Background and Objectives: An individual’s liking for food maybe associated with food consumption. This
study investigates the association between food liking and dietary quality in Australian young adults. Methods
and Study Design: Food liking and food frequency data were collected via an online Food Liking Questionnaire
(FLQ) and Food Frequency Questionnaire (FFQ). Food liking scores were calculated for groupings of foods. FFQ
Food intake data was used to calculate diet quality using a 13 item Dietary Guideline Index (DGI). The relationship between food liking and DGI was assessed using linear regression models and the difference was assessed
using an independent sample t-test and One-way ANOVA. Results: Data were available from n=2,535 participants (BMI=24 (SD 3.74), age=21.9 (SD 5.05) years, female=77.1%). Liking for grains, vegetables, fruits, dairy,
plant-based protein, was weakly positively associated with diet quality. Liking for animal-based protein, fat and
oil, sweet food, and salty food, was weakly negatively associated with diet quality. Liking for grains, vegetables,
fruits, dairy, plant-based protein and healthy foods increased across increasing DGI tertiles, and liking for animalbased protein, fat and oil, sweet food, salty food and discretionary foods decreased across increasing DGI tertiles.
Conclusions: The results were logical with increased liking for healthy or discretionary foods linked with increased consumption of those foods. The results reinforce the strategy to introduce a variety of healthy food
groups early in life to initiate flavour-nutrient learning and increase liking for healthy foods.

INTRODUCTION
Food liking is the perceptual outcome which combines
the flavour of a food, previous experiences with the food,
health state all of which make an individual’s response to
food is multi-dimensional and dynamic.1 These factors
may influence liking decisions at any point in time.2 The
liking of a food’s flavour is an important driver of shortterm food consumption and energy intake, as those who
enjoy the flavour of the food they are consuming tend to
eat more of it.2-7
Flavour is a psychological construct with the flavour
we experience from a food being a combination of inputs
from the five classic senses: taste, smell, touch, sight and
hearing. There is large inter-individual variation in each
of the senses and as they each have inputs into the perceived flavour of a food, each individual experience flavour from a food that are unique to that individual.8-11
Food flavour is also indicative of the nutrients found in
the food consumed and has an important influence on
food choice.4,7,12-15 For example, sweet taste may indicate
energy and carbohydrate content, umami and salty tastes
may indicate protein and sodium content respectively and
all three qualities are appetitive and encourage consump-
tion.12,13 Energy imbalances due to overconsumption of
food is common, especially given discretionary foods
high in palatable fat, sugar and salt.16-20 Food liking has
been observed to be a driver of food consumption and
may in part be responsible for determining diet quality
and excessive energy intakes.
Obesity represents the largest preventable disease
worldwide and is a contributor to ill-health outcomes including cardiovascular disease, stroke, type 2 diabetes,
hypertension, arthritis, respiratory disorders and certain
cancers.21 Whilst the causes of obesity are multi-factorial
and complex, they are embedded within energy imbalances brought about by psychological, cultural, personal,
environmental, lifestyle, and dietary factors which favour
excessive energy intake coupled with sedentary behavCorresponding Author: Dr Russell SJ Keast, Centre for Advanced Sensory Science, Deakin University, 221 Burwood

Food liking and the dietary quality in young adults
iour.22
Given that an improvement in dietary quality may lead
to an improved quality of life.23-25 it is useful to explore
the relationship between food liking and diet quality. The
association between food liking and dietary quality was
reported by Zoghbi et al and Sharafi et al26,27 and the
study found that the healthy dietary quality correlated
with liking and intake of a healthy foods. A study by
Duffy et al28 demonstrated that the liking of fatty foods
was positively correlated with fat intake. Further, a positive relationship between the liking for fatty foods, body
weight and systolic blood pressure was found. This relationship between food liking and dietary intake was also
observed in a large study by Mejean et al which found
that those with a higher liking for fatty foods had an increased intake of total energy, fat and certain foods (high
in fat) such as meat, butter, desserts and pastries, and a
positive relationship between the liking for fatty foods
and obesity risk was observed.29
The aim of this study was to determine the relationship
between food liking and dietary quality in Australian
young adults. The Dietary Guideline Index (DGI)
measures how well an individual achieves the recommended number of servings for each of the recommendations within the Australian Dietary Guidelines. It was
hypothesised that the liking of a food will be a factor influencing the dietary quality in Australian young adults.
