Late 20th Century developed
world • Epidemiological revolution: longer life and death
from degenerative diseases: shift to long-term consequences
• food surplus
• extraordinary range of food choices
• development of super-foods (e.g. chocolate)
• no work needed to attain choices
• massive amounts of risk information
• no training in dealing with risks/benefits

Background Confluence of factors:
• Extensive qualitative and ethnographic evidence for the
multiple meanings that food holds for people.
• Historically, our relationship to food was laden with
meanings that figure importantly in our moral, symbolic,
social, and ecological worlds.
• Even in the current global food system, there are stable
cross-country differences in how people relate to their food,
oft tied to the worldview and value system of a unique
culture.
• In the health behavior and nutrition literatures, these
meanings have not been operationalized for empirical
investigation
• Typically use rational, cost/benefit analyses and expectancy
value theories that have only moderate explanatory power
• These theories, such as the Theory of Planned Behavior,
have now started to measure constructs such as moral norms
• The mechanisms wherein these norms take hold, become
internalized, and spread are poorly understood
Background
Rationale
• The current food environment is undergoing
change
• Similarly to what happened with tobacco
smoking, we are seeing broad scale changes in
awareness and moralizing of food issues
• Tobacco smoking declined following
moralization, rather than following
interventions based on health risk information
Rationale • Food is coming to take on different meanings to a degree
unseen in prior generations
• People are focused on:
- clean/pure foods
- green/natural foods
- ethical and artisanal foods
• The new omnivores dilemma & spheres of moral concern
expanding to encompass environmental, animal welfare
and humanitarian concerns
• How to measure?

Research Aims
• To operationalize the meaning of food in life for empirical
investigation
• To develop and validate a comprehensive measure to assess
the different domains of meaning that food holds for people
• To understand a new determinant of health behavior, and
investigate its association with:
• Dietary intake patterns
• Local and organic purchasing decisions
• Willingness to Pay to ensure socially responsible
outcomes
Theoretical Background: Meaning
• Stable, higher-order, abstract construct that involves
making connections between and integrating events and
experiences into a larger and coherent sense of order.
• Involves an understanding of one’s self + one’s world
(lifeworld), as well as one’s role in the world.
• Also encompasses a motivational drive towards
purposive activities congruent with this larger cognitive
framework.
• Criterion for meaning classification: “If an action is meaningful, it is included into the meaning web and thus finds a place in the whole person’s life-world, rather than in the demands of the situation.” (Leontiev, 2013)
• To what degree are people making food decisions from the perspective of their life-world?
From Meaning to the Meaning of
Food in Life (MFL)
The Meaning of Food in Life (MFL)
• The meaning of food in life represents the degree to which people see
their food/eating experiences as having significance beyond the
immediate demands of the situation and as connected to their larger
life-world.
• Explicitly involves a cognitive connection made between people’s
food intake and non-immediate aspects of the eating situation –
contrast with immediate and hedonic orientations to food.
• More than the satisfaction of momentary preferences. Can be
connected to larger life goals. In most cases, will involve a connection
between food intake and non-food related aspects of life.
The Meaning of Food in Life
Questionnaire (MFLQ)
• Our research team generated a final set of
22 items based on:
– Analysis of qualitative responses in 2 pilot
studies
– Four iterative rounds of data collection with
exploratory factor analyses
MFL Data Collection Process
Exploratory Study
• Initial N = 151
• Final N = 142
Empirical Study 1
• Initial N = 254
• Final N = 228
Empirical Study 2
• Initial N = 252
• Final N = 221
Empirical Study 3 + Retest
• Initial N = 226
• Final N = 197
Study participants recruited via Mechanical Turk in USA
MFLQ Results
• The results of the exploratory factor
analyses showed a 5-factor structure which
cohered consistently across all 4 empirical
studies
MFL Factors & Sample Items
Moral
• When I eat food I think about where it came
from
• I eat in a way that expresses care for the
world
• My food choices reflect my connection to
nature
Social
• Food is closely tied to my relationships with
others
• When I eat I feel connected to the people I am
eating with
• Food is a way for me to connect with my
cultural traditions
MFL Factors & Sample Items
Aesthetic
• Preparing a good meal is like making a work of
art
• Eating a good meal is an aesthetic experience
like going to a good concert or reading a good
novel
• I can appreciate the beauty of a dish even if I
do not like it
MFL Factors & Sample Items
Sacred
• What I eat is a reflection of my spiritual beliefs
• From a spiritual perspective some foods are
better than others
• My food choices are a way for me to connect
with the sacred
MFL Factors & Sample Items
Health
• I get satisfaction from knowing that the
food I eat is good for my health
• I feel that nourishing my body is a
meaningful activity
• I eat in a way that expresses care for my
body
MFL Factors & Sample Items
MFLQ Results
• Test retest reliability (measure of stability
of score over time) was high (r > .8)
• Displayed consistently significant
associations with patterns of dietary intake,
purchasing habits and willingness to pay
(WTP)
• Dietary intake measured w. validated questions from
NHANES dietary screener questionnaire (DSQ;
Thompson et al, 2004.)
• Participants asked how frequently they consumed the
following foods in the past 30 days: fruit, vegetables, red
meat, processed snacks and junk food.
• They responded using a 10-point scale ranging from
‘never’ to ‘4+ times per day’.
• Participants also asked self-reported behavior: “I limit
my intake of fast food” and “I substitute meat with meat
substitutes when possible”

Summary & Conclusions
• The MFL is a valid and new construct for
assessing the meaning of food in people’s lives
• The different domains of the MFL are health,
moral, sacred, aesthetic and social
• These domains display different associations
with dietary intake patterns, organic and local
food purchasing behavior, and willingness to
pay higher prices for socially responsible
outcomes
Eating as social: Sharing food enhances the
experience; It is important for me to sit down and
enjoy a meal with family and friends
Role of religion: Eating is a religious experience;
My diet must adhere to strict moral/religious
principles
