Experiments in mice prove that obese cells affect intelligence.
The Journal of Neuroscience published a study by Regent University in Georgia. After the mice were fed and accumulated adipocytes, the researchers detected the concentration of interleukin 1 (IL 1) produced by adipocytes in blood, which is a hormone that can cause human inflammatory response.
Through the detection of mouse brain tissue, it is found that when IL- 1 flows to the hippocampus, the memory center of mouse brain with blood, it will reduce the original learning and memory function, make the brain inflamed and make the synapse that transmits information malfunction. The memory and thinking test scores of obese mice are far lower than those of normal mice!
In order to confirm the relationship between fat cells and intelligence, the researchers helped the mice lose weight by liposuction. It was found that when there was no interleukin 1 in the blood of the mice, the mice passed the previous memory and thinking tests as easily as taking brain pills. When fat was implanted into slender mice, they were found to be stupid, and their scores in memory and thinking tests were not as good as before. The research results prove that fat cells are the killer of mental retardation in mice!
The bigger the belly, the worse the memory!
Can fat cells also affect people's intelligence? Scientists want to study whether the size of the stomach affects the structure of the brain. More than 100 subjects were recruited and the ratio of waist circumference to hip circumference and the structure of hippocampus in the brain were measured. The results showed that the greater the waist-hip ratio, the smaller the hippocampus. The size of the hippocampus is the key to affect memory, that is, the bigger the hippocampus, the stronger the memory, and the bigger the hippocampus, the weaker the memory!
Brain volume squeezed by fat!
Later, neuroscientists at Boston University investigated the brain images of 94 elderly people with normal brains in their 70s. After five years of follow-up, we found amazing results! Compared with normal people, the brain images of overweight people have aged for 8 years, and the brain tissue has decreased by 4%. 16-year-old obese brain image, 8% less brain tissue! According to the brain image, the brain tissue squeezed by fat belongs to the middle frontal lobe and temporal lobe of the brain, where decisions are made and memories are stored. (definition of obesity: body mass index above 30; Definition of overweight: body mass index is 25 years old and 30 years old. Body mass index (BMI) = weight kg/height 132 1)
Swedish scientists have also published a 24-year-long medical study, pointing out that for women who are overweight 16%, every increase in 1 kg of fat will obviously reduce their intelligence; Conclusion Obesity can damage the local function of frontal cortex and affect people's memory and language ability.
Can you completely avoid obesity?
A study by Dr. michael green of Aston University in England pointed out that 60%~70% of human brain tissue is fat. Fat is one of the most basic structures of human body, accounting for 15%~30% of the body. Fat not only provides energy, but also forms cell membrane, regulates endocrine, and forms brain tissue and neural network. Proper consumption of oil is very important to maintain the normal operation of the brain.
The report of this website "Eating the right fat can be healthier! It is mentioned that the synthesis of trans fatty acids will increase the risk of obesity, cardiovascular disease and cancer. However, to maintain human health, we still need to consume saturated fatty acids and unsaturated fatty acids. In particular, monounsaturated fatty acids in olives and avocados contain ω-9, which is the key oil of brain nerve cells and should be supplemented appropriately.
