Conventional Wisdom Can Be Quite Wrong
For virtually all of my adult life, I had heard that the human appendix is an evolutionary vestige that no longer served a useful purpose. When it gets infected, as sometimes happens, you just take it out. In addition, I had always heard that the purpose of fat cells was energy storage for the lean times. Other than that, fat is bad. Recent scientific discoveries have revealed how very wrong this conventional wisdom has been – a different kind of medical reversal.
In the past decade, research has confirmed that that the appendix plays a key role in the development of the human immune system, and in serving as a repository for good gut bacteria. When dysentery or flu depletes the micro biome of the human gut, the appendix can help re-establish it once the illness has run its course. Perhaps more significantly, lymph tissue accumulates in the appendix after birth and helps train the immune system and its systemic response to threats. It is remarkable to realize that these functions were undetected just a few years ago.

As for fat tissue, it turns out that fat tissue is a complex human organ and is a rich source of stem cells – more so even than bone marrow. Stem cells have the ability to divide and grow into a wide variety of tissue types. Fat stem cells have been shown to grow into bone, cartilage or muscle tissue, and researchers are now exploring the opportunity to treat injuries or damage in these tissues with a patient’s own fat tissue. This is certainly a lot deeper story than the one reflected in conventional wisdom. See: Fat Cells Mend Bone, Cartilage and Muscle, Science News (2016).
These are good reminders that the truth is not always what we think it is.
