"Is Organic Meat Less Carcinogenic?"
"Flashback Friday: ¿Es menos carcinógena la carne ecológica?"
This study, on the carcinogenic risks
Este estudio, sobre los riesgos cancerígenos
associated with the intake of various meats,
asociados con el consumo de distintas carnes,
estimated the risk was so great that
estimó que el riesgo era tan grande que
we may not want to feed beef, pork,

carne de res, puerco o pollo por más de
5 times a month.
5 veces al mes.
This was in Europe, where lamb contamination
Esto sucedió en Europa, donde la contaminación de carne de cordero
is a particular problem.
ya es un problema en particular.
In the United States, if there was any standout
En Estados Unidos, si hubiera algo que destacar
it would be chicken and PBDEs,
sería el pollo y los PBDE,

que son los químicos retardantes de llama,
not only compared to other meats,
y no solo comparado con otras carnes,
but other countries.
sino comparado con otros países.
U.S. chickens are like 10-20 times more
Los pollos de Estados Unidos que han sido puestos a prueba están entre 10 a 20 veces más
contaminated than samples taken from

other countries that have been tested,

though diet is not the only source of exposure,

than those eating meat,
que aquellos que comían carne,
though a large proportion of that

may be from chicken.
en omnívoros podrían provenir del pollo.
For other chemicals, diet may play a larger role.
En relación con otros químicos, la dieta puede desempeñar un papel aún mayor.
Studies of the pollutants in the breast milk
En estudios de hace más de 30 años
of vegetarians dating back over 30 years
sobre los contaminantes en la leche materna de vegetarianas
have found the average vegetarian levels
se ha encontrado que los niveles de algunos contaminantes del vegetariano promedio
of some pollutants were only 1 to 2 per cent
fueron solo del 1% al 2%
as high as the national average.
del promedio nacional.
In fact, for the 6 out of 7 pollutants
De hecho, 6 de cada 7 contaminantes
they looked at, there wasn’t even overlap
que fueron evaluados, ni siquiera se superpusieron
in the range of scores;
en el rango de puntajes;
the highest vegetarian value was lower
el valor vegetariano más alto fue menor
than the lowest value obtained

in the general population.

This is presumed to be because these pollutants

concentrate up the food chain;
se concentran a lo largo de la cadena alimenticia,
so, by eating lots from all the way down
entonces, al consumir muchos alimentos de la parte más baja
the food chain, plants, those eating

For example, dioxins: meat, fish, and dairy
Por ejemplo, las dioxinas. Se cree que la carne, el pescado y los lácteos
believed to contribute almost all
contribuyen a casi la totalidad
of the dioxin body exposure.
de la exposición corporal a las dioxinas.
And, indeed, if you look at those

they may only have about a third of

or even less than a fifth circulating

This study really struck me.
Este estudio realmente me impactó.
India has been facing a major problem
Cada año, India ha venido afrontando un gran problema
of treating its millions of pounds
en el tratamiento de sus millones de kilos
of electronic waste every year.

And, these poor workers at these electronic

waste recycling plants can be exposed

to high levels of toxic chemicals,
a altos niveles de químicos tóxicos,
ending up with this kind of concentration

of PCBs in their bloodstream,
de PCB en su torrente sanguíneo,
twice as high as those living
que es casi el doble de la de aquellos que viven
about 250 miles away along the coast.
a unos 76 metros a lo largo de la costa.
But these were non-vegetarian
Pero estos trabajadores de la planta de desechos
workers at the waste plant.
no eran vegetarianos.
The PCB levels of the vegetarians

