You Are What You Eat Essay, Research Paper

“You are what you eat”, goes a famous saying. And if that is truly the case, then a lot of Americans

would appear to be unhealthy, chemically treated, commercially raised slabs of animal flesh. And while

that is not a particularly pleasant thought, it is nonetheless an description of the typical American

omnivore who survives on the consumption of Big Macs and steak fajitas.

But there are individuals who do not follow this American norm and have altered their diets so that they

do not consume any meat. These people are vegetarians, and they are the new breed of healthy

Americans who refuse to poison themselves with fats, cholesterol, and the other harmful additives that

come from meat. And while once thought to be a movement that would never gain much momentum, it

has nonetheless moved itself to the forefront of Americans? healthy diets.

The word vegetarian, used to describe the diets of people who do not consume animal flesh, was not

used until around the mid-1800s. The concept of vegetarianism, however, dates back much further.

The Greek philosopher Pythagoras, considered by many to be the father of vegetarianism, encouraged

a non-meat diet among his followers as a diet that was the most natural and healthful (Messina 3).

A vegetarian diet excludes the consumption of meat, and can be exercised by people for a number of

reasons. The largest majority of individuals chose vegetarianism for health related reasons. For

example, someone with an ulcer might be prescribed a strict diet of vegetables in order to promote the

healing process. Or someone with a dangerously high level of cholesterol might be advised to follow a

vegetarian diet to lower his or her fat and cholesterol intake.

The immorality of consuming animal flesh is another argument touted by a smaller group of vegetarians.

R.G. Frey describes this moral argument for vegetarianism and the effect that meat eating might have on

the character of humans:

Some people have come to believe and fear that, in the suffering and killing which occurs in commercial

farming, we demean ourselves, coarsen our sensitivities, dull our feelings of sympathy with our fellow

creatures, and so begin the descent down the slippery slope of torture and death, to a point where it

becomes easier for us to contemplate and carry out the torture and killing of human beings. (20)

This moral argument for vegetarianism is also noted by John Robbins who states that “the suffering

these animals undergo has become so extreme that to partake of food from these creatures is to

partake unknowingly of the abject misery that has been their lives”(14).

But whatever the reasons behind a person?s choice to be a vegetarian, it is important to understand the

different diets that individual vegetarians can choose. In the widest sense of the word, a vegetarian diet

is a diet that is made up of grains, vegetables and fruit, but does not include any animal flesh, such as

fish, pork, poultry, or beef. But beyond these standards, there are many variations of diet that occur

within the world of vegetarianism.

The first, and most prominent, category of vegetarianism is a lacto-ovo vegetarian. Mark Messina

describes a lact-ovo diet as “…a vegetarian diet (that) includes dairy products and eggs but no animal

flesh”(7). This means that there is consumption of animal byproducts, such as milk, eggs, or honey, but

there is no consumption of animal flesh. Another variation is the lacto-vegetarian diet that allows the

consumption of milk and other milk products, but does not include the consumption of eggs. And like

all vegetarians, these two groups do not consume fish, poultry, or meat (Messina 7).

Another category that vegetarians can fall into are vegans. The vegan diet is by far the most strict of all

the vegetarian diets. According to Mark Messina, “Vegans avoid meat, fish, poultry, dairy, and eggs.

There are many other foods that may not be acceptable to many vegans, however. Foods that involve

animal processing to any degree are often avoided”(11). This means that vegans can consume no

foods containing animal byproducts, such as milk, eggs, or honey. Being a vegan often dictates an

“animal friendly” lifestyle that, aside from not eating anything that came from an animal, also abstains

from buying or using products that were tested on animals or are made from animal hairs or skin, such

as leather shoes or belts (Messina 11).

