Not all eating habits are made alike. Some routines may even be
beneficial, new study says
A new study on eating habits, forthcoming in the March 2006 issue of the
Journal of Consumer Research, reveals that not all eating habits are
made alike. Adwait Khare (University of Houston) and J. Jeffrey Inman
(University of Pittsburgh) identify two ways of characterizing eating
habits, which they termed "carryover habit" and "baseline habit." Their
findings have important implications for nutritional guidelines and meal
Carryover habit describes meal decisions affected by previous meals. The
authors found that what we eat at a meal – say, breakfast – is more
influenced by what we ate at the same meal the previous day than by the
other prior meals. Breakfast has the strongest "carryover effect,"
possibly because we have less time to decide what to eat for breakfast
and the most consistent environment for this meal.
Since we tend to eat more "good" nutrients, like calcium, at breakfast
and more "bad" nutrients, like saturated fat, at dinner, this carryover
might actually be beneficial. However, when the authors examined how
much of each nutrient tended to be consumed at each meal, they found
that people with a "baseline habit" consistently varied how much of each
nutrient they ate according to what meal it was.
"Daily meals are associated with different food values," write the authors.
The authors suggest that instead of providing daily nutritional goals,
we might want to embrace multi-day nutritional goals, taking into
account how one day's meals affect the next day's meals. Also, knowing
that we tend to approach dinner with a different set of habits, can help
us look at nutritional goals with more clarity.
