The purpose of this study was to investigate and examine the relationship between dietary habits, food intake patterns, and depression in Korean women with polycystic ovary syndrome (PCOS). The Center for Epidemiologic Studies Depression Scale Korean Version was used to determine whether a participant was depressed or not. The dietary habits were assessed by the Min-Dietary Assessment (MDA) method, and food intake data were collected by the 24-hour recall method on two non-consecutive days, at least 7 days apart, and the average of the two days was used to estimate the usual dietary intake. The total MDA scores of the Depression Group was significantly lower than that of the No-Depression Group ($31.5{\pm}6.4$ vs $33.4{\pm}6.0$, p = 0.027). The intake of cereals/potatoes/sugar products, milk and milk products, plant protein, and calcium for the Depression Group were significantly lower compared to the No-Depression Group. The Depression Group had a significantly higher percentage of energy intakes from protein as well as the consumption of fish and shellfish compared to the No-Depression Group. There was a significant inverse relationship between milk and milk products consumption and the prevalence of depression [OR (95% CI) for the highest tertile compared to the lowest: 0.390 (0.177-0.857); p for trend = 0.016]. There were also significant positive relationships between the prevalence of depression and the consumption of the following: fish and shellfish [OR (95% CI) for the highest tertile compared to the lowest: 2.319 (1.128-4.770); p for trend = 0.009], animal protein (p for trend = 0.049), and the percentage of energy intakes from protein [OR (95% CI) for the highest tertile compared with the lowest: 2.546(1.156-5.609); p for trend = 0.025]. Further studies are needed in order to investigate whether the intake of protein and of animal protein is indeed associated with depression in PCOS patients in Korea and the possible mechanisms thereof. The results of our study can be applicable for the development of effective nutrition counseling and education programs regarding PCOS patients with depression as part of their successful treatment regimen.
This study was conducted to determine the association between dietary calcium intake and biomarkers related to lipid and glucose metabolism and inflammation in Korean patients with type 2 diabetes. Seventy-five subjects (41 males, 34 females) were recruited from a group of patients who had visited the department of endocrine medicine. Data on anthropometric characteristics, clinical indices such as hemoglobin A1c and C-reactive protein (CRP), and dietary nutrient intakes were collected. Subjects were divided into three groups on the basis of their calcium intake [< EAR (below estimated average requirement), EAR-RNI (between EAR and recommended nutrient intake), > RNI (above RNI)]. Average calcium intake of < EAR, EAR-RNI, > RNI groups were $462.7{\pm}18.7$, $649.7{\pm}12.8$, and $895.7{\pm}21.7mg$, respectively. Energy intake was not different among groups but intakes of protein, total and saturated fatty acids were significantly higher in > RNI group than < EAR group. Analysis of covariance revealed that HDL cholesterol level was significantly higher in EAR-RNI group, as compared to < EAR group after adjustment with confounders such as age, sex, BMI and energy intake (p < 0.05). Levels of CRP and homeostasis model assessment 2-insulin resistance (HOMA2-IR) were significantly lower in EAR-RNI group. Total cholesterol level was higher in EAR-RNI and > RNI groups, although within the normal range. Our results suggest that dietary calcium intake may influence the levels of HDL-cholesterol, CRP and HOMA2-IR and subsequently, help management/treatment of type 2 diabetes patients.
This study was carried out to investigate Mg status and the relationship between dietary Mg the blood pressure in 30 healthy women, 26 to 57 year of age, living in rural area of Korea. Dietary intake of the subjects on self-selected diet were recorded. Duplicated food sample and 24-hour urine samples were collected for 3 days. Mean daily dietary Mg intake levels were determined by chemical analysis of duplicated food samples and mean daily urinary Mg excretion was measured from urine samples. Fasting serum Mg levels of each subjects was measured on the 3rd day of the survey. The results were as following: 1) The mean daily intakes of energy, protein were 1770.36㎉ and 55.55g, respectively. Carbohydrare, fat and protein supplied 77.1%, 10.4% and 12.5% of total energy intake. 2) The dietary Mg showed positive correlations with carbohydrate(P<0.05), vitamin A and vitamin B2(P<0.01), energy, Ca, P, fiber, vitamin B1 and niacin(P<0.001), but negative correlation with SBP(P<0.05). 3) The daily mean intake of Mg was 259.07$\pm$74.54mg and the urinary excretion of Mg was 75.48$\pm$33.14mg which was 29.5% of the dietary intake of Mg. And there was no significance between the dietary intake and the urinary excretion of Mg. 4) The dietary fiber showed negative correlations with SBP and DBP(P<0.05). 5) The serum and urinary concentrations of Mg were normal range and the serum Mg showed negative correlation with dietary vitamin C(P<0.05, r=-0.3655). It was concluded that the dietary Mg level of Korean rural women consuming self-selected diets was lower than that of RDA of American women but higher than that of RDA of Canadian. And the dietary intake levels of Mg and fiber, which are contained mostly in cereals and vegetables are useful to prevent hypertention.

