While we need to consume salt, too much can be harmful and is in fact directly linked to ~5% of deaths annually in Australia. We have identified a system in the brain that regulates salt intake. Going forwards we will fully elucidate the pathway(s) implicated in regulation of salt intake, thereby identifying strategies to reduce excessive salt consumption.

Summary
While the scientific evidence base providing the rationale for salt reduction in controlling hypertension is very strong, the data required to translate those scientific insights into policy and reduced population salt intake are mostly absent. Few countries, India included, have the data required to develop, implement and evaluate salt reduction programs tailored to their national circumstances. The overall goal of this 3-year project is to develop the evidence base required to formulate a nati ....While the scientific evidence base providing the rationale for salt reduction in controlling hypertension is very strong, the data required to translate those scientific insights into policy and reduced population salt intake are mostly absent.

International Strategies To Reduce Population Salt Intake

Summary
Effective, sustainable and scalable strategies to reduce salt are needed so countries can achieve the global target to reduce salt by 30% by 2025. This research program will support the optimal development of such strategies through trials and intervention research projects, supplemented through a series of systematic reviews and feasibility and cost-effectiveness assessments. The main outcome will be new evidence on the effectiveness of different interventions to support translation globally.
Salt (sodium) is an essential electrolyte. Our convincing and complementary findings provide compelling evidence for a link between evolutionarily ancient “instincts” and substance abuse. This proposal is translational, including studies in opiate dependent humans. Our studies will establish how and where in the brain endogenous opioids are implicated in the gratification of salt appetite, how salt appetite is altered in opiate dependency and if salt appetite recovers following opiate withdrawal
Evaluating The Effectiveness Of Interventions To Reduce Population Salt Intake

Summary
Eating too much salt is estimated to cause nearly 1 of every 5 heart disease deaths before the age of 70. Almost all people eat too much salt causing high blood pressure. Although health leaders recommend all countries to reduce salt eaten to prevent deaths, there is uncertainty about which initiatives are more effective in getting people to eat less salt. This study will address this by assessing how effective the initiatives in Fiji, Samoa & Victoria are in reducing salt eaten and salt in food
Salt And Cardiovascular Disease: Does Acute Salt-Sensitivity Convey Greater Cardiovascular Risk?

Summary
Salt intake of Australian adults is 10X more than required. Further, salt intake in very young children is alarmingly high secondary to high consumption of salty snacks and processed food. High dietary salt intake has been associated with increased cardiovascular disease and death. We will examine the cardiovascular risks for adults and children on a high salt diet and examine whether switching to a low salt diet ameliorates the high blood pressure and heart disease caused by high salt diets
Role Of AMP-activated Protein Kinase In Salt Excretion And Hypertension

Summary
High blood pressure is a significant health problem and may result from the kidneys not being able to get rid of salt properly. The mechanisms underlying this are unclear. I will investigate the role of a kidney protein, called AMPK, in salt excretion in mice. I will also look at the effects that diabetes and obesity have on the function of this protein. The overall aim is to improve the understanding of what causes high blood pressure which will ultimately aid the development of new treatments ....High blood pressure is a significant health problem and may result from the kidneys not being able to get rid of salt properly.

Summary
Obesity is a significant public health problem, yet some individuals are less susceptible to the development of obesity. High fat eating patterns are commonly associated with overweight/obesity. The taste system is the gatekeeper of digestion and the sense of taste responds to fat, and that the fat taste response is associated with obesity. Using twins as subjects to disentangle the influences of 'nature and nuture', in this project we will identify the mechanisms responsible for linking fat tas ....Obesity is a significant public health problem, yet some individuals are less susceptible to the development of obesity.
