Background: The aim of this study was to investigate demographic features, dietary habits, and some possible risk factors for being susceptible to breast cancer in Iranian women. Materials and Methods: A study of dietary habits and breast cancer was conducted among 53 Iranian women with histological confirmed disease and 40 matched controls. A dietary habits questionnaire was used to evaluate the pattern of selected food intakes. The risk of cancer was analyzed after adjustment for confounding factors. Age, weight, body mass index (BMI), waist circumference, educational status, parity, lactation, marital status, menopause, history of estrogen therapy, and family history of breast disease or cancer were assessed among participants. Special attention was given to the relationship between consumption of high fat meat, milk, yogurt and cheese as well use of frying oils for frying foods, use of olive/liquid oils for cooking, removing fat from meat and poultry, removing chicken skin and not use of mayonnaise as salad dressing and the risk of breast cancer. Moreover, salad, vegetable and fruit consumption, and eating outdoors owere investigated. Results: Our results revealed significant lower education and higher BMI and waist circumference levels in patients with breast cancer. There was significantly increased breast cancer risk in overweight women in comparison with normal weight (OR=2.91, 95%CI 1.24 to 6.82). High intake of fat dairy products including milk and cheese was found to be a statistically significant factor for increasing breast cancer risk in models adjusting for age, BMI and education. Use of olive/liquid oils for cooking and avoidance of mayonnaise as salad dressing are related to lower risk of breast cancer. The frequency of vegetable and fruit consumption was significantly lower in patients with breast cancer compared to healthy women. Conclusions: Dietary habits might be risk factors for breast cancer among Iranian women. Adoption of a prudent diet could be an appropriate strategy for preventing breast cancer.
Background: Colorectal cancer is one of the most commonly occurring cancers in China. Dietary fibre has been thought to decrease the risk of colorectal cancer in Western countries. However, studies investigating the association between dietary fibre (particularly soluble and insoluble fibres) and colorectal cancer have hitherto been lacking in China. Objective: This case-control study examined the effect of dietary fibre intake on the risk of colorectal cancer, stratified by tumour site. Materials and Methods: The study included 265 cases (colon cancer, 105; rectal cancer, 144; colon and rectal cancer, 16) and 252 controls residing in Qingdao. A food frequency questionnaire that included 121 food items was used to collect dietary information. Odds ratio (OR) and 95% confidence intervals (CI) were calculated using unconditional logistic regression analysis. Results: For food groups, controls in the study consumed more vegetables, soy food and total fibre than did colorectal cancer patients (p<0.05). The intakes of fruit, meat and sea-food did not differ significantly between cases and controls. However, we did not find any association between soy food intake and colon cancer. We observed inverse associations between total fibre intake and colorectal, colon and rectal cancer (Q4 vs Q1: OR=0.44, 95%CI, 0.27-0.73; OR=0.40, 95%CI, 0.21-0.76; OR=0.52, 95%CI, 0.29-0.91). Vegetable fibre intake showed similar inverse associations (Q4 vs Q1: OR=0.51, 95%CI, 0.31-0.85; OR=0.48, 95%CI, 0.25-0.91; OR=0.53, 95%CI, 0.29-0.97). In addition, inverse associations were observed between soluble fibre and insoluble fibre and both colorectal cancer and colon cancer. No relationship was found between colorectal cancer and fruit, soy or grain fibre intakewhen the results were stratified by tumour site. Conclusions: The present study suggests that vegetable fibre and total fibre play very important roles in protecting against colorectal cancer. Soluble and insoluble fibres were inversely associated with only colorectal cancer and colon cancer.

With the annual report of National Nutrition survey, the trend of food intake of Korean is analyzed from 1969 to 1989. Total food intake is about 1,000g. The amount of plant foods intake is decreased but the amount of animal food intake is increased. Among plant foods, the consumption of cereals and grain product and starch and starch roots is decreased gradually. The degree of decreasing are evident in the amount of cereal and grain product intake, The amount of vegetable intake is kept fluctuating, but the amount of processed vegetable products intake shows an upward trend. The amount of legumes and their products, vegetables, fruits and seaweeds intake is increased each year. In addition, among animal foods, the amount of meat and products, eggs, fish and shellfish and milk and milk products intake is increased greatly.

