A current topic of interest is consuming avocado pits. While there are purported health benefits, there is not enough research to back up those proposed benefits.
Penn State University did some research and state “although the currently available data is promising, for most indications, it remains very preliminary and further studies are needed” and “In addition, the safety of the various extracts of the avocado seeds must be assessed in order to more fully estimate the usefulness of this resource.”
Therefore, it is not recommended to consume avocado pits.
