when at home we have to save
some substance that is potentially
toxic
I mean an insecticide or some
product with the aim of finding
some plague we take some
precautions
or we do it in a warehouse on a fourth
paragraph or in a moment if it is
possible the highest and the labeled and
far from the reach of the boys
however, what happens if I tell you that
all of us without realizing
Also without exception since
a lot of time
we keep a substance potentially
risky to health in our kitchen
that this substance is much more dangerous
for pregnant women and for boys
that in addition those invisible substances
our eyes
we take them and we bring many times
our jobs and we put it in
contact with our food and that
that substance that some still
probably do not know is called
bisphenol to efe nora is a chemical
petroleum derivatives with which
manufacture hard plastics of the type
the polycarbonate Polycarbonates
bisphenol in particular is the one that
confers hardness and transparency and is with
the one that mostly many objects
plastics are manufactured and many of
which we use to store and
keep food in the kitchen not
it’s the only place where we find the
ife not also in the pickets
supermarket in the ink of the tickets
of supermarket in the coating
inside of the cans of food that
are painted or home, let’s say
covered by a movie to avoid
its corruption also in containers in the
dental shelves in the bottles in
deferred ce binds weakly to
plastic so with the action of
heat and the detergents with which the
come on these utensils comes off
of plastic and goes to the food when
we heat for example to the microwave or
another or with another and another form the
foods that are contained in
Containers that contain our bisphenol
food is contaminated and when
we consume we think about our organism
once it is within our
organism has the particularity of
behaving like an impostor imitates the
action of a hormone mimics the action of
Estrogens Estrogens are
hormones that fan are manufactured normally
the ovaries to a lesser extent in the
testicles and not after the null as the
adrenal glands are not suits
we are hormones related to
reproduction
and they are very important and necessary and
responsible for biological mechanisms
very sensitive more than one is thinking
at this time that a substance
chemistry capable of mimicking the
estrogens limit their action and their
effects can alter the function
breeding and this is shown by the
experiments with the team with the group
of research the one that integrated
we work designing experiments in
animal models trying to understand from
know what those effects are and what
are the consequences on health
reproductive we know so far of the
bisphenol a
we know that he is capable
first is one of the teams
considered environmental pollutant more
studied in the world that we know
we know that it does not behave like a
toxic traditional
we all know that a toxic or so
less the paradigm is that the toxic to
higher dose greater effect
However, in my faith, I do not know
behaves like this is a toxic capable of
act at very small doses measured in
parts per million in that too
they look like hormones
control agencies have established
for phenol a dose that they consider
considers the control bodies
sure that it is a safe dose is
that daily dose of exposure in the
that should not cause disorders
however in our experiments there
we work exposing ewes in the
first days of life and we study them
later we find alterations in
ovarian function not only
exposing them to 2 and safe but at doses
a hundred times lower than the other ensures
what we know about phenol is that part
of a group of chemicals that its effect
He exercises a lot of time later
away from the time of exposure and
when I say later I mean that a
exposure during pregnancy or little
after birth at doses of
bisphenol to this chemical produces its
effects weeks months years and decades
later away from the moment of
exhibition that what is happening well
as estrogens normally program
the reproductive organs so that in the
adult life will work conveniently
adequate and appropriately
Phenol interference can do what
what we call a reprogramming of those
organs and then later in the
adult life
that body does not efficiently comply with
its function for which it was designed or
sick to say there is evidence
growing and solid relationship to
effects that it produces in the models
animals in animals and studying in
effect on related bodies
with the reproduction
For example, he enumerated the alterations that
produces later in adult life
acquire or produce failures in
implantation of the embryo
in the case of the breast and the prostate
have been reproduced in animals of
laboratory precancerous lesions by
effect of exposure to bisphenol a in
the testicle produces a decrease and
a faith
lack of quality on the cross none
extinction in the number and a decrease
also the sperm quality and in the
ovaries as I told you we know that
obviously produces an alteration that
could compromise future fertility
of that female in the case of animals
and probably the woman but good
all this is in animals that we know of
its effect on humans of beings
humans it has detected bisphenol A
in urine in blood and fluid
amniotic that surrounds the fetus and alberche
with which you are telling us is
able to cross the barrier
placental and pass object and also that
a woman who has been exposed to mij
enol also has possibilities not only
from passing it through the milk to your
nursing child but also that he has
possibilities of accumulating it in
fabrics and facing a demand as is
breastfeeding mobilize it and pass it to
baby
all these data are giving us a
an overview of the effects that
could produce our species on base
to trials that have been conducted in
animals very well what can we do
in principle I think that what is more
important is to inform us well
informed of from information
reliable and spread that information
that serves and has served for example to
that first canada based on studies
also made in Argentina that
they collaborated to take this
prohibition determination was the first
country banned baby bottles
plastic
then did the united states the union
European and finally Argentina the year
2012 with the intention
of this mini sar the risks that could
produce we review the passage of my
practices mom’s phenol to
baby but there are other things that we can
do
First do not combine heat with plastic and
food as far as possible not
heat in force not our microwave
food contained in packaging
plastics where possible also use
or some other ceramic alternative
metal glass or simply dump from
the one from the plastic container to a plate
that is not plastic to be able
warm it too a recommendation if
someone works as a cashier in a
supermarket use gloves for
avoid exposure to the ink of the
tickets
there are studies that indicate that those
people who work in this activity
have higher levels of phenol in
blood
there are also studies done in centers
of fertility where they have noticed that
those women who are infertile
have higher levels of bisphenol
a blood very well what we can do
also like life and options
one can take into account this
information can ignore it or it can
be aware and take some
precautionary measures such as those
we comment to minimize the risks of
exposure to bisphenol and in that case
also one of the things that we can
to do is to know what we are
buying know what we are using
and if we are going to use plastic containers
use those that are defense and
origin of its manufacture
assure us that they are free of phenol
there is in the market
one should use that yes it is
decided to use the plastic like all the
life as many things in life
we can just worry
to occupy ourselves with the decision will be in each one
of us
