Americans now consume all sorts of ultra-processed foods daily. In fact, they now are the majority of the daily diet of Americans. What many people don't really understand is that ultra-processed foods involve all sorts of laboratory derived chemicals and ingredients.

Neelam Tailor traces the surprising journey of ultra-processed foods from their origins in industrial waste to today's complex ingredient lists and the regulatory loopholes that paved the way.
