And another one bites the dust! Yum Brands, Inc. announced this week that two of it's restaurants -- KFC and Taco Bell -- have switched to trans fat-free oils in their restaurants. KFC and KFC/Taco Bell combo restaurants will be using a soybean oil and Taco Bell will be switching to canola oil. Both restaurants still have items on their menus that contain trans fats -- such as biscuits and baked goods -- but the change in oil will affect several popular items.

Trans fats have been shown to raise bad cholesterol and reduce good cholesterol. Restaurants, food manufacturers, and even entire states have been dropping it like a hot potato. But before you run out for a "healthy" bucket of trans fat-free chicken, don't forget to consider the saturated fat and calories. KFC and Taco Bell have improved the health of their products for sure, but they are still selling fast food after all.
