The purpose of this study was to compare convenience food purchasing behaviors and food habits. The study, which asked surveyed 131 female college students in Daejeon, in 2011, on how they used nutrition labels. The subjects were divided into two groups, in terms of the way they checked examined nutrition labels: a "Check" group(n=62, 47.3%) and a "No check" group(n=69, 52.7%). Reasons given for not reading nutrition labelings were "a habit of buying" for 72.2%, and "too small or rude" for 19.1%. The "Check" group reported higher interest in nutrition(p<0.001) and hygiene(p<0.01) than the "No check" group. Those who used the labels had higher cereal(p<0.01) and vegetable(p<0.01) consumption and a lower intake of fast foods(p<0.05). But however, most of the subjects(65.6%) chose by taste, at the time they purchased the convenience foods. The subjects considered "expiry date"(n=87, 66.4%) to be more important information on food labels than "nutrient composition"(n=11, 8.4%). The number of products whose nutrition labels were checked by over 50% was five out of 12. In conclusion, our study suggests that proper use of nutrition labeling may improve food choices and enable healthy dietary practices. Further efforts are needed to provide the public with nutrition education programs on how to read nutrition labeling. Modifying nutrition labels to make them easier for the public to understand should also be considered.

Polycyclic aromatic hydrocarbons (PAHs) are primarily formed as a result of thermal treatment of food, especially barbecuing or grilling. Contamination by PAHs is due to generation by direct pyrolysis of food nutrients and deposition from smoke produced through incomplete combustion of thermal agents. PAHs are ubiquitous compounds, well-known to be carcinogenic, which can reach the food in different ways. As an important human exposure pathway of contaminants, dietary intake of PAHs is of increasing concern for assessing cancer risk in the human body. In addition, the risks associated with consumption of barbecued meat may increase if consumers use cooking practices that enhance the concentrations of contaminants and their bioaccessibility. Since total PAHs always overestimate the actual amount that is available for absorption by the body, bioaccessibility of PAHs is to be preferred. Bioaccessibility of PAHs in food is the fraction of PAHs mobilized from food matrices during gastrointestinal digestion. An in vitro human digestion model was chosen for assessing the bioaccessibility of PAHs in food as it offers a simple, rapid, low cost alternative to human and animal studies; providing insights which may not be achievable in in vivo studies. Thus, this review aimed not only to provide an overview of general aspects of PAHs such as the formation, carcinogenicity, sources, occurrence, and factors affecting PAH concentrations, but also to enhance understanding of bioaccessibility assessment using an in vitro digestion model.

Northeastern India is a major nasopharyngeal carcinoma (NPC) high risk-area although the rest of the country has very low incidence. A case-control study of 105 NPC cases and 115 controls was conducted to identify the potential risk factors for NPC development in this region. Information was collected by interviewer about socio-demographic characteristics, cigarette smoking, alcohol consumption, dietary history, occupational history, and a family history of cancer. Epstein-Barr viral load was assayed from the blood DNA by real time PCR. Associations between GSTs genotypes, cytochrome P450 family including CYP1A1, CYP2E1 and CYP2A6 polymorphisms and susceptibility to relationship between the diseases were studied using PCR-RFLP assay. Results indicate that Epstein-Barr virus load was significantly higher in patients compared to controls (p<0.0001). Furthermore, concentration of blood EBV-DNA was significantly higher in advanced stage disease (Stage III and IV) than in early stage disease (Stage I and II) (p<0.05). Presence of CYP2A6 variants that reduced the enzyme activity was significantly less frequent in cases than controls. Smoked meat consumption, exposure to smoke, living in poorly ventilated house and alcohol consumption were associated with NPC development among the population of Northeastern India. Thus, overall our study revealed that EBV viral load and genetic polymorphism of CYP2A6 along with living practices which include smoked meat consumption, exposure to smoke, living in poorly ventilated houses and alcohol consumption are the potential risk factors of NPC in north eastern region of India. Understanding of the risk factors and their role in the etiology of NPC are helpful forpreventive measures and screening.

