Introduction
The biggest
problems confronting America and the rest of our planet are
disease, hunger, environmental devastation, and death. Every one
of these traces its roots more or less directly to animal agriculture.
Although most people are motivated by health concerns, it is important
to realize that dietary choices have much broader implications for
planetary survival.
Heart
disease, stroke, cancer, diabetes, and other chronic diseases
kill 1.4 million Americans annually. Infectious diseases also referred
to as food poisoning, sicken millions and kill thousands. A dozen
panels of experts have associated the former with the consumption
of animal fat and meat. The latter are propagated by E. coli, Salmonella,
and other pathogens that thrive primarily on meat, egg, and dairy
products.
Hunger
afflicts more than a billion people worldwide and kills 24,000
per day, mostly children. A major factor is the waste of foodstuffs
fed to animals raised for food, rather than to starving people.
This was first documented in Frances Moore Lappe's 1972 classic
Diet for a Small Planet and was reaffirmed at the 2002 World Food
Summit in Rome. For more information on the connections between
hunger and animal agriculture, visit the Global
Hunger Alliance.
Most wars are fought over control of natural resources: land,
water, oil, and minerals. Yet, animal agriculture is by far the
largest user and despoiler of natural resources.
In addition, animal agriculture directly kills annually nearly 50
billion animals worldwide, after subjecting them to the cruelties
of factory farming. It also kills uncounted numbers of wildlife
on land and in the seas.
Yet, these issues are not discussed in our nation's schools
or universities, and they are barely discussed by national decision-makers.
Nutrition education has been largely relinquished to the very meat
and dairy industries that create these problems, and we are left
to consume the harmful products of these industries. The responsibility
for this tragedy must be shared by individuals, Congress, USDA,
and of course, the meat, egg, and dairy industries.
*************************************************************************************
Diet and Health
Consumption
of fruits, vegetables, whole grains, and legumes is crucial to good
health. These foods supply essential nutrients, fiber, antioxidants,
and phytonutrients, which reduce the risk of heart disease and cancer.
Plant-based foods contain little saturated fat, pesticides or pathogens,
and no cholesterol, hormones, antibiotics, or heavy metals. There
is evidence that children and adults who consume wholesome plant-based
meals enjoy more energy and improved intellectual performance.
Conversely, meat and dairy products come laden with saturated
fats, cholesterol, hormones, pathogens, and antibiotics. They
lack carbohydrates and fiber and most vitamins and minerals, all
essential to good health.
Protein
Protein
provides the body with essential amino acids and assists in
the manufacture of tissue cells, antibodies, and enzymes. It also
helps maintain the proper acid-alkali balance, immune protection,
and transmission of nerve impulses.
Protein is found in many plant foods, particularly legumes,
grains, seeds, nuts, and vegetables. In the US, common legumes are
soybeans (including tofu and soymilk), garbanzo beans, kidney beans,
black beans, pinto beans, peas, and lentils. Common grains are rice,
wheat, and corn. Legumes and grains are also good sources of complex
carbohydrates.
The meat industry has raised some alarm by suggesting that
protein from plant sources may not be as 'complete' as that from
animal sources. Fortunately, any essential amino acids that may
be missing in grains are available in legumes or vegetables and
vice-versa. Our liver stores and redistributes the essential amino
acids where they are needed. This is precisely how the animals raised
for food get their 'complete' proteins.
Likewise many people are concerned about getting enough protein. This concern is misplaced as most Americans consume an excessive
amount of protein, which stresses the kidneys and is stored as fat.
The average protein RDA (recommended daily allowance) for an adult
male is 63 grams and 50 grams for an adult female, but the average
consumption for an Americans is 103 grams, of which 70 grams comes
from animal sources.
Fats
Some fats are essential to good health, while others contribute
to obesity, heart disease and certain types of cancer. The official
government recommendation from the Dietary Guidelines for Americans
is that only 30% of our daily calories should be derived from fat
and no more than 10% from saturated fat. Other health experts recommend
even lower limits.
The four key types of fats are:
1. Monounsaturated
2. Polyunsaturated
3. Hydrogenated
4. Saturated
Monounsaturated fats are found in olive, canola, peanut, almond,
avocado, and sunflower oils. They appear to reduce blood levels
of LDL, or 'bad' cholesterol.
Polyunsaturated fats are found in corn, soybean, safflower,
and flax oils. They lower total blood cholesterol levels including
HDL, or 'good' cholesterol. However, they contain high levels of
the essential omega-3 fatty acid.
