Nutrición hecha a la medida de tus genes y microbios | Daniel Ramon | TEDxCiutatVellaDeValencia


in 1961 a scientist from

surname fucker discovered some rats

that unlike this one you see here

it did not weigh between 200 and 300 grams weighed

around 800 900 grams

it was a rat with a morbid obesity

in later years and thanks to all

a series of investigations

determined that those rats had that

over weight

simply because they had a mutation

in a gene a gene that encodes something very

important the hormone that satisfies us that

hormone is called leptin and when not

it works correctly we did not make

we eat we eat we eat and we get fat

an exaggerated form

that’s what happened to those rats

we have proven in humans there is the

same mutation and when it appears

it also results in super individuals

obese unless unless they follow a

proper diet a certain treatment

therapeutic and a lifestyle

healthy

this is a good example as after

understand the genetic basis of a

problem can be given a solution

food is an example of how

food and genetics go together

but actually food and

genetic much more units than what

can you imagine

you know that everything we eat is

an animal is a vegetable or is a substrate

animal or vegetable fermented by

microorganisms by bacteria like the

yogurt that a tomato has an aroma

determined or that in an animal there is

in his more or less fat paw goes to

depend fundamentally on your genes and

of how we feed it in the field as

Let’s grow that tomato in the field

as well

but wine could be a good example

again of how food and

genetics go together you know that the

wines has a series of components

important can have better color

can have better aroma or better body

at the end of which you rely for that

depend on the genes of the

grape area which has been done is

came and with the yeast genes that

I have fermented it and of course with the

winery and how he has worked but the

will be the origin of the entire fund

genes in that for example in the genome of

that grape and genes that code

anthocyanins that give a red color or genes

that encode terpenes that do not give a

fruity aroma and that those genes of the

yeast are able to produce some

enzymes that release those components and

do not think that that is left alone

A) Yes

you know there are hunters who have a

special power to detect the aroma of

the wines in many cases these

collectors although they do not know they have

trained very well but they have a background

important genetic and have been made

studies that show that some

wine tasters have mutations by

example in genes that encode the

olfactory receptors and that’s why they’re so

sensitive to the aroma of all this

will reduce six it is important to know

the genes and the total genes that is

the genome of an individual to do that

what we do is read the genes

genes are constituted by a

molecule that is called adn and if

you remember from the school this molecule

they have only 44 letters four

components adelina cytosine guarín and

thymine and we would have it like acg

vote that we have brown eyes or

have a predisposition to lose the

hair as is my case is written in

our genes

It is therefore important to know the reading and

know how to read the genes we call it

sequence when we sequence the genome

of an individual and showed their genes

we can find errors and those errors

are the mutations

what happens is that this genes ehlers not

it’s easy they started to be able to read

the seventies where a

American laboratory and laboratory

English developed the first

techniques that were very expensive and that

they got that they will start

sequence genes and that was pretty

well but it cost a lot until in a

particular moment I ‘m talking about

does nothing of the year

min 1 was able to sequence something

incredible for all the genes of

genome of a human individual

in mid-2001 both a group

American public to the consortium for

sequencing of the human genome like

a private company celera genomics

they published with a day of difference to

the first two genome drafts

human were able with those techniques

primitives that I told you to sequence

our entire genome and they discovered that

humans are 24 thousand genes

interacting with our environment

environment of those interaction genes comes out

as it used to say the color of our

eyes or it comes out that we have a

predisposition to bald or out

for example that we have nothing is possible

predisposition to develop cancer

of colon or a breast cancer and these

latest applications these applications

with medicines were those that gave

place to the need for sequence of

first human genome we sequence more and

if possible if we coincide thousands and

thousands and thousands and if possible sequence

of the genomes of all humans

because it’s going to be a tool that

will allow to predict diseases already to

attack them with time

that was not easy, we had to start

develop it is speaking the

last 15 years of a series of

machines that we call platform

massive sequencing that allow

sequence the genomes much more

fast and much cheaper because

you know, sequencing is the first genome

human

It cost a lot to cost the work of 3,000

scientists from those two institutions

that I told you about for ten years and the

It was cost 3 billion

nowadays the companies where we manage

the public laboratories are

genomic sequencing platforms

massive

we are able to sequence a genome

human in only three weeks for about

6,000 euros and can be a technician

of fp

only 15 years have passed is a

revolution we think many

citizens are not aware and the

promises that in just two or three years

more we will be able to sequence

a human genome with new technologies

in about ten minutes and for about 200

Dollars

this will make the whole world sequence

its genome

and that can have a positive part

but also a negative part

imagine that the insurance companies

probably tell us before we have

a life insurance go sequence your

genome and see it I will tell you how much I

you have to pay

but let’s go back to what we were

speaking before how this impacts

