Sugar is a naturally-occurring plant product and is refined primarily from sucrose (glucose and fructose) found in cane and beets, but can also be a product of corn, tree saps, bees (honey), fruits (dates and coconuts). Vilified by some nutritionists when it makes up more than 10% of dietary energy, it is also greatly sought by humans for its hedonic and rewarding properties. This symposium discusses the biology behind our love of sugar and explores the potential epigenetic aspects of sugar as a trigger for obesity. Public health efforts at reducing sugar consumption consist of excise taxes, simplified food labeling, and partnerships with producers to reformulate products. These will be discussed and evidence for success or lack of it in reduced intake and reduced obesity prevalence in children and adults) will be reviewed.

This session was jointly produced by The Obesity Society (TOS) and World Obesity Federation (WOF).
