This study with Australian consumers investigated how appealing different health claims combined with particular food carriers were to Australian consumers, and compared the results of a similar study with Dutch consumers. 149 shoppers considered up to 30 different food concepts, rating how ‘attractive’, ‘believable’, and ‘new and different’ they found each concept and their ‘intention to try’. Each variable was significantly related to intention to try (p<0.001) and together explained 56% of the intention score. Claims and carriers independently had a significant effect on ratings of attractiveness and intention to try but, unlike the Dutch study, the carrier was a more important predictor of intention to purchase than the claim. Implications for regulation of health claims for food are discussed.

Changes of molecular dynamics in the α-to-β transition associated with amyloid fibril formation were explored on apo-myoglobin (ApoMb) as a model system. Circular dichroism, neutron and X-ray scattering experiments were performed as a function of temperature on the protein, at different solvent conditions. A significant change in molecular dynamics was observed at the α-to-β transition at about 55 ˚C, indicating a more resilient high temperature β structure phase. A similar effect at approximately the same temperature was observed in holo-myoglobin, associated with partial unfolding and protein aggregation. A study in a wide temperature range between 20 K and 360 K …

This study evaluated the menus and food service experience of inmates in three correctional centres in Sydney (one minimum security, one high security, and one for women). Menus were evaluated against recommended dietary intakes, dietary guidelines and nutrition policy statements. Menus generally provided a well varied selection of foods which met the majority of individual nutritional requirements and dietary guidelines - assuming all food provided was consumed. Focus groups and interviews with 35 inmates explored their attitudes about and experiences of the foodservice provision. Sixteen key themes of concern were identified, including: • Complaints about food quality, lack of choice, …
Cereal Grains, Legumes, And Weight Management: A Comprehensive Review Of The Scientific Evidence, P. G. Williams, S. J. Grafenauer, J. E. O'Shea
Cereal Grains, Legumes, And Weight Management: A Comprehensive Review Of The Scientific Evidence, P. G. Williams, S. J. Grafenauer, J. E. O'Shea
Faculty of Health and Behavioural Sciences - Papers (Archive)
There is strong evidence that a diet high in wholegrains is associated with lower BMI, waist circumference and risk of being overweight; that a diet high in wholegrains and legumes can help reduce weight gain; and that significant weight loss is achievable with energy controlled diets that are high in cereals and legumes. There is weak evidence that high intakes of refined grains may cause small increases in waist circumference in women. There is no evidence that low carbohydrate diets that restrict cereal intakes offer long term advantages for sustained weight loss. There is insufficient evidence to make clear conclusions …

Participants were divided into groups to discuss five topics: priority areas to include in a critical literature review, best formats for presentation of guidelines, particular local issues to consider, information to be included in appendices, and methods to encourage the adoption and use of …
High Plantar Pressures And Foot Pain: Are They Contributing To Falls In Older Adults?, Karen J. Mickle, Bridget J. Munro, S. R. Lord, Hylton B. Menz, Julie R. Steele
High Plantar Pressures And Foot Pain: Are They Contributing To Falls In Older Adults?, Karen J. Mickle, Bridget J. Munro, S. R. Lord, Hylton B. Menz, Julie R. Steele
Faculty of Health and Behavioural Sciences - Papers (Archive)
Falls, the leading cause of injuries in older adults, typically occur during ambulation. As such, gait and balance abnormalities are frequently cited as falls risk factors. During normal gait, the foot is the only source of direct contact with the ground and, therefore, it plays a substantial role in maintaining stability and balance. Foot pain has been found to impair balance and gait in women (Leveille, 1998), and has been shown to be falls risk factor in institutionalised elders (Menz, 2006), however it unknown whether foot pain is a risk factor for falling in community-dwelling older adults. As foot pain …

Breast cancer is a prevalent, life-impacting disease. With increasing incidence rates and a growing number of survivors, greater efforts must be directed towards improving the physical functioning and quality of life (QoL) of women living with a diagnosis of breast cancer. Although exercise interventions have been reported to provide these benefits, without the development of adverse events. many impediments to exercise exist (Rogers, 2007). While several psychosocial or physical capacity impediments to exercise have been investigated, a recent study found that a substantial proportion (70.3%) of women living with a breast cancer diagnosis reported experiencing bra discomfort during exercise (Gho, …

