Declining consumer confidenceraises the likelihood of additional Americans taking on the shopping behaviorof low-income consumers, says global consulting and research firm PromarInternational.  "The souring consumer outlook on the economy ultimatelyaffects food sales," according to Promar senior consultant, John Kauke.  "Itdoesn't get as much media play as the big-ticket manufacturing sectors, butindividuals and families hit with pink slips or the threat of one will adjusttheir food dollars accordingly.  They will still buy food, of course, but theymay go about it in a way that tracks more closely with the behavior of low-income US consumers."
