With all the talk recently
about GMOs, pesticides, contaminants and heavy metals in our food supply, one
can easily get overwhelmed and left wondering if there is anything in a grocery
store that is still safe to eat. Each week we get emails from Optimal Life
readers asking us what they can do to protect themselves from common unwanted
Poor Food ingredients and most recently we have been touching on the latest GMO
studies. However, due to the recent
articles by Consumer Reports, arsenic
and lead have been topping that query. While we cover this topic more fully in RICH FOOD, POOR
FOOD (release February, 2013) this blog is going to share with you how to
reduce arsenic and lead in some of today’s most common foods by following a few
simple guidelines. While our solutions
won’t always eliminate the arsenic and lead completely, they can help you to
greatly reduce your overall exposure.
Our goal is not to sound the alarms and scare you
away from any of the specific foods we mention in this blog, but rather to give
you a bit more information about the presence possible dangers so that you can
determine your level of exposure. While a small serving of one or two of these
foods may be well within the safe guidelines perhaps, if you over indulge in
one or more of these foods on a regular basis you could be putting yourself
needlessly at risk.
THE JUICE PROBLEM: This past
January we first began hearing about the problems of heavy metals appearing in
bottled juices. According to Consumer
Reports, while the EPA only allows 10 ppb (parts per billion) in our
drinking water, samples from bottled apple juice currently on the market registered
levels up to 13.0 ppb and grape juice samples were even higher registering
levels up to 24.7 ppb. As for lead, one
in four samples had higher levels than the FDA’s bottled water limit of 5
ppb. Some samples actually contained
500% more! This is disturbing because children are some of the largest
consumers of juice and their little bodies are far more susceptible to smaller
quantities of these metals. While the levels are not high enough for acute heavy metal poisoning many studies
have shown that long-term exposure can cause difficulty in language skills,
memory and other brain functions. Additionally, Ana Navas-Acien,
M.D., Ph.D., a physician—epidemiologist at Johns Hopkins University’s Bloomberg
School of Public Health, was the first to suggest, in a 2008 study in the
Journal of the American Medical Association (PDF) that low-level arsenic exposure was associated with the prevalence
of type 2 diabetes in the United States.
THE SOLUTION: Unfortunately, simply choosing 100% organic juice
does not eliminate your family’s exposure to arsenic and lead. While organic
standards prohibit the use of synthetic fertilizers and most pesticides,
organic juices still may contain arsenic if they’re made from fruit grown in
soil where arsenical insecticides had been used in the past. A great tip to
reduce exposure, if you feel that these levels might affect your loved ones, is
to pour half juice and half water rather than 100% juice. Not only will you reduce the amount of
arsenic and lead in each glass, but you will be ingesting less sugar (fructose)
overall, which in turn will cause less of an insulin spike.
THE RICE PROBLEM: Recently,
a November 2012 report by Consumer
Reports stated that arsenic levels in many brands of rice (brown more than
white) as well as popular rice products like baby formula, rice pastas, rice
syrups, and rice-based cereals are at worrisome and potentially dangerous
levels. With so many people now choosing gluten-free foods, rice consumption
has increased, and with it, exposure to both inorganic arsenic (a carcinogen)
and organic arsenic (less toxic, but still a concern). For more of a discussion
on the benefits of white vs. brown rice and some of the pros and cons to each
you can check out Chris Kresser’s blog on this topic here.
THE SOLUTION: To
reduce your exposure scientists at Consumer
Reports recommend restricting rice and rice-based hot cereal, ready-to-eat
cereal, rice pasta, and rice cakes to two to three servings a week for adults,
and one to one-and-a half servings a week for children. And proper preparation
of rice can aid in limiting exposure. Thoroughly
rinsing and cooking your rice with six cups of water to one cup of rice and then draining the
excess water is one way to reduce this harmful carcinogen. While this will lead to higher levels of
micronutrient loss than conventional
methods, it can reduce inorganic arsenic content by
about 30 percent. Additionally, purchasing foreign rice can be a safeguard,
because according to the Institute of Agriculture and Trade Policy “American- grown rice contains 1.4 to 5 times more arsenic on average than
does rice from Europe, India and Bangladesh— scientists think the likely
culprit is the American practice of growing rice on former cotton fields
contaminated with long-banned arsenic pesticides.”
THE BACON (CURED MEATS) PROBLEM: Last week
we reported that we felt while others in the industry discussed the safety of
nitrates in cured meats, many were overlooking the problem of heavy metals in
this synthetic additive. You can read the entire blog here. We first
dispelled the myth that nitrates, either from sodium nitrate or from celery
salt, caused cancer because absent a nitrosamine precursor, no cancer-causing
properties are evident. However, we also discovered that The Food
Chemical Codex allows for up to 10,000 ppb (parts-per-billion) of lead and
3,000 ppb of arsenic to be present in synthetic sodium nitrate. Remember,
the levels for drinking water, at which these chemicals present a serious
health risk, set forth by the EPA are 15 ppb and 10 ppb, respectively.
