We investigated weight loss effect of personalized diet education in overweight/obese Korean adults. Overweight/obese Korean adults (body mass index [BMI] ≥ 23 kg/m2 or waist circumference [WC] ≥ 90 cm for men, ≥ 85 cm for women) were recruited, and 40 participants who completed the 10-week intervention were finally included in the analyses. At first visit, study participants (small group with individual counseling) were educated for optimal diet by clinical dietitian, and checked for their compliance through telephone/text message every 1–2 week during the intervention. Anthropometric and biochemical parameters and dietary intake were investigated. Body weight, BMI, WC, and body fat mass were significantly reduced in whole participants. Hemoglobin A1c, insulin, and low-density lipoprotein cholesterol were also significantly decreased after the intervention. Total energy intake (EI) during the intervention was not significantly decreased compared to the baseline value, but the proportions of energy derived from macronutrients were within the ranges recommended by 2015 Dietary Reference Intake for Koreans. Based on actual EI, participants were classified into high-adherence (HA) (prescribed EI ± 25%, n = 29), low-adherence I (LA-I) (< 75% of prescribed EI, n = 7), and low-adherence II (LA-II) group (> 125% of prescribed EI, n = 4). Only HA group showed significant improvements in anthropometric parameters, glycemic control and lipid profile. Interestingly, LA-I group showed significant increases in glucose, insulin, C-peptide and insulin resistance. In conclusion, a shift from overweight/obesity to healthy weight can be accomplished by high adherence to personalized diet modification, not by EI reduction.

PURPOSE: The consumption of processed foods has recently been increasing due to changes in the living environment. The purpose of this study was to identify the contribution of processed food to the nutrient intake of adult Koreans. METHODS: A total of 15,760 adult people in the 6(th) National Health and Nutrition Examination Survey (2013 ~ 2015) were included in this study. According to the Korea Food and Drug Administration's classification criteria for processed foods, the 24 hour dietary recall data of the subjects were classified as processed food or natural food. The processed food intake, nutrient intake and major processed food sources by food groups were analyzed. RESULTS: Men consumed more processed foods than did the women. Consumption of processed foods decreased with age, but it increased with the education level and the income level. The total daily processed food intake accounted for 68.1% of the total food intake. The food groups with high processed food intake were beverage, vegetables, cereals and grain products, fruits, and milk and dairy products in this order. The top food source of each food groups were beer, kimchi, bread, processed apple products, and milk. After adjusting for age, gender, and energy intake, all the nutrient intakes and percentage of dietary reference intakes for Koreans, except carbohydrates, were significantly higher in processed foods than in natural foods. The sodium intake from the processed food was 96.3% of total daily sodium intake. The intakes of nutrients from processed foods, excluding vitamins C, dietary fiber, iron, and vitamin A, were higher in men than in women. The intake of sodium from processed foods was highest for people of 30 ~ 49 years of age, and the intake of sodium from processed foods decreased for people over 50. CONCLUSION: Korean adults consumed more processed food than the natural food, consuming more calories and most of the nutrients from the processed food overall total daily intakes. The intake of processed foods is expected to further increase in the future, and nutritional education and research on the ingestion and selection of healthy processed foods are necessary.

