A paper titled Nutritional Ecology and Human Health, published by David Raubenheimer and Stephen J. Simpson from the Charles Perkins Centre and School of Life and Environmental Sciences, The University of Sydney says the way we measure the health impacts of the human diet needs to be reconsidered.
Simpson says “Conventional thinking which demonises fat, carbohydrate or sugar in isolation as causes of the obesity crisis — dubbed the single nutrient approach — has now run its course. We’ve provided a framework for not only thinking about but also experimentally testing issues around dietary balance. Much like the invention of the telescope or microscope, this framework offers a new tool with which to look at complex dietary problems and bring them into focus”.
