there is no getting away from this abundant, too sweet food with unhealthy fats, it surrounds us everywhere | |
0:17 | |
and the body suffers from these new eating habits for decades | |
0:22 | |
Rafael and those but how is our brain | |
0:28 | |
mental health our mood our mental abilities whether they depend on | |
0:34 | |
unhealthy appetite it is known that from junk food cold steel | |
0:39 | |
but science now tells us that in addition, the brain shrinks from it, tie napkins, scientists go to the table | |
0:49 | |
food rich in fats and sugar leads to changes in those parts of the brain that | |
0:55 | |
associated with memory is a recent area of research, a new science that | |
1:01 | |
reveals new levels of healthy nutrition significantly and the consumption of fats and sugars | |

reprograms Moscow time what comes to your mind depends and | |
1:14 | |
from what you put on your plate a healthy diet for a healthy brain | |
1:22 | |
[music] | |
1:28 | |
it all starts with the first meals before birth | |
1:34 | |
[music] the brain is formed during pregnancy | |
1:41 | |
subsequently, its development depends on what it was fed and on what I | |
1:46 | |
break within 9 months | |
1:53 | |
and has long been known for the impact of poor nutrition on a child's health | |
2:02 | |
but today Australian scientists are wondering what implications nutrition has for | |
2:08 | |
brain work Phyllis Jaka from Melbourne | |
2:15 | |
university one of the best specialists in the following connection between nutrition and the brain | |
2:21 | |
she studied the behavior of thousands of children before tracing their eating habits | |
2:26 | |
mothers during an extensive follow-up that targeted 23,000 | |
2:31 | |
pregnant women, we measured the amount of food they ate as junk caloric | |
2:38 | |
useless and healthier rich in nutrients and fibers Professor Phyllis Jaka Melbourne | |
2:45 | |
university and then we studied the emotional manifestations of their children in the first 5 years of life of course we | |
2:52 | |
took into account aspects related to education, income and mental health of parents, we stated and | |
3:00 | |
it was conspicuous that mothers whose diet during pregnancy | |
3:05 | |
reduced to genetically modified foods sweet drink and salty snacks and | |
3:11 | |
children were born subsequently with a more prone to allergies, short-tempered and moody, this is disturbing | |
3:19 | |
the relationship suggests that maternal nutrition affects the mental health of the child remains to be proven | |
3:26 | |
at the biological level, Phyllis Jaco is convinced of this anyway [applause] | |
3:34 | |
this Norwegian study also allowed us to know that the nutrition of the child is of the same importance | |
3:40 | |
like nutrition, oil, an excess of junk food, a lack of healthy foods provokes irritability | |
3:48 | |
and aggressiveness and also causes sadness anxiety anxiety or nightmares | |
3:56 | |
later, the conclusions that Professor Jack came to were confirmed by research | |
4:01 | |
carried out in spain the netherlands and a rope there is a relationship between the quality | |
4:06 | |
nutritional problems and mood swings in children, but what is the relationship in what way | |
4:12 | |
food interacts with neurons | |
4:17 | |
[music] excess fat and sugar is now under the guns of brain scientists | |
4:24 | |
only excess and lack of food saturated with spenders junk food where | |
4:30 | |
often missing nutrients does not provide all that the body needs and especially on and ronom | |

