Smells that 'taste': Flavour perception and its consequences. The experience of flavour during eating and drinking has surprising social and economic ramifications. Our preference for sweet and fatty food has contributed to progressive increases in body mass over the last twenty years. Many experts now consider this to be a major public health crisis in the making. Economically, Australia is heavily dependent upon food exports, both in terms of primary production and value added processed food ....Smells that 'taste': Flavour perception and its consequences. The experience of flavour during eating and drinking has surprising social and economic ramifications. Our preference for sweet and fatty food has contributed to progressive increases in body mass over the last twenty years. Many experts now consider this to be a major public health crisis in the making. Economically, Australia is heavily dependent upon food exports, both in terms of primary production and value added processed food. Understanding the psychology of flavour, which is central to this project, should assist the development of non-fattening additives that appreciably alter fat and sweetness perception, creating new food products that are healthy, preferred and potential export earners.

Environmental impact on neuroendocrine and neurobiological mechanisms: treatment strategies and mimetics for maintaining good health. The current societal climate of industrialized countries such as Australia has shifted considerable over recent decades and is now one which is highly conducive to overfeeding and reduced physical activity. As a result, the incidence of obesity has risen markedly along with an associated increase in obesity-related chronic diseases such as cardiovascular disease, ....Environmental impact on neuroendocrine and neurobiological mechanisms: treatment strategies and mimetics for maintaining good health. The current societal climate of industrialized countries such as Australia has shifted considerable over recent decades and is now one which is highly conducive to overfeeding and reduced physical activity. As a result, the incidence of obesity has risen markedly along with an associated increase in obesity-related chronic diseases such as cardiovascular disease, stroke, obstructive pulmonary disease, type II diabetes, and many types of cancers. Less is known about the psychological and behavioural sequelae of this overfeeding. Calorie restriction mimetics may not only act as a preventative intervention to help reduce the incidence and severity of these major health problems, but also impact on social behaviour.Read moreRead less
Impacts of diet on the brain, body, and microbiome. Dietary habits determine cognitive function, metabolism and the composition of the gut microbiome. This project seeks to clarify the role of the gut microbiome in diet-induced changes to cognition. It aims to do so through longitudinal studies of cognitive function in which dietary patterns are systematically varied, and intervention studies where cognition is tested after experimentally manipulating the gut microbiome. Expected outcomes inclu ....Impacts of diet on the brain, body, and microbiome. Dietary habits determine cognitive function, metabolism and the composition of the gut microbiome. This project seeks to clarify the role of the gut microbiome in diet-induced changes to cognition. It aims to do so through longitudinal studies of cognitive function in which dietary patterns are systematically varied, and intervention studies where cognition is tested after experimentally manipulating the gut microbiome. Expected outcomes include new interdisciplinary knowledge spanning psychology, neuroscience, nutrition and metabolism. This project is timely given the enormous shifts in Australian dietary choices. The knowledge to be gained should provide benefits to individual and public health, agriculture, and food systems.Read moreRead less
Glucose facilitation of cognitive function: Effects of effort, age and glucose control. Age-related decline in mental capacity contributes to the economic (estimated at over 2 trillion AUD by 2050), social and human costs of an increasingly older Australian population. The studies in this program aim to understand the role of poor control of blood glucose in age-related cognitive deficits. The role of individual differences in biological (hormonal responses) and psychological (stress and appetit ....Glucose facilitation of cognitive function: Effects of effort, age and glucose control. Age-related decline in mental capacity contributes to the economic (estimated at over 2 trillion AUD by 2050), social and human costs of an increasingly older Australian population. The studies in this program aim to understand the role of poor control of blood glucose in age-related cognitive deficits. The role of individual differences in biological (hormonal responses) and psychological (stress and appetite) factors will also be assessed. A better understanding of the nature of age-related cognitive decline as it relates to biological processes such as blood glucose control will help to develop tangible strategies to combat age-related cognitive decline and dementia (which has been described as Type 3 diabetes).Read moreRead less