Hydrogenated fats, also known as trans-fatty acids, are polyunsaturated
fats that have been processed into a solid form, as in margarine
and shortening. These fats elevate 'bad' cholesterol and lower 'good'
cholesterol. Moreover, the hydrogenation process causes molecular
damage that has been linked to elevated cancer risk.
Saturated fats are found primarily in meat and dairy products,
but also a few plant foods like avocados, coconuts, and vegetable
shortening. The body stores excess proteins and carbohydrates are
as saturated fats. The liver uses saturated fats to manufacture
the body's natural supply of cholesterol. Excessive dietary intake
of saturated fats raises the blood cholesterol level, and places
increased stress on the liver.
Carbohydrates
Carbohydrates are the main source of blood glucose, which
fuels the body's cells, and is the only source of energy for the
brain and red blood cells. The Dietary Guidelines recommend that
60% of total daily calories come from carbohydrates. Carbohydrates
are found almost exclusively in plant foods such as fruits, vegetables,
grains and legumes.
Complex carbohydrates, found in vegetables, legumes, and
grains, provide a sustained source of glucose. The dietary fiber
in complex carbohydrates cleans the digestive tract and ties up
cholesterol-producing compounds, reducing the risk of colon cancer
and cardiovascular diseases.
Simple carbohydrates, in fruits, are transformed into glucose
more rapidly. Refined grains and sugars, contained in most processed
foods and soft drinks, produce spikes in the blood glucose level,
requiring excessive release of insulin - a possible precursor to
hypoglycemia and diabetes.
Vitamins and Minerals
Plant foods are the only sources of all the vitamins (except
for B12) and minerals essential for good health. The only vitamins
and minerals claimed for meat products are the B complex, iron,
and zinc, which are widely available in plant foods. Iron is particularly
plentiful in legumes, green vegetables, and dried fruit. Its absorption
rate improves in the presence of Vitamin C, in dried fruits. Zinc
is available in legumes, corn, nuts, and seeds.
Though dairy products are widely touted as a source of calcium,
they can actually contribute to osteoporosis. The calcium in
dairy products comes with the high price of saturated fats, hormones,
and antibiotics. Moreover, the excessive protein content of dairy
products leaches calcium from the bones. Milk is for infants. There
is no need for adults to consume the milk of cows, goats or any
other animal. Indeed, most adults worldwide are lactose intolerant
(unable to digest the lactose sugar in dairy products). Green leafy
vegetables provide ample calcium, offer a calcium absorption rate
nearly double that of dairy products, and do not leach calcium from
the bones.
*************************************************************************************
Diet and Disease
Children
Across the country, meals are dominated by animal products and are laden with saturated fat, cholesterol, excess protein, hormones,
drugs, and salt. These are diets that defy the Dietary Guidelines
for Americans and promote bacterial infections, diabetes, several
forms of cancer, and other chronic diseases that cripple and kill
nearly 1.4 million Americans annually. These diets are particularly
damaging for children who are still growing and whose early dietary
habits become lifelong addictions.
Consider the following:
- School lunches contain
33% of calories from fat, including 12% from saturated fat,
while U.S. Dietary Guidelines recommend 30% and 10%, respectively.
- 90% of children
consume amounts of fat above the recommended level.
- Less than 15% of
children eat the minimum daily recommended servings of fruit,
and 35% eat no fruit on a given day.
- Only 17% of children
consume the minimum daily recommended servings of vegetables,
and 20% eat no vegetables on a given day.
- 15% of children
ages 6 to 19 are overweight, and the Surgeon General has reported
that obesity is reaching epidemic proportions, particularly
among children.
- 25% of children
ages 5 to 10 have high cholesterol, high blood pressure, or
other early warning signs for heart disease.
- As many as 30,000
children have Type II diabetes, once limited largely to adults.
- The past decade
has had 300 outbreaks of school food poisoning affecting 16,000
students.

Vascular
Diseases
Vascular diseases, including heart diseases and stroke, are
caused by blockage of the arteries that supply oxygenated blood
to the body's vital organs. The blockages are caused by a build-up
of fatty plaque along the artery walls. This condition is called
atherosclerosis. Total blockage of an artery leading to a portion
of the heart or the brain brings on a heart attack or stroke. Nearly
860,000 Americans die each year of vascular diseases.