bordeaux francis in this bard university lab | |
4:44 | |
scientists study the effects of nutritional deficiencies on the mouse brain | |
4:50 | |
[music] | |
4:59 | |
this experiment serves to measure anxiety the animal has a choice | |
5:04 | |
explore the illuminated part or hide in the shade | |
5:10 | |
a normal mouse always explores the lit part | |
5:18 | |
but this mouse was deprived of omega 3 during the growth period. omega 3 are healthy fats | |
5:25 | |
known mainly for beneficial effects on the heart and arteries instead of exploring the environment | |
5:33 | |
the mouse hides in a dark corner and does not come out anymore; she is stressed, she is anxious | |
5:40 | |
the experience has been replicated many times on dozens of mice for researchers to | |
5:46 | |
strange behavior is explained simply without omega 3, the brain cannot work properly because our gray matter | |
5:52 | |
90 percent consists of fat which itself but does not know how to produce | |
5:58 | |
[music] brain organ after adipose tissue most | |
6:04 | |
rich in fatty polyunsaturated acids which are also called omega-3 Dr. sophie lagi university burda these | |
6:12 | |
omega-3s are essential because the body cannot produce them, they must be obtained from food | |
6:18 | |
oily fish giblets vegetable oils nuts have long been the main | |
6:24 | |
sources of omega 3 for humans, these foods are now less common | |
6:29 | |
meet in the kitchens of industrialized countries [music] | |
6:38 | |
with fila and wanted to go further and understand what was wrong with the brains of these anxious mice | |
6:44 | |
which were deprived of omega 3, she closely examined them in iran and and under | |
6:51 | |
anomalies are clearly visible under a microscope here neurons and branch they have everything | |
7:00 | |
these continuations do not occur in the case of omega-3 deficiency if studied | |
7:06 | |
it can be seen in more detail that the number of connections of neurons represented by these small | |
7:12 | |
protrusions on these synapses also decreased and this shows the impact | |
7:19 | |
deficiency of omega dreams on neuron connectivity in the brains of these mice | |
7:26 | |
means without omega 3 necessary for the development of on and ronom it is difficult to communicate | |
7:31 | |
among themselves because the very structure of the cells is changed | |
7:40 | |
press the omega 3 that we consume will enter the brain and the membranes of neurons will be embedded in rendering they are embedded | |
7:47 | |
give these neuronal membranes greater flexibility and help neurons connect better with each other | |
7:54 | |
how much omega 3 penetrate the brain depends on the efficiency of brain cells | |
8:02 | |
because when these fatty acids are incorporated into membranes they improve their electrical properties in neurons | |
8:09 | |
rich in omega 3 signal spreads faster the system is more efficient to deprive | |
8:15 | |
omega 3 brain means risking its performance deterioration a [music] | |

8:28 | |
not enough means it is important to keep an eye on it pay attention to it as | |
8:33 | |
especially in certain periods such as the period of development from you when these acids in large quantities, the hydra is in | |
8:40 | |
the brain is also important for adolescents because at this age nutrition changes and also during aging when | |
8:48 | |
omega-3 is absorbed worse by the brain, which means it is necessary to increase their intake alsace | |
8:54 | |

since the sixties there has been a decrease in the population of hamsters Dr. Caroline will be the center of scientific | |

research at the University of Strasbourg and today they are on the verge of extinction and at the same time we see that more and more | |
9:37 | |

and most importantly, this is whom we did not expect females ate their cubs in the first | |
10:21 | |

they began to nurse their cubs; rest; raise them like females who received | |

the Dutch archives of the last world war gave scientists the opportunity to study this issue | |

