Objectives: This study examined the perception of the vegan trend of millennials and their future needs. Methods: This study was conducted online from June 21, 2021, to July 15, 2021, targeting 425 adult men and women born between 1980 and 2000. The contents of the survey were divided into four categories: general information, awareness of vegetables, awareness of vegan trends, and future needs for vegan trends. Results: Most respondents recognized the importance of eating vegetables and perceived vegetarianism and veganism as a lifestyle. Regarding the perception of the vegan trend, the highest response rate was 'The vegan trend is to be satisfied with my life regardless of other people', while the lowest response rate was 'The vegan trend is only a temporary fad'. The reasons for purchasing vegan products with high response rates were 'interest in the earth and environment', 'protection of animal rights', and 'thinking about health'. The type of vegan product wanted in the future was delicious food, and convenience level was in the order of 'completely cooked', 'half-cooked', and 'pre-processed'. Among the sustainable vegetarian types that millennials responded, 'semi-vegetarian', which can consume most animal products excluding red meat, showed the highest response rate. Conclusions: The positive perceptions about vegetables are expected to increase. Efforts should be made to develop convenient meals using vegetables and provide reasonable prices to expand vegetable intake.

Pyrosequencing analysis of intestinal microflora from healthy Thai vegetarians and non-vegetarians exhibited 893 OTUs covering 189 species. The strong species indicators of vegetarians and non-vegetarians were Prevotella copri and Bacteroides vulgatus as well as bacteria close to Escherichia hermanii with % relative abundance of 16.9 and 4.5-4.7, respectively. Core gut microbiota of the vegetarian and non-vegetarian groups consisted of 11 and 20 different bacterial species, respectively, belonging to Actinobacteria, Firmicutes, and Proteobacteria commonly found in both groups. Two species, Faecalibacterium prausnitzii and Gemmiger formicilis, had a prevalence of 100% in both groups. Three species, Clostridium nexile, Eubacterium eligens, and P. copri, showed up in most vegetarians, whereas more diversity of Collinsella aerofaciens, Ruminococcus torques, various species of Bacteroides, Parabacteroides, Escherichia, and different species of Clostridium and Eubacterium were found in most non-vegetarians. Considering the correlation of personal characters, consumption behavior, and microbial groups, the age of non-vegetarians showed a strong positive correlation coefficient of 0.54 (p = 0.001) to Bacteroides uniformis but exhibited a moderate one to Alistipes finegoldii and B. vulgatus. Only a positive moderate correlation of body mass index and Parabacteroides distasonis appeared. Based on the significant abundance of potential pathogens, the microbiota of the non-vegetarian group showed an abundance of potential pathogen varieties of Bilophila wadsworthia, Escherichia coli, and E. hermannii, whereas that of the vegetarian group served for only Klebsiella pneumoniae. These results implied that the microbiota of vegetarians with high abundance of P. copri and low potential pathogen variety would be a way to maintain good health in Thais.

Infants and children with food related Atopic Dermatitis (AD) need extra dietary efforts to maintain optimal nutrition due to food restriction to prevent allergy reactions. However, nutrition ignorance and food faddism make patients even more confused and practice desirable diet more difficult. The objective of this study was to report the AD patients' malnutrition cases in Korea. We report on 2 cases of severe nutritional deficiency caused by consuming macrobiotic diets which avoid processed foods and most animal foods, i.e. one of vegetarian diet. Case 1, a 12-month-old male child, was admitted with severe marasmus. Because of a history of AD, he was started on mixed grain porridge at 3 months without any breast milk or formula feeding. His caloric intake was 66% and protein intake was 69% of the recommended dietary allowance. Patient's height and weight was under 3th percentile. On admission the patient was unable to crawl or roll over. Case 2, a 9-month-old AD female patient, was diagnosed with kwashiorkor and rickets. She was also started on mixed grain porridge at 100 days due to AD. Her caloric intake has been satisfied recommended dietary allowance until 7 months, however, she conducted sauna bath therapy and reduced both energy and protein intake at 8 months. The amount of protein intake for case 2 was higher than recommended dietary allowance, but, sauna therapy and severe AD with intakes of low guality protein may increase patient's protein requirement resulting in kwashiorkor. Case 2 patient's height and weight was on 3th percentile. Both cases showed low intake of calcium, iron, zinc, vitamin A, vitamin E and especially very low intake of vitamin B$_{12}$ and vitamin D. Allergy tests for certain foods had not done prior to admission for both cases. They followed the dietary advise operated by macrobiotic diet internet site. In conclusion, AD infants' parents and caregivers should contact a pediatrician trained as a specialist in allergy for accurate diagnosis. For infant patients, breast or formula feeding including hypoallergenic formula should be continued until their one year of age. When certain foods need to be restricted or to follow special diets such as vegetarian diet, consultation with pediatrician and dietitian is needed.d.

The purpose of this study is to verify nutrient intake status and prevalence of obesity in vegetarians non-vegetarians and non-vegetarians. The vegetarian subjects consisted of 127 Buddhist nuns(age:23-79 yrs) from Oonmoon Temple on the Choungdo District of Gyeongsang Bookdo Province and 118 Buddhist nuns practicing Zen meditation at Soodeok Temple in Yeosan District of Chongcheong Namdoo Province. Control subjects were 235 healthy female adults aged from 23 to 79 years old. They were teachers and nurses at the hospital of Gyeongsang National University and housewives living in Chinju, Gyeingsang Namdoo Province. The study was conducted from October 1996 to February 1997, and consisted of a survey and anthropometric measurement. The results are summarized as follows : The average age of the subjects was 44.2 yrs for vegetarians and 40.5 yrs for non-vegetarians. The average body mass index(BMI) of vegetarians and non-vegetarians was 22.4 and 21.0, the waist hip ratio(WHR) was 0.8 and 0.8, and the percentage of body fat was 28.7 and 26.5 respectively. The average duration of vegetarian diet among vegetarians was 13.1 years. The nutrient intakes of vegetarians were above the RDA for all the nutrients expect calcium and vitamin A. The intakes of fat, cholesterol, saturated fatty acid and the energy ratio from fat among the vegetarians were significantly lower than those of the non-vegetarians(p〈0.01). However, the vegetarians consumed significantly higher amounts of fiber and vitamin C compared to the non-vegetarians(p〈0.01). Also, the ratio of dietary polyunsaturated fatty acid/saturated fatty acid was significantly higher in vegetarians. The prevalence of obesity was 13.9% for vegetarians and 11.9% for non-vegetarians by criteria of BMI 25 as obese.

Objectives : To assess the seroprevalence and risk factors of toxoplasmosis in high school students in Cheju Province, Korea. Methods : A total of 4,570 high school students from 18 schools in Cheju Province were investigated for Toxoplasma gondii antibodies(IgG) by enzyme linked immunosorbent assay (ELISA). Risk factors for toxoplasmosis, such as place of residence, type of house, contact with cats and other pets, and rare meat consumption, were examined by questionnaire. Results . The overall antibody positive rate was 5.5% and ranged from 2.6 to 11.5% by school. There was no significant difference between males and females. Statistical analyses of the questionnaire data indicated that the risk factors for seropositivity were: (1) birth place (Cheju/others), (2) place of residence (rural/urban), (3) dietary habits (vegetarian/non vegetarian), (4) eating rare meat, (5) exposure to pets and (6) hepatitis B. Conclusion : We confirmed that the prevalence of the anti-Toxoplasma gondii antibody in a population of high school students in Cheju Province was to the previously reported prevalence.