Diets laden
with saturated fat,
cholesterol, and salt are the key factors in the incidence of cardiovascular
diseases. Cholesterol is the key component of the fatty plaques.
Saturated fats raise blood cholesterol level more than any other
factor. Salt consumption promotes water retention and blood volume,
leading to hypertension, which contributes to the incidence of heart
disease and stroke, as well as to rupture of blood vessels.
All animal foods contain cholesterol, but no plant foods do.
In fact, antioxidants and folic acid in plant foods protect arteries
from plaque formation. Plant foods are also naturally low in saturated
fats and salt, and the potassium in plant foods reduces hypertension.
Cancer
Cancer is actually a variety of diseases that occur when
the cells grow out of control, spread through the body, and interfere
with the function of a vital organ. Cancers of the lung, breast,
prostate, and the digestive tract have all been linked with a diet
high in animal foods. Nearly 260,000 Americans die of these types
of cancer each year.
Consumption of animal fats raises blood testosterone and
estrogen levels that promote prostate and breast cancers, respectively.
Carcinogenic pesticides spread on animal feedcrops accumulate in
animals' fatty tissues. In the digestive tract, animal fats interact
with bile acids to release carcinogens. All animal fats heated to
high temperatures, as in deep-fried foods, also form carcinogens.
Nitrites in hot dogs and other 'cured' meat products are known carcinogens.
The Insulin Growth Factor (IGF) in dairy products promotes malignant
cell growth.
Conversely, plant foods contain fiber, which helps prevent
cancer of the digestive tract by speeding food transit before formation
of the carcinogens and reduces the risk of breast cancer, perhaps
by lowering estrogen level. Plants also contain antioxidants and
flavones that impede formation of cancer cells.
Diabetes
Animal fat in the bloodstream blocks insulin from playing
its vital role. The cells of our body feed on glucose that is escorted
by insulin. This causes adult-onset or Type II diabetes. The incidence
of this disease has been growing among both adults and children
because of their faulty diet. In some children, cow's milk generates
antibodies that destroy the pancreatic cells that produce insulin,
leading to Type I diabetes. Diabetes is a serious disease, which
causes shortness of breath, vomiting, dehydration, and eventually
contributes to heart and kidney diseases. Diabetes kills nearly
70,000 Americans each year.
Other
Chronic Conditions
Kidney stones and other kidney diseases are typically associated
with excessive consumption of meat, dairy, and other proteins that
these organs convert into fat and waste products. Kidney diseases
kill nearly 40,000 Americans each year.
Dairy products are responsible for a number of serious digestive and allergic reactions. Nearly 50 million Americans, including 75%
of African Americans and 90% of Asian Americans suffer from severe
cramps caused by lactose intolerance. Common allergic reactions
include asthma, skin rashes, and ear infections.
Infectious
Diseases
Pathogens that thrive in animal foods are the primary causes
of infectious diseases, commonly referred to as food poisoning.
The biggest culprits are Escherichia coli, Salmonella enteritidis,
Campylobacter jejuni, and Listeria monocytogenes. These diseases
cause several days of misery and occasional deaths. The Centers
for Disease Control estimate that 9 million cases occur annually,
though most are not reported.
All meat and poultry products are required to carry warning labels because the USDA has been unable to vouch for their safety. In 2002,
following repeated incidents of school food poisoning, the Department
decided to irradiate meat destined for the school lunch program.
Meat products also contain antibiotic residues, which build up resistance
in pathogens, and render antibiotics less effective in treating
infectious diseases.
*************************************************************************************
Diet and World Hunger
Worldwide,
nearly a billion people suffer from chronic hunger. 24,000 people
per day or 8.8 million per year die from hunger or related causes.
Three-fourths are children under five. Chronic hunger causes stunted
growth, poor vision, listlessness, and susceptibility to disease.
Global malnutrition is largely the consequence of inequitable
distribution and waste of food resources. Only 10% of hunger
deaths are attributed to catastrophic events like famine or war.
Hunger is a complex problem, but huge amounts of waste occur because
of non-sustainable practices related to animal agriculture, such
as depletion of cultivable land, topsoil, water, energy, and minerals,
and the extremely inefficient process of converting plants-based
foods into animal-based foods. More information is available from
the Global Hunger Alliance.
