Transcript for New study looking at what ultra-processed foods can do to our waistline
In today's "Weekend download" why going natural is better. A new study looking at what ultra processed foods can do to our waistlines. ABC's chief health correspondent Dr. Jen Ashton is here. Thanks for joining us as always. We should also point out we're doing this on barbecue day in the studio but not all barbecue is processed. Right? Okay, so just to be clear explain what ultra processed foods are. So they're the foods, a lot of them that are right in front of us, chips, candy, white bread, even some breakfast cereals. They are typically very high in fat, salt and sugar. They are what we call nutrient poor and calorie dense and basically they're the things that we buy in the grocery store that can be stored in our pantry long shelf life. Basically they can withstand a nuclear holocaust and they're not good for us. Sadly they're some of my favorite things so have to hold back a little bit. We're going to have to talk about that. Tell us about the study. What do the findings reveal? Whit, this was a very, very important study funded by the national institute of health. It was very small but incredibly good methodology, very well they followed people in direct observation over a four-week period of time and matched them calorie for calorie and found that the group that ate ultra processed food gained a pound a week and they were hungrier and they ate more, so, again, if they're eating the same amount of calories there's something in these foods that changes our body's hormone, the way we eat and it's a problem. You notice that. You open the bag of chips and can't stop. You keep going back. Ultra processed food is often cheaper. Yep. It's easier to prepare. How do we resist the temptation to buy it in stores? Listen, whit, as a doctor and nutritionist, my advice is as much as possible eat from the farm, not the factory. Your waistline will thank you and your body will be healthier. All right, and we thank you as always. Dr. Ashton, great to see you. Thanks for bringing this good information.