METHODS
Participants and procedures
Participants were undergraduate students enrolled in a
first-year food and nutrition subject at Deakin University.
Data collection occurred during 2015-2018. Participants
completed the questionnaires as part of their assessment
tasks for the subject, and after completion of their assignments they were invited to provide consent to allow
the data to be used for research purposes. Ethics approval
was obtained from the Human Research Ethics Committee at Deakin University (HEAG-H 163_2009) and all
participants who agreed to participate in the study provided written informed consent.
Food liking questionnaire
The FLQ and subsequent Food Liking Score has been
previously described.30 In brief, the FLQ used was a
modified version of a FLQ from Duffy et al28 which was
adapted for culturally relevant Australian foods. The
questionnaire contained 73 food items and measured liking using a nine-point hedonic scale. This scale consists
of a series of nine verbal categories representing degrees
of liking from ‘dislike extremely’ to ‘like extremely’. For
subsequent quantitative and statistical analysis, and all
verbal categories were converted to numerical values:
‘like extremely’ was coded as ‘9’, ‘dislike extremely’ as
‘1’. FLQ contained the instruction “if you have never
eaten a particular food, or never experienced one of the
listed items, please rate the item as ‘neither like or dislike”. Food items within the FLQ were classified into 10
main categories based on the Australian Guide to Health
Eating: grains, vegetables, fruits, dairy, animal-base protein, plant-base protein, fat and oil, sweet food, salty food,
and alcohol Food liking scores were generated for each
167
food grouping and the groups grains, vegetable, fruit,
dairy, animal-base protein, plant-based protein, fat and oil
groups were further combined to generate a healthy group
and sweet food, salty food, and alcohol groups were combined in a discretionary group.23
Food frequency questionnaire
An adapted version of the 1995 Australian National Nutrition Survey FFQ.31 was used to measure each participant’s habitual pattern of food intake. Participants were
required to indicate, on average, how many times in the
previous month they consumed a number of food and
beverages and vitamin and mineral supplements (118
items; bread and cereal foods, dairy foods, meat, fish,
eggs, sweets, baked goods, and snacks, dressings, nondairy beverages, vegetables, fruits). Participants were
instructed to select the most appropriate answer on a ninepoint scale with response options ranging from “Never, or
less than once a month”, “1-3 times per month”, “once
per week”, “2-4 times per week”, “5-6 times per week”,
“once per day”, “2-3 per day”, “4-5 times per day” and
“6+ times per day”
Diet quality assessment
The Diet quality of participants was assessed using data
from FFQ and a previously developed Dietary Guideline
Index (DGI).32 Dietary information collected from the
FFQ was used to assess the diet quality using a 130-point
diet quality index for each participant. The DGI is comprised of thirteen components with each component having a maximum possible score of 10 points, a higher DGI
score reflects a better diet quality.32 The thirteen components of the DGI are set to assess a participant’s intake of
key nutrients from core food groups, the proportion of
key nutrient intakes from healthy food types (e.g., lean
meats or wholegrain cereals), variety of foods in the diet
and intakes of unhealthy foods. Those that reported to be
in between the criteria for minimum and maximum had
scores proportionately adjusted; for example, if a participant reporting consuming one serve of fruit (half the recommended amount as per day in the 2013 Food for
Health Guidelines within the Australian Dietary Guidelines)23 they received a score of 5 for that component—
