Diet quality index DQI) offers a new way of comparing eating habits across populations and across countries. Nutrients and food consumption data from 100 elderly Korean women aged 65 and older were collected in Seoul or Kyunggi-do, Korea by the 24 hour recall method. Diet quality index (DQI) was computed for 1049 elderly women (65 and older) from the 1994-1996 Continuing Survey of Food Intakes by Individuals (CSFII) in the US according to US dietary guidelines, and applied to the diet of elderly Korean women for purposes of comparison. A modified 16-point DQI awarded 2 points each for moderate consumption of fat ($\leq$ 30% energy), saturated fat ($\leq$ 10%), cholesterol ($\leq$ 300 mg/day), sodium ($\leq$ 2400 mg/day), and protein ($\leq$ 100% RDA), adequate intakes of carbohydrate ($\qeq$50% energy) and calcium ($\qeq$ 100% RDA), and plenty of fruits and vegetables ($\qeq$ 5 servings). Criteria were based on US dietary guidelines. Partial scores were given if subjects were close to meeting these cutoff points. Diets with $\leq$ 300 mg cholesterol/day were reported by 97% or the Korean sample and 82% of the American sample, while 90% of the Koreans and 42% of the Americans met the goal of $\leq$ 30% of energy from fat, and 98% of the Koreans and 47% of American met the recommendation of $\leq$ 10% of energy from saturated fat. In contrast, only 8% of the Korean sample met the sodium recommendation of $\leq$ 2400 mg sodium per day, whereas 54% of the American subjects met this goal. The mean DQI scores were 10.1 for the elderly American women and 11.3 for the elderly Korean women. Overall, the elderly Korean diet was more consistent with the US dietary guidelines than the elderly American diet.

This study evaluates nutrition knowledge, dietary behaviors and food group acceptability based on a sample of 514 of new employees in Gyeonggi area. Among the respondents, 70.6% of male, and their age was 30.7 Most were college graduates (94.9%) and unmarried (86.3%). Based on the BMI males tended to be overweight, whereas females, normal. In terms of health consciousness based on five-point Likert-type scale, the average score for the health status was 4.18 indicating good health, and health attention was 4.88 indicating high health attention. Dietary behaviors were evaluated using five-point Likert-type scale. According to the results, the total score for regular diet based on 5 items was 9.6; that for a balanced diet based on 7 items was 22.2; and that for practical diet action based on 8 items was 22.3. That is, the respondents were on an irregular diet but tried to balanced diet through appropriate diet action. Food acceptability was evaluated using a five-point Likert scale ranging from "strongly dislike(1)" to "strongly like(5)". The score of meat group was 3.67; that for the fish 3.43; and that for the vegetable group was 2.86. Females were slightly more like to accept fruits 3.60 than males 3.48;(p<0.05). The total score for nutrition knowledge based on 35 items was 20.5. A balanced diet was correlated with egg acceptability (p<0.01); energy-related knowledge with confectionery preferences (p<0.05); and vitamin knowledge, with snack affinity (p<0.05). Health attention was negatively correlated with seafood preferences for male(p<0.05) and with snacks for females(p<0.05). The respondents were strongly interested in and aware of their health, but this did not lead to their food preferences. These results suggests that dietary habits can lead to nutritional balance for maintaining the health of employees.

