We hope to provide you with many little-known facts
about hormones in beef in this section. All plants and
animals produce hormones. For example, some vegetables
are a much greater source of estrogen than beef. You
will learn that a serving of cabbage has 1000 times
as much estrogen than a serving of beef from a steer
that has received an estrogen implant. We explain the
truths about growth promotant issues. You will find
the reasons are quite different than you might expect.
The real issues surrounding the EU (European Union)
ban of U.S. beef are discussed.
BACKGROUND
All plants and animals produce hormones. They are
essential for life and control many aspects of metabolism,
growth and sex related characteristics. When hormones
are in the correct balance, people have a better
chance for good health and longevity. When nature's
balance is altered or interrupted, some side effects
can occur. Humans produce over 100 substances which
are various types of hormones, among them natural
steroids and eiconosoids. Some of these act as messengers
to cell receptors. If not functioning correctly,
the wrong message can be sent to the cells. Two major
groups of natural anabolic steroids are estrogens
and androgens. Males and females (both in humans
and animals) produce both types. In a female, estrogens
predominate and in a male, androgens predominate.
The best known androgen is testosterone. An example
of an estrogen is estradiol. Many man-made chemicals
have molecular structures that are similar to natural
hormones. They may be so close in molecular structure
that they can mimic natural hormones or interrupt
the natural production and balance. For example,
there are 65 man-made chemicals that are listed by
the EPA (Environmental Protection Agency), World
Wildlife Federation, or the Center for Disease Control.
Many of these chemicals are used as pesticides, but
affect our endocrine (hormone) system and brain function.
We cover this in the pesticide section of this site.
NATURAL HORMONES IN CATTLE
Cattle, like people, and to a certain extent plants,
produce estrogens and androgens. However, because
a 1200 lb. beef animal is much larger than something
small, like a potato or soybean, the proportion in
beef is hundreds and thousands of times smaller.
Take soy, for example. The average American consumes
65 lbs. of soybean oil per year. Most of it is consumed
in fast foods, snack foods, protein supplements and
baby formula. Soy contains a phytoestrogen (phytoestrogen
is plant estrogen) in the genestein group of estrogens.
One pound of soybean oil contains an average of 6,800,000
milligrams of estrogen. Compare this to one pound
of steer beef that has received a growth promoting
hormone which has an average of 8 nanograms of estrogen.
One pound of a non-implanted steer beef has only
6 nanograms of estrogen. Remember, a milligram is
a thousandth of a gram and a nanogram is a billionth
of a gram. Populations that consume more soy than
the U.S. population have a lower rate of cancer.
However, we need to look at two other things when
considering the "Big Picture". First, soy is
used in oriental cooking in other countries in a
different manner than it is used in the United States.
Usually, it is used for only a few minutes for stir
frying on low heat. In this country, soy oil is used
for frying at a very high heat. Frying creates carcinogens
which offsets some of the anti-carcinogen effort
of the phytoestyogen geneteins.
At 65 lbs per capita, we consume an average of 442
grams of estrogen per year from soy bean oil alone.
Compare this to a little over half a gram in one
year's consumption of beef. A woman in menopause
that is not taking estrogen therapy might benefit
from the estrogen in soy. A pregnant female is already
producing huge amounts of estrogen naturally may
not need more. A person who has had estrogenic cancer
should consider the amounts and types of environmental
estrogen exposure. Phytoestrogens are considered
natural environmental estrogens.
As we age, our endocrine system produces less and
less hormones. The main sex hormones estrogen and
testosterone are examples. We now know that women
who receive estrogen therapy live, on average, two
years longer than women who do not take estrogen
during menopause. Even though women taking estrogen
have a slightly higher (1 out of 1,000) risk of breast
cancer, their risk of heart attack is 50% lower.
The risk of Alzheimer's disease and osteosporosis
is 30% lower, resulting in the 2 year longer life
span. Source: "The Superhormone Promise" by William
Regelson, M.D. and Carol Colman.
I honestly believe that if you really look at the
the "Big Picture",
you'll find that extra lean Maverick Ranch Natural
Beef is one of the safest, most beneficial foods
there is. We go the extra mile to ensure this for
you because we care about you, our customers.
A 3 1/2 oz portion of steer beef has only 1.3 nanograms
of estrogen. A steer that has received an estrogen
implant only has 1.9 nanograms of estrogen per 4
oz serving. Compare this to a potato that has 245
nanograms of estrogen. If we compare soybean oil
to beef fat, the soybean oil has over 1,000,000 times
as much estrogen in the same amount of sample. For
your reference, a nanogram is one-billionth of a
gram which is analogous to one blade of grass in
an entire football field. When we change nature,
we can affect hormone balances in plants and animals.
For example, a noncastrated bull produces 1000 times
more testosterone and estrogen than a steer (castrated
animal). As a bull grows normally, the hormone balance
provides normal male characteristics such as converting
feed energy to muscle instead of fat. Additionally,
a bull is very aggressive by nature because of the
higher hormone levels. This aggressiveness leads
to stress, and stress causes higher levels of cholesterol
in the beef. Bulls often become so aggressive that
they can be dangerous to be around, whereas steers
are more docile.
When we make a steer out of a bull calf, his hormone
production is lowered and the steer takes on a metabolism
similar to a female. Steers put on more body fat
than bulls. Twenty years ago, beef was much fatter
than it is today. Steer beef used to have more fat
than protein and these steers often had 2-3 inches
of backfat and the meat was loaded with marbling.
