"What happens if there's a power failure "we protested."And our legs have weakened
because of no exercise."
Some people run,some drive to the gym,and others wear watches to count their steps.
But a few trips up and down stairs after breakfast get my blood flowing and the muscles work-
ing and I'm set for the day.Occasionally my back aches and I'm reduced to a snail's pace.But
speed is no longer a priority.

Picture this:you're at the grocery store feeling satisfied as you reach for the lowfat
yogurt.But then,you find yourself grabbing a pack of sugary cookies.If this sounds famil-
iar,you're not alone.To study the complex dance of healthy and unhealthy choices,a re-
search team conducted two studies.
In Study they lyedeworld purchase dat ve5,000 shopping trips at a
large Dutch supermarket chain.Using handheld scanners,shoppers scanned each product as
they selected it,allowing the researchers to track the exact sequence of their choices.In Stud-
y2,they invited 504 shoppers in the U.S.to participate in an online grocery shopping simu-
lation ()Participants made 25 product choices across various categories.
Across both studies,acebalancing actpatte appeared the relative healthiness of
an initial product choice,was inversely(成反比地)related to the relative healthiness of the
next choice.In other words,a healthier choice was typically followed by an unhealthier one,
and vice versa(反之亦然)。音
The reseacers found that,in thereaorld shoppingatheathierchoices were
balanced out more than unhealthier ones.However,in the online experiment,the opposite
was true-unhealthier choices led to more obvious balancing.
The studies did not account for how much of each product shoppers purchased or con-
sumed.It's possible that the balancing of healthy and unhealthy choices extends beyond just
product selection to serving sizes and consumption quantities as well.Additionally,the stud-
ies were limited to Dutch and American consumers,The generalizability of the findings to
other cultures and food environments remains to be tested.
This research is a reminder that our food choices don't happen in isolation.They're influ-
enced by our previous decisions in ways we may not even realize.Being aware of this balan-
cing tendency could help shoppers make more consistently healthy choices.
