ABSTRACT
RESUMEN: Hace aproximadamente once mil años el ser humano pasó de alimentarse de los animales que cazaba o pescaba y los frutos y plantas que recolectaba, a aquellos que podía crecer a voluntad mediante la agricultura. Este cambio alteró dramáticamente la forma de la cabeza ósea y particularmente de la cara, que se hizo más grácil, y además se redujo el aporte de nutrientes claves. Con la industrialización, hubo un gran deterioro de la salud oral. Al abandono de una dieta cazadora recolectora incluso se le ha atribuido el origen de maloclusiones dentales, debido a la reducción del estrés masticatorio y con ello un menor tamaño relativo del maxilar y la mandíbula respecto a los dientes. Hoy en día, existiendo una mayor conciencia de la población respecto de sus cuidados y de su entorno, la adopción de dietas que excluyen cierto tipo de alimentos como los animales ha ganado adeptos. La dieta vegetariana presenta varias características que pueden afectar el metabolismo general y el óseo en particular, de manera similar a como lo hizo la agricultura en el pasado. La presente revisión busca analizar los cambios de la dieta humana, del punto de vista nutricional y mecánico y cómo estos afectaron la forma de la cara. Esto con el objetivo de comprender los posibles efectos de la introducción de alimentaciones de tipo restrictivas, como la vegetariana, en el organismo y particularmente en la anatomía facial.
SUMMARY: Approximately eleven thousand years ago humans beings went from feeding on animals they hunted or fished and fruits and plants they gathered, to crops they could grow through agriculture. This change dramatically altered the shape of the skull, particularly the face, which became more gracile, and also reduced the contribution of key nutrients. Along with industrialization, there was great deterioration of oral health. Leaving behind the hunter-gatherer diet has even been attributed to the origins of dental malocclusions, as masticatory stress was reduce, and reducing the size of the maxilla and mandible with respect to the teeth. Nowadays, there is greater awareness in the general population regarding personal care and their surroundings. Diets that exclude certain types of foods such as animal products are becoming more prevalent. The vegetarian diet has several characteristics that can affect metabolism, particularly the bones, as did the change from hunter-gatherer to agriculture in the past. The present review seeks to analyze the changes of the human diet, from the nutritional and mechanical point of view and how these have affected the shape of the face. This in order to understand the possible effects of the introduction of restrictive type feeds, such as the vegetarian diet in the body, particularly in facial anatomy.

PURPOSE: This cross-sectional study aimed to document the dietary behaviors, dietary changes, and health status of female marriage immigrants residing in Gwangju, Korea. METHODS: The survey included 92 female immigrants attending Korean language class at a multi-cultural family support center. General characteristics, health status, anthropometric data, dietary behaviors, and dietary changes were collected. RESULTS: Mean age of subjects was 31.3 years, and home countries of subjects were Vietnam (50.0%), China (26.0%), Philippines (12.0%), and others (12.0%). Frequently reported chronic diseases were digestive diseases (13.2%), anemia (12.1%), and neuropsychiatry disorder (8.9%). Seventeen percent of the subjects was obese (BMI ≥ 25 kg/m²). Dietary score by Mini Dietary Assessment was 3.45 out of 5 points. Dietary scores for dairy foods, meat/fish/egg/bean intake, meal regularity, and food variety were low, and those for fried foods and high fat meat intake were also low. Thirty-three percent of subjects answered that they have changed their diet and increased their consumption of fruits and vegetables after immigration. Length of residence in Korea was positively associated with BMI and waist circumference. Length of residence tends to be positively associated with dietary changes and obesity as well as inversely associated with disease prevalence. CONCLUSION: The study shows that length of residence is inversely related to disease prevalence. However, this association is thought to be due to the relatively short period of residence in Korea and thus the transitional phase to adapting to dietary practices. As the length of residence increases, disease patterns related to obesity are subject to change. Healthy dietary behaviors and adaptation to dietary practices in Korea in female marriage immigrants will not only benefit individuals but also their families and social structure. Therefore, varied, long-term, and target-specific studies on female marriage immigrants are highly needed.

BACKGROUND/OBJECTIVES: The immigrant population has grown considerably in South Korea since the early 1990s due to international marriages. Dietary changes in immigrants are an important issue, because they are related to health and disease patterns. This study was conducted to compare changes in dietary intake between baseline and follow-up periods. SUBJECTS/METHODS: Two hundreds thirty three Vietnamese female married immigrants. Baseline data were collected during 2006-2009, and the follow-up data were collected during 2008 and 2010. Food consumption was assessed using a 1-day 24-hour recall. RESULTS: The amount of the total food consumed (P < 0.001) including that of cereals (P = 0.004), vegetables (P = 0.003), and fruits (P = 0.002) decreased at follow-up compared to that at baseline, whereas consumption of milk and dairy products increased (P = 0.004). Accordingly, the overall energy and nutrient intake decreased at follow-up, including carbohydrates (P = 0.012), protein (P = 0.021), fiber (P = 0.008), iron (P = 0.009), zinc (P = 0.006), and folate (P = 0.002). Among various anthropometric and biochemical variables, mean skeletal muscle mass decreased (P = 0.012), plasma high density lipoprotein-cholesterol increased, (P = 0.020) and high sensitivity C-reactive protein decreased at follow-up (P < 0.001). CONCLUSIONS: A long-term follow-up study is needed to investigate the association between changes in food and nutrient intake and anthropometric and biochemical variables in these Vietnamese female marriage immigrants.

The purpose of this study was to analyze the nutritional status of Chinese female college students in Korea, and to investigate changes in their dietary behavior after residing in Korea. The subjects included 114 Chinese female college students currently studying in Korea. General characteristics and dietary behaviors before and after residing in Korea were investigated. Daily nutrients and food intake were assessed using a one-day 24-hour recall. Consumption of most nutrients, namely calcium, iron, zinc, vitamin B2, vitamin C, and folate was estimated to fall below the EAR for the Korean population. The proportions of subjects whose intake were estimated below the EAR for folate, calcium, vitamin B2, iron, zinc, and vitamin C were 93.0%, 71.9%, 66.7%, 65.8%, 65.8%, and 63.2%, respectively. In the current study, the dietary behavior scores fell significantly after Chinese students immigrated to Korea (p < 0.001); increased frequency of meal skipping, less consumption of fruits and vegetables, irregular meal pattern, and imbalanced diet were some of the significant changes among Chinese students before and after residing in Korea. In addition, consumption of most nutrients, including dietary fiber, vitamin A, vitamin B group, vitamin C, and folate in the Worsened Group was significantly lower, compared with the No Change Group (p < 0.05). According to the changes in dietary behaviors, consumption of most nutrients, including dietary fiber, vitamin A, vitamin B group, vitamin C, and folate in the Worsened Group was significantly lower than in the No Change Group (p < 0.05). In conclusion, these results indicated that Chinese students practiced more unhealthy dietary behaviors after residing in Korea and Chinese students residing in Korea showed poor nutrient-based diet quality. Conduct of a follow-up study using blood profile tests is needed in order to assess the nutritional status of Chinese students. These results would be used in planning of a nutritional surveillance program for Chinese students.
