Yes, there is a whole subsection of the internet that seems to think that vegetables are a net negative. They site doctors that suggest that fiber causes irritation in individuals with compromised intestines (leaky gut syndrome, etc.). It's exhausting having conversations with them as a vegetarian as they seem to think the only healthy way to eat is bone broth, butter, mct oil, and meat.

My doctor told me after an intestinal surgery that I would never be able to eat vegetables again.