The lower elementary school grades are an important period in which eating habits are formed. We examined the relationship between eating habits and school meal intake in the lower grades of an elementary school in Seoul. The eating habits were investigated using the Nutrition Quotient (NQ) for children. The school meal intake rates and preferred menus were obtained by automatically scanning the plate before and after meals using an artificial intelligence food scanner. The average school meal intake rate for the 347 subjects was 68.5±12.2%, and the nutrient intakes through the school meals were 353.5±70.0 kcal of energy, 51.8±10.2 g of carbohydrates, 14.6±3.1 g of proteins, 10.3±2.3 g of fats, 87.0±20.0 mg of calcium, and 1.8±0.4 mg of iron. The preferred menus were rice, grilled food, and dairy products, and non-preferred menus were salad, beverages, and stewed food. The eating habits that showed a positive correlation with the school meal intake rate were 'Diverse side dishes (r=0.332, P<0.001)', 'Vegetable side dishes (r=0.166, P<0.01)', 'Kimchi side dish (r=0.230, P<0.001)' and 'Less TV watching and computer game time (r=0.105, P<0.05)'. The NQ score also showed a positive correlation with the rate of school meal intake (r=0.216, P<0.001). The balance score was positively correlated with fruit (r=0.192, P<0.001), and the diversity score had the highest positive correlation with Kimchi (r=0.362, P<0.001). The regularity score was positively correlated with fried food (r=0.114, P<0.05). In conclusion, it was found that elementary school students in the lower grades had a higher school meal intake rate when their eating habits included eating side dishes evenly, and consuming vegetable side dishes and Kimchi.
Purpose: This study evaluated the dietary quality of lunches consumed through home meals, institutional meals, and eating-out at restaurants in Chinese adults. Methods: The total of 3,708 people (aged 20 ~ 64) were selected from the data of the 2011 China Health and Nutrition Survey and divided into three groups: the home (HM, 2,845 people), institutional (IM, 579 people), and eating-out (EO, 284 people) meal groups. Dietary intakes of eight food groups, the frequency of eating certain foods, food group intake pattern, dietary diversity and the variety score of lunches were analyzed. Results: The meat intake of IM and EO were higher than that of HM (p < 0.05), and the vegetable intake was the highest in HM, followed by IM and EO (p < 0.05). The intake of fruit and milk·dairy products were extremely low in all the groups. Compared with 1/3 daily recommended intake, the meat intake was above the standard in all the groups and the vegetable intake was insufficient only in EO. The most frequently consumed food in all the groups was rice, followed by pork. The relatively desirable food group pattern, "grain + meat + vegetable", was highest in IM (66.0%) and lowest in EO (48.2%). The "grain + vegetable" pattern in HM and the "grain + meat" pattern in EO were relatively higher than that in the other groups. The dietary diversity score (p < 0.001) and dietary variety score (p < 0.001) were significantly higher in IM than that in the HM or EO. Conclusion: The lunches of Chinese adults had common problems in excess meat intake and a severe lack of fruit and milk·dairy products. Even institutional meals were not ideal as single meals for Chinese adults, although they were better in food diversity. Customized dietary educational programs based on balanced meal plans need to be established, especially for those Chinese people having lunch at home or eating out. In addition, a systematic food service program should be developed and firmly implemented.
This study was conducted to examine the effects of Na, K intake and stress level on the blood pressure and urinary excretion of Na, K in the third grade lacto-ovo vegetable male high school students. Twenty-one lacto-ovo vegetarian male high school students were selected, and their physical state, stress level, dietary intake and urinary excretion of Na, K were measured followed by examining the relationship among these factors and blood pressure. The results of the study can be summarized as follows : 1. The average age of the subjects was 17.7 years, and the average score of BMI was 20.4. The average score of Rohrer and blood pressure were 119.1, 112.3/7.5mmHg, each. All of these were in a normal range. Daily calorie intake was 2676.8kcal and Na, K intakes were 152.76mEq, respectively. 2. 71.4% of subjects were susceptible to the disease associated with stress, although there was no significant difference among the salt level, stress and blood pressure. 3. There was significant difference between dietary Na intake ratio, urinary Na excretion and urinary K excretion rate (p<0.001). 4. There was significant difference between systolic blood pressure and BMI/Rohrer score(p<0.01).

Nitrate is a naturally occurring compound in plant and can be converted to nitrite in the nitrogen cycle and vice versa. Therefore, it is easy to find nitrate in plants including vegetables. Especially, it is known that high levels of nitrate found in leafy vegetables. Nitrate itself is relatively non-toxic but its metabolites and reaction products such as nitrite, nitric oxide and N-nitroso compounds, may produce adverse health effects such as methaemoglobinaemia and carcinogenesis. To execute the risk assessment of dietary nitrate and nitrite for the intake of vegetables, it is investigated that the levels of nitrate and nitrite in 23 vegetables (798 samples). The range of concentration were 0-6,719mg/kg for nitrate and 0-1,635mg/kg for nitrite, respectively. The Estimated daily intakes (EDI) were 0.85-1.38 mg/kg body weight/day for nitrate and 0.02-0.03 mg/kg body weight/day for nitrite by ages. We conclude that there are no health concerns for eating various vegetables since the EDI were below the Tolerable Daily Intake (3.7 mg/kg body weight/day for nitrate, 0.06 mg/kg body weight/day for nitrite) level established by WHO.
