Chemicals in food may harm children, pediatricians'
group says - FINALLY
!
7-23-2018 By Roni Caryn Rabin, New York Times
A major pediatricians’ group is urging
families to limit the use of plastic food containers, cut down on processed
meat during pregnancy and consume more whole fruits and vegetables rather than
processed food. Such measures would lower children’s exposures to chemicals in
food and food packaging that are tied to health problems such as obesity, the
group says.
The American Academy
of Pediatrics issued the guidelines in a statement and scientific technical
report Monday. The group joins other medical and advocacy groups that have
expressed concern about the growing body of scientific evidence indicating that
certain chemicals that enter foods may interfere with the body’s natural
hormones in ways that may affect long-term growth and development. The pediatricians’ group, which represents
some 67,000 children’s doctors in the country, is also calling for more
rigorous testing and regulation of thousands of chemicals used as food
additives or indirectly added to foods when they are used in manufacturing or
leach from packaging and plastics. Among the chemicals that raised particular
concern are nitrates and nitrites, which are used as preservatives, primarily
in meat products; phthalates, which are used to make plastic packaging; and
bisphenols, used in the lining of metal cans for canned food products. Also of
concern to the pediatricians are perfluoroalkyl chemicals, or PFCs, used in
grease-proof paper and packaging, and perchlorates, an anti-static agent used
in plastic packaging.

“The good news is there
are safe and simple steps people can take right now to limit exposures, and
they don’t have to break the bank,” said Dr. Leonardo Trasande, the lead author
of the statement and chief of the division of environmental pediatrics at New
York University’s School of Medicine.
“Avoiding canned food
is a great way to reduce your bisphenol exposure in general, and avoiding
packaged and processed food is a good way to avoid phthalates exposures,”
Trasande said. He also suggested wrapping foods in wax paper in lieu of plastic
wrap.
Jonathan Corley, a
spokesman for the American Chemistry Council, a trade association, said:
“Chemicals are critical to protecting the quality and integrity of food, help
in the safe transportation and storage of food.” He said that many of the
chemicals referred to in the AAP statement did not act as endocrine disrupters
“in typical uses and at typical exposure levels,” but did not provide
scientific references to support that contention.
In a separate development Monday, scientists
at the Univ. of California, San Francisco, who used a novel method for scanning
blood said they had found dozens of chemicals called environmental organic
acids, or EOAs, in pregnant women.
EOAs, which include
bisphenol-A, have chemical structures similar to hormones, meaning they may
disrupt the endocrine system of the fetus and interfere with development.
Researchers involved in the study, published in the journal Environmental
Health Perspectives, said some of the chemicals had never before been documented
in the blood of pregnant women, including two chemicals that are linked to
genetic defects, fetal damage and cancer.
Among the other chemicals detected in the
pregnant women were an estrogenic compound used in food-related plastic
products, plastic pipes and water bottles, as well as a compound banned for use
as a diet drug by the Food and Drug Administration decades ago because of the
risks but still used in cosmetics, pesticides and as a coloring agent in
industrial processes, said Aolin Wang, one of the study’s authors.
Infants and children are particularly
vulnerable to the effects of chemicals in food in part because they eat more
food per pound of body weight than adults. Perhaps more significantly,
children’s metabolic systems and key organ systems are still developing and
maturing, so hormone disruptions can potentially cause lasting changes.
“Because hormones act
at low concentrations in our blood, it is not surprising that even low-level
exposures to endocrine disrupters can contribute to disease,” said Laura N.
Vandenberg, an assistant professor in the department of environmental health
sciences at the University of Massachusetts-Amherst’s School of Public Health,
who spoke on behalf of the Endocrine Society.
Many of the chemicals
described in the pediatrics report have been shown to interfere with normal
hormone function “by mimicking or blocking the actions of hormones that are
responsible for brain development, development of the sex organs and normal
metabolic functions,” she said.
Child obesity in the
United States has more than tripled since the 1970s, with nearly one in five
children ages 6-19 considered obese; the prevalence of developmental disorders
in children increased from the 1990s to the mid-2000s; and rates of diagnoses of
both Type 1 and Type 2 diabetes among children and teenagers are also on the
rise, according to the Centers for Disease Control and Prevention.
The AAP statement was
particularly critical of a regulatory process by which the FDA designates food
additives “generally recognized as safe,” citing a 2010 Government
Accountability Office review of the program that determined “the FDA is not
able to ensure the safety of existing or new additives through this approval
mechanism.”
An FDA spokeswoman, Megan McSeveney, said the
agency does not comment on specific statements or studies, but said that food
safety “is at the core of the agency’s mission to protect and promote public
health for our nation’s consumers.”
She said FDA regulations define “safety” for
substances in food to mean “there is reasonable scientific certainty that the
substance is not harmful when used as intended,” and that applies to food
additives, color additives and substances that are generally recognized as safe
as well as substances that are used in producing, packing, preparing or
processing food that “are expected to become components of food.”
“If new information
(such as published studies and adverse event reports) suggests that a substance
already in use may be unsafe (whether it is an additive or otherwise exempt),
or if consumption levels have changed in ways that could affect safety, the FDA
can conduct further studies to review whether the use can still be considered
safe,” McSeveney said in an email. The pediatrics group suggests that doctors
recommend families take the following steps in order to reduce chemical
exposures to children:
— Prioritize
the consumption of fresh or frozen fruits and vegetables whenever possible.
— Avoid processed meats, especially during
pregnancy.
— Avoid microwaving food or beverages —
including infant formula and pumped breast milk — in plastic containers, and do
not put plastic food containers in the dishwasher.
— Use alternatives to plastic, like glass or
stainless steel, whenever possible.
— Check the recycling code on the bottom of
products and avoid plastics with recycling codes 3, 6 and 7, which may contain
phthalates, styrene and bisphenols, unless they are labeled “biobased” or
“greenware,” indicating they are made from corn and do not contain bisphenols.
—
Wash hands before handling food and drinks, and wash all fruits and vegetables
that are not peeled.