half of the maximum possible score. This method of diet
quality assessment has been previously validated; a higher DGI score has shown to be inversely related with poor
health outcomes in previous research.32
Statistical analysis
Statistical analyses were carried out using SPSS version
25.0 (IBM Corporation, Armonk, NY, USA). Cronbach’s
Alpha was used to determine internal consistency of the
liking score for each food group. The Cronbach’s alpha
values were interpreted as unacceptable (<0.50), poor
(0.51-0.60), questionable (0.61-0.70), acceptable (0.710.80), good (0.81-0.90), and excellent (0.91-1) (Table
1).33 Relationships between food liking and DGI was assessed using linear regression models accounting for BMI
and gender. Regression beta coefficient (β) and 95% confidence interval (CI) were reported. Eta-square effect size
(η2) was calculated for multiple regression to determine
magnitude of the associations. η2 was interpreted as small

(<0.02), medium (0.02-0.13), and large (>0.26).34 Independent sample t-test was used to compare the food liking
groups between genders. Chi square test was used to
compare BMI categories across gender. A value of
p<0.05 was considered statistically significant. One-way
ANOVA was performed to compare food linking with
BMI categories follow by Post-Hoc comparison, Bonferroni method was used to account multiple comparison.
RESULTS
Participant characteristics
From the n=2,657 participants that were initially available,
n=122 participants were excluded as they did not answer
the self-reported weight and height questions, or provided
unusual data (BMI lower than 14 and over than 50) or had
incomplete data (Incomplete FLQ – defined as missing
any liking rating for any food or beverage item), leaving
the total number of participants as n=2,535. The mean age
was 21.9 (±5.05) years. The majority (77.1%) of the participants in this study were female. The average of Body
Mass Index (BMI) was 24 (±3.74). Thirty-three percent
(n=848) were overweight. See Table 2 for the complete
demographics.
Linear regression analysis was used to investigate the
association between food liking groups and diet quality as
measured by the DGI. The effect size estimates for multiple regression for the association between food liking
groups and DGI were small for all of food groups (<0.02)
(Table 3).
The liking score for grain, vegetable, fruit, dairy, plantbased protein, and healthy groups showed statistically
significant positive associations with DGI score. Thus, an
increased liking of grain (β = 2.45, CI [1.90, 3.00]), vegetable (β=1.17, CI [0.62, 1.72]), fruit (β=0.92, CI [0.28,
1.55]), dairy (β=0.48, CI [0.17, 0.79]), plant-based protein (β = 0.99, CI [0.61, 1.37]), and healthy groups
(β=1.06, CI [0.32, 1.80], was associated with an increase
in DGI score. For animal-based protein (β=-0.42, CI [0.73, -0.11]), fat and oil (β=-0.88, CI [-1.28, -0.47]),
sweet food (β=-1.01, CI [-1.43, -0.60]), salty food (β=0.86, CI [-1.30, -0.43]), and discretionary groups (β=-1.17,
CI [-1.67, 0.68]), an increase liking was associated with a
decreased DGI score (Table 3).
Linear association was used to examine food liking and
DGI scores separately for males and females. For males,
the liking score for grain had a positive statistically significant association with a higher DGI score (β=2.56, CI
[1.28, 3.85]). An increased liking for fat and oil (β=-1.34),

Comparing food liking between DGI categories
One-way ANOVA were used to compare the mean dif-
170
U Wanich, L Riddell, S Cicerale, M Mohebbi, D Sayompark, DG Liem and RSJ Keast
ferences of food liking between DGI tertiles (Table 4).
Bonferroni method was used for accounting in Post-Hoc
comparisons. Significant differences (Bonferroni adjusted
alpha=0.01) were observed for Post-Hoc comparison
across DGI tertiles for all food groups.
