  • BACKGROUND/OBJECTIVES: Timing of almond intake during a day may result differently in the perspectives of body composition and changes of lipid profile. The current study was conducted to compare the effects of daily almond intake as a preload versus as a snack on body composition, blood lipid profile, and oxidative and inflammation indicators among young Korean adults aged 20-39 years old. SUBJECTS/METHODS: Participants were randomly assigned to one of three groups: a pre-meal almond group (PM), a snack almond group (SN) in which participants were instructed to consume 56 g of almonds either as a preload before meals or as a snack between meals, respectively, and a control group (CL) in which participants were provided high-carbohydrate iso-caloric control food. Measurements were performed at baseline, weeks 8 and 16. RESULTS: A total of 169 (M 77 / F 92) out of the 227 participants completed the study between June 2014 and June 2015 (n = 58 for PM; 55 for SN; and 56 for CL). A significant decrease in body fat mass was observed in the PM group at both weeks 8 and 16 compared with the CL. There were significant intervention effects on changes of body fat mass (P = 0.025), body fat percentages (P = 0.019), and visceral fat levels (P < 0.001). Consuming almonds as a daily snack reduced the levels of total cholesterol (P = 0.043) and low-density lipoprotein (LDL) cholesterol (P = 0.011) without changing high-density lipoprotein (HDL) cholesterol compared with the CL. CONCLUSION: Almond consumption as a preload modified body fat percentages, whereas snacking on almonds between meals improved blood lipid profiles. This trial was registered at ClinicalTrials.gov as NCT03014531.

  • This study examined the antioxidant activity and lipid composition of rats fed a high fat-high cholesterol diet containing Salvia plebeia water extract. Three levels (50 mg/kg, 200 mg/kg, 500 mg/kg) of Salvia plebeia water extract were administered to seven weeks old male Sprague Dawley rats for four weeks. The activity of glutathione peroxidase in serum was high in all groups that received the Salvia plebeia water extract (p<0.05). The glutathione reductase activity was high (p<0.05) in groups that received 50 mg/kg and 500 mg/kg of Salvia plebeia water extract. When rats received Salvia plebeia water extract, the content of MDA (malondialdehyde) in the serum and liver was low in all groups. In addition, the serum total lipid, triglyceride, total cholesterol and LDL-cholesterol contents decreased significantly (p<0.05). Total cholesterol and triglyceride levels in the liver were significantly lower in the group that received the Salvia plebeia water extract than in the control group (p<0.05). Salvia plebeia water extract improves lipid metabolism and it almost meets with the increase of antioxidant activity and peroxide formation reduction. Based on these results, supplemented of a high fat-hypercholesterol diet with Salvia plebeia can increase antioxidant activity and depress peroxide formation in serum, as well as liver cholesterol and triglycerides.

  • Carcass analysis of most economical parts of broilers were studied after they were fed with different protein levels of 16, 18, 20 and 23% for the starter period and 16, 18 and 20% for the grower period. The energy value of the feed was constant at 3,200 kcal ME/kg. The results for the starter and grower broilers showed similar pattern of responses. There were significant increased in weight gain, feed intake, protein intake, while there were significant decrease in the feed conversion ratio (FCR), abdominal fat and carcass fat when dietary protein increased. For the economical parts of the carcass, most of the fats were found in the thigh meat, while the lowest was found in the breast meat. The protein levels did not influence the meat production of the breast, drumstick and thigh portion. Increasing the protein intake, increased the broiler performance in relation to increased protein content of the breast, drumstick and thigh meat. The different fat contents of the meat might be due to differences in the rate of lipogenesis and fat deposition of the meat.

  • A unique biophysical membrane which surrounds the milk fat globules is called the milk fat globule membrane (MFGM). Various researches were studied about origin, composition, structure and bioactive components of MFGM. Bioactive protein components of MFGM play an important beneficiary function such as defense mechanism in new born. Among the bioactive lipid components from MFGM phospholipids showed health enhancing functions. The phospholipids also help in the production of certain dairy product from deterioration. MFGM phospholipids also showed antioxidant activity in some dairy products such as butter and ghee produced from milk of buffalo. Based on the beneficial effects, researchers developed MFGM as functional ingredients in various food products. This current review focuses on health enhancing function of MFGM and its components in various dairy products.

