Does Obesity Have The Characteristics Of Addiction?

Summary
The number of overweight or obese people in Australia has increased dramatically in recent years, increasing disease risk. The brain responds to palatable food in ways similar to the response to drugs of addiction, and this may explain why people find it hard to resist palatable food. Our work will explore whether obesity in rats has the characteristics of addiction by examining bingeing, craving, withdrawal and brain circuits in animals chronically exposed to palatable food.
Understanding The Immune Mechanisms Leading To Resolution Of Peanut Allergy

Funding Amount
$602,472.00
Summary
Food allergy affects up to 10% of children and rates are rising. The greatest rise has been in peanut allergy which is the commonest cause of life threatening reactions. Currently, there is no cure for food allergy. Management relies on food avoidance which is impossible to achieve. Recent deaths in children from food allergy highlight the need for an effective treatment. This project will examine what happens when you grow out of peanut allergy. New information will lead to possible cures.
A Multicentre Randomised Controlled Trial Of Probiotic And Peanut Oral Immunotherapy For The Treatment Of Peanut Allergy

Funding Amount
$2,887,302.00
Summary
A curative treatment for food allergy is required to prevent deaths and improve management. We recently trialed a new treatment for peanut allergy that was highly effective. Over 80% of children treated with Probiotic and Peanut Oral ImmunoTherapy (PPOIT) tolerated peanut as compared to 4% of children who received placebo. We now plan a larger multicentre trial to confirm these findings. If successful, we will have established a new treatment for peanut allergy and possibly all food allergies.
Interactions Between Protein Leverage, Variety, And Dietary Carbohydrate And Fat Content In The Control Of Energy Intake In Humans

Summary
Most attempts to understand human vulnerability to obesity have focussed on fat and carbohydrate, yet recent studies have shown a powerful role for protein: we eat more calories when dietary protein concentration is low. But how does protein interact with other aspects of the diet, notably the prodigious variety of foods available in modern environments and the balance of fat to carbohydrate? We will use controlled trials to investigate how these factors contribute to excess energy intake.
Probiotic Prawn Oral Immunotherapy (ProPIT) For Treatment Of Prawn Allergy

Funding Amount
$1,865,369.00
Summary
A ‘curative’ food allergy treatment is needed to prevent deaths and improve care. We recently showed that probiotic peanut oral immunotherapy (PPOIT) was highly effective for treating peanut allergy. 82% of PPOIT treated children gained tolerance compared to 4% of the placebo group. We will now test the combined probiotic-food OIT approach for treating prawn allergy. If successful, we will have identified the first treatment for prawn allergy and a platform treatment for other food allergies.
Dietary Intake Of Highly Processed Foods As A Contributor To Type 1 Diabetes

Funding Amount
$558,953.00
Summary
Modern food processing imparts desirable functional properties such as emulsification and longer shelf life. These biochemical modifications in our food may cause the body to turn on itself and destroy the cells which produce the sugar storage hormone insulin. This is important for survival and characterizes childhood onset diabetes and can also be seen in type 2 diabetes. This research will test some dietary and pharmaceutical interventions to slow the development of diabetes.
The Role Of Infant Food Allergy In The Natural History And Burden Of Allergic Disease Across The Early Years: The HealthNuts Study
Funder
National Health and Medical Research Council
Funding Amount
$1,722,373.00
Summary
The HealthNuts study of 4600 infants is the world’s first comprehensive population-based study of food allergy with objective measurement of true food allergy and will enable us to understand better the natural history of allergic disorders including food allergy, asthma, eczema and allergic rhinitis and the interplay of risk factors for development of these conditions in the first 6 years of life. The study will have important implications for clinical guidelines and public health policy.
A Randomised Controlled Trial To Prevent Eczema, Food Allergy And Sensitisation Using A Skin Barrier Improvement Strategy

Funding Amount
$878,163.00
Summary
In this world first study, we will test if building the infant skin barrier by using daily regular skin care treatment can reduce the incidence of eczema. If successful, this trial will alter infant skin care practices and reduce the burden of allergic diseases in our community. Furthermore, as infants with eczema having a poor skin barrier, which possibly increases their risk of developing sensitisation, we will test if this intervention reduces the risk of food allergy.
The Relationship Between Maternal And Infant Dietary Intake Of Fermentable Fibre, Gut Microbiota, Short Chain Fatty Acids And Allergic Disease And Asthma: A Population-derived Birth Cohort Study

Funding Amount
$871,700.00
Summary
The proposed study will involve the Barwon Infant Study (BIS) cohort of 1074 infants to provide the first systematic investigation of the hypotheses that the epidemic of allergic disease and asthma in many parts of the world relates to the paucity of fermentable fibre in the modern diet, and that the protective effect of fermentable fibre is mediated by changes in the organisms that colonise the gut and the metabolites that they produce.
Modified Peanut Allergen Combined With A Novel Dietary Adjuvant As A Cure For Peanut Allergy: A Randomised Controlled Trial

Funding Amount
$1,130,021.00
Summary
Peanut allergy is common and there is no cure. Current studies of peanut immunotherapy have shown the effects are not generally long lasting with many side effects. We plan to study a novel form of oral peanut immunotherapy using modified peanut and a dietary fibre (modified starch) supplement. We have evidence that modified peanut may work to desensitise patients with less side effects and that the diet supplement protects animals from developing food allergy.
