The introduction of genetically modified crops has raised concerns regarding safety issues over the insertion of foreign genes into plant genomes using recombinant DNA technology. Since 1991 in Japan, 29 foods and 6 food additives have been evaluated, based on the "Guideline for Safety Assessment", before these foods were marketed. The MHW, however, decided that safety assessment of such foods and food additives should be legally imposed. because soon such foods and food additives are expected to circulate globally and a new system for assessing safety of such foods and food additives at a pre-market stage is necessary, in order to avoid the distribution of any genetically modified foods that have had no safety assessment. The MHW published relevant announcements to amend existing regulations on 1 May 2000. "Standards for safety assessment of seed plant" is established based on a concept of substantial equivalence, and applicable to the products which are regarded as equivalent to the existing products used as foods and food additives. The characterization of the food products entails consideration of the molecular characterization. phenotypic and compositional characteristics, key nutrients and toxicants, and toxicity and allergenicity of the introduced proteins, and if there are indications of unintended effects of the modification, whether further safety testing (animal studies etc.) is needed should be considered. Safety and wholesomeness studies with whole foods should be care fully designed in order to avoid nutritional imbalances causing artifacts and uninterpretable results as was the case of Dr. Pusztaiis report. A case study of genetically modified soybeans (glyphosate-tolerant soybeans) on the immune system of rats and mice is shown. Chemical compositions were also compared with those of the non-GM soybeans. The studies failed to detect any differences in immuno-toxic activity.muno-toxic activity.

Functional food for prevention of chronic diseases is one of this century's key global challenges. Cancer is not only the first or second leading cause of death in China and other countries across the world, but also has diet as one of the most important modifiable risk factors. Major dietary factors now known to promote cancer development are polished grain foods and low intake of fresh vegetables, with general importance for an unhealthy lifestyle and obesity. The strategies of cancer prevention in human being are increased consumption of functional foods like whole grains (brown rice, barley, and buckwheat) and by-products, as well some vegetables (bitter melon, garlic, onions, broccoli, and cabbage) and mushrooms (boletes and Tricholoma matsutake). In addition some beverages (green tea and coffee) may be protective. Southwest China (especially Yunnan Province) is a geographical area where functional crop production is closely related to the origins of human evolution with implications for anticancer influence.

Cholesterol is prone to oxidation, which results in the formation of cholesterol oxidation products (COPs). This occurs because it is a monounsaturated lipid with a double bond on C-5 position. Cholesterol in foods is mostly non-enzymatically oxidized by reactive oxygen species (ROS)-mediated auto-oxidative reaction. The COPs are found in many common foods of animal-origin and are formed during their manufacture process. The formation of COPs is mainly related to the temperature and the heating time the food is processed, storage condition, light exposure and level of activator present such as free radical. The level of COPs in processed foods could reach up to 1-10 % of the total cholesterol depending on the foods. The most predominant COPs in foods including meat, eggs, dairy products as well as other foods of animal origin were 7-ketocholesterol, 7 α-hydroxycholesterol (7α-OH), 7β-hydroxycholesterol (7β-OH), 5,6α-epoxycholesterol (5,6α-EP), 5,6β-epoxycholesterol (5,6β-EP), 25-hydoxycholesterol (25-OH), 20-hydroxycholesterol (20-OH) and cholestanetriol (triol). They are mainly formed non-enzymatically by cholesterol autoxidation. The COPs are known to be potentially more hazardous to human health than pure cholesterol. The procedure to block cholesterol oxidation in foods should be similar to that of lipid oxidation inhibition since both cholesterol and lipid oxidation go through the same free radical mechanism. The formation of COPs in foods can be stopped by decreasing heating time and temperature, controlling storage condition as well as adding antioxidants into food products. This review aims to present, discuss and respond to articles and studies published on the topics of the formation and inhibition of COPs in foods and key factors that might affect cholesterol oxidation. This review may be used as a basic guide to control the formation of COPs in the food industry.

The purpose of this study was to develop children-friendly education materials based on food replicas for the dietary education of lower grade elementary students. Through a literature review on current dietary problems and dietary education for children, five education themes were chosen: balanced diet, seasonal food, traditional food, noodle culture, and making instant noodles. A total of 304 key food items for food replicas were selected based on the themes: six basic food groups (113 items), balanced meals (37 items), dietary habits (74 items), spring foods (13 items), summer foods (17 items), autumn foods (16 items), winter foods (11 items), Korean traditional foods (52 items), Korean native noodles (18 items), noodles from foreign countries (19 items), and making instant noodles (46 items). Next, a food replica database was developed consisting of name of the food, picture, size, ingredient, recipe, reference, and attached code. Powerpoint slides and teaching plans for all education themes were developed utilizing the food replicas in order to raise interest and understanding of serving size and intake amount. This research provides a basis for the development of food replicas as effective dietary education materials for elementary students and their use in extra-curricular activities, after school programs, community health centers, or food companies.

