This study was performed to investigate the prevalence of metabolic syndrome (MS) and assess nutrient intake levels for the purpose of improving MS risk factors. The participants in this study were 512 adults consisting of 271 men and 241 women aged 30 and over, who visited a public health center for a medical check up. The diagnosis of MS subjects was adapted from the NCEP-ATPIII guidelines and the WHO Asia-Pacific Area criteria for obesity. The MS group was defined as subjects displaying three or more risk factors, and the non MS group was defined as those displaying two or less risk factors. A dietary survey was conducted using the 24-hour recall method. The number of subjects displaying MS syndrome factors was 158 (30.9%), broken down into, 89 men and 69 women. Regarding risk factors in the MS group, the prevalence of waist circumference was 40.5%, hypertension 34.2%, hyperglycemia 31.0%, low HDL-cholesterol 24.7%, and hypertriglycemia 19.6%. BMI, sistolic blood pressure, blood glocose, blood triglyceride, and blood HCL-cholesterol of the MS group were significantly higher compared to the non MS group. Male subjects in the MS group reported high intakes of cereals, sugar, fruits, meat and poultry, oil and fats, and beverages and total food intake was significantly higher compared to the non MS group. Women in the MS group reported high intakes of meat and poultry, milk and dairy products, beverages, and seasonings, and total food intake was higher compared to the non MS group. Dietary diversity score (DDS) was 3.82~4.04, which was not significant among the groups. In men, dietary variety score (DVS) was 16.3 in the MS group and 19.4 in the non MS group, whereas in women, the DVS was 15.2 in the non MS group and 17.0 in the MS group. In GMVDF pattern, 11111 pattern was 30.7%, followed by 01111 for men and 11101 for women. Calorie, fat, and cholesterol intakes in men as well as, calorie, fat, and folate intakes in women in the MS group were higher compared to the non MS group. Intakes of protein, P, Fe, Na, vitamin $B_1$, vitamin $B_2$, niacin, vitamin E, and Zn were higher than the KDRIs. On the other hand, intakes of Ca, K, fiber, vitamin $B_2$, and vitamin C were below the KDRIs. Intakes of lipids, animal food, Na, and cholesterol in the MS group were higher compared to the non MS group, whereas intake of dietary fiber was lower. Our results indicate that continuous, systematic nutritional education program must implemented to reduce the risk factors associated with MS.

The content of nutrients, proteins, and oils of crop seeds is affected by global climate change due to the increase in temperature. Information regarding the effects of increased temperature on soybean seed nutrition is limited despite its vital role in seed quality and food security. The objective of this study was to determine the effect of increasing temperature on seed nutrient, protein, and oil content in two soybean [Glycine max (L.) Merr] cultivars (Daewonkong and Pungsannamulkong during the reproductive period in a temperature-gradient chamber. Four temperature treatments, Ta (near ambient temperature), $Ta+1^{\circ}C$ (ambient temperature+$1^{\circ}C$), $Ta+2^{\circ}C$ (ambient temperature+$2^{\circ}C$), $Ta+3^{\circ}C$ (ambient temperature+$3^{\circ}C$), and $Ta+4^{\circ}C$ (ambient temperature+$4^{\circ}C$), were established by dividing the rows along the temperature gradient. At maturity, increased temperature did not significantly affect the concentration of P, K, Ca, and Mg. The protein and oil content was significantly correlated with temperature. At maturity, the protein content of DWK and PSNK was reduced at $Ta+4^{\circ}C$. The oil content was the highest at $Ta+4^{\circ}C$ in DWK, whereas it decreased in PSNK at $Ta+4^{\circ}C$. Consequently, the biochemical composition of soybean seeds changed with the increase in temperature. These results illustrate the effects of temperature on soybean seed nutrient, protein, and oil content, which can help improve soybean quality at different temperatures. Thus, the biochemical composition of crop seeds can be changed in accordance with nutritional requirements for the benefit of human health in the future.
