Black beans can reduce the age of blood vessels

Black beans, also known as Lu beans, black beans, Jidou, Zhizai beans, horse bean, etc It can be divided into green kernel black beans, yellow kernel black beans and Hengchun black beans In recent years, consumers have learned from various information channels that black beans have high nutritional value and are very beneficial to human body Therefore, people who pay attention to healthy life began to add black beans into their daily recipes: in the morning, they beat up a cup of black bean milk, hand out a plate of black bean sprouts, and cook and pot soup with black beans In short, the figure of black beans has been active on the table of ordinary people However, what benefits does black bean have to human body? I think we all just know why This article will elaborate the health effect of black beans on human blood vessels, so that we can understand the benefits of black beans Fujicco Co., Ltd of Japan cooperates with Professor Ludian Jun of Agricultural Science Research Department of Graduate School of Kobe University to carry out the research on black soybeans The research results were announced at the 2017 annual conference of Japan agrochemical Society held in Kyoto, Japan, from March 17 to 20, 2017 The company has always focused on the polyphenols contained in the seed coat of black beans, and has carried out various functional studies, especially on the efficacy of blood vessels and blood flow The research confirmed that black bean polyphenols can improve the function of blood vessel cells, improve the cold symptoms and swelling problems It is known that black soybean polyphenol is a blood vessel aging There is a correlation between vascular endothelial function (vascular health) and age At present, it is known that with the increase of age, the vascular function will decline and then the blood vessels will harden The results measured by the accelerometers also show that the "age of blood vessels" is often higher than the actual age, and even has a great difference In addition to the increase of age, oxidative stress is also a major reason for the decrease of endothelial function Vascular endothelial cells contain nitric oxide (no), which can promote the expansion of blood vessels, and then produce a variety of bioactive substances However, due to the influence of oxidative stress, their production capacity becomes poor In this study, the following experiments were carried out on vascular endothelial function Several previous studies have confirmed that the effects of black soybean on vascular health include the following: ① black soybean seed skin extract was used as the experimental meal for 24 healthy people for 2 weeks The results showed that the extract from the seed coat of black bean could reduce the age of blood vessels by about 3 years on average and increase the amount of no which could promote the expansion of blood vessels ② The black bean processing products were used as experimental meals 44 healthy women were tested for 8 weeks The results showed that the intake of seed coat extract of "fried black bean" could reduce the age of blood vessels by about 2 years, and the urinary 8-OHdG value, as an indicator of oxidative stress, also decreased ③ Using the black soybean in the form of processing, the seed coat of boiled or dry fried black soybean was put into the animal to compare its function The results showed that, from the aspect of blood cholesterol inhibition, fried black soybean seed coat showed high functionality, and showed excellent characteristics under the processing method of better retention of polyphenols Based on the above studies, it can be concluded that black soybean polyphenol has the function of maintaining blood vessel health Black soybean seed coat extract improves vascular function in order to investigate whether black soybean seed coat extract can improve vascular endothelial function, intake test was conducted in healthy men and women The results showed that the arterial elasticity and vascular age of the subjects who took black soybean seed skin extract were improved In addition, the amount of NO metabolites excreted from urine also increased, which is expected to improve the no production capacity of vascular endothelial cells In this study, 24 healthy men and women over the actual age of blood vessel were taken 100 mg black soybean seed coat extract or placebo (dextrin) daily for 2 weeks, and then the age of blood vessel and the amount of NO metabolites in urine were measured In order to investigate the effect of "dry fried black beans" on improving the function of vascular endothelium in human experiment, and the effectiveness of black soybean seed skin extract on vascular health care, the researchers conducted a human experiment with black soybean processing products as experimental diet Healthy women were given "dry fried black beans" for 8 weeks to confirm that their vascular elasticity and arterial age were improved, while oxidative stress was reduced In this study, 44 healthy women whose age of blood vessel was higher than the actual age were taken as subjects, who were given 30 g / day of "dry fried black beans" for 8 weeks, and then the age of blood vessel and 8-hydroxydeoxyguanosine in urine were measured The results showed that the age of blood vessels decreased and the 8-hydroxydeoxyguanosine, a marker of oxidative stress, also decreased Processing black soybean can improve the polyphenol content In fact, when people eat black soybean, they usually go through a certain cooking process, so it is assumed that black soybean will have component loss or structural change Therefore, in order to investigate the polyphenol content and the functionality of black soybean processing products, the researchers prepared the cooked black beans and baked black beans in advance, and fed their seed coats to the animals respectively At the same time, the unprocessed yellow soybean seed coat and black soybean seed coat were used as the control group The results showed that the boiled and roasted black soybeans contained more polyphenols, so they were considered to have higher functions, such as lowering cholesterol The specific method is to extract polyphenols from each experimental food with 70% acetone containing 0.5% acetic acid, and then use HPLC to measure the content of polyphenols ICR mice were fed with 2% powder samples for one week The concentrations of cholesterol in blood and polyphenols in plasma were measured The results showed that the roasted black soybean contained more polyphenols In addition, in the intake test, the effect of cholesterol concentration inhibition in blood was the strongest in fried black beans Extended reading vascular age is an indicator of vascular aging When blood is delivered from the heart, it changes the shape of blood vessels, which can be captured by an accelerometer at the fingertips Because the changing state is related to endothelial function (i.e aging), the acceleration pulse aging index can be calculated.