The purpose of this study was to examine the current status of patents related to dietary life of the elderly in Korea. Using Korea Intellectual Property Rights Information Service, patents registered between 2002 and 2013 were searched with the key words including 'elderly or the aged' and 'food, meal, or dietary life.' The search results showed 1,438 patents, and 500 patents meeting the research purpose were selected and analyzed. They were divided into two categories: 'patents on foods' and 'patents on products and services related to dietary life.' The former was further divided into four subgroups as follows: foods for health promotion, foods for disease prevention, foods for the people with difficulty in swallowing and masticating, and others. Also, the latter was divided into products or services. The results showed that patents on foods accounted for about 90%, of which the patents on foods for health promotion were ranked as the highest (40%). The number of patents on products and services related to dietary life was relatively small, indicating that the technology development has been focused on foods. Therefore, the technology for products and services related to dietary life should be actively developed as well as that for foods to improve the quality of life for the elderly in the future.

Background: Green tea extracts are approved as nonprescription drug and available as health functional foods, health foods, and beverages. Clinical information on the products is lacking. Methods: Information about the products on green tea nonprescription drugs was obtained from the website of the Korea Pharmaceutical Information Center. The Naver, i.e., a top ranking online search portal, was used for compiling the list of the health functional food products using key words of 'green tea catechin' on August 23, 2018. The recommended daily dosages of catechins were calculated as 30% of the total dried mass of green tea and about 50% of the catechins were considered as epigallocatechin gallate (EGCG). Results: A total of two types of nonprescription drugs containing green tea powder or extracts, nine health functional food products, and three types of health foods were found. The regulatory requirements of the EGCG exceeding 800 mg were reported to be associated with adverse effects of elevated liver enzyme. If consumers take several green tea products concurrently, such as nonprescription drugs with health functional foods or health foods, it could exceed the recommended amount of EGCG. Conclusion: The concurrent use of green tea products as nonprescription drugs, health functional foods, and healthy foods may lead to an increased exposure to EGCG. Pharmacists should be aware the availability of various types of green tea products and the potential risk of liver toxicity due to excessive consumption of EGCG.

The activation of consumption of environment-friendly agricultural processed foods means not only the growth of environment-friendly agriculture, but also the development of related industries. Therefore, it is necessary to identify and apply the needs and purchasing attributes of environment-friendly agricultural processed food consumers. For this, survey was conducted to adult men and women in their 20s and 60s and a total of 200 copies were used for empirical analysis. In this study, the average difference between importance-satisfaction for purchase attributes of environment-friendly agricultural processed food was verified, and the IPA Matrix was prepared based on this. As a result, in terms of purchasing importance and satisfaction, it was found that those with no experience in purchasing environment-friendly agricultural processed foods regarded product, price, place, promotion as more important than those with experience in purchasing. In case of IPA, product and price factors were all important and satisfactory regardless of purchasing experience. On the other hand, it was found that the key factors for promotion were neither important nor satisfied with consumers regardless of their purchasing experience. Therefore, it is mainly necessary to focus on marketing and mass media promotion. At the same time, various domestic and foreign best practices should be benchmarked and a 4P marketing strategy should be established and promoted.

The purpose of this study was to research the perception and concern of university students with regard to well-being, and how these affected their assessment and satisfaction of university dormitory foodservice. Therefore, a survey was administered to 328 college students that use a dormitory foodservice. The results of the survey are as follows: First, the more positive the self-centered and society-centered values in relation to well-being, the greater both the concern and will to practice well-being through the eating well-being foods. Second, the attitude toward well-being food was positively correlated with the taste, amount, temperature, appearance and shape of dishes. Third, unlike the will to practice well-being through the eating well-being foods, the greater the concern about foods of well-being, the more positive was the effect on the general satisfaction with the foodservice. The greater the satisfaction with the attributes of a foodservice had a substantial influence on the general satisfaction with the foods. That is to say, the taste and type of dishes played a key role in the general satisfaction with the foods. Fourth, the concern in relation to foods of well-being had no measurable influence on the decisions with regards to the satisfaction of a foodservice or on the intention to reuse that foodservice. In addition, in relation to the degree of satisfaction with the attributes and use of a foodservice, the taste, type, appearance and shape of dishes had an important impact on the decisions to use and reuse a foodservice. Fifth, the general satisfaction with the meals served by a foodservice operation had a measurable influence on the satisfaction with, and intention to reuse that foodservice.
