Correcting the (Pictorial) Record on Trans Fat

This week, the U.S. Food and Drug Administration (FDA) announced its determination that partially hydrogenated oils (PHOs) are no longer generally recognized as safe (GRAS) for use in foods (1), and food companies have three years to replace them with something else. Accompanying many of the news stories about the FDA determination are images of foods that presumptively contain PHOs and, therefore, also contain some amount of trans fat. That’s where the news stories go awry in their "worth-more-than-1,000-words" pictures.

As a whole, the potato industry ditched PHOs nearly a decade ago, and there are plenty of published peer-reviewed studies to prove it (2-4). Studies by the FDA and the Centers for Disease Control and Prevention (CDC) show that potato manufacturers led the way in virtually eliminating the use of PHOs and reducing trans fat by 88% in retail frozen potatoes. This was the fastest and largest reduction in trans fat compared with any other food category (5,6). Most major quick service restaurants also shifted to trans fat-free oils in 2007 (7). In its 2013 request for comments concerning the tentative determination that PHOs were not GRAS, the FDA acknowledged that frozen potato products had already been reformulated to remove PHOs (8).

It’s important that news stories accurately reflect the science in both words and pictures. French fried potatoes removed PHOs long ago, are not a significant source of trans fat and, therefore, should not be the eye-grabbing "centerfold" in this story.
