From the smallest biotech to the biggest pharmaceutical stock, The Motley Fool's Market Checkup covers the health-care sector's biggest headlines, hottest market movers, and Obamacare's ongoing rollout.

In this segment from Thursday's episode, health-care analyst David Williamson discusses trans fats, and a move by the FDA to remove them from the "generally recognized as safe" list. This would then mean that companies would have to apply before being granted permission to include them in foods, and these applications would probably be rejected. David tells investors how this will affect the food industry as a whole, and which companies could be hit the hardest.