12:24 | |
he specializes in the connection between food and crime he is convinced that by enriching | |
12:30 | |
food with vitamins, fatty acids and minerals can reduce aggressiveness | |
12:39 | |
it is difficult to test this hypothesis in real life because our behavior | |
12:44 | |
impulses can be influenced by many circumstance factors in order to study nutrition in near-ideal conditions without | |
12:51 | |
influence of many aspects he chose prison | |
13:00 | |
about the beginning of the experiment voluntarily participate in which he volunteered 221 | |
13:06 | |
concluded on an apple here in the netherlands we spent | |
13:12 | |
study of young prisoners from eight different prisons 3 mana gave zero | |
13:19 | |
them dietary supplements with vitamins, minerals and fatty acids and then watched how it | |
13:26 | |
affects their behavior we evaluated the result in two different ways, first we asked ourselves | |
13:33 | |
prisoners how aggressive they feel afterwards and asked what the guards think about it, but the main thing is we | |
13:41 | |
watched how many incidents were registered how many times the prisoners were punished and saw that in the ring | |
13:48 | |
were planted much less frequently in the group of prisoners who received | |
13:55 | |
improved nutrition the number of incidents decreased by a third | |
14:03 | |
the same studies conducted in British and Australian prisons led to the same conclusion minerals | |
14:10 | |
omega-3s and vitamins as a dietary supplement reduce violence | |
14:16 | |
[music] | |
14:25 | |
yes, dad, for the next stage, we need to check whether our scientific discoveries can be put into practice, we have a lot | |
14:32 | |
joint projects with the prison administration, we will see if dietary changes can be considered as | |
14:38 | |
way to influence aggressiveness means that what we absorb is capable of | |
14:45 | |
change our mood stimulate certain urges [music] | |
14:52 | |
but can the contents of the plate influence our decisions, which we think | |
14:59 | |
accept freely when we ask people professor | |
15:06 | |
sooyoung park university love whether they think the food they eat for | |
15:12 | |
affects their health, the majority answers yes, but when their | |
15:17 | |
they ask if nutrition can also affect thoughts, but very few people are ready to decide | |
15:25 | |
to believe that this is a fact there is any germany however in a very serious | |
15:32 | |
Institute of Psychology of the University of Lübeck in Germany Professor Suyoung Park for the first time | |
15:38 | |
this was proven in her writings, she traced how food can | |
15:44 | |
to influence our thoughts for this researcher rule is a rather unusual experiment | |
15:53 | |
imagine that you have to solve the following divide the money lying on the table should be divided by | |
16:01 | |
that part but decides how to share them your playmate is a stranger | |
16:08 | |
I give you two euros and keep 8 for myself | |
16:13 | |
if you agree to this unfair offer you will get some money but much less than him if | |
16:21 | |
refuse no one gets anything and how do you do you accept the offer and take 2 | |
16:29 | |
euro though you feel cheated or refuse and leave with empty | |
16:34 | |
pockets but with your head held high, so it turns out that you will take | |
16:41 | |
money or not take depends on an unexpected condition on the fact that you | |
16:46 | |
before that they ate [music] | |
16:59 | |
I know they made you breakfast the only thing you have to do | |
17:04 | |
sheep eat everything later I'll be back and we'll have a second | |
17:10 | |
part of the bon appetit experience | |
17:20 | |
in dieser in the framework of this experiment, we examined 24 people, they twice | |
17:27 | |
came to the laboratory and ate two different breakfasts, we made sure that the same | |
17:34 | |
a person makes completely different decisions depending on what he is talking about. | |
17:40 | |
ate in the morning | |
17:45 | |
to the test subject, both breakfasts looked the same, in fact, one had | |
17:51 | |
much more protein than the other, the only variable was the ratio of protein to sugar | |
17:58 | |
within a few hours of eating, subject ran multiple tests on the computer | |
18:05 | |
only he is inclined to accept the offer, the benefit to him outweighs | |
18:10 | |
his displeasure he walks away with a small amount of money in his pocket [music] | |
18:15 | |
last week he refused and earned almost nothing | |
18:21 | |
he tissues after breakfast you who were rich in proteins | |
18:29 | |
the test subjects calmly perceived the unfavorable offer of anke bukei opposite | |
18:35 | |
after breakfast rich in carbohydrates glass he was more intolerant of them angie bot | |
18:44 | |
rockets on average, a person who received little protein was twice as likely to reject | |
18:51 | |
a fair offer but how to explain such an amazing result in order to understand it back up this | |
18:59 | |
biological evidence observation scientists conducted blood tests available | |
19:05 | |
hand we send the blood for analysis and the analysis in the laboratory itself measures the level of hormones and amino acids | |
