Summary
Over the last 20 years there has been a dramatic increase in allergic diseases in Australia as well as many other industrialised countries. This may be due to changes in our environment or diet. Over this period of time there has also been an increase in the dietary intake of n-6 fatty acids from vegetable oils and a corresponding decline in the intake of n-3 fatty acids from fish. Studies now indicate that there is a plausible link between these dietary changes and allergic diseases.

This may be due to changes in our environment or diet. Over this period of time there has also been an increase in the dietary intake of n-6 fatty acids from vegetable oils and a corresponding decline in the intake of n-3 fatty acids from fish. Studies now indicate that there is a plausible link between these dietary changes and allergic diseases. Furthermore, emerging data suggest that the potential benefits of increasing n-3 fatty acids may be greatest during pregnancy and before allergic responses are established. Our project aims to minimise allergies in children from families where at least one parent has an allergy. We will assess whether dietary n-3 fatty acid supplementation of pregnant women will result in fewer children with allergies at 1 and 3 years of age. If the proposed intervention is successful, it would be a safe, cheap, acceptable and effective strategy to prevent allergies in children at high risk.Read moreRead less
Many dietary recommendations are inconsistent and based on inadequate research based on 1970s technologies. As a result, the current recommendations are almost impossible to meet from foods, without nutritional supplements. Using state-of-the-art technology, this research aims to redefine the nutritional requirements omega-3 long chain polyunsaturated fatty acids, iron and iodine, as well as the correct balance of energy producing macronutrients in the diet of mothers and their children.
Alterations In Secretion And Gene Expression In Pancreatic Beta Cells Exposed To Lipid.

Summary
The project is aimed at a better understanding of the way in which fats control gene expression in the pancreatic beta cells of the islets of Langerhans. Because changes in gene expression are to likely to explain why exposure of these cells to fat disrupts their ability to release insulin, identification of these genes could explain why only some obese people develop Type 2 diabetes.
Effect Of High Dose Infant Fish Oil Supplementation And FADS 1 & 2 Genetic Polymorphisms On Cognitive Development And School Giftedness

Summary
This project will investigate the influence of fish oil supplementation during the first six months of life on intelligence, language, behaviour and school performance at age six. We will also investigate how genetic differences in fish oil metabolism can impact upon these relationships. The findings will enhance our knowledge pertaining to the potential benefits of fish oil on cognitive development, and will inform future practice regarding the high dose fortification of infant formula.
Does Maternal Supplementation With N-3 Long-chain PUFA In Pregnancy Influence Cognitive Development In Childhood?

Summary
During pregnancy, omega-3 fats (like those in fish) are deposited in the brain of the developing baby. Women get these fats from the diet but Australian women typically eat a diet low in fish. Because research has linked high fish intake in pregnancy with better IQ in children, omega-3 oils are included in some pregnancy supplements. However their effect on child development is not clear. This project will test whether taking fish oil while pregnant improves a child's IQ.
Improving Long-term Mortality Rates Following Sepsis.

Funding Amount

Summary
It is estimated that 37.9 million patients survive sepsis each year. Studies have demonstrated that among patients who survive for 30 days after admission for sepsis, over 40% die in the following two years. There are currently no guidelines that provide recommendations on post-hospital management of sepsis. This research programme aims to identify those patients at greatest risk of death and implement post-sepsis care with the aim to significantly reduce long-term mortality after sepsis.

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
