Plasma carotenoid levels were compared among 64 healthy male subjects (control) and 38 patients of ischemic heart disease(IHD) and 20 ones of cerebral infarction(CI) all of whom were over 50years of age. Another 98 healthy male subjects aged 23 to 58 were selected to compare their plasma carotenoid levels by age groups, Levels of lutein ,zeaxanthin and crpytoxanthin were lower in IHD(34$\pm$2, 13$\pm$1 and 62$\pm$7$\mu g$/dl)and CI(36$\pm$3, 12$\pm$2 and 41$\pm$6$\mu g$/dl)patient groups than in control group (84$\pm$5, 16$\pm$2 and 69$\pm$3$\mu\textrm{g}$/dl) while those of lycopene, $\alpha$-and $\beta$-carotene varied little among the three groups. The sum of the six carotenoid levels were levels were, therefore,highest(205$\pm$14$\mu\textrm{g}$/dl) in the control group followed by IHD(155$\pm$15$\mu g$/dl) and CI(128$\pm$17$\mu g$/dl) patient groups, Among the 98 healthy male subject for the age group study, levels of the three major carotenoids increased with age from the twenties to the fifities ; lutein, from 64$\pm$6 to 89$\pm$8$\mu g$/dl, cryptoxanthin, 57$\pm$8 to 73$\pm$4$\mu\textrm{g}$/dl and $\beta$-carotene were more significantly correlated(r=0.30 to 0.61, p<0.01), whereas levels of lycopene and $\alpha$-caroteme were significantly(r=0.21 - 0.23, p<0.05) correlated.

This study examined the determinants of healthy food purchases before and after COVID-19 in Korea. Binomial and multinomial logistic regression models were applied to Korea Rural Economic Institute's Food Consumer Behavior Survey data from 2019 to 2021. The analysis revealed a significant decrease in the non-intake of healthy food in 2021 compared to 2019, suggesting the impact of COVID-19 on healthy food consumption. Consumption patterns also changed, with a decrease in direct purchases and an increase in gift-based purchases. Several variables showed significant effects on healthy food intake. Single-person households exhibited a higher probability of eating healthy food after COVID-19. The group perceiving themselves as healthy had a lower likelihood of consuming healthy food pre-COVID-19, but this changed after the pandemic. Online food purchases, eco-friendly food purchases, and nut consumption showed a gradual decrease in the probability of non-intake over time. Gender and age also influenced healthy food intake. The probability of eating healthy food increased in the older age group compared to the younger group, and the probability increased significantly after COVID-19. The probability of buying gifts was significantly higher in those in their 60s, indicating that the path to obtaining healthy food differed by age.

A survey of how dietary patterns and living habits were related to individual health status was undertaken amongst the elderly in Jeon-ju the results were analyzed in order to collect information which would be useful in preventing chronic diseases and promoting health in the general population. Two hundred and thirty elderly people, 73 min (31.7%) and 157 women (68.3%) from the colleges and households in the Jeon-ju area, were studied in truly and August, 1999. Average scores for men and women, respectively, in nutrition-related questions were as follows: 4.98 $\pm$ 0.24 and 5.24 $\pm$ 0.13 in a nutrition knowledge test (maximum score= 10), 25.92 $\pm$ 0.39 and 26.04 $\pm$ 0.26 for nutrition attitudes (maximum=50), and 11.25 $\pm$ 0.15 and 10.70 $\pm$ 0.12 for dietary habits (maximum= 15). The percentages of smokers and drinkers in the sample were 23.3% and 31.5% among men, and 3.2% and 10.8% among women, respectively, while those who took regular exercise were 67.1% among men and 34.8% among women. Average scores of clinical symptoms for men and women were 27.62 $\pm$ 0.62 and 33.36 $\pm$ 0.47, respectively. Analysis was carried out on the effects of individual dietary patterns and lifestyles on current health status in a healthy group (below the 25 percentile in clinical symptom scores) and an unhealthy group (above the 75 percentile in clinical symptom scores). The results show that the healthy elderly group had relatively good nutrition knowledge, nutrition attitudes, and dietary patterns, ate with family, took nutrition supplements and snacks, and did not smoke. The most healthy group ate out once a month, drank small quantities of alcohol occasionally, and exercised once or twice a week. We believe that the results of this study will be helpful in developing or coordinating plans or programs f)r improving the health of elderly people.

