The government has announced new rules aimed at giving people a better picture of what they're eating.
The Food and Drug Administration is unveiling regulations requiring food labels to list the amount of trans fat in each food.
Trans fat hasn't gotten the attention of its more well-known cousin saturated fat -- but health experts say it's just as dangerous to the heart as saturated fat.
FDA Chief Mark McClellan says the new label requirement means trans fat can no longer -- in his words -- "lurk, hidden, in our food choices."
Health Secretary Tommy Thompson says trans fat is all too common. An official with the Center for Science in the Public Interest calls the new rule a "good first step." But she cautions the labels won't tell how much of a particular product counts against a person's daily allotment of total unhealthy fat.
The group had petitioned the F-D-A ten years ago to make the label change.
Trans fats are used in foods to make them taste better and to increase their shelf life. The FDA believes if people would eat less of them, at least under 20 grams a day, more than 5000 lives could be saved.
The feds say the fat is causing heart disease and makes people fat.
Frito Lay is already labeling trans fats on their products, and Kraft will follow suit.
You can do label math to find out the number of trans fats as well. Just add the number of saturated fats, mono saturated fats, and polysaturated fats. Then subtract that number from the total fat. That number equals the number of trans fats a product has in it.
