understand the acculturation process to Korean food culture and provide a basis for developing policies to help them adjust to Korean food culture.

BACKGROUND/OBJECTIVES: Prior studies, mostly conducted in Western countries, have suggested that the low cost of energy-dense foods is associated with an increased risk of obesity. This study aimed to investigate the association between food costs and obesity risk among Koreans who may have different food cost and dietary patterns than those of Western populations. SUBJECTS/METHODS: We used baseline data from a cohort of 45,193 men and 83,172 women aged 40-79 years (in 2006-2013). Dietary intake information was collected using a validated food frequency questionnaire. Prudent and Western dietary patterns extracted via principal component analysis. Food cost was calculated based on Korean government data and market prices. Logistic regression analyses were performed to investigate the association of daily total, prudent, and Western food cost per calorie with obesity. RESULTS: Men in the highest total food cost quintile had 15% higher odds of obesity, after adjusting for demographic characteristics and lifestyle factors (adjusted odds ratio, 1.15; 95% confidence interval, 1.08-1.22; P-trend < 0.001); however, this association was not clear in women (P-trend = 0.765). While both men and women showed positive associations between prudent food cost and obesity (P-trends < 0.001), the association between Western food cost and obesity was only significant in men (P-trend < 0.001). CONCLUSIONS: In countries in which consumption of Western foods is associated with higher food costs, higher food costs are associated with an increased risk of obesity; however, this association differs between men and women.

It is already well known that many factors are involved in maintaining normal blood glucose level. The amount and components of meal are also thought to be some of the factors which affect the blood glucose and insulin levels. It is reported that as for Koreans sugar takes up over 75% out of 2,098 kcal, the average daily calorie intake per adult. It implies that Koreans take a high-sugar diet compared with Westerners who take $40\sim50%$ of sugar out of their total average daily calorie. For the purpose of studying diurnal variations in serum glucose, insulin and C-peptide of normal Korean adults based on ordinary Korean diet, we selceted 13 normal Korean male adults and divided them into two groups, Group I (7 persons) and Group II (6 persons). We put Group I on 3,100kcal and 75% sugar diet, and Group II on 2,100 kcal and 69% sugar diet per day for over 4 days. Serum glucose, insulin and C-peptide were checked every 30 minutes or every hour throughout 24 hours. Results are as follows: 1. As for serum glucose level, in the prep ran dial fasting state in the morning, $mean{\pm}S.D.$ of Group I was $91.1{\pm}8.2mg%$, while that of Group II is $82.5{\pm}4.4mg%$. Both groups showed peaks of increased glucose level at postprandial 1 hour after each meal. The peak returned to the level shown during the fasting state at postprandial 1 hour after breakfast while the relatively high glucose levels were maintained respectively even for 2 or 3 hours.after lunch and dinner. 2. As for serum insulin level, Group showed $mean{\pm}S.D.$ of $14.7{\pm}3.0{\mu}U/ml$ while Group II shows that of $7.0{\pm}2.6{\mu}U/ml$ in the fasting state. Group I particularly showed the largest peak from preprandial a half or one and half an hour to postprandial one hour of lunch, and made relatively small peaks $(47.7{\pm}10.8{\mu}U/ml)$ at postorandial 1 hour after breakfast and dinner. No such large peak was marked in Group II, though it showed relatively similar patterns of peak after each meal. 3. As for C-peptide, in the fasting state, Group I and Group II showed $3.50{\pm}1.85$ and $1.66{\pm}0.53ng/ml$ of $mean{\pm}S.D.$, respectively. Group II showed peaks parallel to those for insulin level. None out of seven in Group I showed expected increase in C-peptide based insulin secretion at a half or one and half an hour before lunch. On the contrary, C-peptide increased in 5 subjects out of seven in Group I at 11:00 p.m. when insulin did not increase. 4. According to the integrated concentration method for a measurement of 24-hour total. insulin secretion rate, the $mean{\pm}S.D.$ of Group I was $76.4{\pm}15.2$ U and that of Group II was $58.6{\pm}21.1$ U. The above results confirm that Koreans, when given ordinary diet of 2,100 kcal and 69%, sugar, show insulin secretion pattern essentially similar to that of Westerners. On the contrary, when they are put on a high-calorie diet of 3,100 kcal a day, 75% of which is sugar, insulin secretion can be increased before lunch without increase in blood glucose. These results implies that insulin secretion can be affected by some other factors. The observation that an increase in C-peptide after 11 : 00 p.m. independent of insulin level supports an assertion that insulin secretion and C-peptide secretion can be thought as being physiologically dissociable, and these changes of diurnal patterns in the levels of serum insulin and C-peptide are thought to be resulted from the large meal and high-carbohydrate diet.

This study was conducted to investigate the influence of laminaran from Eisenia bicyclis on serum lipid composition of rats fed high fat and cholesterol diets. Fourty male Sprague-Dawley rats weighing $70{\pm}2.5g$ of 4 weeks old were fed experimental diets for 6 weeks with high fat diet consisting of basal diet plus cholesterol (1%) and lard (10%) for the inducement of hyperlipidemia. The effect of laminaran supplements via drinking waters on serum lipid composition of rat were investigated for 5 weeks by administration of experimental diet group fed basal diet only as normal group, control group fed high fat diet, LL group fed high fat diet plus 0.25% laminaran containing water, and LH group fed high fat diet plus 0.5% laminaran containing water, respectively. As a results of experiments, it was found that LL and LH groups showed significant (p<0.05) decrease in body weight gain and liver weight as compared with control and it may caused by decreased FER. The weight of cecum and adipose tissue (EFP) of LL group showed a significantly (p<0.05) decreased patterns compared with control. It was also found that LL and LH diet groups affects the intestinal length and transit time of rat as significantly (p<0.05) increased in length of intestine and decreased in transit time. In addition, LL and LH diet groups showed a dramatic decrease in triglyceride, total and LDL-cholesterol, and significant increase in HDL-cholesterol compared with control diet group, by which results in decreased in AI. These results indicate that crude laminaran from Eisenia bicyclis has a strong hyperlipidemic and hypercholesterolemic activities in rat fed high fat and cholesterol diet.
