Abstract
Background: Current dietetic practice in Australia aimed at reducing risk of Type 2 Diabetes Mellitus (T2DM) provides dietary advice to Asian populations which often involves meal suggestions that are culturally inappropriate thus decreasing compliance with dietary advice. The aim of this project was to modify traditional high GI Asian breakfast meals to lower GI versions and to develop culturally acceptable meal options that could help with glycaemic control in South East (SE) Asian and Chinese populations. The cultural appropriateness of the modified test meals was also determined.
Methods: Twenty participants were recruited and placed into either the SE Asian group (n = 12) or the Chinese group (n = 8) based on their self-identified ethnic background. Participants were assigned to the modified traditional breakfast meal (either SE Asian or Chinese) or porridge oats in a randomised crossover design. Each meal was matched for macronutrient composition and provided 50g of available carbohydrate. Measurements of blood glucose, appetite and satiety and cultural appropriateness of the meals were taken over a 3 h postprandial period.
Results: There were no significant differences (P > 0.05) in glycaemic response between the modified SE Asian breakfast meal and the porridge oats (173 ± 61 vs 152 ± 61 mmol.min/L, respectively) or between the modified Chinese meal and the porridge oats (163 ± 74 vs 144 ± 67 mmol.min/L, respectively) using repeated measures ANOVA. Qualitative analysis found that preparation time was a key determinant of breakfast choice in both groups.
Conclusion: These results indicate that small modifications to traditional meals may be a viable alternative option in diabetes prevention.

Introduction
The food choices people make determine their food intake and influence their nutritional status. Food choice is made based on a range of determinants including sensory attributes, cultural habits, lifestyle factors and food trends [1]. While food habits are systematically interrelated with one’s traditional cultural behaviour [2], it is also recognised that food habits continually change as people travel, migrate and are exposed to a different environment [3].
Australia contains a large (and growing) Asian population, which is grouped into certain ethnic groups including South East (SE) Asians, North East Asians and Southern and Central Asians [4]. According to Australian Institute of Health and Welfare (AIHW) 35% of people with Type 2 Diabetes Mellitus (T2DM) in 2001 were born overseas, more common among Asians [5]. The introduction of Western culture into Asian lifestyle seems to make them more susceptible to T2DM [6]. The regular consumption of high Glycaemic Index (GI) and/or Glycaemic Load (GL) meal options such as white rice and/or white flour as their main carbohydrate source in Asian diets is thought to be a contributing factor [7-12]. Breakfast meals prepared with white rice and white flour is a common practice in the Asian region [13]. The regular consumption of high GI foods has been shown to increase the irregular fluctuation of blood glucose levels and hence is associated with T2DM and related metabolic diseases [14]. Excessive postprandial glucose excursions are a risk factor for developing T2DM. This may explain why Asians exhibit a 2-3-fold larger postprandial glycaemic response than Caucasians [15-17]. Low GI foods are known to improve glycaemic control in those with or at risk of developing T2DM and are recommended as a dietary strategy in dietetic practice [18-20]. Hence, it is critical for dietitians and other healthcare professionals to gain in-depth knowledge and skills in facilitating healthy and culturally appropriate food choice changes in this population [21]. Like other cultures, many Asians have difficulties in adapting to new diets after migrating to a Western environment such as Australia especially the older generation [22,23]. Thus Australian-trained healthcare professionals face the challenge of promoting food choice change aligned with both theoretical knowledge and cultural appropriateness, which are often conflicting with each other. Since low GI diets have been shown to be effective in managing blood glucose levels in T2DM, many diabetic Asian patients in Australia are currently advised to drastically switch their traditional savoury breakfast choices to Western options such as wholegrain bread or sweet oat porridge, ignoring the patients’ needs and cultural preferences. Despite knowledge that culturally tailored intervention has been shown to be more effective [24], medical nutrition prescriptions delivered by dietitians and healthcare professionals are largely based on studies conducted with Caucasians using Western foods, thus limiting applications to Asian counterparts. By incorporating selective low GI Asian food choices, traditional breakfasts can be modified to fit to practice and also accepted culturally. For example, the use of high GI rice, such as Jasmine (GI = 109, GL = 46) or medium grain (GI = 89, GL = 36) can be substituted with low GI rice varieties, such as long grain (GI = 50, GL = 21) or Basmati (GI = 58, GL = 22), or added with legumes without changing the sensory characteristics and at the same time culturally acceptable.
