Its impossible to avoid them. For decades weve been surrounded by sweet and fatty food. And the body has not been dealing well with these eating apples. But what about the brain and. Do our Mental Health our moves and our brain abilities suffer from the wrong kind of nutrition. We know that john feed is making us fat that science is telling us now that it might also be shrinking out right. Brain researchers or join the dining table to study the effects of our eating habits dots a high in fat and sugar in a long term need to change isnt part of the brain floating in. This is a recent field of research on a bell and being science than spotlights a new facet of nutrition. A choice a prefers a violation of Sherlock Holmes and a reprogramming of the brain in short our brain is affected by whats on our plates. You know we started with our very 1st meals even before birth. The brain is built up during pregnancy. Powered functions later on depends on how it has been nourished by the expectant mothers dying at over 9 months. A number of consequences of poor nutrition during gestation no been known for a long time. Todays scientists in australia are looking at the repercussions of nutrition on brain function. Released jacka a professor at the university of melbourne examined the behavior of babies after following the eating habits of 23 columns and pregnant women. We mentioned their intake of drunken courses food squeamish if theyre in type of the Healthful Foods foods with lots of fiber and nutrients etc and then one looked at the Emotional Health all things children over the 1st few years of lost and icing months to 5 years of course taking into account things such as education income the mothers Mental Health parenting practices they sorts of things and what we saw very clearly was that mothers who are more junk and torsos food is so sweet drinks and so to see their son you know type space to during their pregnancy the children had removed these behaviors such a great shame and anger and tension. Just disquieting correlation and suggests that the mothers diet impacts the Mental Development of the baby so the link remains to be demonstrated on the biological level. In any case police junkie is convinced. So what we also saw in this logical wage in studies that the children start saying to be important as well independent of what mum if children were 18 too much junk and processed foods and or not enough of the healthful food they had more of these anger and aggressive top behaviors but also said this anxiety why are you not me. But since then professor jackers conclusion is have been confirmed by studies in spain the netherlands encountered an excess fountain sugar arent. In the sides of scientists working on the brain. Excesses and deficiencies junk food is often low on essential nutrients so it leaves the body and especially the nerve cells lacking. In this laboratory at the university of bordeaux scientists are studying the consequences of dietary deficiencies unmount sprains. This experiment is used to measure anxiety. The animal has the choice between exploring the lighted area or hiding in the shade. The normal mouse takes the time to examine the lighted area. But this animal was deprived of a mega 3 fatty acids during his development omega 3 these are called good friends due to their benefits to the heart and arteries instead of exploring the environment the mouse takes refuge in a dark corner it stretched anxious. The experiment has been reproduced many times on dozens of mice for researchers this strange behavior can be simply explained without omega 3 fatty acids the brain does not develop and function normally. Theyre needed because the brains grey matter is 90 percent fat which it cannot produce it sounds as what the brain is the organ after adipose tissue thats the richest in polyunsaturated fatty acid or in the good 3 wides so in a good 3 is indispensable because the body cannot make it we have to ingest it it has to come from the diet all men want as your. Coralie fish. Organ meat version real oils and seeds and not such as all mens have long been the main sources of our major 3 for humans but these foods have become scarce in the cuisine of industrialized countries. The amount of omega 3 that enters the brain is crucial for making brain cells more efficient because when these fatty acids are incorporated into the membranes of nerve cells they improve their Electrical Properties you know make it 3 rich neurons the signals propagate faster. The network is more efficient depriving the brain of omega 3 is linked to a risk that it will function less well. Ive looked at the source and the general population is deficient and im to get 3 we have insufficient intake of a nigga 3 so its important to Pay Attention to it especially in the prenatal developmental period during this period omega 3 embeds itself in must of quantities into the brain also in adolescence when theres often a change of food and during aging where the incorporation into the brain of a mega 3 tends to be less effective so we must increase its intake a wanted a closer look at. The 1st rule for a brain to run at full speed is avoid differences. For good nutrients and a very dark should be available what happens to neurons when meals are poor and above all always the same there is a problem that is now affecting the while living european hamster which thrived for a long time in the planes or francis us us which are. Safe and 1960 s. Theres been a decline in the hamster population which is on the verge of extinction today and at the same time weve noticed an increase in the agricultural area where corn is cultivated. Carlene are bored wondered whether the collapse of the population was linked to the sudden clucked of corn. So she did an experiment feeding hamsters exclusively corn. During breeding we have served behavioral disturbances in females which resulted in hyper aggression and hyper sensitivity as soon as there was noise in the room now we want to. Change clothes. And. Above all what we did not expect is that these females would devour their young the 1st day after birth this behave. It was observed in more than 80 percent of females. That dietary deficiency was enough to make a hamster devour its children because a simple vitamin. Think of vitamin b 3 deficiency is at