Nationwide, the average daily consumption of trans fats has gone from 4.6 grams in the 1990s to 1.3 grams in 2010, said Kelley Scanlon, an epidemiologist with the Centers for Disease Control and Prevention. "Things are clearly much better."
However, in a report this month in the Journal of theAmerican Medical Assn., Scanlon and a CDC colleague noted that trans fats are still found in many processed foods, including up to 7 grams a serving in some microwave popcorns. More needs to be done, she said.