was even lower.
fueron mucho menores.
The problem with these
El problema con estos
cross-sectional studies
estudios transversales
is that we can’t single out the diet.
es que no podemos individualizar su dieta.
Maybe vegetarians have other lifestyle
Quizá los vegetarianos tienen otros comportamientos de estilo de vida
behaviors that protect them.
que los protegen.
You don’t know until you...
No se puede saber, hasta que...
put it to the test.
se pone a prueba.
Change people’s diets and see what happens.
Hay que cambiar la dieta de las personas y ver qué pasa.
That’s hard to do with persistent pollutants
Eso es difícil de hacer con contaminantes persistentes
like PCBs which may take literally decades
como el PCB, el cual podría tardar literalmente décadas
to detoxify from the body,
en desintoxicarse de nuestro organismo,
but we can get rid of heavy metals
sin embargo, nos podemos deshacer de metales pesados
like mercury in a matter of months.
como el mercurio en cuestión de meses.
And, indeed, within 3 months of the

exclusion of meat, poultry, fish, and eggs

from their diets, there was a significant
de sus dietas, hubo una disminución significativa
drop in the levels of toxic heavy metals
en los niveles de metales pesados tóxicos en sus cuerpos,
in their bodies, including mercury,
incluidos mercurio,
cadmium, and lead.
cadmio y plomo.
Up to about a 30% drop within 3 months.
Una disminución de hasta 30% en 3 meses.
What if we just stick to organic meat?
¿Qué pasaría si solo se consumiera carne orgánica?
Certified organic meat comes from
Por ley, la carne orgánica certificada
livestock that are fed with organically
es de ganado que se alimenta con comida
produced feed that is free of pesticides
producida orgánicamente, libre de pesticidas
and animal by-products, by law.
y subproductos animales.
Therefore, one would assume that there

should be a lower accumulation

of chemical residues.
de residuos químicos.
However, on a practical level,
Sin embargo, a nivel práctico,
there were simply no studies on the
no había estudios sobre el
chemical residue content in organic meat, until...
contenido de residuos químicos en la carne orgánica, hasta...
now.
ahora.
Researchers acquired 76 samples
Los investigadores obtuvieron 76 muestras
of different kinds of meat,
de diferentes tipos de carne,
both organic and conventional,
tanto orgánica como convencional,
and quantified their levels of contamination
y midieron sus niveles de contaminación
with 33 different carcinogenic
en base a 33 carcinógenos distintos
persistent organic pollutants.
(contaminantes orgánicos persistentes).
After all, the ingestion of food
Después de todo, la ingesta de alimentos
contributes more than 90% to the
contribuye en más del 90%
total current exposure to these compounds,
de la exposición a estos compuestos,
especially food from animal origin.
especialmente los alimentos de origen animal.
On the other hand, an increasing number
Por otro lado, cada vez más consumidores
of consumers are choosing organic.
están eligiendo productos orgánicos.
In fact, organic food production increased
De hecho, la producción de alimentos orgánicos aumentó
like 50% during the last decade;
en un 50 % durante la última década.
so, are consumers of organic meat protected or not?
Entonces ¿los consumidores de carne orgánica están protegidos o no?
Well, “no sample was completely free
Pues, “ninguna muestra estuvo completamente libre
of carcinogenic contaminants,”
de contaminantes cancerígenos”,
which is to be expected given how polluted
lo cual es de esperarse dado lo contaminado
our world is these days, but what was
que está nuestro planeta actualmente, pero lo
surprising was that “the differences between
sorprendente fue que "las diferencias entre la carne
organically and conventionally produced

meats were minimal.”
fueron mínimas".
Furthermore, the current pattern of
Más aún, el patrón actual de
meat consumption exceeded
consumo de carne excedió
the maximum limits either way.
los límites máximos.
Strikingly, the consumption of organically
Sorprendentemente, el consumo de carne producida orgánicamente
produced meat not only doesn’t appear
no solo parece
to diminish this carcinogenic risk,
no disminuir el riesgo de cáncer,
but was sometimes found to be even higher.
sino que a veces el riesgo fue incluso mayor.
Bottom line, sadly, is that the consumption
Lamentablemente la conclusión es que
of organic meat does not diminish the

carcinogenic potential associated with

the intake of these pollutants.
