Research has shown that pesticides and other agricultural
chemicals are neurotoxins and can cause disruptions to your
neurological system and your brain. The reason why neurotoxins
still enjoy widespread use on our fresh food supply is really
more about the bottom line for farming operations than it is
about the science of human health.
The Environmental Protection Agency (EPA) considers 60
percent of herbicides, 90 percent of fungicides, and 30 percent
of insecticides to be carcinogenic. All of these toxins are
permitted on conventional farms, and any number of them can end
up on your plate when you purchase conventionally-grown fruits
and vegetables.
The increased use of genetically engineered Bt hybrid plants1
and soil insecticides also increases the chemical load in food —
particularly processed foods.
These man-made neurotoxic chemicals can bioaccumulate in your
body, as they resist breaking down in water and also accumulate
and store in fat, where they can remain for long periods of
time.
In short, this means your body has a very hard time getting
rid of them once they enter your body. The answer, of course, is
to limit your exposure as much as possible, giving your body a
chance to eliminate the toxins you do inadvertently ingest. One
food that can help with
detoxification is fermented foods.
Updated Shopper’s Guide to Pesticides in Produce
Your best bet is to buy only organic fruits and vegetables,
as synthetic agricultural chemicals are not permissible under
the USDA organic rules. That said, not all conventionally grown
fruits and vegetables are subjected to the same amount of
pesticide load.
And with food prices rising, many are looking for ways to buy
the healthiest foods possible at the lowest cost.
One such way would be to focus on purchasing certain organic
items, while “settling” for others that are
conventionally-grown. To do this, I recommend familiarizing
yourself with the Environmental Working Group’s (EWG’s) annual
Shoppers' Guide to Pesticides in Produce.2
Of the 48 different fruit and vegetable categories tested by
the EWG for the 2013 guide, the following 15 fruits and
vegetables had the highest pesticide load, making them
the most important to buy or grow organically:
|
Apples |
Celery |
Cherry tomatoes |
|
Cucumbers |
Grapes |
Hot peppers |
|
Nectarines (imported) |
Peaches |
Potatoes |
|
Spinach |
Strawberries |
Sweet bell peppers |
|
Kale |
Collard greens |
Summer squash |
In contrast, the following foods were found to have the
lowest residual pesticide load, making them the safest bet
among conventionally grown vegetables. Note that a small amount
of sweet corn and most Hawaiian papaya, although low in
pesticides, are genetically engineered (GE). If you’re unsure of
whether the sweet corn or papaya is GE, I’d recommend opting for
organic varieties:
|
Asparagus |
Avocado |
Cabbage |
|
Cantaloupe |
Sweet corn (non-GMO) |
Eggplant |
|
Grapefruit |
Kiwi |
Mango |
|
Mushrooms |
Onions |
Papayas (non-GMO. Most Hawaiian papaya is GMO) |
|
Pineapple |
Sweet peas (frozen) |
Sweet potatoes |
What to Look Out for in the Meat Isle
Many people are still in the dark about the vast differences
between
Concentrated Animal Feeding Operations (CAFOs) and
organically-raised, grass-fed or pastured meats, both in terms
of contamination and nutrient content. It's important to
understand that when you raise animals in a CAFO — away from the
animals’ natural environments and diets — you dramatically
increase the risk of pathogenic contamination that can make you
ill.
Take beef, for example. Most CAFO cows are fed grains
(typically genetically engineered grains, which make matters
even worse), when their natural diet is plain grass.
Grain diets create a much higher level of acidity in the
animal's stomach, which E. coli bacteria need to survive.
Meanwhile, E. coli contamination is actually quite rare in
organic beef for this reason — the cows just aren't susceptible
to those kinds of disease-causing bacteria and viruses when they
eat what they were designed to eat.
Also beware that bacterial contamination of
meat-glued steak — a cost-saving scam that is far more
common than you might think — is hundreds of times higher than a
solid piece of steak; therefore, if you cook your steak rare,
which is ordinarily the most healthful way to cook your meat,
you're at a much greater risk of contracting food poisoning.
You'd think that since the meat is being raised in ways that
are known to encourage disease-causing organisms, there'd be
stringent requirements on testing. Unfortunately, that's not the
case. For example, there is no federal requirement for meat
grinders to test their ingredients for
E.coli prior to selling them. And most retailers do not test
either. In August 2008, the USDA issued a guideline urging meat
processors to test their ingredients before grinding. But the
guideline is only optional and has been met with criticism and
resistance from the meat industry.
