Dietary supplements derived from natural sources are an essential factor in optimizing athletic performance. It has been proposed that the extract of Momordica charantia (M. charantia) that is known as a bitter melon can be potentially used as a novel supplement for health promotion. This pilot study aimed to examine the effects of the M. charantia extract when administered in the form of a sports drink, and we evaluated changes in body composition and metabolic factors in tennis players after 4-week consumption of the extract. Eight male college tennis players were instructed to consume an M. charantia extract 6 times per day (3 in the morning and 3 in the afternoon, and the total daily intake was 600 ml). Collected data were analyzed using paired t-tests to examine the changes over time after consumption of the M. charantia extract. The results revealed a significant increase in the trunk muscle mass, basal metabolic rate, and daily calorie intake (p < 0.05). Levels of protein, minerals, and total body water showed an increased tendency (not statistically significant), whereas intracellular water and extracellular water showed a decreased trend. Furthermore, fat-free mass, skeletal muscle mass, and muscle mass showed an increased tendency. In conclusion, consumption of the M. charantia extract caused an increase in parameters related to protein, muscle mass, and metabolism. It seems that follow-up studies related to fatigue, inflammation, and stress hormones related to the M. charantia extract consumption would be needed.

A total of 800 one-day-old chickens (Cobb 500) were obtained from a local hatchery and allocated randomly to five dietary treatments. This study conducted for 42 d. Treatment groups included 1) CON (control), 2) T0.3 (0.3% of thyme extract), 3) T0.6 (0.6% of thyme extract), 4) G0.3 (0.3% of garlic extract) and 5) G0.6 (0.6% of garlic extract). Thyme extract included $90{\mu}g/ml$ Carvacrol and 400 mg/ml thymol while garlic extract included 100 mg/ml elastin. There were no significant effects among the treatments on weight gain, feed intake and feed conversion ratio over the entire trial. Also, no significant differences were observed between CON group and other treatments in plasma parameters (cholesterol, triglyceride and HDL) and hematocrit. Sex of chickens had no effect on blood parameters. Supplementation of herb extracts did not affect carcass characteristics including carcass yield, breast, thigh and abdominal fat. There were no significant differences observed in carcass characteristics between males and females fed with different levels of herb extracts. In conclusion, supplementation of garlic and thyme extracts as feed additives at two levels of 3 and 6% in the present study did not improve performance and carcass traits of broiler chicks.

The large-scale preparation method for black soybean peptide (BSP; about 70% less than 10,000 Da; highly enriched with glutamic acid, aspartic acid, and arginine) was developed, and its effect on weight reduction and lipid profiles in rats was investigated. Sprague-Dawleymale rats were assigned to four dietary groups (high-fat diets containing 0, 2, 6, and 10% BSP) and fed four weeks to examine the effects of BSP. During the experiment, food intake was measured every two days and body weight was monitored two times a week. After the supplementation of BSP, liver and adipose tissues (epididymal, retroperitoneal and perirenal adipose tissue) in the rats were weighted and the lipid profiles in serum, liver, and feces were analyzed. At the results of body weight gain, liver and epididymal adipose tissue weight, BSP groups were more decreased than HF group (0% BSP), with greater decreases at higher BSP levels. The same patterns were shown in lipid profiles of serum, as BSP was increased, triglyceride and total cholesterol concentration decreased. The serum HDL-cholesterol level was increased with increasing at BSP levels. Total cholesterol concentration of liver and feces were decreased and increased, respectively, as BSP increased. The results confirm that BSP is involved in reducing the body weight and the improvement of lipid composition in serum and liver of rats and that BSP can be applied in weight reduction in the food products industry.

The present study was conducted to evaluate the usefulness of four kinds of legumes(black soybean: BS, yellow soybean: YS, green peas: GP, soybean curd residue: SCR) as a high-fiber supplement in the therapeutic diet for diabetic patients. Seven groups of normal and streptozotocin-induced diabetic rats were fed isocaloric experimental diets containing 8% dietary fiber from one of legumes for 6 weeks. The effects of legumes on the gastrointestinal function and diabetic symptoms in diabetic rats were also examined and compared with the effects of cellulose or pectin diet. Legume supplementations had no significant effects on alleviating typical diabetic symptoms such as polydipsia, polyphasia, polyuria, and urinary glucose excretion when compared with cellulose or pectin supplementations. The supplementations of legumes all resulted in remarkable changes in gastrointestinal functions: shortening of GI transit time and increases in fecal volume, fecal water and crude fat contents. Legume supplementations appeared to supress the damages of the small intestine villi and the enteritis symptoms in diabetic rats. GP led to regular villus patterns closer to normal villus. BS, YS and GP led to the enlargement of cecum in diabetic rats. In conclusion, the present studies have demonstrated that legumes may possess a significant physiological actions in the control of various diabetic conditions.

Thirty mael Sprague Dawley rats of 3 weeks of age were adopted to investigate changes in nutritive quality of the traditional, fermented soybean foods, Meju and Chungkugjang prepared by culturing with Aspergillus oryzae and the rice straw, respectively. The levels of each dietary protein were set at 10% . The effect of supplementation of fermented soybean on the rat diet was evaluated by measuring growth rate, feed efficiency. weight of the pancreas and biological values, such as NPU, PER and NPR on day 10. After incubation of soybean with Aspergilllus oryzae and the rice straw, the contents of crude protein, crude fat and crude ash were increased, but the levels of crude fiber and nitrogen-free extract were reduced. The amounts of feed intake, body weight gain an feed efficiency were greater for the rats fed dietscontaining heated unfermented soybeans or Meju compared to rats fed the diet containing raw soybeans. Pancreating enlargement was observed in the rats fed diets containing raw soybeans. The values of NPR and PER in rats fed diets containing Meju and Chungkugjang were significantly higher than those of rats fed diets containing raw soybeans. The values of NPU in rats fed diets containing raw soybans, heated unfermeted soybeans. Meju and Chungkugjang were 39.40%, 40.60%, 45.00% and 46.205, respectively, demonstrating no significant differences.

We evaluated the effect of soybean dongchunghacho [SD, cultivated dongchunghacho fungus (Paecilomyces tenuipes) on soybeans] on dimethylhydrazine (DMH)-induced DNA damage and oxidative stress in male F344 rats. The animals were divided into 3 groups and fed a casein-based high-fat, low fiber diet without (DMH group) or with 13%(w/w) of soybean (DMH+S group), or SD (DMH+SD group). One week after beginning the diets, rats were treated weekly with DMH (30 mg/kg, s.c.) for 6 weeks; dietary treatments were continued for the entire experiment and endpoints measured at 9 weeks after the first DMH injection. SD supplementation reduced DMH-induced DNA damage in colon cells and reduced plasma lipid peroxidation. Thus, SD may have therapeutic potential for early-stage colon carcinogenesis.
