Ultra-Processed People

I'm curious about the personal or scientific experiences that led Chris van Tulleken to explore this topic so deeply. Did something specific spark this focus?

The way processed foods are engineered to be addictive or convenient really made me think differently about what I eat. How did others feel about the claims made in the book?

The practical tips seem doable, but I wonder if they are realistic for busy lives. Has anyone tried implementing these recommendations and seen real results?
