Favism (kyamismos)

& Pythagoras

“abstain from eating beans” ....Pythagoras

Peas from the Pisum genus are nutritious and delicious but potentially dangerous to susceptible individuals. They cause Favism in those who have an inherited enzyme deficiency.1,2,3 In these people, the ingestion of peas from the Pisum genus causes damage to red blood resulting in anaemia and jaundice. The active substance, vicine is found in V. bithynica as well as V. fava (the fava bean). 3

The consumption of beans was prohibited by Pythagoras,  whether it was because for medical, religious, superstitious  or cultural reasons has been debated for centuries. 3,4 It is said that he was caught and slaughtered by his enemies because he refused to cross a field of fava beans. 2