The concern of the antioxidant micronutrient status in normal healthy people, including antioxidant trace minerals such as Cu, Zn, Mn, Fe and Se is focused since systemic oxidation is involved in various chronic diseases. In the present study, we evaluated the concentration of trace minerals (Cu, Zn, Mn, and Fe) which are considered as potential antioxidant minerals in plasma, red blood cells (RBCs) and urine in normal healthy Korean subjects. The 760 subjects (male 341, female 419; mean age 54.2 $\pm$ 18.9) were recruited from the rural, urban and metropolitan city in South Korea. Dietary intake was evaluated using 24-hours recall for general major nutrient intake assessment. The trace elements (Cu, Zn, Mn, and Fe) concentrations in plasma, RBCs, and urine were measured by inductively coupled plasma spectrophotometer (ICP) and atomic absorption spectrophotometer (AAS). Cu and Zn levels in plasma, RBCs and urine in normal healthy South Koreans were within the normal range of those mineral levels, but Mn and Fe levels were higher compared to the normal range of those mineral levels. None of the selected trace mineral levels in plasma and RBC's was lower than the normal range value. The results showed that Zn and Cu levels in plasma and RBC's in Korean were within the normal range, and plasma and urinary Mn and Fe levels were higher than the normal reference values. Potential antioxidant trace mineral (Cu, Mn, Zn and Fe) levels in Koreans are within or a bit higher than the normal range.

This study was conducted to examine the differences in perceived body weight and image and various lifestyles based on the self-rated health of university students when gender was adjusted. Five hundred fifty-five participants were asked their perceived health condition, and 58, 289, 160 and 48 students answered themselves as "very healthy", "healthy", "normal", and "unhealthy", respectively. As compared to the other 3 groups, "unhealthy" group showed higher proportions in dissatisfaction of body weight and negative perception of body image (P < 0.01). As health related lifestyles, "very healthy" group reported longer sleeping time than "unhealthy" group (P < 0.05), and had a higher proportion of people with regular exercise. Among the dietary behaviors, the frequencies of followings significantly different among the groups: "Regularity of meal time" (P < 0.01), "Eat protein foods more than twice a day" (P < 0.001), "Eat vegetables" (P < 0.01), "Eat fruit and fruit juice" (P < 0.01), "Eat vegetable oil added foods" (P < 0.01), "Eat seaweed" (P < 0.01), "Eat breakfast" (P < 0.01), "Modulation in animal fat and high in cholesterol intake" (P < 0.01). Particularly, higher proportion of subjects answered "very healthy" had higher frequencies (6-7 times/week) of these dietary behaviors. Overall results suggest that healthy lifestyle including adequate sleeping time, regular exercise, and good dietary behaviors might be potential factors affecting positive perception of health. In addition, positive perception of body weight and image were related with positive perception of health.

Recent studies have evaluated the association between specific beverage intake and metabolic risks in adults. However, more evidence is needed to examine the association between the Healthy Beverage Index (HBI) and metabolic factors. Therefore, this study investigated the relationship between HBI and metabolic factors in adults. In this cross-sectional study, 338 overweight and obese individuals living in Tabriz, Iran were selected. Data on beverage consumption, demographics, physical activity, and anthropometric characteristics were evaluated using validated standard protocols. The predefined HBI was calculated based on previous studies. The mean value of HBI index among all of the participants was 59.76 ± 6.51. Those at the higher HBI scores had significantly lower waist circumference, waist-to-hip ratio, fat mass, and weight (p < 0.05). HBI and triglyceride scores also had a significant relationship. It has been shown that at higher HBI scores compared to lower scores, high-density lipoprotein cholesterol levels increase while homeostatic model assessment for insulin resistance, low-density lipoprotein cholesterol, total cholesterol, and blood pressure decrease. HBI scores higher among Iranian adults were associated with a better chance of losing weight and weight loss and a better lipid profile, and lower blood pressure. Therefore, HBI can be a useful and helpful tool for assessing the overall quality of beverages adults consume. However, further studies are warranted to confirm the possible health effects of healthy beverage index.
