The document discusses the impact of human diet on sustainability. It argues that an optimal diet from a sustainability perspective is locally grown, organic, and plant-based. Such a diet reduces carbon footprint and environmental impact while supporting health and local economies. It notes the large role agriculture plays in economies and environmental issues like greenhouse gas emissions. Industrial agriculture relies on monocultures and heavy use of chemicals, while organic farming is better for the environment, soil health, and nutrition. Choosing local, organic, whole foods and cooking at home can significantly improve health and sustainability.

The Human Diet and Sustainability
Frazier Thurman
Winter 2016
A study of the impact of human diet on current economics, the environment,
human health, and global social conditions.

Introduction
This paper will focus on what many industry leaders consider is the “optimal” human diet by
way of reducing our carbon footprint, conserving and preserving natural resources, beneficially
contributing to human health, and creating safe healthy jobs that support economic viability.
I will discuss how food choice and food production affect many aspects of sustainability and life.
The optimal human diet is not a single idea on its own self sustaining. Human diet has many
impacts in the natural world and is impacted itself by many processes. This paper will attempt
to bridge the gap between health and nutrition and consequence of choice.
I will reference many sources. I will use books, scientific studies, peer reviewed journals,
personal interviews, and documentaries to support that organic, locally grown and produced,
plant based diets are optimal.
I invite you to embrace and enjoy this paper and to look with an open mind at your own
behavior and change as much or as little as you can.
“I am only one, but I am one. I cannot do everything, but I can do something. And because I
cannot do everything, I will not refuse to do the something that I can do.”
― Edward Everett Hale
*Note, the author believes this diet and lifestyleis optimal for consumers where all categories and conditions
apply.Such diets may not be possiblein all places around theworld, and for all communities .

