The World Economic Forum has included Water-Energy-Food among the three major risk groups in the world, and Water-Energy-Food is related to the development strategies of countries and the lives of their citizens. This study calculates the combined Water-Energy-Food use efficiency in China for 2011-2020 based on the SBM-Malmquist index. The results show that the overall combined Water-Energy-Food efficiency in China is low, but shows an upward trend. There is a clear variability in the combined Water-Energy-Food utilization efficiency in China, with an overall geographic distribution pattern of East > Middle > West. Only Beijing and Shanghai have reached the real above effective nationwide, and all other provinces have inefficiency between input and output. The Malmquist index of integrated Water-Energy-Food utilization efficiency is 1.136, with an up ward trend, and technical efficiency and technological progress lead the improvement of integrated Water-Energy-Food utilization efficiency in China at the sametime. The Water-Energy-Food issue should be raised to a strategic level as soon as possible, and policy support should be provided for its development. Each region should establish a cross-regional coordinating body to formulate targeted measures according to the province's food production and water distribution, so as to promote economic transformation from sloppy development to green development as soon as possible.
This study was conducted to assess diet-related health appraisal for cardiometabolic diseases of the college students in Gyeonggi-do. The survey data obtained by 21 questionnaire(6 general characteristics and 15 food behaviors) given to 90 students, 41 males and 49 females. The average age of the subjects was 22.2 years old for the male students and 20.9 years old for the female students(p<0.001). Among the subjects, 35 males and 47 females' height, weight and percentage of body fat were measured using bioelectrical impedance(Inbody 720). The average height, weight, Body Mass Index and percent body fat of the subjects were 175.7cm, 69.5kg, 22.4 and 16.9% for males and 162.0cm, 53.5kg, 20.4 and 27.7% for females, respectively (p<0.001). Male students had a higher prevalence of smoking compared with female students(p<0.001). Females had higher intake frequency of fruits than males(p<0.05). Males had higher intake frequency of fishes than females(p<0.05). Male students had higher number of side dishes at mealtime compared with female students. There were no difference between the sexes in intake frequency of dairy, ramyeon, rice with whole grain, 3-layered pork belly, processed meat, soft drinks, soy products and fast food. Also, there were no difference between sexes in number of vegetables per day, frequency of eating out, prevalence of eating kimchi at every meal. Cardiometabolic risks were calculated by 'Diet-related health risk appraisal'. Male students had higher cardiometabolic risks(hypertension, hyperlipidemia, diabetes, obesity, abdominal obesity) than female students(p<0.001). Appropriate nutritional education for college male students may help to prevent cardiometabolic diseases in the future.

From 2008 to 2013, the mussel Mytilus galloprovincialis were collected from a major area of mussel production (Changseon area), which is a designated shellfish-cultivating area for export, located on the southern coast of Korea. The samples were analyzed for mercury (Hg) using a direct Hg analyzer and for other metals, such as cadmium (Cd), lead (Pb), arsenic (As), chromium, copper, nickel, and zinc, using inductively coupled plasma mass spectrometry. The concentrations and bioaccumulation of the heavy metals were determined, and a potential risk assessment was conducted to evaluate their hazards towards human consumption. The concentration and bioaccumulation ratio of Cd were the highest of the three hazardous metals (Cd, Pb, and Hg). The concentrations of hazardous metals in all samples were within the limits set by Korea and other countries. The estimated dietary intake (EDI) was compared to the provisional tolerable daily intake (PTDI) adopted by the Joint FAO/WHO Expert Committee on Food Additives and the U.S. Environmental Protection Agency. The EDIs of all heavy metals tested for mussel samples ranged from 0.01 to 4.99% of the PTDI; the highest value was measured for As. The hazard index (HI) can be used to assess the risk of heavy metal consumption associated with contaminated food. The HI for all samples was far less than 1.0, which indicates that the mussels produced in the Changseon area do not represent an appreciable hazard to humans and are fit for consumption.