19:11 | |
in your blood without hormones, we are interested in insulin cortisol adrenaline and | |
19:17 | |
corticotropin a from the amino acids tryptophan and tyrosine | |
19:28 | |
the main item on this list tyrosine is an amino acid that is part of a very | |
19:34 | |
the brain-important neurotransmitter dopamine, this molecule provides a message | |
19:41 | |
between neurons associated with motivation and willingness to take risks | |
19:49 | |
test results show that those with higher levels of tyrosine in the blood are easier | |
19:54 | |
agree to an unfavorable offer of you, we assume that | |
20:02 | |
increasing the level of tyrosine in the blood increases the amount of dopamine in the brain | |
20:08 | |
which in turn influences behavior. | |
20:13 | |
in other words, what we eat in a few hours does not noticeably change | |
20:18 | |
the chemistry of our brain, and hence the communication between neurons, is enough to | |
20:24 | |
to influence some of our decisions experiments at the Institute of Psychology Lübeck to confirm this | |
20:30 | |
conclusions continue because we are talking about an event in which a lot of things are affected | |
20:37 | |
we eat every day three times a day and understand that food has a huge | |
20:44 | |
power, it can change and shape a person, which means it is necessary to think about | |
20:51 | |
how we can use food to make us feel good or improve our state of mind | |
21:02 | |
nutritional deficiencies relax the brain affects mood diet depends on decision | |
21:08 | |
in everyday life we understand that food plays | |
21:13 | |
primary role in our spiritual life | |
21:19 | |
we [music] | |
21:28 | |
but how then is it with useless food overflowing with sugar and unhealthy fats what would become of us | |
21:35 | |
if we didn't eat anything else | |
21:41 | |
Sydney, Australia | |
21:48 | |
this has become the subject of research being conducted here in Australia at the University of Sydney | |
21:56 | |
[music] | |
22:03 | |
Margaret Maurice runs the only laboratory in the world where rats are fed harmful | |
22:08 | |
food that you buy in supermarkets and that you are served in cheap | |
22:14 | |
eateries | |
22:25 | |
and in our experiments we use what everyone eats in Western countries professor | |
22:30 | |
blink Morris NSW all would we give our rats quiche fries cakes and | |
22:38 | |
biscuits are inexpensive and ready-made; we reproduce the eating habits of the Western | |
22:44 | |
world first consequence of rats county doubled | |
22:50 | |
the animal is never satiated but that's not the most amazing thing | |
23:03 | |
he our main research topic is related to the effect of such nutrition on | |
23:08 | |
memory, we can easily measure it using the position recognition test | |
23:14 | |
items for this, the researcher places | |
23:20 | |
the object next to the rat then immediately goes to study them because | |
23:26 | |
rodents are naturally very curious once the animal is done exploring | |
23:32 | |
and remembers the environment it is carried away for a while | |
23:39 | |
then the animal base is placed next to the object that has been moved during this time | |
23:45 | |
[music] | |
23:53 | |
when the rat returns, it takes longer to study the object that has shifted, because the rest it has already | |
23:59 | |
knows he is imprinted in her memory | |
24:04 | |
[music] perry fed rooftops behave | |
24:10 | |
in another way, we noticed that rats that eat very | |
24:18 | |
fatty or very sweet or both fatty and sweet foods are hardly aware that | |
24:24 | |
adopted moved, in contrast to rats that received healthy food, those who | |
24:29 | |
fed fat and sweets spent the same amount of time studying subjects, indicating changes in | |
24:35 | |
spatial memory u perrie fed them rats not only | |
24:41 | |
spatial memory is damaged they have other disorders that scientists perceive as an alarm signal | |
24:51 | |
they're talking about changes in the hippocampus that's a small area of the brain needed | |
24:57 | |
for learning and for reinforcing memories, and recent studies show that | |
25:04 | |
human overnutrition also affects the hippocampus | |
25:13 | |
[music] of example revealed not only connection | |
25:20 | |
between nutrition and hippocampal size but also the relationship with gray matter and white matter other studies | |
25:27 | |
four days of malnutrition were shown to be affected by cognitive | |
25:34 | |
functions that depend on the hippocampus 40 you ordered coca cola it tastes good to me | |
25:43 | |
I don't care what it tastes like, can I have fried potatoes too? | |
25:53 | |
Are our new eating habits really threatening our memories of our | |
25:58 | |
mental faculties for categorical statements is still too early | |
26:05 | |
but the signs are piling up and worrying scientists | |
26:11 | |
Marguerite Maurice is now trying to figure out how too much food | |
26:16 | |
affects the brain of rats to such an extent that it impairs its functioning | |
26:24 | |
the hypothesis suggests itself excess fat excess sugar causes | |
26:30 | |
an inflammatory response that spreads to neurons | |
26:38 | |
