Aim: Dietetics as a form of study predates medicine, but the profession did not emerge until the nineteenth century and is still in an emergent stage today in many parts of the world. This paper seeks to demonstrate how the impact of leaders has been critical in terms of the growth and development of the profession. Methods: A narrative review was formed from searching the published literature. Results: The published literature is silent on many aspects of dietetics. In modern times, the majority of written works have come from North America and Western Europe. No work on historical or developmental aspects of dietetics from other parts of the world could be located. Leadership within the profession is well researched, but leadership by the profession in the broader arena of national and international policy and practice is harder to identify. There are calls for curricula to keep pace with the needs of modern healthcare systems if the profession is to flourish. Conclusion: Despite all the changes and the evolution of the profession, much remains unchanged. There are recurring themes throughout the literature reviewed here, those of the breadth of dietetics, the need for evolving curricula, the need for business acumen, the need for diversity and, in more recent times, the ability to work with interdisciplinary teams. But the profession has what it takes. It has within its ranks leaders of today and tomorrow. It is up to the profession to allow those leaders to emerge and take the profession to the next level.

Aim: To undertake a systematic literature review to examine the effect of food cost on diet quality and risk factors for chronic disease, specifically focusing on diet-related lifestyle diseases affecting the Australian population. Methods: A search of six databases resulted in the inclusion of one systematic review, three cohort studies, 41 cross-sectional studies and four modelling studies in this review. Results: Between 2000 and 2006, the price of healthy foods has increased more than the price of less healthy foods. Healthy Food Access Basket surveys show that a healthy diet may often be unaffordable for low- and average-income households. Diets of higher energy density were associated with lower diet cost, whereas diets of higher nutrient density and nutritional quality were associated with higher diet cost. Recent studies report an inverse association between food price and food consumption. Consequently, an increase in food cost was associated with a significant reduction in weight, waist circumference, body mass index, obesity and insulin resistance. Conclusions: Manipulation of food cost may alter food consumption and therefore risk factors for chronic disease. Further longitudinal studies investigating the impact of pricing strategies on diet quality and disease risk are needed. [ABSTRACT FROM AUTHOR]