Protein-energy malnutrition, PEM, and increased hs-CRP level are considered to be associated with increased risk of cardiovascular disease (CVD) in hemodialysis (HD) patients. This is commonly referred to as the vicious circle of malnutrition-inflammation-atherosclerosis cardiovascular disease (MIA syndrome) in chronic kidney disease (CKD). Low protein intake can decrease the serum level of albumin and increase inflammational markers; further, both low serum albumin and high hs-CRP are independent risk factors for all-cause mortality in HD patients. The aim of this study is comparing the serum levels of albumin and hs-CRP in HD patients according to the protein intake levels. The total number of subjects was 60 hemodialysis patients; they were grouped by dietary protein intake: low protein intake group (LPI, protein intake < 1.0 g/kg IBW, 11 men and 19 women) and adequate protein intake group (API, protein intake ${\geq}$ 1.0g/kg IBW, 12 men and 18 women). Blood biochemical parameters, nutrient intake, and dietary behaviors were compared between the LPI and API groups. The LPI group showed a significantly lower serum level of albumin and higher serum level of hs-CRP than the API group (p < 0.05). The LPI group showed a significantly lower intake of most nutrients than the API group (p < 0.05). Index of Nutritional Quality of most nutrients of the LPI and API groups were lower than 1.0. Dietary protein intake was positively correlated with the serum level of albumin (r = 0.306, p < 0.05) and negatively correlated with the serum level of hs-CRP (r = -0.435, p < 0.01). The serum level of hs-CRP was negatively correlated with that of albumin (r = -0.393, p < 0.01). According to these result, serum albumin and hs-CRP in HD patients were influenced by the protein intake levels. To prevent MIA syndrome, it is necessary to improve nutritional status, especially in protein and energy.

The effect of 16 different dietary rations, computed by the combinations of 13, 16, 19 or 22% CP and 2600, 2800, 3000 or 3100 kcal ME/kg, on growth performances and carcass yield of Starcross layers were assessed in two similar experiments. In both experiments, the body weight, eviscerated carcass yield, edible carcass yield, length of digestive tract and shank length increased but the feed intake decreased linearly with the increase of dietary CP and ME levels. The liver and gizzard weights as percentages of live weight tended to be increased with the increase of dietary CP and ME levels. The carcass dry matter, crude protein, fat, ash and energy content were not influenced by the dietary CP and ME levels. Dietary CP levels had positive correlations with all the parameters (except feed and energy intake and carcass dry matter). However, the dietary ME levels were positively correlated with all the parameters (except feed and energy intake; carcass dry matter and ash) in both experiments. The higher values were noted for all the parameters (except gizzard and carcass fat percentages) studied in Experiment 1 compared to those observed in Experiment 2.
A feeding trial was designed to assess the effects of dietary protein and lipid content on growth, feed utilization efficiency, and muscle proximate composition of juvenile mandarin fish, Siniperca scherzeri. Six experimental diets were formulated with a combination of three protein (35, 45, and 55%) and two dietary lipid levels (7 and 14%). Each diet was fed to triplicate groups of fish ($8.3{\pm}0.1g$) to apparent satiation for 8 weeks. The results showed that growth performance in terms of weight gain (WG) and specific growth rate (SGR) increased with increasing dietary protein level from 35 to 55% at the same dietary lipid level. At the same dietary lipid content, WG and SGR obtained with diets containing 55% protein was significantly higher than those obtained with diets containing 45 and 35% protein. No significant effect on growth rate was found when the dietary level of lipid was increased from 7 to 14%. While the levels of protein and lipid in the diets had no significant effect on feed intake, other nutrient utilization efficiency parameters including daily protein intake (DPI), feed efficiency (FE), and protein efficiency ratio (PER) showed a similar trend to that of growth rates, with the highest values obtained with diets containing 55% protein. Muscle chemical composition was not significantly affected by the different dietary treatments for each dietary lipid or protein level tested. These findings may suggest that a practical diet containing 55% protein and 7% lipid provides sufficient nutrient and energy to support the acceptable growth rates and nutrient utilization of mandarin fish juveniles.