these foods cause an inflammatory response in the body, the mechanism is well understood in obese people, but | |
26:46 | |
it seems that this is also an acute reaction, we were convinced that the level of inflammatory | |
26:51 | |
molecules grows depending on nutrition | |
26:59 | |
too much food confuses the immune system | |
27:07 | |
it is lost and triggers an inflammatory response particularly in fatty tissues | |
27:13 | |
[music] our fat masses release molecules | |
27:18 | |
which then spread this inflammation throughout the body, it was previously believed that Iran and reliably | |
27:25 | |
sheltered and behind the blood-brain barrier am the sheath surrounding the blood vessels | |
27:31 | |
vessels and the protecting brain, this phenomenon does not affect | |
27:39 | |
the inflammation that builds up in the body spreads to the brain, the fact is that | |
27:46 | |
the blood-brain barrier which normally protects the brain from inflammatory and inflammatory molecules can be damaged due to | |
27:53 | |
nutrition and become porous in the form of alam in these holes and the molecules pass | |
28:01 | |
rats were observed as a response to food changes in the level of inflammatory | |
28:07 | |
molecules inside the brain and it has been linked to memory loss | |
28:12 | |
[music] inflammation that covers the meninges leads to completely | |
28:18 | |
amazing phenomenon in my lab with fila and just | |
28:23 | |
showed in spite of their mice that some immune-related brain cells, namely microglial cells | |
28:30 | |
begin to absorb neurons | |
28:36 | |
these micro glial cells inside the brain are very important because they can | |
28:42 | |
absorb dead neurons but in the absence of regulation and in particular | |
28:48 | |
with an unbalanced diet, if they begin to eat live grains and that is, in fact, immoderately | |
28:55 | |
absorbing the neuron, they will eventually destroy the caps; in any case, they will contribute to the destruction of the neural | |
29:02 | |
connections and living neurons in which the reaction of microglial cells should work was filmed in | |
29:09 | |
in a test tube, they are the ones that move in these images | |
29:15 | |
the fragments of neurons that they absorb in the obese are also marked in red. | |
29:22 | |
mice this activity is running rampant now suspect it is | |
29:27 | |
phenomenon inside neurons significantly impairs brain function | |
29:39 | |
for 30 years people have been told to cut it you will have a heart attack you will get sick | |
29:46 | |
cancer or diabetes but it hasn't changed eating habits in the slightest we hope | |
29:51 | |
what if consumers understand that what they eat is really important for the health of their brains and the health of their children | |
29:59 | |
will have a greater impact on food choices | |
30:08 | |
[music] you can realize that some eating habits harm the brain | |
30:14 | |
but how to resist the temptation desire is often overpowered by junk food | |
30:21 | |
especially sugar glucose constantly pushes us down a dangerous path sugar is accused of | |
30:28 | |
manipulation in that he deceives our other runes [music] | |
30:41 | |
the microscope is now a manipulator and is very sensitive and a recorder to an owl palmistry controls the machine | |
30:48 | |
capable of recording the electrical activity of a single neuron | |
30:58 | |
the principle is simple a slice of a mouse brain is immersed in a solution that keeps it alive | |
31:10 | |
the researcher carefully approaches the electrode to it very delicate operation | |
31:18 | |
doctor xavier a multi university bards i dip the pipette in the funds | |
31:23 | |
of the brain, now we will bring this electrode to the eron to establish contact and contact is declared, well, and | |
31:32 | |
here is the contact and now we can measure the electrical activity | |
31:38 | |
neuron's upper peaks that we see are | |
31:45 | |
peak potential and in this way to iran and encode information | |
31:51 | |
the time that passes between the peaks this message is sent by another ron | |
31:57 | |
nathan now we will increase the concentration of glucose in the solution | |
32:03 | |
we will see if this cell responds to an increase in glucose and comp | |
32:09 | |
how can we see the cell responding to an increase in glucose electrical activity increased | |
32:15 | |
the action potential here is better than it was before the increase in glucose | |
32:21 | |
here the signal comes from one cell all my brain wounds are interconnected | |
32:30 | |
scientists suspect that glucose can change the activity of entire areas of the brain | |
32:35 | |
those who control emotions with pleasure | |
32:45 | |
this is how sugar takes possession of our will while this is just a hypothesis | |
32:52 | |
but sugar addiction has now become the subject of laboratory research | |
32:58 | |
[music] and it becomes more and more obvious that the power of sugar is akin to power | |
33:05 | |
drug | |
33:18 | |
Serge Amed was one of the first to prove this with a very simple experiment. | |
33:26 | |
first he raised rats by giving them cocaine and sugar | |
33:34 | |
then after a few weeks of this diet, he presented the animals with a choice | |