Role
of Animal Agriculture
A meat-based diet requires 10-20 times as much land as a plant-based
diet. Nearly half of the world's grains and soybeans are fed
to animals, resulting in a huge waste of food calories. The extent
of waste is such that even a 10% drop in US meat consumption would
make sufficient food available to feed the world's starving millions.
Moreover, animal agriculture has been devastating the world's
agricultural land. The process begins with clear-cutting of
forests to create cattle pastures. Eventually, the pastures are
plowed under and used to grow animal feedcrops. Depletion of topsoil
and minerals begins soon after the trees are cut down and escalates
with tilling. Without the plant growth to hold it in place, topsoil,
laden with minerals, fertilizer, and organic debris, is carried
by the runoff of rain and melting snow into nearby streams. The
insatiable demand for animal feedcrops leads to the use of sloping
land with greater runoff and arid land requiring irrigation. Irrigation
accounts for more than 80% of all water available for human use,
leading to widespread water shortages.
Future
Outlook
Western agribusiness interests, faced with saturated markets
and increasingly stringent environmental regulations at home, seek
to export factory farming practices and to expand the demand for
their products in developing countries.
This expansion of the meat industry brings a number of disastrous
consequences. It would exacerbate the mal-distribution and waste
of food resources. The resulting drawdown of grain supplies would
precipitate major famines. The public health impacts would impose
an intolerable economic burden. The impacts on soil, water, and
wildlife would threaten fragile ecosystems.
The sustainable cultivation of plant foods favored by developing
countries offers a safe, nutritious, and affordable solution to
hunger and malnutrition. Fruits, vegetables, grains and legumes
can be grown in most climates and on small plots of land. Such crops
require minimal investment in equipment, fertilizers, pesticides,
water, and energy, and they cause negligible soil degradation and
water pollution.
**************************************************************************************
Diet and the Environment
Animal
agriculture is more devastating to our natural environment than
all other human activities combined. This devastation impacts land,
water, air, and wildlife.
Land
Animal agriculture has been turning lush forests and prairies
into barren deserts since the dawn of human history. The process
begins with clear-cutting of forests to create pastures for cattle
and other ruminants. This is a major loss, because trees provide
wildlife habitats, keep topsoil in place, replenish groundwater
aquifers, absorb carbon dioxide, and stabilize climate.
As the pastures become overgrazed, they are plowed under
and turned into animal feed croplands. With little or no plant growth
to hold it in place, topsoil is carried by rain and melting snow
into streams and lakes, and its productive capacity is lost forever.
This process is accelerated by the use of marginal sloping lands
to meet the insatiable demand for animal feed.
Water
The rain and melting snow that runs off animal feed croplands and factory farms dumps more pollution into our lakes, streams,
and estuaries than all other human activities combined.
The cropland runoff contains soil particles, salts, organic
debris, fertilizer, and pesticides. Soil particles smother fish
eggs and bottom dwelling organisms and block stream flow. Salts,
primarily sodium and potassium chloride, raise the salinity of the
water, rendering it unsuitable for certain organisms. Organic debris
feeds microorganisms that deplete the water's oxygen supply and
kill the fish. Fertilizers spur algal blooms that smother or actually
attack aquatic organisms. Pesticides kill all living organisms.
Animals raised for food in the US produce 130 times the amount
of waste that people do. This waste, containing pathogens and
hormones, is stored in huge open cesspools, euphemistically called
'lagoons. 'Eventually, this waste winds up in the nearest waterway,
killing aquatic organisms directly or through formation of algal
blooms. Waste from mid-Atlantic pig and poultry factory farms has
destroyed fisheries along the Eastern seaboard and the Gulf of Mexico.
Some of the waste leaks into the ground, poisoning vital groundwater
supplies.
Animal agriculture's insatiable demand for land presses into
service arid lands that require irrigation. Irrigation now accounts
for more than 80% of all water available for use in the US and leads
to critical water shortages, particularly in the Western states.
Air
Wind erosion from animal croplands is the largest source
of airborne particles, which irritate respiratory passages and make
them more susceptible to respiratory infections. Factory farms produce
a stench that poses a major nuisance (and possibly hazard) to neighbors
for miles around. Methane emitted by cattle and carbon dioxide generated
by the power plants that operate factory farms are major contributors
to global warming.
*************************************************************************************
Diet and Animals
Each
year, ten billion cows, pigs, sheep, and other innocent, sentient
animals are caged, crowded, deprived, drugged, mutilated, and manhandled
in US factory farms. They are then hauled to the slaughterhouse
and slaughtered under atrocious conditions. Ten percent never make
it to the slaughterhouse, dying from stress-induced diseases or
injuries.