A common misconception of vegetarians is that they are all a bunch of skinny, malnourished idealists

who live on plants and soy milk. And another, related common misconception is that a diet of meat is a

diet that builds strength. Professor Irving Fisher of Yale designed a series of tests in which he compared

the strength and stamina of meat-eaters against vegetarians, with three groups of individuals

represented: meat-eating athletes, vegetarian athletes, and sedentary vegetarians. His studies showed

that the average score of the two vegetarian groups was over double the average score of the meat

eaters, even though half of the vegetarians were sedentary people and all of the meat-eaters were

athletes. Fisher concluded that:

….the difference in endurance between the flesh-eaters and the abstainers (was due) entirely to the

difference in their diet…There is strong evidence that a … non-flesh … diet is conducive to

endurance.(206)

A comparable study was done in 1968 by a Danish group of researchers that tested a group of men on

a variety of diets, using a stationary bicycle to measure their strength and endurance. The group fed

their test subjects a diet that was comprised of mixed amounts of vegetables and meats for a period of

time before testing the men on the stationary bicycle. The average time that they could pedal before

muscle failure was 114 minutes. The very same group of subjects was then fed a diet that was

comprised of only meat, eggs, and milk for an equal amount of time, and then re-tested them on the

bikes. On this diet, their pedaling time before muscle failure dropped dramatically to an average of only

57 minutes. That same group of men was again fed a diet that this time was comprised entirely of

grains, vegetables, and fruits before once again testing them on the bikes. The lack of animal

byproducts didn?t seem to hamper their performance, as many people would have thought, and the

men were able to pedal an average of 167 minutes before muscle failure (Robbins 156).

But vegetarians are still often criticized by people who feel that vegetarians do not get enough minerals

and vitamins as a result of their limited diet. But vegetarian food is among some of the healthiest foods

available to mankind, and while there is no easy way to determine the extent to which a vegetarian diet

can influence the health of those that follow its guidelines, the evidence is very indicative that it may be

an important contributing factor. Registered dietitian Johanna Dwyer, of Tufts University Medical

School and the New England Medical Center Hospital, Boston, summarizes these benefits:

… data are strong that vegetarians are at lesser risk for obesity, atonic [reduced muscle tone]

constipation, lung cancer, and alcoholism. Evidence is good that risks for hypertension, coronary artery

disease, type II diabetes, and gallstones are lower. Data are only fair to poor that risks of breast

cancer, diverticular disease of the colon, colonic cancer, calcium kidney stones, osteporosis, dental

erosion, and dental caries are lower among vegetarians.(53)

Vegetarian diets contain less total fat and less saturated fat, which are linked to increased risk of

obesity, diabetes, heart disease, and cancer. In comparing the diets of vegetarians to omnivores, Mark

Messina indicates that “American omnivores eat a diet that is 34% to 36% fat, lacto-ovo vegetarians

eat a 30% to 36% fat diet, and vegans eat a diet that is about 30% fat” (59).This means that

vegetarians also consume less cholesterol, which has been linked to an increase in the risk of heart

disease and possibly even cancer. The amount of cholesterol of a lacto-ovo vegetarian is about 150 to

300 mg of cholesterol per day compared to the 400 mg of cholesterol that an omnivore consumes

(Messina 59). Vegans, who exclude the intake of any food that contains animal byproducts, do not

consume foods that contain significant amounts of cholesterol. The US Department of Agriculture and

Health and Human Services have created a Food Guide to better advise Americans on how to eat

healthier, more balanced meals, and which “advises using fats, oils, and sweets sparingly” (Farley 52).

Vegetarians as a group also consume higher amounts of fiber. Fiber, found mainly in grain products, is

essential to healthy bowels and colons, lowers the risk for diabetes, helps control blood glucose levels,

and also lowers the risk for cancer and heart disease (Messina 59). And it is grain products that form

the base of the U.S. Department of Agriculture and Department of Health and Human Services? Food

Guide Pyramid, which recommends servings of bread, rice, cereal, and pasta 6 to 11 times per day.