Agriculture and Economics
Food production is one of the major industries of the world; the Food and Agriculture
Organization of the United Nations states that global food production worldwide annually is
over 100trillion US$(4). The economic impact of the industry alone is massive and has the
potential to support or suffocate many regions. The US is the top exporter of agricultural
products at 395bill$ in 2012(11). The figure below from the USDA Ag census shows how many
farms and regions in the US make over 30mil$ annually.
More than 2 million people in the US claimtheir primary occupation is farming (4). This
statistic doesn’t account for migrant workers, seasonal laborers, or family members related to
farmers performing farm work. North Carolina State University (5) reports that 22 million
people in the US work in some capacity related to food production, processing, and sales. At
Figure 1: From USDA Ag Census Website
4. 4
less than 2% of the total US population, these employees are working very hard to produce
approx 2000lbs of food per person in the US annually (7).
Food and Farming job security is much lower than in traditional desk jobs. Typically workers
have to follow (8) crop work and do not have guaranteed positions year round. In 2001-2002,
53% of the hired agricultural labor force lacked authorization to work in the United States (12).
Farming is a temperamental business. These numbers and available products can fluctuate
daily/weekly/monthly as determined by ecosystemhealth, weather, political climate, disease
and pests, and global climate change.
Observing these numbers can help us understand the importance of food, food production, and
agriculture. I’ve stated this introductory information near the beginning to help the reader
begin to imagine the repercussions and consequences of mass food production. My hope is that
as you read this paper you will become more aware of how your food decisions affects the
local, regional, and global economy. Consumption choices affect nearly all of the information
given above, especially in relation to individual energy and resource consumption. Often it is
overlooked the effort assigned to producing a single serving of food, this paper and it’s data
should help individuals grasp this concept in terms of sustainability in society, economics, and
environment.
Conventional and Organic Food Production
Farming has long been considered the job of environmentalists; a traditional picture of people
and families who steward the land, cultivate the soil, and care for animals. But as technology
5. 5
has evolved and demand for more food at lower prices has increased; the face of farming has
changed. Industrial Agriculture has taken over inducing large farms of 400+ acres of mostly
cattle, dairies, corn, and soybeans. “In 1900, the average farm size was 147 acres, compared to
441 acres today. Farming and food production utilize nearly 50% of all habitable land in the
world”(9). The top five agricultural commodities are cattle, dairy products, broilers
(chicken), corn and soybeans. U.S. farmers produce 46% of the world's soybeans, 41% of the
world's corn, 20.5% of the world's cotton, and 13% of the world's wheat (14). Corn is the top
agricultural commodity in the US and sold up to 67bill$ in 2012(11). *Note this statistic does not
include the govt. Ag subsidies for unsold commodity corn.
Currently corn is mostly grown in huge monocultures using herbicides, pesticides, and GMO or
treated seeds. Many scientists and real life industries have proven that monocultures severely
destroy native ecosystems. They remove native plant and animal species, as well as habitat, and
disrupt the natural ecosystem cycle by outcompeting for resources or displacement. Currently,
almost every day we lose about 80,000acres of tropical rainforest to industrial Agriculture
worldwide (13).
Another issue with monocultures is that typically they are run until they cannot produce
anymore, such that desertification takes place. As much as 12 million hectares are lost
worldwide to desertification each year (11). The result is land that is non-arable and desolate.
That may have once been a nourishing native prairie now a cracked desert wasteland.
Huge amounts of chemicals in forms of fertilizers, soil conditioners, and pesticides have to be
used to grow non-native crops in such giant amounts. Over the last 30 years alone, more than
6. 6
90% of arable farmland in the world has been treated with agrochemical pesticides (10).
Pesticide usage has declined, yet herbicide usage has increased significantly during the same
period. “In 2007, the U.S. agriculture sector used 877 million pounds of pesticides (12).”
When ecosystems and habitats are destroyed, soil health is negatively impacted. Soil that is
unhealthy, compacted, or has been heavily eroded from too much tillage cannot be penetrated
by these chemicals and so you end up with the problem of runoff. Runoff is any applied
products that do not penetrate the soil and that are washed or swept away by wind, water,
animals, and natural occurrences to anywhere else (18). Runoff leads to issues like ocean
eutrophication; ocean dead zones like that in the Gulf of Mexico, polluted water resources,
contaminated soils, and hazardous bio-wastes.
Organic Agriculture is limited to a few natural fertilizers and chemicals as described by the
National List under the National Organic Program (22). Due to these contentions organic farms
tend to employ more people, grow more diversity on a single farm, and grow equal amounts of
food matter per acre (23).
In accordance with Organic food handling requirements, these food products must be kept
separate from conventional products and labeled as such (22). Organic crops have been tested
in many studies and actually show them containing more nutrients than conventionally
produced crops and less likely to carry harmful toxic substances (24).
From my experience studying Horticulture at OSU and being involved in the community, I’ve
had the pleasure of meeting and exploring many local organic farms and orchards. All of them
7. 7
have diversified interests. Not even a single farm I’ve visited on those trips were monoculture
growing environments; further perpetuating that organic growers contribute more by way of
soil rejuvenation and conservation of resources than conventional growers.
The Co-Operative Experience
First Alternative Co-Op was founded in 1970 out of a small house in downtown Corvallis. It
began as a store share where members could order bulk products together that they could not
otherwise find in the city. It evolved into a South town storefront where not only members, but
the public could also shop to find natural and organic brands and produce. Since then First Alt
has opened a second store, created a board of directors and joined the Natural Cooperative
Grocers Association to combine forces and impact change throughout the region and the
country. The co-op is an interesting place where on any given day you may find OSU footballers
purchasing party pigs, townies shopping the u-grind peanut butter, or out-of-towners getting a
snack from the deli salad bar.
The co-op is a Mecca for diversity; especially in products. We carry fair trade, Rainforest alliance
certified, Vegan, Gluten free, Organic, Local, Paleo, Dairy free, Soy free, and many other natural
products; mostly determined by our board of directors, our members, and customer
comments. We have most departments a standard grocery store would have including:
Grocery, Bulk, Dairy, Chill, Meats, Deli, and Produce.
The emphasis of the co-op however is that we cooperate with our community, employees, and
members to create the vision that best suits all. First alternative is increasingly concerned with
8. 8
sustainability efforts and has many employees on the Corvallis Sustainability Coalition. We also
use solar panels and grey water recycling systems within the store. We focus on purchasing and
selling products that are ethically sourced and produced.
Perhaps the greatest thing, of which I enjoy most, about being a part of the co-op community is
the environment of ideas and creativity that are nurtured here. Co-Op members and staff share
ideas and information together in a protected space and creativity can flourish. It is here that a
lot of my food production and diet related ideas were both confirmed and challenged.
In my position of a produce stocker, I have had the absolute pleasure of working with large
scale organic farmers, local food producers, and organic wholesalers alike. The produce
department orders from a variety of these and tries its best to support local and organic
farmers. A key characteristic of produce and the store itself is that product origin is emphasized
as to be completely translucent with the customers. In produce, each sign has the origin printed
on it offering some of the back story to the public. The Produce team periodically takes field
trips to local farms where we source some of our produce. Here is where we get to see
firsthand, and subsequently share with the community, the processes we are purposefully
supporting.
The Local Food Movement
One such idea that is particularly important to food co-ops is supporting local business.
Nowadays, most people and politicians are concerned about reducing the carbon footprint that
we all have. Many people consider transportation the largest impact area. The largest impact
9. 9
area may actually be food. At a contributing 17% (16) of a person’s total carbon footprint the
kind of food, location originated and purchased from, and packaging contribute to the overall
‘foodprint’.
Locally purchased food means that it originated from the same area it was sold in. Typically a
store or community will define ‘Local’ by counties, or miles the product may have travelled. In
Oregon, we’re really lucky because we essentially live in a food paradise. At any time, I can
purchase any number of sodas, bread, beer, wine, desserts, rice, grains, fruit, vegetables,
canned goods, and even prepared foods made of solely locally grown foods. This mostly is not
true for citizens of other regions or climates. However that does not change my belief and the
science that locally grown and sold food has a lower carbon footprint than mass produced and
transported food items.
A huge dietary benefit of eating locally sourced whole foods is that the food retains more of its
original nutrition. Due to the simple fact that it did not (typically) go through a freeze and thaw
cycle, and it will (typically) be consumed closer to the date it was harvested. Local food is
fresher and more than likely more healthful for those of us that can get it.
Purchasing locally grown or produced is in effect a way to support your community and
ultimately yourself. The money spent within your community circulates and is spent more
wisely than at a global scale. If you track a dollar spent at a farmers market, or a food co-op you
may find that it is much more likely to remain in the community for longer than money spent at
large corporate food stores.

