The diets of young women are important not just for their own health but also for the long-term health of their offspring. Unbalanced unvaried diets are more common amongst poor and disadvantaged women. If the diets of these women are to be improved, it is first necessary to understand why they make the food choices they do. Influences on women's food choices range from the global to the individual: environmental factors, such as difficulty in acquiring and affording good-quality healthy foods; social support and social relationships, such as those with parents, spouses and children; life transitions, such as leaving home, living with a partner or having children; individual factors, such as having low perceived control or self-efficacy in making food choices and placing a low value on health in general and on their own health in particular. These interrelated factors all influence food choice, suggesting that if the diets of disadvantaged women are to be improved, it will be necessary to do more than simply educate about the link between diet and health. The present paper aims to review the range of factors that affect the food-choice decisions made by disadvantaged women as a step towards meeting the challenge of improving the health and nutrition of disadvantaged populations. The diets of young women are important not just for their own health, but also for the long-term health of their offspring (1,2) . Unbalanced and unvaried diets are known to be detrimental to the growth of babies (3)(4)(5) and are more common in disadvantaged women (6,7) . Women of lower educational attainment are much more likely to eat a poorquality diet than women of higher educational attainment (8) . Improving the diets of disadvantaged women before and during pregnancy may hold the key to breaking the cycle of disadvantage and ill health suffered by the poor in Britain today.
Understanding food choiceInfluences on women's food choices range from the global to the individual. Global influences are shaped by the productionist paradigm of food provision, which in today's developed world means extensive food choice is available to individuals who have the necessary resources (9) . These resources include money, access to shops, time and the knowledge required to choose and prepare the variety of food products on offer. The negative side to the extensive range of foods available is that many of the cheapest easiest-to-prepare 'convenience' foods are high in saturated fats and sugars, which are undesirable in a healthy diet. The choices an individual makes are going to be determined partly by what retailers offer.Macro-environmental influences will vary according to local community and social circumstances shared by individuals living in similar situations. Micro-environmental influences such as family dynamics will affect the choices made by the household. Individual influences, such as preferences, will determine who eats what within that household. To make food choices individuals need to consider what, how, when, where and with whom ...
