Welcome to Public health moment from the University of Minnesota. Over the last decade, major fast food chains have significantly reduced their use of trans fat in the oils they use to cook french fries and other food. That's according to research from the University of Minnesota's Nutrition Coordinating Center. Lead researcher Lisa Hanak says the center maintains a food and nutrient database that goes back to the 1970s. So we're able to go back in time and look and compare the present with the past. And so we did that with looking at fast food restaurants. And we found that fast food restaurants are making big improvements in the frying oils, with trans fat going down at most of the restaurants as well as saturated fat, either going down or staying the same so that the bad fats in the frying oils at these restaurants is moving in a big way in the right direction. Rna says the findings are relatively good news for consumers who frequent fast food restaurants. But she has a word of caution also. This change is really great from a public health perspective because the average American gets about 10% of their calories from fast food restaurants. So the good news is, if you're someone who eats regularly at fast food restaurants, odds are if you're eating at one of the major chains, the frying oil they're using has a good, low amount of the bad fats in it. Still, though, you need to be concerned when eating at fast food restaurants. So many of the menu items are high in calories, high in sodium. So you know, be watching those things when you're choosing from the menus or choosing a restaurant to eat at. For John Finnegan and public health moment, I'm Mark Gabon.