Thus, this unique study sought to carefully select the most commonly consumed breakfast meals by Asians from two different regions (Chinese and SE Asians) and to modify the traditional breakfasts to lower GI versions. The glycaemic response of the modified breakfasts was compared to the recommended (Western) oat breakfast cereal. The perceived satiety, acceptance and cultural appropriateness of the modified breakfast meals were also assessed along with biochemical and physical analysis. We hypothesised that the modified versions of the traditional breakfast meals will have a comparable glycaemic response to the oat breakfast meal and will be culturally appropriate and accepted by the relevant healthy Asian population.
Materials and Methods
Study design
This study employed a mixed methods research approach, with an arm of a randomised, non-blind control trial and an arm of qualitative assessment for exploring cultural appropriateness of the meals. The study was conducted in the Department of Nutrition, Dietetics and Food, at Be Active, Sleep and Eat (BASE) Facility, Monash University, Melbourne, Victoria, Australia. This study was approved by the Monash University Human Research Ethics Committee (Project Code: CF14/1227-2014000551).
Recruitment
Participants were recruited between May to August 2014 via flyers placed around Monash University campuses (Notting Hill, Clayton, Caulfield and Monash Medical Centre) and local libraries in the City of Monash, online advertisement on the local media of Monash University and group email to all the staff and students of Monash University and to professional networks.
Inclusion criteria
The inclusion criteria were as follows: age 18-65 years, stable body weight in the last 6 months, BMI between 18.5-26.9 kg/m2 (criteria set for Asian population), fasting blood glucose value <6.1 mmol/L, unrestrained eating pattern, non-smokers, no drug or excessive alcohol consumption, normotensive, without chronic diseases and not pregnant or lactating.
Screening
To determine their eligibility, interested individuals were asked to complete health and habitual physical activity questionnaires. Screening appointments were made to potentially eligible participants identified by the questionnaires. Screening appointments involved anthropometric, blood pressure and fasting blood glucose measurements, carried out using standardised methods in the fasting state. Height was measured using a stadiometer (Harpenden stadiometer, Holtain, Crymych, UK). Body weight was recorded using Seca scales (Seca 874, Hamburg, Germany). BMI was calculated with the standard formula weight (kg)/height2 (m2). Body composition was calculated using Bioelectrical Impedance Analysis (BIA) analyser (QuadScan 400, Bodystat, Douglas, Isle of Man). Blood pressure was measured with an automatic device (Conex ProBP 3400, Welch Allyn, NY, USA). Fasting blood glucose was recorded by obtaining capillary blood using a single-use lancing device (HaB Direct Oceania, Queensland, Australia) and analysed using an Accu-Chek blood glucose analyser (Accu-Chek Performa, Roche Diagnostics, Mannheim, Germany). All measurements were performed with the participants wearing light clothing without shoes. Subjects were given full details of the study protocol and the opportunity to ask questions. All subjects gave written consent prior to participation.
Test meals
The test meals were oat porridge (rolled oats prepared with low fat (1.3%) lactose-free milk, (Zymil, Pauls, South Brisbane, Australia) served with honey and almonds), congee (savoury rice porridge containing sweet potato and oats served with peanuts and tofu) and nasi lemak (coconut rice served with chilli sambal, cucumber, peanuts and egg). The two Asian test meals were chosen as commonly eaten breakfast meals in the Chinese and SE Asian populations, respectively [13], compared with a reference meal (oat porridge) used in Western breakfast. The serving size and nutrient values of each meal are given in table 1. The type of rice (as the main source of carbohydrate) in the Asian test meals were modified from traditional recipes to having ingredients with low GI that are assumed culturally appropriate. Mahatma long grain rice (Riviana Foods, Wetherill Park, NSW, Australia) (GI = 50), Mahatma Basmati rice (Riviana Foods, Wetherill Park, NSW, Australia) (GI = 58) and Uncle Toby’s rolled oats (Nestlé Australia Ltd, Sydney, Australia) (GI = 42) were used in the congee, nasi lemak and oat porridge recipes, respectively, instead of their high GI counterparts. The GI of these grains were tested in previous studies [25]. The ingredients added in the modified recipes are provided in the appendix 1. All meals were analysed using Foodworks analysis (2009; Xyris Software, Queensland, Australia) to ensure they equally contained 50 g available carbohydrates. Energy, macronutrient and fibre contents across the three meals were also matched. All meals were prepared fresh by one researcher in the commercial kitchen of the department, on the mornings of the test and served warm.

