Doritos are a popular brand of flavored tortilla chips known for their variety of flavors and convenient snacking format. The podcast references Doritos to exemplify how the junk food industry creates products that are cheap, offer many options, and are quick and easy to consume, driving increased consumption.
"Doritos are mentioned as an example of junk food designed for high "velocity" (easy and quick consumption), contributing to overeating and obesity. The speaker discusses the "3 V's" of junk food - Value, Variety, and Velocity, and uses Doritos as an example of that strategy."