33:40 | |
[music] windows so before us the situation the animal has a choice between the lever | |
33:46 | |
connected to a syringe containing a solution of the drug Dr. Saoirse Medical Center for Scientific Research | |
33:52 | |
bourdon university and this is hard drugs like cocaine and heroin and other leverage on the left it allows | |
34:00 | |
to control another syringe that contains a sweet drink, we see that the animals choose a sweet drink | |
34:07 | |
rats are 4 times more likely to choose sweet water than drugs | |
34:15 | |
Glucose overdose will not happen, but an irresistible desire exists | |
34:20 | |
[music] so this simple experience proves that sugar is more addictive | |
34:27 | |
than it seemed to us until now and maybe even more powerful than hard drugs | |
34:33 | |
like cocaine or choose | |
34:40 | |
[music] like like | |
34:45 | |
[music] skin today we live in a pretty crazy food environment sugar | |
34:52 | |
appears in many products of course among them those in which we expect it | |
34:57 | |
find, for example, in sweet drinks, but we will find it where there should not be sugar, for example, after all, the wife and beat the soup | |
35:06 | |
other examples could be given. Adding sugar to these products will help people | |
35:13 | |
imperceptibly for them, dependence will appear | |
35:25 | |
so we are all really drug addicts addicted to the chocolate bar and the sugar hidden in most | |
35:31 | |
products from the supermarket, is it capable of causing the same addiction in humans as in rats | |
35:40 | |
eugene usa [music] | |
35:45 | |
the effect of sweet food on the human brain is precisely what is being studied here at the Oregon Research | |
35:51 | |
institute | |
35:57 | |
from aspro this research program has shown that consumption is usually | |
36:02 | |
calorie-rich foods affect brain activity as well as | |
36:07 | |
drug use erix toyz scored a hundred students | |
36:14 | |
half of whom are accustomed to overeating ice cream while others never have it. | |
36:19 | |
did not eat all they came to the laboratory to drink a milkshake inside | |
36:25 | |
MRI machine and give away the secret of their brain activity | |
36:31 | |
rolling off today we'll give you a chocolate milkshake and record your brain activity in | |
36:38 | |
the moment when you drink it and just before that it is about | |
36:43 | |
to study the effects on neurons of eating high-calorie foods | |
36:54 | |
I create it very simply you will drink | |
37:01 | |
milkshake and you just need not to move holding the cocktail in your mouth for 5 seconds you | |
37:08 | |
you can swallow it, we will repeat this experience several times | |
37:15 | |
with the help of ordinary straws, the subjects drink a cocktail without turning their heads | |
37:22 | |
Dr. Eric Sykes Oregon Research Institute, we found that people who don't eat ice cream have a system | |
37:28 | |
rewards turn on easily and react very strongly, but those who often eat ice cream have an arc reaction | |
37:35 | |
activity almost does not increase, which proves that the constant use of high-calorie foods reduces | |
37:43 | |
the pleasure they get when they eat the reward system this area of the brain | |
37:50 | |
controlling sensations of pleasure she is especially sensitive to the consumption of sugar, but if there is too much of it in | |
37:59 | |
eventually her ability to respond decreases with equal doses of pleasure | |
38:04 | |
less very interesting that people who constantly use cocaine or other | |
38:10 | |
drugs have similar tendencies to get the same pleasure they need to increase the dose | |
38:17 | |
the fact is that the response system of the reward weakens when they use too much of what | |
38:24 | |
gives them pleasure in other words to get their dose | |
38:30 | |
more and more of this is required, which means, like in a rat, sugar affects | |
38:35 | |
on our brain like a drug and it can cause a person the same | |
38:41 | |
addiction the scientific community has not yet come to an agreement | |
38:50 | |
but Eric Stice's experience revealed another phenomenon that could be even more dangerous and | |
38:55 | |
after a diet too high in sugar, the brain becomes hypersensitive to | |
39:01 | |
picture of food | |
39:07 | |
at home but also jim the more ice cream you eat the less your system reacts | |
39:12 | |
rewards for it turns on much more actively when you see a picture telling you to maybe | |
39:20 | |
you can listen to this the system turns on at full power when you see the kiosk | |
39:26 | |
with ice cream passing by in a car or and advertising ice cream on TV and | |
39:31 | |
acts much more actively in those who often eat ice cream than in those who do not when the same mechanism induces | |
39:37 | |
eat without feeling hungry and leads to obesity and all its attendant problems | |
39:43 | |
The direct impact of food on our brain plays a crucial role in our daily food choices. | |
39:52 | |
eating behavior is extremely complex phenomenon | |
39:58 | |
it's about the health of society and it makes scientists explore everything | |
40:03 | |
mechanisms that govern our daily decisions | |
40:12 | |

