YOU ARE WHAT YOUR ANIMALS EAT
by Jo Robinson
In my investigation into pasture-based farming, I've stumbled upon an alarming
void: few people care about the link between the diet of our livestock
and the nutritional content of their products. "Feed animals anything
you want," the research suggests, "and it makes no difference to their
meat, milk, or eggs."
Browse through the animal science journals, for example, and you'll see
that the goal of most feeding experiments is to increase production and
minimize costs. Period. As long as the feed is cheap and the
animal gets fat, anything goes.
Here’s a glaring example. A 1999 study published in The Journal of
Animal Science explored the desirability of feeding stale chewing gum and
its wrappers to cattle. Wonder of wonders, the article concluded
that a bubble gum diet was a net benefit. I quote: ”Results of both experiments
suggest that [gum/packaging material] may be fed to safely replace up to
30% of corn-alfalfa hay diets for growing steers with advantages in improving
dry matter intake and digestibility.” In other words, feed a steer
a diet that is 30 percent bubble gum and wrappers, and he'll eat more.
Needless to say, there was no mention of the nutritional value of the resulting
meat. (When I first read these articles, I assumed that no one would actually
feed bubblegum to their animals, despite the "positive" results of the
studies. Then a professor of animal science drove me by a Beechnut gum
factory in upstate New York where dairy farmers used to buy truckloads
of bubblegum to feed to their cows. The only reason the practice stopped
is that the factory closed down.)
Researchers studying human nutrition have been just as slow to see the
connection between animal diets and human diets. To most dieticians, beef
is beef, eggs are eggs, and milk is milk. Few pay any attention to
what the animals were fed or how they were raised. Thus, when the USDA
guidelines say “eat less red meat,” the edict applies to all red meat,
whether it’s a fatty steak from a grainfed cow, or a lean steak from a
grassfed cow with its invisible bounty of omega-3s, vitamin E, and CLA.
I have spent the past three years trying to connect the dots between animal
feed and human food. It's been arduous work. For the past 50
or so years, virtually all our information about the nutritional value
of meat, eggs, and dairy products has come from grainfed animals. To discover
the nutritional value of grassfed products, I've had to search through
moldy journals published before the advent of factory farming, extrapolate
from small studies financed by individual farmers, and rely on studies
based in Ireland, Australia, or New Zealand—parts of the world where pasture-based
farming still survives.
Finding the amount of vitamin E in grassfed beef has been my biggest challenge.
I began to search for this data as soon as I learned that grass has 20
times more vitamin E than corn or soy. Given the magnitude of this
difference, I reasoned that meat from grassfed animals must have an extra
helping of vitamin E.
Diligently, I searched the scientific
record. At long last, I located one study that compared the amount
of vitamin E in grainfed and grassfed meat. The impetus for the study
came from disgruntled Japanese buyers who complained that the meat from
American feedlot cattle spoiled more quickly than the meat from Australian
free-range cattle. To find out why, the Americans decided to measure the
vitamin E levels in the two types of meat. (Antioxidants such as vitamin
E are known to prolong shelf life.) Their tests revealed that meat from
grassfed cattle has three to four times more vitamin E than meat from feedlot
cattle. How did they use this data? They decided to add more
artificial vitamin E to feedlot diets.
What can be done about the lack of interest in raising animals in a more
natural environment? The underlying problem is that most of our animal
research is funded by commercial interests--- primarily the grain, chemical,
pharmaceutical, farm equipment, and meat-packing companies. Together,
these vertically integrated behemoths have a multi-billion dollar investment
in perpetuating factory farming. The USDA, meanwhile, devotes the
bulk of its effort to supporting and tweaking the feedlot system. It is
more willing to spend $100,000 on a new piece of equipment designed to
measure the odor that wafts off manure lagoons than to spend a similar
amount on exploring the odor-free grazing system.
What
will it take to rearrange the priorities of the USDA? An enlightened public.
And what will it take to enlighten the public? A sustained media campaign.
But since there is no money to fund such a campaign, the breakthrough will
have to come from investigative journalism. A journalist from a major TV
show such as "60 minutes" or "Dateline" or a prestigious newspaper such
as The New York Times or The Washington Post will decide to explore the
stunning differences between raising animals on pasture and in confinement.
Building on this ground-breaking work, Bill Moyers or another respected
TV journalist, will produce a one-hour documentary on pasture-based farming.
The program will conclude---as it must---that raising animals on pasture
is better for consumers, animal welfare, the environment, and small-scale
farmers. Before long, dozens of TV shows, newspapers, and magazines will
have followed suit and launched their own investigations into the new phenomenon.
All of a sudden, grassfarming will be the talk of the town. Serving organic
meat won’t win points in Los Angeles anymore unless it’s grassfed as well.
Meanwhile, Ted Turner will have stopped sending all of his bison calves
to feedlots to be fattened like cattle, and by 2005, his “Turner Reserve
Grassfed Bison” will be the thing to serve at celebrity gatherings.
Propelled by this groundswell of interest, investors and institutions will
finally devote more time, money and energy to supporting pasture-based
farming.
Will grassfarming really become the darling of the media? Only time will
tell. But even if it doesn't, there is evidence that grassfarming
is gathering momentum the old fashioned way—word of mouth. Friends
are telling friends about the health benefits of pastured animal products,
and they’re turning the curious into converts by inviting them over to
share in a feast. I’ve gotten calls from quite a few grassfarmers
this year who say they’re having trouble keeping up with demand.
The good news about grassfarming seems to be spreading---one satisfied
customer at a time!