Study protocol
The participants were divided into the Chinese and SE Asian groups, according to their self-identified ethnic background. Participants in the Chinese group were assigned the congee as their modified Asian breakfast while those in the SE Asian group were given the nasi lemak. Both groups were given oats porridge as the Western breakfast (reference food). The two meals were provided randomly on two separate mornings, with a washout period of at least two days. Randomisation was performed by flipping an Australian twenty-cent coin. The participants were advised to follow their habitual diet and exercise routine throughout the study period.
Glycaemic response testing
The protocol used to measure glycaemic response was adapted from that described by Wolever et al., [26] and Brouns et al., [27]. The meals were tested in the morning, after a 12 h overnight fast. Prior to the test, the participants were asked to complete a short questionnaire regarding the time and amount of their last meal, consumption of alcohol and caffeine, exercise and level of stress. Fasting blood glucose samples were taken at -5 min and 0 min before consumption of the test meal and the baseline fasting blood glucose level was taken as the mean of these two values. Immediately after the second fasting blood sample was taken at 0 min, the participants were required to consume the test meal at a comfortable pace within 15 min. Further blood samples were obtained at 15, 30, 45, 60, 90 and 120 min after the participants started eating the test meal. The test foods were served with 200 mL water, further 200 mL water was given during the subsequent 120 min. Subjects were asked to maintain minimal physical activity throughout the tests. Blood was obtained by finger-prick as described above.
Calculation of the glycaemic response
For each test food, the Incremental Area Under the Curve (IAUC), ignoring the area beneath the baseline, was calculated geometrically [28]. The glycaemic response for each test meal was expressed as the mean IAUC for the whole group.
Satiety
One-hundred-millimetre continuous line Visual Analogue Scales (VAS) were utilised to measure subjective feelings of hunger, fullness, desire-to-eat and prospective food consumption. The volunteers provided VAS data at baseline (0 min) and at 30, 60, 90, 120, 150, and 180 min after the commencement of eating the test food. The specific questions asked were, ‘How hungry do you feel?’, ‘How full do you feel?’, ‘How strong is your desire to eat?’ and, ‘How much food do you think you can eat?’
Cultural appropriateness questionnaire
A 5-item cultural appropriateness questionnaire was designed specifically for the study, to determine participants’ usual breakfast choices and the cultural acceptability of the breakfast meals provided. At 60 min after consuming the provided meal, the participants completed a cultural appropriateness questionnaire, as described in the appendix 2. The questionnaire collected information on existing breakfast habits and exploring determinants of breakfast choices.
Food diary
After the completion of each test, the participants were asked to complete a 24 h food diary, indicating their consumption of all the foods and drinks consumed after the blood glucose measurement. They were reminded to follow their usual eating and exercise patterns during the study period.
Statistical analysis
Statistical analysis was performed using Statistical Package for the Social Sciences (version 17.0; SPSS, Chicago, IL, USA) and data and figures were processed in Microsoft Excel 2011 spread sheet (2006, Reading, UK). The IAUC was determined for GR and satiety using the trapezoidal rule for values above the baseline. The relative increment in the GR at any time point compared with the baseline value was used to assess the differences at each time. The differences were assessed using a three-factor Repeated-Measures Analysis of Variance (RM-ANOVA) with differences between the meal assessed using contrasts within the ANOVA. Significance was set at P < 0.05. Values are presented as means ± Standard Errors of the Mean (SEM) unless otherwise stated.
Results
A total of 20 subjects (7 male, 13 female) with a mean age of 25 years (± 8) participated in the present study. All participants (mean ± SD) were within the normal BMI range (22.2 kg/m2 ± 2.2), body fat percentage (22.0% ± 6.7) and fasting blood glucose (4.9 mmol/L ± 0.4).
Twelve participants (3 male, 9 female) were self-identified as SE Asians and 8 participants (4 male, 4 female) as Chinese. Table 2 indicates the anthropometric criteria for Chinese and SE Asian groups, with no difference in any of the criteria between groups (P > 0.05).

Glycaemic Response and Satiety
The glycaemic response by Chinese and SE Asian groups to the different meals is shown separately in figures 1, 2 and combined in figure 3. The mean (± SEM) blood glucose response for the reference food (oats) was 169 ± 15 mmol.min/L for all participants with no significant difference in response between the SE Asian group (173 ± 18 mmol.min/L) and the Chinese group (163 ± 30 mmol.min/L) (P > 0.05).

