The Pringles Company (in an effort to
avoid taxes levied against “luxury foods” like chips in the UK) once even
argued that the potato content of their chips was so low that they are
technically not even potato chips.
So if they’re not made of potatoes, what
are they exactly?
The process begins with a slurry of rice,
wheat, corn, and potato flakes that are pressed into shape.
This dough-like substance is then
rolled out into an ultra-thin sheet cut into chip-cookies by a machine.
According
to io9:
“The
chips move forward on a conveyor belt until they’re pressed onto molds, which
give them the curve that makes them fit into one another.
Those
molds move through boiling oil … Then they’re blown dry, sprayed with powdered
flavors, and at last, flipped onto a slower-moving conveyor belt in a way that
allows them to stack.
From
then on, it’s into the cans … and off towards the innocent mouths of the
consumers.”
I suspect nearly everyone reading this
likely enjoys the taste of potato chips. However, they are clearly one of the
most toxic processed foods you can eat—whether they’re made from actual potato
shavings or not.
Potato Chips are
Loaded with Cancer-Causing Chemical
One of the most hazardous ingredients
in potato chips is not intentionally added, but rather is a byproduct of
the processing.
Acrylamide, a cancer-causing and
potentially neurotoxic chemical, is created when carbohydrate-rich foods are
cooked at high temperatures, whether baked, fried, roasted or toasted. Some of
the worst offenders include potato chips and French fries, but many foods
cooked or processed at temperatures above 212°F (100°C) may contain acrylamide.
As a general rule, the chemical is formed when food is heated enough to produce
a fairly dry and brown/yellow surface. Hence, it can be found in:
·
Potatoes: chips, French fries and other roasted or fried potato foods
·
Grains: bread crust, toast, crisp bread, roasted breakfast cereals and
various processed snacks
·
Coffee; roasted coffee beans and ground coffee powder. Surprisingly,
coffee substitutes based on chicory actually contains 2-3 times MORE acrylamide
than real coffee
How Much Acrylamide
are You Consuming?
The federal limit for acrylamide in
drinking water is 0.5 parts per billion, or about 0.12 micrograms in an
eight-ounce glass of water. However, a six-ounce serving of French fries can
contain 60 micrograms of acrylamide, or about FIVE HUNDRED times over the
allowable limit.
Similarly, potato chips are notoriously high in this dangerous chemical.
So high, in fact, that in 2005 the state of California actually sued potato chip makers for
failing to warn California consumers about the health risks of acrylamide in
their products. A settlement was reached in 2008 when Frito-Lay and
several other potato chip makers agreed to reduce the acrylamide levels in
their chips to 275 parts per billion (ppb) by 2011, which is low enough to
avoid needing a cancer warning label.
The 2005 report “How Potato Chips Stack Up: Levels of Cancer-Causing Acrylamide in
Popular Brands of Potato Chips,” issued by the California-basedEnvironmental
Law Foundation (ELF), spelled out the dangers of this popular snack.
Their analysis found that all potato chip products tested exceeded the legal
limit of acrylamide by a minimum of 39 times,
and as much as 910 times! Some of the worst offenders at that time included:
·
Cape Cod Robust Russet: 910 times the legal limit of acrylamide
·
Kettle Chips (lightly salted): 505 times
·
Kettle Chips (honey dijon): 495 times
Beware: Baked Chips
May Be WORSE than Fried!
If you think you can avoid the health risks of potato chips by choosing
baked varieties, which are typically advertised as being “healthier,” think
again. Remember that acrylamide is formed not only when foods are fried or
broiled, but also when they are baked. And according
to U.S. Food and Drug Administration (FDA) data on acrylamide levels in
foods, baked chips may contain more than three times the
level of acrylamide as regular chips!
Interestingly, the same trend holds true for other foods, too, which
suggests that baking processed potatoes at high temperature may be one of
the worst ways to cook them. For instance, according
to the FDA’s data, Ore Ida Golden Fries contained 107 ppb of acrylamide in the
regular fried version and 1,098 when baked. So remember, ALL potato chips
contain acrylamide, regardless of whether they are natural or not; baked or
fried. Likewise, they will ALL influence your insulin levels in a very negative
way.
Acrylamide is Not
the Only Danger
Acrylamide is not the only dangerous
genotoxic compound formed when food is heated to high temperatures.
A three-year long EU project, known as Heat-Generated Food Toxicants (HEATOX), whose
findings were published at the end of 2007, found there are more than 800 heat-induced compounds, of which 52 are
potential carcinogens. In addition to their finding that acrylamide
does pose a public health threat, the HEATOX scientists also discovered that
you’re far less likely to ingest dangerous levels of the toxin when you eat home-cooked foods compared to industrially or
restaurant-prepared foods.
