While Americans have cut down on trans fats from their diets over the past few decades, we’re still consuming too much.

New research reported in the Journal of the American Heart Association involved a review of six surveys conducted in conjunction with the Minnesota Heart Survey between 1980 and 2009. Over 12,000 adults between the ages of 25 and 74 years were polled in the Minneapolis-St. Paul area.

Lead study author, Mary Ann Honors, an epidemiology researcher at the University of Minnesota School of Public Health in Minneapolis, and colleagues discovered that although Americans have decreased “bad fat” intake, their level of consumption is still too high according to dietary recommendations. Upon review of the surveys, researchers discovered that saturated fats still account for approximately 11.4 percent of daily calories for both men and women.

The recommended daily intake of saturated fats should be no more that five to six percent of total daily calories, according to the American Heart Association.

The researchers also discovered that trans fats make up about 1.9 percent of daily calories for men, and about 1.7 percent for women. According to the American Heart Association, trans fats should be limited to no more than one percent of total daily calories.

“There’s a downward trend in trans and saturated fat intake levels, but it’s clear that we still have room for improvement. To make your diet more in line with the recommendations, use the nutritional panel on food labels to choose foods with little or no trans fats,” said Honors in a statement.
