New research from the University of Sydney’s Charles Perkins Centre reveals bottle-feeding, climate change and economics could be among the causes of obesity.
Surprising new leads uncovered in global obesity epidemic. December 2014 - Researchers have uncovered surprising new leads in the worldwide obesity epidemic by examining the combination of our rapidly changing environment with our overwhelming appetite for protein. Published in the British Journal of Nutrition, the research from the University of Sydney's Charles Perkins Centre indicates that bottle-feeding, climate change and corporate bottom lines could be among the dark horses of global obesity. The new leads were uncovered by comparing what is known as the Protein Leverage Hypothesis against our changing environment. The Protein Leverage Hypothesis, developed by Charles Perkins Centre researchers as part of a major breakthrough in nutrition research, identifies our overwhelming appetite for protein as the driving force behind appetite in humans and numerous other animals Increased atmospheric carbon dioxide, an explosion in ultra-processed foods, and high-protein diets in early life, for example through baby formula instead of breast milk, could all play a role in the world's expanding waistline. "We have developed a new approach to the obesity issue, which involves the use of geometry to understand nutrition," said lead researcher Professor David Raubenheimer, the Leonard P Ullmann Chair in Nutritional Ecology at the Charles Perkins Centre and a Professor in the Faculty of Veterinary Science and School of Biological Sciences. "The new geometric approach has produced intriguing leads on what might be contributing to the obesity epidemic.