This study estimated the status of dietary intake of 258 children from ages 3 to 6 living in Seoul and analyzed the correlation between the degree of children's nutrition awareness and dietary intake, to provide some basic informations on nutrition education program for their health promotion. Average height and weight of the children were 110.5 cm and 19.7 kg. And their body mass index was 16.2 and obesity index was 6.5%. Proportions of carbohydrate, protein and fat to the total calorie intakes were on the average 55.8%, 15.6% and 28.6%. Calorie intake proportion of breakfast, lunch, dinner and snack were 20.9%, 21.9%, 22.3% and 34.9%. In protein intake, proportion of animal and vegetable protein was 1.4, in fat intake pattern, P/M/S ratio was 1.2/1.2/1.0. As a consequence of analyzing the correlation between children's nutrition awareness and dietary intake, children of high awareness degree to the food value did not intake much calorie and carbohydrate, and did not choose cereals and starches, condensed fat food. As a result, dietary intake of pre-school children showed very good but partially showed a problem of over and under nutrition in quantity or in quality we hope that the result of this study could be helpful for the nutrition education program for the health and nutrition of the pre-school children.
The adequate dietary intake is important to maintain the nutritional status of the patients after pancreatic cancer surgery. This prospective study was designed to investigate the dietary intake and the nutritional status of the patients who had pancreatic cancer surgery. Thirty-one patients (15 men, 16 women) were enrolled and measured body weight, body mass index (BMI), nutritional risk index (NRI), and Malnutrition Universal Screening Tool (MUST). Actual oral intake with nutritional impact symptoms recorded on the clinical research foam at every meal and medical information were collected from electronic medical charts. The rates of malnutrition at admission were 45.1% (14/31) and 28.9% (9/31) by NRI and MUST method, respectively, but those were increased to 87% (27/31) and 86.6% (26/31) after operation on discharge. The median values of daily intake of energy, carbohydrates, fat, and protein were 588.1 kcal, 96.0 g, 11.8 g, and 27.0 g, respectively. Most patients (n = 20, 64.5%) experienced two or more symptoms such as anorexia, abdominal bloating and early satiety. There were negative correlations between C-reactive protein (CRP) levels and the intake of total energy, protein, fat, and zinc. The rates of malnutrition were increased sharply after surgery and the dietary intake also influenced the inflammatory indicators. The results suggested that need of considering special therapeutic diets for the patients who received pancreatic surgery.
To study the effects of the age and the dietary protein content on Ca metabolism male rats of 1 month 6 month 12 month of age were fed experimental diets containing 5%, 15% or 50% casein for 4 weeks. Food and ca intake were higher in old rats and in high protein groups. The weight ash and Ca contents of femur and tibia were higher in old rats. The higher dietary protein level resulted in higher skeletal weigh ash and Ca contents. But high protein diet(50% casein) lead to reduced bone mineral density(ash/dry bone weight) and Ca density(Ca/dry bone weight) in 1 month old rats. Low protein diet(5% casein) on the other hand reduced the bone growth even though the bone density was higher in this group. The ill effect of low protein diet was not evident in 12 month old rats. Glomerular filteration rate(GFR) and urinary Ca excretionincreased with age and with dietary protein level especially in 12 month old rats. Serum immunoreactive parathyroid hormone(iPTH) level tended to be higher in aged rats but was not affected by dietary protein level except 1 month old rats where 50% protein group showed significantly higher value. This study showed that the dietary protein level seemed to have different effect on Ca metabo-lism in rats of different age., The low bone density in the high protein group of growing rats may be due to the higher iPTH level and increased urinary Ca. The dietary protein level however had no effects on the bone composition in aged rats even though the higher urinary Ca excretion. In conclusion this study suggests that high protein intake from young may lead to less peak bone mass and to increase the bone loss in later years, which would increase the risk for osteporosis.

This study was conducted to obtain accurate data on intake, apparent digestibility and nitrogen balance of dietary protein which the korean take in habitually. Subjects were 8 male college students, aged from 20 to 26, and maintained their menu and life pattern as usual during a 4-week study. The same amount of diet that the subjects had consumped, and feces and urine were collected and measured to extract their nitrogen content data by Kjeldahl method. From above data, the apparent digestibility and the body nitrogen balance were estimated by determining daily protein intake and excretion. The daily protein intake measured by Jjeldahil method was 88.3$\pm$ 0.9g(1.45/kg of body weight /day) which marked 8.3% higher than that estimatd by food analysis table. The proportional of animal protein against total protein intake was 50.4$\pm$ 2.3%. Daily fecal protein loss was 14.3$\pm$0.6g and the apparent digestibility was 83.8$\pm$ 0.7%. The urinary nitrogen excretion was 10.30$\pm$0.19g. The nitrogen balance considering nitrogen excretion from feces indicated positive balance of 1.06$\pm$0.20g.
