The U.S. government is about to define what junk food is. But comparing soy milk and gummy bears is complicated.

This move aims to reshape dietary guidelines for federal assistance, potentially altering consumer spending habits and forcing food companies to reformulate products. The complexity arises in establishing clear, universally accepted criteria, as differentiating between seemingly disparate food items like soy milk and gummy bears based solely on nutritional value can be nuanced.