USDA Prime beef was very bad for your heart when
eaten on a regular basis. This is the reason beef
got such a bad rap when the USDA published its nutritional
information.
Compare this to the Maverick Ranch cattle of today
that only average 1/4 inch of backfat and have much
smaller and fewer fat cells within the red meat.
There are two reasons for these changes. First, U.S.
cattlemen started importing European cattle breeds
of genetically leaner cattle to America in the 60's.
Traditionally (prior to 1965), English breeds, which
are higher in fat, dominated the market. The newly
imported breeds from continental Europe dramatically
changed the beef industry due to their lower internal
fat content. Secondly, "hormone" implants were developed
and approved by the FDA over 30 years ago.
HORMONE IMPLANTS
The first implants were estrogenic, and in 1987, androgens
were also approved by the FDA for use in cattle.
Researchers found that a steer or spayed female puts
on too much fat and does not deposit enough muscle
(red meat). They also found that replacing a very
small amount of natural hormone that had been taken
away had the same effect as exercise. The metabolism
is stimulated and feed energy is converted more to
red meat than fat. This provides a nutritionally
superior beef product and a faster gaining animal.
Muscle is denser than fat and weighs about twice
as much. Therefore, the cattle producer had a healthier
animal that produced leaner beef and also gained
weight faster.
Consumer demand was high for a leaner, healthier beef,
so use of these hormone implants became widespread.
The term "growth promotant" was coined but somehow
came to have a negative connotation. We want to emphasize
that an implanted steer still gains weight and grows
about 25% slower than a bull because the implanted
steer has less than 1% of the natural male hormone
levels of the bull. We've had numerous consumers
call us concerned about hormone levels in beef, not
realizing that 99% or more of their daily estrogen
intake is from fruits, vegetables and grains.
There is nothing wrong with estrogen from these items
unless your estrogen balance is already out of balance
with other hormones. When that imbalance happens,
we are much more likely to have disease and premature
aging. Source: Bar Diamond Laboratories
WHY THE CONTROVERSY ABOUT HORMONE IMPLANTS
IN CATTLE?
By the 1980's, a lot of natural beef companies, including
ourselves, felt that natural beef was what the public
wanted. In developing our natural beef program, we knew
that we could provide a tasty, high quality beef by
using genetically superior cattle and testing all the
beef in our program for the absence of antibiotics and
pesticides. About the same time, the EU banned U.S.
beef in Europe, supposedly because of the added growth
hormones.
This was, in reality, a trade barrier designed to
keep U.S. beef from entering Europe and putting a
greater burden on European governments who subsidize
cattle production in their own countries. More beef
from the United States in Europe meant more cash
subsidization for European cattle producers by their
governments.
European scientists have never been able to identify
any harmful effects in humans from eating U.S. raised
beef. The practice in Europe is to use bull beef
rather than steer beef, so natural hormone levels
of European beef is actually much higher than in
the U.S. One TV program reported that the beef that
had received growth promotants caused early maturity
in children in South America. This was reported without
any scientific fact to back up their story, and researchers
later proved the story incorrect.
WHAT IS MAVERICK
RANCH'S POSITION ON HORMONE IMPLANTS IN CATTLE?
14 drug companies produce FDA approved implants. These
are all estrogenic or androgenic compounds. In general,
these are small pellets, slightly larger than a pin
head, and are implanted in the middle back of the animal's
ear. These implants are gradually released over a 60
to 200 day period and in effect, stimulate the animal's
metabolism.
All scientific studies
prove there is zero risk to humans, and laboratory tests
consistently support this finding. In 1995, several
very strong androgen implants became popular. Their
use tends to make steers a little more like bulls, and
some of the beef becomes too lean to qualify for USDA
Select or Choice grade which are the only USDA grades
that Maverick Ranch accepts. Colorado State University
has recently completed a study that shows that several
implant strategies not only reduce USDA grade, but they
make the beef so lean that it decreases tenderness and
palatability.
A LABORATORY TESTING SYSTEM LIKE OURS IS THE
ONLY WAY TO PRODUCE TRULY VERIFIABLE NATURAL
BEEF THAT WE BELIEVE EXCEEDS EVEN ORGANIC STANDARDS.
Some organic standards permit direct pesticide use
that is necessary, but leaves no way to test and
reject animals that are overdosed or have a detectable
residue.
NUTRITIONAL INFORMATION
In the past, beef has been portrayed negatively by
the media and in some nutritional diets and programs.
The USDA publishes Handbook 8-13 which contains nutritional
data on beef. We believe that the handbook doesn't
take into consideration the modern lean cattle of
today. This data has only been updated a few times
in the last 50 years. The current printed material
is old; they have stopped printing a hard copy of
the information because the volume would be too large
and the information frequently changes. There is,
however, current info on the web available to consumers
upon request.
Their website is www.nalusda.gov/fnic/index.html or
you can phone 301-734-8491. Look
at Maverick Ranch's lean nutritionals.
Today's Maverick Ranch Natural Beef, in most of our
popular cuts, has nutritional values that exceed
most fish and chicken. When you consider pesticides
and pathogenic bacteria, Maverick Ranch Beef is one
of the safest meat products on the market.