The mean difference of food liking between DGI tertiles was statistically significant for all of food groups:
grains, vegetables, fruits, dairy, animal-based protein,
plant-based protein, fat and oil, sweet food, salty food,
healthy food, and discretionary food (p<0.01) except alcohol. There was a significant increase in liking of grain
(p<0.01), vegetable (p<0.01), fruit (p<0.01), diary
(p<0.01), plant-based protein (p<0.01), and healthy food
(p<0.01) across DGI tertiles, participants with a high DGI
score participants rating liking higher for these food
groups than participants with a lower DGI score. Conversely liking for animal-based protein (p<0.01), fat and
oil (p<0.01), sweet food (p<0.01), salty food (p<0.01) and
discretionary food groups was higher for participants with
a low DGI score compared to participants with a high
DGI score.
Comparing food liking and DGI score between BMI
categories
One-way ANOVA were used to compare the mean differences of food liking between BMI categories (Table 5).
The Bonferroni method was used for accounting for multiple comparisons in Post-Hoc comparisons. Significant
mean difference (p≤0.008) were observed for Post-Hoc
comparison across BMI categories for all food groups.
The mean difference of food liking between BMI categories for all participants was statistically significant in
six food groups: animal-based protein, plant-based protein, fat and oil, sweet food, salty food and discretionary
food group. There was a difference between participants
of a healthy weight and those overweight, in the liking of
plant-based protein (p<0.001) with healthy weight participants rating their liking of that food higher than those
overweight participants. There was a significant difference of liking of animal-based protein (p<0.001), fat and
oil (p<0.001), sweet food (p<0.001), salty food (p<0.001),
and discretionary food (p<0.001) groups with overweight
participants rating liking higher than healthy weight participants.
The mean difference of food liking between BMI categories in female participants was statistically significant
in seven food groups: animal-based, plant-based protein,
fat and oil, sweet food, salty food, alcohol and discretionary food groups. There was a difference between participants of a healthy weight and those overweight, in the
liking of plant-based protein (p<0.006) with healthy
weight participants rating their liking of that food higher
than those overweight participants. There was significant
a difference in liking of animal-based protein (p<0.002),
fat and oil (p<0.001), sweet food (p<0.001), salty food
(p<0.001), and discretionary food (p<0.001) groups with
overweight participants rating their liking higher than
healthy weight participants. There was no difference of
food liking and BMI categories in male participants for
all of food groups.
DISCUSSION
The association between food liking and dietary quality
intake in Australian young adults was explored in the
present study. As hypothesised, a higher liking for
healthy foods (as indicated by a higher food liking score)
was associated with higher diet quality, and a higher liking for discretionary foods was associated with lower
dietary quality. These associations were observed in both
males and females.
One of our primary findings was a significant difference in food liking between DGI tertiles for all of food
groups. The participants who had a higher liking for
grains, vegetables, dairy, plant-based protein, healthy
food groups had higher DGI scores than those in the low
DGI and average DGI tertiles. In simple terms, the more

an individual liked a food, the more of that food they consumed. As consumption of fruits, vegetables and
wholegrains are below levels suggested for optimum
health, developing strategies to increase consumption are
important for public health. One strategy that is likely to
be successful is flavour-nutrient learning through repeated exposure during childhood. For example, a study by
Lakkakula et al and Havermans & Jansen reported on the
repeated exposure of vegetable flavours during childhood
at school in the USA and the Netherlands.36,37 The results
showed that children improved the liking of vegetables
after repeated exposure to the flavour of vegetables. If
this increased liking is transferred through to adulthood
the results from this study indicate increased consumption
of vegetables. Furthermore, combined studies on healthy
food liking and dietary quality by Zoghbi et al and
Sharafi et al26,27 examined that those who had a high liking of healthy food including grains, vegetables and fruit
had a higher dietary quality and a lower BMI.