Carlos Ribeiro laboratory at the forefront of food choice researchers | |
40:42 | |
from no we want to find all the constituents of Dr. Carlos Ribera Research | |
40:47 | |
the center of shamballa we are lisabon diana molecules neurons that control food choices and for this we need to conduct | |
40:54 | |
very fine research | |
41:00 | |
the simplicity of his fly model allows for new avenues and new hypotheses to be explored | |
41:08 | |
[music] in order to understand the feeding behavior of the fly, Carlos Ribeiro developed a device | |
41:16 | |
which allows you to follow in the smallest detail the choice of an insect starting to eat | |
41:23 | |
vanya common when a fly touches the food of the sensor it shows us approximately | |
41:29 | |
the same as used for the tactile screen of a tablet or phone, only here it recognizes not a finger, but | |
41:37 | |
contact with food and this allows us to accurately analyze the choice that | |
41:42 | |
make a fly between protein and sugar, besides how it is in what | |
41:48 | |
quantity at any speed with what frequency we can really analyze all the details of decisions | |
41:55 | |
which control the brain thanks to this technique carlos proved | |
42:01 | |
that food choices are driven primarily by scarcity | |
42:06 | |
it is natural that flies that lack proteins prefer food rich in proteins | |
42:12 | |
but looking more closely, Carlos noticed that this is not always the case | |
42:20 | |
sun time we noticed that some flies are never attracted to proteins | |
42:27 | |
we tried to understand why you found that the intestines of flies that do not | |
42:32 | |
interested in proteins colonized by bacteria through many experiments we have proven | |
42:40 | |
the existence of two specific bacteria that suppress cravings for | |
42:45 | |
proteins, that is, these two bacteria are very strong | |
42:50 | |
affect the desire to eat brain proteins | |
42:56 | |
flies choose their food under the influence of bacteria present in their intestines | |
43:05 | |
this unexpected discovery certainly raises an important question | |
43:10 | |
bacteria in our own gut flora microflora as scientists call it | |
43:16 | |
also affect our brains do they play a role in our dietary | |
43:22 | |
korg ireland preferences | |
43:28 | |
john kraham from the university in cork in ireland, the discoverer of | |
43:33 | |
studies of microflora [music] he managed to prove that in mammals | |
43:41 | |
gut bacteria also sometimes influence behavior [music] | |
43:48 | |
he is professor john kraham university core karlandia when we transplant bacteria | |
43:53 | |
highly anxious mice to normal ears, the level of anxiety in these latter increases and vice versa | |
44:00 | |
taking bacteria from calm mice can also reduce stress in anxious mice | |
44:08 | |
[music] scientists are even beginning to understand how these | |
44:14 | |
bacteria interact with neurons | |
44:23 | |
decorate we remove the organs and see the vagus nerve here it is yellow | |
44:31 | |
it is a long nerve connected to all organs and descending into the intestines | |
44:37 | |
allmountain is indeed a key communication path | |
44:43 | |
between our gut and our brain | |
44:48 | |
a few years ago, my Canadian colleagues and I showed, using the example of a mouse, what if we cut | |
44:56 | |
vagus nerve all effects associated with some bacteria disappear | |
45:02 | |
this proves that the vagus nerve is a key link between the gut and the brain | |
45:13 | |
it remains to understand what exactly happens to the brain, we must understand how the signal and | |
45:22 | |
activate areas of the brain that control complex behaviors such as eating behavior | |
45:30 | |
we are working on this now, and so today we need to prove the impact | |
45:37 | |
bacteria on our food preferences, it has already been established that they affect | |
45:42 | |
mood and anxiety, scientists now even consider the microflora as | |
45:47 | |
a kind of intermediary between food and our brain | |
45:53 | |
[music] | |
46:00 | |
the main factor affecting the intestinal flora is the food we eat | |
46:07 | |
dietary diversity is a very important fandom but determines the composition of the microflora | |
46:13 | |
from our birth to our death, we are just beginning to realize the influence | |
46:20 | |
what we eat on the composition of our bacteria, which means how important it is | |
46:27 | |
our nutrition for what happens to our brain our good health depends on | |
46:34 | |
other things and from our microflora the right diet for our mood | |
46:41 | |
it is a diet suitable primarily for the bacteria of our intestines, this led to | |
46:47 | |
the thought of using food to please your brain and take care of | |
46:53 | |
mental health and scientists were seduced by the famous Mediterranean | |
46:58 | |
diet melbourne australia the mediterranean diet is very rich | |
47:05 | |
plant foods a lot of greens a lot of vegetables and fruits other important | |
47:11 | |
elements of legumes such as beans, lentils, and nuts and seeds | |
47:16 | |
fish and of course olive oil olive oil is a very important component | |
47:24 | |
the mediterranean diet we think is a varied diet | |
47:30 | |
contributes to a greater diversity of microflora living in our intestines | |
47:36 | |
the link between this diversity within the gut and good health has become | |
47:41 | |
Ivan's obvious first experience was in the past | |
47:48 | |
year it involved 67 people with severe depression for three months | |
47:54 | |
they received the help of a dietitian and were then reassessed for their symptoms and | |
47:59 | |
made sure that the improvement in the condition is associated with a change in nutrition in those who | |
48:06 | |
adhered to the Mediterranean diet most strictly, the symptoms became less noticeable | |
48:15 | |