the origin of the abnormal behavior when we supplemented them with vitamin b 3 in addition to their corn based diet they expressed quite normal behaviors and they began to nurse their young to raise them in the same way as the females that were fed a diversified diet since. The case of the cannibalistic hamsters is disturbing. Could an unbalanced diet also trigger aggressive violent behavior in humans. Up suburb is a clinical psychologist and political advisor to the Dutch Ministry of justice his specialty nutrition and crime. Hes convinced that enriching food with vitamins fatty acids and minerals can reduce aggression. Its a hypothesis that is difficult to test in normal life because so many factors and circumstances can influence our behavior and our impulses. You know order to study nutrition without the influence of the many parameters he chose prisms as a nearly ideal setting. It neednt have been and here in the netherlands we conducted a study of young prisoners in 8 different prisons who do all of the demand for 3 months we get them vitamins and minerals and fatty acid supplements and then we looked at the effect on their behavior. We measured it in 2 different ways of locked doors at the far end of the 1st we asked the detainees how aggressive they were and we asked the supervisors for their views on the issue incident also above all we looked at the incident log the number of times detainees were punished and we saw that solitary confinement had fallen dramatically. Slink off the wall but i have decided that. In the group of inmates whose meals were improved the number of incidents was reduced by one 3rd. Of. What we may have the power to change or move to stimulate certain impulses. But could the food on our plate also influence our decisions the ones we believe we make using our free will. As a venue and then mentioned when i pull or asked if they think that the food that they eat has an impact on health and most answered yes. But when asked if diet can also influenced thoughts and decisions very few people are willing to believe this is the case and this comes you feel a lot in it for us then. However at the institute of psychology of the university of liberty in germany professor so young parklands with the 1st time prove. That. Her work reveals the mechanism by which food could influence our thoughts and for that the researcher has developed a rather original experiment. Imagine that you face the following dilemma. The money on the table is to be divided into 2 sums but its your partner a stranger who decides how it is to be distributed. I give you to yours and i keep a for me. If you accept the unfair offer you leave with a little money but much less than your partners. If you refuse no one wins anything so what would you do. Do you accept the offer and take the 2 year olds even if you feel cheated or do you refuse and leave with empty pockets but your head held high. Well it turns out surprisingly that whether youll take the money or not depends on what youve just eaten. And his are stored as part of this study we follow 24 people who came into the laboratory twice to have 2 different breakfasts. For us via 1st then one we found that the same person made completely different decisions based on what the ate in the morning and then. To the test person the do breakfasts look the same in reality one is a far more protein rich than the other. The ratio of protein to sugar is the only parameter the changes. A few hours after the meal the subject takes several test on a computer. Today he accepts the offer his selfinterest outweighs his anger at the unfairness and he will leave with a little money in his pocket. Last week he mainly refused and one almost no. One fed the poor but the subject having consumed a high protein breakfast in the morning was tolerant of unfair offers tolo. Unfit us on get what feel like yet conversely the subject to consume the high carbohydrate breakfast habits was less tolerant in the face of unfair offers yet. On average the subjects who had little protein rejected unfair offers this wise is often. But how can the surprising result be explained in their search for biological evidence for this observation the scientists carried out blood tests and will send the blood to low bar chief analysis will measure the level of hormones and amino acids in the blood i mean the whole moans were interested in insulin cortisol adrenaline and adreno cortico tropic hormone and for amino acids trip to fun and tyras in total followed tools in. Of these substances the most important is tyrosine the amino acid is one Building Block of a protein that is key to brain function dopamine. This molecule ensures communication between neurons involved in motivation and risk taking. The results of the Blood Analysis show that subjects with higher levels of timers in their blood are more willing to accept the unfair offer. You know other words what we eat can within hours subtly alter the chemistry of the brain and thus the communication between the neurons. Enough to guide some of our decisions. Experiments are continuing in the back to confirm this result the implications are wide ranging. Remember there. That sense i eat 3 times a day every day is we realize that food has immense power that of modifying and shaping mankind norm and so its essential to think about how we can use food to promote our wellbeing and optimize our mental state. Or to oh its up to me and. Not only does an unbalanced diet affect our brain functions and behavior and our meal plan interfere with daily decisions it also becomes increasingly clear that diet plays a decisive role in our mood and possibly Mental Health. But what about junk food dripping with sugar and bad fats. And what would happen if we ate more of that heat. This is the focus of research here in australia at the university of sydney. Margaret morris runs a laboratory where rats are fed the kind of junk food that you find in supermarkets for cheap fast food restaurants. Eriks parents use a range of western foods at the time a can buy all of us so we feed our rats meat pie chips cakes and biscuits the sorts of foods that are vettel a valuable and cheap so well model in the western world. The 1st consequence of this diet the rat doubles its food ration as. The animal never seems to share. But thats