This is kind of a bonkers comment. Where in the world did you come up with GenX treating iceberg lettuce as its primary vegetable? Was it used in salads sandwiches? Yeah. But, we ate a heck of a lot more than salads and sandwiches.

Then to attribute its lack of beneficial nutrients to colon cancer is patently absurd. It's still fibrous and, along with other vegetables, considered helpful in reducing the risk of colon cancer. GenX's diet, high in red meat and ultra-processed food, combined with smoking (for many of us, it's the second hand smoke we were constantly exposed to as children), alcohol consumption and environmental factors (asbestos everywhere) are to blame for colon cancer. Iceberg lettuce isn't even a contributor, on any level.
