Variety, palatability, and obesity
Johnson & Wardle (2014) here argue that although food palatability and variety have been repeatedly shown by human and animal studies to heavily influence appetite stimulation, satiety (feeling of fullness) delay, and the promotion of excessive energy intake, there is a limited amount of evidence estimating how strongly the weight of an individual human being is affected. In addition, the paradigm in the laboratory is not the same as the eating environment in a natural setting. Past studies have revealed that both food palatability and variety have a significant impact on short-term food consumption, with their increases linked with weight gain also in animal models. But the authors note that there are individual differences in vulnerability to the palatability effect, which can determine how likely the individuals are to gain weight. While the knowledge on how palatability and variety interact with eating is progressing, more intervention and epidemiological studies are needed to confirm whether controlling the surrounding food environment is crucial to tackling this obesity crisis, and for these laboratory findings to be considered and applied by public health.
