A healthy body in a healthy mind, the argument for as long as we have heard; scientists have found support for this adage in the search. It was found that diets bad can adversely affect mental health in all stages of life, from the growth of the fetus to old age; and found studies recently presented at the annual meeting of the Society for Neuroscience that the Western diet talk is not considered a model where the mother's consumption of these diets may It hinders the development of a child's brain is still in the womb, and that the diet itself can lead to depression among adolescents, as it contributes to dementia, Parkinson's disease among older adults.
Diet and brain teen
Researchers at Emory University School of Medicine in Atlanta that a high-fructose diet may lead to aggravation of disorders such as depression in adolescents. And found a team led by graduate student Constance Harel that rats fed a high-fructose diet for 10 weeks showed hormonal response to a changing stress on the genetic level, were similar to those observed in people who suffer from depression, Harel said that such a profound effect raises human concern, especially during the teenage years, which is considered a critical period for the development of pressure in the brain response.
Obesity and Dementia
Researchers from the Australian National University found that obesity may contribute to dementia. The study was led by Dr. Nicolas Cherbuin which followed 420 healthy adults who were in the 60-year-old at the beginning of the study. The researchers also followed the changes in the bodies of the participants as well as the weight and size of the hippocampus Andkl person, and the hippocampus is a region in the brain play a crucial role in long-term memory; and continued tracking over the period of eight years. The results showed that the weight gain associated with the contraction of the size of the hippocampus rates abnormal, so the obesity affect brain health in older negatively adults. The study also confirmed that obesity leads to an increased risk of dementia and increase the risk of developing zheimer's, it was shown that restricting calories thermal slow the aging process in mice and monkeys.
The researchers also identified at Monash University in Melbourne, Australia, a hormone that can provide the same benefits; all without the need to limit what people eat significantly. And it comes with the hormone ghrelin, or the so-called "hunger hormone" that helps regulate appetite. Team Monash has worked with mice placed on a restricted calorie diet and were genetically modified so that will not produce the hormone ghrelin, and have found that these mice do not live longer than mice that were not on the diet, suggesting that ghrelin may be a key element in providing the advantages of longevity in such a diet.
Then researchers injected the rats with Parkinson's disease hormone ghrelin and found changes in the brains of animals associated with reduced cell loss of paralysis, confirmed Jacqueline Bayliss, a graduate student who presented the study, this is the first phase of the research, but the results are promising for the treatment of Parkinson's disease.
He said Dr. Ralph DiLeone of Yale University, an expert in neuroscience was not involved in any of the research and independent studies, that there is a complex effects of diet and obesity on brain health, mental behavior and functions; and that our understanding of these relationships may eventually lead to the best of several treatments of neurological disorders.
