Objectives: This systematic review of cohort studies aimed to identify any association between specific dietary patterns and risk of colorectal cancer (CRC). Dietary patterns involve complex interactions of food and nutrients summarizing the total diet or key aspects of the diet for a population under study. Methods and materials: This review involves 6 cohort studies of dietary patterns and their association with colorectal cancer. An exploratory or a posteriori approach and a hypothesis-oriented or a priori approach were employed to identify dietary patterns. Results: The dietary pattern identified to be protective against CRC was healthy, prudent, fruits and vegetables, fat reduced/diet foods, vegetables/fish/poultry, fruit/wholegrain/dairy, healthy eating index 2005, alternate healthy eating index, Mediterranean score and recommended food score. An elevated risk of CRC was associated with Western diet, pork processed meat, potatoes, traditional meat eating, and refined grain pattern. Conclusion: The Western dietary pattern which mainly consists of red and processed meat and refined grains is associated with an elevated risk of development of CRC. Protective factors against CRC include a healthy or prudent diet, consisting of vegetables, fruits, fish and poultry.

The ethanol extracts of the mixed vegetables (Bioactive Vegetables, BV) and the mixed fruits (Bioactive Fruits, BF) were evaluated for their in vivo antioxidant activities. Four weeks treatment of oral administration was performed to mice. A $KBrO_3$ as a potent oxidant was used to induce the oxidative stress for in vivo experiment. BV and BF were shown to possess the significant inhibitory effect of lipid peroxidation as measured by the level of malondialdehyde (MDA) formation although the potencies were not higher than those of well-known antioxidants such as vitamin C, trolox and quercetin. Furthermore, BV and BF inhibited DNA damage assessed by single cell gel electrophoresis (comet assay) and reduced the micronucleated reticulocyte (MNRET) formation of peripheral blood. Antioxidants tested also revealed potent inhibitory activities higher than BV and BF. These antigenotoxic activity profiles were similar to that of abovementioned inhibition of lipid peroxidation. Therefore, BV and BF having mild antioxidant activity as functional food candidates may be useful natural antioxidants by the inhibiting of lipid peroxidation and the protecting oxidative DNA and chromosomal damage.

Phenolic compounds in food and plant materials belong to the simple phenols, phenolic acids, coumarins, flavonoids, stilbenes, tannins, lignans and lignins, all of which are considered as secondary plant metabolites. These compounds may be synthesized by plants during normal development or in response to stress conditions. Phenolics are not distributed uniformly in plants. Insoluble phenolics are components of cell walls while soluble ones are present in vacuoles. A cursory account of phenolics of cereals, beans, pulses, fruits, vegetables and oilseeds is provided in this overview. The information on the bioavailability and absorption of plant phenolics remains fragmentary and diverse. Pharmacological potentials of food phenolics ave extensively evaluated. However, there are many challenges that must be overcome in order to fully understand both the function of phenolics in plant as well as their health effects.

The purpose of this study was to assess consumption and satisfaction with fresh-cut produce in Korean adults. In this study, an online survey November 9~13, 2020 was conducted with 982 Korean adults age 19~64 (490 males and 492 females) with experience in purchasing fresh-cut produce in the past year. Among all respondents, the percentage with experience in buying 'washed or peeled vegetables' was the highest (71.18%), followed by those in buying 'packaged salads/sprouts/ssam vegetables' (64.15%), 'pre-cut fruits/fruit cups' (59.98%), 'pre-cut or minced vegetables' (56.01%), and 'washed or peeled fruits' (53.67%), respectively. Among the types of fresh-cut produce, 'packaged salads/sprouts/ssam vegetables' showed the highest satisfaction score at 3.73 pts, and the overall satisfaction score of fresh-cut produce consumption was also 3.73 pts. Compared to male respondents, female respondents showed a significantly higher percentage of respondents that purchased 'packaged salads/sprouts/ssam vegetables' (p=0.0409), significantly higher satisfaction scores (p=0.0124), and a higher percentage of respondents considering 'freshness' important when purchasing (p<0.0001). Additionally, the group with high household income comprised a significantly higher ratio of respondents considering 'eco-friendly or organic status' important. The study results may facilitate identify areas for improvement of fresh-cut produce in the future.

