http://www.slashfood.com/2010/06/17/like-things-salty-you-might-be-a-supertaster/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.
Hayes describes supertasters as living in "a neon food world," while so-called "nontasters" (do we really need to explain who those poor, taste-bud-deprived folks are?) "live in a pastel food world."
So just when you start to think, "Hey, I want to be a supertaster, where every bite is like a stroll down the Vegas strip," here comes the downer: supertasters' penchant for salt may put them at increased risk for things like heart disease and high blood pressure.
That means that studies like this one could have far-reaching implications for public health policy, especially now that salt seems to have replaced trans fat on the food police's version of America's Most Wanted.
In April, the Food and Drug Administration announced a 10-year initiative to cut the amount of salt in processed foods, which could result in federal limits on just how much sodium that manufacturers can put into everything from spaghetti sauce to ice cream.
But if Hayes and his colleagues are right, there may be some snackers out there who would rather have the government pry that can of Pringles from their cold, dead hands than willingly give up salt.
