Phantom fat is hiding in your cereal bowl. It's the bad boy in your bag of microwave popcorn. It lurks in those low-fat cookies and even in that energy bar.
The stuff is called trans fat, created when ordinary vegetable oil is processed into partially hydrogenated oil. It's why Crisco stays solid at room temperature and what makes cakes moist, cookies fresh and crackers crisp. Partially hydrogenated oil is in about 40 percent of the food at the grocery store, including some products most consumers regard as healthy.
A generation ago, when cardiologists waved Americans off saturated fats like butter and beef tallow, partially hydrogenated oils became a preferred alternative. Now, in an about-face, researchers have determined that trans fat can grease the way to a heart attack faster than a cup of lard.
Some of the nation's leading medical researchers, including many in the Bay Area, also believe that the trans fat that marbles the modern American diet may be why kids are so fat, diabetes is at record levels and why some people develop cancer. They say trans fat is a big player in Syndrome X, a cluster of health problems characterized by a beer belly, high blood pressure and out-of-whack blood fats and sugars.
"There should be a warning on food made with this stuff like there is on nicotine products. It's that bad for you," says Dr. Jeffrey Aron, a University of California at San Francisco professor of medicine and one of the nation's leading experts on fatty acids and their effects on the body.
But there is no warning label. Trans fat amounts aren't regulated at all, so manufacturers and fast food operators don't have to list it on nutrition labels. That means there's no easy way to know how much you're eating.
And chances are, it's a lot more than you think.
Virtually every fast-food or family restaurant french fry is cooked in trans fat-filled grease. Almost half of all cereals, both cold and hot, contain it, according to the Food and Drug Administration. So do 70 percent of cake mixes, 75 percent of chips and other salty snacks, 80 percent of frozen breakfast foods like waffles, and 95 percent of cookies.
