  • Aim: The incidence of biliary tract cancer (BTC) is many-fold higher for American Indians (AI) relative to non-Hispanic whites (NHW). Neither gallstones nor genetics can account for this difference. There is speculation that certain fatty acids in bile may play a role in preventing BTC. Since diet may influence composition of bile, we compared the dietary intakes of urban AI and NHW adult women in New Mexico. Methods: Design, a cross-sectional study of the diets of lactating AI and NHW women was conducted. Setting, the University of New Mexico Hospital. Participants, healthy lactating women 18 to 39 years of age were recruited. Main outcome measures, a three-day diet record for each participant was analyzed. Results: The AI women consumed less calcium (p = 0.04) and significantly less short and intermediate chain-length fatty acids (C4-C12), but nearly twice as much proinflammatory arachidonic acid as the NHWs (p <0.01). The intake of dairy products by AI women was less than NHW women (p = 0.01) while the intake of processed meat products was higher (p <0.01). Conclusion: Dietary factors may account for the difference in the risk of BTC between AI and NHW women.

  • In this research, we examined the shifts in determinants influencing the frequency of eco-friendly food purchases pre- and post-COVID-19. Our analysis utilized filtered 2019-2021 Consumption Behavior Survey data from the Korea Rural Economic Institute Food, excluding any irrational responses. Given the nature of the dependent variable, a multinomial logistic regression model was employed with demographic factors, variables pertaining to food consumption behavior, and variables concerning food consumption awareness as predictors. Following the onset of the COVID-19 pandemic, an individual's level of education was observed to positively influence the frequency of eco-friendly food purchases. In contrast, income level and fluctuations in food consumption expenditure did not appear to have a discernible impact on the purchasing frequency of such eco-friendly products. Irrespective of the advent of COVID-19, variables such as the frequency of online food purchases, the utilization of early morning delivery services, dining out frequency, and the intake of health-functional foods consistently demonstrated a positive correlation with the propensity to purchase eco-friendly foods. Overall, consumers prioritizing safety, quality, and nutrition over price, taste, and convenience in their procurement decisions for rice, vegetables, meat, and processed foods exhibit an increased inclination toward the acquisition of eco-friendly food products.

  • This study was conducted to investigate the effect of various natural ingredients for manufacturing meat products on the $D_{10}$ value and relative radiation sensitivity (RRS) of foodborne pathogens inoculated into ground beef. The pathogens used for this study were Salmonella Typhimurium (KCTC 1925), Escherichia coli (KCTC 41682), Listeria monocytoges (KCTC 3569), and Staphylococcus aureus (KCTC 11764), and the natural ingredients added into ground beef were garlic, onion, black pepper, hot pepper, ginger, green onion, carrot, and red wine. The $D_{10}$ of E. coli was decreased significantly by 5% of garlic addition (RRS=1.460), and the addition of carrot (RRS=1.086) and red wine (RRS=2.864) also showed similar results. Most natural ingredients were effective in increasing radiation sensitivity of L. monocytogens, but only garlic, onion, hot pepper, carrot, and red wine were effective against S. aureus. In particular, the addition of red wine to ground beef showed the greatest increase of radiation sensitivity for 3 pathogens tested in the present study, except for S. Typhimurium. Results indicate that the use of certain natural ingredients for manufacturing processed meat products may have effects in the increase of radiation sensitivity of pathogens. This increased radiation sensitivity can reduce the target irradiation dose for obtaining the same level of safety, resulting in lowering the adverse quality changes caused by a high-dose irradiation process.

  • Dry hams and sausages we re processed manually under the environmental conditions in Seoul, Korea, by addition with $NaNO_2$ - equivalent of 264ppm and 185ppm, respectively. The residual nitrites levels throughout the processing and storage periods were 32-67 ppm which are below the maximum legal allowance of 70ppm . The nitrites showed the highest levels at 2- weeks processing of dry sausages and at 5-weeks processing of dry hams, and the levels were gradually decreased thereafter. The residual nitrites in sausages dried in intestinal cases were lower and dropped below 10ppm after 3-weeks processing. The dry hams processed in summer also contained lower levels of nitrites, below 10ppm after 4-weeks processing. The levels of residual nitrates, however, showed highest when that of nitrites were lowest and were increased gradually with the duration of storage.