  • The purpose of this study was to investigate the relationship between bone mineral density(BMD), body composition and life styles of female college students. The subjects were 334 students with a mean age of 21.0 years. BMDs of forearm and calcaneus were measured by dual energy X-ray absorptiometry, and body composition was measured by bioelectrical impedence analysis. The means for weight, height, and body mass index(BMI) of the subjects were 55.7 kg, 161.0 cm, 21.5 kg/$m^2$, respectively. Grouping by the BMI, 13.2% of the subjects were classified as overweight, and 11.1% of the subjects as obese group. BMD in the forearm and calcaneus were 0.390 g/$cm^2$, 0.514 g/$cm^2$. In the forearm, 58.1% and 9.6% of the subjects were classified as osteopenia and osteoporosis, respectively, and in the calcaneus, 12.0% and 0.3% of the subjects were classified as osteopenia and osteoporosis, respectively. Body weight, skeletal muscle mass, lean body mass, fat mass and BMI were positively correlated with BMDs in the forearm and calcaneus($r$=0.180~0.495, $p$ <0.01~0.001), and height, % body fat and waist-hip ratio(WHR) were positively correlated with BMDs in the calcaneus($r$=0.213~0.239, $p$ <0.001), but not in the forearm. The factors such as beginning age of cigarette smoking and alcohol drinking and exercise had significant influence on BMD($p$ <0.05; p<0.001), whereas sleeping hours, activity level, frequency of exercise, meal times, frequency of snack and fried food intake, breakfast skipping and amount of meal had not significant influence on BMD. Therefore, the acquisition of balanced body composition is necessary through the increase of fat free mass and muscle mass, not through the increase of fat mass among female college students.

  • Purpose: The purpose of this study was to examine the effect of a 12-week combined exercise training program on the body composition, physical fitness levels, and metabolic syndrome profiles of obese women. Methods: Twelve obese women were assigned to the combined exercise training program group. The women underwent training for 70-90 min/d, three times per week for a period of 12 weeks. Paired samples t-tests were performed using SPSS ver. 17.0 for analysis of the results. Results: The results of this study showed that body-composition parameters such as weight, fat-free mass, body fat mass, body-mass index, body fat, waist-hip ratio, basal metabolic rate, and intra-abdominal fat, physical fitness parameters such as muscle strength, muscle endurance, flexibility, and cardiac endurance, and metabolic syndrome biomarkers such as triglyceride levels, high-density lipoprotein cholesterol levels, glucose levels, systolic blood pressure, and waist circumference before participation the training program differed significantly from those after participation in the training program (p<0.05). However, diastolic blood pressure before participation in the training program did not differ significantly from that after participation in the training program (p>0.05). Conclusion: We concluded that a 12-week combined exercise training program could be a good exercise program for improvement of the body composition, physical fitness levels, and metabolic syndrome profiles of obese women.

  • The purpose of this study is to reveal the effect of electrical stimulation of body composition in obese person. Subjects were 30s to 40s aged healthy workers(2004. 3. 8~4. 17) in the S general Hospital in Suwon and they were brought to manage obesity. Subjects were divided into control group(Female<0.85, Male<0.90) and study group(Female>0.85, Male>0.90) by WHR(waist-hip ratio) that is measured by Automatic body composition analyzer(InBody 3.0). And we divided the study group with randomized methods into group A(n=8) and group B(n=8). Then we compared and analyzed the change of muscle mass, body fat, abdominal girth, WHR, BMI(body mass index) after application of electrical stimulation, three times a week, for 30 minutes in each session with 50 Hz of pulse frequency, $20\;{\mu}s$ or $250\;{\mu}s$ of pulse duration. There was statistically meaningful decrement of body fat(p<0.05) and abdominal girth(p<0.05) but not of body weight, muscle mass, WHR and BMI in the control group after application of electrical stimulation with 50 Hz, $20\;{\mu}s$. There were meaningful change of abdominal girth(p<0.05), WHR(p<0.05) and BMI(p<0.05), but not of body weight, muscle mass and body fat after application of electrical stimulation with 50 Hz, $20\;{\mu}s$ in group A. We applied electrical stimulation with 50 Hz, $250\;{\mu}s$ in group B, then there were meaningful change of body weight(p<0.05), body fat(p<0.01), abdominal girth(p<0.01), WHR(p<0.05) and BMI(p<0.01) but not of muscle mass only. Consequently, the pulse duration is the main parameter of electrical stimulation that affect the body composition of obese person in this study and if we combined the diet control to reduce blood components we could have better result. So it would be more effective to manage localized obesity(in abdomen, thigh, upper arm, etc.) if you apply electrical stimulation considering the pulse duration.