Want Safer Meat? Buy Organic Pastured/Grass-Fed
It’s no surprise then to discover that pathogenic
contamination of meat products is quite high. What’s worse, the
routine use of low-dose antibiotics in CAFO’s has led to a
dramatic and rapidly rising presence of antibiotic-resistant
pathogens.
According to a recent NPR report,3
data published by a joint government program4
from tests conducted on supermarket meat samples collected in
2011 by the National Antimicrobial Resistance Monitoring System,
reveals the presence of several disease-causing bacteria,
including the super-hardy antibiotic-resistant versions of
salmonella, Campylobacterand E. coli. After
analyzing the data, the Environmental Working Group (EWG)
highlighted some of the startling implications in its own
report,5
aptly named “Superbugs Invade American Supermarkets.” The EWG
points out that many of the meats tested contained “startlingly
high levels” of antibiotic-resistant bacteria on:
- 81 percent of ground turkey
- 69 percent of pork chops
- 55 percent of ground beef
- 39 percent of chicken breasts, wings and thighs
One of the best ways to avoid contaminated meat is to avoid
meat from animals raised in confined animal feeding operations
(CAFO’s), aka “factory farms,” and buying organic, pastured or
grass-fed meats instead. Growth promoters such as antibiotics
are not permitted in organic animal farming, and
organically-raised animals are also healthier as a result of
being pastured, so overall you’re getting far “cleaner,”
healthier meat.
“To be safe, consumers should treat all meat as if it
may be contaminated, mainly by cooking thoroughly and using
safe shopping and kitchen practices (see EWG's downloadable
Tips to Avoiding Superbugs in Meat),”6
EWG suggests.7
Beware of Pesticides in Chinese Imports, Study Warns
Another related study warns about the pesticide load found in
produce imported from China. The analysis was done by Food
Sentry, an American food inspection analyst. After analyzing
close to 1,000 reported food violations spanning 73 countries,
China was identified as having the most violations. A second
study focused on the Chinese violations only, over a 15-month
period. As reported by Food Navigator,8
pesticides were the number one complaint. Thirty-two pesticides
were identified in Chinese fresh produce and spices, in excess
of the permissible amounts. Chinese seafood was also found to be
high in antibiotics and other drugs. Other chemicals found in
levels exceeding allowable amounts in food included:
- Sulfur dioxide
- Sulfites
- Formaldehyde
- Coloring dyes
- Sodium saccharine
The most concerning chemical was sodium hydroxide, aka
caustic soda or lye, found in dairy. Excessive lead levels were
also found in kelp and cardamom, and infant formula was found to
contain excessive levels of mercury. According to Food
Navigator:
“The study also found that economically motivated
adulteration — the intentional adulteration of a food for
economic gain — continues to be an issue in China. Examples
of this included counterfeit eggs that were man-made from
various substances and chemicals, synthetic shark fin,
synthetic abalone and counterfeit peanut oil made from other
oils.”
USDA Ruffles Feathers with New Poultry Inspection Policy
While all manner of food fraud and contamination issues
continue to rise, the White House administration is about to
dramatically scale back the US Department of
Agriculture’s (USDA) oversight of chicken- and turkey
slaughterhouses. As reported by Mother Jones:9
“Currently, each factory-scale slaughterhouse has
four USDA inspectors overseeing kill lines churning out up
to 140 birds every minute. Under the
USDA's new plan, a single federal inspector would
oversee lines killing as many as 175 birds per minute. That
would mean there are three fewer inspectors for a production
line running 25 percent faster...
[O]n April 10, the administration released a
prospective USDA budget indicating that the agency plans
to implement the new rules by September 2014. And in
testimony before the House Appropriations Subcommittee
on Agriculture on April 16, Vilsack said the rules would be
finalized 'very soon,' declaring that the plan 'will allow
the poultry industry to continue to be profitable, and allow
us [the USDA] to save some money as well.'"
The USDA is expected to save $90 million over three years by
reducing the number of inspectors. But these savings are dwarfed
by the savings to be made by the poultry industry — dominated by
Tyson, Pilgrim’s Pride, Purdue, and Sanderson — which stands to
save nearly $257 million annually.
Illogically enough, the USDA claims this plan will actually
improve poultry product safety and prevent anywhere
from three to five thousand foodborne illnesses per year. How
could that be, you may wonder. The answer lies in new rules that
would permit poultry producers to put all the poultry through an
antimicrobial wash, using chlorine and other chemicals. The lone
USDA inspector will continue what has been done in the past,
which is to visually inspect the birds for obvious surface
defects and fecal contamination.