  • The purpose of this study was to examine food habits and dietary behavior related to using processed food among male college students residing in dormitory and self-boarding in Gangwon. A total of 344 students (dormitory group: 227, self-boarding group: 117) were surveyed from May to June of 2012. The results are summarized as follows: self-boarding group had a significantly higher frequency of skipping breakfast and lunch and frequency of out meal compared with the dormitory group (p < 0.05, p < 0.05, p < 0.05 respectively). The self-boarding group had a significantly lower the score of 'eat vegetables and Kimchi at every meal' (p < 0.001) and 'eat a variety of food everyday' (p < 0.001) compared with the dormitory group. The self-boarding group had a significantly higher the preference for meat products (p < 0.05) and canned food (p < 0.01) for selecting processed food compared with the dormitory group. The consideration for selecting processed food was ranked by 'taste', 'price', 'expiration', 'appearance' and 'nutrition' in both dormitory and the self-boarding group. In the dormitory group, nutrition labels were identified certainly 2.6%, sometimes 12.8%, and rarely 17.2%. In the self-boarding group, nutrition labels were identified certainly 1.7%, sometimes 18.0%, and rarely 24.8%. The necessity of nutrition education was high in both dormitory group (51.6%) and the self-boarding group (62.4%). Therefore, development of an educational program and application of the information from nutrition labels for male college students, especially self-boarding students will be effective in improving dietary life in order to maintain healthy dietary habits.

  • This study was performed to develop an analytical method using Carrez reagents as the precipitant to effectively and easily remove proteins and lipids while pretreating samples for the simultaneous determination of preservatives, including dehydroacetic acid (DHA), sorbic acid (SA), benzoic acid (BA), methyl ρ-hydroxybenzoate (MP), ethyl ρ-hydroxybenzoate (EP), propyl ρ-hydroxybenzoate (PP), isopropyl ρ-hydroxybenzoate (IPP), butyl ρ-hydroxybenzoate (BP), and isobutyl ρ-hydroxybenzoate (IBP). The effective selectivity was determined by HPLC separation analysis for nine preservatives in the test solution, after removing interfering materials such as lipids and proteins. The method developed in this study showed excellent linearity at 0.999 or higher. The limit of detection (LOD) ranged from 0.09 to ~0.12 mg/L and the limit of quantitation (LOQ) was ~0.280.37 mg/L. The results of the recovery test on processed foods, including pickles, cheeses, processed meat products, beverages, sauces, and emulsified foods showed DHA, SA, BA, MP, EP, IPP, PP, IBP, and BP at 90.9~107.7 %, 85.4~113.7 %, 90.7~111.6 %, 84.5~111.2 %, 81.3~110.9 %, 82.5~102.2 %, 81.1~110.0 %, 80.9~109.0 %, and 82.4~110.3 %, respectively. The probability of the simultaneous analytical method developed in this study as a quantitative method was confirmed for various processed foods.

  • Agriculture has played a significant role in the national economy, contributing to food security, driving economic growth, and safeguarding the dietary habits of the population. Korean agriculture has been compelled to focus on intensive farming due to its limited cultivation area, excessive input costs, and the limitations of agricultural mechanization. In the Republic of Korea (R.O.K), the concept of environmentally friendly animal agriculture began to be introduced in the early 2000s. This concept ultimately aims to cultivate sustainable animal agriculture (SAA) through environmentally friendly production practices, ensuring the healthy rearing of animals to supply safe animal products. Despite the government's efforts, there are still significant challenges in implementing environmentally friendly agriculture and SAA in the R.O.K. Therefore, the objective of this review is to establish the direction that the animal agriculture sector should take in the era of climate crisis, and to develop effective strategies for SAA tailored to the current situation in the R.O.K by examining the trends in SAA in the U.S. The animal agriculture sector in the U.S. has been working towards creating a SAA system where humans, animals, and the environment can coexist through government initiatives, industry research, technological support, and individual efforts. Efforts have been made to reduce emissions like carbon, and improve factors affecting the environment such as the carbon footprint, odor, and greenhouse gases associated with animal agriculture processes for animals such as cattle and pigs. The transition of the U.S. towards SAA appears to be driven by both external goals related to addressing climate change and the primary objectives of responding to the demand for safe animal products, expanding consumption, and securing competitiveness in overseas export markets. The demand for animal welfare, organic animal products, and processed goods has been increasing in the U.S. consumer market. A major factor in the transformation of the U.S. animal agriculture sector in terms of livestock specifications is attributed to environmentally friendly practices such as high-quality feed, heat stress reduction, improvements in reproductive ability and growth period reduction, and efforts in animal genetic enhancement.