Liking of salty and sweet flavours can result in health
issues through the overconsumption of food high in sugar
and salt – often foods high in sugar and salt may be high
in fat and energy.2,23-25,28 Our studied found that participants who had a low DGI score had a higher liking for
animal-based protein, fat and oil, sweet food, salty food,
and discretionary food groups. Supporting this hypothesis,
Mela, Frehlich et al, and Maskarinec et al38-40 have observed that individuals who have a higher liking of high
energy foods such as animal-based protein, fat and oil,
sweet food, salty food, and discretionary food groups
consumed more of those foods. This higher intake of high
energy foods is at least in part likely to be driven by increased liking of this food group and linked to a poor dietary quality.
Gender differences in food liking and dietary quality
were observed in the current study. Females reported a
higher liking of healthy food groups and higher DGI
score compared with males. Female participants were
found to have a higher food liking score than the male
participants in the following food groups: grains, vegetables, fruits, and plant-based protein. In contrast, the males
had a significantly higher liking for dairy, animal- based
protein, fat and oil, sweet food, salty food, alcohol and
discretionary food. This observation is consistent with
previous publications. A study of Cooke and Wardle reported that young UK female participants had significantly higher liking for fruit and vegetables in comparison to
young male participants who had significantly higher
liking preference for fatty and sugary foods, meats, processed meat products, and eggs.41 It is potentially unsurprising as females have also been found to be more likely
to have concerns about health than men and this may
drive an increased liking for foods associated with
health.42 The current results, combined with those of
Ward et al, Alan et al, Arganini et al, Hiza et al, and
Guenther et al.43-47 indicate that females report a greater
liking for healthy food, experience high diet quality and
have a higher health attitude than male.
Post hoc analysis revealed differences in liking of food
groups between BMI categories. Overall a higher liking
for animal-based protein, fat and oil, sweet food, salty
food and discretionary food groups was associated with a
higher BMI. This is an intuitive finding supporting the
large French study by Deglaire et al and Lampure et al29,48
who reported a positive association between weight status
and liking of salt and fat in adult cohort, individuals who
have a high liking for salt and fat have a higher BMI. A
study by Pallister et al49 reported on the trends of food
preference patterns and BMI in a UK twin cohort with
higher liking for an animal-based protein pattern associated with a higher BMI. Appleton noted that frequency of
consumption of animal-based protein was also associated
with the liking of animal-based protein and a higher BMI
in a cohort from the UK.50 Multiple research studies of
taste and nutrients in food have found that taste of food
indicates the nutrient profile of the food, for example
sweet indicates a carbohydrate rich food and salty and
savoury indicate a protein rich food. Both sweet and salt
tastes are appetitive and drive consumption of food, this
can lead to higher intake of food and may increase the
risk of further weight gain especially if those foods have
high energy.5,12,13,51-57
The results of the present study add to the existing literature indicting that food liking is an important driver of
food choice and consumption,2-7,58 and can influence
BMI.16-20 Several studies have observed that participants
who are focused on the flavour of food and are less motivated by health concerns will make unhealthy food choices.59-61
The present study has limitations that should be noted.
Results for Grains, plant-base protein, fat and oil is presented for exploratory purpose due to poor internal consistency. The study populations are restricted to young
adults attending university and may not be representative
of the broader young adult Australian population. The
participants were students who studied in health science
may have had a greater overall interest in and awareness
of the relationship between food intake and health.62
However, the large sample size and the consistency with
the observations from the current study and those available within the literature provide confidence in the outcomes from this study. It is also important to note that
while increased liking of food was associated with increase in consumption of foods within the food groups,
the magnitude was small and large numbers of participants are needed to find the effects.
Conclusions
Our findings demonstrate that food liking influences diet
quality and BMI in Australian young adults. As the liking
of food can be taught by repeated exposure especially
during childhood, it is important to continue to explore
strategies that increase the exposure and consumption of
foods associated with health, and reduce exposure to
foods associated with increased BMI and poorer dietary
quality. Strategies should also be explored to help those
participants who are considered overweight or obese, in
changing their flavour preference from unhealthy food
groups to healthy food groups.