To assess the nutrient intake and diet quality of Korean adults living in rural area, dietary survey with one day 24 -hour recall method was given to 2037 subjects over 30 years of age living in Yeoncho-gun, Kyungki province of Korea, together with health survey. The mean daily energy intake was 1583 kcal, with 65.4% of energy intake being supplied by carbohydrate, 15.9% by protein and 18.7% by fat. Eighty percents of total food intake were supplied by vegetable food and the rest in the form of animal food . As well as insufficiencies in calcium and iron intake, the bioabailability of calcium and iron is considered to have been low because most of those intakes came form plant origins. For most nutrients except phosporous, proportions of subjects with intake levels less than 75% of RDA was over 40% and highest in the elderly. Those proportion of low intake among female were higher than those among male. The mean adequacy ration(MAR) , an index of overall dietary quality was 0.62 for females and 0.68 for males and decreased with increase of age. The indexes of nutritional quality (INQ) were over 1 for most nutrients except 0.06 of vitamin A, 0.73 of calcium and 0.85 of vitamin C, Nutrient intake levels less than 75% of RDA may be appropriate as a criteria for insufficiency of nutrient intake. Based on these results, it is evident that some of adults in rural areas did not consume enough nutrients, especially vitamin A, calcium and vitamin B$_2$, and that the dietary intake of female and the elderly was not adequate .
The purpose of this study was to estimate the daily manganese (Mn) intake of Korean children. This study was done using a three-day dietary intake survey of 257 Korean children (boys 123; girls 134). The Mn intake values were calculated based on a database that provides the Mn content of the frequently consumed Korean foods, alongside the food composition table provided by the Korean National Rural Living Science Institute. The average age, height, weight and body mass index of our subjects were 11.9 years, 155.4 cm, 48.9 kg and 20.2 kg/$m^2$ in boys and 11.9 years, 154.1 cm, 43.5 kg and 18.3 kg/$m^2$ in girls. The average daily energy intakes were 2,249.2 kcal in boys and 2,044.5 kcal in girls. Boys consumed significantly more Mn than girls, based on intake estimates of $4,585.3{\mu}g$ (117.6% of adequate intake) and $4,029.3{\mu}g$ (117.1% of adequate intake), respectively (P < 0.001). Boys had a Mn intake of $2,041.1{\mu}g$ per 1,000 kcal of energy consumption, whereas for girls this was at $1,983.9{\mu}g$ per 1,000 kcal. Neither group exceeded the tolerable upper intake level for Mn. The major food groups which contributed to Mn intake in our subjects were cereals (50.8%), vegetables (21.0%), seasonings (8.9%), and pulses (7.7%). Notably, boys derived a higher Mn intake through cereals and vegetable than did girls (P < 0.001, P < 0.05). The key food sources of Mn, in descending order, were rice, soybean curd, kimchi, black rice and cereals. We propose that the results of our study may be used as a basis for follow-up studies that examine the Mn intake of children.
This study was to evaluate the effectiveness of the weight control program for female college students. The program was composed of diet and behavioral modifications for 8 weeks. A total of 78 participants enrolled the weight control program. Upon completion of the program, 53 participants experienced weight loss and 25 did not. The intakes of carbohydrate and fat were significantly decreased in both groups. However, the total diet quality index-international (DQII) scores as well as individual scores such as variety scores for protein source and adequacy scores for vegetable, fiber, calcium and vitamin C and moderation scores for empty calorie food were increased significantly in weight loss group only. In the weight loss group, weight, BMI, body fat, percent body fat and waist-hip ratio were decreased significantly. In addition, compared to the weight gain group, the weight loss group had higher changes in weight (weight loss group: -2.6% vs weight gain group: 1.5%, p < 0.001), body fat (-6.0% vs 0.0%, p < 0.001), percent body fat (-3.1% vs -0.3%, p < 0.001), waist-hip ratio (-1.0% vs 0.5%, p < 0.001) and BMI (-2.6% vs 1.3%, p < 0.01). There was no difference in blood profiles between the two groups. The changes in DQI-I scores were significantly correlated with the changes in body weight (r = -0.239, p < 0.05) and BMI (r = -0.224, p < 0.05), indicating that effective nutrition education could help improve diet quality leading to successful weight management among female college students.
