Food shopping practices and family health

"The way in which a family selects, obtains and stores food has a major impact on diet. This includes who in the family makes decisions about food and how, who does the shopping and where, whether they stick to a pre-determined plan or buy whatever looks good at the time, and how much influence the shopper's knowledge of the health effects of diet has on shopping practices. Ways in which shopping practices could be changed - with a high likelihood of compliance over the long term - to improve the family's diet were considered as an exercise in medical education."