This study was to investigate the risk factors for the development of diabetes mellitus on healthy offsprings of Korea non-insulin dependent diabetes mellitus(NIDDM) patients. Forty four offsprings who have at least 1 parent with NIDDM and age, sex and body mass index(BMI) matched forty four healthy control subjects were collected for this study. BMI, skinfold thickness, waist/hip circumference ratio(WHR), fasting blood glucose, serum insulin, serum lipid profile, nutrient intakes and food behaviors were measured. There were no significant difference in BMI, WHR, fasting blood glucose, insulin, total cholesterol, triglyceride and daily nutrients intake between offsprings and controls. But skinfold thickness, LDL-cholesterol level and sweety food eating frequency were significantly higher in male offsprings than in male controls. And HDL-cholesterol was significantly lower in male offsprings than in male controls. Although there were no significant difference, offsprings had a overeating habit and ate more confectionery and greasy food than controls.

The effectsof garlic vinegar supplementation on body weight, blood blucose, and plasma triglyceride and cholesterol were investigated in streptozotocin -induced diabetic rats fed high-cholesterol(1%) diet for 4 wk. The garlic vinegar was made by fermenting 20% frsh garlic juice. There was no effect of garlic vinegar on body weight, plasma glucose or triglyceride concentrations in the diabetic rats. Plasma total -cholesterol concentrations were unaffected by garlic vinegarr supplementation. However, plasma LDL-cholesterol concentrations and atherogenic index were significantly lower in the diabetic rats supplemented with garlic vinegar diet than tin the cotnrol rats. The diabetic-rats supplemented with garlic vinegar not only had increased HDL-cholesterol levels but had decreased LDL-cholesterol. This alteration in the HDL/LDL-cholesterol ratio in the diabetic rats may decrease the risk of atheroscelrosis. Therefore, the over-all effect of garlic vinegar supplement may contribute to the antiatherogenic role in streptozotocin-induced diabetic rats.
This study was performed to study the effects of dietary factors on breast and cervical cancer incidence in female Koreans. The subjects were 60 breast and 109 cervical cancer patients recruited from five general hospitals in Seoul. Food intake, anthropometric measurement, and blood compositions were studied through personal interview and using medical records, from August 1991 to September 1992. Body weight, body mass index, triceps skinfold thickness and body muscle mass were at upper limit of normal value, which suggest that these patients had a tendency of overweight. The levels of hemoglobin and hematocrit of the patients were below the normal values. The values of serum protein, albumin, and calcium were in the normal range but close to the lower bound. Therefore the nutritional status assessed by blood composition seems to be marginal. The results of diet history showed that most of the nutrient intake of the subjects met with RDA. The fat intake were 22.9-36.9g/day which supplies about 15-16% of total calories. The results of this study do not agree with those reports of western societies which showed the positive correlation between calorie and fat intake and the incidence of breast and cervical cancer. Even through the calories and fat intake of the subjects were not high, it was higher than national average, especially in breast cancer patients. From this study, dietary factors does not seem to be a major risk factor in cancer incidence in Korea. However, the tendency of the increasing consumption of fat could be a contributing risk factor together with overweight.
BACKGROUND/OBJECTIVES: The prevalence of obesity, a worldwide pandemic, has been increasing steadily in Korea. Reports have shown that increased intermuscular adipose tissue (IMAT) is associated with an increased risk of cardiovascular disease, independent of body mass index. However, the relationship between dietary intake and IMAT accumulation in the Korean population remains undetermined. The objective of this study was to evaluate regional fat compartments using advanced magnetic resonance imaging (MRI) techniques. We also aimed to investigate the association between IMAT amounts and dietary intake, including carbohydrate intake, among Korean individuals with obesity. SUBJECTS/METHODS: This cross-sectional study, performed at a medical center in South Korea, recruited 35 individuals with obesity (15 men and 20 women) and classified them into 2 groups according to sex. Anthropometry was performed, and body fat distribution was measured using MRI. Blood parameters, including glucose and lipid profiles, were analyzed using commercial kits. Linear regression analysis was used to test whether the IMAT was associated with daily carbohydrate intake. RESULTS: Carbohydrate intake was positively associated with IMAT in all individuals, with adjustments for age, sex, height, and weight. No significant differences in blood indicators were found between the sexes. CONCLUSIONS: Regardless of sex and age, higher carbohydrate intake was strongly correlated with greater IMAT accumulation. This suggests the need to better understand sex differences and high carbohydrate diet patterns in relation to the association between obesity and metabolic risk, which may help reduce obesity prevalence.