This means that the "acceptable levels" to be found as a residue in
sodium nitrate are roughly 667x and 300x the levels recognized as deleterious
to human health, again respectively.
We would like to add,
that this is should not be of
concern to those who only eat bacon on occasion, or limit their bacon slices to
one or two slices per day. However, with
whole cookbooks and TV shows now on the subject of bacon, and many Paleo cookboods
including bacon in one form or another as an ingredient in most every recipe, we
felt it was worth a mention. Here’s the reasoning. While it is true that the “acceptable levels”
in sodium nitrate residue are too high, if you take into account how little is
added into the bacon itself your risk becomes much smaller. In fact, not a real concern at all. However, for those who eat bacon by the
pound, purchase cured sandwich meats and enjoy hot dogs on a regular basis,
this sodium nitrate becomes a reoccurring ingredient we feel is completely,
unnecessarily opening the door to unacceptable levels of arsenic and lead
exposure.
Additionally, after
reading thousands upon thousands of labels as part of the research for RICH
FOOD, POOR FOOD, we have become acutely aware that those companies who are
removing the synthetic nitrates and replacing them with celery and sea salt,
are also more aware as to the quality of the other ingredients in their
products. That is because when companies realize that consumers are searching
for better, healthier products, they begin to revise their recipes and luckily,
the improvements in ingredient quality are often across the board. In this way, removing synthetic nitrates from
the approved ingredients list on the products you purchase also helps to limit
your exposure to other POOR FOOD ingredients that all too often come hand in
hand, such as BHT, BHA, dextrose, modified food starch, added sugars and HFCS.
THE SOLUTION: Due to bacon’s high micronutrient content, and
the fact that it’s plain old delicious, we don’t suggest you put aside this
pork product. We do however, recommend
that you choose products, such as bacon, sandwich meats, and hot dogs, cured
with celery or sea salt to limit heavy metal exposure. While there may not be a
huge amount of lead and arsenic in each bite, because so little is used in the
curing process, why take any risk at all?
And again, this is especially true for those of you who eat bacon,
sandwich meats and/or hot dogs on a daily basis.
THE POULTRY PROBLEM: Here is a
little bit of info from Rich Food, Poor
Food on this topic:
“According to the FDA,
poultry farmers are permitted to feed arsenic, a recognized carcinogen to birds,
for “growth promotion, feed efficiency, and improved pigmentation.” The arsenic
affects the blood vessels in chickens and turkeys, causing them to appear
pinker and therefore fresher. When the Minnesota-based advocacy group Institute
for Agriculture and Trade Policy tested conventional poultry, it found the
poison (arsenic) in 55 percent of chicken parts (breast, thighs, and livers)
tested, with the highest amount--21.2 parts per million--occurring in generic brands. If you want to know how safe
that is, you should know that the EPA considers 10 parts per billion in
drinking water to be high enough to pose a cancer risk. The chickens tested had
up to 2,000 times more of these
cancer causing arsenic levels! The European Union has outlawed the use of arsenic
since 1999, and you should ban it from your body by choosing organic birds.”
THE SOLUTION: Choose Organic Poultry! This one is an easy fix,
folks. Buying USDA-certified organic chicken is a great solution, since
producers using this label are legally prohibited from using arsenic. Not only
is there no arsenic in the chicken feed, but you are also guaranteed that the
birds must be fed 100 percent organic,
non-GMO feed that contains no animal byproducts. It also must be free of
pesticide, chemical fertilizers, hormones, and antibiotics, and the birds must
receive outdoor access (but no duration or location requirements are indicated).
Better yet, purchase ‘pastured’ poultry (from a farm that follows the organic
guidelines) and serve up a far more micronutrient RICH chicken in your kitchen.
So, what is the take-away here? We want
to be clear, we aren’t asking anyone to sound an alarm, or run through the
streets scared away from the rice served along side their Chinese stir
fry. The intent of our message is
awareness, simply offering you information you can use to make the smartest
choices based on your dietary philosophies. The fixes we offer are pretty easy,
and if you feel you might be better off eliminating some of the risk, well… you
now have the tools. Throughout the next few months we will be sharing great
shopping, safety and food preparation tips with you that increase the
micronutrient value of your foods while making them safer through the
elimination of over 150 POOR FOOD ingredients that we have identified. No one
is perfect, and we can’t expect to live a life where none of these POOR FOOD ingredients
creep in every now and again. However,
by simply buying products that eliminate these possibly hazardous add-ins you
are sending a message to the stores and the manufacturers that food safety and
high quality ingredients are important to you. Together we can make a
difference. Until next time…Healthy Shopping!
