Eating mushrooms helps reduce the risk of mild cognitive impairment

With the rapid aging of the population, the number of elderly people with dementia is expected to increase rapidly in the next 10 to 20 years.It will be a great challenge for the elderly to keep their brain healthy and cognitive function good.Professor Feng Lei of the National University of Singapore said, "mushroom intake can help reduce the risk of mild cognitive impairment."

Professor Feng Lei, National University of Singapore

According to its introduction, the cognitive protection function of mushrooms may be related to an ingredient called ergothione.Studies have shown that ergothione has antioxidant and anti-inflammatory effects and protects nerve cells, which is why older people who eat more mushrooms are less likely to suffer from mild cognitive impairment.

Breakthrough in the cultivation of Lentinus edodes and Morchella

"there is much room for improvement in per unit yield and quality of Lentinus edodes in China. The sustainable development of the industry is faced with eight scientific and technological problems: sawdust substitution of cultivation raw materials, strain degradation, efficient color conversion of bacteria bags, breeding of excellent varieties, water conservation and water supply of bacteria bags, regulation and control of cultivation environment, improvement of product flavor and rapid identification of strain quality."

At the meeting, Professor Bian Yinbing of Huazhong Agricultural University put forward a systematic solution to the eight scientific and technological problems and research strategies of Lentinus edodes industry.

Since the world's first approved new variety of Morchella "Sichuan Morchella No. 1" was bred in 2013, researcher Gan Bingcheng and his research group have successively bred 5 new varieties of Sichuan Morchella, which have been authorized for the protection of new plant varieties.

Through the research, innovation and application of matching strain propagation and efficient cultivation techniques, the research group successfully realized the commercial cultivation of Morchella in the field, leading and driving the rapid development of Morchella industry in the whole country.

The bad condition of spleen and stomach is related to intestinal flora.

The spleen is responsible for the transformation, absorption and transfer of dietary nutrients and water dampness (qi, blood and body fluid); the stomach is responsible for receiving and ripening the water valley (that is, the digestion process).

Professor Liu Fengbin, director of the first affiliated Hospital of Guangzhou University of traditional Chinese Medicine, introduced at the meeting that the coordination of spleen and stomach function is directly related to the function of the five internal organs of the human body.Therefore, the spleen and stomach plays an important role in the regulation of human nutrition, and the poor spleen and stomach is related to the intestinal flora of the human body.

Selenium-rich Cordyceps shows bone protection and anti-tumor activity.

Pharmacological and clinical studies have shown that polysaccharides are one of the main bioactive components of Cordyceps sinensis Cs4, and have a wide range of health promotion and therapeutic effects, such as immune regulation, anti-tumor, and bone protection.

Using cordyceps polysaccharide as a stabilizer, Huang Jiaxing, an associate professor of Hong Kong Polytechnic University, and his team successfully prepared a new type of highly stable Cordyceps polysaccharide functionalized nano-selenium (Cs4-SeNPs).

Huang Jiaxing introduced at the meeting that this new type of cordyceps polysaccharide nano-selenium (Cs4-SeNPs) showed significant bone protection in vivo in cell and animal models.

The birth of Cs4-SeNPs is expected to develop a new type of high-quality, safe and empirical bone protectin for patients with climacteric osteoporosis in China, and contribute to the strengthening of national bone health.

Selenium is an important trace element necessary for human body.

A large number of studies have shown that selenium has a wide range of biological functions, such as antioxidant, anti-tumor, anti-inflammatory, anti-hypertension, hypoglycemic and so on.Using edible and medicinal fungi as carriers for selenium-rich research and the development of selenium-rich products is the current research hotspot.Professor Chen Fengfeng of Jinan University and his team found that selenium-rich Cordyceps militaris showed good antioxidant activity, anti-tumor activity, and can reduce the damage of normal lung cells caused by radiotherapy.

In addition, based on the structural characteristics of fungal polysaccharides, the team functionalized nano-selenium to improve its physiological stability and targeting, and found that functional nano-selenium can be used as a tumor immune sensitizer with high efficiency and low toxicity. it can efficiently activate immune cells in tumor and its microenvironment and enhance the persistence of killing tumor.

Professor Chen Fengfeng said that combining it with low-dose radiotherapy can greatly improve the overall therapeutic effect of tumor and achieve multimodal tumor immunotherapy.

Intestinal flora is related to the occurrence of Alzheimer's disease.

The network regulation system of "intestinal microorganism-intestinal-brain axis" is an important part of the normal operation of the human body. "

Through experimental observation, Dr. Chen Diling, an associate researcher at Guangdong Institute of Microbiology, found that intestinal flora is related to the occurrence and development of AD (Alzheimer's disease).

Studies suggest that intestinal microorganisms and their metabolites participate in the occurrence and development of AD disease by affecting the host's functions such as oxidative stress, inflammation and autophagy.

In addition, the early intervention of dietary nutrition can be used as an important strategy for the prevention and delay of AD, a complex disease.

The establishment of foodborne strain database can strengthen food risk early warning.

(Listeria monocytogenes) is an important foodborne pathogen with strong adaptability. Infection can cause septicemia, meningitis and other diseases, and the fatality rate is as high as 20% to 30%.

Dr. Chen Moutong, Associate researcher of Guangdong Institute of Microbiology

Dr. Chen Mutong, associate researcher of Guangdong Institute of Microbiology, collected 4300 food samples from 43 cities or regions in China for risk identification of Listeria monocytogenes. The results showed that the overall contamination rate of Listeria monocytogenes was 16.5%.

Through the establishment of the resource database and risk identification database of Listeria monocytogenes in China, it can provide basic data for the rapid detection technology, hazard mechanism, risk early warning and prevention and control technology of Listeria monocytogenes in China.
