Vani Hari: For years, Starbucks didn't publish their ingredients for their coffee drinks

"For years, Starbucks didn't publish their ingredients for their coffee drinks. It was a mystery until I convinced a barista to show me the ingredients on the back of the bottles they were using to make menu items like their famous pumpkin spice lattes. I found out here in the United States Starbucks was coloring their PSLs with caramel coloring level 4, an ingredient made from ammonia and linked to cancer, but using beta carotene from carrots to color their drinks in the UK.
After publishing an investigation and widespread media attention, Starbucks removed caramel coloring from all of their drinks in America and started publishing the ingredients for their entire menu.
I want to make an important point here. Ordinary people who rallied for safer food shared this information and signed petitions were able to make these changes. We did this on our own. But isn't this something that the people in Washington, our elected politicians, should be doing?"
