Nabisco has reformulated some varieties of Oreo to leave out trans fats.
Some companies have already begun to reformulate their products, including varieties of Nabisco's Oreo cookies, to leave out trans fats.
Beginning in 2006, the Food and Drug Administration will require food makers to include information about trans fats in food labels. The fats, found in foods like cookies, crackers and chips, provide taste, consistency and a long shelf life, but they're bad for the heart. Some say the labels won't affect consumer choice, yet several manufacturers are already reformulating their products. NPR's Snigdha Prakash reports.
