15% of couples of childbearing age in the world Although in most cases, the cause of infertility is attributed to male or female factors, almost 20% of the population is in idiopathic infertility In particular, the evaluation and classification of male infertility depends on the analysis of its semen, which includes three parameters, i.e sperm concentration, morphology and motility These parameters have certain limitations in predicting sperm fertility In addition, more and more data show that life style may affect men's fertility by changing the endocrine characteristics, spermatogenesis and sperm function of the body Therefore, it is very important to identify multiple factors that induce infertility for the development of simple and effective therapies to treat the fertility problems of the current childbearing age population 【2】 ELife: why does fat diet damage the communication between the intestine and the body doi: 10.7554/elife.48479 according to a new study conducted by Duke University, high fat diet can interfere with the communication between the intestine and the rest of the body A research team from Duke University found that zebrafish can communicate with brain and other body parts after eating, so that the latter can understand their diet However, high-fat food can completely cut off this communication The key cell that mediates this communication is the intestinal endocrine cells, which are distributed in a small amount in the whole intestinal wall, but play a key role in signaling the digestive tract In addition to releasing hormones, these cells have direct connections with the nervous system and the brain These cells produce at least 15 different hormones to send signals about gut movement, satiety, digestion, nutrient absorption, insulin sensitivity and energy storage to other parts of the body Because the gut endocrine cells are the key factors of digestion, satiety and subsequent eating behavior, the destruction of this mechanism may be to some extent that people who eat high-fat diet will inadvertently overeat 【3】 J Neurosci: take a ketone diet or hope to help the body resist Alzheimer's disease doi: 10.1523/juniursci.1446-19.2019, a report published in the International Journal of neuroscience is entitled "SIRT3 haploinsufficiency groups loss of GABAergic interneurons and neural network hyperactivity in an Alzheimer's disease" In the model study, researchers from institutes such as the National Institutes of health found that a diet supplemented with ketones could protect brain neurons from death during the progression of Alzheimer's disease When in the early stage of Alzheimer's disease, the brain usually becomes over excited, which may be achieved by the loss of inhibitory or GABAergic interneurons, which can prevent other neurons from sending out too many signals Compared with other neurons, intermediate neurons often need more energy When they encounter Alzheimer's disease protein - β - amyloid protein, these intermediate neurons will become very easy to die β - amyloid protein will damage the cell's energy factory - mitochondria by interfering with the function of SIRT3 protein SIRT3 protein can protect the function of mitochondria and protect neurons from damage Damage 【4】 SCI immune: ketogenic diet can help fight against influenza doi: 10.1126/sciimmune.aav2026 recently, ketogenic diet (high fat, low-carbon water diet) is very popular in the general public, but at the same time, it makes the existence of influenza virus "intimidate" A new study published by Yale University in the journal Science immunology shows that mice fed a ketogenic diet are more resistant to influenza than those fed a carbohydrate rich diet Ketogenic diets - including meat, fish, poultry and non starch vegetables - activate T-cell subsets in the lungs, thereby increasing the production of mucus in respiratory cells, a mechanism that researchers report can effectively capture viruses The authors found that immune system activators, known as inflammatory bodies, can cause harmful immune system responses in their hosts This study shows that ketogenic diet can prevent the formation of inflammatory bodies The authors want to know if diet affects the immune system's response to pathogens such as influenza viruses 【5】 J physical: father's low protein diet may affect future generations' cardiovascular health doi: 10.1113/jp278270 recently, an International Journal of the Journal of In the Research Report on physiology, scientists from the University of Nottingham found that the father's lack of protein in diet may affect the quality of his sperm, thus affecting the long-term cardiovascular system health of offspring In the article, the researchers said that feeding low-quality low protein food to male mice may damage the vascular function of their offspring, which is an important indicator of the occurrence of heart disease At present, there is research evidence that the current diet and health status during pregnancy will affect the development of offspring, often leading to