(Farley 52) The typical intake of fiber for an average omnivore is “about 12g of fiber each day,”, with

vegetarians eating “50% to 100% more fiber than nonvegetarians” (Messina 59).

A vegetarian diet also includes consumption of more antioxidants, which are believed to reduce the risk

of cancer, heart disease, and possibly arthritis and cataracts. Dietary antioxidants include such vitamins

as vitamin E, vitamin C- of which the typical vegetarian diet includes 50%, 100%, or even higher- and

carotenoids as well as the many phytochemicals that are found in plants (Messina 59). They also

consume less animal protein, with omnivores consuming 14% to 18%, lacto-ovo vegetarians consuming

12% to 14%, and vegans consuming only 10% to 12% (Messina 59). While vegetarians consume less

total protein, they do consume adequate amounts to maintain a healthy balance, as demonstrated by

modern nutritional science. Excess protein, and in particular excess animal protein, is linked to the

increased risk for osteoporosis, kidney stone formation, kidney disease, and an increase in blood

cholesterol levels (Messina 59).

The nutritional benefits of a vegetarian diet very clearly appear to be beneficial to human health. But a

vegetarian diet can also be healthy to the lives of our planet?s other inhabitants, the very animals that

are being eaten. Due to the increased demand for food, livestock farmers have had to keep up by

devising new and more efficient ways to raise more animals, giving way to the industrialization of meat

farming. As John Robbins accurately writes, “the raising of chickens in the United States today is not,

however, a process which overflows with compassion for these animals” (52). Chickens, as we grew

up believing, were farmyard animals that would root around in the soil for their food, and were deeply

attuned to the cycles of nature, as evidenced by the rooster crowing at the break of day. But the

industrialization of chicken farming in the past forty years has changed all this, and the days of the

barnyard chicken are over, replaced instead with what Robbins refers to as “the assembly-line chicken”

(52).

But the poultry farmers are not alone in its industrialization. The beef, turkey, pork and other meat

industries have also had to adapt their methods of “production” in order to keep up with the demands

of omnivores. This includes the use of growth hormones in the animals to produce more eggs and fatter

animals, which are then passed on to their human consumers. John Robbins describes some of the

products used in today?s pork industry in his book Diet For A New America:

… will also be given products like the new feed additive from Shell Oil Company. Called XLP-30, it is

designed to “boost pigs per litter,” though it has a name that sounds like it should be added to motor oil

instead of animal food. Incredibly, a Shell official acknowledges- “we don?t know why it works.”

This is just one example of the chemical tampering that the meat industry is forced to do with its animals

in order to fight off the diseases that the animals? cramped, unsanitary living conditions bring with them.

As discussed by R.G. Frey, this poses the most serious of threats to the health of Americans because

“…the liberal use of antibiotics in animal feed may, in time, build immunity in animals and, through them,

in us, to these drugs, some of which may play a role in the treatment of human diseases” (10).

Leonardo Da Vinci said “the time will come when men such as I will look on the murder of animals as

they now look on the murder of men” (Robbins 148). While the cruelty of murdering other animals for

their flesh is a moral argument in favor of vegetariansim, it seems rather unlikely that amny Americans

could ever be swayed by its message. However, many Americans are interested in preserving their own

health and well-being, and that should lead many people towards a vegetarian lifestyle since a

vegetarian diet includes the necessary vitamins and minerals to sustain human life, with out any of the

negative byproducts of animal consumption, such as cholesterol, excessive fat, and excessive protein. A

healthy lifestyle is something benefits us all, and yet most people are unwilling to give up the meat-filled

diets.

If the phrase “You are what you eat” has any amount of truth to it, then Americans need to realize what

they are ingesting every time they enjoy a Big Mac, some Whoppers, or a filet mignon. There are

healthier alternatives to the meat eating that nearly every member of our society has been weaned on,

and those alternatives all include the consumption of more vegetables and the absence of meats. It is

now up to them to realize this and make the necessary adjustments.
