Remember the old potato chip slogan, "No one can eat just one"? Well, it turns out there may be a granule of scientific truth to that bit of advertising bravado -- for some of us, at least.
According to a study published this week in the journal Physiology & Behavior, some people appear to be genetically hardwired to enjoy saltier foods than others. So-called "supertasters" are people who experience all tastes more intensely (sweet, bitter, salty), and the participants in the study who were identified as supertasters reported eating saltier foods.
"Most of us like the taste of salt," said John Hayes, a food researcher at Penn State and one of the study's authors. "However, some individuals eat more salt, both because they like the taste of saltiness more, and also because it is needed to block other unpleasant tastes in food," such as bitterness.