Where you get your food is not the only determinant of its foodprint. There are other
considerations that affect the energy used to produce, transport, and sell food products.
It’s not you; it’s Meat.
..and it’s so much more than meat. The Agri-lobby has found a way to process pretty much
every food type that you may buy today; from sweeteners, to artificial flavors and colors, meat
and dairy products to food additives or preservatives (17) (20). But meat may have the best
case for the worst kind of food. Confined Animal Feeding Operations are the most commonly
used model to produce large amounts of meat and dairy without spending large money. CAFO’s
are essentially animal feedlots where there has been documented criticism of animal welfare
and treatment as well as waste disposal and pollution issues, obtuse water mismanagement
problems, and general unpleasantness (18).
Anyone familiar with CAFOs probably knows that the feed used in these conditions is less than
ideal. “Less than ideal” in this case is a gross overstatement. Most corporately managed animal
facilities use antibiotics, spent grains, and even recycled animal products to fatten up animals in
a shorter time with less expensive inputs (18).
There are more than a dozen plant based foods that supply more protein per serving than meat
along with fiber and other phytonutrients that meat does not have. Below is a table
representing various plant based foods that deliver powerful protein in a punch!

Get back in the kitchen!
“A true key to good health is to own a pan and a spatula.” –Anonymous
Indeed, learning how to cook may have the largest impact on community health than even
exercise and nutrition education (20). The decline of a home cooked meal began around the
time of World War 2, when both
parents of a family where working
to support the war effort (25). A
new product arose out of the war
machine: “convenience foods”
Meals that were based in corn and
starch, in single serving or family
packages that could be easily
slipped in to the oven or
microwave a few minutes ahead of
diner time.
Agri-business and the government
(who was subsidizing this
development during and after
WW2) suggesting mass marketing convenience foods to the public. These foods were originally
designed for deployed war rations and are the original American TV dinner.

Today we are facing an epidemic of unhealthy and overweight people. Check out this statistic,
“The average American consumes about 23 teaspoons of added sugars and sweeteners per day;
the American Heart Association recommends between 5 and 9 teaspoons daily for an average
adult. More than 68% of U.S. adults are overweight or obese (body mass index 25+), and 17% of
children age 2-19 are obese (12) (21)”. Diet contributes to heart disease, certain cancers, and
stroke—the three leading causes of U.S. deaths (12).
Many health problems today are diet-related and may be simply eliminated by removing
processed foods from the diet (21). If you can cook at least 90% of your meals at home
centered on whole ingredients; you will be doing yourself a huge favor. Food is nutrition,
nutrition is medicine. Therefore “Let food be thy medicine” – Hippocrates.
Perspectiveand Conclusions
My experience of having worked at the Co-Op in Corvallis, studying food personally, studying
agriculture and sustainability at OSU has led me to believe a few statements.
The first is that Agriculture has the largest impact on each person’s carbon footprint and the
decision is enhanced by their diet. Products we choose to buy and consume determine the
amount of energy spent and emissions produced. Organically grown and produced food should
be priority over conventional because of this foodprint and health concerns.
Second, that in order to foster a sustainable future, we must purchase and consume in a
specific way. Food should be purchased locally, or have travelled the least amount of miles and
13. 13
be minimally packaged. Local food not only provides cash flow to a community but also
negative energy consumption by way of fossil fuels.
Third; to achieve optimal health and nutrition from diet we must eat whole foods and have
meals be plant based. We can no longer ignore the science that processed foods are poisoned,
making us sick, and in many cases killing us. Those foods high in fat and sugar are not our allies.
Nutrient dense foods like who grains, vegetables, and legumes should be center at the
breakfast, lunch, and dinner table. There are many ways to eat; there are many things to eat.
But there is only a few ways to achieve optimum health through diet; a healthy diet is
composed of whole foods and is plant based.
