Most
people are eating a poison every day without giving it a second thought. This
substance can increase belly fat and consuming even small amounts (2% of total
energy intake) is consistently linked to coronary heart disease. The research
also says that this stuff can increase visceral fat, contribute to insulin resistance,
increase risk of type 2 diabetes, increase bad cholesterol, decrease good cholesterol,
trigger systemic inflammation and adversely affect almost every cell in your body.
What
substance could be so harmful that it causes all of these health problems and
yet is so prevalent in our food supply that most people are eating dangerous amounts
every single day? This industrially manufactured ingredient is called Trans fatty
acids (TFAs).
TFAs
are not found in nature, with the exception of some ruminant-derived TFAs
in certain dairy products (usually contributing less than 0.5% of total caloric
intake). TFAs come mostly from the industrial hydrogenation of vegetable
oils, which alters the natural cis configuration of the oils to the trans configuration.
If you see partially hydrogenated oil in the ingredients list of any
food product, then it contains TFAs.
TFAs
have been studied for decades, but were largely ignored until the past several
years. Research papers linking trans fats to heart disease date back to the 1970s.
In 1994, the Center for Science in the Public Interest petitioned the Food and
Drug Administration to put trans fats on food labels (didnt happen until
2006). Since 2006, TFAs have thankfully received a decent amount of publicity
when they were in the news regarding new food labeling laws and the banning of
their use in restaurants in some states.
New
studies have been published in the past year confirming the dangers of TFAs.
Four recent studies indicated 24, 20, 27 and 32% higher risk of myocardial infarction
(MI) or CHD death for every 2% energy of TFA consumption isocalorically replacing
carbohydrate, SFA, cis monounsaturated fatty acids and cis polyunsaturated fatty
acids, respectively.
TFA
intake in the United States still averages 2-3% of total energy intake, 4% in
some developing countries where fast food is being introduced and as high as 8-10%
in certain subgroups (who eat large amounts of baked goods, fried foods, pastries,
doughnuts, etc). The government recommended maximum is 1% of total energy intake
(2 grams!). Some experts say there is NO safe level of TFA intake.
Legislation
has been enacted in some states banning the use of TFAs in restaurants. It was
big news New York. As of 2008, 11 cities and counties have adopted regulations
to restrict TFA use in restaurants. However, industrial TFA use is still widespread
and lots of people are still scarfing them down every day.
If
Trans fats are so dangerous, why is their use so widespread? Dietary fat expert
Udo Erasmus put it this way: TFAs are a food manufacturers dream:
an unspoilable substance that lasts forever. TFAs are cheap and for
countless food products, they can prolong shelf life, allow easy transport, provide
solidity at room temperature (to make spreads), and increase suitability for commercial
frying.
Although
most people have heard of TFAs, the bad news is that this increased awareness
has not been enough to translate into behavior change.
A
study recently published in the Journal of The American Dietetic Association (ADA)
found that in 2007, 73% of Americans knew that TFAs increased risk of heart
disease, compared to 63% in 2006. However, the bad news is that 79% of Americans
could not name 3 foods that contain trans fats. 46% of Americans could not name
any sources of trans fats on their own.
Knowledge
about food sources of fats remains low says Robert Eckel, professor of Medicine
at the University of Colorado.
Public
health messages have been raising awareness, but they havent been enough.
TFAs are bad for you. Ok, so now what? What you really need
are some simple behavior guidelines and a list of foods to eat very infrequently
if you eat them at all.
Here
are some good places for you to start.
4
Ways to Avoid Trans Fatty Acids
1.
Eat mostly foods that do not have a label. At the risk of stating the obvious,
if you dont eat anything that comes in a box or package with a label, then
you wont ever consume manmade TFAs. If your diet consists primarily
of fruits, fibrous vegetables, root vegetables, beans, legumes, brown rice, unprocessed
whole grains, nuts, seeds, eggs, fish and lean meats, youre home free.
2.
Watch for label loopholes. WARNING: Food companies are lying to you on their product
labels to make you think their foods are TFA-free. The front of their package
may say ZERO grams of trans fats, and yet there is hydrogenated oil
listed in the ingredients. How could that be? There is a label loophole where
the government allows companies to claim zero trans fats if there is less than
a half a gram per serving. So the food companies sneakily manipulate their serving
sizes until the servings are so small that the TFA content falls below the per
serving limit.
3.
Read ingredients lists. The primary source of TFAs is partially hydrogenated
vegetable oils. In particular, soybean, sunflower, cottonseed and palm oils are
frequently hydrogenated. Your first step then, is to read food labels on any packaged
products and look at the ingredients list. If it contains partially hydrogenated
oils, it contains TFAs.
4.
Avoid foods that contain TFAs most of the time. TFAs are commonly
found in baked goods (bakery), fried foods and packaged convenience foods, especially:
In
2002 when I published the first edition of my ebook, Burn
The Fat, Feed The Muscle, I warned my readers of the dangers of trans
fatty acids. I was not the only one either. Years ahead of the 2006 law requiring
trans fats to be listed on food labels and the 2007-2008 restaurant TFA bans,
numerous health professionals were already warning people to stay away from TFAs.
Not
enough people heeded the warnings, while meanwhile, politics and commercial interests
delayed legislation. No doubt, skyrocketing rates of obesity, diabetes and cardiovascular
disease can be largely linked to the continued use of these artificial fake food
additives. In the US alone, 1,700,000 new cases of diabetes, 233,600 diabetes-related
deaths, 600,000 myocardial infarctions and 451,300 coronary heart disease-related
deaths are reported every year.
A
campaign for better education and lifestyle change is worth supporting. As researchers
from Harvard said, A comprehensive strategy to eliminate the use of industrial
TFA in both developed and developing countries, including education, food labeling,
and policy and legislative initiatives, would likely prevent tens of thousands
of CHD events worldwide each year.
For
a healthy and balanced lifestyle, and for better long-term compliance, Im
rarely in favor of tagging any foods as totally forbidden or to use
words as strong as poison in describing foods. But if there are any
exceptions, trans fats are one of them.
If
you are unable or unwilling to eliminate TFAs from your diet completely,
then you would be wise for the sake of your health and your familys health,
to keep foods containing TFAs to a bare minimum and avoid eating any TFA-laden
foods on a daily basis.
Last,
but not least, be on guard, because history tells us that when one harmful food
additive is banned, it is often replaced with another, which is sometimes even
worse. Thats why item #1 on my list of four ways to avoid trans fatty acids
is the best way to avoid anything that is harmful to your health.
