We all eat foods every day and in Western societies we are confronted with a
vast array of different types of foods with different prices, offering different sensory
experiences and of varying composition in terms of nutritional components.
Although the proportion of income spent on food has declined, food nevertheless
remains a major part of an ordinary person’s expenditure and the various
parts of the food industry including production, manufacturing, retail and catering
represent a very significant part of the overall economy.
If we are interested in the nutrition of free-living people then we have to
understand not only what factors influence people’s choice of foods and how
consumers make decisions in relation to the amounts of food eaten, but also the
choice between different alternatives. Likewise, if we are interested in improving
the nutritional status of individuals or populations then we need to understand
what influences choice and how we might impact upon those choices. Since
nutritional intake is a consequence of a complex set of behaviours, the behavioural
sciences, including psychology, have a lot to offer in terms of furthering
our understanding in this area.
The present book brings together insights from a number of sub-disciplines
within psychology and also related disciplines, in terms of what they can tell us
about the influences on human food choice. The book is organized in five main
sections which cover: models of food choice; biological and learning influences
on food choice; societal influences on food; food choices across the lifespan; and
changing dietary behaviour.
One of the difficulties in this area is that because human food choice is influenced
by so many potential factors, there is often a tendency to look at the
impact of these factors in isolation rather than trying to arrive at some overall
understanding of the interplay between different types of influences. The chapters
in the first section present general overviews on how we might conceptualize
the different types of influences on food choice and also bring these together in a
more integrated framework. |
