Understanding meal patterns: developing the evidence-base for nutrition messages. Little is known about the format, structure or context of meal patterns despite their importance for health. This project will examine the predictors of meal patterns of Australians. This will provide new information which will facilitate the design of more effective ways to communicate with consumers about healthy eating.
How eating patterns interact with activity, sleep and mood. This project aims to understand temporal eating patterns (the timing and distribution of food intake and eating occasions across the day) among adults and how these eating patterns interact with activity and sleep patterns. Eating, activity and sleep patterns form a lifestyle triad which may be important for well-being and productivity. The project will study eating, activity and sleep patterns in daily life, to examine their social dri ....How eating patterns interact with activity, sleep and mood. This project aims to understand temporal eating patterns (the timing and distribution of food intake and eating occasions across the day) among adults and how these eating patterns interact with activity and sleep patterns. Eating, activity and sleep patterns form a lifestyle triad which may be important for well-being and productivity. The project will study eating, activity and sleep patterns in daily life, to examine their social drivers, interactions and effect on mood. This project could enable these behaviours to be targeted, with the potential to promote healthy lifestyles and improve health, quality of life and productivity.Read moreRead less

Accuracy and cost-effectiveness of technology-assisted dietary assessment. This project aims to compare leading methods for technology-assisted dietary assessment. Excessive cost and questionable accuracy limit the routine use of dietary assessment and undermine decision making in Australia. This project intends to compare three technology methods of assessing diet with the current standard recall method used in population surveys in order to confirm if the use of food images and automated metho ....Accuracy and cost-effectiveness of technology-assisted dietary assessment. This project aims to compare leading methods for technology-assisted dietary assessment. Excessive cost and questionable accuracy limit the routine use of dietary assessment and undermine decision making in Australia. This project intends to compare three technology methods of assessing diet with the current standard recall method used in population surveys in order to confirm if the use of food images and automated methods provide new approaches to improve accuracy and consumer acceptability. Expected outcomes of this project include more accurate and acceptable methods of assessing dietary intake. These findings will inform decision making for researchers, policy makers and practitioners in Australia, and potentially lead to more regular population surveillance.Read moreRead less

Dietary sugarcane-derived polyphenols reduce obesity. The Australian Sugar Industry is a billion dollar industry with refined sugar being calorie-rich but nutrition poor. Consumption of refined sugar is a main contributor to the increasing problem of obesity and metabolic syndrome, costing the Australian health system billions of dollars annually. The principal outcomes of this project will be to show that the polyphenols contained in the waste products from sugar refining can be used to reduce ....Dietary sugarcane-derived polyphenols reduce obesity. The Australian Sugar Industry is a billion dollar industry with refined sugar being calorie-rich but nutrition poor. Consumption of refined sugar is a main contributor to the increasing problem of obesity and metabolic syndrome, costing the Australian health system billions of dollars annually. The principal outcomes of this project will be to show that the polyphenols contained in the waste products from sugar refining can be used to reduce body fat and insulin resistance. These outcomes have enormous implications for human health and disease, and for the sugar industry, thus providing a competitive edge in the world sugar market.Read moreRead less
Development and evaulation of novel foods enriched with very long chain omega-3 fatty acids. This project is a collaborative effort between Meadow Lea Foods, Clover Corporation, and the Universities of Wollongong and Western Australia. The aims are 1) to develop a range of functional foods enriched with omega-3 from tuna oil; 2) to see whether the recommended omega-3 intake, currently nor met by most Australians, can be achieved by including these foods in the diet; 3) to evaluate sensory and he ....Development and evaulation of novel foods enriched with very long chain omega-3 fatty acids. This project is a collaborative effort between Meadow Lea Foods, Clover Corporation, and the Universities of Wollongong and Western Australia. The aims are 1) to develop a range of functional foods enriched with omega-3 from tuna oil; 2) to see whether the recommended omega-3 intake, currently nor met by most Australians, can be achieved by including these foods in the diet; 3) to evaluate sensory and health attributes and other factors that may impact on consumer acceptability hence market potential of the food range. There is little evidence of the feasibility let alone health and social benefits of utilising novel foods to meet the dietary omega-3 recommendation. We expect a) to show how consumers could benefit by using a range of such foods in their customary diet; b) to critically set this achievement within the context of current social trends in food product development.

Summary
Fish and fish oils contain fats known as omega-3 fats. These have health benefits in adult conditions such as rheumatoid arthritis and heart disease, and they are necessary for proper brain and eye development in infants. However, much of the population does not like to eat fish and also, world fish stocks are under stress. Thus, a sustainable alternative source of omega-3 fats needs to be explored. Some vegetable oils such as canola, echium, and flaxseed oils have omega-3 fats. However, these a ....Fish and fish oils contain fats known as omega-3 fats. These have health benefits in adult conditions such as rheumatoid arthritis and heart disease, and they are necessary for proper brain and eye development in infants. However, much of the population does not like to eat fish and also, world fish stocks are under stress. Thus, a sustainable alternative source of omega-3 fats needs to be explored. Some vegetable oils such as canola, echium, and flaxseed oils have omega-3 fats. However, these are not the same as the omega-3s in fish oil. In general, vegetable omega-3s are known as short-chain omega-3s whereas those in fish are long-chain. When the vegetable oil omega-3s are consumed in the diet, the body must convert them to the fish-type, or long-chain, omega-3s in order to gain the health benefits. Currently, human metabolism is poor at doing this conversion. Our studies suggest that the amounts and blends of fats in most diets are well below optimal for conversion to long-chain omega-3s in the body. In particular, our studies show that there may be no point in simply adding more vegetable omega-3 fats to the diet. This project will examine the enzymes that convert the short-chain to the long-chain omega-3 fats. In particular, it will examine how the dietary fats interact with each other in detrimental ways to suppress activity of the conversion enzymes necessary for long-chain omega-3 formation. Evidence for the health benefits of fish-based omega-3 fats is very strong and it is an approach to health that most people can undertake on their own. Our lack of knowledge of the best way to use plant-based omega-3 fats is a large impediment for a more sustainable and broader based use of omega-3 fats. The results from this study will begin to fill in this knowledge gap. The results will be useful across a range of activities that are determinants of the kinds of fat that we eat. These include oil seed breeding, food manufacture, and dietetics.Read moreRead less