BACKGROUND: A premeal load of protein can increase satiety and reduce energy intake. Dietary fiber also conveys metabolic benefits by modulating energy intake. We made a protein-enriched, dietary fiber-fortified bar (PFB) and aimed to investigate its effects on food intake and gut hormone secretion in healthy individuals.METHODS: Twenty subjects with normal glucose tolerance were enrolled. On three separate visits, the subjects received, in a randomized order, one of the following: a PFB containing 73 kcal with 10.7 g of protein and 12.7 g of dietary fiber; a usual bar (UB) containing the same calories as the PFB but only 0.9 g of protein and no dietary fiber; or water (control). After 15 minutes, the subjects had ad libitum intake of a test meal. Food consumption, appetite, and plasma gut hormone levels were measured.RESULTS: Total energy intake, including the bar and the test meal, was significantly reduced with the PFB preload compared to the water (904.4±534.9 kcal vs. 1,075.0±508.0 kcal, P=0.016). With the UB preload, only the intake of the test meal was reduced (P=0.044) but not the total energy intake (P=0.471) than the water. Fullness was also significantly increased after the PFB. In addition, postprandial glucose levels decreased and glucagon-like peptide-1 levels increased with the PFB compared with both the UB and water.CONCLUSION: In healthy individuals, a premeal supplementation of PFB reduced total energy intake and decreased postprandial glucose excursion. This finding necessitates long-term studies regarding clinical use in obesity.

BACKGROUND/OBJECTIVES: Available data suggest that seasonal changes may influence the nutritional status and overall health of elderly individuals. Therefore, this study was conducted to investigate the effects of seasonal changes and related factors on energy and nutrient intake of older adults. SUBJECTS/METHODS: Individuals aged 65 years or over were prospectively enrolled in this single-center study (male: 11, female: 20). Data were collected between May 2013 and February 2014 during winter, spring, summer and autumn. Food consumption and biochemical parameters were taken during each season to assess the seasonal nutrition status of the elderly. Upon analysis of biochemical parameters (retinol, vitamin D and vitamin C), an high-performance liquid chromatography device was utilized whereas an Immulite 2000 device was utilized during analysis of serum folic acid and parathyroid hormone. RESULTS: Fruit, fat, egg and bread consumption varied seasonally in males and females (P < 0.05). During winter, daily energy intake was found to be greater than in other seasons in males (557 kcal) and females (330 kcal) (P < 0.05). Additionally, carbohydrates, vegetable protein, n-3 fatty acid and sodium intake increased in winter, while the n-6/n-3 ratio increased in summer among males (P < 0.05). Dietary fiber and sodium intake in winter, vitamin C, iron and zinc intake in spring, and cholesterol, retinol, vitamin D and niacin intake in autumn were found to be higher in females when compared to other seasons (P < 0.05). Serum parathyroid hormone level was higher in winter, and vitamin D level was higher in autumn in both genders (P < 0.05). In males, blood folic acid level was higher in winter, while vitamin C level was higher in females, and there was no seasonal variation in retinol concentration (P < 0.05). CONCLUSION: Food consumption and biochemical parameters showed significant seasonal variations in older adults. It is not clear if nutrition plans in older adults will benefit from consideration of seasonal changes in eating habits.

PURPOSE: The purpose of this study was to evaluate the dietary potassium intake, Na/K intake molar ratio, consumption of 18 food groups, and foods contributing to potassium intake of Korean adults as well as the relationships among quartile of potassium intake level and blood pressure, blood biochemical index. METHODS: This study was conducted using the Korea National Health and Nutrition Examination Survey, 2007~2010. The total number of subjects was 20,291. All analyses were conducted using a survey weighting to account for the complex survey design. RESULTS: Overall average intakes of potassium were 2,934.7, 3,070.6, 3,078.1, and 3,232.0 mg/day, and they significantly increased by year in Korean adults. The average dietary potassium intake was close to adequate intake (AI), whereas that of women was considerably lower than the AI. The Na/K intake molar ratio in males (2.89~3.23) was higher than in females (2.62~2.95). The major food groups contributing to potassium intake were vegetables, cereals, and fruits/meats. The two major foods contributing to potassium intake were polished rice and cabbage kimchi. The rankings of food source were as follows; polished rice > cabbage kimchi > potato > oriental melon > sweet potato > seaweed > radish > apple > black soybean. In 50~64 year old females, systolic blood pressure (SBP) significantly decreased (p < 0.01) and HDL-cholesterol significantly increased (p < 0.05) as potassium intake increased. Triglyceride (TG) was significantly higher in the other quartile of potassium intake level than in the first quartile (p < 0.05). CONCLUSION: In conclusion, our study suggests the need for an appropriate set of dietary reference intakes according to caloric intake by sex and age groups and for development of eating patterns to increase potassium intake and decrease sodium intake.