48:30 | |
now scientists are exploring all the possibilities | |

traditional Indian medicine has praised spices for centuries and is now in | |
48:42 | |
laboratories are studying their beneficial effects on the psyche | |
48:49 | |
[music] | |
48:56 | |
high hopes are also placed on red fruits and berries | |
49:01 | |
polyphenols that they contain that can invigorate aging neurons | |
49:08 | |
[music] 7 we noticed that when these polyphenols in | |
49:13 | |
In particular, red fruit polyphenols give older mice ways to reduce cognitive decline, that is, in these | |
49:21 | |
animals there is no memory disorder that could be and this brought us | |
49:26 | |
the idea to conduct an experiment on humans recently conducted a study in which | |
49:32 | |
more than 200 people over the age of 65 healthy but naturally | |

49:59 | |
prematurely science and 2 begins to discover the secrets of this sudden connection | |
50:05 | |
between food and brain | |
50:10 | |
the ideal menu for our brain membrane is still largely a mystery | |
50:16 | |
but a varied and balanced diet rejection of the converted | |
50:21 | |
products and sugar in favor of fruits and vegetables by far seems to be the best way to save your | |
50:28 | |
mental ability my grandmother used to say you are what you eat | |
50:36 | |
so eat well and now science proves to what extent | |
50:41 | |
she was right it is likely that in the coming years | |
50:47 | |
will begin to think about individual nutrition and medicine and clearly understand how | |
50:54 | |

if we can’t make up for the nutritional deficit yet, but we know that | |

By focusing on healthy eating, we influence behavior | |

the more we eat chocolate bars, the easier we succumb to temptation and the more | |
