The format for the National Food Guide: performance and preference studies.

This paper gives the main findings of research designed to inform decisions about the format of a food selection guide, subsequently published as the National Food Guide. The research involved 2074 members of the public and 230 professionals involved in nutrition education. Different formats for the guide were assessed for performance (how well the information was understood and recalled) and preference with a quota sample of C2 and D socioeconomic groups.

Extended use of foods modified in fat and sugar content: nutritional implications in a free-living female population.

The nutritional implications of the consumption of reduced-fat and reduced-sugar foods were assessed in nonobese, free-living female consumers in a 10-wk intervention trial. Subjects in control (C; n = 13), reduced-fat (RF; n = 17), and reduced-sugar (RS; n = 19) groups, all initially nonusers of reduced-fat and reduced-sugar products, kept 4-d food-intake records to establish energy and macronutrient intakes at baseline and at 2,4,7, and 10 wk. Groups RF and RS were instructed to use reduced-fat and reduced-sugar foods, respectively, ad libitum in place of habitually consumed foods with traditional composition, whereas group C was to maintain their usual diet.

Eating frequency: methodological and dietary aspects.

It is commonly stated that 'snack' foods provide 'empty calories' and, therefore elevate energy intake whilst providing insignificant quantities of other nutrients. The data presented in the present review suggest that foods which contribute to the pattern of 'snacking' contribute significantly to the nutrient quality of the diet. Those who 'snack' frequently tend to eat more food in general.

Relationships of consumer characteristics and food deprivation to food purchasing behavior.

A large part of domestic food intake may be determined by retail food purchase behavior, and it is commonly believed that this may be significantly influenced by the shopper's state of food deprivation. In the present study, 198 subjects recruited just prior to shopping at a large supermarket completed questionnaires eliciting information on demographic and situational variables, along with measures of time since last eating (TSLE), hunger, and dietary restraint. Upon leaving the store, subjects provided investigators with itemized receipts, having first identified all "unintended" purchases.

Effect of partially depolymerized guar gum on acute metabolic variables in patients with non-insulin-dependent diabetes.

Fourteen patients with non-insulin-dependent diabetes (NIDDM) attended the study centre on 4 mornings separated by at least 3 days, to receive in random order 75 g carbohydrate breakfast meals of control or guar breads with jam and butter. Guar gum flours of low, medium, and high molecular weight (MW) were incorporated into wheat bread rolls to provide 7.6 g guar per meal.