Ischaemic preconditioning is a powerful cardioprotective phenomenon. Cardioprotection afforded by (n-3) polyunsaturated fatty acids (PUFA) also suggests preconditioning-like effects. This study examined the effects of dietary fish oil on heart function and injury during myocardial ischemia and reperfusion and interactions between diet and ischemic preconditioning (IP). Male Wistar rats were fed diets containing 10% fat by weight including either 7% fish oil + 3% olive oil (n-3) PUFA); 5% sunflower seed oil + 5% olive oil ((n-6) PUFA); or 7% saturated fat-rich beef tallow + 3% olive oil (SF) for 6 weeks. Isolated perfused hearts subjected to 30min regional ischemia …

The Effects Of Antipsychotics On The Density Of Cannabinoid Receptors In The Dorsal Vagal Complex Of Rats: Implications For Olanzapine-Induced Weight Gain, Katrina Weston-Green, Xu-Feng Huang, Mei Han, Chao Deng
Faculty of Health and Behavioural Sciences - Papers (Archive)
Some atypical antipsychotics clinically used to treat schizophrenia induce weight gain by unknown mechanisms. The dorsal vagal complex (DVC) of the brainstem and the endogenous cannabinoid system are implicated in the regulation of appetite signalling and food intake. We investigated whether antipsychotic drugs alter cannabinoid receptor-binding density in the DVC. Female Sprague–Dawley rats were treated with olanzapine, haloperidol, aripiprazole or vehicle for 1 wk (short-term) or 12 wk (chronic). Quantitative autoradiographic methods were employed to investigate the binding density of cannabinoid receptors in the DVC using a highly sensitive Beta Imager. Short-term olanzapine induced a significant 39% decrease in cannabinoid …

Malnutrition is prevalent in elderly hospitalised patients and has been associated with longer lengths of stay (LOS), higher rates of complications and increased hospital costs. Feeding assistance has traditionally been the role of nurses, however with an ageing population and an ever-increasing workload there may not be sufficient time to ensure the nutritional care of all patients. A program in which trained volunteers assist, socialise and feed nutritionally vulnerable patients at lunch on weekdays has been initiated in a major suburban hospital in Sydney. The pilot study reported here aimed to evaluate the lunchtime assistance program in terms of dietary …

The Importance Of Omega-3 Fatty Acids In Children's Diets, Barbara J. Meyer
Faculty of Health and Behavioural Sciences - Papers (Archive)
The 3 main types of fat in our diet are saturated fat, monounsaturated fat and polyunsaturated fat. Saturated fatty acids do not contain any carbon double bonds, as the fatty acid is fully saturated with hydrogens. Monounsaturated fatty acids, as the name suggests contain fatty acids with one carbon double bond (i.e. mono meaning one) and likewise polyunsaturated fatty acids contain two or more carbon double bonds.

Using a context-based case-control trial, 41 adults with type 2 diabetes mellitus were randomized into four groups to complete dietary assessments (computerized or interviewer administered) at 0, 2 and 8 weeks and food records at 0 and 2 weeks. Repeatability of reported energy, total fat, saturated, polyunsaturated and monounsaturated fatty acids between the computerized and interviewer administered methods were assessed using repeated measures ANOVA. Paired t-tests and Pearson's correlations determined relative validity of the assessments.

Faculty of Health and Behavioural Sciences - Papers (Archive)
The domain of life planning and personal development includes the important techniques of values clarification, strengths identification, goal setting and action planning. In the past two decades practices such as life coaching have grown in popularity (Green, Oades & Grant, 2006). Moreover, in mental health contexts, the recovery movement has challenged the illness and deficit focus (Andresen, Caputi, Oades, 2006; Oades et al, 2005) whilst within the discipline of psychology, the positive psychology movement has questioned the negative focus of clinical psychology (Resnick & Rosenheck, 2006). It is however easier to critique an existing area than the provide suggestions and …

To construct a nutrient database for use with a large population-based cohort study, the Blue Mountains Eye Study, dietary intakes were estimated using the Australian electronic food composition nutrient databases to which values for additional nutrients were added, including folate, vitamin B12, carotenoids and fatty acids. The addition of nutrient data from alternative, overseas, database sources may be useful in relation to the assessment of outcome measures, however the data obtained from these sources need to be interpreted with care, especially in relation to absolute quantities of intake.