BACKGROUND: This study aims to evaluate the importance of snacks to a balanced diet by assessing snack consumption patterns and factors associated with eating snacks of Korean elders of 60 years or more. METHODS: This analysis is based on participants from the 2013-2014 Korea National Health and Nutrition Examination Survey. Meal or snack consumption was based on a 24 hours recall data, and the adequacy of each nutrient intake was based on the Dietary Reference Intakes by the Korea Nutrition Society. The cutoff for snack consumption valued as meaningful was more than 200 kcal/day of snack energy intake. RESULTS: Korean male elders of age 60 years or more are consuming 333.6±11.1 kcal of snack and 271.7±7.4 kcal for females. When consumed together with meals, snack consumption increased the adequacy of all nutrients intake, except sodium. Based on energy contribution, male Korean elders are consuming snack food group in order of beverage and alcohols, grains, and fruits, while for females the order was grains, fruits, and dairy. Older age (men and women), joblessness (men), and chronic disease (women) were positively associated with having snack of 200 kcal or more per day, whereas ‘living with a partner (men)’, alcohol intake frequency of more than twice per week (men), and ‘doing regular aerobic physical activity (women)’ showed negative association. CONCLUSIONS: Snack consumption of Korean elders contributed to more adequate nutritional status, but improvement of food groups is needed because they were mainly concentrated on grains.

Numerous studies have investigated quantifying dietary intake according to the weight status of children and adolescents. However, studies on differences in quality among diets remain scarce. This study compared diet quality by weight status and examined correlations between quality of diet and obesity in children and adolescents. Two hundred fourteen children and adolescents aged between 9 and 18 years participated in this study (Normal weight n=104, Obesity n=110). The data related to food intake were investigated by dietary records, Diet Quality Index-International (DQI-I), and Nutrition Quotient (NQ) and then compared with Dietary Reference Intakes for Korean (KDRIs). In DQI-I, moderation factor (control of unhealthy foods) score was 21.7 in the normal weight group and 19.5 in the obesity group. The normal weight group showed a higher score for moderation factor than the obesity group (P<0.001). Compared with KDRIs, vitamin B6, folate, vitamin C, vitamin E, calcium, potassium, and zinc intakes were insufficient in both groups. Multiple logistic regression analysis revealed that DQI-I moderation was negatively associated with obesity (OR=0.77, 95% CI 0.69-0.87) after adjustment for age, gender, income, and total energy intake. Our results suggest that children and adolescents require nutritional education to understand the importance of vitamin and mineral consumption. Especially, education for children and adolescents with obesity needs to emphasize moderation of nutrient intake that can cause diseases with hyper-ingestion such as sodium and high calorie-low nutrition foods.

Malnutrition, HIV and tuberculosis (TB) disease is a triangle of death that should be given attention. This study was comparing nutritional status of HIV patients with and without TB in Semarang, Indonesia, to describe the effect of TB burden to their nutritional status. The study design was cross-sectional study. The study began with an examination of sputum and chest X-rays, then examined by anti- HIV antibodies using the method of screening of 3 times. About 56 subjects were recruited to the HIV group and 36 subjects to the HIV-TB. The anthropometric examination was carried out by using scales, microtoise, Mid Upper Arm Circumference ribbon, and Body Impedance Analyzer to measure body fat. Interviews were conducted to the subject on physical activity examination, 24 hours dietary recall and food frequency questionnaire. Data analysis using Independent t-test or Mann-Whitney test. The results showed that group of HIV- TB had worse nutritional status than those suffer from TB. Body weight, BMI, MUAC, BMR, and Vitamin A blood serum in HIV patients with TB was significantly lower than the HIV group. The nutritional status of HIV patients with TB was significantly more malnourished than counterparts (underweight: 25.7% vs 14.3%). Dietary intake of vitamin A, Fe, Zn, energy, protein and fat was better in HIV group compared to HIV-TB group. Respondents who are 19 years old on average were stunting, an indicator of malnourished in a long time. TB can worsen the nutritional status of HIV patients if not supported by good nutrition.