  • Background: Prostate cancer is the most frequently occurring cancer among males in economically developed countries. Among the several risk factors that have been suggested, only age, ethnicity, diabetes, and family history of prostate cancer are well-established and primary prevention of this disease is limited. Prior studies had shown that dietary intake could be modified to reduce cancer risk. We conducted a hospital-based, casecontrol study to examine the association between dietary patterns and prostate cancer risk in Iran. Materials and Methods: A total of fifty patients with prostate cancer and a hundred controls underwent face-to-face interviews. Factor analysis was used to determine the dietary patterns. Multivariate logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). Results: We defined two major dietary patterns in this population: 'western diet'(high in sweets and desserts, organ meat, snacks, tea and coffee, French fries, salt, carbonated drinks, red or processed meat) and 'healthy diet' (high in legumes, fish, dairy products, fruits and fruit juice, vegetables, boiled potatoes, whole cereal and egg). Both Healthy and western pattern scores were divided into two categories (based on medians). Higher scores on Healthy pattern was marginally significantly related to decreased risk of prostate cancer (above median vs below median, OR =0.4, 95%CI=0.2-1.0). An increased risk of prostate cancer was observed with the higher scores on the Western pattern (above median vs below median, OR=4.0, 95%CI=1.5-11.0). Conclusions: The results of this study suggested that diet might be associated with prostate cancer among Iranian males.

  • This study was performed to obtain basic data regarding the development of fish steak products using olive flounder and pork leg. Olive flounder and pork leg were ground separately in a chopper. The methods used for processing were as follows. Chopped olive flounder (100 g) and other ingredients (bread crumbs, 13 g; onion, 12 g; garlic, 4 g; egg wash, 18 g; salt, 0.05 g; pepper, 0.05 g) were mixed in a chopper. The mixture was molded into a steak shape ($12{\times}7cm$) and roasted in an oven at $180^{\circ}C$ for 12 min (OF). FP consisting of a mixture of olive flounder (70 g) and pork leg meat (30 g) and OP consisting of pork leg meat alone (100 g) were processed according to the same procedure as described for OF. Various factors (viable bacterial count, chemical composition, pH, salinity, hardness value, color value, total amino acid content, free amino acid content, fatty acid composition, mineral content) were measured, and sensory evaluation was conducted. Based on the results of the sensory evaluation and hardness value, OP was deemed to be the most desirable, followed in order by FP and OF. There was a slight but significant difference between OP and FP.

  • BACKGROUND/OBJECTIVES: Mediterranean diet is an environmentally friendly and healthy diet model. The diet offers many vegetables, fruits, nuts, and olive oil to consumers. In addition, it provides moderate amounts of fish and chicken, smaller quantities of dairy products, red meat, and processed meat. The Mediterranean diet has a high anti-inflammatory and antioxidant content, and it causes many physiological changes that can provide a physical performance advantage. This study examined the effects of a 15-day menu, which was planned using foods with a low acid load within the Mediterranean diet rules, on the exercise performance, lactate elimination, anthropometric measurements, and body composition. SUBJECTS/METHODS: Fifteen professional male athletes between the ages of 13 and 18, who were engaged in ski running, were included in the experimental study. Dietary intervention was applied for 15 days. The athlete performances were evaluated by applying the vertical jump test, hand grip strength, 20 meters shuttle run test, and Borg fatigue scale. After the shuttle run test (every 3 min for 30 min), blood was drawn from the finger, and the lactate elimination time was calculated. Performance and lactate measurements, body analysis, and anthropometric measurements were taken before and after dietary intervention. RESULTS: The vertical jump height and hand grip strength increased after the intervention (P < 0.05). The test duration, total distance, the number of shuttles, and maximum oxygen consumption parameters of the shuttle run test increased (P < 0.05). After the intervention, the athletes' perceived fatigue scores decreased in several stages of the shuttle run test (P < 0.05). The lactate elimination time and athlete's body composition were similar in repeated measurements (P > 0.05). In the last measurements, the upper middle arm circumference decreased while the height of the athletes increased (P < 0.05). CONCLUSIONS: These results show that the Mediterranean diet is a safe and feasible dietary approach for aerobic performance and strength increase.