cardiovascular abnormalities and metabolic diseases in later generations However, there are few studies on how father's diet affects the cardiovascular health of offspring Photo source: shutterstock / GTS [6] nature: listen to the doctor and eat less salt! In a new study on mice, researchers from Weill Cornell Medical College in the United States found that high salt diet may lead to the lack of nitric oxide, which may have a negative impact on cognitive function When the level of nitric oxide is too low, tau protein in brain phosphorylates, which leads to dementia The results were published in the journal Nature In the new study, the researchers tried to understand a series of relationships between salt intake and poor cognitive function, and concluded that reducing salt intake and maintaining healthy blood vessels in the brain might "avoid" dementia Protein tau deposits are related to the production of human Alzheimer's disease The researchers said that our study proposed a new mechanism of salt mediated cognitive impairment, and provided further evidence that there was a correlation between eating habits and cognitive function 【7】 Is the popular "hormone diet" really effective? News reading: Horse feet are all the range, but do they actually work? When it comes to weight loss and health, diet never seems to be in short supply, and some fitness enthusiasts claim to have relaxed and sustainable weight loss Some of the most popular diets include a ketogenic diet (low carbohydrate, high-fat diet), a carnivore diet (only meat and other animal products), and an intermittent fast (only within a strict time frame or on certain days) But another diet that people have been focusing on recently is hormonal diet, which claims that people are trying to lose weight The reason is that the hormones in the body can not function normally There are many books on this topic And the advocates of hormone diet think that people can control or "reset" the hormones in their bodies through diet and exercise, so as to reduce their body weight rapidly and significantly There are many changes in diet, but the main purpose is to lose weight The key is to correct the imbalance of hormones in the body Hormones play a key role in the daily metabolism of the body, including digestion of food to help bone growth, which can be transported to the whole body through the blood and play the role of chemical messengers to guide cells to complete many tasks For example, insulin can help regulate the metabolic process of the body, which can make the body store carbohydrates from food as energy in muscle cells When we eat, it will promote the rise of blood sugar level, so as to promote the release of insulin from the pancreas to the blood Later, insulin will be adsorbed on the cells and send signals to make it absorb sugar from the blood and store it For later use 【8】 Cell metal: how does a high-fat, high carbohydrate diet affect brain health? Doi: 10.1016/j.cmet.2019.08.010 many studies will clarify the molecular mechanism of obesity induced by unhealthy diet, but it does not deeply analyze how diet causes neurogenic changes in individual brain? Recently, in a research report published in the international journal cell metabolism, scientists from Yale University found that high-fat diet may induce dysfunction of the brain hypothalamus region, which can regulate the body's weight balance and metabolism In this paper, the researchers evaluated the molecular mechanism of hypothalamic inflammation stimulated by high-fat diet (especially the diet with high content of fat and carbohydrate) Hypothalamic inflammation is a physiological reaction in obese and malnourished individuals The researchers pointed out that the occurrence of hypothalamic inflammation occurs three days after an individual ingests high-fat food, or even in his or her body They are very interested in the fact that these changes happen so fast, even before the weight changes, so they want to understand the cellular mechanism behind them 【9】 J Nutri: scientists confirm the long-term health benefits of low-fat diet doi: 10.1093/jn/nxz107 recently, an International Journal of the Journal of In the Research Report on nutrition, scientists from the Fred Hutchinson Cancer Research Center identified multiple health benefits of low-fat diet for women through research They found that low-fat diet can reduce the death rate of individual due to breast cancer and slow down diabetes mellitus as much as increasing fruits, vegetables and grains To prevent the occurrence of coronary heart disease Researcher Ross Prentice et al Started a dietary modification trial in 1993 In this study, researchers studied about 49000 postmenopausal women from the United States to see whether the low-fat diet pattern could reduce the risk of breast cancer, colorectal cancer and coronary heart disease After nearly nine years of dietary changes, the researchers found that the low-fat diet was not clear However, after nearly 20 years of long-term follow-up, the researchers found that