A balanced dietary intake plays an important role in the prognosis of breast cancer and is one of the modifiable factors in preventing cancer recurrence. This study aims to determine the dietary intake among breast cancer survivors in East Coast of Peninsular Malaysia. A total of 125 breast cancer survivors, aged 37 to 72 years, with mean duration of survivorship of 6.1 ± 3.9 years were recruited from two main referral hospitals in Terengganu and Kelantan. Majority ofthe respondents were Malay (94.4%) with a mean BMI of 27.7 ± 5.07 kg/m², and were diagnosed with stage II cancer (66.0%). Dietary intake was estimated using a semi-quantitative food frequency questionnaire (FFQ). The results show that the mean daily intake of energy was 1764 ± 378 kcal/day, protein was 72.38 ± 33.6 g/day (16.5% of energy), carbohydrate was 243.0 ± 62.2 g/day (55% of energy) and fat was 55.8 ± 15.6 g/day (28% of energy). Overall, breast cancer survivors in this study had an adequate daily intake of vitamins and minerals according to Malaysian Recommended Nutrient Intakes (RNI) except for dietary fibre (10.6 ± 4.2 g/day), monounsaturated fatty acids (20.7 ± 5.7 g/day), polyunsaturated fatty acids (8.0 ± 2.2 g/day), calcium (561.0 ± 257.1 mg/day), iron (18.3 ± 7.2 mg/day) and potassium (1813.4 ± 531.1 mg/day) which was lower than the recommendation. Meanwhile, intake of sodium (2592 ± 1697 mg/day), protein (80.4 ± 33.6 g/day), saturated fatty acids (26.9 ± 14.2 g/day), vitamin B2 (1.9 ± 1.1 mg/day) and vitamin C (151.1 ± 149.3 mg/day) exceeded the recommendation by 135.0%, 139.0%, 166.9%, 154.6% and 152.0%, respectively. There was no significant difference in dietary intake between cancer survivors who were diagnosed in the past five years and those who were diagnosed more than five years ago (p>0.05) except for fat (p<0.001), saturated fatty acid (p=0.006), monounsaturated fatty acid (p=0.005) and polyunsaturated fatty acid (p=0.003). As a conclusion, breast cancer survivors in East Coast of Peninsular Malaysia had an adequate intake of most nutrients except for dietary fibre, monounsaturated fatty acids, polyunsaturated fatty acids, calcium, iron and potassium which was below the recommendation and sodium, protein, saturated fatty acids, vitamin B2, vitamin C which was above the recommendation. The intakes between long-term and short-term survivors were also comparable showing sustained dietary intake throughout survivorship.

Dietary intake is a major contributor to both the development and management of type 2 diabetes. Multiple studies have provided evidence that diabetes nutrition therapy is effective for improving glycemic control and other metabolic outcomes. However, there remains no conclusive evidence as to which diet, if any, is the most effective for optimizing glycemic control in patients with diabetes. The roles of differing macronutrient percentages, eating patterns and weight loss interventions are controversial topics concerning dietary intake. In particular, there are no ideal percentages of macronutrients or eating patterns that can simultaneously apply to all persons with diabetes. A reduced energy intake for persons with type 2 diabetes, referred to as nutrition therapy intervention, has been shown to be effective for achieving glycemic and other metabolic outcomes. For such a treatment option to be effective, diabetes nutrition therapy must be individualized. Thus, treatment goals, personal preference, individual ability and willingness to make lifestyle changes must all be considered when educating or counseling individuals with diabetes.