our life when sequenced genomes

humans and to date of today sequenced

thousands of them we have seen that there is no

two playable genomes

there is something much more interesting too

we have sequenced the genomes of everything

that we eat and in these moments the

food technologists

we have a lot of molecular data

as we do not ask or think where they should

of being written all the

physical and chemical characteristics

organoleptic and nutritional

that we eat and there is still more

these techniques can be applied to

look for bacteria this is something that to me

I’m very interested in the microbiologist

origin and before to see in a

determined sample how many bacteria

there was no choice but that or

they look at the microscope or sow in a

plate and expect it to grow and but I was

gave a very poor idea of ​​what was

just 10%

nowadays using the techniques of

Massive genomic sequencing

we have seen that everywhere there is

thousands and thousands of microorganisms

we have done a job with classmates

from valencia university we have seen

that solar panels

look at the solar panels that

it seems to be an inhospitable place where

do not go see anything with the panels

of the valencia university and

More than 500 bacterial species

different and if we look inside of

our body

that maxim of medicine that

said a healthy person can not have

bacteria inside your body because if

does not have an infection is a lie in a

healthy guy like you in your

lungs there are more than 600 species

different bacteria in your skin

more than a thousand in the vagina a healthy woman

more than two hundred and where there is more

it is in our digestive tract where there is

more than a thousand bacterial species

different and this has to do again

with food because the role of

all those bacteria in the tract

digestive is to digest what we eat and if

there is not a good component of those

bad bacteria is going to go

why do not you understand better if you weigh 70

kilos

two of your 70 kilos are not

you are the bacteria that live

within your body and what we have

seen and it’s fascinating is that there are not two

more digestive microbe same in

our laboratory to date of today

We have sequenced more than 35,000

microbiomes we have not found two

individuals with the same microbiomes

how it happened with the genes

there is an individualization of our

genome and our microbiome that is

as we call this set of

microorganisms and what is more

fascinating we have found that by

example people who have celiac disease have

changes in those microbiomes if they appear

ups and downs of certain

species or people who have diabetes or

people who are obese and most

interesting of all is that with the

adequate nutrition intervention

for example in the case of the obese

following a hypocaloric regime in

little time can recover the weight

normal and that coupled with a rebalancing of

those changes in the microbe there is something

more interesting and is that we have

found that there are changes in the

digestive microbiome that has to do

with a behavior for example

appear changes in autistic appear

changes in people who have episodes of

stress or even changes appear in

people who have headaches and that brings us

to investigate to look for microorganisms

solutions that reverse those changes and

in that we actively work my

laboratory you can think of a diet

with certain probiotics sos

cuétara has lived bacteria

Lactobacilli or certain prebiotics

that reverses in that situation and kurt in

the problem and all this brings us to what

what we call personalized nutrition the

personalized nutrition is nothing more than

understand what genes there is a certain

individual and what microorganisms for

packaging or designing you nobody is at

letter I speak not science fiction anymore

is in the market

in the united states there are many companies

that offer the possibility of online

of sequencing your genome or sequencing

your microbiome and based on that and with a

nutritional questionnaire

a diet guideline and do not think that

except that you are not interested in the company

a company as a change the

that you know is the biggest leader in the

world in soups sales has invested 32

million dollars six months ago in

one of these companies that sequence

genomes on the internet and even a

company like Nestlé has created a

research center on the outskirts

of the suns just to study the

relationship between genomics feeding

Alzheimer’s cancer comes to us all

authentic revolution in the next

years will be based on this nutritious

a personalized and that will change

radically for example the profile of

technicians who work in companies

food

we will need in the companies

food experts who understand

bioinformatics experts who understand

of big data even companies

will have to do very

probably alliances in benthos with

google internet world companies

has invested in one of these companies

of massive genomic sequencing or ibm

is active at this time in

develop computer programs

for the massive sequencing we were

awaits a revealing future in the

last years of work in the group in

the one who worked

we have spent time trying

understand how the microbiome is and how

is the genome of for example males that

they have infertility problems and we have

found a treatment with some

certain bacteria can increase

the human sperm emotion or

we have seen in collaboration with the

Valencian Infertility Institute

like the digestive microbiome of a

pregnant woman varies throughout the

pregnancy and the last three months without

an absolutely aberrant microbe

similar to a patient with type 2 diabetes

but it is the one that has to have because

those bacteria are able to extract the

maximum energy of what you eat

are the months in which the most grows

fetus or then the child is born and we have

developed probiotics that are

able to inhibit the replication of

gastrointestinal virus or reverse

episodes of dermatitis that are very

frequent in newly-born children

if there are any doubt, a future

hopeful for nutrition

personalized and feeding

thank you very much

[Applause]