The purpose of this study was to investigate the effects of nutrition counseling on diabetes management by determining changes in anthropometry and blood components as well as knowledge and practice of diet therapy and nutrient intake in 34 (male 11, female 23) type 2 diabetes patients. The knowledge and the practice of diet therapy, drinking, smoking and exercise were analyzed by questionnaires. Dietary nutrient intake were obtained from the patients by the 1 day 24-hr recall. Blood glucose level and blood pressure were measured before and 3 months after the treatment. The results are summarized as follows: Average weight (p<0.05) and body mass index (p<0.05) were significantly lower post-counseling. Fasting blood glucose levels (p<0.01) and postprandial-2hour blood glucose levels (p<0.01) were also significantly lower post-counseling. In lifestyle changes for self-management the patients showed significantly higher exercise habits post-counseling (p<0.01). Regarding their level of diet knowledge, they showed significantly higher levels post-counseling in six items such as importance of diet therapy for diabetes (p<0.001), principles of diet therapy (p<0.001), nutrient composition of foods (p<0.01), carbohydrate composition of foods (p<0.001), the prescribed calories (p<0.001) understanding food item and exchange units of cereals, grains (p<0.001) and fruits, juices (p<0.001). Regarding their diet practices, the patients showed significantly higher levels of practice post-counseling in keeping within permitted meal size (p<0.001), using food exchange lists (p<0.001), keeping exact meal times (p<0.01), and controling sweet foods (p<0.001). Protein (p<0.05), animal lipid (p<0.05), and vitamin C (p<0.05) intakes were significantly higher post-counseling.

BACKGROUND/OBJECTIVES: Cardiovascular diseases (CVDs) are the leading cause of death in Koreans, and eating habits, including diet quality, are among the etiologies of these diseases. Recently, various studies on regional health disparities have been conducted. However, there are limited studies on their relationship with nutritional factors. This study aimed to identify the magnitude of regional disparities in diet quality and prevalence of CVD in Korean adults. SUBJECTS/METHODS: This study included 17,646 participants aged ≥ 20 years from the 7^th (2013-2016) Korean National Health and Nutrition Examination Survey. Participants were classified into four groups based on their residential areas: City 1, City 2, City 3, and non-city. Demographic characteristics, health-related factors, body mass index (BMI), metabolic syndrome index, diet quality, and CVD prevalence were evaluated. RESULTS: In terms of demographic characteristics, age (P < 0.001), marital status (P < 0.001), educational level (P < 0.001), and income (P < 0.001) were lower in the non-city category. Health-related factors such as monthly drinking rate (P < 0.01) and mental stress (P < 0.05) were the highest in City 1 and lowest in the non-city group. Conversely, the current smoking rate (P < 0.05), BMI (P < 0.05), and prevalence of metabolic syndrome (P < 0.001) were the highest in the non-city group (P < 0.05). The non-city group also had the highest prevalence of CVDs (35.6%). This group had the lowest diet quality index (68.36 ± 0.22, P < 0.01), caused by low intake of fruit and calcium, a lack of sodium moderation, and an overall imbalance in the macronutrient and fatty acid ratio. When the diet quality index was increased by 1, the odds ratio for the prevalence of CVDs was reduced by 0.991 (P < 0.001), but this was not the case in all regions. CONCLUSIONS: This study provides useful information and data in identifying and resolving the regional health disparities related to CVD prevalence and implementation of public health nutrition systems.

Objectives: An association between dietary patterns and mental health in children has been suggested in a series of studies, yet detailed analyses of dietary patterns and their effects on ADHD (attention deficit hyperactivity disorder) are limited. Methods: We included 4569 children who had dietary intake data as part of the CHEER (Children's Health and Environmental Research) study conducted nationwide from 2005 to 2010. We assessed ADHD (Attention Deficit Hyperactivity Disorder) by the DuPaul's ADHD Rating Scales and dietary intake by a semi-quantitative food frequency questionnaire. Using intake data, we constructed five dietary patterns: "Plant foods & fish," "Sweets," "Meat & fish," "Fruits & dairy products," and "Wheat based." Results: The overall proportion of ADHD was 12.3%. Boys (17.8%) showed a higher rate of ADHD than girls (6.5%). The total intake of calories (85 kcal) and plant fat (2g) in the ADHD group was significantly higher than that of the normal group. ADHD was significantly negatively associated with dietary habits such as having breakfast and meal frequency, and positively associated with eating speed, unbalanced diet, overeating, and rice consumption. Regarding dietary patterns, the "Sweets" category was relevant to high ADHD risk (OR 1.59, 95% CI: 1.18, 2.15 for Q5 vs. Q1) in a linear relationship. An inverse, non-linear association was found between "Fruits & dairy products" and ADHD (OR 0.55, 95% CI: 0.39, 0.76 for Q4 vs. Q1). Conclusions: Our study confirms both positive and negative associations between diet and ADHD in elementary school age children. Moreover, linear or nonlinear associations between diet and ADHD draw attention to the possible threshold role of nutrients. Further studies may consider characteristics of diet in more detail to develop better intervention or management in terms of diet and health.