We aimed to investigate associations of dietary diversity (DD) with gut microbial diversity and the development of hen's egg allergy (HEA) in infants. We enrolled 68 infants in a high-risk group and 32 infants in a control group based on a family history of allergic diseases. All infants were followed from birth until 12 months of age. We collected infant feeding data, and DD was defined using 3 measures: the World Health Organization definition of minimum DD, food group diversity, and food allergen diversity. Gut microbiome profiles and expression of cytokines were evaluated by bacterial 16S rRNA sequencing and real-time reverse transcriptase-polymerase chain reaction. High DD scores at 3 and 4 months were associated with a lower risk of developing HEA in the high-risk group, but not in the control group. In the high-risk group, high DD scores at 3, 4, and 5 months of age were associated with an increase in Chao1 index at 6 months. We found that the gene expression of IL-4, IL-5, IL-6, and IL-8 were higher among infants who had lower DD scores compared to those who had higher DD scores in high-risk infants. Additionally, high-risk infants with a higher FAD score at 5 months of age showed a reduced gene expression of IL-13. Increasing DD within 6 months of life may increase gut microbial diversity, and thus reduce the development of HEA in infants with a family history of allergic diseases.
Objectives : Abnormal regulation of glucose and impaired lipid metabolism that result from a defective or deficient insulin are the key etiological factor in type 2 diabetes mellitus. The our study investigated the effects of Gamioknyeo-jeon (GO) on blood glucose and lipid metabolism improved by it in db/db mice (a murine model of type 2 diabetes mellitus).Methods : The animals were divided into 3 groups: Normal groups were not-treated C57BL/6 mice; Control groups were treated orally with DW in db/db mice; GO groups were treated orally with GO (200 ㎎/㎏/day) in db/db mice. After mice were treated with GO for 5 weeks, we measured AST, ALT, creatinine, BUN, body weight, food intake, blood glucose, insulin and lipid levels (total cholesterol, HDL cholesterol, and LDL cholesterol and atherogenic index(AI) and cardiac risk factor(CRF).Results : Serum AST, ALT, creatinine, BUN levels were not changed by GO do not show any toxic effects. GO groups were decreased in body weight, food intake and blood glucose level among compared to Control groups. Also, GO groups were found to have atherogenic Index and cardiac risk factor as well as lipid metabolism improvement (total cholesterol and LDL cholesterol decrease). Finally, GO groups were increased the insulin compared to Normal and control groups.Conclusions : We suggest that GO may have the control effects of diabetes mellitus by improving blood glucose control and lipid metabolism.
The present study was designed to compare the nutrient intake and iron status of athletic female students majoring in aerobics (n=18) to those of age-matched(20-22 yr) sedentary controls (n=19). The athletic students were exercising regularly for 9.1$\pm$1.4 hrs/wk and the mean training period of aerobics was 2.9$\pm$0.2 years. Means of height, weight, and body mass index calculated as the Quetlet index were similar between athletic and sedentary students. However, mean body fat % of the athletic students (22.3$\pm$1.0%) was significantly lower than that of the sedentary controls (25.8$\pm$0.6%), indicating the effects of routine exercise. Mean daily iron intake was not significantly different between groups (9.9$\pm$0.7 mg vs. 10.9$\pm$0.8 mg), but much lower than the Korean RDA (18 mg/d) in both groups. Dietary calcium intake of the athletic students was significantly lower than that of the sedentary controls. Hematocrit (Hct) and hemoglobin (Hb) values were significantly lower in the athletic students than in the sedentary students (Hct : 40.0$\pm$0.7% vs. 43.8$\pm$0.5% ; Hb : 12.6$\pm$0.3g/dl vs. 14.8$\pm$0.3 g/dl). However, other iron status values such as serum iron, TIBC, and transferrin saturation were not significantly different between groups. Therefore, the low hemoglobin levels in the athletic group are probably due to plasma dilution in endurance-trained individuals. Serum ferritin level was a little lower in the athletic group, but no significant difference between groups was found. Serum triglyceride concentration in the athletic students was significantly lower than that in the control students. In conclusion the findings suggest that regular training of female athletes majoring in aerobics is associated with an increased risk of pseudoanemia due to plasma volume expansion and a decreased risk of coronary heart disease by decreasing body fat and blood lipid level.
