The purpose of this article is twofold: 1) to provide nutrition professionals with the history of how the concept of sustainable diets was introduced to the nutrition profession and 2) to describe how different sustainable agricultural practices offer potential for improving human nutrition and health. The idea of connecting sustainable agriculture With the promotion of human nutrition and health is not new. It is a concept that was introduced to the nutrition profession more than 20 years ago. To foster healthful, sustainable diets, consumers need to choose more whole foods. From the standpoint of nutrition and health, whole foods are naturally higher in fiber and lower in fat, sodium, sugar and additives compared to highly processed foods. From the standpoint of agricultural sustainability, whole foods bypass the high-energy costs of food processing and transportation. Organic farming systems offer potential benefits to human health through reducing farmers' exposure to pesticides and by increasing the total phenolic content in selected food crops. Participation in farmers' market nutrition programs and gardening has been associated with increased fruit and vegetable intake. Gardening may also be a way to increase access to fresh produce in low-income populations that do not have access to nutritious food outlets and to increase physical activity. Further research is needed to assess the human nutrition and health benefits of other types of sustainable agriculture strategies and to investigate the links among different agricultural practices with nutrient and total phenolic content in a wider variety of important food crops.

This study examined the effects of postoperative medical nutrition therapy on patients who had undergone bariatric surgery. Eighty seven patients who underwent bariatic-surgery at Yeouido St. Mary's Hospital from January 2007 to April 2009 were evaluated. The bariatric surgery patients included 42 Laparoscopic Roux-en Y gastric bypass (LRYGB) and 45 Laparoscopic adjustable gastric banding (LAGB) patients. Weight loss was more significant after LRYGB than after LAGB after 9 months (p<0.05). The LRYGB group was more satisfied with the weight loss (LRYGB 4.4/5.0, LAGB 3.0/5.0 p<0.001). The mean albumin, hemoglobin and hematocrit levels were significantly lower in the LRYGB group than in the LAGB group at the time of discharge (p<0.05~0.001). The GOT/GPT was significantly higher in the LRYGB group at the time of the operation than the LAGB group (p<0.01). The LRYGB group showed significantly lower intakes of total energy, carbohydrates, protein and fat from 1 week after surgery than the LAGB group. Multiple regression showed that the weight change after LRYGB was significantly more associated with the intakes of total energy at 1 week after surgery (p<0.01), SWS (sweets and high-calorie beverages) at 1 and 6 months after surgery (p<0.001), and fat at 3 months after surgery (p<0.01). In addition, LAGB was significantly more associated with the intakes of protein and NLS (non-liquid sweets) at 1 week after surgery (p<0.001, p<0.01), carbohydrate at 1 months after surgery (p<0.01), total energy at 3 months after surgery (p<0.001), HCL (high-calorie liquids) at 6 months after surgery (p<0.05), and fat at 9 months after surgery (p<0.01). These results suggest that continuous-follow-up medical nutrition therapy is needed according to the types of bariatric surgery, particularly during the weight loss phase (the first 1 week to 12 months).

This study was undertaken to investigate the effects of ruminally protected amino acids (Methionine and Lysine) on in vitro ruminal parameters, and in vivo milk yield and milk composition in mid-lactating cows. In the first in vitro experiment, there were no statistical significances between treatments in ruminal pH and dry matter digestibility during various incubation times. In the second in vivo experiment, milk yield decreased by 11.92% in control and 5.68% in the treatment respectively, but decrease rate of milk yield in the treatment was lower than control. Milk yields naturally decreased as time goes by since the DIMs(Days in milk) of the cows in experiment were in mid-lactation period. 4% FCM(Fat corrected milk) and milk protein yields also, respectively, decreased by 11.25% and 11.09% in control and 6.16% and 5.47% in the treatment as compared with the intial. Milk protein and milk fat production were higher in the treatment(0.90kg, 1.10kg) than those of control(0.66kg, 0.79kg). Milk fat content significantly increased with supplementing protected amino acids as compared to control(P<0.05). From the above results, protected amino acids were positively utilized in the performances of mid-lactating cows without inhibiting rumen fermentation. Further investigation is suggested for essential amino acid composition and intestinal digestion rate out of rumen bypass protein in dietary protein to be estimated.