Background: The abrupt rise of colorectal cancer in developing countries is raising concern in healthcare settings. Studies on assessing relationships with modifiable and non-modifiable risk factors in the Pakistani population have been limited. The present investigation was designed to examine associations of dietary practices, addictive behavior and bowel habits in developing colorectal cancer (CRC) among patients in a low-resource setup. Materials and Methods: An age-gender matched case control study was conducted from October 2011 to July 2015 in Karachi, Pakistan. Cases were from the surgical oncology department of a public sector tertiary care hospital, while their two pair-matched controls were recruited from the general population. A structured questionnaire was used which included questions related to demographic characteristics, family history, dietary patterns, addictive behavior and bowel habits. Results: A family history of cancer was associated with a 2.2 fold higher chance of developing CRC. Weight loss reduced the likelihood 7.6 times. Refraining from a high fat diet and consuming more vegetables showed protective effects for CRC. The risk of CRC was more than twice among smokers and those who consumed Asian specific addictive products as compared to those who avoid using these addictions (ORsmoking: 2.12, 95% CI: 1.08 - 4.17, ORpan: 2.92, 95% CI: 1.6 - 5.33, ORgutka: 2.13, 95% CI: 1.14 - 3.97). Use of NSAID attenuated risk of CRC up to 86% (OR: 0.14, 95% CI: 0.07 - 0.31). Conclusions: Most of the findings showed concordance with the literature elucidating protective effects of consuming vegetables and low fat diet while documenting adverse associations with family history, weight loss, constipation and hematochezia. Moreover, this study highlighted Asian specific indigenous addictive products as important factors. Further studies are needed to validate the findings produced by this research.

The objective of this research was to examine the relationship between food preferences and personality of university students. The questionnaires were distributed to 198 university students in 2009. The data showed high correlation between personality and food preferences. According to the result of food preferences exams the most favorite food of university students was coffee, refreshing drinks, eggs, ice creams, bananas, porks, apples, chickens, weeds, grapes and food they dislike were sea cucumbers, livers, mung bean sprout, crown daisy, flat fishes, bean curd, green lavers, lotus roots, turban shells, egg plant etc. The correlation coefficient between food preferences and personality showed that male students had more dominance and sociability, and female students had more sociability and validity. On the other hand, a good diet group had higher responsibility and a poor diet group had higher sociability. Consequently, good food habits is essentially needed for the formation of desirable personality of students.

Careful scruting of the data indicate that malnutrition actually limits fertility. Spermatogenesis may likewise be impaired by inadequate diet, particularly one that is very poor in protein. For those who are underweight, increased caloric intake stressing high protein content is recommended. Included are supplementary vitamins, particularly B complex, which stimulate the appetite. Injudicious dieting by the woman to conform to current standards of beauty may also result in malnutrition. This contributes to faulty oogenesis and, in extreme dieting, may produce a long-standing amenorrhea. Obsity may also reduce fertility. Since most cases of obesity are due to over-eating, the full cooperation of the patient must be enlisted. And no device is effective for breaking up fatty deposits. Instead, a program of exercise is recommended. The treatment of both malnutrition and obesity is directed toward general dietary habits either weight gain or weight reduction, with a well balanced high protein diet.

The major food grains in Korea are rice and barley. The wheat was supplied from USA after World War II in 1945 and it changed the eating habits for Korean diet. The role of barley as a food grain has been diminished and that of wheat has been acknowledged; the consumption per capita per year of wheat is over the half of that of rice which is the staple grain in Korea. This article is a brief review on the background of wheat becoming the important grain in Korean diet and the following developmental story of flour mills. Emphasis was given to the statistics on flour mills industry.