Additionally, the HEATOX findings also
suggest that although there are ways to decrease exposure to acrylamide, it
cannot be eliminated completely.
According to their calculations, successful
application of all presently known methods would reduce the acrylamide intake
by40 percent at the most—which makes me wonder whether
chip manufacturers have really succeeded at this point in reducing acrylamide
levels to within legal limits… There’s no updated data as of yet, so there’s no
telling whether they’ve been able to comply with the 2005 settlement.
For more in-depth information about acrylamide, I recommend reading the
online report Heat-generated Food Toxicants, Identification,
Characterization and Risk Minimization. In
general however, just remember that cooking food at high temperatures is ill
advised. A few of the most well-known toxins created in high-temperature
cooking include:
·
Heterocyclic Amines (HCAs): These form when meat is cooked at high
temperatures, and they’re also linked to cancer. In terms of HCA, the worst
part of the meat is the blackened section, which is why you should always avoid
charring your meat, and never eat blackened sections.
·
Polycyclic Aromatic Hydrocarbons (PAHs): When fat drips onto the heat
source, causing excess smoke, and the smoke surrounds your food, it can
transfer cancer-causing PAHs to the meat.
·
Advanced Glycation End Products (AGEs): When food is cooked at high
temperatures (including when it is pasteurized or sterilized), it increases the
formation of AGEs in your food. When you eat the food, it transfers the AGEs
into your body. AGEs build up in your body over time leading to oxidative
stress, inflammation and an increased risk of heart disease, diabetes and
kidney disease.
The Search for a
“Healthful” Chip Continues…
Like a modern-day search for the Holy Grail, chip manufacturers keep
searching for methods to improve the image of their health-harming but
profitable snacks. For example, by the end of 2011, about half of Pepsi’s
Frito-Lay brand snacks will be reformulated with all-natural ingredients. The
switch is part of PepsiCo’s master plan to tap into the healthy foods market
share. The Wall Street Journal recently reported the company
hopes to boost their nutrition business from $10 billion to $30 billion by
2020.
The company will remove dietary hazards
like monosodium glutamate (MSG), replacing it with natural seasonings, such as
molasses and paprika. Artificial colors will be replaced with beet juice,
purple cabbage and carrots. All in all, about different 60 snacks are scheduled
to get an all-natural makeover.
This is certainly a good example of how
consumer demand can alter the direction of food manufacturers in a positive
way.
The reformulated chips may end up being less bad for
you than the original formulations. However, chips will never be truly healthful. All-natural chips may be
the lesser of two evils, but if consumed regularly, they will still push your
health in the wrong direction… There’s no getting away from the fact that
modern plagues such as cancer, heart disease, obesity, and diabetes have a dietary
component, and potato chips and French fries will always be a losing bet if you
want to avoid becoming another disease statistic.
How to Avoid
Heat-Induced Toxins in Your Diet
Ideally, you should consume foods that are raw or minimally processed to
avoid these types of toxic byproducts—the more raw food, the better. My
nutrition plan emphasizes the need for at least one-third of
your foods to be consumed raw. Personally, I consume about 80 percent of my
food raw, and I find it is one of the most important factors that help keep me
healthy.
It may take you awhile to switch over
to a less processed diet, but throwing out the most obvious culprits would be a
great start.
These would include:
·
French fries and potato chips
·
All sodas (both regular and diet, as artificial sweeteners may be more
problematic than fructose)
·
Doughnuts
Healthy Eating Made
Easy
Aside from creating potentially toxic byproducts, cooking and processing
also depletes the food of valuable micronutrients, which is another reason for
eating as much raw food as possible. This includes protein sources such as
eggs. Raw whole eggs from organic, pastured chickens are
an incredible source of high-quality nutrients that many are deficient in. Raw
milk is another good example of a food that is beneficial in its raw state but becomes harmful after it is
pasteurized.
By opting for foods that will benefit your health, such as raw,
preferably organic and/or locally-grown vegetables, organic grass-fed
meats, healthy oils, raw dairy, nuts and seeds, you can change
your health for the better. These are the foods that are truly natural, and
quite easy to prepare once you get the hang of it.
Remember, eating fresh whole foods is the “secret” to getting healthier,
losing weight and really enjoying your food. It’s unfortunate that so many are
under the mistaken belief that it’s “next to impossible” to create a meal
without processed foods. Bruce Weinstein and Mark Scarbrough tackle this issue
head-on in their book Real Food Has Curves,
which is a great starting point to “relearn” the basics of how to enjoy and
prepare real food.
Once you get used to it, you’ll find you can whip up a healthful meal
from scratch in the same amount of time it would have taken you
to drive down the street to pick up fast food. The main difference will be
greater satisfaction, both physically and mentally, and perhaps even
financially, as processed foods typically end up being more expensive than cooking from scratch.