Mean fasting blood glucose levels and incremental area under the curve data are shown in table 3. There were no statistically significant differences in the glycaemic response between the traditional SE Asian breakfast meal (nasi lemak) and the oat porridge (P = 0.37) or between the traditional Chinese breakfast meal (congee) and the oat porridge (P = 0.46). Furthermore, the peak change in blood glucose and the time taken to achieve peak blood glucose did not significantly differ between the oat porridge and the traditional test meals. There were also no significant differences (P > 0.05) in perceived ratings of hunger, appetite and satiety or in actual food intake between the groups or between different meal conditions.

Reported length of stay in Australia
All participants (n = 20) completed the 5-item questionnaire. The responses were collated and summarised in table 4. Three from each group (SE Asian and Chinese) were born in Australia. The other participants reported to have an average stay (± SD) in Australia of 6.4 years (± 9.1) for the SE Asian group and 18.2 years (± 5.8) for the Chinese group.

Breakfast habits
Every participant reported habitual consumption of breakfast. The most common breakfast choices were cereals, bread with a spread and muesli with yoghurt. Some participants reported having an Asian breakfast irregularly, however, only if it was left over from dinner the night before.
Determinants of breakfast choices
The determinants of breakfast choices were preparation time required, taste preference, nutrition, familiarity and accessibility. Preparation time was the strongest determinant of breakfast choice. Many participants reported ‘liking’ the modified Asian breakfast but stated that they would not have it regularly as ‘it requires a long preparation time’. It was also highlighted that many would like eating oats regularly due to its perceived health benefits.
Although all participants from SE Asian group liked the modified version of nasi lemak that was prepared for them, many claimed that they will have this meal due to its perceived health benefits. However, long preparation time hindered some participants from having this meal for breakfast. It was also reported that some participants have moved away from having Asian breakfast, possibly secondary to dietary acculturation, or having least experience growing up eating Asian breakfast in Western culture when busy parents prefer to spend less time preparing hot breakfast for their children.
While in Chinese group, the prepared congee was liked much by all participant but some reported that they would not consume the modified congee regularly for its long preparation time. Again, due to this factor, and as younger generation, they have adapted to consume Western breakfast more regularly.
Discussion
This is the first study known to the authors to examine the effect of modified traditional Chinese and SE Asian breakfast meals on glycaemic response compared with oat breakfast cereal. Oat-enriched diet has been generally recommended to and consumed by T2DM patients to improve insulin resistance and reduce inflammation [29,30]. Recent studies demonstrated the effect of protein- or amino acid-rich mixed meals in reducing GI and the GR to South Asian staples [31,32]. Our study has illustrated that making small modifications to traditional breakfast meals can generate a similar GR to the currently recommended oat breakfast cereal in these populations. Previous research has shown that GI values of foods commonly tested on Caucasian subjects are likely to be applicable to Asian populations living in their own countries with no change in the GR [15,33]. The present study has highlighted that the GR to oat breakfast cereal was similar in Chinese and SE Asian subjects. Furthermore, the GR of each modified traditional breakfast was also similar to the consumed Western breakfast. These results create an opportunity in dietetic practice to offer the option of modifying traditional meals using low GI and GL ingredients rather than opting for drastic dietary change, depending on patients’ individual preference.
Many studies on GR to foods focus purely on the blood glucose data. The modified Asian breakfasts were shown to have a lower GR, similar to the Western oat porridge, and this could inform clinical practice recommendations towards recipe modification of traditional meals. However, an additional important aim of this study was to examine the cultural appropriateness of modified traditional breakfast meals. Interestingly, despite the promising physiological results and participants claiming preference to the modified breakfast meals, many also reported that they would not have the traditional breakfast regularly due to time constrain. In fact, as the reported usual breakfast choices reflected, cultural appropriateness was not the primary breakfast choice determinant. Similarly, previous anthropologic study in the United States has reported that Chinese immigrants chose to eat Western-style breakfasts as preparation of traditional breakfast was ‘too time-consuming’ [34].
