this post infers possible causation based upon a sample size of 1

Eh? Pica is a known disorder. The sample size for the causation claim is clearly more than 1.

[ETA: In case anyone's wondering why this comment no longer makes any sense, it's because most of the original parent was removed after I made it, and replaced with the current second para.]

EDIT: The claim that Pica is a known disorder is distinct from claims about what causes it. The only evidence given in the post is one personal experience. However, the wikipedia article does state that

scant research that has been done on the causes of pica suggests that the disorder is caused by mineral deficiency in many cases, typically iron deficiency

referencing a study which states that:

Pica is probably a behavior pattern driven by multiple factors. Some recent evidence supports including pica with the obsessive-compulsive spectrum of disorders. Many different treatment regimens have been described, with variable responses. It is important to be aware of this common, but commonly missed, condition.