Heavy metal pollution in agricultural field near at the abandoned metal mines has been a critical issue in Korea. In particular, bioaccumulation in plants can have detrimental effect on human health. Main objective of this research was to examine arsenic (As) concentration in soil with varied extraction methods and to determine bioaccumulation and biological transfer factor in different crops. Results showed that bioaccumulation ratio of As for total contents in soil was ordered leafy and stem vegetables (1.19%) > fruit bearing vegetables (0.79%) > pulses (0.40%) > root vegetables (0.36%) with different crop species. Among 6 different extraction methods, all of extraction methods showed high correlation ($R^2=0.87-0.97$) except DTPA ($R^2=0.25$) when comparing As concentration in soil extracted with different extractants and As concentration in each crops. Calculated biological transfer factor was ranged 0.002-0.018 depending on crop species. Overall, concentration of As in crops can be varied and best management practice for minimizing bioaccumulation of As should be considered depending on crop species.

The ascorbic acid contents of 101 food items were analyzed by HPLC to provide database to estimate dietary intakes of ascorbic acid of Korean. Foods with high contents of ascorbic acid were green vegetables, citrus fruits, strawberry, kiwi, and fruit juices. This analysis data of ascorbic acid contents in some food items showed significant deviations compared with other Food Composition Table. Ascorbic acid content in soups were lower than those of raw foods by about 57%. The ascorbic acid contents in blanched or seasoned after blanching vegetables and boiled or steamed meals turned out to be decreased by about 52.3% and 47.5%, respectively, but the degrees were varied with the kind of foods as well as cooking methods. The ascorbic acid intakes from 18 most frequently consumed meals in Korea were determined to be about 1/2 of Food Composition Table according to this analysis data. The results showed the importance of accurate food database in assessing nutrient intake levels of population.

Shock and vibration inputs are transmitted from the vehicle through the packaging to the fruit. Inside, these cause sustained bouncing of fruits against each other and container wall. These steady state vibration input may cause serous fruit injury, and this damage is particularly severe whenever the fruit inside the package is free to bounce, and is vibrated at its resonance frequency. The determination of the resonance frequencies of the fruit and vegetables may help the packaging designer to determine the proper packaging system providing adequate protection for the fruit, and to understand the complex interaction between the components of fruit when they relate to expected transportation vibration inputs. Instrumentation and technologies are described for determining the vibration response characteristics of the pears for exporting with frequency range from 10 to 200 Hz, sweep rate of 1 octave/min, sweep method of logarithmic up and down and acceleration levels of 0.2, 0.4, 0.6, 0.8 and 1.0 G considering the domestic transportation environment. The resonance frequency of the pears ranged from 49.04 to 87.16 Hz and the amplitude at resonance was between 0.96 and 4.02 G in test frequency band and acceleration level. The resonance frequency and amplitude at resonance frequency band of the pears decreased with the increase of the sample mass. The multiple nonlinear regression equations for predicting the resonance frequency of the pears were developed using the independent variables such as mass, input acceleration.

Agroforestry combines agriculture and forestry technologies to create more integrated, diverse, productive, profitable, healthy and sustainable land-use systems. This study was performed in three union of Chhagalnaiya Upazila (Sub-district; administrative entity) under Feni district, Southern Bangladesh with a view to identify the tree resources, utilization pattern and economic return of major fruit and timber tree species. Information collected from a total of 45 households ranging from marginal, small, medium and large categories. Number of plant species increased with the increase of homestead area. A total of 39 plant species were recorded from the homegarden, of which 23 were fruit and 16 were timber tree species. Considerable number of vegetables was also planted under the shade of the homestead trees. The investment analysis showed that average benefit-cost ratios were greater than one, net present values were positive and internal rate of returns were more than 10%. Long term investment on horticulture and timber tree species is highly profitable if species like Swietenia mahagoni and Tectona grandis, Spondias pinnata, Syzygium cumini and Areca catechu were planted.
