Article on weight gain and exposure too DDT prenatal relates to obesity

 http://goo.gl/CbhI   Long URL below

"Babies born to normal-weight moms who had exhibited elevated blood-DDE
levels (in the upper 25 percent of all participants) were twice as
likely to grow rapidly during their first 6 months than were infants
born to the least-exposed women (with DDE concentrations in the lowest
25 percent). By 14 months old, children whose exposures to DDE in the
womb had been in the top 50 percent were four times as likely to be
overweight ‹ as indicated by a high body-mass-index, or BMI, score ‹
when compared to children with lower exposures.

In fact, a growing body of data has been indicating that some pollutants
‹ known colloquially as obesogens ‹ can trigger the body to put on the
pounds. In animals, these pollutants will sometimes lead a mouse to
become rotund despite eating no more and exercising no less than its
lean cousins.
Many obesogens ‹ including DDE ‹ have a hormonal alter ego. In the body,
DDE can either turn on or block the activity of natural estrogens,
female sex hormones. This pollutant also can block the activity of male
sex hormones. Such properties lead scientists to describe this pesticide
derivative as an endocrine disrupter."

Bill.

The newsgroups that are still going strong follow protocols including
using OT: when topics aren't right on target.

I know I've been slack too but I think we should all adopt the
discipline and make the declaration up front.

 

  I think that the use of DDT is a garden issue.  If you read the
article note that root crops years latter can give  the broken down DDT
to the end user.  Not many of us can claim not using chemicals in the
garden in the past 50 years so I think it is on topic.  I do post off
topic stuff often with the "_OT_"  warning.

    The article you cite is nothing about DDT use, at all, much less
in gardens. It is not science; it is ideological FUD, the speciality
of the organization that publishes "ScienceNews". It is important to
note that DDT is not the only, nor even the major, source of DDE,
which is the toxin under consideration. I suspect the author's direct
references to DDT were for their alarmist value and little else. Face
it, the item you cite was about the apparent coincidence of incipient
obesity within the first two years of the lives of children born to a
vanishingly small proportion of "normal weight" Spanish women -- those
with "elevated" levels of DDE in their blood -- within a statistically
meaningless sample in a "study" that totally to have disregarded any
other variables. As I said, alarmist ideologic propaganda but not
science.
    The citations are of old, outdated references, some as far back
as 1996. The author's own most recent citation of DDT use is from 2000
and it is one of her own articles about the severely restricted and
declining use of DDT for malaria control worldwide. DDT was virtually
banned in North America in 1972 and completely banned in USA and
Canada in early 1980's. Manufacture in Mexico ceased in 1997 and its
use stopped in 2000, two years ahead of target date. It is interesting
that those who most loudly advocate DDT's total elimination from the
planet (among whose number, I count myself) do not live in parts of
the globe where malaria is a persistent public health menace.
    Finally, I submit this quote from your citation:

DDT was

meat

which contains a link to this 2005 article from the same rag and by
the same author:
<http://www.sciencenews.org/view/generic/id/6800/title/Food_for_Thought__Organic_Doesnt_Mean_Free_of_Pesticides>
 which specifically addresses DDE, as well as other pesticide
residues, and from which I quote:

deter her

crops

chemicals

<snip>

peeling all

    Frankly, I would suggest a new OT designation: FUD; or, perhaps,
TiT (Tempest in Teapot). Oh, and I can and do claim absolutely and
unconditionally to not using chemicals in my garden within the past
50+ years.

 Well they don't look too alarmist or shabby to me.

15 year old science is it that old ?

 I stand by the post.