Incidence of breast cancer shows geographical variation, even within areas of ethnic homogeneity. Saudi Arabia has witnessed an increase in occurrence of breast cancer in its unexplored ethnic populations over the past few years. We aimed at determining whether any association exists between single nucleotide polymorphisms in breast cancer associated gene 1 (BRCA1) and breast cancer associated gene 2 (BRCA2) and the risk of breast cancer. TaqMan based Real Time Polymerase chain reaction genotyping assays were used to determine the frequency of single nucleotide polymorphisms in BRCA1 (rs799917) and BRCA2 (rs144848) in a group of 100 breast cancer patients and unaffected age matched controls of Saudi Arabian origin. The present data revealed that neither BRCA1 nor the BRCA2 studied variant show any significant association with the disease. This study failed to find any role of the concerned variants in breast cancer either as risk or as prognostic factors. The small number of patients registered was one of the limitations of this study. In summary, comparison of mutation profile with other ethnic populations and regions reflected both differences and similarities indicating co-exposure to a unique set of risk factors. The differences could be due to exposure to particular environmental carcinogens; different lifestyle, reproductive pattern; dietary or cultural practices of Saudi Arabian women that need further investigations.

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.

비만의 치료와 관리에 있어서 식이요법과 운동요법은 비교적 단기간의 효과는 입증 되었지만, 장기간 체중유지가 되지 못한다는 문제가 있다. 그래서 비만연구가들은 치료의 현장에서 행동수정요법을 활용한다. 그러나 행동수정요법의 식습관 및 생활습관 개선만으론 체중관리에 있어서 지속적인 결과유지는 여전히 큰 문제로 남아 있다. 그래서 본 연구에서는 기존 비만치료의 한계를 조금이나마 해결하고자, 행동수정요법의 장점에 인공지능을 활용한 비만관리를 제안한다. 인공지능 비만관리는 대상자들에게 인공지능으로 테이터화 된 문자메시지를 각자의 상황에 맞게 보내는 프로그램이다. 무엇보다도 인공지능 일대일 맞춤형 비만관리 메시지는 유연한 설득, 격려, 동기부여를 통한 운동지속의 효과를 강화시키는 연구 제안이다.

Effective parenting attitudes have been known to be associated with children's health practices including dietary intake and physical activity. The objective of this study is to compare children's body weights and eating habits by maternal parenting attitudes. Data were collected at school (N = 396; 4th and 5th grade students) using self-administered questionnaires on maternal parenting attitudes, eating habits and physical activity. Parenting attitudes were categorized as 1 of 4 parenting attitudes (overprotective, authoritarian, democratic, and neglectful) using affection and control median cut points. Children's body weights, frequency of breakfast, eating out and fastfood, and physical activity were compared by maternal parenting attitudes. Children's body weights were related with mother's employment status (p < 0.05) and parenting attitudes (p < 0.01). Children of unemployed mothers were more likely to be overweight. Children of neglectful mothers (p < 0.01) were more likely to be underweight, compared with children of mothers with other parenting attitudes. Since, unfortunately, the number of children of neglectful mothers was very limited in this study, we could hardly assess eating habits of children of neglectful mothers. Children of authoritarian mothers ate breakfast more regularly (p < 0.05), but ate snacks less regularly (p < 0.01). Children of democratic mothers ate fastfood less frequently (p < 0.01) and ate snacks more regularly (p < 0.01). Meanwhile, children of overprotective mothers ate breakfast less regularly (p < 0.05) and ate out less frequently (p < 0.01). However, maternal parenting attitudes were not related to children's physical activities. In conclusion, the maternal democratic parenting attitude was associated with healthy eating habits including regular snack time and less fastfood. On the other hand, the maternal neglectful parenting attitude was associated with high risk of children's underweight. Understanding the mechanism through which parenting attitude is related with underweight risk and healthy eating habits may lead to the development of better interventions.

The biological half-life and dissipation rate of azoxystrobin in crown daisy were calculated to establish the pre-harvest residue limits (PHRLs). The pesticide residues were calculated after washing with five different processes to propose an effective process in the household and conducted a risk assessment to confirm dietary safety. Azoxystrobin was sprayed according to the critical good agricultural practices (cGAP) in two different field trials, and the samples were harvested 7 times. The limit of quantitation was 0.02 mg/kg, and the mean recoveries of azoxystrobin were within the range of 70~120% with below 20% coefficient variation at the concentration of 0.02 and 0.2 mg/kg . The biological half-lives were 7.4 and 4.7 days, and the dissipation rate constants were 0.0872 and 0.1217 in fields 1 and 2, respectively. The average removal rates were 58.13~78.13% by the different washing processes, and there were significant differences between the washing processes (one-way ANOVA analysis and post-hoc Duncan test, p-value<0.05). The residues of azoxystrobin in crown daisy were safe levels from farm to fork after application with the critical good agricultural practice (cGAP) registered in Korea.
