ABSTRACT
Objective To verify the efficiency and stability of hydrogen-rich water preparation with hydrogen-rich rods. Methods ①Seven firenew hydrogen-rich rods were separately placed in seven plastic bottles, each filled with distilled water and soaked for 6 h, before the hydrogen concentration of the water was measured.This process was repeated 10 times.②After the hydrogen-rich rods with the strongest and weakest hydrogen product capacity were removed, the remaining 5 hydrogen-rich rods were placed separately into 5 plastic bottles filled with distilled water,put in a water bath pot at 20,40 and 60℃, respectively, and kept for 2, 4, 6, 8 and 10 h, respectively.Then, the hydrogen concentration, oxidation-reduction potential(ORP),and dissolved oxygen concentration(DO) were measured at various time points.③In order to determine the hydrogen emission rate from the hydrogen-rich water, the hydrogen-rich rods were constantly kept in some samples and the others were removed.All the sample bottle caps were kept open during the experimental process, and the hydrogen concentration was measured at such time points as 0, 10 and 30 min, 1, 2, 5, 12, 24, 30, 48 and 72 h, respectively.Results ①The hydrogen-rich rods used in this study could well meet the requirements.②When the environment temperature was kept constant, the hydrogen concentration of the water was increased with the soaking time of the hydrogen-rich rods, and the ORP of the water was reduced.However, the DO of the water was decreased with the rise of the environment temperature.③When the hydrogen-rich water was kept in opened plastic bottles with a 25 mm oral diameter, the hydrogen concentration of the samples with the hydrogen-rich rods reserved was almost about 0.50 ppm until 72 h, and that of the others was reduced to almost 0 ppm.Conclusion Our results demonstrate that the hydrogen-rich rods test is a simple and effective method for preparing hydrogen-rich water, which will be an valuable and useful method for using hydrogen-rich water in health promotion and prevention of chronic diseases.
ABSTRACT
Objective To evaluate whether flexible ambrosia,by which people can take special prebiotics instead of dining to alleviate their sense of hunger is a healthy, safe and effective weight loss method by analyzing the effects of flexible ambrosia on body weight, body composition, physiological and chemical indexes of young volunteers.Methods Young volunteers were tested on flexible ambrosia for seven days using special prebiotics instead of normal food.Body weight, waist circumference, body composition and blood biochemical indexes ( blood pressure, blood glucose, liver function, renal function, blood electrolyte, and blood lipid ) were measured and recorded before and after the test respectively.The volunteers′subjective feelings ( hunger, energy, fatigue, etc) were recorded during the test every day by way of e-form records.Results All volunteers of the flexible ambrosia test reduced their body weight, body mass index (BMI), waist circumference, visceral fat index (VAI) and body fat rate (Fat,%)significantly (P<0.01)in seven days, while the body water rate, muscle mass, body protein and bone did not significantly change or rise.There was no significant functional abnormity of the liver kidney, or blood electrolytes and blood lipid.All volunteers were in good physical condition, high-spirited and slept well, high quality sleep, without any obvious hunger and fatigue response in seven days.Conclusion Flexible ambrosia seems to be a healthy, safe and effective method, and provides an important scientific basis and reference for weight loss in the military.
