Drinking emulsified medlar is beneficial to enhance the immunity of the elderly

A new study shows that the elderly people who drink emulsified Lycium barbarum for a long time will increase their resistance to specific infectious diseases Nestle's scientists in Switzerland and China are studying whether their immune response to seasonal influenza vaccines can be enhanced by daily supplementation of "emulsified Lycium barbarum" to healthy Chinese aged 65 to 70 The research project, published in the Journal of anti-aging research, is considered to be the largest randomized clinical trial to test the immunity of Lycium barbarum to the elderly Previously, Nestle scientists also published research results on emulsifying Lycium barbarum, a patented product of Nestle Company, which is made of milk protein extracted Lycium barbarum A study conducted in collaboration with Hong Kong University of technology found that emulsified Lycium barbarum could make the natural antioxidants in Lycium barbarum more easily digested and absorbed by the body after ingestion Half of the 150 people who took part in the latest study drank hot soup containing emulsified Chinese wolfberry every day for three months, while the other half of the control group drank placebo On day 30 of the study, all participants were vaccinated against seasonal influenza Before and after vaccination, scientists measured the level of influenza antibodies in each participant's body The results showed that although the level of influenza antibody in all participants increased after vaccination, the number of people who took emulsion Lycium increased more than those who did not "People's natural resistance to infections and antibody production will decline with age," said Dr Karin Vida, a scientist at the Nestle Research Center in Switzerland who led the study "Measuring a person's ability to produce antibodies after vaccination is an effective way to measure their 'immune status'." "The results of this study, together with the data from previous studies, show that the immune system can be enhanced by emulsifying Lycium barbarum." "We believe that emulsifying Lycium barbarum can improve immunity, such as reducing the incidence of respiratory tract infection," she added "This is particularly important for people with reduced immunity, such as the elderly." In recent years, Lycium barbarum has attracted more and more attention in Europe and North America because of its potential health effects and anti-aging function However, there is little scientific evidence to support its effect Wang junkuan, director of Nestle's Beijing R & D center, said: "the good effect of wolfberry on eyesight is well known in Chinese food culture." "Nestle has done research to prove that Lycium barbarum is good for eyesight, but we believe that this is the first modern study to show that Lycium barbarum combined with milk can help enhance immunity."