not the most surprising outcome. One of our chief interests is the impact of his diet on the animals memory and we can measure this is lee in the rat using a task known as the novel object and novel place task. In this test the researcher places objects in the rats cage. The animal comes over immediately to examine that. Rodents are very curious by nature. Once its completed its examination and memorized its surroundings its temporarily removed we then place the animal in the arena with one object thats been shifted. On its return the rat spends more time examining the object that is changed places because it already knows the other objects there engraved in its memory. The rats are stuffed full of bad foods or behave differently. What we observed is the animals eating a high fat diet or a high sugar diet or the combined high fat high sugar foods were less able to recognize to remember that that object had moved the explorer the 2 objects a path a sign that shows any payment at this spatial memory. The overfed rants have not only damaged spatial memory but also other malfunctions that sound a warning signal from the scientists they point to damages in the hippocampus a small region nestled in the center of the brain. Its essential for learning and the consolidation of memory. Recent studies show that in humans like to energy rich diet also interferes with the hippocampus. They say for example that the quality of peoples diets is related to the size of the hippocampus to the size of the gray and white mesh of value and theyre starting to be intervention studies so for example we say that only 4 days on junk food top diet will have an impact on culpas you functions that are related to the hippocampus. For Margaret Morris is now seeking to understand how sugary and fatty foods disrupt the brain of her rats to the point of affecting their performance. She has a hypothesis namely eating too much fat and sugar triggers an inflammatory reaction that spreads to the neurons. So in response to these foods theres a general inflammatory response all around the body this is being botha scribed in obesity but it now appears to be caught in acute response as well and what we find is that inflammatory molecules such as saudi concept increased in response to the dives. And overly rich direct confuses the immune system. It responds by triggering an inflammatory reaction especially in fatty tissues. Are fat mausers released substances that then propagate this inflammation throughout the body. Neurons were thought to be spared this effect behind the protective blood. Same barrier this i mean permeable membrane that separates the circulating blood vessels from the brain. So this increased inflammation in the halls the body and we think that this may spread to the brain. Thats because the blood brain barrier which normally protects the brain from inflammatory molecules may be impaired in fact by the time that and become leaky allowing traffic of molecules into the brain. The inflammation infiltrates them in n. G. s and then triggers a surprising phenomenon. In our laboratories so feel a has shown in her overfed mice that certain immune cells in the brain to mark rogue little cells begin to devour neurons. Considering these microbial souls within the brain are important because they can eat dead neuroses live in the hood when theyre deregulated especially in a situation of on Balance Nutrition they start to eat near owns the to realize their full by consuming these neurons in excess of numbers eventually they will destroy all participate in the destruction of Neural Networks this way that includes neurons that are alive and that should be functional duvet force and. This reaction of the micro global cells could be filmed in vitro. All the images show how energetically they move. The red objects or fragments of neurons that they ingest all in an obese mouse the activity becomes frenetic all mr nominates suspected of significantly affecting the functioning of the brain. War that. Weve been signed to people for 30 years dont eat things fade she might have a heart attack you might get cancer and diabetes it hasnt worked to change peoples behavior we hope that if people understand that what they put in their mouth is actually really essential to the health of their bryant. And that of the children that might have a more profound impact on peoples daughtry choices. Microscope micro manipulator and ultra sensitive recording. Serve you for what i meant is at the helm of an apparatus that can record the electrical activity of a single neuron the principle is simple a slice of mouse brain is immersed in a liquid that keeps it alive. The researcher approaches it carefully with an electrode. Its a meticulous operation. Its usually thought here i go down the people that in the slice of brain you need to know and now we will approach this recording people at near the neuron to make contact. Thats it we made contact and now we will be able to measure the electrical activity of the nereid that he did it to get in on. It he can go up and peaks that we see a potential areas for action yeah but in the quote it this is how humans in code information. The time that he lapses between the peaks is the message sent by the neurons. And then to normal now we will increase the glucose concentration in the bath and we will see if this cell responds to this increase in concentration of glucose because. As they can be seen here this cell responds to the increase with more electrical activity but there is more potential for action than what could be seen here before the increasing to cause concentration. In this signal comes from a single cell but in the brain the neurons are all connected to each other and. That makes the scientists suspect that glucose has the ability to modify the activity of an entire brain areas in the control emotions and pleasure. Is this how sugar ensures its grip on our will. This is for the moment only a hypothesis but today sugar addiction is the subject of Intense Research in laboratories and what appears more and more clear is that the power of sugar is similar to that of a drug. Search up magic is one of the 1st to provide proof with a very simple experiment. Step one he raised rounds giving them cocaine and sugar. Man after weeks of this diet he presented the an
