Ultra-processed foods are bad for human organs, study finds

In the US and the UK, over half of the foods eaten in a typical diet are ultra-processed. That is, packaged foods significantly altered from their natural state, with many added ingredients, artificial colors. A study just published in The Lancet journal shows the extent of the damage being done by excessive consumption of these foods, and looks at their role in people's diets from one part of the globe to another. Barry Popkin of the University of North Carolina is one of the lead authors of the study. He joined Host Marco Werman to share the major takeaways.
