"Boiling fruit before you eat it.

(People in medieval times thought raw fruit was bad for you – so they boiled their fruit before eating it. Boiling removes vitamin C from fruit. This habit is thought to be one of the reasons why there were high rates of scurvy in medieval times. One of the symptoms of scurvy is hallucinations. Scurvy-induced hallucinations are thought to be one of the reasons why so many people in medieval times were documented to have had religious visions. LPT – if you want to see Jesus, stop ingesting vitamin C. Possible side effects include loss of teeth, bleeding gums, aforementioned hallucinations, suppression of immune system, and death)."