Dietary Fatty Acids And Age-Related Macular Degeneration, Victoria M. Flood, Paul Mitchell
Faculty of Health and Behavioural Sciences - Papers (Archive)
Age-related macular degeneration (AMD) is a leading cause of vision loss and blindness among older people. It is important to identify modifiable risk factors which could prevent or slow the progression of this chronic disease. Dietary fatty acid intakes have been investigated in epidemiological studies as it is plausible that individual lipids have properties which modulate cellular damage in the eye. This paper reviews epidemiological studies investigating links between fatty acids and AMD. Mixed evidence has related the sub-types of saturated and monounsaturated fatty acids to AMD, but nearly all epidemiological studies have demonstrated some level of AMD protection from …

Consumers are interested in making healthier food choices but the mandatory nutrition information panel currently in use in Australia is not easily understood or interpreted by most consumers. A simple nutrition signpost would be valuable. This paper reviews two nutrition signposting systems currently being considered for adoption in Australia. The authors conclude that a system similar to the colour-coded Traffic Light System is likely to be most useful.
Schizotypy And Psychosis-Like Experiences From Recreational Cannabis In A Non-Clinical Sample, Emma Barkus, Shon Lewis
Schizotypy And Psychosis-Like Experiences From Recreational Cannabis In A Non-Clinical Sample, Emma Barkus, Shon Lewis
Faculty of Health and Behavioural Sciences - Papers (Archive)
Background. The relationship between cannabis use and psychosis is still a matter for debate. Accounting for the individual differences in subjective experiences to recreational cannabis use in the general population may hold some clues to the aetiological relationship between cannabis and psychotic symptoms. We hypothesized that schizotypy would account for the individual differences in subjective experiences after cannabis use but not in patterns of use. Method. In a sample of 532 young people who had used cannabis at least once, we examined the relationship between the Cannabis Experiences Questionnaire (CEQ) and the Schizotypal Personality Questionnaire (SPQ). Additionally, we examined the …

Personality And Cannabis Use, Emma Barkus
Personality And Cannabis Use, Emma Barkus
Faculty of Health and Behavioural Sciences - Papers (Archive)
Cannabis is one of the most widely used illegal substances in the world. Its use has been reported to be over-represented in many psychiatric conditions and has frequently been found to predate the onset of psychiatric symptoms. However, cannabis may also have detrimental effects on the general population. Factors that predict the onset of use are receiving increased attention to aid in identifying groups of young people who may be more prone to consume cannabis. Personality traits may be one such factor as they are readily identifiable and offer information that can be used for improved targeting of educational material …

Dynamic changes in human stability, such as those induced by upper body movements, are preceded by anticipatory postural adjustments (APAs) in the rest of the body. We measured the excitability of the stretch reflex of the triceps-surae muscle group during APAs associated with unilateral right arm raises in standing humans. Our results demonstrate that reflex excitability and underlying muscle activity are linked during the APA period, but that they differ in their relative timing. This supports the idea that reflexes are controlled independently of muscle activation.

Background: Cannabis use has been identified as a possible risk factor for developing schizophrenia. In a previous paper we reported preliminary evidence that cannabis use increases the likelihood of psychosis-like experiences in non-clinical respondents who scored highly on a measure of schizotypy. We now present findings from pooled data from 3 new follow-up studies comprising a sample of 477 respondents, of whom 332 reported using cannabis at least once. Sampling and Methods: As in our previous study, the psychological effects of cannabis were assessed with the Cannabis Experiences Questionnaire, from which 3 subscales can be derived; encompassing pleasurable experiences, psychosis-like …
