 Previous research has suggested that food structure and food composition has a role to play in controlling consumption. Low-energy, high-fibre diets provide physical bulk in the gastro-intestinal tract to sustain fullness in a way that low-volume, energy-dense foods cannot. However, studies shown low long term acceptability be probably associated to its poor palatability. Taste and hedonic experience remain the main drivers of consumer choice, and the immediate sensory aspect of food products such as palatability to have greater salience to consumers than their health promoting properties.