Needless to say, I cannot recommend eating anything that has
been washed in chlorine and antimicrobial chemicals. We already
have a problem with antibiotics causing antibiotic-resistant
pathogens when used in the animals’ feed. I cannot foresee the
situation getting anything but worse by dousing each
bird in antimicrobials on the outside as well...
Healthy Shopping Guidelines
Buying your food from a local organic source is the ideal way
to ensure that it’s both fresh and high-quality. I strongly
advise you to avoid wilted vegetables of any kind, because when
vegetables wilt, they lose much of their nutritional value. In
fact, wilted organic vegetables may actually be less healthful
than fresh conventionally farmed vegetables.
For tips on cleaning your fruits and veggies, please see my
previous article:
7 Tips for Cleaning Fruits, Vegetables. Regardless of where
you shop, the following tips and guidelines can teach you the
tricks of healthy shopping, whether you’re shopping at Whole
Foods or a regular grocery chain:
Learn to identify:
High-quality food -- Whether you’re shopping
at a supermarket or a farmer’s market, here are the signs of a
high-quality, healthy food:
|
Grown without pesticides and chemical fertilizers
(organic foods fit this description, but so do some
non-organic foods) |
Not genetically modified |
|
Contains no added growth hormones, antibiotics, or other
drugs |
Does not contain any artificial ingredients, including
chemical preservatives |
|
Fresh (keep in mind that if you have to choose between
wilted organic produce or fresh conventional produce,
the latter may be the better option) |
Did not come from a
confined animal feeding operation (CAFO) |
|
Grown with the
laws of nature in mind (meaning animals are fed
their native diets, not a mix of grains and animal
byproducts, and have free access to the outdoors) |
Grown in a sustainable way (using minimal amounts of
water, protecting the soil from burnout, and turning
animal wastes into natural fertilizers instead of
environmental pollutants) |
Organics – There are a few different organic
labels out there, but only one relates directly to foods: the
USDA Organic seal. It’s the best way to ensure you’re getting
what you pay for when shopping organic.
The labeling requirements of the NOP10
apply to raw, fresh products and processed products that contain
organic agricultural ingredients. In order to qualify as
organic,11
a product must be grown and processed using organic farming
methods that recycle resources and promote biodiversity. (For
the complete National List of Allowed and Prohibited
Substances under the USDA organic label, see this
link.)
Genetically modified foods – Avoiding
genetically engineered (GE) food is just as important for your
health as seeking out high-quality organics. In fact, they go
hand-in-hand. Unfortunately, GE ingredients are everywhere, so
whenever you use pre-made, pre-packaged, processed foods of any
kind, genetically modified organisms (GMO’s) becomes an issue.
The ResponsibleTechnology.org has created a Non-GMO Shopping
Guide, available for free at
NonGMOShoppingGuide.com.12
By making sure to avoid all GM food products, you will actively
help change not just your own health for the better, but the
entire food industry.
Other health-harming ingredients – This is
quite a bit trickier, since there are a vast number of
additives, preservatives and food colorings that can wreak havoc
with your health in the long term. However, I would suggest
starting with the most obvious culprits, including MSG,
artificial sweeteners, and fructose. Here are helpful guidelines
for each:
- MSG – A great resource on how to find hidden sources of
MSG, please see the website
MSGMYTH.com13
for detailed listings
- Fructose – Any time you see ‘corn syrup’ or any
variation thereof, on the label, avoid it, especially if
it’s at the top of the list of ingredients.
- In his book, The Sugar Fix,
Dr. Richard Johnson reviews the effectiveness of
reducing fructose intake to help prevent or treat obesity.
His book also provides detailed tables showing the content
of fructose in different foods, including whole foods, like
fruits – an information base that isn’t readily
available elsewhere.
ALL artificial sweeteners should be avoided, including:
-
Aspartame (Equal, NutraSweet, Canderel, and
AminoSweet)
- Sucralose (Splenda)
- Acesulfame K (Sunett, Sweet One)
- Saccharin (Sweet ‘N Low, Sugar Twin)
To optimize your diet you need to educate yourself on what
‘healthy food’ really is. It’s the only way to ensure you won’t
keep falling for harmful processed food fads like no- or low-fat
(which usually means it’s loaded with harmful fructose or sugar
instead), or no or low sugar diet foods (which instead contain
artificial sweeteners, which are even worse for you). There are
few, if any, shortcuts to real health and it all starts with
what you feed your body, so make educated choices. Lastly, for
