Kale can cause dangerous blockages in rare cases, and high-fiber diets trigger inflammation in some people. The speaker argues against universal health claims and pushes for personalized nutrition instead of one-size-fits-all advice.
For some people, kale is just fine. For others, it's higher risk for a phytobezoar, a structure that lodges in the gastrointestinal system, kind of clogs it up. And a difficult lesson I learned during my radiology rotation when I saw some really striking images. But to cite some hardcore data, there are studies showing that fiber can be inflammatory in some people. Now, while this is a minority group, they do matter. And if for some, dumping a load of fiber into the system can actually make health and inflammation worse, then really we should stop with the platitudes like "fiber is essential for gut health." It's not. So instead of thinking good versus bad, think right food in the right person at the right time.