The duration of stay in Australia may be one of the factors whether or not participants are able to acclimatise to Western lifestyle including breakfast eating habits. Five Chinese participants that were not born in Australia have lived in the country on average of 18 years, while 9 migrated SE Asian participants have only lived in Australia on average of 6.4 years. Our results indicate that the longer they have lived in the country, the more exposed and adaptable they are to the Western food. The length of stay in the western environment also somehow influences Asians’ dietary intakes, where GI (and GL) inversely associated with length of residence [35]. Younger Asian generations have been shown to be more likely to adopt Western foods at certain meals, while older generations preferred to consume western foods with traditional diets [36]. However, younger Asian generation would still prefer to have traditional meals containing rice for dinner [37]. Since most participants were from younger generation of Asians further analysis using older adults would warrant a better outcome.
Other possible explanation is that eating out for breakfast is also very common in Asia and hot breakfasts such as savoury rice porridge and nasi lemak tend to be readily available cheaply on the street [13], allowing time-pressured Asians to enjoy their traditional culturally appropriate breakfast without the hassle of preparation. The GI of nasi lemak varied between medium (GI = 66) in one study [38], too high in another (GI = 99) [39], which depends on many factors especially the rice varieties used. Hence, we decided to utilise low GI Basmati rice variety (GI = 58) to reduce the overall GR of the prepared meal. Results indicate that by opting to use low GI rice variety, that is culturally accepted by participants, without dramatic changes in the sensory qualities, GR of nasi lemak is similar to oats porridge. Comparable results were also obtained for Chinese group, where culturally accepted low GI long grain rice (GI = 50) was used to lower overall GR of modified congee. Traditionally, broken rice with increased starch gelatinisation, is commonly used to make congee, which has a high potential GI depending on cooking time and test subjects (79 - 107, average 86) [33,40]. This study reported that when living in a Western society where traditional hot breakfasts are not as accessible, Asians adapted to eat quick and convenient Western breakfasts such as cereals, bread with a spread and muesli with yoghurt. Since half of the participants would still prefer to have their traditional breakfast with healthier versions, this idea may present an opportunity for the food industry to investigate the acceptance and develop novel ‘ready-to-eat’ traditional meal varieties.
The present study has also highlighted that perceived health benefits was another important cultural-specific determinant of food choice. As food is culturally valued as ‘a natural healing agent or a form of medicine’ among Asians [41], many participants in this study reported that they would willingly adopt the modified Asian breakfasts for better health. Previous research reported that Chinese living in Taiwan and Malaysia demonstrated a clear difference from their New Zealand and Japanese counterparts, for having health as one of the strongest food choice motives, rated it higher than sensory appeal and familiarity [42]. This helps to in part explain the Asian participants choosing to eat breakfast cereals and muesli marketed on their health benefits, even though they were culturally-unfamiliar breakfast food choices.
A considerable strength of the current study is that the need for this research was driven by requests from T2DM patients being seen in clinical practice. Furthermore, the two Asian populations under investigation are representative of having the highest incident of T2DM in the world [43]. The use of a mixed methods approach (qualitative and quantitative) has enabled us to explore the actual determinants of breakfast choice in these ethnic groups.
We do, however, acknowledge that the relatively narrow age range of participants and small sample size suggest the need for further research in these populations. Since younger adults were used as participants in this study, who are generally more adaptable to Western culture (including their breakfast choices), a more definite outcome was not perceived. Older adults were not used in this study either due to the eligibility criteria or not physically available to volunteer for the study. Despite their age and health status, this study also aimed to determine the cultural appropriateness of the modified traditional breakfasts.
In this study, a random selection of congee for Chinese and nasi lemak for SE Asians were chosen as most commonly consumed breakfast. Others have mentioned that Asians also tend to choose breakfast containing bread, pastry or noodles that are known to have high GI [13,44], which also require further investigation for their GR. Although it could have strengthened the outcome of this study, the actual GI value of the congee, nasi lemak and oats cereal were not tested before or after being modified to reduce the frequency of participants’ test visits, hence to reduce withdrawal. The present study also did not capture dietary acculturation due to significant differences in length of stay among the participants, which is possible in bigger sample size.
In conclusion, these results indicate that small modifications to traditional meals may be a viable alternative option in diabetes prevention. This study further highlights the importance of acknowledging key determinants of food choice in dietary strategies for different population groups. This information suggests that rather than spending resources exploring different breakfast meal options, time should instead be spent understanding these populations, their dietary habits, low GI and GL ingredients and developing necessary skills to help facilitate dietary change to decrease T2DM risk. The information generated from this study will be used to inform dietetic practice in the Australian Asian community.
