Polysaccharides (sugars) and proteins are important constituents to diet, nutrition and health. Diet and nutrition are increasingly becoming recognized as modifiable contributors to the development and progression of disease. Pharmacological management remains the mainstay for the treatment of, for example, diabetes mellitus, a metabolic disorder that results in glycaemic aberrations. Gary and his Team investigate the structural, functional and physico-chemical properties of these polysaccharides (sugars) and proteins and the interactions, therein, in order to establish the tangible health benefits these naturally-derived molecules offer and how newly designed delivery systems for these constituents can offer improved bioavailability
