The nutritional value of raspberry

Raspberry? Maybe a lot of people look at this strange noun with some big heads What is raspberry? Raspberry, also known as raspberry, tray and raspberry, is a small perennial deciduous shrub of Rubus genus in Rosaceae There are more than 750 kinds of raspberry Because its fruit type, color and taste are similar to strawberries but grow on trees, it is named raspberry This fruit contains a lot of anti-aging substances such as vitamin C, e, superoxide dismutase, Y-aminobutyric acid, and anti-cancer substances such as tannic acid, among which vitamin E and tannic acid are the most In the United States, red raspberry is regarded as a cancer killer, and people praise it as "Ruby" Experts tried to mix tannic acid in raspberry with liver cancer cells and found that the former can significantly inhibit the growth of the latter Later, experts have been focusing on the medicinal value of natural plants, and have found that grapes and apples have the effect of preventing the proliferation of cancer cells In recent years, with the support of the National Natural Science Foundation of China, the fund for returned overseas students from the Ministry of personnel, and the fund for scientific and technological research in Heilongjiang Province, the expert group has carried out the research on the mechanism of raspberry prevention and inhibition of liver cancer from the perspectives of Medicine, nutrition, botany, cytology and molecular biology It is well known that oxidative damage of genetic material is one of the causes of most tumors The results showed that with the increase of the concentration of phytochemicals in raspberry, the ability of antioxidant damage was enhanced The inhibition rate of raspberry extracts of different concentrations on HepG-2 cell line was gradually increasing, and the highest inhibition rate was about 90% With the increase of the concentration of raspberry extract, the size of the tumor on the liver of the experimental group decreased, the number of tumor decreased, the rate of tumor formation decreased, and the degree of nodule decreased At the same time, proteomic studies show that there are two protein spots that are very likely to be the protein targets of raspberry in the prevention of liver cancer Expert evaluation pointed out that at present, there are two synergistic risk factors that greatly increase the risk of liver cancer, one is chronic hepatitis B virus infection, the other is chronic exposure of aflatoxin, a highly toxic liver toxin produced by molds that pollute the staple food One of the important ways to reduce the influence of these two carcinogenic factors is chemical prevention, that is, taking drugs or food supplements to counteract the harm of aflatoxin In the future, using the plant chemical components extracted from raspberry, making reasonable collocation and composition of preventive agent are very helpful to prevent the occurrence of liver cancer, inhibit the development of liver cancer, and improve the survival rate of patients with this disease How to reasonably eat raspberry and other fruits? Experts suggest: first, eat at least two kinds of fruits such as raspberry, grape, apple or orange every day If you eat with more than three kinds of vegetables such as cauliflower, tomato and carrot, the effect will be better; second, soak and wash raspberry, grape, apple and other fruits, and it's better to eat them as a whole without peeling; Third, the daily intake of raspberry should not be less than 200g for high-risk groups such as liver cancer It is better to eat raspberry between meals, if it is eaten with other two fruits and two vegetables at the same time.