Cows
& Calves
Beef cattle are typically enclosed in feedlots, which pack
tens of thousands of animals per unit. Cows have no protection from
rain or snow, freezing wind, or searing heat. They are castrated,
dehorned, and branded with no anesthesia or surgical training.
Dairy cows spend their entire lives chained to metal poles on concrete floors inside dark barns. They are allowed limited movement
twice a day, when they are herded into 'milking parlors' and hooked
up to milk machines. Many cows are injected with bovine growth hormone
to boost milk production to unnaturally high levels, causing infectious
udder diseases and additional stress to the animals.
Dairy cows are kept perpetually pregnant. Calves are torn
from their mothers at birth and chained by the neck in tiny, filthy
wood crates to keep their flesh soft. They are fed a liquid formula
that is deficient in iron and fiber to keep their flesh pale. These
conditions breed diarrhea, respiratory disease, and anemia. The
calves are deprived of natural food, fresh air, and their mothers'
love. After 16 weeks, they are dragged to slaughter and served as
veal.
Pigs
Breeding sows suffer a similar fate. They are kept constantly
impregnated in tiny metal 'gestation stalls,' until they are ready
to give birth. Then they are immobilized further in 'farrowing pens,'
where they give birth and nurse their litter of 10-12 piglets. The
natural nursing period of 12 weeks is cut to 2-4 weeks, so that
the sows can be impregnated again. After 3-4 years, their exhausted
bodies are sold for slaughter.
Over 20 percent of the prematurely weaned piglets die of stress
and disease. They are the lucky ones. Those who survive are
tagged and castrated without anesthesia, then placed in stacked
wire cages euphemistically called 'nurseries.' Instead of mother's
milk, they are force-fed a synthetic formula. When the pigs are
able to eat solid food, they are transferred to large, crowded pens.
Here they are fed for six months until slaughter.
Chickens
and Turkeys
300 million turkeys and 9 billion chickens are slaughtered
for human consumption each year in the US. These birds represent
over 95% of all land animals slaughtered for food. They are crowded
into large, dimly lit sheds that hold as many as 10,000 birds. Because
they are bred to gain weight quickly, many birds are crippled by
their own weight and unable to walk. They are then unable to get
to food and water or to defend themselves from the other birds who
trample them on the way to the feeding station. Over time, the building
fills with the poisonous stench of hydrogen sulfide, ammonia, and
methane. After seven weeks, the animals are crammed into wood cages
for transport to slaughter.
Chickens bred for egg production undergo a sex selection at birth. The males are dumped into plastic bags, left to suffocate slowly,
and ground up for chicken feed. The females are debeaked with a
hot iron to prevent stress-induced cannibalism. They are crammed
5-7 birds into 20x24" 'battery cages,' stacked on top of one
another. They must stand on a sloping wire mesh floor, which cuts
their feet, while the wire mesh walls tear out their feathers. The
birds are alternately starved or overfed to manipulate egg production.
Transport
and Slaughter
Animals are hauled to slaughter for many hours without food,
water, or rest, while exposed to extreme temperatures. Many die
in transit, and those too sick or injured to walk are dragged with
chains to the kill floor.
Consumers have no clue about the cruelty they subsidize. At the slaughterhouse, some of the animals are skinned, dismembered,
or drowned in boiling water while still conscious. They are then
cut into smaller pieces, wrapped in cellophane, and presented at
the supermarket counter.
Wildlife
In addition to the ten billion animals killed by animal agriculture
each year for human consumption, hundreds of thousands of prairie
dogs, coyotes, wolves, mountain lions, bears, bison, and other wild
animals are shot, maimed, poisoned, and burned alive by farmers
and government agents to keep them from interfering with agricultural
operations. Tens of millions of starlings and blackbirds are poisoned
each year to keep them from eating animal feed.
An even greater threat to wildlife is posed by the destruction
of their habitats. Animal agriculture turns hundreds of acres of
forest, wetlands, and other habitats into grazing and croplands
to feed farm animals.

Conclusion & More Info
Every day, several times
a day, we make dietary choices that directly affect our health, the
health (hunger) of others, the environment, and of course animal suffering.
Individually and combined these issues are overwhelming, but changing
our food choices to wholesome and compassionate plant-based foods is the
best way to help ourselves while helping others.
