One important fact about the DHKS is that it is the first survey designed to link dietary attitudes and food consumption on a nationwide basis.
These findings are generally consistent with attitudes revealed by the DHKS.
The DHKS does not break out data by family size, but it does have data comparing the knowledge and attitudes of male and female meal planners.
The DHKS shows that 54 percent of all main meal planners believe that their diets should be lower in fat, and this may be one reason for the decreased probabilities of purchasing the aforementioned foods.
These findings are consistent with results of the DHKS which indicate that, of all meal preparers, those under age 39 are most likely to believe that their diet should be lower in fat (60 percent) and, specifically, saturated fat (52 percent).
This finding is consistent with DHKS results which show an increasing relationship between the age of the meal planner and the percentage of the group that places a high importance on limiting fat (especially saturated fat) and cholesterol intake.
The DHKS results show a smaller spread across income groups in concerns about fat and cholesterol intake than they do for age groups,(57) so it is not surprising that there is very little difference in probabilities of purchasing among income groups.
The DHKS shows that women are slightly more concerned about fat intake than are men.
The DHKS survey gathered much useful and never before collected information on households' food consumption behavior, health and nutrition knowledge, attitudes, and habits.
